宾语从句

从句部分的连词取决于从句时一般疑问句、特殊疑问句还是陈述句;

eg:We must find out who did all these.

I want to know whether he will come.

I hope that he will come.

① 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时什么时态,宾语从句都用一般现在时; eg:The teacher told us that the earth is round. eg:Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake.

② 宾语从句后接陈述句,用that引导,则that一般可以省略; eg:I think that you are right.

③ 宾语从句如果谓语动词是doubt,后面接的一般疑问句通常用weather或if引导;如果前面的谓语动词是don't doubt,则后面从句的连接词一定是that; eg:I doubt whether he is telling the truth. I don't that he is telling the truth.

宾语从句如果谓语动词是wonder,句型为I wonder if,后面的连接词不能用weather;

④宾语从句的否定转移:

① think, believe, suppose, expect, fancy, imagine等动词后面宾语从句的否定词转移到主句中,即主句的谓语动词用否定式,而从句的谓语动词用肯定式; eg:I don't think I know you.

I don' t believe he will come.

② 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.
