   Self-driving cars are so popular that the University of Michigan has even established a town called Mcity to allow car manufacturers to safely test their autonomous cars.

While Mcity can be used to simulate(模拟)many real-life road conditions,it can't help test gestures drivers use to communicate their intention(意图)to other drivers,pedestrians or cyclists. To find a solution,US car manufacturer Ford,with researchers from Virginia Tech,at the beginning considered using text as a way to communicate the car's intention,but decided it would probably not work universally. The option of using symbols was also rejected,because research shows that a majority of people do not have a good understanding of what they mean.

Finally, the researchers settled on light signals. A white light warned that there were no humans in the car. A slow blinking one indicated that the car was coming to a stop, while a rapidly flashing light cautioned passersby that the car was about to speed up.

Then came the big challenge—testing the signals on real roads. "We needed to try out this new lighting to communicate the intention of the vehicle, but if you've got a driver behind the seat, you still have natural communication between humans," said Andy Shaudt, who led the research team. "So we needed to make it look like a driverless car."

The team designed a car seat costume(戏装)that the driver would wear to cover his or her face and upper body. Of course,the drivers could see very clearly. The researchers then equipped the car with cameras to capture human reactions to a light bar,which flashed one of the three signals when appropriate. Six drivers,all keeping their hands low on the wheel so as not to be noticed,took turns to test driving the car through the busy streets.

The overall reaction to the flashing lights was very encouraging. Who knew costumes could be useful for more than Halloween?

【小题1】What did the team first consider using as a way to communicate the car's intention?
A.Light.B.Language.
C.Symbols.D.Sound.
【小题2】The underlined word "they" in the second paragraph refers to ________.
A.symbolsB.drivers
C.researchersD.flashes
【小题3】What does a rapidly flashing light mean?
A.The car was coming to a stop.
B.There was no driver in the car.
C.The car was about to speed up.
D.The car was about to slow down.
【小题4】The car seat costume was intended to ________.
A.amuse the driverB.attract the pedestrians
C.warn the cyclistsD.confuse the people

   A start-up company in California, called Zume, is testing machines that make pizza. The robot takes and shapes dough to create the base of the pizza. It then adds tomato sauce, cheese, meat or other toppings. Next, the robot places the uncooked pizza into a hot oven. A few minutes later, the pizza is ready. The pizza comes out the same each time. Zume says the robots work quickly and do not get sick. The robots do not get paid either.

Julia Collins is the company’s founder and chief executive officer (CEO) . Her business can spend money on better food products because it does not have to pay the robots. Zume is using robots to make pizza.

Charity Suzuki has bought the robot-made pizza. She likes its taste. “It’s delicious. It’s always hot and fresh when it comes. I mean it’s great that they’re making it, but I can’t tell the difference that it’s made by a robot versus a human.”

Other companies say they are developing robots so people can get higher quality food faster. But what about the jobs the robots are taking from humans?

Ken Goldberg is a professor at the University of California in Berkeley. He also directs the school’s automation laboratory. Goldberg says researchers have been working with robots for 50 years. He says that, while there has been progress, the jobs are not going to disappear right away. “I want to reassure (使放心) restaurant workers that the skills that they have are still going to be of value,” Goldberg said.

“We’re going to get rid of boring, repetitive, dangerous jobs and we’re going to free up people to do things that have higher value. There’s going to be amazing new ways of working that don’t exist yet but are going to be created.”

【小题1】Why can Zume devote more money to better food products?
A.It earns a lot by selling pizza.B.It wants to create more robots.
C.It can save a lot by using robots.D.It hopes to attract more customers.
【小题2】What can we know about the robot-made pizza according to Suzuki?
A.It really agrees with her.B.It is hot and fresh all the time.
C.It is tastier than the man-made.D.It is delicious and free of charge.
【小题3】What’s the benefit of robots’ making pizza?
A.They work efficiently.B.They help sick people.
C.They need few payments.D.They produce more food.
【小题4】What does Goldberg think of the jobs of restaurant workers?
A.Interesting.B.Boring.
C.Dangerous.D.Necessary.

   A new tool of communication called the "drift diary" is doing the rounds among young college graduates.

The "drift diary", like those ancient paper messages put into a bottle left to drift on the high seas to reach hundreds of miles away, connects lonely hearts. It was first started by a Beijing woman, who goes by the screen name Little S, in 2007.It has become the preferred tool of communication among youngsters afraid to reveal their innermost self to peers, but wanting to share their lives with others. The way it works is that the initiator(发起人)of the diary mentions it on popular Internet forums such as Tianya and Douban. Those wanting to react or otherwise add to the diary then send their real names and addresses to the initiator via e-mails or text messages.

The numbers in one group are usually restricted to between 30 and 50. The diary then is passed on to another by the express delivery or personal handover. The diary writers are mostly anonymous(匿名的)but if they wish to reveal their identity they can do so by posting their contact information at the end of their postings.

The diary writers not just add words but also decorate the plain notebooks with cartoons, drawings or even dress it up with a ribbon or a new cover. Interesting experiences, travel journals, the simple joys of everyday living or sweet recollections of childhood, all find a place in these diaries. Most often, though, the writers set down their frustrations and predicaments.

It usually takes one year for a diary to return to the initiator. The last recorder is the luckiest one, with access to all previous entries, while others can request photocopies of them from the diary's initiator.

【小题1】Why is the "drift diary" popular among youngsters?
A.Because they hate using the Internet.
B.Because they like to show themselves to peers.
C.Because they want to share their lives with strangers.
D.Because they find it fashionable to be a diary writer.
【小题2】Which one shows the correct way a drift diary works?
①The diary then is passed on between the recorders.
②The diary returns to the initiator.
③The initiator of the diary makes a mention online.
④Participants request photocopies of the diary from the diary's initiator.
⑤Those who want to participate in the program get in touch with the initiator.
A.③⑤①④②B.③⑤①②④
C.④⑤①②③D.①③⑤②④.
【小题3】What does the underlined word "predicaments" in the last but one paragraph probably mean?
A.Successful experiences.B.Sense of achievement.
C.Difficult situations.D.Favorable conditions.
【小题4】Which of the following can be used as the best title for the passage?
A.Drift Diary——A New Tool of Communication
B.How a Drift Diary Works
C.Share Your Lives with Strangers
D.The Diary Passed on
