  What comes into your mind when you think about robots? Do you imagine armies of evil metal monsters planning to take over the world? Or, perhaps of mechanical men who have been created as guards or soldiers by a mad genius? Or maybe you think of man- like robots who act, think, and look like human beings. In fact robots like these have more to do with science fiction films than with real life. In the real world robots are machines that do jobs which otherwise have to be done by people. Robots either operate by themselves or under the control of a person.
  In a car factory, for example, robot machinery can put together and paint car bodies. On the sea bed remotecontrolled(遥控)underwater machines with mechanical arms can perform tasks too difficult for divers. Robot spacecraft can explore the solar system and send back information about planets and stars.
  Many robots have computer brains. Some robots are fitted with cameras , sensors, and microphones which enable them to see, to feel, and to hear. And some robots can even produce electronic speech.
  All this does not mean that a robot can think and behave like a human being. Present day robots have to be programmed with a good deal of information before they can carry out even simple tasks.
 44.Robots in real life________.
  A. can behave like human beings   B. have the ability to control the world
  C. can think by themselves        D. can help us with a lot of work
 45.According to this article, which of the following is not true about robots in the real world?
  A. Some robots are as creative as artists.     B. Some robots can help manufacture cars.
  C. Some robots can see and hear.       D. Some robots can explore outer space.
 46.Robots can perform many tasks for man because________.
  A. they have intelligence    B. they are supplied with computer programs
  C. they can imitate human beings    D. they have the ability to learn new things
 47.The robots in science fiction films and those in real life differ mainly in________.
  A. mentality   B. appearance   C. material    D. size

第三部分:阅读理解(共15小题;每小题2分,满分30分)
请认真阅读下列短文,从短文后各题所给的A、B、C、D四个选项中,选出最佳选项,并在答题卡上将该项涂黑。
If you see a student napping (打瞌睡) in the library, don"t roll your eyes. New research from the University of California, Berkeley, shows that an hour"s nap can considerably improve and restore your brain power. Indeed, the findings suggest that a nap not only refreshes the mind, but can make you smarter.
"Sleep not only rights the wrong of extended wakefulness but it moves you beyond where you were before you took a nap." said Matthew Walker, an assistant professor of psychology at UC Berkeley and the lead investigator of UC Berkeley sleep studies.
The latest study suggests that the brain may need sleep to process short-term memories, creating "space" for new facts to be learned. In their experiment, 39 healthy adults were given a hard learning task in the morning~~with broadly similar results, before half of them were sent for their nap. When the tests were repeated, the nappers improved their scores by 10 percent on average after sleeping; the scores of those who didn"t nap actually dropped by 10 percent.
The results support previous data from the same research team that staying up all night―a common practice at college during midterms and finals―decreases the ability to memorize new facts by nearly 40 percent, due to a shutdown of brain regions for lack of sleep, said Walker.
"Sleep is needed to clear the brain"s short-term memory storage and make room for new information." said Walker. "It"s as though the e-mail inbox in your brain is full and, until you sleep and clear out those e-mails, you"re not going to receive any more mail."
However, Professor Derk Jan Dijk, the director of the Surrey Sleep Research Centre, said that there was no clear evidence that daytime napping offered a distinct advantage over sleeping soundly just once over 24 hours.
"The sleep-wake cycle is not as fixed as we might think―we have the capability to sleep in different ways, "said Professor Derk Jan Djjk.
"The size of these effects is much more difficult to judge―if I have to learn something, for example, it"s easier to do this when I"m feeling awake and ready than when I"m sleepy." he added.
56.According to UC Berkeley"s new findings, the benefit of a nap is that   .
A.it helps to fix a napper"s sleep-wake cycle
B.it makes hard learning tasks not difficult any more
C.it allows the brain to make room for new learning
D.it gives nappers chances to clear out their memory storage
57.Matthew Walker"s study shows that___________.
A.learning ability in the morning is usually higher than that in the afternoon
B.extra working hours before an exam can make up for the lack of daily efforts
C.the size of the effects of napping depends on when it is taken
D.staying up late before an exam does not necessarily improve students" exam performance
58.The two research teams mentioned in the text may both agree that_____________      .
A.people"s sleep-wake cycle decides the length of midday nap
B.sufficient sleep betters people"s learning performance
C.scientific experiments are undependable as the results are often hard to judge
D.the differences in their findings result from different methods applied
59.What can we learn from this passage?
A.Rolling your eyes can stop you from napping.
B.Some people might move themselves when sleeping.
C.College students tend to study late into night before important exams.
D.Sleeping once over 24 hours is much better than daytime napping.

For some time past it has been widely accepted that babies----and other creatures----learn to do things because certain acts lead to “rewards”; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological (生理的) “drive” as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise.
It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.
Paousek began his studies by using milk in the normal way to “reward” the babies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children’s response in situation where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement “switched on a display of lights---- and indeed that they were able to learn quite complicated turns to bring about this result, for instance, two left or two right, or even to make as many as three turns to one side.
Papousek’s light display was placed directly in front of the babies and he made the interesting observation that sometimes they would turn back to watch the lights closely although they would “smile and bubble” when the display came on. Papousek concluded that it was not primarily the sight of lights which pleased them, it was the success that they were achieving in solving the problem, in mastering the skill, and that there exists a primary human urge to make sense of the world and bring it under intentional control.
72.According to the author, babies learn to do things which ____.
A. are directly related to pleasure          B. will meet their physical needs
C. will bring them a feeling of success          D. will satisfy their curiosity
73.Papousek noticed in the studies that a baby ____.
A. would make learned response when it saw the milk
B. would carry out learned movements when it had enough to drink
C. would continue the simple movements without being given milk
D. would turn its head to right or life when it had enough to drink
74.In Papousek’s experiment babies make learned movements of the head in order to ____.
A. have the lights turned on              B. be rewarded with milk
C. please their parents                   D. be praised
75.According to Papousek, the pleasure babies get in achieving is a reflection of ____.
A. a basic human desire to understand and control the world
B. the satisfaction of certain physiological needs
C. their strong desire to solve complex problem
D. an important human urge to display their learned skills
