Experiencing Culture Shock
A When Eliza James arrived at the University of Xian she was excited to live in a new country to improve her Chinese and to experience a culture so different from her own But soon her excitement turned to frustration as she encountered one roadblock after another I felt like I couldn＇t accomplish anything My dorm room had no heat I couldn＇t get into the classes I wanted and every time I asked someone for help they gave me the runaround I felt like no one was listening to me Eliza met with administrators sent letters of complaint and even contacted the consulate in Beijing but she got nowhere What Eliza didn＇t realize was that her American approach to solving problems was very different from the Chinese one in which patience and negotiation skills are key She soon learned how to solve problems within the cultural norms of Chinese society instead of forcing her own values onto those around her I finally feel like I fit in and that I know what I＇m doing In fact it＇s really fun being in a place that＇s so incredibly different from what I am accustomed to
B Yoshi Yamamoto is a junior at a small college outside of Boston Although he is an honors student now Yoshi didn＇t always have such an easy time studying in America Teaching methods are very different here than they are in Japan It took me a long time to get used to learning in seminars and discussing ideas with my classmates At first it seemed like I wasn＇t actually learning anything Yoshi＇s reaction was to totally withdraw he didn＇t participate in class discussion he spent lots of time alone in his room and he even skipped class on occasion I thought I could teach myself Now I recognize the value of the US academic system and I am able to adapt it to my own learning style
C Both Eliza and Yoshi experienced what is called culture shock psychological disorientation due to living in a new culture For many international students studying abroad can offer exposure to new cultures and an opportunity to study new fields and languages However it also offers the greater challenge of trying to function in a foreign culture Studying and reading about a certain culture is poor preparation for the reality of living in it According to psychological studies the four stages of culture shock are 1 euphoria 2 hostility 3 gradual adjustment and 4 adaptation Culture shock can be manifested in many ways homesickness boredom stereotyping of or hostility towards the host culture overeating or overdrinking withdrawal and inability to work effectively
D Different people experience different levels of culture shock and react in different ways For example Eliza got angry while Yoshi withdrew from society The most important thing to remember is that culture shock is normal it is not something to be ashamed of Luckily there are some things international students can do to make their adjustment to a new country go more smoothly For instance they can stay in touch with family and friends from home join international student organizations meet people from their own countries and get involved in campus activities Most importantly they can adjust to life abroad by keeping a sense of humor and trying to remain positive

Seasonal Affective Disorder More than Just the Blues
A Joshua dreads the winter months not only because of the cold New England weatherthe sleet snow wind and rainbut because as the seasons change from summer to fall to winter the days get shorter As the days get shorter he starts feeling depressed and irritable and spends more and more time at home eating and sleeping A graduate student in philosophy Joshua finds that he gets little work done during the winter months and has trouble paying attention in class and concentrating on his research I soon realized that what I thought was just the ＇winter blues＇ was something more extreme than that Josh visited a doctor who diagnosed him with SAD
B Seasonal Affective Disorder or SAD is a kind of depression that occurs seasonally It is associated with the long hours of darkness and lack of sunlight during the winter months (people with SAD usually feel worse from December through February) Scientists don＇t completely understand the exact causes of SAD but they believe it is related to a biochemical imbalance in the hypothalamus The hypothalamus is the basic part of the brain that controls the body＇s breathing heartbeat metabolism and hormone release The effects of SAD include moodiness irritability low energy increased appetite for carbohydrates (foods such as potatoes rice and bread) difficulty concentrating and the tendency to oversleep
C Although doctors described SAD for the first time in 1984 humans have probably dealt with the disorder for thousands of years It is not a coincidence that many cultures have important celebrations during the short days of the winter months Christmas Hanukkah and Winter Solstice celebrations all occur in December These celebrations involve lighting candles in order to bring light warmth and happiness to an otherwise depressing time of year
D So what can SAD sufferers do to feel better Naturally they need more light For people who have mild cases of SAD exercising in the morning sun could be enough to help them Phototherapy or light therapy is usually prescribed for people who have more serious cases of the disorder In light therapy patients sit in front of a light box a strong artificial light for up to four hours a day Phototherapy is effective in over 80 of SAD cases and patients usually see results within three to four days Although the symptoms of SAD are similar to those of clinical depression traditional antidepressants have not proven useful in treating SAD While psychological counseling cannot treat the symptoms of SAD it is recommended to help SAD sufferers learn to accept and deal with their illness

