4、hy where when how连接词的作用：只起_作用，在主语从句中_。连接代词的作用：起连接作用，在主语从句中充当_ _ _、定语，本身有实在意义。连接副词的作用：起连接作用，在主语从句中充当_，可分别充当地点、原因、时间、方式等状语，本身有实在意义。What we need now is time and money. 我们所需要的是时间和资金。解析：what we need在该复合句中充当主语，是主语从句；由连接代词what 引导 ，what在主语从句中充当动词need 的宾语。 Who and what you are is not important. What is impor

5、tant is how you will finish this task. 你是谁，是干什么的都不重要，重要的是你会怎样来完成此项任务。 解析：who and what you are 在前一个复合句中充当主语，是主语从句。由连接代词who 和what 引导，who 和what 在主语从句中充当表语。What is important 在后一个复合句中充当主语，是主语从句； 由连接代词what 引导，what 在主语从句中充当主语。how you will finish this task 在该复合句中充当表语，是表语从句。由连接副词how引导，在表语从句中充当方式状语。When the e

6、arth came into being is still a mystery to us. 地球是何时形成的对与我们来说仍是个谜。 解析：When the earth came into being 在该复合句中充当主语，是主语从句，由连接副词when 引导，when 在主语从句中充当时间状语。It is very important and necessary that young people should learn English well.年轻人学好英语是很重要也很必要的。解析：it 是形式主语，真正的主语是that young people should learn Englis

7、h well ,因此该从句是主语从句。由连接词that 引导，在主语从句中不充当任何成分，只起连接作用。连接词that 本身没有意义，但不能够被省略。II 几组连接词的辨析1. what /that相同点：都起连接作用，都可用来引导名词性从句。不同点：what 是连接代词，在从句中充当主语、宾语、表语，本身有实在意义，译为“的” that 是连接词，在从句中不充当任何成分，本身没有任何意义; that也可用作关系代词，引导定语从句，在定语从句中充当主语、宾语、表语2. who/whom相同点：都指人，可用来引导名词性从句，也可用来引导定语从句，在从句中充当宾语。不同点：who 在从句中可以充当

8、主语，宾语，表语. whom 在从句中只能充当宾语 _ he is matters little. What matters most is what he is. 他是谁无关紧要，有关系的是他是做什么的。3. who/which相同点：在名词性从句中，都可以指人，在从句中充当主语，宾语。不同点：which 指人时，必须是在特定范围之中：“中的哪一个”_ of you will offer to help that old lady cross the street?你们当中谁愿意帮助老奶奶过马路？_will be sent there to work with you is not deci

9、ded yet. _ of us will be sent there to work with you is not decided yet.谁会派去与你工作还没就定下来呢，4. who/whoever相同点：在名词性从句中都可用来指人，充当主语，表语，宾语不同点：who 可引导各种名词性从句；whoever则常只用来引导主语从句或宾语从句 Whoever 侧重“无论谁”，表示单数，泛指，用来加强语气。Who 还可用来引导定语从句；whoever 可用来引导状语从句。_breaks the law shall be punished. 无论谁触犯法律，都将受到惩罚。 This prize w

10、ill be given to_ gets the highest mark in this test.此项奖将颁发给本次考试获得分数最高之人。5. whether/if相同点：二者拥有相同含义：“是否”，都可以用来引导动词的宾语从句。不同点：whether 可以用来引导其他名词性从句，还可以引导让步状语从句，“无论还是” If 可以引导条件状语从句; Whether 可以用来引导介词宾语从句； 可以其后跟动词不定式。_he will be allowed to work here depends on how he acts in the interview.他是否能够在此工作取决于他在面试

11、中的表现。6. what/which相同点： 二者都可用来引导名词性从句，都可以用来指物不同点：what 表示泛指，当从句中缺少主语，宾语或表语，而且可翻译为“的”时，就使用what，只能指物。只能引导名词性从句。which表示特指，指在一特定范围中的“哪一个”可指人，也可指物。此外，which 可以用作关系代词，指物，在定语从句中充当主语、宾语、表语。_school you will choose to study in means nothing to me.你选择在哪所学校就读我并不关心。三、课后自测（一）基础知识自测 I. 单词拼写1.

25、eans less corn is left to feed animals and people, which drives up the cost of food.

Finally, over many yea

26、rs, the energy benefit from burning ethanol would make up for the forest loss. But by then, climate change would have progressed so far that it might not help.You cannot really declare any practice “sustainable” until you have done a complete lift-cycle analysis of its environmental（环境的）costs. Even
