主语从句讲解及练习

主语从句

一、概述：

在句子中起名词作用的各种从句统称为名词性从句。

根据它们在句中的语法作用，这类从句又可分为主语从句、同位语从句、表语从句和宾语从句。

二.主语从句主要有三类：

（1）由连词that引导的主语从句:

引导词that无含义,在句中不做成分,不可以省。

例如：

Thatyouwillwinthemedalseemsunlikely.

你想获得奖牌看起来是不可能的。

Thatyouaresoindifferentbothersme.

你如此冷淡使我很烦恼。

Thatshesurvivedtheaccidentisamiracle.

她在事故中幸免于难简直是奇迹。

（2）用连词whether引导的主语从句:

whether有含义（是否）,在句中不做成分,不可以省。

例如：

Whethersheiscomingornotdoesn’tmattertoomuch.

她来不来都无关紧要。

（3）用连接代词引导的主语从句（在由连接代词who,whose,whom,which,what,whoever,whomever,whichever,whatever引导的名词性从句中，其连接代词在句中起名词性作用，担当一定成分）.

例如：

Whatyouneedismorepractice.

你所需要的是更多的训练。

WhatIwanttoknowisthis.我想知道的就是这事。

Whateverwedoistoservethepeople.

我们无论做什么都是为人民服务。

（4）连接副词when,where,why,how引导的名词性从句（其连接副词有含义,在句中作状语。

）

eg:

Whereweshouldleaveitisaproblem.

Whentheywillcomehasn’tbeenmadepubic.

他们什么时候来还不知道。

三.注意点:

1.it做形式主语,而将主语从句放在句末（尤其是当谓语较短时）。

例如：

Thatlighttravelsinstraightlinesisknowntoall.

光沿直线传播，这是众所周知的事。

=Itisknowntoallthatlighttravelsinstraightlines.

众所周知光沿直线传播。

Whentheplaneistotakeoffhasnotbeenannounced.

飞机何时起飞还没有宣布。

=Ithasnotbeenannouncedwhentheplaneistotakeoff.

还没有宣布飞机何时起飞。

（当what引导的主语从句表示“…的东西”时，一般不用it作形式主语。

）

错:

Itisabookwhathewants.

对:

Whathewantsisabook.他想要的是本书。

例如：

Hasitbeensettledwhowillbesenttocarryoutthetask?

谁将被派去执行这项任务决定了吗？