changes damaging losing global available
The growing similarities in diet and eating habits around the world are influencing people of various cultures in different ways For example Western foods are 6 damaging health in the industrialized island country of Japan Instead of small meals of seafood rice and vegetables the typical Japanese diet now includes large amounts of meat dairy products and desserts like tiramisu a rich Italian dish full of chocolate cheese and sugar According to Japanese health researchers such 7 changes in eating habits are related to a great increase in health problems such as heart disease strokes cancer and diabetes On the other hand the changing 8 global diet is having the opposite effect on the people in the CzechRepublic The government of this European nation no longer supports meat and dairy products financially so the cost of these foods is going up In contrast fresh fruits and vegetables are becoming more widely 9 available from private markets and stands Cooks are even serving salads to schoolchildren and families are eating healthier homecooked meals For these reasons fewer Czech men are having heart attacks the women are 10 losing a lot of weight and most people are living healthier lives

Complete the following statements by choosing the best from the answers A B C or D (1 point each)
These days it’s getting easier and easier to find your way around Some people have GPS devices in their cars to make sure they don’t get lost GPS stands for Global Positioning System These devices use satellites in space to see where you are and give you directions to where you want to go And if you don’t have a GPS device you can simply go online to get stepbystep directions Websites like MapQuestcom and mappointmsncom can produce a map and directions in just a few seconds But how do they do it
MapQuest® uses data (information) from a few different sources to produce directions and maps Before MapQuest® went online it sold regular paper maps in places like gas stations The website uses the data from those paper maps information from digital mapping companies and government databases At the moment MapQuest® uses more than 30 computers to read all this data and provides users with millions of maps every day
In order to find the best route (way or path) from one place to another MapQuest® first has to look at all possible routes Then MapQuest® looks at each part of each possible route It considers the types of roads on the different routes Are they dirt roads paved roads freeways or city streets It looks at how many turns there are in each route and what kinds of turns they are Are they right turns or left turns It also considers the speed limit on each road and how many intersections there are An intersection is a place where two or more roads cross each other
MapQuest® can also tell you how long your trip will take you It does this by doing some math MapQuest® bases its estimated driving times on the length and speed limit of each part of the route and the amount of time it probably takes to get through each intersection For example it allows more time for a left turn at an intersection than it does for a right turn Someday maybe we will have cars that can just drive us wherever we want to go but for now mapping websites make it a little harder to get lost

选择项：
C How mapping websites work

7According to the article MapQuest®______
选择项：
D starting by selling paper maps

D look at all possible paths
题目5
9When it’s deciding on the best route MapQuest® probably chooses ________
选择项：
C freeways instead of dirt roads
题目6
10 To estimate your driving time MapQuest® considers _________
选择项：
D the speed limits and types of turns on your route

The Family of the Future
Many people today would like the traditional twoparent family back—that is to say they want a man and a woman to marry for life they also think the man should sport the family and the woman should stay home with the children However few families now fall into this 6 category In fact if more women decide to have children on their own the singleparent household may become more 7 typical than the traditional family in many countries Also unmarried couples may decided to have more children—or they might take in foster children or adopt And because people are staying single and 8 living longer (often as widows) there may be more oneperson households in the future On the other hand some people 9 believe similar events happen again and again in history If this is true people may go back to the traditional 10 extended or nuclear family of the past Others think the only certainty in history is changing in other words the structure of the future family could begin to change faster and faster—and in more and more ways

