2、成分。That 只起连接作用，不充当任何成分。1._ he wants is a book.2. _ he wants to go there is obvious.3.The result is _ we won the game.4.This is _ we want to know.5.Is _ he told us true ?6.We should pay attention to _ the teacher is saying.7. I have no doubt _ he will come.8. I have no idea _ he did that afternoon.(二

3、） if 和whether 的选用不能使用if 的情况：a. 主语从句b. 表语从句c. 同位语从句 d. 介词后的宾语从句e. whether to do 做动词宾语不能用if to do.f .whether or not 连在一起引导宾语从句时不用if.1.

7、uggestion, advice等.3.连接词通常是that,也可根据含义选用 whether, what, when, where 等来引导同位语从句.1. I have no idea _ he comes from.2. He cant answer the question _ he got the money.3.He gave us many suggestions _ we should get up earlier and take more exercise.4.I have no doubt _ he will win.5. I have some doubt _ he

8、will win.（六） 同位语从句和定语从句的区别1.定语从句是先行词的修饰语，它不涉及先行词的具体内容。定语从句中that起连接作用，在定语从句中充当一个句子成分，充当从句的宾语成分时可省略。2.同位语从句对中 心词的内容作进一步的解释和说明，表明中心词的具体内容。引导同位语从句的that 在同位语从句中不做任何成分,只起连接作用,无具体含义,且不可省略.1.We expressed the hope that they had expressed.2.

Please tell me _.(九）名词性从句中一律使用陈序语气。e.g. He asked how much I paid for the violin.I want to know what he has told you. 我想知道他告诉了你什么。 Sh

12、e always thinks of how she can work well. 她总是在想怎样能把工作做好。(十) 疑问词+ever 与no matter + 疑问词的区别：疑问词+ever可以引导_或_ .Whoever breakes the law must be punished . 或：Whoever breakes the law, he must be punished . no matter + 疑问词只能引导_.No matter who breaks the law, he must be punished.
