Question

One reaction to all the concern about tropical deforestation（毀林） is a blank stare that asks the question, "Since I don't live there, what does it have to do with me?"

The answer is that your way of life, wherever you live in the world, is tied to the tropics in many ways. If you live in a house, wash your hair, eat fruits and vegetables, drink soda, or drive a car, you can be certain that you are affected by the loss of tropical forests.

Biologically, we are losing the richest regions on earth when, each minute, a piece of tropical forest, the size of ten city blocks, disappears. As many as five million species of plants, animals, and insects (40 to 50 percent of all living things) live there, and are being lost faster than they can be found and described. Their loss is immeasurable.

Take rubber for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough. Today over half the world's commercial rubber is produced in Malaysia and Indonesia, while the Amazon's rubber industry produces much of the world's four million tons. And rubber is an important material in making gloves, balloons, footwear and many sporting goods. Thousands of other tropical plants are valuable for their industrial use.

Many scientists strongly believe that deforestation contributes to the greenhouse effect -- or heating of the earth from increased carbon dioxide in the atmosphere. As we destroy forests, we lose their ability to change carbon dioxide into oxygen.

Carbon dioxide levels could double within the next half-century, warming the earth by as much as 4.5 degrees. The result? A partial melt-down of polar ice caps, raising sea levels as much as 24 feet; even 15 feet could threaten anyone living within 35 miles of the coast. Unbelievable? Maybe. But scientists warn that by the time we realise the severe effects of tropical deforestation, it will be 20 years too late.

Can tropical deforestation affect our everyday lives? Now, you should have got the answer.

1.The underlined word "synthetics" probably means_________.

A. natural rubber                   B. tropical materials

2.According to the passage, which of the following is NOT true?

A. The forests are losing their function in turning carbon dioxide into oxygen.

B. Many of our daily uses are related to the tropical forests.

C. Tropical plants can be used to make industrial products.

D. High carbon dioxide levels will make the earth warmer.

3.The author's attitude towards the tropical deforestation is _________ .

A. puzzling        B. cold          C. supporting        D. opposed

4.Which of the following might be the best title for the passage?

A. Tropical Forests                 B. The Value of Tropical Forests

C. Tropical Forests and Our Life     D. The Greenhouse Effects

 

Answer 1

【答案】

 

1.C

2.A

3.D

4.C

【解析】

試題分析：本文主要講述的是熱帶雨林對環(huán)境的諸多好處，同時也說明了熱帶雨林的失去對環(huán)境會帶來很多的傷害。

1.C推理題。根據Take rubber for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough.可知這里的. Synthetics應該是與前面的natural rubber是相反的意思，指非自然的人造材料。故C項正確。

2.A 推理題。文章中提及了失去了熱帶雨林，我們就會失去把二氧化碳轉換成氧氣的物體，而不是說森林失去把二氧化碳轉換成氧氣的的能力。故A想說法是錯誤的。其余三項在文章中都有涉及。

3.D 推理題。作者在文章中多次提及了失去熱帶雨林對我們的環(huán)境的巨大影響，說明他對破壞雨林是持反對態(tài)度的。故D正確。

4.C 主旨大意題。本文主要講述的是熱帶雨林對環(huán)境的諸多好處，同時也說明了熱帶雨林的失去對環(huán)境會帶來很多的傷害。故C正確。
