    考研英语阅读理解第十七篇（后附习题和答案）
   
    A mysteriousblack cloudapproaches the earth-our planet's weather is
severely affected.
    Throughout the rest of June and July temperatures rose steadily all over
the Earth. In the British isles the temperature climbed through the eighties,
into the nineties, and moved towards the hundred mark. People complained, but
there was no serious disaster.
    The death number in the U. S. Remained quite small, thanks largely to the
air-conditioning units that had been fitted during previous years and months.
Temperatures rose to the limit of human endurance throughout the whole country
and people were obliged to remain indoors for weeks on end. Occasionally
air-conditioning units failed and it was then that fatalities occurred.
    Conditions were utterly desperate throughout the tropics(热带地区)as may be
judged from the fact that 7943 species of plants and animals became totally
extinct. The survival of　Man himself was only possible because of the caves and
cellars(地窖)he was able to dig. Nothing could be done to reduce the hot air
temperature. More than seven hundred million persons are known to have lost
their lives.
    Eventually the temperature of the surface waters of the sea rose, not so
fast as the air temperature it is true, but fast enough to produce a dangerous
increase of humidity(湿度). It was indeed this increase that produced the
disastrous conditions just remarked. Millions of people between the latitudes of
Cairo and the Cape of Good Hope were subjected to a choking atmosphere that grew
damper and hotter from day to day. All human movement ceased. There was nothing
to be done but to lie breathing quickly as a dog does in hot weather.
    By the fourth week of July conditions in the tropics lay balanced between
life and total death. Then quite suddenly rain clouds appeared over the whole
globe. The temperature declined a little, due no doubt to the clouds reflecting
more of the Sun's radiation back into space, But conditions could not be said to
have improved. Warm rain fell everywhere, even as far north as Iceland. The
insect population increased enormously, since the burning hot atmosphere was as
favorable to them as it was unfavorable to Man many other animals.
    81. In the British Isles the temperature        　.
    A)stayed at eighty
    B)ranged from eighty to ninety

    C)the government had taken effective measures to reduce the hot
temperature
    D)people were provided with the most comfortable air-conditioners
    83. Millions of people in Cairo(开罗)and the Cape of Good Hope(好望角)were
subjected to a choking atmosphere because        　.
    A)the temperature grew extremely hot
    B)the temperature became damper and hotter as the humidity of the surface
waters of the sea increased
    C)their conditions were too dangerous
    D)nothing could be done with the hot temperature
    84. By the fourth week of July conditions in the tropics were such
that        　.
    A)human survival would be impossible
    B)more and more people would lose their lives
    C)fewer people could be saved
    D)survival or death was still undecided
    85. The insect population increased due to        　.
    A)the hot air
    B) the tropical climate
    C)the rain clouds
    D)the damp atmosphere
