  2020考研英语语法体系:名词性从句

  名词性从句

  在主从复合句中,从句可以充当主句的主语、表语、宾语或同位语。由于在多数情况下,主语、表语、宾语或同位语这四种句子成分由名词性词类充当,所以,我们把这些作用相当于名词的从句统称为名词性从句,把充当主语、表语、宾语或同位语的从句分别称为主语从句、表语从句、宾语从句或同位语从句。也就是说充当什么成分就叫什么从句。名词性从句由连接词(或关联词)引导。

  常用的连接词有:

  疑问词(who, whom, whose, what, which, where, why, when, how)可以引导主语、宾语和表语从句。

  它们的特点是:

  1、疑问词有本身的词义

  2、疑问词在从句中担当句子成分,如主语、宾语或状语

  3、这种疑问词引导的从句一律用陈述语序,不能用疑问语序。

  For example:

  Do you know whom they are looking for? 你知道他们在找谁吗?(宾语从句,陈述语序。不能是whom are they looking for?)

  I don’t know who did it. 我不知道这是谁干的。(宾语从句。在从句中如果疑问词作主语,其陈述语序和疑问语序一致。)

  She asked me where I had been. 她问我到哪儿去了。(宾语从句。陈述语序,不能是where had I been. 直接引语,间接引语。注意这句话的时态。)

  Can you tell me when the train will arrive? 你能告诉我火车什么时候到吗?(宾语从句。陈述语序,不能是when will the train arrive. 直接引语,间接引语。)

  I don’t know why he hasn’t come yet. 我不知道他为什么还没来。(宾语从句,陈述语序。不能是why hasn’t he come yet.)

  He didn’t tell me what you were doing. 他没和我说你在干什么。(宾语从句,陈述语序。不能是what were you doing.)

  What you have done might do harm t other people. 你所做过的事情有可能伤害别人。(主语从句。what 作从句的宾语。陈述语序,不能是what have you done. 如果用疑问语序,意思发生了变化,成了“你做了什么?”。)

  I don’t know where he is now. 我不知道他现在在哪里。(宾语从句,陈述语序。不能是where is he now.)

  Where he went for his weekend is not known. 不知道他去哪里过的周末。(主语从句,where 作从句的地点状语。陈述语序,不能是where did he ...

高考英语总复习语法专项 名词从句

概述

一.定义: 在句中的作用相当于一个名词的从句叫做名词性从句

二.分类: 名词性从句包括四类, 分别是: 主语从句, 宾语从句, 表语从句, 同位语从句

三.引导词: 名词从句的引导词包括连词that / if / whether, 连接代词who / whom / whose / what / which, 连接副词when / where / how / why, 另外还有: whatever, whichever, whoever等

主语从句

一.定义: 在句中充当主语的从句就是主语从句

二.示例:

a. That he looked at me in that strange way puzzled me.

b. Whether we can control the floods is still uncertain.

c. What he wanted to see was an end to all the armies of the world.

d. When the broadcast station will be ready is unknown.

e. Who made the long distance call to him is not important.

f. Whether we’ll go depends on the weather.

三.应注意的问题:

a. It is certain that fuels like coal and oil cause a lot of pollution.

b. It was said that only three people in the world could understand it at that time.

2.whether引导主语从句时, 常置于句首 (此时whether不能用if代替), 也有后移的用法 (此时whether可以用if代替)

b. It is not yet known whether they will go there.

3.连接代词who, what, which和连接副词when, where, how, why引导主语从句时, 一般不后移
