   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．symbols	B．drivers
C．researchers	D．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 driver	B．attract the pedestrians
C．warn the cyclists	D．confuse the people

What will cars be like in the future? Maybe we can sit in a car that can drive all by 【小题1】（it） in a few years’ time. In fact, with the rapid development of modern science and technology, the self-driving car is becoming a 【小题2】（real） on busy streets.

According to a report by Google, the world-famous search engine, its self-driving cars 【小题3】（travel） more than 700,000 miles on roads in California so far. The first self-driving car 【小题4】（make） by Google came out in 2009. There are cameras on the top of the car, 【小题5】 allow the computer in the car to draw a 3-D map of the surroundings. In addition, Google says that its self-driving cars can discover hundreds of separate 【小题6】（object）at the same time, which might be an improvement on the human driver experience. As 【小题7】 result, there will be far 【小题8】（few） traffic accidents caused by careless driving.

However, self-driving cars are much too 【小题9】（expense） right now. Scientists across the world are doing their best to bring down the costs, 【小题10】 hundreds of thousands of dollars to the cost that most people can afford.
