    No country in the world has more daily newspapers than the USA.　There are almost 2000 of them，as compared with 180 in Japan，164 in Argentina and 111 in Britain.　The quality（质量） of some American papers is quite high and their views are used all over the world.　Excellent newspapers like the Washington Post or the New York Times　have a powerful influence（影响） all over　the country.　However，the Post　and the New York Times　are not national newspapers in the sense that The Times is in Britain of Le Monde is in France，since each American city has its own daily newspaper.　The best of these give detailed（详细的）accounts of national and international news，but many tend to limit themselves to state or city news.?

    Like the press（报刊） in most other countries，American newspapers report news from the “exciting” and “relaxing” to the serious.　They try to entertain people as well as give information，for they have to compete with the attraction of television.

    Just as American newspapers try to satisfy all tastes，they also try to attract readers of all political parties.　A few news papers support extremist（极端主义者） groups on the far right and on the far left，but most daily newspapers try their best to attract middle-of-the-road Americans who are mainly moderate（温和的）.Many of these papers print materials by well?known journalists of different political and social views，in order to give a balanced picture.?

    As in other countries American newspapers can be either responsible（负责任的） or irresponsible，but it is generally accepted that the American press serves its country well and that it has more than once exposed political scandals（丑闻），for example，the Watergate Affair（水门事件）.?

    1.Which newspaper in the U.　K.　is national？?

    A.?Le Monde.　　　　　　　 B.?Washington Post.?

    C.?New York Times.　　　　　　 D.?The Times.?

    2.Most American newspapers attract readers by carrying　　　　　 .?

    　　In the atmosphere, carbon dioxide acts rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from escaping．

    　　According to a weather expert' s prediction, the atmosphere will be 3℃warmer in the year 2050 than it is today, if man continues to burn fuels at the present rate．If this warming up took place, the ice caps in the poles would begin to melt, thus raising sea level several metres and severely flooding coastal cities．Also, the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere(北半球), possibly resulting in an alteration of the earth's chief food growing zones．

    　　In the past, concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet．But the weather experts are now paying more attention to West Antarctic, which may be affected by only a few degrees of warming, in other words, by a warming on the scale that will possibly take place in the next fifty years from the burning of fuels．

    　　Satellite pictures show that large areas of Antarctic ice are already disappearing．The evidence available suggests that a warming has taken place．This fits the theory that carbon dioxide warms the earth．

    　　However, most of the fuel is burnt in the northern hemisphere, where temperatures seem to be falling．Scientists conclude , therefore, that up to now natural influences on the weather have gone beyond those caused by man．The question is：Which natural cause has most effect on the weather?

    　　One possibility is the variable behavior of the sun．Astronomers at one research station have studied the hot spots and "cold" spots(that is, the relatively less hot spots)on the sun．As the sun rotates(使旋转), every 27.5 days, it presents hotter or "colder" faces to the earth, and different aspects to different parts of the earth．This seems to have a considerable effect on the distribution of the earth's atmospheric pressure, and consequently on wind circulation．The sun is also changeable over a long term：its heat output goes up and down in cycles, the latest trend being downward．

    　　Scientists are now finding shared relations between models of solar weather interactions and the actual climate over many thousands of years, including the last Ice Age．The problem is that the models are predicting that the world should be entering a new Ice Age and it is not．One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia(惯性)of the earth's climate．If this is right, the warming effect of carbon dioxide might thus be serving as a useful opposed balance to the sun's fading heat．

    (1)

    It can be concluded that a concentration of carbon dioxide in the atmosphere would ________．

    [　　]

    A．

    mean a warming-up in the Antarctic

    B．

    raise the temperature of the earth' s surface

    C．

    prevent the sun's rays from reaching the earth's surface

    D．

    explain the cause of great changes in the climate in the northern hemisphere

    (2)

    The article was written to explain ________．

    [　　]

    A．

    the greenhouse effect

    B．

    the solar effects on the earth

    C．

    the causes affecting weather

    D．

    the models of solar-weather interactions

    (3)

    Although the fuel consumption is greater in the northern hemisphere, temperatures there seem to be falling．This is ________．

    [　　]

    A．

    mainly because the levels of carbon dioxide are rising

    B．

    partly due to changes in the output of solar energy

    C．

    possibly because the ice caps in the poles are melting

    D．

    only due to the effect of the inertia of the earth' s climate

    (4)

    On the basis of their models, scientists believe the opinion that ________．

    [　　]

    A．

    the climate of the world should be becoming cooler

    B．

    the new Ice Age will be delayed by the greenhouse effect

    C．

    the man-made warming effect helps to increase the solar effects

    D．

    it will take thousands of years for the inertia of the earth's climate to take effect

    (5)

    If the assumption about the delay of a new Ice age is correct, ________．

    [　　]

    A．

    ice would soon cover the northern hemisphere

    B．

    the greenhouse effect could work in favor of the earth

    C．

    the best way to overcome the cooling effect would be to burn more fuels

    D．

    the increased levels of carbon dioxide in the atmosphere could warm up the earth even more quickly

    Banks are not ordinarily prepared to pay out all accounts(账，账户); they rely on depositors (储户) not to demand payment all at the same time. If depositors should come to fear that a bank is not safe, that it cannot pay off all its depositors, then that fear might cause all the depositors to appear on the same day. If they did, the bank could not pay all accounts. However, if they did not all appear at once, then there would always be enough money to pay those who wanted their money when they wanted it. Mrs. Elsie Vaught has told us of a terrifying bank run that she experienced. One day in December of 1925 several banks failed to open in a city where Mrs. Vaught lived. The other banks expected a run the next day, and so the officers of the bank in which Mrs Vaught worked as a teller had enough money on hand to pay off their depositors. The officers simply told the tellers to pay on demand. The next morning a crowd gathered in the bank and on the sidewalk outside. The length of the line made many think that the bank could not possibly pay off everyone. People began to push and then to fight for places near the tellers’ windows. The power of the panic atmosphere was such that two tellers, though they knew that the bank was quite all right and could pay all depositors, drew their own money from the bank. Mrs Vaught says that she had difficulty keeping herself from doing the same.

    1.A bank run happens when _______.

    　　 A. too many depositors try to draw out their money at one time　　

         B. a bank is closed for one or more days

    　   C. there is  enough money to pay all its depositors at one time

    　　 D. tellers of a bank take their own money from the bank　

    2.The tellers in Mrs. Vaught’s bank were told to ________.

    　　A. explain why they could not pay out all accounts

    　　B. pay out accounts as requested

    　　C. make the depositors believe that the bank was stand

    　　D. pay out money as slowly as possible

    3. According to the passage, the actions of the depositors of Mrs. Vaught’s bank were affected            mainly by the _______.

    　A.　ease with which they could get their money

    　B.　confidence  that Mrs. Vaught showed

    　C.　confidence shown by other depositors of the bank

    　D. failure of several other banks to open