Everyone makes mistakes or so the saying goes But have you ever heard about mistakes in Hollywood When most people think of Hollywood they think of blockbusters (very successful movies) highpaid actors glitz and glamour But according to one Website many Hollywood movies are full of mistakes Some are technical errors For instance in a scene of the sciencefiction adventure film The Matrix when the main character steps out of his car the viewer can clearly see the camera crew in the car window In another scene the same character is typing on his computer yet the computer screen is blank Other movie mistakes are historical For example the epic Gladiator an Oscar winner is known for having lots of historical errors Throughout the movie the gladiator Maximus refers to his home in Spain and the other characters call him the Spaniard However in 180 AD when the movie takes place Spain as a country or even as a concept didn＇t exist yet At another point in the movie Maximus says that his homeland of Spain has the best horses But horses weren＇t brought to the Iberian Peninsula until the invasion of the Moors (North Africans) in 711 AD more than 500 years after the movie takes place The historical drama Titanic another Oscar winner also has its share of historical blunders The Titanic sunk in the year 1912 So why is one of the characters wearing a digital watch In fact movie watchers have found over 100 mistakes in The Matrix Gladiator and Titanic Can you think of any errors in your favorite films

How susceptible are you to advertising Has a TV commercial or magazine ad ever made you buy the product that was advertised If so perhaps you have been subjected to subliminal advertising Subliminal advertising is a kind of advertising that appeals to the subconscious The word subliminal comes from the Latin sub meaning lower beneath or under and limen meaning threshold (the level at which something begins to happen) Thus subliminal advertising stimulates your brain at a level below conscious perception You cannot see hear or perceive subliminal ads but they may affect you just the same
There are two main types of subliminal ads The first involves flashing messages quickly during a commercial or film The messages appear and disappear so rapidly that the mind cannot process them consciously but it might receive them passively at a subconscious level James Vicary a market researcher first introduced this kind of subliminal advertising in 1957 when he flashed the words Eat Popcorn and Drink CocaCola every five seconds during a movie The messages couldn＇t be seen yet Vicary claimed that the moviegoers＇ brains could perceive them Coke sales went up by 18 and popcorn sales by over 50 More recently the same type of subliminal advertising was used in a negative ad for a political campaign In the ad the word rats flashed up briefly during the part of the ad describing one party＇s healthcare plan The purpose was to associate that opposing party with the negative word rats The second kind of subliminal advertising involves hiding or incorporating images into visual advertisements A wellknown example is on a package of a famous brand of cigarettes Some say that if you look closely you can see the image of a man who is sexually aroused In fact a lot of subliminal advertising involves sex coming from the idea that sex sells One media researcher claims that everything from crackers to alcohol to soda has used subliminal sexual imagery to appeal to buyers
Although studies show that consumers believe strongly in the power of subliminal ads no one can prove the effects of subliminal advertising Psychologists and others who study subliminal stimuli have not been able to show that subliminal advertising actually works Many advertising researchers believe that traditional ads in which a powerful image is used to sell a product are more effective than subliminal advertising All the same it still remains a controversial topic one that is on the mind of buyers and sellers alike

