题目内容

4．-Why are you so worried，Mrs．Green？
-I have lost the scarf _______ my daughter bought me on my birthday．（　　）
A．whomB．whoC．whoseD．which

分析 --格林夫人，你为什么很着急呢？
--我把女儿在我生日的时候给我买的丝巾丢了．

解答 答案：D．
whom意思是"谁"修饰人，作宾语；who意思是"谁"修饰人，作主语；whose意思是"谁的"某人的或某物的，作定语；which意思是"哪一个"指物，作主语或宾语；根据"the scarf_______ my daughter bought me"先行词是scarf丝巾，在定语从句中需要一个可以作宾语的引导词来指物，故选D．

点评 首先要掌握这几个关系代词的意思以及用法，然后结合具体的题目，就可以确定正确答案．

13．The earth is 4，600 million years old．We humans have lived on the earth for only 35，000 years，but during this period we have changed our planet a lot in many ways．Some things we're done are evey good for the earth while some are bad．
    Fewer trees   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．
    Traffic and factory pollution    In big cities，cars and buses have polluted the air．Now many people in cities have health proplems．Factories have also polluted the land and the water．As a result，many rivers and lakes are now dead．
    The ozone layer （臭氧层）    Around the earth，there's a special kind of oxygen（O2）called"oaone"（O3）．It is important to the earth．But now air pollution is destroying it and that has made a very big hole in the ozone layer．Too much harmful radiation（辐射）from the sun passes though the hole and reaches the earth directly．This is very dangerous because it can cause cancer．
     More carbon dioxide （CO2） Carbon dioxide in the air has increased a lot．It mainly comes from burning oil，coal and wood．This has formed a"blanket"around the each．The heat from the sun can't eacape so the temperature is rising．This is called"the greenhouse effect（温室效应）"．It causes the level of the ocean to rise and the climate（气候）of the earth to change．
    All these problems are very serious，so we must do something now．
