    The exact number of English words is not known. The large dictionaries have over half a million entries, but many of these are compound words (schoolroom, sugar bowl) or different derivatives of the same word (rare—rarely, rarefy), and a good many are obsolete words to help us read older literature. Dictionaries do not attempt to cover completely words that we can draw on: the informal vocabulary, especially slang, localism, the terms of various occupations and professions; words use only occasionally by scientists and specialists in many fields; foreign words borrowed for use in English; or many new words or new senses of words that come into use every year and that may or may not be used long enough to warrant being included. It would be conservative to say that there are over a million English words that any of us might meet in our listening and reading and that we may draw on in our speaking and writing.
    Professor Seashore concluded that first?graders enter school with at least 2,000 words and add 5,000 each year so that they leave high school with at least 80,000. These figures are for recognition vocabulary, the words we understand when we read or hear them. Our active vocabulary, the words we use in speaking and writing, is considerably smaller.
    You cannot always produce a word exactly when you want it. But consciously using the words you recognize in reading will help get them into your active vocabulary. Occasionally in your reading pay particular attention to these words, especially when the subject is one that you might well write or talk about. Underline or make a list of words that you feel a need for and look up the less familiar ones in a dictionary. And then before very long find a way to use some of them.
    Once you know how they are pronounced and what they stand for, you can safely use them.
    46. In the author´s estimation, there are ____ words in English.
    A. more than half a million                B. at least 24,000
    C. at least 80,000                       D. more than a million
    47. The word “obsolete” most probably means ____.
    A. no longer in use  B. profound   C. colorful or amusing   D. common
    48. One´s recognition vocabulary is ____.
    A. less often used than his active vocabulary
    B. smaller than his active vocabulary
    C. as large as his active vocabulary
    D. much larger than his active vocabulary
    49. The author does not suggest getting recognition vocabulary into active vocabulary by ____.
    A. making a list of words you need and looking up the new ones in a dictionary
    B. everyday spending half an hour study the dictionary
    C. consciously using the words you recognize in reading
    D. trying to use the words you recognize
    50. From this passage we learn that ____.
    A. dictionaries completely cover the words we can make use of
    B. “schoolroom” is used in the passage as an example of a specialized term
    C. once you know how a word is pronounced and what it represents, you have turned it into your active word
    D. active vocabulary refers to words we understand when we read and hear them

    Exposure to environmental tobacco smoke (ETS)-also called “second-hand smoke” and “passive smoking” contains over 4 000 chemicals, including over 50 known carcinogens (致癌物) and many poisonous things. No safe level of ETS exposure has been proved. Nor is there any expectation that further research will identify such a level.
    Several recent reviews have confirmed the serious risks to health and life associated with passive smoking. Long time exposure to second-hand smoke has been proved as a cause of many of the same diseases caused by active smoking, including lung cancer, cardiovascular (心脏血管的) disease, and childhood disease.
    Living with a smoker has been shown to increase the risk of coronary heart disease (冠心病) among non-smokers by 25-30% (a recent study indicates that this figure may actually be higher). There is also growing evidence that passive smoking is causally linked to stroke in non-smokers, although further research is needed to estimate the risk.
    Second-hand smoke is especially dangerous for young children and infants, being associated with sudden infant death, pneumonia, bronchitis (支气管炎), asthma (哮喘) and respiratory symptoms as well as middle ear disease. ETS exposure in pregnant women can cause lower birth weight, foetal (胎儿的) death and preterm delivery.
    Most of the adverse health outcomes brought about by ETS show that the risk increases steadily with increasing exposure. The level of individual risk is lower compared to active smoking. Nevertheless, the fact that large numbers of people are exposed results in a substantial burden of disease.
    Action on smoke-free environments would not only protect people from the harm of ETS exposure but also contribute to the reduction of tobacco consumption in the whole population. The health effects of reduced passive and active smoking would include reduced illness and death from major disease types-in particular lung cancer, coronary heart disease, and stroke-and increased life expectancy.
