宾语从句三要素

1.关联词

2.语序

3.时态

〈一〉宾语从句的引导词1)当从句是陈述句时用that来引导,在口语或非正式文体中可省略。

I hear( that) he will be back in a month,

2)当从句是一般疑问句时，用 if或whether(是否)来引导宾语从句。

△I asked whether/ if they had been to U.S.A.

△No one knows weather/ if my sister likes the present.

3）当句末有or not时，只能用whether.

Will he come?

I don't know if/whether he will come.

I was not sure whether he would come or not,

4)当宾语从句是特殊疑问句时用who, whose, whom,which,what, when, where, how, why等词引导。

△I don't know 〈who 〉can help me.

△Do you know 〈who 〉has won the game?

△Can you tell me 〈where〉 I can buy some stamps?

△I don't know〈 why 〉he hasn't come yet.

I don't know. Could he pass the exam?

I don't know whether he could pass the exam or not.我不知道他是否能通过考试。

〈三〉宾语从句的时态1)当主句是一般现在时,宾语从句可以根据实际需要用各种时态。

△Lili says she will leave a note on the

teacher's desk丽丽说她会留个便条老师的桌子上。

2)如果主句的谓语动词是一般过去时,宾语从句必须用过去时的某种形式。

①从句的动作和主句的动作紧接着发生，从句用一般过去时。

The policewoman asked the little boy where he lived?

女警察问小男孩他住在哪里吗?

②当从句的动作和主句的动作同时发生，则从句用过去进行时。

The woman told me that she was looking

for her son.

③如果宾语从句的动作发生在主句动作前，则从句用过去完成时。

My father once told me that he had been to America twice.

④如果宾语从句的动作发生在主句动作后,则宾语从句用过去将来时。

My son told me yesterday that he would become an engineer in the future. 我儿子昨天告诉我他将来会成为一名工程师。

⑤如果宾语从句表示的是客观真理,其谓语动词则用一般现在时。

△The geography teacher told us that the earth goes around the sun.地理老师告诉我们地球绕着太阳转。

△The physics teacher told us that the

speed of light is much faster than that

of sound

〈四〉宾语从句的简化

=I hope to visit Australia.
