[1] A green house is a building made of glass which is used to keep warm when the outside temperature is low. In a similar way there are several gases in the atmosphere (mixture of gases that surrounds the earth) which trap the heat produced by the sun and prevent it from escaping. These gases are known as “greenhouse gases”, and the way in which they trap heat in the atmosphere is called the “greenhouse effect”. This is not simply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us.

[2] The problem is that in the last century and a half, we have been putting too many of these gases into the earth’s atmosphere by burning large quantities of coal and oil and by cutting down forest. The rapid increasing in greenhouse gases is making the world warmer. The world’s temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimeters. If the amount of carbon dioxide(二氧化碳) in the atmosphere doubles, there will probably be a rise in the earth’s temperature of between 1 and 4℃. This____________________, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased.

5.1960s.

【解析】

試題分析：【文章大意】本文是一篇說明文。文章講述了什么是溫室效應(yīng)及其變化。還介紹了這種變化對人類造成的影響。

1.The concept and change of greenhouse effect/What is greenhouse effect and change of it.  考查文章的主旨大意。文章前半部分These gases are known as “greenhouse gases”, and the way in which they trap heat in the atmosphere is called the “greenhouse effect”.闡述了什么是溫室效應(yīng)后部分it would be enough to cause major changes in geography and agriculture闡述溫室效應(yīng)的其變化。

2.It is a natural course that is to a certain degree useful to us 考查信息查找。根據(jù)文章第一段中的In other words, the greenhouse effect is a natural course which is to some degree helpful to us.可知答案。

3.Because human put gases into the atmosphere by burning large quantities of coal and oil and by cutting down forest. 根據(jù)文章第二段中的The problem is that in the last century and a half, we have been putting too many of these gases into the earth’s atmosphere by burning large quantities of coal and oil and by cutting down forest.可知答案。

4.may seem a small increase 根據(jù)文章第二段中的there will probably be a rise in the earth’s temperature of between 1 and 4℃可知，溫度從1---4度，變化的小的。

5.1960s.考查指代的用法。根據(jù)最后一句This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased.可知，then指1960s。
