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

Whether we find a joke funny or not largely depends on where we have been brought up.The sense of humour is mysteriously(神秘地)connected with national characteristics.A Frenchman ,for instance, might find it hard to laugh at Russian joke.In the same way, a Russian might fail to see anything amusing in a joke which would make an Englishman laugh to tears.
Most funny stories are based on comic situations.In spite of national differences, certain funny situations have a worldwide request.No matter where you live, you would find it difficult not to laugh at, say ,Charlie Chaplin’s early films.However, a new type of humour, which stems largely from America, has recently come into fashion.It is called “sick humour”.Comedians base their jokes on tragic situations like violent (cause by force)death or serious accidents.Many people find this sort of joke distasteful.The following example of “sick humour” will enable you to judge for yourself.
A man who had broken his right leg was taken to hospital a few weeks before Christmas.From the moment he arrived there, he kept on pestering(糾纏) his doctor tell him when he would be able to go home.He was afraid of having to spend Christmas in hospital .Though the doctor did his best, the patient’s recovery was slow.On Christmas day, however, the doctor consoled(安慰)him by telling him that his chances of being able to leave hospital in time for New Year celebrations were good.The man took heart and, sure enough , on New Year’s Eve he was able to hobble(跛行) along to a party.To compensate(補(bǔ)償)for his unpleasant experiences in hospital , the man drank a little more than what was good for him.In the process, he enjoyed himself and kept telling everybody how much he hated hospitals.He was still mumbling something about hospitals at the end of the party when he slipped on a piece of ice and broke his left leg.

Without the atmosphere there would be no weather, no wind, rain, snow, or clouds. Air is all around us; we live at the bottom of a great ocean of air. It is invisible, but we can feel it when it moves. There are miles of air above us, pressing down with great weight on the earth and everything on it. Because air presses down on us from all directions at the same time, and because we are able to bear (忍受) this weight, we do not seem to feel it. But scientists have proved that air has this weight, and that anything that has weight creates(產(chǎn)生) a force called pressure. As changes in air pressure take place, they, make air move.
Air is a gas that expands(膨脹) when heated, gets lighter, and moves upward. When air is cooled, it gets heavier, sinks close to the earth's surface, and flows like water in a great river. As warn air rises, cold air rushes in to take its place. 'Thus winds originate (起源). The winds that blow high above us are caused by the warmer air running away from colder air. The wind we feel near the earth's surface is the heavy colder air trying hard to catch the warmer air. Changes in temperature cause the air to move. And of course there are many changes, so air movements are taking place practically all the time.
小題1:The first paragraph mainly tells us the causes of
A.why we don't feel airB.why atmosphere is important to us
C.why there is air surrounding usD.why there is air pressure
小題2:Air moves under such conditions that
A.there is air pressureB.the air is heavy
C.a(chǎn)ir pressure doesn't remain the same all the timeD.a(chǎn)ir comes up and down
小題3:Which of the following pictures best tells the movements of warm air and cold air?
小題4:According to the passage, in same areas if farmers who grow grapes (葡萄) light fires in the early morning, that is because the farmers want to________________.
A.drive away warm airB.prevent cold air from coming to harm their plants
C.cause more windD.stop warm air running away

PART FOUR  WRITING
SECTION A(10%)  Directions: Read the following passage.Complete the diagram by using the information from the passage.      Write NO MORE THAN THREE WORDS for each answer.
Internet use appears to cause a decline in psychological well-being, according to research at Carnegie Mellon University.
Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who logged on less frequently, the two-year study showed. And it wasn’t that people who were already feeling bad spent more time on the Internet, but that using the Net actually appeared to cause the bad feelings.
Researchers are puzzled over the results, which were completely contrary to their expectations. They expected that the Net would prove socially healthier than television, since the Net allows users to choose their information and to communicate with others.
The fact that Internet use reduces time available for family and friends may account for the drop in well-being, researchers hypothesized. Faceless, bodiless “virtual” communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallow. Another possibility is that exposure to the wider world via the Net makes users less satisfied with their lives.
“But it’s important to remember this is not about the technology itself; it’s about how it is used,” says psychologist Christine Riley of Intel, one of the study’s sponsors.” It really points to the need for considering social factors in terms of how you design applications and services for technology.”

