二、名词性从句的连接词
一般规律：
? 针对从句 成分，如果作的是主语、宾语、表语的话，这个词就是连接代词；如果作的是各种状语，就叫连接副词；
如果不作任何成分，就叫从属连词。语序必须是陈述语序。如下表：
从属连词 that, if, whether

引导名词性从句
的连接词 连接代词 who, whom, what, whose, which, whichever, whatever, whoever



连接副词 when, where, how, why，as if, because
*重要表格：
类型 连接词 考点
主语从句 1.从属连词:that, whetherif 1.为了避免主语冗长,句子头重脚轻,经常用it作形式主语,
2.疑问代词:what, which, who, whom, whose 主语从句放在后面作真正的主语.连接代词what,
3.疑问副词:when, where, why, how whoever, whatever, whichever等引导的主语从句不宜用it
4.复合关系代词:whatever, whichever, 作形式主语。
whoever, whomever，whosever Whatever was said here has left us much to think.

2.从句作主语 ，谓语动词一般用单数
What引导的主语从句，可根据表语决定
What he needs that book.
What he needs __ some books.
1.从属连词:that, whether, if 1.引导宾语从句的that在下列情况下一般不省略：
2.疑问代词:what, which, who, whom, whose （1）宾语从句前有插入语。
3.疑问副词:when, where, why, how We hope, on the contrary, that he will stay at home with us.

（5）that从句单独回答问题时。

（6）在“it(形式宾语)+补语”之后时。

（7）位于句首时。如：

2.注意时态的呼应：主过——从过，主现——从实（客观
真理、格言谚语除外）
? I know he lived here ten years ago .
3.宾语从句的语序用陈述语序
4.否定的转移:若主语谓语动词为think, consider,
suppose, believe, expect,, imagine等, 其后的宾语从句若含
有否定意义,一般要把否定词转移到主句谓语上,从句谓
语用肯定式。

作为形式宾语而真正的宾语从句则放在句尾,
likelovehateappreciatehelplookdepend onsee to
count onrely on + it + whenifthat clause
I really appreciate it when our headmaster talks with the
guests in French.
介词+it+that宾从
We will depend on it that the weather is fine.
Sb.+ thinkfindmake + it +adj.n.+that clause
He makes it clear that he will agree with us.

6. 插入语疑问句：疑问词+简短疑问句（do you think,do
you believe,do you suppose,do you imagine…）+陈
述语序的句子？

A. that she would stay B. would she stay C. would
stay D. she would stay

not代替so

-______
A.I am not afraid so B. I don’t hope so C. I’m
afraid not. D.I believe it.

表语从句 一般结构是“主语+系动词+表语从句”。可1.在表语从句中，表“是否” 时，只能用 “whether”不
以接表语从句的系动词有be, look, remain, 能用“If”。
seem等。另外,常用的还有the reason why … 2. “that”不能省。
is that … 和It is because …等结构。 is was because+原因
从属连词：that whether as if as though It is was why+结果
连接代词：who whom whose which 4. The reason (why…for…)is was that….
what reason is that…
连接副词：when where why how
because
同位语从句 1.通常为：抽象名词+连接词（多为that）+同位语从句和定语从句的区别：
从句 1 同位语从句——that 只起连接作用，不作任何成分
2.部分可为：连接副词when wherewhy 定语从句 —— that 是关系代词，起连接作用和充
how whether 当宾语和主语
3.在have no idea 之后常用wh-引导同位语2同位语从句——同位语从句和前面的名词是同位关系，
从句. 对名词进行补充说明
I have no idea what he did. 定语从句 ——定从和前面的名词是所属关系，对名
词进行修饰，加以限定
3同位语从句——that 不能省
定语从句 ——that 在从句中作宾语时，可以省
判断下列句子是定从还是同位语从句
expressed the hope that they would come to visit
China again.
2. The hope that she expressed is that they would come to
visit China again.
fact that she works hard is well known
to us all.
4. I can't stand the terrible noise that she is crying loudly.
三、特别注意若干点
her的区别：if五不准
前置主语从句、表语从句、同位语从句和跟在介词后面的宾语从句中，在whether… or not 和whether to do 中whether
不能换成if
1） I asked her __________ she had a bike.
2）I don’t know ___________ he is well or not.
3）___________ we will hold a party in the open air tomorrow depends on the weather.
4）It hasn't been decided____________ we shall attend the meeting.
5）We’re worried about ________ he is safe.

6）The question is _________ he should do it.
7）The doctor can hardly answer the question__________ the old man will recover soon.
8） I don’t know _______ to go or to stay at home.
2. that和whether的区别:that无意义，whether有疑问意义
I don’t know ________ he can join us or not.
I’m sure_______ he can join us.
It is none of your business _________ I love her.
It is none of your business _________I don’t love her.
I doubt____________ he can speak English. I don’t doubt ____________ he can speak English.
，what的区分
what不但起连接作用，而且有具体意义，意为“所……的”（the thing(s) that），在从句中作主语，表语或宾语。而that 在
从句中无词义，只起连 接作用。简言之，从句中如果不缺少成分时，连接词用that，否则用what。
1）_______ he needs is more practice.
2）_______ he got the first place in the competition surprised us.
3）The truth is ______ I didn’t go there
4）He is not _______ he used to be 20 years.
5）_______impressed me most was ______such a little boy could play the violin so well.
4.表示坚持、命令、建议、要求的名词从句的语气要用虚拟语气,结构为 should + do, should 可省略
It was ordered that all the soldiers____to the front.
send be sent be sent go
r = anyone who + 定语从句
whomever=anyone whom +定语从句
Whatwhatever , when whenever , where wherever 的含义基相
同，只是后者比前者语气更重。在意义上也有细微差别：
whatever 含义为 anything that
whenever 含义为 any time when
wherever 含义为 any place where
改错：
1)Who leaves the room last ought to turn off the lights .
2)Mary hopes to become a friend of whomever shares her interests .
6.名词从句中须使用陈述语序
7.主句谓语动词是过去时态，从句也必须使用过去相应的时态。(客观真理、格言谚语除外)
