A
Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines.
Some scientists have proposed setting a noise limit of one hundred and twenty decibels (分貝) in oceans. They have observed that noises at the level can frighten and confuse (使困惑) whales.
A team of American and Canadian scientists discovered that loud noises could seriously injure some animals. They found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died.
Some researchers whose work depends on ocean sounds object to (反對) a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research. Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists agree that noise is a greater danger than they believed. They want to prevent noises from harming creatures (生物) in the ocean.
56. According to the passage, which of the following is increasingly dangerous to sea creatures?
A. The man-made noises.            
B. The noises made by themselves.
C. The sound of earthquakes.         
D. The sound of ice-breaking.
57. Concerning the effect of noises on whales, which of the following is TRUE?
A. They are deaf to noises.           
B. Noises at a certain level may hurt them.
C. Noises could kill them.            
D. Noises will cause them to lose their eyesight.
58. Some scientists think that the noise limit of one hundred and twenty decibels would _________.
A. prevent them doing their research work    
B. benefit them a lot in their research work
C. do good to their health                 
D. increase the industrial output
59. According to the last paragraph, what will scientists most probably do in the future?
A. They will study the effect of different noises in the sea.
B. They will work hard to make no noise.
C. They will never do any scientific research in the sea.
D. They will protect sea animals from harmful noises.

D
As they migrate(遷移),butterflies and moths choose the winds they want to fly with,and they change their body positions if they start floating in the wrong direction.This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances.Scientists have long thought that insects were simply at the mercy of the wind.
Fascinating as their skills of flight are,migrating behavior has been difficult to study in insects because many long distant trips happthousands of feet above ground.Only recently have scientists developed technologies that can detect such little creatures at such great heights.
To their surprise,though,the insects weren’t passive travelers on the winds.In autumn,for example,most light winds blew from the east,but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes.
Even in the spring,when most winds flowed northward,the insects didn’t always go with the flow.If breezes weren’t blowing in the exact direction they wanted to go,the insects changed their body positions to compensate.Many migrating birds do the same thing.
The study also found,butterflies and moths actively flew within the air streams that pushed them along.By adding flight speeds to wind speeds,the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour.The findings may have real-world applications.With climate warming,migrating insects are growing in number.Knowing how and when these pests move could help when farmers decide when to spray their crops.
71.What’s the main idea of the text?
A.Insects migrate with the seasons.     B.Wind helps insects greatly in migrating.
C.Windsurfing insects have real direction.D.Scientists have trouble in observing insects.
72.Scientists originally thought that____________.
A.insects always waited for their favourable winds
B.insects chose the winds they wanted to ride
C.insects were just blown about by the wind
D.insects positioned themselves in the winds
73.It is not easy to stuay the migrating behavior of the insects because____________
A.the little creatures can fly very fast     B.they have no regular migrating courses
C.the wind’s direction is hard to foresee    D.their flight is long and high above ground
74.We can learn from the text that______________.
A.insects fly in the way birds do
B.insects travel more easily in autumn
C.insects never position themselves when flying low
D.insects rest a lot when the wind pushes them along
75.According to the passage,the findings can              
A.increase insects in number         B.instruct farmers when to spray
C.prevent climate warming       D.help protect insects

