Question

In the past, man did not have to think about protection of the environment. There were very few people on the earth, and natural resources seemed to be unlimited.

Today things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue to do this, human life on the earth will not survive.

Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on land. Yet, we continue to use more powerful machines to cut down more and more trees.

We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste is still put into rivers, but there are few laws to stop this.

We also know that if the population of the countries in the world is to rise at the present rate in a few years, there will not be enough food.

What can we do to solve these problems?

If we eat more vegetables and less meat, there will be more food available for everyone. Land that is used to grow crops can feed five times more people than land where animals are kept.

Our natural resources will last longer if we learn to recycle them.

The world population will not rise so quickly if people use modern methods of birth control.

Finally, if all of us think about the problem, we will have a better and cleaner planet in the future.

【解析】

試題分析：本文敘述了過去，人們不必擔心保護環境的問題。 因為那時地球上人口稀少，自然資源似乎取之不盡。而現在世界變得擁擠異常。我們正在耗盡我們的自然資源，有毒化學制品的使用也正污染著環境。如果我們繼續這樣下去，地球上的生命將不復存在。

1.主旨大意題。全文敘述了我們面臨的環境問題要想出方法來拯救自己的星球的環境，故選A。

2.細節理解題。根據If we eat more vegetables and less meat, there will be more food available for everyone. 如果我們吃更多的蔬菜，并不是節省了食物，而是對于大家來說有更多的可使用的食物，故選A。

3.推理判斷題。根據If we continue to do this, human life on the earth will not survive.可推知如果人類不能解決環境這一問題，人類就等于毀了自己。故選B。

4.細節理解題。根據We are using up our natural resources too quickly, 世界的自然資源正在被利用地很快，故選D。