    51. Which of the following statements is true? _______
    A. Although ETS contains many harmful things, it is not unsafe.
    B. The fact that second-hand smoke is safe has been recently found.
    C. It is expected that further research will be done to test the level of ETS.
    D. By far the safe level of ETS has not been found and will not in the future.
    52. Cardiovascular disease can be caused by _______.
    A. long time passive smoking    B. accidental active smoking
    B. occasional passive smoking   D. short term active smoking
    53. According to the article, the statements about the risk of coronary heart disease are wrong EXCEPT that________
    A. if you smoke, the risk of this disease will increase by 25-30%. 
    B. the non-smokers exposed to smoke will increase the risk of this disease by 25-30%.
    C. for the smokers, the risk of getting this disease is higher than that of the non-smokers.
    D. the non-smokers exposed to smoke will be more easily to get this disease than the smokers.
    54. What does the underlined word “delivery” mean? ________.
    A. Transferring to another     B. Giving birth   C. Throwing away   D. Giving out
    55. What’s the author’s main purpose in writing this passage? ______
    A. To introduce what is ETS.
    B. To tell the readers how to avoid ETS.
    C. To call for the action against ETS.
    D. To warn the readers against smoking.

    The marine environment is fascinating to study and work in due to its beauty, richness, and complexity. It covers three quarters of the surface of the Earth, yet we know more detail about the surface of Mars.
    In the past, it was seen as both an inexhaustible resource and a bottomless sink for our wastes. Yet the increasing pressures of overpopulation, pollution and the threat to our natural environment mean that there is an increasing need for scientists who can understand how it all works, how it affects us, and how we are affecting it from global warming through to the smallest plankton.
    From local issues to global concerns, we now know that the marine environment is inextricably linked to our lives, and to our future survival. It is an area where much remains to be discovered, and where only a multidisciplinary approach can cover the breadth of issues to be confronted. This is the approach taken on our Marine Environmental Science degree course.
    This course takes a multi-disciplinary approach to explore and understand the marine environment. After an initial grounding in basic science, optional choices are available in specialist topics such as marine ecosystems and pollution, coastal navigation and oceanography, among others.
    Our new harbor side marine laboratory is used for some of the specialist lectures, laboratory and project work, while a week's residential field course in the Isle of Man provides training to prepare for the research project conducted in your final year. There is an optional trip to Belize in the final year to study tropical marine environments.
    小题1: From the passage, we can infer that ______.
    A．people waste a lot of resource
    B．marine environment covers 3/4 of the surface of Mars
    C．marine environment is beautiful for its sufficient resources
    D．the Earth is similar to Mars
    小题2:The present environment of the Earth forces the experts and scholars to study ______.
    A．the relationship between people’s actions and natural environment
    B．the relationship between people’s actions and pollution
    C．the relationship between people’s actions and overpopulation
    D．the relationship between people’s actions and plankton
    小题3: According to the passage, a multi-disciplinary approach is effective because _______.
    A．we can choose some issues as optionally as we can
    B．we have practiced the approach for a long time
    C．the approach is linked to our future survival
    D．the approach covers a lot of problems we will meet
    小题4:We can divide the lectures of the course into ______ parts.
    A．1B．2 C．3D．4

    Technology has utterly transformed our ability to communicate with each other. Linking to each other both literally and figuratively, many of us connect through cell phones, email, instant messaging, blogs, and networking web sites, yet we may be less connected to each other than we think.
    According to a study, Americans are becoming increasingly socially isolated. The study reveals, for example, that one quarter of Americans say that they have no one to discuss important personal issues with, and that the number of close friends that American have has dropped from three to two. Meanwhile, the Boston Globe reports that this spreading isolation is experienced more sharply among those with less education, people of color, and older Americans. Unsurprisingly, those who are young, white, and well educated tend to have stronger social networks.
