注意引导词与定语从句的引导词的区别
  • what 能引导名词性从句,并作宾语\主语

不能引导定语从句

  • that 在名词性从句中没有成份,只作标志

eg: I knew that I was wrong.

在定语从句中 作宾语\主语

eg: I get the very news that is important to me.

  • which 在名词性从句中加上名词做主语\宾语

eg: I don’t know which answer is right.

在定语从句中,单独做主语\宾语

eg: I see a film which was popular in the past.

pay attention
名词性从句的基本要求:Pay attention
  • 时态 :(与间接引语基本一致)

如果主句是现在时,从句时态可以不变,但如果主句是过去的时态,那么从句的时态一定要用相对应的过去的某种时态。当从句是客观真理,定义、公理、定理时用一般现在时。

宾:I know he lives here.

He asked whether his father would come back.

The teacher said that the earth travels around the sun.

表:That is what I was worried about two days ago.

It looked as if it was going to rain.

  • 语序:要用陈述语序

宾语从句

1 当宾语从句是一般疑问句时,由连词whether或if引导(口语中常用if), if/whether翻译成是否,

I wonder if (whether) the news is true or not.

但要注意在宾语从句中一些只用whether的情况:

A)在介词之后。(介词往往可以省略) 如:

It all depends on whether they will support us.

B) 后面直接跟动词不定式时。如:

He doesn’t know whether to stay or not.

C) 后面紧接or not 时。如:

We didn’t know whether or not she was ready.

slide8
其他从句只用whether的情况:

D)在表语从句和同位语从句中。如:

The question is whether the film is worth seeing.

The news whether our team has won the match is unknown.

B) 在主语从句中,只有用it 作形式主语时, whether和 if 都能引导主语从句, 否则, 也只能用whether如:

Whether we shall attend the meeting hasn’t been decided yet.

It hasn’t been decided whether (if) we shall attend the meeting.

slide9
5. He didn’t know ________ to do or not.

A. if B. whether C. what D. how

6._______the 2012 Olympic Games will be held in Japan is not know yet.

A. Whenever B. If

C. Whether D. That

slide10
2 在suggest, insist, demand, order,require等表示建议,命令,要求的动词后,从句的谓语动词要用虚拟语气,即: (should) +v.。如:

I insisted that he (should) do it at once.

She suggested that the work (should) be finished at once.

slide11
3 在接复合宾语的句子中, 为了保持句子平衡, 用it 作形式宾语,将从句放于句尾, 常接复合宾语的动词有: make, find, see, hear, feel, think...

I think it necessary that we take plenty of hot water every day.

--I think that we take plenty of hot water every day necessary

7. They make ____a rule whoever breaks the law will be punished. A. it B. that C. what D. this

slide12
表语从句

1. be, seem, look等动词后均可跟表语从句:

It seems that it is going to rain.

It looks as if it is going to rain.

2. as if, because 也可引导表语从句。

It was because I got up late.

注意:在表语从句中,当reason做主语时,引导词只能用that,不能用because,如:

The reason was that he didn’t catch the early bus. 原因是因为他没有赶上早班车。

slide13
4. 主句的主语是名词idea, advice, suggestion, order, request, requirement时, 表语从句应用虚拟语气,即: (should) +v.

主语从句

1. that 在主语从句中不充当任何成分,但不能省略

That they are badly in need of help is quite clear.

他们急需帮助,这是十分明显的。

2.主语从句在复合句中作主语, 它可以位于句首, 但常见的主语从句多放在句末,句首则用形式主语it

That the earth is round is true.

= It is true that the earth is round.

下面是一些常用it作形式主语的句型

slide17

(1) It is+名词+从句
