上图体现：状语从句，定语从句，主语从句，宾语从句,同位语的关系与区别。

名词性从句：定义

The question why the earth moves around the sun has not been answered yet. The idea that we should take a day off was put forward by Tom. 总结：

连接词：that 不做成分，没有意思

Whether/if 不做成分，有意思“是否”

What/who/which/whom/ whose /whatever/whoever/ whichever/whomever/ 做成分，（主语，宾语，表语，定语）；有意思 When/why/where/how/whenever/however/wherever 做成分（状语），有意思

从句的语序：???

That he broke the cup made his mother very angry. The problem is where we should stay.

The story is that a girl was abused by his step father.

主语从句：

概念：在主从复合句中，充当主语的从句，叫主语从句。 结构：连接词、语序

基本句型：根据引导词分类： 1. that/whether/if

That you are coming to London is the best news I have heard this long time. That she became an artist may have been due to her father’s influence. Whether it will do us harm remains to be seen. Whether they would support us was a problem. 总结：that 无意思；在从句中不做成分 Whether/if 有意思“是否”，在从句中不做成分 2. 连接代词引导主语从句， 在从句中充当主语，宾语，表语或定语：what, who, whose, whom, which“哪一个”, whatever, whoever, whichever, whomever(无论) What I have seen today has made a very deep impression on me. Whoever breaks this law deserves a fine.

Whichever of you comes in first will receive a prize.

What you need is more practice.

总结：引导词 有意思； 在从句中做成分：主语，宾语，表语或定语

3. 连接副词引导主语从句，并在从句中做状语，表时间，地点，方式和原因等。 When, where, why, how

When we will have a meeting is an important question. Where we shall do the test is still under discussion. 总结：引导词 有意思， 在从句中充当状语

考点：

一、it 做形式主语，代替that/whether引导的主语从句 Whether he will come back is unknown. It is unknown whether he will come back. That he will come back is true. It is true that he will come back.

It be+名词词组+主语从句（a pity, a shame, a fact, an honor） It is a pity that you can’t attend my birthday party. It be +形容词+主语从句

It is important/natural/impossible/necessary that we (should) keep the balance of nature. It be +过去分词+主语从句

It remains to be seen whether our team will win the game. It occurs to me that I should finish the homework first. It hits me that I should finish the homework first. It surprised him that they came to visit him suddenly. 二、whether与if区别： “是否” 1. 介词后用whether 2. whether 后加or not 3. whether后加to do

4. 在句首引导主语从句用whether 5. 表语从句、同位语从句用whether 三、主语从句的主谓一致（根据语意）

①主语从句做主语，谓语动词V一般用单数，(相当于非谓语动词做主语)当做一件事情来看

Whether he will come back is unknown. ②What 引导主语从句的特殊情况

What you left_____(be) only three books. What you said ____(be) of great importance. What he needs _____(be) friends.

③主语从句有and 并列（表同一件事情：V用单数；表两件事：V用复数） What he says and acts doesn’t concern me. What he says and acts don’t agree.

What I say and what I think ____(be) no business of yours.

3.连接副词：do you know when our teacher will come back? I really don’t what I should do next.