Meeting the Perfect Mate
What is the best way to meet the perfect husband or wife I am continuing to interview students on campus trying to answer this question for my sociology class So far people have mentioned arranged matches discos and bars computer dating services and personal ads One guy even said he thought supermarkets were the best places to meet women I guess you can talk a lot about a head of lettuce
I decided to go to the school cafeteria to interview some people there
I think date cafés are the best way to meet people said my friend Rahul
Date cafés What＇s that I asked
Well a date café is both a café and a dating service You go to the café order a cup of coffee or whatever you want and look through people＇s profiles Then if someone interests you you can send him or her an email and arrange a date at the café You can also fill out your own profile and have people email you The form asks you about everything from looks to interests to religion The date café is a relaxed way to make contacts
Are there many of them around I asked
Hmm Well there＇s one near campus called Drip In fact I had a Drip date just last week said Rahul
Drip But isn＇t that a word that＇s used to describe someone who is dull and boring It doesn＇t sound too promising
Yeah well it＇s funny you say that because my date was pretty uninteresting She barely talked at all and she kept looking down at her coffee mug
Well what about a mail order bride said Rahul＇s roommate Joni
A what I asked
A mail order bride You know you search for your wife in a catalog and the next thing you know you＇re married With the Internet it＇s easier than ever she said
Ugh that sounds awful I said Have you ever met anyone who has done that
Yes my uncle did it His marriage ended a year later The truth is I＇m against it Usually the women come from poor countries and don＇t know what they＇re getting into My uncle＇s wife had a really hard time adjusting and went back to her country as soon as they split up
I think mail order is out Any other suggestions
I find that meeting people through classes or extracurricular activities is a good idea said Michelle For instance I signed up for a Japanese cooking class both because I like Japanese food and because I thought I might meet someone nice with similar interests
And did you
Yeah I made lots of friends Sumi Katrina Mariahno guys though The class was 90 women In fact now that you mention it the same thing happened with the salsa class the pottery class and my Tai Chi class I met a lot of nice women but I definitely did not find the man of my dreams
Last I interviewed a couple in the library
Friends they said We met through friends It＇s the best way to find the perfect mate
Really I said And why is that
Well your friends usually know what you like And also you know the person is someone you can trust not like meeting someone in a bar or a supermarket For instance we met because Chris＇s lab partner thought we would really get along
Yeah Scott and I met and I immediately liked him I emailed him and it took him three months to email me back
Well I＇m a little shy but it eventually worked Here we are a year later and still together
Well that＇s the best story I＇ve heard yet I said But if I＇ve learned one thing in this study it＇s that meeting someone special no matter how you do it is difficult

题目1
Competition in Olympic sports is supposed to be fair However in judged sports fairness is impossible Therefore judged sports should be banned from the Olympic games A judged sport is any sport that requires judges to determine a winner For example gymnastics figure skating half pipe (snowboarding) and diving are all judged sports
1The writer believes judged sports should be eliminated from the Olympics
选择项：
A T
题目2
Why do I believe that judged sports should be eliminated from the Olympics First of all judges don’t see everything For example a mistake in figure skating can happen in a fraction of a second If a judge blinks or looks away for a moment he or she might miss the mistake and give the skater a higher score than the skater deserves
2One reason that judged sports should not be allowed in the Olympics is that judges can have different opinions
选择项：
B F
题目3
Second two judges can disagree about which athlete gave the best performance In sports in which the difference between gold and silver is usually a few hundredths of a point this kind of subjectivity is unacceptable Can anyone really say with certainty that a gymnast who receives a score of 9825 is a better gymnast than one who scores 9823
3One argument against banning judged sports from the Olympics is that people should stop arguing about it
选择项：
B F
题目4
A lot of people claim that judged sports are subjective and should not be allowed in the Olympics They feel that only sports that are measured objectively for things like speed such as swimming track and skiing should be allowed because judges can’t be objective and fair I disagree with these people Why I believe that no sport is 100 fair and objective
4 The writer here believes all sports are objective

