课中讲解

一. 判断名词性从句LV2

1. 名词性从句的定义

主从、表从、宾从在复合句中的功用和名词相同，分别作整个主句的主语、表语和宾语，

整个从句相当于一个名词，这样的从句就叫做名词性从句。

2. 名词性从句的分类

根据名词性从句在句中的不同作用可分为如下4类：

（1）主语从句

（2）表语从句

（3）宾语从句

（4）同位语从句Array

【小试牛刀】

辨析以下名词性从句的类型

1. That he will come is certain.

2. I know that he will come.

3. The truth is that I have been there.

4. The fact that she was late surprised us.

二. 名词性从句连接词的用法LV2

1. 主语从句

通常由从属连词that，whether，if和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。

（1）that在句中无词义，只起连接作用；

（2）连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。例

I wonder whether he will come or not.

（5）后接动词不定式时。

Can you tell me whether to go or to stay?

注意宾语从句中的时态呼应。例如：

He studies English every day.

He studied English last term.

I know (that) he will study English next year.

he has studied English since 1998.

当主句动词是过去时态（could, would除外），从句则要用相应的过去时态，如一般过去时，过去进行时，过去将来时等；当从句表示的是客观真理，科学原理，自然现象，则从句仍用现在时态。例如：

The teacher told us that Tom had left us for America．

think, believe, imagine, suppose等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。例如：

We don’t think you are here.

I don’t believe he will do so.

1. The companies are working together to create ________ they hope will be the best means of transport in the 21st century.

2. Could I speak to ________is in charge of International Sales please?

3. The old man was so angry and spoke so fast that none of his children understood_______ he said meant

The reason why he was late was that he missed the train by one minute this morning.

famous universities.

4. 同位语从句

同位语从句通常由that 引导，可用于同位语从句的名词有advice ，demand ，doubt ，fact ，hope ，idea ，information ，message ，news ，order ，problem ，promise ，question ，request ，suggestion ，truth ，wish ，word 等。例如：

The news that we won the game is exciting. I have no idea when he will come back home.

The thought came to him that Mary had probably fallen ill.

【小试牛刀】

1. We should consider the students’ request ________ the school library provide more books on popular science.

2. The reason I plan to go is ________ she will be disappointed if I don’t.

3. They were faced with the demand ________ this tax be abolished.

1．划分主从句LV3

找从句: 从句始于连接词，止于连接词后第二个谓语动词之前 2．判断句子完整性LV3

根据五大基本句型（主谓、主谓宾、主谓宾宾、主谓宾宾从、主系表）分析从句是否缺成分