C
The announcements by the NASA,in the form of several Web site postings and a video posted on YouTube,were in response to worries that the world will end on Dec.21,2012.
The doomsday(末日) rumour reached a high point with the release of the new movie “2012”,directed by Roland Emmerich.In the movie,Yellowstone blows up, showering the continent with black ash.Tidal waves wash over the Himalayas,where the governments of the planet have secretly built a ship which a select 400,000 people can ride out the storm.There are hundreds of hooks devoted to 2012,and millions of Web sites,depending on what combination of“2012”and“doomsday”you type into Google.All of it,astronomers say, is nonsense.“Most of what's claimed for 2012 relies on wishful thinking and ignorance of astronomy.”Ed Krupp, an expert on ancient astronomy,wrote in an article in the November issue of Sky&Telescope.
“I get angry at the way people are being influenced and frightened to make money,” Morrison said.“There is no right to frighten children to make a buck.”suggested David Morrison,an astronomer at the NASA Ames Research Center in Moffett Field,Calif.He said he had been getting about 20 letters and e—mail messages a day from people as far away as India scared out of their wits.Morrison said he did not blame the movie for all this,as much as many other supporters of the Mayan prediction.But then,he said,“my doctorate is in astronomy,not psychology.”
In an e—mail exchange, Krupp said:“We are always uncertain about the future,and we always consume representations of it.We are always attracted by the romance of the ancient past.”A NASA spokesman,Dwayne Brown,said the agency did not comment on movies,leaving that to movie critics.But when it comes to science, Brown said, “we felt it was careful to provide a resource.”
If you want to worry,most scientists say,you should think about global climate change or nuclear war.But if ancient prophecies(預言)get you going,here are some things Morrison and the others think you should know.
64.Which of the following statements is TRUE according to the passage?
A.Dr.Morrison blamed the Movie“2011”for the panic it aroused in the public around the world.
B.People who watched the movie were seared and firmly believed that the end of the world was coming.
C.In terms of science it was better to provide evidence and theory at the same time.
D.Dr.Morrison thought it was not right to make money by frightening people.
65.It can be inferred from the text that        .
A.a(chǎn)stronomers think that doomsday is likely to happen in the near future
B.the reason why the NASA posted web site postings was to make people interested in astronomy
C.scientists think we shouldn't worry about doomsday but show concern about environment protection
D.most astronomers agree that the world is not ending—at least anytime soon
66.Which of the following would be the best title?
A.A New Movie“2012”            B.Is Doomsday Coming?
C.End-of-the-World Stories          D.Astronomers Comment on Movies
67.What would the author probably discuss in the paragraph that follows?
A.Evidence that the Mayans thought something special would happen in 2012.
B.What will really happen in 2012.
C.The reason why there is no need to worry about doomsday.
D.Ancient stories about the end of the world.

(D)
At a certain time in our lives we consider every place as the possible site for a house. I have thus searched the country within a dozen miles of where I live. In imagination I have bought all the farms, one after another, and I knew their prices.
The nearest thing that I came to actual ownership was when I bought the Hollowell place. But before the owner completed the sale with me, his wife changed her mind and wished to keep it, and he offered me additional dollars to return the farm to him. However, I let him keep the dollars and sold him the farm for just what I gave for it.
The real attractions of the Hollowell farm to me were its position, being about two miles from the village, half a mile from the nearest neighbor, bounded(相鄰) on one side by the river, and separated from the highway by a wide field. The poor condition of the house and fences showed that it hadn’t been used for some time. I remembered from my earliest trip up the river that the house used to be hidden behind a forest area, and I was in a hurry to buy it before the owner finished getting out some rocks, cutting down the apple trees, and clearing away some young trees which had grown up in the fields. I wanted to buy it before he made any more of his improvements. But it turned out as I have said.
I was not really troubled by the loss. I had always had a garden, but I don’t think I was ready for a large farm. I believe that as long as possible it is better to live free and uncommitted(無牽無掛). It makes but little difference whether you own a farm or not.
57.What do we know about the author?
A. He wanted to buy the oldest farm near where he lived.
B. He made a study of many farms before buying.
C. He made money by buying and selling farms.
D. He had the money to buy the best farm in the country.
58.Why did the author want to buy the farm in a hurry?
A. He was afraid the owner might change his mind.
B. He hoped to enlarge the forest on the farm.
C. He wanted to keep the farm as it was.
D. He was eager to become a farm owner.
59.The underlined words “the loss” in the last paragraph refer to _____?
A. the money the author lost in buying the farm
B. the sale of the garden in the Hollowell place
C. the removal of the trees around the house
D. the failure to possess the Hollowell place
60.What does the author believe as important in life?
A. To own a farm               B. To satisfy his needs
C. To be free from worries.       D. To live in the countryside.

B
 A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increases the risk.
 Research from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.
 Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (發(fā)生率) faster than any other cancer in the United States.
 But questions have been raised about sunscreen and whether it may have the opposite effect by allowing people to remain exposed to the sun longer without burning.
 The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer---are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.
 The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.
60.The underlined word “flaws” in the 2nd paragraph most probably means _________.
A.evidences         B.facts         C.faults         D.failures
61.People with fair skin and freckles ________.
A.seldom use sunscreen               B.a(chǎn)re more in danger of skin cancer
C.can be free from the harm of the sun       D.often expose themselves to the sun
62.We can learn from the passage that _________.
A.sunscreen users get skin cancer more often
B.the volunteers have proved the effect of the sunscreen
C.the new study has based on the experiences of volunteers
D.the number of skin cancer patients is increasing in America
63.Which of the following is the best title of the passage?
A.Sunscreen to Prevent Skin Cancer       B.Sunscreen to Increase Skin Cancer
C.Skin Cancer Caused by Sunscreen       D.Skin Cancer Caused by Freckles

