The twentieth century saw greater changes than any century before: changes for the better,
changes for the worse; changes that brought a lot of benefits to human beings, changes that put man in danger. Many things caused the changes, but, in my opinion, the most important was the progress in science.
Scientific research in physics and biology has vastly broadened our views. It has given us a deeper knowledge of the structure of matter and of the universe; it has brought us a better understanding of the nature of life and of its continuous development. Technology m the application of science m has made big advances that have benefited us in nearly every part of life.
The continuation of such activities in the twenty-first century will result in even greater advantages to human beings: in pure science -- a wider and deeper knowledge in all fields of learning; in applied science -- a more reasonable sharing of material benefits, and better protection of the environment.
Sadly, however, there is another side to the picture. The creativity of science has been employed in doing damage to mankind.  The application of science and technology to the development and production of weapons of mass destruction has created a real danger to the continued existence of the human race on this planet. We have seen this happen in the case of nuclear weapons, Although their actual use has so far occurred only in the Second World War, the number of nuclear weapons that were produced and made ready for use was so large that if the weapons had actually been used, the result could have been the ruin of the human race, as well as of many kinds of animals.
William Shakespeare said, “The web of our life is of a mingled yarn (紗線), good and ill together.” The above brief review of the application of only one part of human activities----- science seems to prove what Shakespeare said. But does it have to be so? Must the ill always go together with the good? Are we biologically programmed for war?
小題1:Which of the following best shows the structure of the passage?
A．B．C．D．
小題2:From the fourth paragraph, we can infer that________.
A．a(chǎn) great many nuclear weapons were actually used for war
B．a(chǎn) large number of nuclear weapons should have been used for war
C．the author is doubtful about the ruin of human beings by nuclear weapons
D．the author is anxious about the huge number of nuclear weapons on the earth
小題3:The underlined word "mingled" in the last paragraph most probably means________.
A．simpleB．mixedC．sadD．happy
小題4:What do you think the author is most likely to suggest if he continues to write?
A．Further application of science to war.
B．More reading of William Shakespeare.
C．Proper use of science in the new century.
D．Effective ways to separate the good from the ill.

小題1:A
小題2:D
小題3:B
小題4:C

小題1:考查考生對文章整體結構的把握能力。綜觀全文，第一段引出話題，第二和第三段講述科學上的進步給人類帶來的好處(good)，而第三段則講述了科學上的進步給人類帶來的傷害（ill），第五段對全文進行了概括總結。
小題2:考查考生的邏輯推理判斷能力。從本段可以推斷出作者認為大量核武器的生產(chǎn)和準備投入使用將會給人類和地球上很多動物帶來滅頂之災，作者對此感到擔憂。
小題3:考查考生猜測詞義的能力。根據(jù)下文的good and ill together（好壞并存）進行猜測。
小題4:考查考生領會作者寫作臆態(tài)并進行推理判斷的能力。通過文章結尾的三個反問句可以看出作者在此問題上的觀點，即如果人們正確的運用科學，它只會給人類帶來好處，不一定會帶來害處。據(jù)此，接下來作者必然圍繞如何正確運用科學這一話題來展開。

It will be hot—hot enough that most locals will have cleared town for cooler places. But because athletes competing at the 2004 Olympics have no choice but to stay in the hot weather, many plan to turn to science to stay cool.?
Some will put their hands in ice water just before competing and nearly all will be wearing fabrics(織物) designed with hot weather in mind.?
“Normally we warm up before exercise,”said Gordon Sleivert, director of sports science and medicine at the Canadian Sport Center in Victoria, British Columbia.“But in this case we're taking the warm out of warm up. It's like pre-cooling.”
Experts are predicting(預測) the average high this August in Athens will be 90 degrees Fahrenheit, with temperatures often reaching above 100(the average temperature in Sydney for the 2000 summer games was 64).?
Although some events, such as the marathon, will start early(1 a.m.) to avoid hot weather, other competitors will be pushing their limits during high temperatures.?       Drinking lots of water will help athletes keep cool, but humidity(濕度) remains a problem. The body's ability to cool down is weakened by damp air since sweat drips off the skin rather than evaporates(蒸發(fā)),resulting in dehydration(脫水) without the cooling.?
“Getting hot is a real problem because when our brains heats up, the brain waves are more like when you're really sleepy. Everything feels harder,” said Sleivert.
小題1: The passage mainly tells us that _______.
A．why it is very hot in Athens?
B．the hot weather is a big problem for Olympic athletes?
C．how important science is to every athlete?
D．the Olympics will be put off because of the hot weather?
小題2:The underlined sentence “other competitors will be pushing their limits during high temperatures”in the fifth paragraph means _______.?
A．Olympic athletes will put off their competition time?
B．some events in the Olympics will have to be put forward?

