题目内容

14．我想知道你的外套是不是要洗一下．
I wonderwhether your coat needs washing．

分析 whether your coat needs washing．

解答答案：whether your coat needs washing．这里是主从复合句，作为wonder的宾语从句，引导词是whether，后加陈述语序，主语是your coat，主句是一般现在时，从句时态不受限制，这里是说是否需要，用一般现在时，主语是三单，故用needs需要，need doing sth主动的形式表示被动，故wash洗的动名词是washing，故答案是whether your coat needs washing．

点评宾语从句的三要素是引导词，时态和语序．还要注意need doing sth的用法．

根据表格信息，从每小题的A、B、C、D中选出最佳答案。

The earth is 4 600 million years old. We humans have lived on earth for only 35 000 years, but during this period we have changed our planet a lot in many ways. Some things we’ve done are very good for the earth while some are bad.

All over the world, people have cut down millions of trees. When it rains or when the wind blows, the earth is taken away. Forests have become deserts, so more and more sorts of animals and plants are disappearing.

In big cities, cars and buses have polluted the air. Many people in cities now have health problems.

Factories have also polluted the land and the water. As a result, many rivers and lakes are nowdead.

Around the earth, there’s a special kind of oxygen called “ozone”(O3). It is important to theearth. But now air pollution is destroying it and that has made a very big hole in the ozone layer. Too much harmful radiation from the sun passes through the hole and reaches the earth directly. This is very dangerous because this kind of radiation can cause cancer.

Carbon dioxide (CO2) in the air has increased a lot. It mainly comes from burning oil, coal andwood. This has formed a “blanket” around the earth. The heat from the sun can’t escape so thetemperature is rising. This is called “the greenhouse effect”. It causes the level of the oceans to rise and the climate of the earth to change.

All these problems are very serious, so we must do something now.