Children who speak English as their first language are now a minority in inner-city London primary schools,official figures show.
Youngsters with foreign mother tongues form a majority at primary schools in 13 out of33 London cities. Across the country,English is a foreign language to more than one in seven primary school youngsters.
The figures from the Department for Children,Schools and Families (DCSF) point to major demographic (人口的) changes over the past few decades,with around a fifth of pupils now coming from ethnic minorities.
There are concerns that school finances are coming under stress from the growing numbers of youngsters requiring help with English. The government has been urged to provide more funding,and give fair treatment to schools with large concentrations of non-English speakers.
In Tower Hamlets almost four out of five youngsters do not have English as their mother tongue. In other areas,including Leicester,Luton and Bradford the proportion approaches 50 percent.
The figures indicate that many recent migrants have settled in London. Sir Andrew Green,F(xiàn)ounder and Chairman of Migration Watch UK,says,“These figures confirm the huge impact immigration is having on our society. When government funds are as tight as they are,this is bound to have a negative impact,since children for whom English is a second language need extra tuition (學費).”He adds,“In inner London it's hard to know with whom immigrant chil­dren are supposed to practice English,since the number of immigrant children is much larger than that of local. ”
A spokesman for DCSF stresses that the figures “only indicate the language to which a child was initially exposed at home,regardless of whether he or she comes to speak English fluently later on. It is only a relatively few recent arrivals for whom communication problems are serious”.“We are increasing funding to the Ethnic Minority Achievement Grant (助學金)to £206 million by 2010,to help bring students weak in English up to speed. We’re also equipping schools to offer effective English as an Additional Language teaching to new arrivals,”he adds
72.A minority of London primary school students speak English as their first language because
      .
A. local children prefer to speak other languages
B. more and more immigrant children are attending school in London
C. children learning English as an additional language need extra tuition
D. English is too difficult a language for primary school children to learn
73.Some people worry about      .
A. the increasing number of adults needing help with English
B. the government taking no measures to help the schools
C. non-English speakers putting school finances under stress
D. London schools not providing adequate service for children in need
74.It can be inferred from the passage that         .
A. most immigrant children make a great effort to learn English
B. the government used to treat non-English speakers unfairly
C. it's not easy to find English speakers for immigrant children in some parts of London to communicate with
D. local children are influenced by immigrant children
75.According to the spokesman for DCSF,the figures indi­cate       .
A. that children will speak English fluently later on
B. that immigration is having a huge impact on English society
C. what the language the children were exposed to first was
D. that funding is increasing to help students weak in English

A
Experts around Europe are discussing the embarrassing museum safety following the theft of two art masterpiece paintings on Sunday. A large hunt got under way Monday for thieves who walked into a lightly guarded museum in Oslo, Norway, tore two paintings off the wall and ran away.
Some expressed fear that works of art are in increasing danger from violent robbery — unless, said Deputy Culture Minister Yngve Slettholm, "we lock them in a mountain bunker(碉堡)."
Armed, masked robbers stole the Edvard Munch masterpiece "The Scream" and another of Munch's works, "Madonna," from Oslo's Munch Museum on Sunday as visitors watched in disbelief.
The purpose behind the robbery also remained unknown. But art experts guessed the thieves were either looking for money or wished to impress other criminals since it would be nearly impossible to sell such famous pieces of art.
This is the second time in a decade that a version of the painting has been stolen. Another version of "The Scream" was stolen from Oslo's National Gallery in February 2004, but recovered three months later. The Munch works were not insured against theft, because it was impossible to set a price on them, said John Oeyaas, managing director of Oslo Forsikring, the city-owned company that insured the paintings against damage. But he said the theft in broad daylight from one of Norway's most visited museums raises the question of security — "How can we make these artworks available to the public while still ensuring their safety?"
56. The stolen paintings were drawn by ______.
A. Oslo Forsikring        B. Yngve Slettholm              C. Edvard Munch          D. John Oeyaas
57.Which of the following description is correct about the theft?
A.The two paintings were stolen on Monday
B.Visitors to the museum saw the faces of the robbers
C.The thieves were looking for money
D.The thieves had weapons with them during the theft
58. The Oslo’s Munch Museum ______.
A.is one of the most popular museum in the country
B.had all its paintings insured against theft
C.were going to lock the paintings in a mountain bunker
D.had another version of “The Scream” stolen in 2004
59. What could be the best title for this passage?
A.Dangers of Violent Robbery
B.How to Ensure Safety of Artworks
C.Priceless Art Lost in Bold Theft
D.Famous Art Works Favored by Thieves