D．competitors will have to try their best to compete under any condition?
小題3:The following things will be likely to happen in the hot weather EXCEPT _______.
A．dehydration?
B．being sleepy?
C．that the blood in the body can become less and less?
D．that the body's ability to cool down is weakened

Everywhere man is altering the balance of nature．He is facilitating the spread of plants and animals into new regions, sometimes deliberately, sometimes unconsciously．He is covering huge areas with new kinds of plants, or with houses, factories, slag-heaps and other products of his civilization．He exterminates some species on a large scale, but favours the multiplication of others．In brief, he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million．
Many of these changes which he has brought about have had unforeseen consequences．Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade, or that the provision of pot cacti for lonely settlers’ wives would have led to Eastern Australian being overrun with forests of Prickly Pear? Who would have prophesied that the cutting down of forests on the Adriatic coasts, or in parts of Central Africa, could have reduced the land to a semidesert, with the very soil washed away from the bare rock? Who would have thought that improved communications would have changed history by the spreading of disease-sleeping sickness into East Africa, measles into Oceania, very possibly malaria into ancient Greece?
These are spectacular examples; but examples on a smaller scale are everywhere to be found．We make a nature sanctuary for rare birds, prescribing absolute security for all species; and we may find that some common and hardy kind of bird multiplies beyond measure and ousts the rare kinds in which we were particularly interested．We see, owing to some little change brought about by civilization, the starling spread over the English country-side in hordes．We improve the yielding capacities of our cattle; and find that now they exhaust the pastures which sufficed for less exigent stock．
小題1:The following examples except ________ reflect man altering the balance of nature．
A．man is covering huge areas with new kinds of plants
B．man is facilitating the spread of animals into new regions．
C．man is killing some species on a large scale
D．man is getting to know the importance of keeping the balance of nature．
小題2:What had a piece of Canadian waterweed cause?
A．Eastern Australian was overrun with forests．
B．Half the waterways of Britain blocked for a decade．
C．In parts of central Africa, the land reduced to a semidesert．
D．Disease-sleeping has been caused．
小題3:What have spread diseases?
A．Disease-sleeping sickness．B．Measles．
C．Improved communications．D．Malaria．
小題4:We make a nature sanctuary for rare birds but __________
A．some common and hardy kind of bird multiplies
B．rare kinds multiply
C．a(chǎn)ll bird multiply
D．no bird multiply

Disposing(處理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste-disposal problem becomes increasingly difficult.
During the eighteenth century, it was usual for several neighboring towns to get together to select a faraway spot as a dumpsite. Residents or trash haulers(垃圾托運者) would transport household rubbish, rotted wood, and old possessions to the site. Periodically(定期的) some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by.
Factories, mills, and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem.
Several facts make these choices unacceptable to modern society. The first problem is space. Dumps, which are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. Property is either too expensive or too close to residential(住宅區(qū)的)neighborhoods. Long-distance trash hauling has been a common practice, but once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is almost nonexistent.
Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste, however, continues to grow.
Recycling efforts have become commonplace, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a city's reusable waste.
小題1:The most suitable title for this passage would be ______.
A．Places for Disposing WasteB．Waste Pollution Dangers
C．Ways of Getting Rid of WasteD．Waste Disposal Problem
小題2:During the 18th century, people disposed their waste in many ways EXCEPT for ______.
A．burying itB．recycling it
C．burning itD．throwing it into rivers
小題3:What can be inferred from the fourth paragraph?
A．Farm areas accept waste from the city in modern society.
B．There is cheap land to bury waste in modem society.
C．It is difficult to find space to bury waste in modem society.
D．Ways to deal with waste in modem society stay the same.
小題4: The main purpose of writing this article is to ________.
A．draw people's attention to waste management
B．warn people of the pollution dangers we are facing
C．call on people to take part in recycling programs
D．tell people a better way to get rid of the waste

