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. (76) 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 "greenhouse effect"--conserving heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.
(77) Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth’s temperature--a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top fanning areas. Today we do not know for sure that either of these conditions will happen (though one recent government report drafted by exports in the field concluded that the greenhouse effect is very possible). Perhaps, if we are lucky enough, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now.
The word "offset" in the second paragraph could be replaced by _________.
选项
A、slip into
B、make up for
C、set up
D、catch up with
答案
B
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“迫上,赶上”。
