A．

play

B．

分析 --我们的老师放学后经常和我们一起做游戏．--你们的老师真好！

解答答案：D 英语中表示经常做某事，要用一般现在时，这里句子的主语our teacher with us中，介词词组with us是用来修饰说明主语情况的，只表示伴随，不表示并列．因此主语our teacher为第三人称单数，动词用三单形式，故选：D．

点评考查一般现在时，理解句子的意思，注意动词三单形式的变化．

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.