Experiencing Culture Shock
A When Eliza James arrived at the University of Xian she was excited to live in a new country to improve her Chinese and to experience a culture so different from her own But soon her excitement turned to frustration as she encountered one roadblock after another I felt like I couldn＇t accomplish anything My dorm room had no heat I couldn＇t get into the classes I wanted and every time I asked someone for help they gave me the runaround I felt like no one was listening to me Eliza met with administrators sent letters of complaint and even contacted the consulate in Beijing but she got nowhere What Eliza didn＇t realize was that her American approach to solving problems was very different from the Chinese one in which patience and negotiation skills are key She soon learned how to solve problems within the cultural norms of Chinese society instead of forcing her own values onto those around her I finally feel like I fit in and that I know what I＇m doing In fact it＇s really fun being in a place that＇s so incredibly different from what I am accustomed to
B Yoshi Yamamoto is a junior at a small college outside of Boston Although he is an honors student now Yoshi didn＇t always have such an easy time studying in America Teaching methods are very different here than they are in Japan It took me a long time to get used to learning in seminars and discussing ideas with my classmates At first it seemed like I wasn＇t actually learning anything Yoshi＇s reaction was to totally withdraw he didn＇t participate in class discussion he spent lots of time alone in his room and he even skipped class on occasion I thought I could teach myself Now I recognize the value of the US academic system and I am able to adapt it to my own learning style
C Both Eliza and Yoshi experienced what is called culture shock psychological disorientation due to living in a new culture For many international students studying abroad can offer exposure to new cultures and an opportunity to study new fields and languages However it also offers the greater challenge of trying to function in a foreign culture Studying and reading about a certain culture is poor preparation for the reality of living in it According to psychological studies the four stages of culture shock are 1 euphoria 2 hostility 3 gradual adjustment and 4 adaptation Culture shock can be manifested in many ways homesickness boredom stereotyping of or hostility towards the host culture overeating or overdrinking withdrawal and inability to work effectively
D Different people experience different levels of culture shock and react in different ways For example Eliza got angry while Yoshi withdrew from society The most important thing to remember is that culture shock is normal it is not something to be ashamed of Luckily there are some things international students can do to make their adjustment to a new country go more smoothly For instance they can stay in touch with family and friends from home join international student organizations meet people from their own countries and get involved in campus activities Most importantly they can adjust to life abroad by keeping a sense of humor and trying to remain positive

Seasonal Affective Disorder More than Just the Blues
A Joshua dreads the winter months not only because of the cold New England weatherthe sleet snow wind and rainbut because as the seasons change from summer to fall to winter the days get shorter As the days get shorter he starts feeling depressed and irritable and spends more and more time at home eating and sleeping A graduate student in philosophy Joshua finds that he gets little work done during the winter months and has trouble paying attention in class and concentrating on his research I soon realized that what I thought was just the ＇winter blues＇ was something more extreme than that Josh visited a doctor who diagnosed him with SAD
B Seasonal Affective Disorder or SAD is a kind of depression that occurs seasonally It is associated with the long hours of darkness and lack of sunlight during the winter months (people with SAD usually feel worse from December through February) Scientists don＇t completely understand the exact causes of SAD but they believe it is related to a biochemical imbalance in the hypothalamus The hypothalamus is the basic part of the brain that controls the body＇s breathing heartbeat metabolism and hormone release The effects of SAD include moodiness irritability low energy increased appetite for carbohydrates (foods such as potatoes rice and bread) difficulty concentrating and the tendency to oversleep
C Although doctors described SAD for the first time in 1984 humans have probably dealt with the disorder for thousands of years It is not a coincidence that many cultures have important celebrations during the short days of the winter months Christmas Hanukkah and Winter Solstice celebrations all occur in December These celebrations involve lighting candles in order to bring light warmth and happiness to an otherwise depressing time of year
D So what can SAD sufferers do to feel better Naturally they need more light For people who have mild cases of SAD exercising in the morning sun could be enough to help them Phototherapy or light therapy is usually prescribed for people who have more serious cases of the disorder In light therapy patients sit in front of a light box a strong artificial light for up to four hours a day Phototherapy is effective in over 80 of SAD cases and patients usually see results within three to four days Although the symptoms of SAD are similar to those of clinical depression traditional antidepressants have not proven useful in treating SAD While psychological counseling cannot treat the symptoms of SAD it is recommended to help SAD sufferers learn to accept and deal with their illness

