重难点

1. 主语从句

在句中起主语作用的从句称为主语从句。引导主语从句的连接词主要有that，whether，who，what，which， when，where，how，why等。

(1)连接词引导的主语从句

3．宾语从句中的时态

(1)主句的谓语动词是一般现在时，应根据实际情况而定。

She says that she works from Monday to Friday．

她说她从周一至周五上班。(从句是一般现在时)

She says that she has never been to Mount Emei．

她说她从未去过峨眉山。

(2)主句的谓语动词是一般过去时，其宾语从句的时态一般要用适当的过去时态。

whatever,

他说昨天下午没有课。

He said that they were having a meeting at that time．

他说他们那时正在开会。

(3)当宾语从句是表达客观真理和规律的句子时，其时态仍旧用一般现在时。

4．表语从句

问题是在这么大的一个城市里我们能求助于谁。

That is what he wanted to say．这就是他想说的。

我的建议是约翰一个人到那里去。

5．同位语从句

同位语从句的先行词多为fact，news，idea，promise， thought，reply，report，information，possibility，feeling， word，story, doubt，remark等抽象名词。引导同位语从句的连词多为that。

The news that our team won the football game inspired all the fans．我们队赢了足球赛的消息对所有的球迷是极大的鼓舞。

6．名词性从句中的虚拟

(1)在It is necessary／natural／important／+ that从句中，从句中的谓语动词用“should+动词原形”表虚拟，且should可以省略。

It is necessary that the problem(should)be settled at once．这个问题必须马上解决。

(2)表示“建议、命令、要求”等意义的动词后接that句中时，从句的谓语动词要用虚拟语气，即“should+动词原形”。

他命令立即开始那项工作。

His mother insisted that he(should)not go to bed so late．他妈妈坚持他不要睡得太晚。

(3)如果主语是表示“建议、命令、要求、想法”等意义的名词时that引导的表语从句中也要用虚拟语气。

我们的决定是我们坐火车去那。

他说光比声音传播得快。

易 混 点

1．定语从句与同位语从句的区别

(1)从与引导词的关系看

定语从句是从句对其先行词的修饰或限制；而同位语从句是从句对前面抽象名词进一步的说明和解释。

The news that our team has won the game was true．

我们队赢了那场比赛的消息是真的。(同位语从句。补充说明news到底是一个什么消息)

The news that he told me yesterday was true．

昨天他告诉我的那个消息是真的。(定语从句。 news在从句中作told的宾语)

I made a promise that if anyone set me free I would make him very rich．

我许诺如果谁让我自由，我就让他非常富有。(同位语从句。补充说明promise到底是一个什么诺言)

The mother made a promise pleased all her children．

妈妈许下了一个令孩子们高兴的诺言。(定语从句。promise在从句中作pleased的主语)

(2)从所作成分看

that引导定语从句时为关系代词，需在定语从句中充当主语、宾语或表语等成分。that在定语从句中作宾语时，可省略。而that引导同位语从句时不作句子成分也不能省略。

The letter that I received yesterday was from my sister．我昨天收到的信是我妹妹写的。(that引导定语从句，在从句中作宾语)

They expressed the hope that we would go and visit Shanghai again．

他们表示希望我们再去访问上海。(that引导同位语从句，只起连接作用不作成分)

2．连接代词who与whoever的区别

whoever引导名词性从句时，相当于anyone who或those who，它既是从句的主语，又是主句的主语。而 who只作从句的主语，它引导的从句才是主句的主语。

Whoever has helped to save the drowning girl is worth praising．帮助救落水女孩的人值得表扬。

Who will be elected the president doesn't make difference to me．谁当选总统对我来说并不重要。

3．whoever与no matter who；whatever与no matter what区别

whoever和whatever既可以引导名词性从句，也可以引导让步状语从句；no matter who和no matter what只能引导让步状语从句。

Whatever(=No matter what)you may do．I will go there as planed．不管你怎么做，我都会按原计划去那。

Take whatever you want and leave me alone．

把你想要的拿走，不要烦我。