    From my own experience I have to say that I’ve never felt more connected, thanks to a web of friends, family, and colleagues. One of my closest friends is someone I met through an online discussion group who lives hundreds of miles away from me. We have met face-to-face only twice, yet our regular electronic correspondence and cell phone calls sustain our close friendship. And, speaking of blogging, my blog has introduced me to people I would never have met otherwise and has led to enduring and important friendships.
    On the other hand, I recently saw a scene unfold that proved to me how deeply disconnected we as Americans have become. I had just wrapped up a presentation on mediation at a family therapy(治疗) center. As I was leaving, I noticed a mother and her teenage son who had just completed their session with their family therapist(临床医学家). After making their next appointment, they both took out their cell phones, placed calls, and began loud conversations with whoever was on the other end. I walked out behind them to the parking lot to my car. They both jumped into their SUV, and, as I saw them drive off, they were still talking on their cell phones.
    But, alas, not to each other.
    51. What does the passage lead you to believe?
    A. Americans are more socially connected today.
    B. Americans are more socially isolated today.
    C. Technology plays a bigger role in American society.
    D. Americans don’t make good use of technology.
    52. Which of the following has nothing to do with the isolation among Americans?
    A. Age.              B. Education.                C. Skin color.               D. Sex.
    53. The author himself _______.
    A. has a wider range of friends because of technology
    B. has failed to take advantage of technology
    C. can only find true friendship through the Internet
    D. can’t make true friends in actual life
    54. What is true about the mother and son in the passage?
    A. They came for therapy in the same car.
    B. They were quite close to each other.
    C. There was not much communication between them.
    D. They preferred talking to each other on cell phones.
    55. The author probably feels ________ with the mother and son.
    A. puzzled         B. disappointed       C. amused                 D. surprised

    The Chinese have used a method called acupuncture to help perform operations for about 4,000 years without putting the patient to sleep. This involves inserting（插入）flexible needles （针）into certain parts of the body. The needles used are available in a number of stores in China and everyone may buy them.
    To learn how to use needle takes about one month of training. But to be skillful requires greater time. The person who performs the acupuncture knows how to insert the needles so the needles themselves are not painful. This person also knows where to place the needles so the patient feels no pain in the area where the operation is to be performed. The needles are not necessarily inserted near the place where the pain is to be prevented. In the past, a particular operation might require 25 or more needles placed in various parts of the body. But now this operation requires only 3 or 4 needles.
    Today the Chinese doctors are trying to learn more about acupuncture. They are trying to develop a convincing theory to explain how the needles work in preventing pain, or, why a needle in the wrist（手腕）, for example, would prevent the pain in the area of the mouth.
    A patient who needs an operation is given a choice between having acupuncture or having one of the chemicals used for putting him to sleep. It has been estimated that over half of the patients choose acupuncture because there is no sickness after the operation whereas（然而，反之） the chemical may make the patient sick for a few hours or a day.
    1．Acupuncture is a kind of _______.
    A. medical needles          B. medical equipment
    C. medical technique        D. medical examination
    2. To perform the acupuncture skillfully, one _______.
    A. has to learn how to insert the needles accurately in the right place
    B. should insert the needles where the pain is to be prevented
    C. needs to be trained for a short period of time
    D. must use fewer needles than in the past
    3. According to the 3rd paragraph, we can infer _______.
    A. people must insert a needle in the wrist to prevent the pain in the mouth
    B. people come to realize the shortcomings of the acupuncture
    C. people are convinced to use the acupuncture to cure diseases
    D. people need to make deeper research into the acupuncture
    4.Nowadays, more and more people prefer having acupuncture because _______.
