    The world is not coming to an end on December 21, 2012, the US space agency insisted Monday in a rare campaign to dispel widespread rumors fueled by the Internet and a new Hollywood movie．
    The latest big screen offering from Sony Picture, 2012, arrives in theaters on Friday, with a 200-million-dollar production about the end of the world supposedly based on myths backed by the Mayan calendar．It is claimed that the end of time will come as a Planet X---or Nibiru---heads toward or collides with the Earth．
    Some websites accuse NASA of hiding the truth on the planet’s existence, but the US space agency condemned such stories as an “Internet hoax”．“There is no factual basis for these claims,” NASA said in a question-and-anwser posting on this website．“If such a collision were real, astronomers would have been tracking it for at least the past decade, and it would be visible by now to the naked eye．Obviously, it does not exist．Credible scientists worldwide know of no threat associated with 2012,” it insisted．“After all, our planet has been getting along just well for more than four billion years,” added NASA．
    There is another planet, Eris, floating in space．But the small planet similar to Pluto will remain safely fixed in the outer solar system and it can come no closer than four billion miles to the Earth, according to NASA．
    Earlier theories set the disaster for May 2003, but when nothing happened the date was moved forward to the winter in 2012 to coincide with the end of a cycle of the ancient Mayan calendar．
    NASA insisted the Mayan calendar in fact does not end on December 21, 2012, as another period begins immediately afterward．
    And even if the planets were to line up as some have forecast, the effect on our planet would be “negligible（unimportant）”, NASA said．
    “And while comets and asteroids （小行星） have always hit the Earth, big hits are very rare,” NASA noted．The last major impact was believed to be 65 million years ago, resulting in the end of dinosaurs．
    “We have already determined that there are no threatening asteroids as large as the one that killed the dinosaurs,” the space agency said．
    49．______ played a key role in the spread of the rumors．
    A．A new book               B．The Internet and a new Hollywood movie
    C．NASA                   D．An Indian calendar
    50．We can infer that ______．
    A．people didn’t take the rumor seriously
    B．Planet X --- or Nibiru does exist
    C．astronomers have been tracking Planet X for over ten years
    D．the rumor caused a panic among some people
    51．NASA thinks that Eris ______．
    A．might have a threat to the Earth     B．doesn’t have any threat to the Earth
    C．is too far away to be visible       D．is similar to our planet, where life might exist
    52．Which of the following is the best title?
    A．New Hollywood movie 2012
    B．December 21, 2012, Not the end of the world
    C．End of the ancient Mayan calendar
    D．How rumors came into being

    D
    Both warm-blooded and cold-blooded desert animals have ways to escape the desert heat. Warm-blooded desert animals, such as rats and mice, rest during the day, often staying in cool underground burrows. At night they search for food. Animals that are out during the day, such as cold-blooded lizards and snakes, are active only for short periods. As their body temperature rises, these reptiles move into the shade in order to cool down. In the early evening, when the sun grows weaker, the reptiles become more active and begin their search for food again.
    Getting enough water to survive is a major problem for all desert animals. Some desert animals, such as the kangaroo rat and the related jerboa, get water only from the food that they eat. Because these animals eat mainly dry seeds, they must survive on a tiny amount of water.
    Most deserts have only a small number of frogs and toads because these animals must be near water to survive. Yet even these creatures have adapted to desert conditions. When small amounts of water collect in temporary streams, the desert-living frogs and toads become active. After a rainfall, they lay their eggs. The eggs grow into tadpoles in a few days and into adults in just four weeks. When the puddles dry up, the adult frogs or toads dig into the ground. Their metabolism(新陈代谢) slows, and they stay beneath the ground until the next rain, which may be as good as a year away. Until then, their bodily activities continue at a reduced rate.
    The camel---often called the ship of the desert---is one of the most successful desert animals. Camels can go for long periods without water, but eventually they must drink. When water becomes available to them after a long drought, they may drink 95 liters of water or more. When water is not available, what helps camels survive the desert heat is the fat stored in their humps. A camel’s hump contains about 12 kilograms of fat. Fat is rich in hydrogen. As the fat is digested, hydrogen from the fat combines with oxygen in the air that the camel breathes. The result is H2O, or water. Each kilogram of fat that a camel digests produces about a liter of water.
    71. Desert animals are usually more active at night because ______.
    A. it is cooler at night           B.it is easier to find water
    C.they like the dark            D. they are less likely to be attacked at night
    72. Which of the following desert animals can get water only from the food?
    A. The camel.       B. The kangaroo rat.     C. The frog.      D. The toad
    73. Which of the following is TRUE according to the passage?
    A. All the desert animals rest during the day.
    B. All the desert animals don’t rest during the day.
    C. Cold-blooded desert animals don’t rest during the day.
    D. None of the cold-blooded desert animals go out during the day.
    74. The title for this passage could probably be ________.
    A. Hot Deserts                         B. Desert Animals
    C. How Desert Animals Get Water         D. Ways To Escape the Desert Heat
    75. The underlined word “burrows” in the first paragraph can be replaced by _________.
    A. holes     B. caves     C. rooms      D. Openings

