A,由that 引导的陈述句性的宾语从句,在很多动词如say, think, wish , hope, see, believe, agree, expect, hear , feel等动词后。连词that只起连接作用,在从句中不做句子的成分,也无词汇意义,在口语中常被省略,但在大多数情况下还是以不省为好,特别是在笔语中。 例:I told him that he was right.

l在think,believe, suppose等动词引起的宾语从句中,有时谓语尽管是否定意义,却不用否定形式,而将think 等动词变为否定形式。

例:I don’t think you are right. (我认为你做的不对)


例:We think it wrong that he told a lie to everyone (我认为他向每一个人撒谎是错误的) B,由连词if、 whether 引导的表示“是否…”的宾语从句。Whether,if 在从句中不做句子的成分,一般情况下,whether和if 可以替换。

例:I don’t know if/whether he will come tomorrow.

The teacher asked if/whether we had finished the experiment.


例:Everything depends on whether we have enough money。

l宾语从句中有or not时不用if引导.

例:I don’t know whether the movie star will come or not.


例:Whether to go there or not hasn’t been decided.

C,由wh-引导的宾语从句。连接代词who,whom,whose, what, which,和连接副词when, where, why, how 等连接的宾语从句,它们在句中即有连接从句的作用,又在句中充当句子的成分。

例:Do you know which film they are talking about? (which做定语)

I don’t know where he lives. (where 做地点状语)



例:I believe that they will come soon.

He asked me whether I was a teacher.

They wanted to know what they can do for us.





例1)She says that she is a student.

2)She says that she will fly to Japan in a week.

3)She says that she has finished her homework already.

She said that she had finished her homework already.

如果宾语从句说的是客观真理、自然现象或事实时,这时宾语从句要用一般现在时态。 例:The teacher said that the earth goes round the sun.

He told me that Japan is an island country.

Could you tell me…是用来征询对方的意见,语气委婉,并不表示过去。

例:Could you tell me when we will visit the Histury Museum?

She said that she had been to England before.
