题目内容

11．She ______ to give a talk about how to save water yesterday．（　　）

A．

invite

B．

invited

C．

is invited

D．

was invited

分析昨天，她被邀请做一个关于如何节约用水的报告．

解答答案：D 根据She ______ to give a talk about how to save water yesterday．可知这句话的主语是She，是动作的承受者，它和动词invite构成被动关系，所以应该用被动语态．根据时间状语yesterday．可知应该用一般过去时的被动语态．一般过去时的被动语态的构成：was/were+及物动词的过去分词．主语是she，所以应该是was invited，故选：D．

点评主要考查被动语态，当句子的主语是动作的承受者时，应该用被动语态，本题考查的是一般过去时态的被动语态．一定注意其构成形式，一般过去时的被动语态的构成：was/were+及物动词的过去分词．

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.
