第一节任务型阅读（共10小题；每小题1分）
阅读下列短文，根据所读的内容在文章后的表格中填入恰当的单词。注意表格中的每个空格只填1个单词。
Global warming is one of the major environmental problems we are facing today. Scientists think a further rise in the carbon dioxide levels will make this situation worse. The greenhouse effect causes the earth’s heat to be trapped in the atmosphere, which results in the increase in temperature. This in turn has an effect on various plants and animals. Global warming makes it difficult for some of them to survive.
Ozone depletion(臭氧耗损) means a drop in the quantity of the ozone in the earth’s stratosphere (平流层). The ozone hole in the Antarctic is mainly due to the release of CFCs ( a type of gas). Because of ozone depletion, humans are facing various problems such as the harmful effects of UV rays.
Water pollution is caused when wastes are thrown into water. What’s more, many harmful chemicals are also put into water, which causes the deaths of many wild animals and endangers the health of humans.
The increasing population is causing a loss of natural resources. This is related to various human activities. For example, overfishing has caused many kinds of fishes to die out. Forests are being cleared to meet the rising demand for paper, wood, even for land. Mining(采矿) has led to a further drop in mineral resources. If we used up all the resources, how could our children survive on this planet?
These are some of the current environmental problems we are facing today. Only with an effort from each person, can we hope to save our planet from being destroyed.
