题目内容

10．-Whose iPhone 6+is it？
I'm looking for it here and there．（　　）

A．

B．

C．

Mine

D．

Myself

分析 --这是谁的iPhone6plus？
--我的．我正到处找它呢．

解答答案：C 根据Whose iPhone 6+is it？可知，此处询问物品的归属，所缺含义应为"我的"，即物主代词．又知物主代词分为形容词性物主代词和名词性物主代词，且形容词性物主代词与名词连用不能单独使用，名词性物主代词可单独使用，所以此处应使用mine，故选C．

点评此题考查物主代词的用法，做题时，先根据题干判断出表示物品归属，即使用物主代词，再根据已有的知识储备可知，形容词性物主代词必须后接名词，名词性物主代词可单独使用，结合选项选出符合题意和用法的答案．

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.
