People in several American states may be surprised to see cars on city streets without a driver.Experimental driverless vehicles now are legal in Florida,Nevada and California.They are pointing the way to a future that is not far down the road.The high-tech company Google has a number of self-driving cars,which had covered 480,000 kilometers by August.Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.
In September,California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state."Today we're looking at science fiction becoming tomorrow's reality—the driverless car."The technology for these cars includes cameras,radar and motion sensors.The systems have been improved through competitions sponsored by the U.S.government agency DARPA.Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.
Cars have become much more fuel-efficient,and new electronic features are making Hondas safer,said Angie Nucci of Honda America."A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes." Other safety features include warning systems on the front and the sides of the cars.These systems help drivers,but don't replace them.Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer.
"By taking out drivers,you also remove most risks of an accident," Kendall said.He said consumers,however,may be unwilling to lose control."It may take them time to come to realize that the technology is indeed reliable,but it will have to prove itself first."
Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable.He said this will happen as the technology is improved.
What can we learn from Paragraph l?
A.Driverless vehicles are now legal in the whole USA.

第三部分:阅读理解(共20小题;每小题2分, 满分40分)
阅读下列短文,从每篇短文后所给各题的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该项涂黑。
My grandfather came from Hungary and was the only one in his family who settled down in the United States. The rest of his family remained in Europe. When World War I broke out, he seemed to have become another man, downhearted. Such obvious change was not born out of his welfare, but out of fear: if his only son, my uncle, had to go to war, it would be cousin fighting against cousin.
One day in 1918, my Uncle Milton received his draft notice. My grandparents were very upset. But my mother, at the age of 10, felt on top of the world about her soldier brother going off to war. Realizing how he was regarded by his little sister and all of her friends, my uncle brought them all service pins, which meant that they had a loved one in the service. All the little girls were delighted.
The moment came when my uncle and the other soldiers, without any training but all in uniforms, boarded the train. The band played and the crowd cheered. Although no one noticed, I’m sure my grandmother had a tear in her eye for the only son. The train slowly pulled out, but not about a thousand yards when it suddenly paused. Everyone stared in wonder as the train slowly returned to the station. There was a dead silence before the doors opened and the men started to step out. Someone shouted,”The war is over. ”For a moment, nobody moved, but then the people heard someone bark orders at the soldiers. The men lined up in two lines, walked down the steps, and with the band playing, marched down the street, as returning heroes, to be welcomed home. My mother said it was great day, but she was just a little disappointed that it didn’t last a tiny bit longer.
56. What the grandfather was most worried about was .
A. the spread of the world war B. the safety of his living two cousins
C. a drop in his living standards D. his relatives killing each other
57. The underlined phrase “draft notice” means “ “
A. order for army service B. train ticket for Europe
C. letter of rejection D. note of warning
58. What did the “service pins”(in Para. 2)stand for in the eyes of the little girls?
A. Strength. B. Courage. C. Victory. D. Honor.
59. Which of the following words can best describe the ending of the story?
A. Disappointing. B. Unexpected. C. Uncertain. D. Inspiring.

Advice to “sleep on it” could be well founded, scientists say. After a good night’s sleep, a problem, which couldn’t be solved the night before, can often seem more manageable, although the evidence until now has been anecdotal (个人体验的). But researchers, at the University of Luebek in Germany, have designed an experiment that shows a good night’s sleep can improve insight (顿悟) and problem-solving.
“If you have some newly-got memories in your brain, sleep acts on these memories and restructures (重新组织) them, and as a result, after sleep, the insight into problem which you could not solve before increases,” said Dr Jan Born, a neuroscientist (神经科学家), at the university.
To test the theory, they taught volunteers two simple rules to help them turn a string of (一连串) numbers into a new order. There was also a third, hidden rule, which could help them increase their speed in solving the problem. The researchers divided the volunteers into two groups: Half were allowed to sleep after the training, while the rest were forced to stay awake. Dr Jan Born and his team noticed that the group that had slept after the training were twice as likely to figure out (想出) the third rule as the other group.
“Sleep helped,” Born said in a telephone interview. “The important thing is that you have to have a memory representation (描绘,表现) of the problem you want to solve in your brain and then you sleep, so it can act on the problem.” But Born admitted that he and his team don’t know how restructuring of memories occurs or what governs it.
Pierre Maquet and Perrine Ruby of the University of Liege in Belgium said the experimental evidence supports the anecdotal suggestions that sleep can help develop creative thinking. Although the role of sleep in human creativity will still be a mystery, the research gives people good reason to fully respect their periods of sleep, they added.
57. The underlined phrase “sleep on it” in Paragraph 1 probably means ______.
A. to delay deciding something until the next day
B. to get as much sleep as possible
C. to go on sleeping without being disturbed
D. to sleep till after the time you usually get up in the morning

A. people should sleep so long as they have time

C. people have various periods of sleep
D. people know how sleep reconstructs memories
60. What would be the best title for the passage?
A. How Sleep Works B. Sleep Helps Solve Problems
C. No Evidence, But Well Founded D. Born’s Discovery On Sleep

A gadget (器具) which makes water out of air could become the greatest household invention since the microwave.
Using the same technology as a dehumidifier (除湿器), the Water Mill is able to create a ready supply of drinking water because it can always get it from an unlimited source—the air.
The company behind the machine says not only does it offer an alternative to bottled water in developed countries, but it is a solution for the millions who face a daily water shortage.
The machine works by drawing in wet air through a filter (过滤器) and over a cooling instrument which changes it into water drops. It can produce up to 12 liters a day. The Water Mill will also produce more water when storms pass over, as the amount of water which is contained in the air increases. In keeping with its eco-development, the machine uses the same amount of electricity as three lights.
Inventor Jonathan Ritchey said: “The demand for water is off the chart. So people are looking for freedom from water distribution systems that are shaky and unreliable.”
The machine, which is about 3 feet wide, is likely to cost £800 when it goes on sale here in the spring. Its maker, Canadian Firm Element Four, roughly (粗略地) calculates that a litre of water cost around 20p to produce.
Environmentalists state that half the world’s population will face water shortage because of climate change by 2080. One in five is said to lack access to safe drinking.
The Water Mill is not effective in areas where the amount of water contained in the air is below about 30 percent, but in Britain that won’t be much of a problem.
49. What does the underlined word “it” refer to?
A. Drinking water. B. Invention. C. Microwave. D. Water Mill.
50. What do we learn about the machine?
A. It works in the same way as microwaves.
B. It is very expensive for families to afford.
C. It absorbs steam and turns it into water.
D. It helps to make the water clean to drink.
51. What does the passage lead us to believe?
A. The cost of water will go up. B. Bottled water will disappear sooner.
C. The machine is energy saving. D. The machine will be popular worldwide.
52. What’s the best title for the passage?
A. A New Way to Solve Water Problem. B. A Machine to Make Water out of Air.
C. A Dehumidifier to Produce Water. D. An Absolutely New Invention