    Could we "terraform" Mars —that is, change its frozen, thin-aired surface into something more friendly and Earthlike? Should we? The first question has a clear answer: Yes, we probably could．Spacecraft, including the ones now exploring Mars, have found evidence that it was warm in its youth, with rivers flowing into vast seas．And right here on Earth, we've learned how to warm a planet: just add greenhouse gases to its atmosphere．Much of the CO2 that once warmed Mars is probably still there, in frozen dirt and polar ice caps, and so is the water．
    Most of the work in terraforming, says NASA scientist Chris Mackay, would be done by life itself． "You don't build Mars," Mackay says．"You just warm it up and throw some seeds．" Powerful greenhouse gases could be produced from elements in dirt and air on Mars and blown into the atmosphere; by warming the planet, they would release the frozen CO2, which would quicken the warming and increase atmospheric pressure to the point where liquid water could flow．Meanwhile, says botanist James Graham of the University of Wisconsin, human settlers could seed the red rock with a succession （系列） of ecosystems ?first bacteria and lichens （地衣）, which survive in Antarctica, later mosses （苔藓）, and after one thousand years or so, redwoods．Getting breathable oxygen levels out of those forests, though, could take thousands of years．
    However, Mars is in no immediate danger．Some space scientists recently recommended going to the moon or an asteroid （小行星） first, and pointed out the space agency lacks the funds to go anywhere．It didn't estimate the cost of gardening a dead planet．
    72．What is the most essential to make Mars fit for living?
    A．Turn ice into flowing water．          B．Clean the dirty atmosphere．
    C．Make the atmosphere more suitable．    D．Go to the moon or an asteroid first．
    73．What does the author think of the idea ofterraforming Mars?
    A．We could do it．                            B．We couldn't do it．
    C．We should do it．                           D．We shouldn't do it．
    74．In the botanist's opinion, man needs to __________.
    A．enable Mars to clean its atmosphere
    B．build a greenhouse on Mars
    C．send some people to settle on Mars
    D．cultivate ecosystems from lower to higher life form
    75．What is the best title for the passage?
    A．Making Mars the New Earth．           B．A Good Way to Change the Universe
    C．Humans' Great Power．                     D．Terrible Science and Technology．

    D
    Are some people born clever, and others born stupid? Or is intelligence developed by our environment and experience? Strangely enough, the answer to these questions is yes. To some extent, person’s intelligence is fixed at birth, whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
    It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random(随意地) from the population, it is likely that their degree of intelligence will be completely different. If, on the other hand, we take two identical twins they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
    Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is  boring. We should soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degree of intelligence.
    68. The writer is in favor of the view that man’s intelligence is given to him
    A. at birth                          B. through education
    C. both at birth and through education    D. neither at birth nor through education
    69. If a child is born with low intelligence, he is unlikely to      
    A. become a genius so long as he or she works hard enough
    B. still become a genius if he should be given special education
    C. go beyond his intelligence limits even in rich surroundings
    D. never reaches his intelligence limits in his life
    70. The example of the twins going to a university and to a factory separately shows
    A. the importance of their intelligence      
    B. the role of environment on intelligence
    C. the importance of their positions        
    D. the part that birth plays
    71. What can be the best title for the text?
    A. Surroundings                           B. Intelligence
    C. Dependence on Environment              D. Effect of Education

    　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 (发生率) 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．are 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