Monarch butterflies(黑脈金斑蝶)are a common summer sight in the northern United States and Canada . These large orange and black insects(昆蟲)brighten parks and gardens as they fly lightly among the flowers . What makes monarchs particularly interesting is that they migrate(遷飛)—all the way to California or Mexico and back . They are thought to be the only insect that does this.
Every year in the late summer monarchs begin their journey to the south. Those heading for Mexico go first for the Louisiana-Mississippi area, then fly across the Gulf of Mexico into Texas. Once in Mexico, they settle themselves in one of about fifteen places in a mountain forest filled with fir trees. Each place provides a winter home for millions of monarchs. The butterflies are so many that they often cover entire trees. When spring comes, they begin their long journey north. 
The question is often asked whether every butterfly makes the round-trip journey every year. And the answer is no. The average monarch lives about nine months. So one flying north might lay eggs in Louisiana and then die. The eggs of that generation may be found in Kentucky; the eggs of the next generation may end up in Wisconsin or Michigan. The last generation of the season, about the fourth , will make their way back to Mexico and restart the journey.
Scientists learn about monarchs’ migration by catching and making marks on the insects. By recatching a monarch with such a mark and noticing where it came from , the next scientist can get to know things like the butterfly’s age and its routing(路線).
64. One of the places where monarchs spend the winter is       .
A. the Gulf of Mexico                 B. an area in Mississippi
C. a forest in Mexico                D. a plain in Texas
65. The routing of monarchs’ migration can be learned       .
A. by collecting their eggs in the mountains
B. by examining the marks made on them
C. by comparing their different ages
D. by counting the dead ones in the forests
66. What is the subject discussed in the passage?
A. Life and death of monarchs         B. Scientists’ interest in monarchs.
C. Winter home of monarchs.               D. Migration of monarchs.

C
A new age is coming. Call it what you will: the service economy, the information age, the knowledge society. It all translates to a fundamental change in the way we work. Already we’re partly there, the percentage of people who earn their living by making things has fallen dramatically in the Western World. Today the majority of jobs in America, Europe and Japan are in the service industry, and the number is on the rise. More women are in the work force than ever before. There are more part-time jobs. More people are self-employed. But the range of the economic transformation can’t be measured by numbers alone, because it also is giving rise to important new way of thinking about the nature of work itself. Long-held ideas about jobs and careers, the skills needed to succeed, even the relation between individuals and employers — all these are being challenged.
We have only to look behind us to get some sense of what may lie ahead. No one looking ahead 20 years possibly could have foreseen the ways in which a single invention, the chip, would transform our world thanks to its applications in personal computers, digital communications and factory robots. Tomorrow’s achievements in biotechnology, artificial intelligence or even some still unimagined technology could produce a similar wave of dramatic changes. But one thing is certain: information and knowledge will become even more valid, and the people who possess it, whether they work in manufacturing or services, will have the advantage and produce the wealth. Computer knowledge will become as basic a requirement as the ability to read and write. The ability to solve problems by applying information instead of performing routine tasks will be valued above all else. If you cast your mind ahead 10 years, information service will be superior. It will be the way you do your job.
66. A characteristic of the new age mentioned in the passage is that        .
A. the service industry mainly relies on females
B. manufacturing industries are steadily increasing
C. more people are in the service industry than before
D. the work in the service industry is more comfortable than that in manufacturing industry
67. Which of the following is true according to the passage?
A. People’s traditional concepts about jobs need changing.
B. The relation between employees and employers is becoming tense.
C. More women than men are in the work force.
D. Part-time jobs are more welcome than full-time jobs.
68. By mentioning the invention of “the chip”, the author means to say that       .
A. we haven’t paid enough attention to the importance of high technology
B. the chip is the most important invention today
C. the power of science and technology is beyond our imagination
D. it’s a great challenge to apply new inventions to our life
69. We may draw a conclusion from the passage that        .
A. information will play a greater role in people’s work and daily life in the future
B. we can foresee the future if technology develops fast enough
C. the ability of performing routine tasks gives you an advantage in work
D. robots will replace people to do all the work both in manufacturing and service industries
70. The author’s attitude to the coming age is        .
A. doubtful         B. enthusiastic           C. satisfied        D. Uncertain
