Today, we know that although these are the areas with the worst air pollution, the problem is actually worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel 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”holding in heat reflected from the earth and raising the worlds average temperature. If this view is correct and the worlds 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 under water. Another view, less widely held, is that increasing particulate(微粒、颗粒)matter in the atmosphere is blocking sunlight and lowering the earths temperaturea result that would be equally disastrous. A drop of just a few degrees could create something close to new ice age and would make agriculture difficult or impossible in many of our top farming areas. At present we do not know for sure that either of these conditions will happen(though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we are very lucky, the two tendencies will offset each other and the worlds temperature will stay about the same as it is now. 【语篇概述】本文阐述了大气污染可能导致的两种结果。1. As pointed out at the beginning of the passage, people used to think that air pollution. A. caused widespread damage in the countrysideB. affected the entire eastern half of the United StatesC. had damaging effects on healthD. existed merely in urban and industrial areas【解析】选D。细节理解题。由文章开头可知。过去人们认为空气污染主要存在于大城市中。2. As far as the greenhouse effect is concerned, the author. A. shares the same view with the scientistsB. is uncertain of its occurrenceC. rejects it as being ungroundedD. thinks that it will destroy the world soon【解析】选B。推理判断题。文章第一段论述了温室效应可能会使全球气温上升, 第二段又谈到污染也可能会使大气温度下降, 根据“At present we do not know for sure that either of these conditions will happen. . . ”可知B项正确。3. It can be inferred from the passage that. A. lowering the worlds temperature merely a fewdegrees would lead many major farming areas to disasterB. raising the worlds temperature only a few degrees would not do much harm to life on earthC. almost no temperature variations have occurred over the past decadeD. the worlds temperature will remain constant in the years to come【解析】选A。细节理解题。由第二段中的第二句可知A项正确。其他几项均不符合文中所列事实。4. This passage is mainly concerned with. A. the greenhouse effectB. the burning of fossil fuelsC. the potential effect of air pollutionD. the likelihood(可能性)of a new ice age【解析】选C。主旨大意题。文章阐述了大气污染可能导致的两种结果: 升温和降温。所以只有C项正确。. 语法填空阅读下面材料, 在空白处填入适当的内容(1个单词)或括号内单词的正确形式。Earthquakes are something that people fear.

Do you still remember the day_ which we met for the first time? He lost the book_ which he kept many telephone numbers. 答案：toonin10. 【解析】that。考查名词性从句的引导词。引导一个表陈述的表语从句, 故用that。关闭Word文档返回原板块精品 Word 可修改 欢迎下载