Just five one-hundredths of an inch thick and light golden in color, the Lay's potato chip seems an unlikely weapon for global control. But its maker, Frito-Lay doesn't think so. "Potato chips are a snack food for the world , "said Salman Amin, the company's head of global marketing. Amin believes there is no corner of the world that can resist the attractions of a Frito-Lay potato chip.
Frito-Lay is the biggest snack maker in America owned by Pepsico and accounts for over half of the parent company's $ 3 billion profits every year. But the U.S. snack food market is largely saturated(飽和),and to grow, the company has to look overseas.
Its strategy rests on two beliefs: first, a global product offers economies of scale(規(guī)模) with which local brands cannot compete. And second, consumers in the 21st century are drawn to "global" as a concept. "Global" does not mean products that are consciously regarded as American, but ones that consumers--especially young people--see as part of a modern, innovative(創(chuàng)新的) world in which people are linked across cultures by shared beliefs and tastes. Potato chips are an American invention, but most Chinese, for example, do not know that Frito-Lay is an American company. Instead, Riskey, the company's research and development head, would hope they associate the brand with the new world of global communications and business.
With brand concept a key factor, Riskey ordered a redesign of the Frito-Lay logo(標識). The logo, along with the company's long-held marketing image of its chips, would help make the company's global development very easy.
The managers admit that they try to change national eating habits to a food created in America, but they don't think that means economic imperialism (霸主).  "We're making products in those countries, we're adapting them to the tastes of those countries, building businesses and employing people and changing lives , "said Steve Reinemund, Pepsico's chief manager.
小題1:Amin's belief is that _________.
A．people all over the world enjoy eating their potato chips
B．the light golden color increases the attraction of their potato chips
C．they must find new ways to promote sales in their country
D．potato chips can hardly control the world market
小題2:What do we learn about Frito-Lay from Paragraph 2?
A．It gives half of its profits to its parent company every year.
B．It needs to turn to the world market for development.
C．Its products used to be popular among overseas consumers.
D．Its development has caused fierce competition in the snack market.
小題3:One of the concepts on which Frito-Lay bases its development strategy is that __________.
A．consumers worldwide today are attracted by global brands
B．products suiting Chinese consumers' needs bring more profits
C．local brands cannot compete successfully with American brands
D．products identified as American will have promising market value
小題4:Why did Riskey have the Frito-Lay logo redesigned?
A．To suit changing tastes of young consumers.
B．To compete with other American chip producers.
C．To change the company's long-held marketing image.
D．To promote the company's strategy of globalization.

Directions: Read the following passage. Answer the questions according to the information given in the passage and the required words limit. Write your answers on your answer sheet.
A political scientist from Indiana University whose work exploring how people come together to preserve their collective resources may provide important clues in the fight against climate change has become the first woman to win the Nobel prize for economics.
Elinor Ostrom, 76, shares 2009 Nobel prize with fellow American academic Oliver Williamson, 77. The Royal Swedish Academy of Sciences announced to the world the pair had been chosen to win the 40th prize in economic sciences.
For Ostrom, the award came, as a "big surprise". To rise to the peak of her area of learning has been a big journey, as she has had to struggle against her own weaknesses and the barriers of the system. At school in Los Angeles, she suffered from stuttering. She also faced the barriers common to most women of her generation entering the sciences --- she was discouraged from taking a PhD when she applied for graduate school.
Her field of study has been striking for how cross-disciplinary it is. Early on she gained a reputation for bringing economics, political science and sociology together.
What interests her is how common property can be managed successfully through groups in society. The findings of her research have been striking, as the Nobel committee pointed out, because they have challenged the traditional assumption that common property is poorly managed unless it is either controlled by government or privatized. She has shown how different individuals can band together and form collectives that protect the resource at hand.
“A lot of people are waiting for more international co-operation to solve global warming.” Ostrom said , “It is important that there is international agreement, but we can be taking steps at family level, community level, civic and national level … There are many steps that can be taken. That will not solve it on their own but continuously will make a big difference.”
81. How did Ostrom feel when she got the prize?  (not more than 3 words)
82. What does “cross-disciplinary” mean according to the passage?  (not more than 9 words)
83. Why was Ostrom advised not to take a PhD when she applied for graduate school?  (not more than 9 words)
84. Why was Ostrom awarded the Nobel prize for economics?  (not more than 16 words)

The city of Rome has passed a new law to prevent cruelty to animals. All goldfish bowls are no longer allowed and dog owners must walk their dogs.
This comes after a national law was passed to give prison sentences to people who desert cats or dogs.
“The civilization of a city can be measured by this,” said Monica Cirinna, the councilor (議員)behind the new law.
“It’s good to do whatever we can for our animals who in exchange for a little love fill our existence with their attention,” she told a Rome newspaper.
The newspaper reported that round bowls don’t give enough oxygen for fish and may make them go blind.
“Rome has tried to protect fish more than anywhere else in the world. It stands out for recognizing that fish are interesting animals who deserve our respect and compassion every bit as much as dogs and cats and other animals,” said Karin Robertson, a director of the People for the Ethical Treatment of Animals.
Last year a law was passed in Italy that gives people who desert pets big fines and prison sentences. Since then local governments have added their own animal protection rules.
The northern city of Turin passed a law in April to give pet owners fines of up to $598 if they do not walk their dogs three times a day.
The new law in Rome also says that owners mustn’t leave their dogs in hot cars or cut their dogs’ tails to make them look lovelier. The law also gives legal recognition to the “cat ladies” who feed homeless cats. The cats live all over the city from ancient ruins to modern office car parks.
小題1:The new law passed in Rome will ________.
A．help improve fishing environment
B．guarantee better conditions for goldfish
C．stop people from catching goldfish
D．discourage keeping goldfish at home
小題2:People in Rome believe that the civilization of a city can be judged by its ________.
A．exchanges with other cities
B．protection for ancient ruins
C．a(chǎn)wareness of animal protection
D．recognition of animal lovers
小題3:The underlined word “compassion” in Paragraph 6 is the closest in meaning to ________.
A．pityB．praiseC．supportD．popularity
小題4:People may break the law in Turin if they ________.
A．keep their dogs or cats in cars
B．feed homeless animals in car parks
C．raise their cats near ancient ruins
D．shut their dogs home all day long

