主语从句与宾语从句

主语从句与宾语从句

一、名词性从句是四位从句的总称：主语从句、宾语从句、同位语从句、表语从句。这些从句都起到类似于名词的作用。

主从：一个句子充当大句子的主语，就叫主语从句。例如；

What I need is money.(主语是What I need作大句的主语)

It was not obvious that water is fundamental to the development of life.（It是形式主语，真正的主语是that 从句。）

主语从句的位置有两种，一种是放于句首；一种是用It 作形式主语，从句被放后面。

二、宾语从句：一个小句子充当大句子的宾语。

He asked me how old I was .

She took it for granted that I’d be back home an hour ago.（It 作形式宾语，真正的宾语是后面的that从句。）

考点一：语序

What I want to do is to go home immediately.陈述语序。

I asked where the famous restaurant was .陈述语序。

名词性从句的语序应该是陈述句语序。

删除疑问语序（be /助动词、情态动词+主语）

考点二：引导词

That（没成分）

That the earth moves around the sun is known to all.(that 引导的句子作大句子的主语，that不能丢。)

Whether /if （有时互换，主语从句只能用wheather引导，不能用if .可用if 的地方都能用wheather。）

Whether the meeting will be put off depends on the weather .

疑问代词：what,who, whom,which,whose 在从句中有成分

What he has is just money.（在从句中有成分作宾语）

疑问副词：where ,when,why,,how在从句中有成分

Why he didn’t attend class is not know yet.

That：引导名词性从句时无成分，无词义，有时可以省略。

Whether /if引导名词性从句时无成分，是否。

特殊疑问代词：主，宾，表，定。

疑问副词：状。

考点三：no matter+疑问词（what）VS疑问词（what）+ever

Whatever he says must be put down .

No matter what he says/Whatever he says,I will not change my mind.

意思相同，但语法不一样。第一句主从，第二句让步状语从句。以ever开头的引导主从或者状语从句，而以no matter 开头的不能引导名词性从句，只能引导状语从句，所以选ever 就一定对。

考点四：建议、命令、要求类+宾从

The doctor suggested that an operation (should)be done immediately on the patient.

初中讲过当主句是一般过去时态的宾语从句：主过去，从句也过去。当主句的动词是建议、命令、要求类的动词时，后面的宾从必须是should+动词原形且should可以省略。此时不管。主语是谁，不管主句是什么时态都不能改变动词是原形的要求.once表示建议、命令、要求类的动词suggest,advise,propose,demand,require,insist,request,ask,command,order后面如果后

面接宾语从句,从句should+动词原形，其中should可以省略。

考点五：It作形式主语，从句作真主语。(要么考填连接词、要么考填假主语it)

It bothers me whether you love me or not .

It is said that you have fallen in love with him.