Chapter 3 Exercise（分值7分）
I Reading Comprehension (5 points)
Read the passages then answer the questions that follow (1 point each )
Fast food can be good food
Many people are too busy to prepare and eat three nutritious meals a dayso they turn to the convenience of fastfood restaurants Many of the items at fastfood restaurants snack bars and food stands are fattening and not very nutritiousBut fast food doesn’t have to be unhealthyyou can eat at fastfood restaurants and still eat well
Pay Attention to Calories and Fat Content
By paying attention to the number of calories and fat that a food item has you can make smarter choicesCalories are units for measuring how much energy a food will producecondsider two fastfood meals A quarterpound hamburger with cheese jumbosize friesand a 16ounce soda have a total of 1535 calories and 76 grams of fat a broiled (cooked under direct heat or over a flame )chicken sandwich a side salad with lowfat dressingand a glass of water at the same fastfood restaurant have only 422 calories and 7 grams of fat but maybe you really want a hamburger and fries wellyou can have a small hamburgera small serving of friesand a glass of waterAt a total of 490 calories and 20 grams of fatthat’s still a much smarter choice than the large burger friesand 20 grams of fat that’s still a much smarter choice than the large burgerfriesand sada
There’s More That You Can Do
There are a few additional things you can do to make sure you eat well in fast food restaurantSFirst of allsay no when the cashier asks you if you want to supersize you meal (order an extra large portion of each item)Second ask for no mayonnaise or sauceor ask for it on the side (in a separate dish)Thirdsubstitute(use something instead of something else)healthy foods for fatty ones For exampleinstead of ordering deepfried tempuraorder fresh vegetablesInstead of ordering a beef burrito with lots of cheese and sour creamorder a vegetable burrito with beans and riceand don’t eat the chipsAnother thing you can do is order a side salad or a vegetable soup and eat it firstThat wayyou will eat some vegetablesand you won’t be able to eat as much of your burger and friesFnallyeat slowly and stop eating when you’re full It sounds simplebut many people keep eating even after they become full

The growing similarities in diet and eating habits around the world are influencing people of various cultures in different ways For example Western foods are 6 damaging health in the industrialized island country of Japan Instead of small meals of seafood rice and vegetables the typical Japanese diet now includes large amounts of meat dairy products and desserts like tiramisu a rich Italian dish full of chocolate cheese and sugar According to Japanese health researchers such 7 changes in eating habits are related to a great increase in health problems such as heart disease strokes cancer and diabetes On the other hand the changing 8 global diet is having the opposite effect on the people in the CzechRepublic The government of this European nation no longer supports meat and dairy products financially so the cost of these foods is going up In contrast fresh fruits and vegetables are becoming more widely 9 available from private markets and stands Cooks are even serving salads to schoolchildren and families are eating healthier homecooked meals For these reasons fewer Czech men are having heart attacks the women are 10 losing a lot of weight and most people are living healthier lives

Complete the following statements by choosing the best from the answers A B C or D (1 point each)
These days it’s getting easier and easier to find your way around Some people have GPS devices in their cars to make sure they don’t get lost GPS stands for Global Positioning System These devices use satellites in space to see where you are and give you directions to where you want to go And if you don’t have a GPS device you can simply go online to get stepbystep directions Websites like MapQuestcom and mappointmsncom can produce a map and directions in just a few seconds But how do they do it
MapQuest® uses data (information) from a few different sources to produce directions and maps Before MapQuest® went online it sold regular paper maps in places like gas stations The website uses the data from those paper maps information from digital mapping companies and government databases At the moment MapQuest® uses more than 30 computers to read all this data and provides users with millions of maps every day
In order to find the best route (way or path) from one place to another MapQuest® first has to look at all possible routes Then MapQuest® looks at each part of each possible route It considers the types of roads on the different routes Are they dirt roads paved roads freeways or city streets It looks at how many turns there are in each route and what kinds of turns they are Are they right turns or left turns It also considers the speed limit on each road and how many intersections there are An intersection is a place where two or more roads cross each other
MapQuest® can also tell you how long your trip will take you It does this by doing some math MapQuest® bases its estimated driving times on the length and speed limit of each part of the route and the amount of time it probably takes to get through each intersection For example it allows more time for a left turn at an intersection than it does for a right turn Someday maybe we will have cars that can just drive us wherever we want to go but for now mapping websites make it a little harder to get lost