Watch out, Yahoo. There is a search engine out there with super speed and accuracy. It’s very cool.
Google is the Web’s largest search engine. In just two years it has gained a reputation for surprising speed and accuracy, delivering what you are looking for in a second. The site now does this 40 million times a day --- a number achieved without spending a penny on a TV or newspaper ad.
Google doesn’t need them. In the past six months alone, the site has won a Webby (the online version of the Oscar) for technical excellence, set a new record for search engines by indexing a billion Web pages.
Yahoo still has ten times the audience, but Google consistently ranks first in customer satisfaction: 97% of users find what they are looking for most or all of the time. “You see people smile when they use it, like they’ve found something no one else knows about,” says Danny Sullivan, editor of an online newsletter.
No one is smiling more than Larry Page, 27, and Sergey Brin, 26, who seem certain to become billionaires when the company goes public, probably sometime in 2004. they make a great comedy duo(成對(duì)的表演者)。When they first met as Ph. D. students, the pair say, they found each other horrible – “I still find him horrible,” adds Brin – but driven together by a computer-science project aimed at coming up with better ways of searching the Web.
The idea behind the Google is that traditional search engines are stupid. They think relevance (關(guān)聯(lián)) is based on repetition; if you type in a request for Tiger Woods, say, you’ll get websites listed according to how many times those words appear. Not only is this no guarantee of quality, but it’s also open to abuse. If you own a Tiger fan site and want to lead more people to it, simply type his name thousands of times in the site’s source code(編碼).
1What does the underlined word “them” in the third paragraph refer to?
A. 40 million times              B. Speed and accuracy. 
C. TV and newspaper ads.        D. Web pages
2. Which of the following win greater customer satisfaction?
A. Yahoo        B. Tiger Woods      C. Larry Page     D. Google
3. It can be inferred that Page and Brin ______________.
A. hold very important positions in Google
B. are two ordinary computer programmers of Google.
C. used to hate each other very much
D. hold quite different opinions of computer-science
4. We can learn from the last paragraph that ___________.
A. Google is open to abuse
B. Google remains a traditional search engine
C. Google thinks relevance is based on repetition
D Google is better than traditional search engines

U.S. airlines are seeing a major interruption because of hundreds of flights canceled due to the ash cloud from the Icelandic volcano, but European flight companies will face the biggest losses.
The airline business has been tough: The decline dramatically slowed traffic; February heavy snow forced U.S. airlines to cancel thousands of flights; and now the ashes from the volcano stopped all traffic in and out of northern Europe for days.
"For U.S. flight companies, it'll be a relatively short-term hit," said Michael Boyd, president of Boyd Group International, an aviation (航空學(xué)) consulting firm. "We think right now they're down about $80 million in terms of lost income, and they're down domestically about 80,000 passengers that would have been flying domestically but aren't because they can't get here."
Delta announced that volcano-related interruption grounded about 400 flights until Monday at a cost of $20 million in lost revenues. But compare that to the recent snowstorms, when the airline canceled 7,000 flights and lost $65 million in revenue.
The disruption has created uncertainty for customers, but analysts say U.S. airlines won't face as many costs as you might think. They are not flying in extra planes to handle the passengers in trouble because, airline analyst Robert Mann said, companies simply don't have them.
"Airlines run a very lean operation now," Mann said. "So, since there are no spare aircraft or crews, the airlines will attempt to maximize loads on every one of their aircraft that do fly. But it may take days, or in some cases a week or so, to get some of these customers to where they want to go."
46. Which negative consequences mentioned in the passage did the disasters cause?
A. coldness, pollution and airlines’ losses    
B. airport damage, pollution and slow traffic
C. passenger delay, coldness and airport damage   
D. passenger delay, airlines’ losses and slow traffic
47. Which of the following statements is true according to the passage?
A. The fewest airplanes will fly the trapped passengers to their destinations.
B. All the customers are sure to be sent to their destinations in time.
C. The U.S. and U.K. airlines suffered the same losses in the natural disasters.
D. The volcano eruption reduced the traffic to and from northern Europe.  
48. What does the last paragraph mainly tell us?
A. the troubles that the airlines will face after the ash cloud disappears
B. the measures that the airlines will take to maximize their profit
C. the present situation of the airlines and their plan to deliver the passengers
D. the reasons why the airlines run a fine operation
49. Why will it take a long time for airlines to send the passengers to their different destinations?
A. Because the passengers enjoy staying in airports to talk with one another.
B. Because the airlines don’t have spare planes or employees to serve.
C. Because the airlines don't have enough financial support after the disaster.
D. Because the passengers are asking for full refund from the airlines.
50. The passage is most probably from_______.
A.a(chǎn) novel                                  B.a(chǎn) news report        
C.a(chǎn) magazine                               D.a(chǎn) thesis

