高二英语选修8 Unit 1 第四课时Grammar
名词性从句：主语从句，宾语从句，表语从句，同位语从句
名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。因此，名词性从句分为主语从句、表语从句、宾语从句和同位语从句。
⏹1. What it was to become was a mystery.
⏹2. I don’t know who will help Henry to win the bet.
⏹3. His trouble is that he doesn’t know anybody in London.
⏹4. The fact that ships can go there surprises many people.
连接词:that,whether,if,as if ,as though
连接代词：what, who, whom, which, whose,
whatever, whoever, whomever, whichever
连接副词：when,where,how,why
1、宾语从句
宾语从句在复合句中起宾语作用，可以作动词的宾语，也可以作介词的宾语。引导宾语从句词有连词that，if，whether；连接代词who，whose，what，which；连接副词when，where，how，why等。e.g. (1) I think (that) women can reach very high achievements in many fields of science.
2) I wonder whether/if she remembered how many babies she had delivered.
3) Do you know who/whom Jack was speaking to?
注意点：1).宾语从句一律用陈述句的语序.
What is the matter 和what is wrong 除外
2).whether和if都可以引导宾语从句
但: (1).当whether后紧跟or not时,不用if.
例: I don’t know whether I will stay or not.
(2).介词后面的宾语从句不能用if.
例: I worry about whether I hurt her feeling.
3).that在宾语从句中的省略与保留
引导宾语从句的连词that也无实际意义,多数情况下可以省略.
由连词and连接的两个由that引导的宾语从句中,第一个that 可以省略,第二that不能省.
He told me (that) he would come and that he would come on time.
2、表语从句
表语从句在复合句中起表语作用.引导宾语从句词有连词as if,as though,that，what, which, who, whom, whose等.除在句子中起连接作用外，还可在从句中从当主语、表语、定语，且各有各的词义。
e.g. Tom is no longer what he used to be.
The question is which of us should come first.
The problem is who is really fit for the hard job.
The important thing is whose name should be put on the top of the list.
注意点：1). 表语从句一律用陈述句的语序
2).表语从句的引导词that无实际意义,但不能省略.
3).表语从句只能用whether,而不能用if 引导.
What many people are worried about is whether we will be able to build a better future.
4）The reason why he was late this morning is because that there was a lot of traffic on the road.（改错）
The reason why + 句子be that + 从句.
Eg. The reason why he was late this morning is that there was a lot of traffic on the road.
或This / it /that/ is because + 从句…等句型.
Eg. He was late this morning. That was because there was a lot of traffic on the road.
3、主语从句
做主语用的名词性从句，因其在复合句中做主语，又称主语从句，引导主语从句的有连词that ，whether，连接代词who ，what ，which，连接副词when，where，how，why等。
e.g. That she left him cut him to the heart.
What seems easy to some people seems difficult to others.
Whether it will please them is not easy to say.
注意：1).主语从句一律用陈述句语序,即主语在前,谓语在后.
Eg.下面哪一个是正确的？
When will he come is not known.
When he will come is not known.