The Family of the Future
Many people today would like the traditional twoparent family back—that is to say they want a man and a woman to marry for life they also think the man should sport the family and the woman should stay home with the children However few families now fall into this 6 category In fact if more women decide to have children on their own the singleparent household may become more 7 typical than the traditional family in many countries Also unmarried couples may decided to have more children—or they might take in foster children or adopt And because people are staying single and 8 living longer (often as widows) there may be more oneperson households in the future On the other hand some people 9 believe similar events happen again and again in history If this is true people may go back to the traditional 10 extended or nuclear family of the past Others think the only certainty in history is changing in other words the structure of the future family could begin to change faster and faster—and in more and more ways

Everyone makes mistakes or so the saying goes But have you ever heard about mistakes in Hollywood When most people think of Hollywood they think of blockbusters (very successful movies) highpaid actors glitz and glamour But according to one Website many Hollywood movies are full of mistakes Some are technical errors For instance in a scene of the sciencefiction adventure film The Matrix when the main character steps out of his car the viewer can clearly see the camera crew in the car window In another scene the same character is typing on his computer yet the computer screen is blank Other movie mistakes are historical For example the epic Gladiator an Oscar winner is known for having lots of historical errors Throughout the movie the gladiator Maximus refers to his home in Spain and the other characters call him the Spaniard However in 180 AD when the movie takes place Spain as a country or even as a concept didn＇t exist yet At another point in the movie Maximus says that his homeland of Spain has the best horses But horses weren＇t brought to the Iberian Peninsula until the invasion of the Moors (North Africans) in 711 AD more than 500 years after the movie takes place The historical drama Titanic another Oscar winner also has its share of historical blunders The Titanic sunk in the year 1912 So why is one of the characters wearing a digital watch In fact movie watchers have found over 100 mistakes in The Matrix Gladiator and Titanic Can you think of any errors in your favorite films
B
How susceptible are you to advertising Has a TV commercial or magazine ad ever made you buy the product that was advertised If so perhaps you have been subjected to subliminal advertising Subliminal advertising is a kind of advertising that appeals to the subconscious The word subliminal comes from the Latin sub meaning lower beneath or under and limen meaning threshold (the level at which something begins to happen) Thus subliminal advertising stimulates your brain at a level below conscious perception You cannot see hear or perceive subliminal ads but they may affect you just the same
There are two main types of subliminal ads The first involves flashing messages quickly during a commercial or film The messages appear and disappear so rapidly that the mind cannot process them consciously but it might receive them passively at a subconscious level James Vicary a market researcher first introduced this kind of subliminal advertising in 1957 when he flashed the words Eat Popcorn and Drink CocaCola every five seconds during a movie The messages couldn＇t be seen yet Vicary claimed that the moviegoers＇ brains could perceive them Coke sales went up by 18 and popcorn sales by over 50 More recently the same type of subliminal advertising was used in a negative ad for a political campaign In the ad the word rats flashed up briefly during the part of the ad describing one party＇s healthcare plan The purpose was to associate that opposing party with the negative word rats The second kind of subliminal advertising involves hiding or incorporating images into visual advertisements A wellknown example is on a package of a famous brand of cigarettes Some say that if you look closely you can see the image of a man who is sexually aroused In fact a lot of subliminal advertising involves sex coming from the idea that sex sells One media researcher claims that everything from crackers to alcohol to soda has used subliminal sexual imagery to appeal to buyers
Although studies show that consumers believe strongly in the power of subliminal ads no one can prove the effects of subliminal advertising Psychologists and others who study subliminal stimuli have not been able to show that subliminal advertising actually works Many advertising researchers believe that traditional ads in which a powerful image is used to sell a product are more effective than subliminal advertising All the same it still remains a controversial topic one that is on the mind of buyers and sellers alike