Before the early 1960’s people interested in the differing roles of the left and right hemispheres(半球) of the brain depended almost entirely on facts drawn from animal research, form studies of patients with one-sided brain damage. But it was possible to find out which brain hemisphere was most involved in speech and other functions in normal people by having them listen to two different words coming to the two ears at the same time. This became known as the “dichotic listening” procedure. When several word pairs are given in a row, people are unable to report them all, and most right-handers prefer to report, and report more correctly, words given to their right ears. This seems to be related to the fact that signals from the right ear, although sent to both hemispheres, are better sent to the left hemisphere which controls speech. People who have speech represented(回憶) in the right hemisphere, a very unusual occurrence even in left-handed people, more correctly report what their left ears hear.
In contrast to the right-ear advantage for speech, there is generally a left-ear advantage for another type of auditory(聽覺的) signal: music. When right-handed people listen to melodic patterns they report them better from the left ear.
小題1:Which of the following would be the most proper title for the passage?
A．An Introduction to Speech Damage in Patients with Brain Damage.
B．An Investigation into the Role of the Brain’s Hemispheres.
C．An Analysis of Left and Right-handed People.
D．An Examination of “Dichotic Listening”.
小題2:The “dichotic listening” procedure could best be described as hearing _______.
A．two different words in the same ear twice
B．the same word twice in the same ear
C．two different words in different ears
D．two different words twice in two ears
小題3:according to the passage, right-handed people normally _______.
A．have better hearing in their both ears
B．have little difficulty in reporting words given to their right ears
C．a(chǎn)re unable to report word pairs given to their left ears
D．correctly report word pairs given in a row
小題4:according to the passage, music is best appreciated when heard by _______.
A．the left ear of right-handers
B．people with a left-ear advantage
C．left-handers in their right ears
D．right-handed people who understand melodic patterns

Learning to save money when you're young is an important lesson. All good lessons arid habits begin early, and saving is a skill that everyone needs. Many people—adults included—do not have a good sense of saving for the long run. 　　  
I have been lucky to learn this lesson early because I have had a grass-cutting business since I was 10 years old. Of the money I make I spend about 10 percent and save the other 90. 　　
Making sure you save and don't spend too much is a good way to build up wealth. I have put my earnings in a bank. Many teens I know spend all the money they earn so it never has a chance to grow. Young people should realize that their teenage years are a great time to begin saving. 　　
At high school many parents pay for almost everything, so your expenses can be small. If you have a lob, you should have fun with some of the money. But you should also save some so that it will grow. Then you can begin planning for your future. When you spend money, you not only lose that money, but also lose the interest you could have earned by saving it. 　　
After high school, college is expensive and then "real" life begins, with expenses such as food and rent. If you can hold onto a good percentage of the money you earn as a teen, going to college and buying a house will be much easier.________________, the more time the money has to grow. If you are in your thirties without any savings, you will always have to struggle. The earlier you begin saving, the easier it is to create a nest egg.  
Later in life it can be hard to start saving because general costs of living are more expensive and you may only have enough to pay your bills. If you want to buy a house and have a family, you need money to start with, which comes from saving. 　　
Many say money cannot make you happy, and this is true. But money can help you to lead a secure life. 　　  
Saving early will mean you will have to work for fewer years when you are older. It will also allow you to spend time doing the things that you want to do.
In addition to this, it will mean you can live the way you want to without worrying.
1.What’s the best title of the passage? 
2.Which sentence in the passage is the closest in meaning to the following one?
As long as you save early, you’ll do less work to live well at your old age.
3.Please fill in the blank in the passage with proper words or phrases to complete the sentence.(within 10 words)
4 According to the passage,.what do you think of saving ?(within 30 words)
5.Translate the underlined sentence into Chinese.