In summer, millions of people will head for the beach. And while the ocean can be a great place to swim and play, it may also be useful in another way. Some scientists think that waves could help make electricity.
“Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave? Or have you jumped in the water and felt the energy as waves crashed over you?” asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh in Scotland.“There is certainly a lot of energy in waves.”
Scientists are working on using that energy to make electricity.
Most waves are created when winds blow across the ocean.“The winds start out by making little ripples (波紋) in the water, but if they keep on blowing , those ripples get bigger and bigger and turn into waves, ”Taylor said.“Waves are one of nature’s ways of picking up energy and then sending it off on a journey.”
When waves come towards the shore, people can set up dams or other barricades to block the water and send it through a large wheel called a turbine (渦輪) .The turbine can then power an electrical generator (發(fā)電機(jī)) .
The United States and a few other countries have started doing research on wave energy , and it is already being used in Scotland.
The resource is huge.We will never run out of wave power, besides, wave energy does not create the same pollution as other energy sources, such as oil and coal.
Oceans cover three quarters of the earth’s surface.That would make wave power seem perfect for creating energy around the world.There are some drawbacks, however.
Jamie Taylor said that wave power still cost too much money.He said that its effects on animals in the sea were still unknown.Plus, wave power would get in the way of fishing and boat traffic.
With more research, however, “many of these problems might be overcome,” Taylor said.“Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is growing quickly throughout the world.Finding more energy sources is very important, for traditional sources of energy like oil and gas may run out some day.”
In the future, when you turn on a light switch, an ocean wave could be providing the electricity!
68.Which of the following is NOT true?
A.Wave power costs too much money.
B.Wave energy creates the same amount of pollution as other energy sources.
C.Wave power affects fishing and boat traffic.
D.Wave power may affect marine animals.
69.We can infer from the passage that ______.
A.finding more new energy sources is not necessary because of wave energy
B.wave energy is a resource that will never run out and is used all over the world
C.wave power is perfect for creating energy around the world
D.wave power doesn’t create any pollution
70.The underlined word “drawbacks” probably means ______.
A.regrets      B.a(chǎn)dventures       C.disadvantages          D.difficulties
71.What can be the best title for the passage? 
A.How to Get Electricity by Waves.       B.The Advantages of Wave Energy.
C.Can Waves Make Electricity?  D.The Disadvantages of Wave Energy.

If you’re planning on traveling, there are a few simple rules about how to make life easier both before and after your journey.
First of all, always check and double-check departure (行程) time. It is amazing how few people really do this carefully. Once I arrived at the airport a few minutes after ten. My secretary had got the ticket for me and I thought she had said that the plane left at 10:50. When I arrived at the airport, the clerk at the departure desk told me that my flight was closed. Therefore, I had to wait three hours for the next one and missed an important meeting.
The second rule is to remember that even in this age of credit cards, it is still important to have at least a little of the local currency (貨幣) with you when you arrive in a country. This can be necessary if you are flying to a place few tourists normally visit. A few years ago I was sent to Tulsa, Oklahoma. I flew there from London via (經(jīng)由) Dallas, with very little time to change planes in between. I arrived there at midnight and the bank at the airport was closed. The only way to get to my hotel was by taxi and because I had no dollars, I offered to pay in pounds instead.
“Listen! I only take real money!” the driver said angrily. Luckily I was able to borrow a few dollars from a clerk at the hotel, but it was very embarrassing (令人難堪的).
The third and last rule is to find out as much as you can about the weather at your destination before you leave. I feel sorry for some of my workmates who travel in heavy suits and raincoats in May, when it is still fairly cool in London or Manchester, to places like Athens, Rome or Madrid, where it is already beginning to get quite warm during the day.
40. According to the passage, it’s obvious that ______.
A. the author learns some rules of traveling from his own experience
B. the author doesn’t plan his trips or journeys carefully
C. Englishmen like to wear heavy suits wherever they travel
D. the American taxi driver never travels to England
41. What should you make sure first before setting off?
A. When you will leave.      B. Where you will go.
C. How you will travel.        D. Whom you will go with.
42. What does the underlined word “there” in Paragraph 3 refer to?
A. London.            B. Manchester.            C. Tulsa.        D. Dallas.
43. Which of the following is TRUE according to the passage?
A. The author tells people to choose warm places as their travel destinations.
B. You should remember to take credit cards when traveling.
C. You should know more about the weather of the place you’ll visit.
D. You should take enough change when you travel to another country.