Meeting the Perfect Mate
What is the best way to meet the perfect husband or wife I am continuing to interview students on campus trying to answer this question for my sociology class So far people have mentioned arranged matches discos and bars computer dating services and personal ads One guy even said he thought supermarkets were the best places to meet women I guess you can talk a lot about a head of lettuce
I decided to go to the school cafeteria to interview some people there
I think date cafés are the best way to meet people said my friend Rahul
Date cafés What＇s that I asked
Well a date café is both a café and a dating service You go to the café order a cup of coffee or whatever you want and look through people＇s profiles Then if someone interests you you can send him or her an email and arrange a date at the café You can also fill out your own profile and have people email you The form asks you about everything from looks to interests to religion The date café is a relaxed way to make contacts
Are there many of them around I asked
Hmm Well there＇s one near campus called Drip In fact I had a Drip date just last week said Rahul
Drip But isn＇t that a word that＇s used to describe someone who is dull and boring It doesn＇t sound too promising
Yeah well it＇s funny you say that because my date was pretty uninteresting She barely talked at all and she kept looking down at her coffee mug
Well what about a mail order bride said Rahul＇s roommate Joni
A what I asked
A mail order bride You know you search for your wife in a catalog and the next thing you know you＇re married With the Internet it＇s easier than ever she said
Ugh that sounds awful I said Have you ever met anyone who has done that
Yes my uncle did it His marriage ended a year later The truth is I＇m against it Usually the women come from poor countries and don＇t know what they＇re getting into My uncle＇s wife had a really hard time adjusting and went back to her country as soon as they split up
I think mail order is out Any other suggestions
I find that meeting people through classes or extracurricular activities is a good idea said Michelle For instance I signed up for a Japanese cooking class both because I like Japanese food and because I thought I might meet someone nice with similar interests
And did you
Yeah I made lots of friends Sumi Katrina Mariahno guys though The class was 90 women In fact now that you mention it the same thing happened with the salsa class the pottery class and my Tai Chi class I met a lot of nice women but I definitely did not find the man of my dreams
Last I interviewed a couple in the library
Friends they said We met through friends It＇s the best way to find the perfect mate
Really I said And why is that
Well your friends usually know what you like And also you know the person is someone you can trust not like meeting someone in a bar or a supermarket For instance we met because Chris＇s lab partner thought we would really get along
Yeah Scott and I met and I immediately liked him I emailed him and it took him three months to email me back
Well I＇m a little shy but it eventually worked Here we are a year later and still together
Well that＇s the best story I＇ve heard yet I said But if I＇ve learned one thing in this study it＇s that meeting someone special no matter how you do it is difficult

Competition in Olympic sports is supposed to be fair However in judged sports fairness is impossible Therefore judged sports should be banned from the Olympic games A judged sport is any sport that requires judges to determine a winner For example gymnastics figure skating half pipe (snowboarding) and diving are all judged sports
1The writer believes judged sports should be eliminated from the Olympics
选择项：
A T
题目2
Why do I believe that judged sports should be eliminated from the Olympics First of all judges don’t see everything For example a mistake in figure skating can happen in a fraction of a second If a judge blinks or looks away for a moment he or she might miss the mistake and give the skater a higher score than the skater deserves
2One reason that judged sports should not be allowed in the Olympics is that judges can have different opinions
选择项：
B F
题目3
Second two judges can disagree about which athlete gave the best performance In sports in which the difference between gold and silver is usually a few hundredths of a point this kind of subjectivity is unacceptable Can anyone really say with certainty that a gymnast who receives a score of 9825 is a better gymnast than one who scores 9823
3One argument against banning judged sports from the Olympics is that people should stop arguing about it
选择项：
B F
题目4
A lot of people claim that judged sports are subjective and should not be allowed in the Olympics They feel that only sports that are measured objectively for things like speed such as swimming track and skiing should be allowed because judges can’t be objective and fair I disagree with these people Why I believe that no sport is 100 fair and objective