    You’ve probably heard of the butterfly effect that small changes in one place can lead to great damage elsewhere. The Toy Story II, Made-in-China, appearing on the internet, TV screens and front pages of newspapers worldwide since August, was a live show. China’s fame as “the world’s factory” was badly damaged this summer by a small, but powerful magnet (磁铁), and colorful paints on toys.
    Mattel, the world’s largest toy company in the US, on August 14 announced the biggest recall (召回) of toys in its history. Among the recalled products were 17.4 million toys that had a design problem. They contained a small, powerful magnet that could harm children if it was swallowed. Another 2.2 million toys were recalled because of impermissible levels of lead (铅) in their paint.
    Although the designing problem has nothing to do with where the toys were made, the reports in the western media of the recall started to draw a horrible picture in many American parent’s minds.
    The toy recall issue followed shortly after recalls earlier in the year of Chinese-made pet food and toothpaste and left users all over the world worried about buying anything labeled (贴上标签) “Made-in-China”.
    The recall of the toys teaches Chinese companies that quality is extremely important. However, many of the complaints by western countries about Chinese goods reflect complicated feelings about the growing Chinese economy, culture differences and various political systems.
    However, more than 100 US multinational companies from many industries, including Boeing and Microsoft, signed a letter to the US Congress on September 28, to say no to the proposal against China. “Imposing (加强) unfair barriers to trade in the name of product safety is not a solution,” the companies wrote.
    Toys are made for children to learn about the reality world and become more mature (成熟), however, the Chinese version of Toy Story helps lots of adults learn about responsibility, importance of quality, understanding, communications, and more.
    53. The author mentions the butterfly effect at the beginning of the passage to ______.
    A. explain what the butterfly effect is
    B. tell the readers what causes the butterfly effect
    C. say that the toy effect is similar to the butterfly effect
    D. compare the differences between the butterfly effect and the toy effect
    54. Which of the following are the reasons mentioned to have caused the recall?
    a. The picture on the toys.
    b. The designing problem.
    c. The colorful paints on toys.
    d. The materials toys are made of.
    e. The small powerful magnet on toys.
    A. abe                   B. bde                   C. bce                   D. acd
    55. Boeing and Microsoft signed a letter to the US Congress because ______.
    A. the growing Chinese economy makes them afraid
    B. the Chinese companies have realized the importance of quality
    C. the Toy Story has made some Chinese companies suffer great losses
    D. they think it’s unfair to impose barriers in the name of product safety
    56. Which of the following can be the best title of the passage?
    A. Made in China.                              B. Butterfly Effect.
    C. Western Media.                              D. Toy Story.

    D
    A sunflower is a sunflower . A mobile phone is a mobile phone . But can you combine the two to do something for your local environment?
    As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury it in the garden or a plant pot and wait for it to flower. A biodegradable (能进行生物递降分解的) mobile phone was, this month, introduced by scientists.
    Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and able to change shape. Overtime it can also break down into the soil without giving out any toxic chemicals. British researchers used the new material to develop a phone cover that contains a sunflower seed. When this new type of cover turns into waste, it forms nitrates (硝酸钾). These feed the seed and help the flower grow. Engineers have designed a small transparent window to hold the seed. They have made sure it only grows when the phone is thrown away. "We've only put sunflower seeds into the covers so far. But we are working with plant experts to find out which flowers would perform best. Maybe we could put roses in next time," said one scientist.
    As phone technology is developing so quickly people are constantly  throwing their mobiles away. This means manufacturers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can offer some relief for nature, according to the scientists. "The seed is released and the flower grows in the pot so you don't have to concern yourself with the phone when you have finished using it," said Kerry Kirwan. She leads the research team, which is based at the University of Warwick in Britain.
    67. The main idea of the passage is ________ .
    A. the relationship between high tech and environment
    B. the phone technology is developing
    C. how to grow sunflowers
    D. mobile phone and environment
    68. The purpose of introducing a biodegradable mobile phone is ______ .
    A. to encourage consumers to recycle
    B. to prevent consumers from throwing their phones away
    C. to meet consumers’ need
    D. to help consumers know which flower can best perform
    69. What is the possible meaning of the underlined word ?
    A. pleasant    B. poisonous    C. useful    D. new
    70. Which of the following statements is NOT true ?
    A.Engineers have designed a small transparent window to hold the rose seed .
    B. Mobiles with biodegradable covers can do good to nature .
    C.Manufacturers are under pressure to find ways of recycling mobiles .
    D. The flower only grows when the phone is thrown away .

    A
    Forests have always been useful and important to man who make use of them in many ways. Every day trees are serving man everywhere. Trees supply man with fruits and building materials in the form of wood, without trees it would be impossible to build houses, boats, bridges and so on. Furniture such as desks, chairs and beds is made of wood, trees can stop man from terrible heat. They're also useful in preventing good and rich top soil from being washed away during heavy rains.
