宾语从句-名词性从句(基础)

动词后+从句

 

1.从句部分取决于从句是

一般疑问句、

We must find out who did all these.

特殊疑问句

I want to know whether he will come.

还是陈述句

I hope that he will come.

 

 

2.宾语从句的时态：如果宾语从句前的动词是过去式，则宾语从句的时态应相应变成过去时态；

如果宾语从句是客观事实或真理，不管宾语从句前的动词是什么时态，宾语从句都用一般现在时；

ToddPark, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake.

 

3.宾语从句后接陈述句，用that引导，则that一般可省略；

I think that you are right.

 

4.宾语从句如果谓语动词是doubt,后面接的一般疑问句通常用whether或if引导；如果前面的谓语动词是don'tdoubt,则后面从句的连接词一定是that；

I doubt whether he is telling the truth;

I don't doubt that he is telling the truth.

如果谓语动词是wonder,句型为I wonderif (固定句型),后面的连接词不能用whether;

 

 

5.否定转移

Think,believe,suppose,expect,fancy,imagine等动词后面宾语从句的否定转移到主句中，即主句的谓语动词用否定式，而从句的谓语动词用肯定式。

I don't think I know you.

I don't believe he will come.

将seem,appear等后的从句的否定转移到前面。

It doesn't seem that they know where to go.

It doesn't appear that we'll have a sunny day tomorrow.
