A greenhouse is a building made of glass which is used for keeping plants warm when the outside temperature is low. In a similar way there are several gases in the atmosphere 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 the 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.
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 forests. The rapid increase in the 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 in the atmosphere doubles there will be a rise in the earth’s temperature of between 1 and 4. This may seem a small increase, 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, these gases have greatly increased.
Suppose the earth’s temperature rose by 3 degrees______.
选项
A、great harm would be done to humankind
B、the sea level would go up by 10 centimeters
C、all the land in the world would be flooded
D、crops would be unable to grow on the earth
答案
A
解析
根据第二段第六行This may seem a small increase,but it would be enough to causemajor changes in geography and agriculture.可知温度上小小地上升3度可能会给地理以及农业带来很大的影响,故A正确。C、D过于绝对,根据第二段倒数第五行最后Large areas of theworld would be flooded,and some areas would become dry and unable to produce crops.可知这两项是错的。B错误,根据第二段第三行最后The world’s temperature has already gone up by half adegree this cenrury,and the sea level has risen by 10 centimeters。
