There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a \\
1.As pointed out at the beginning of the passage, people used to think that air pollution______.(D)
A. caused widespread damage in the countryside
B. affected the entire eastern half of the United States
C. had damaging effect on health
D. existed merely in urban and industrial areas
解析：细节题。根据文章第一段第一句可知，以前人们认为，空气污染仅仅影响紧靠着有工厂或交通拥挤的大城市的地区，选项D(只存在于城市和工业区)正确。选项A(在农村造成大面积的损害)文中未提及。根据第一段第三句可知，重污染天气曾多次笼罩美国东部农村，选项B(影响美国东半部地区)范围过大且与题干不符。选项C(损害健康)与题于不符。故本题选D。
2.As to the greenhouse effect, the author(B)
A. shares the same view with the scientists
B. is uncertain of its occurrence
C. rejects it as being ungrounded
D. thinks that it will destroy the world soon
解析：细节题。文章第一段第五句和第二段第一句分别陈述了两种观点，根据第二段第三句可知，现在我们也无法确定会发生哪种情况，选项B(不确定会不会发生)正确。选项A(与科学家观点一致)和选项D(认为温室效应很快会摧毁世界)文章中并未提及。选项C(因为不切实际而反对)与文章不符，文中作者并未表现出反对的态度。故本题选B。
3.The word \\(B)
A. slip into
B. make up for
C. set up
D. catch up with
解析：推理题。文章提到了两种趋势，即地球温度上升和地球温度下降。offset所在句意为“如果我们足够幸运，也许这两种趋势将相互offset，全球温度不变”。由“全球温度不变”可知，这两种趋势只有相互抵消，才能保持气温不变，故offset在这里是“抵消”的意思。选项A(进入，滑入)、选项C(建立，设立)、选项D(赶上，追赶)均没有“相互抵消”的意思。选项B(弥补，补充)与“抵消”意思相近，故本题选B。
4.It can be concluded that______.(B)
A. raising the world’ s temperature only a few degrees would not do much harm to life on earth
B. lowering the world’ s temperature merely a few degrees would lead many major farming areas to disaster
C. almost no temperature variations have occurred over the past decade
D. the world’ s temperature will remain constant in the years to come
解析：推理题。根据文章第一段最后一句可知，全球温度只增加几度就会引起极地的大部分冰帽融化，导致有些城市被淹没，选项A(温度只增加几度不会对地球上的生命产生危害)错误。根据第二段第二句可知，全球温度只下降几度就可能带来一个新的冰河时代，许多高海拔区域的农业生产将很难或无法开展，选项B(温度只下降几度会给许多主要农业区域带来灾难)正确。选项C(在过去十年里气温几乎没有变化)文中未提及。根据第二段最后一句可知，如果我们足够幸运，也许这两种趋势将相互抵消，全球温度不变。这只是一种猜测的情况，故选项D(未来几年全球温度将保持不变)错误。故本题选B。
5.This passage is primarily about______.(C)
A. the greenhouse effect
B. the burning of fossil fuels
C. the potential effect of air pollution
D. the likelihood of a new ice age
解析：主旨题。第一段的前三句提出空气污染的全球性，后三句提出空气污染可能带来的一种后果。第二段前两句指出空气污染可能带来的第二种结果，后两句指出这两种结果发生的不确定性及对将来的美好愿望。由此可知，文章主要论述了空气污染的普遍性及其影响，选项C(空气污染的潜在影响)正确。选项A(温室效应)和选项D(新冰河时代的可能性)只是两种可能性结果。选项B(化石燃料的燃烧)是引起温室效应的原因。故本题选C。
It is difficult to imagine what life would be like without memory. The meanings of thousands of everyday perceptions, the bases for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory.
Memory can be defined as the capacity to ke
