that与who的用法区别

回复：what，that，where ，who ，how在不同从句中的用法

四组名词性从句引导词用法区别

1. what 与that的用法区别

两者均可引导主语、表语、宾语从句，区别是what可在从句中用作主语、宾语或表语，意为“什么”或“所…的”，而that仅起连接作用，本身没有实际意义，在从句中也不充当任何句子成分(引导宾语从句时通常可以省略)：

He doesn’t know what she likes. 他不知道她喜欢什么。

What you say is quite right. 你所说的相当正确。

I believe (that) he will come to see us. 我相信他会来看我们的。

It’s a pity (that) he didn’t finish college. 真遗憾他大学没毕业。

另外，that 可引导同位语从句，但 what 通常不用于引导同位语从句：

I had no idea that you were here. 我不知道你在这儿。

2. whether与 if的用法区别

两者的用法异同注意以下几点：

(1) 两者均可引导宾语从句，表示“是否”，常可互换：

He asked if [whether] we wanted a drink. 他问我们是否想喝一杯。

He didn’t tell me if [whether] he would come. 他没有告诉我他是否会来。

【注】若是引导条件状语从句，则只能用 if(意为“如果”)。

(2) 当引导一个否定的宾语从句时，通常用 if 而不用 whether：

I don’t care if it doesn’t rain. 我不在乎天是否下雨。

【注】在个别词语(如 wonder, not sure 等)后的从句否定式有时也可用 whether 引导：

I wonder if [whether] he isn’t mistaken. 我想知道他是否错了。

用来说明主句中某一名词或代词(有时也可说明整个主句或主句中一部分)而起定语作用的句子叫作定语从句。

一.词引导的定语从句

1. 关系代词用来指代先行词是人或物的名词或代词

句子成分 用于限制从句或非限制性从句 只用于限制性从句

代替人 代替物 代替人或物

主语 Who which that

主语 Whom which that

宾语 Whose(=of whom) whose(=of which)

例1：This is the detective who came from London.

例2：The book which I am reading is written by Tomas Hardy.

例3：The desk whose leg is broken is very old.

例4：This is the room that Shakespeare was born in.

2.关系代词的用法

(1) 如果先行词是all, much, anything, something, nothing, everything,

little, none等不定代词，关系代词一般只用that，不用which。例如：

All the people that are present burst into tears. (2) 如果先等词被形容词最高级以及first, last, any, only, few, mush,

no, some, very等词修饰，关系代词常用that,不用which, who，或whom。例如：

关系代词that和which 都可以指物，that 和Who 都可以指人，其用法区别： 1）不用that的情况 a) 在引导非限定性定语从句时 (错) The tree, that is four

hundred years old, is very famous here. b) 介词后不能用 We depend on the

land from which we get our food. c)多用who 的情况 ①关系代词在从句中做主语 A friend who helps you in time of need is a real friend . ②先行词为those ,

people 时 Those who were either fools or unfit for their offices could not see the

cloth . ③先行词为all, anyone , ones , one 指人时 One who doesn’t work hard

will never succeed in his work . ④在There be句型中 There is a stranger who

wants to see you . ⑤在被分隔的定语从句中 A new teacher will come

tomorrow who will teach you German . ⑥在有两个定语从句的句子中，其一用who,其二用that,但若先行词后接两个以上的并列定语从句时，后一个必须重复前一个关系代词。 The student who was praised at the meeting is the monitor that is

very modest and studies very hard . There is a teacher who is always ready to help
