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 industries areas
解析：事实细节题。根据文中第一句，以前人们都认为空气污染只会影响那些有众多工厂和严重交通堵塞现象的大城市及其周边地区，所以选D。根据下文，A、B、C都是后来人们意识到的。
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：推理判断题。根据文章第一段最后两句，作者引用了一些科学家的观点，空气中二氧化碳的增多会导致温室效应。然后作者提出一种假设，如果这是真的的话，那么南极的冰雪就会融化，将纽约等城市淹没。然而对这种观点的正确性从文章很难看出。另外文中第二段第三句提到“今天我们还不能确定这两种情况能否发生……”，所以作者的态度应是“uncertain”。
3.The word \\(B)
A. slip into
B. make up for
C. set up
D. catch up with
解析：推理判断题。即使不认识“offset”这个词，我们也可通过上下文猜出来。文章提到的两种可能性一是全球变暖，一是全球降温，只有这两种可能性相互抵消，即冷暖相互弥补，才能出现最后一句的“气温和现在一样正常”。所以选B（make up for“弥补”）。slip into“滑进”；set up“建立，创造”；catch up with“追上，赶上”。
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：推理判断题。文章第二段第二句提到降温几度就能导致农业生产困难甚至无法生产，这对农业来说无疑是巨大的灾难，所以B正确；根据第一段，温室效应可能导致南极的冰雪融化，将纽约等城市淹没，所以A（全球变暖不会给地球生活带来危害）是不正确的；根据常识，近几十年气温在逐渐升高，所以C也不对；作者在文中提到空气污染严重影响全球气温的变化，所以只要污染存在，气温就不可能恒定不变，D说得太绝对了。
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：归纳概括题。文章第一段提到地球的气温可能受到空气污染的影响，接下来谈到两种因空气污染可能造成的后果，所以应选C“空气污染可能带来的影响”。其他三个选项都只是文章主题的一个方面。

6.Before the publication of the book \\(C)
A. Harriet knew that it would be a great success
B. the publisher wanted Harriet to publish it at her own expense
C. nobody knew that it would become a very popular book

解析：事实细节题。从文章第一段可知，在《汤姆叔叔的小屋》出版前没有人知道这本书能成功。
