In many parts of the world cars play an essential role in daily life and many societies would stop to function without them. So the claim that in 20 years’ time no one will own cars may be hard to believe. But this is the prediction made by a team of transport researchers who are taken seriously not only by governments but also by car manufacturers.

The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an international research program. The team there believes that by 2020 all cars will be computerized, which will mean extremely large fuel savings, no accidents and better use of roads. The super-intelligent car of the 21st century will drive itself and it will not be owned by on individual. Instead, we will have a choice of cars and change them as frequently as we change our clothing.

According to Dr. David Davis, who leads the research team, these predictions are based on the rising cost of the car culture ,which had blocked up our cities, polluted our air and caused more deaths than both world wars put together.

Davis says cars will be fitted with intelligent cruise control devices to regulate the distance between one car and another. Brakes and accelerators (加速器) will become redundant（多余的） because the car will automatically speed up or slow down to match the speed of the car in front. Computers are much safer drivers than people, so cars in a road train will be able to drive much closer together than cars driven by people.

By 2010 Dr. David Davis believes car technology will give motorists a clear view of the road whatever the weather conditions by projecting an image of the road ahead onto the car’s windscreen. And by 2020 cars will travel in convoy linked to each other electronically. Cars will be connected by an electronic tow(牵引) bar to the car in front to form “road-trains”. “The front vehicle in such a train burns the ordinary fuel” says Davis. “But all the others in the train would burn about ten percent of the normal amount and so produce about ten percent of the pollution.

We know from the passage that governments and car manufactures ________.

   A. don’t believe the prediction that no one will own cars by 2020.

   B. are devoted to the technological innovation (创新) in car industry.

   C. consider the predictions made by the researchers seriously.

   D. have put the super-intelligent car into mass production.

Which of the following will NOT be the characteristics of the cars of 2020 ?

   A. There will be no brake and accelerator in cars.

   B. We will own as many cars as we want .

   C. All cars will be driven by computers.

   D. Car accident will no longer happen.

The expression closest in meaning to the underlined phrase “ in convoy”(Para 5) is ______.

   A. in line B. sidelong C. side by side D. next to one another

What will happen if cars are linked to each other electronically in 2020 ?

   A. Motorists will get a clear view of the road.

   B. The weather conditions won’t have effect on motorists.

   C. There will be a decrease in the pollution caused by car .

   D.All trains will burn less fuel than present.

Do you find getting up in the morning so difficult that it’s painful? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.

During the hours when you labor through your work you may say that you’re “hot”, that’s true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak(最高峰). For some people the peak comes during the forenoon. For others it comes in the afternoon or evening. No one has discovered why it is so, but it leads to such familiar monologues(自言自语)as: “Get up, John! You’ll be late for work again!” the possible explanation to the trouble is that John is at his temperature—and—energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has.

You can’t change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes. Maybe you’re sleepy in the evening but feel you must stay up late anyway. Counteract(对抗)your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour. This won’t change your cycle, but you’ll get up steam and work better at your low point.

Get off to a slow start which saves your energy. Get up with a leisurely yawn(呵欠)and stretch. Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.

If a person finds getting up early a problem, most probably ______.

       A．he is a lazy person       

       B．he refuses to follow his own energy cycle

       C．he is not sure when his energy is low

       D he is at his peak in the afternoon or evening

Which of the following may lead to family quarrels according to the passage?

       A．Not knowing about the energy cycle   

       B．Familiar monologues

       C．A change in a family member’s energy cycle

       D．Attempts to control the energy cycle of other family members

If one wants to work more efficiently at his low point in the morning, he should ______.

       A．change his energy cycle B．overcome his laziness

       C．get up earlier than usual        D．go to bed earlier

You are advised to rise with a yawn and stretch because it will ______.

       A．help to keep your energy for the day’s work

       B．help you to control your temper early in the day

       C．enable you to concentrate on your routine work

       D．keep your energy cycle under control all day

It was reported last week that developers could take photos from Apple mobile and Google Android devices without the phone owners knowing that the images were being taken. In Apple’s case, developers can also obtain the location information for each photo.

Senator(参议员) Charles Schumer said in a telephone interview that his office had spoken with officials at both Apple and Google on Monday.

“We asked them if they could find a way on their own to prevent Apple from having access to private information,” Mr. Schumer said. “They were friendly and open to the idea that this ought to be changed.”

On Sunday, Mr. Schumer said that he planned to send a letter to the Federal Trade Commission asking the agency to investigate Apple and Google after the privacy concerns came to light. Claudia Bourne Farrell, an F.T.C. spokeswoman, said the agency had received the letter but she could not comment further.

“It worries people to think that one’s personal photos, address book, and who knows what else can be obtained and even posted online without permission,” Mr. Schumer wrote in his letter to the F.T.C. “If the technology exists to open the door to this kind of privacy invasion, then surely technology exists to close it, and that’s exactly what must happen.”

Mr. Schumer said if Apple and Google could not come to an agreement to fix the problem, then he would be forced to take the issue further.

He said other companies had been willing to work with his office to fix issues. “I’m optimistic that we can get this changed without any regulation,” he said. “If it’s not changed, then we’ll turn to the F.T.C., and if that doesn’t work then we’ll consider legislative approach.”

The F.T.C. has warned companies to try to be more vigilant(警醒的) in their efforts to protect consumers when it comes to privacy.

1.The senators spoke with officials at both Apple and Google___________.

A. to urge them not to invade consumers’ privacy

B. to discuss whether it is illegal to have access to private information

C. to stop them from developing the technology of taking photos

D. to keep them from obtaining the location information for each photo

A. Privacy invasion from Apple has existed for a long time.

B. Mr. Schumer takes the privacy concerns caused by Apple and Google seriously.

C. Privacy invasion from Google has existed for a long time.

A boy was walking home from school when he saw a large, tempting（诱人的）apple on one of the branches of an apple tree hanging out over a tall fence. The boy wasn’t much of a fruit-eater,  26  a bar of chocolate if given the choice,  27   , as they say, the forbidden fruit can be tempting. Seeing the apple, the boy wanted it. The more he looked at it, the 28  he felt and the more he wanted that apple.

He stood on tiptoe(脚尖)，29  as high as he could, but even as his tallest 30  he was unable to touch it. He began to  31  up and down, as high as he could, at the  32  of each jump stretching his arms to get the apple. Still it remained out of  33 .

Not giving up, he thought, if only he had something to  34  on. His school bag wouldn’t give enough height and he didn’t want to  35  the things inside, like his lunch box, pencil case, and Gameboy.

He started to say to himself, “ This isn’t  43 , I don’t have the apple and I’m feeling miserable as well. There’s  44  more I can do to get the apple—hat is unchangeable—but we are supposed to be able to  45  our feelings. If that’s the case, what can I do to feel better?
