D
  In the atmosphere,carbon dioxide actd 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 excaping.
  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 luels 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 meters and severely flooding coastal cities.Also,the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere(半球),psooicbly resulting in an alteration of 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 a warming on the scale that will possibly take place in the next fifty years from on burning of fuels.
  Satellite pictures showthat 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 exceeded 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(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 variable over a long term:its heat output goes up and down in cycles,the latest trend being downward.
  Scientists are now finding mutual 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(不活动,惰性) of the earth's climate.If this is right,the warming effect of carbon dioxide might thus be serving as a useful counter balance to the sun's diminishing heat.
  68.It can be concluded that a concentration of carbon dioxide in the atmosphere would ___.
   A.mean a warming - up im the Arctic
   B.raise the temperature of the earth's surface
   C.prevent the sun's rays from reaching the earth's surface
   D.account for great changes in the climate in the northern hemiphere
  69.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 variations in the output of solar energy
   C.possibly because the ice caps in the poles are melting
   D.exclusively due to the effect of the inertia of the earth's climate
  70.On the basis of their models,scientists are of 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

           When sailors are allowed ashore (登岸) after a long time at sea, they sometimes get drunk and cause trouble. 1 this reason, the navy (海军) 2 has its police in big ports. 3 sailors cause trouble, the police come and      4them.

           One day, the police in a big seaport received a telephone call 5 a bar(酒吧)in the town. The barman said that a big sailor had got drunk and      6 the furniture in the bar. The officer 7 the police guard that     evening said that he 8 immediately.                   

       Now, officers who 9 and punish the sailors who were      10 drunk usually choose 11 policeman they could find to go with them.      12 this particular officer did not do this. Instead, he chose the smallest and 13 man he could find to go to the bar with him and 14 the sailor.   Another officer who      15 there was surprised when he saw the officer of the guard choose      16 small man. 17 he said to him. "Why 18 you take     a big man with you? You have to fight the sailor who 19."    

                   

       "Yes, you are 20 right," answered the officer of the guard. "That is exactly      21 I 22 this small man. If you saw two policemen coming      23 you, and one of them was 24 the other, which one      25 you attack(攻击)?"

     When you read a story in English, do you read it for the story or   for the English? This is a 1 that is not so foolish 2 it may seem. For   I 3 that many students of English 4 far more attention to the story   than to the English. They read and 5 and for a long time 6 remember   the story, but do not care to study the 7 of words and 8 in it. For   instance, they care for the memory of 9 the mystery (神秘) in the   story is solved, but do not remember a 10 sentence in the story and   cannot 11 what preposition is used before or after a certain 12 in   the speech of a 13 character.

           

   Of course, it is all right to read and enjoy and 14 a story, and   so 15 as one wants to 16 the story only, one need not bother (费心)   about the language. But the case is quite different with a 17 of   English. I mean a student of English is different from a student of   stories or 18 is called the general reader.

           

   As you may also have 19 from the above, you ought to read very 20.   Not only very carefully but also aloud, and that again and again 21   you know the passage by heart and can 22 it as if it were your own.   Positively (正面) this will teach you many 23 words and phrases;   negatively (负面) it will help you to avoid many errors and faults in   expression. Incidentally I have found from 24 that intelligent   copying is a help to 25 by heart.