    A. acupuncture has no side effects after the operation
    B. acupuncture costs them less than having chemicals
    C. chemicals usually cause many more deaths
    D. they want to protect the traditional Chinese medicine
    5. The author of the passage tends to be ________ acupuncture.
    A. strongly against      B. in favor of     C. doubtful about      D. uninterested in

    We may all have had the embarrassing moment: Getting half-way through a story only to realize that we’ve told this exact tale before, to the same person. Why do we make such memory mistakes?
    According to research published in Psychological Science, it may have to do with the way our brains process different types of memory.
    Researchers Nigel Gopie, of the Rotman Research Institute in Toronto, and Colin Macleod, of the University of Waterloo, divided memory into two kinds. The first was source memory, or the ability to keep track of where information is coming from. The second was destination memory, or the ability to recall who we have given information to.
    They found that source memory functions better than destination memory, in part because of the direction in which that information is travelling.
    To study the differences between source and destination memory, the researchers did an experiment on 60 university students, according to a New York Times report. The students were asked to associate (联想) 50 random ( 随意的) facts with the faces of 50 famous people. Half of the students "told" each fact to one of the faces, reading it aloud when the celebrity's (名人的) picture appeared on a computer screen. The other half read each fact silently and saw a different celebrity picture afterward.
    When later asked to recall which facts went with which faces, the students who were giving information out (destination memory) scored about 16 percent lower on memory performance compared with the students receiving information (source memory).
    The researchers concluded that out-going information was less associated with its environmental context （背景）---- that is, the person ---- than was incoming information.
    This makes sense given what is known about attention. A person who is giving information, even little facts, will devote some mental resources to thinking about what is being said. Because our attention is limited, we give less attention to the person we are giving information to.
    After a second experiment with another group of 40 students, the researchers concluded that self-focus is another factor that undermines destination memory.
    They asked half the students to continue giving out random information, while the other told things about themselves. This time around, those who were talking about themselves did 15 percent worse than those giving random information.
    "When you start telling these personal facts compared with non-self facts, suddenly destination memory goes down more, suggesting that it is the self-focus component ( 成分) that's reducing the memory, Gopie told Live Science.
    72. The point of this article is to ____.
    A. give advice on how to improve memory
    B. say what causes the memory to worsen
    C. explain why we repeat stories to those we've already told them to
    D. discuss the differences between source and destination memory
    73. What can we learn from the article?
    A. Source memory helps us remember who we have told the information to.
    B. One's limited attention is one of the reasons why those reading aloud to the celebrity's pictures perform worse on the memory test.
    C. Silent reading is a better way to remember information than reading aloud.
    D. It tends to be more difficult for people to link incoming information with its environmental context than outgoing information.
    74. The underlined word "undermines" probably means ____.
    A. weakens         B. benefits        C. explains        D. supports
    75. What did the scientists conclude from the second experiment?
    A. Destination memory is weaker than source memory.
    B. Focusing attention on oneself leads to relatively poor source memory performance.
    C. Associating personal experience with information helps people memorize better.
    D. Self-focus is responsible for giving information twice or more to the same person.

    Against the assumption that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
    This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
    This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
    Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧）levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
    “We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.
    小题1:According to the new findings, taking steps to prevent northern forest fires may _______.
    A．result in a warming climate
    B．cause the forest fires to occur more frequently
    C．lead to a longer fire season
    D．protect the forests and the environment there
    小题2:Earlier studies about northern forest fires ________.
    A．analyze all aspects of how northern fires influence climate
    B．indicate that forest fires will pollute the atmosphere
    C．suggest that people should take measures to protect environment
    D．suggest that the fires will speed up climate warming
    小题3:The underlined phrase “soaked up” in the last paragraph most probably means ________.
    A．releasedB．absorbedC．createdD．disturbed
    小题4: From the text we can draw a conclusion that forest fires in Alaska, Canada and Siberia may ______.
    A．warm the climate as the assumption goes
    B．allow more snow to reflect more sunlight into space and thus cool the climate
    C．destroy large areas of forests and pollute the far-off sea ice
    D．help to gain more energy rather than release more energy .
