Have you ever seen a car without a driver It sounds crazy but these computerdriven driverless cars will soon be filling roads near you Companies like Google and Tesla have been designing and testing these cars and the technology is there
So how The cars have sensors(感应器)all around which can find other cars and objects in the road Road signs are read by cameras and satellite navigation systems(卫星导航系统)are used so the car knows how to get where you want to go All you have to do is type in the address Finally a central computer system takes in all the information that it receives from the sensors and cameras and works out when to speed up stop and turn
Sound like your idea of heaven(天堂) Sitting back looking out of the windows and even watching a film or reading a book while driving’ would be possible with this new technology You wouldn’t have to worry about remembering directions to where you’re going In addition computers would also drive more safely than people — they would obey the rules and have quicker action times when in dangerous situations
However there are many drawbacks of driverless cars Computers would have difficulties making ethical(道德)decisions if a child ran into the road would the computer choose to hit the child or turn suddenly and potentially kill the car’s passengers Moreover I personally find driving fun –I’d miss never driving a car myself There would also be many other decisions to be made –should children or drunk people be allowed in a driverless car by themselves Or would there need to be a person with a driving license in the car at all times
I’m not certain I’d want a driverless car – but it’s only a matter of time before they’ll become more affordable and popular on our roads
1 When using a driverless car you need only
A read the road signs carefully B check the cameras
C put the address into the computer D remember the directions
2 The third paragraph mainly tells us about the of driverless cars
A instructions B standards C advantages D tests
3 The underlined word potentially in Paragraph 4 means
A possibly B successfully C especially D naturally
4 What’s the writer’s opinion about future driverless cars
A They’ll cause more accidents B They’ll be less expensive
C They’ll use less energy D They’ll run much faster

When the Audet family turns on the lights at Blue Farm they are using electricity that comes from cows—cow manure(粪肥) to be specific
Cows produce a lot of wastes One cow can create 30 gallons of wastes each day Now imagine the output of over 1000 cows at Blue Farm That’s really a big amount
When farmers clean their barns they put the wastes in a big heap and spread some of them on their fields for fertilizer(肥料) But now places like Blue Spruce Farm have a new way of using cow wastes They use them to produce electricity

The machine pushes the manure into a big 600gallon tank like a small swimming pool The tank is called a digester(化粪池) because what happens there is just like what happens inside a cow Bacteria(细菌) get to work and continue to digest the manure
Methane gas(甲烷沼气)in the atmosphere is known as a greenhouse gas because it keeps heat just like a greenhouse does causing our planet to warm up That’s an environmental concern But the digester has a good result Its gas is kept and used to power electric generators(发电机).
