英语中的宾语从句是怎么表达的呢，要怎么去写这宾语从句

宾语从句在复合句中作主句的宾语。整个复合句的结构以主句开始，动词是及物动词，且宾语从句要用陈述语气。

That 引导的宾语从句。在口语或非正式文体中that 可以省略。有些表示人的感情的形容词，如：happy,glad,pleased,surprised,excited,sure,sorry,afraid等后也可接that 引导的宾语从句.

Eg.1.I hope that I can pass the exam.

2.He thought that he could work out the problem.

3.We are afraid that we can´t swim across the river.

4.They are sure that they can win the match.

由连接代词和连接副词引导的宾语从句。他们在从句中担任一定的句子成分，具有一定意义，不能省略。

Eg.1.I don´t know who will come this afternoon?

2.Could you tell me whom you are waiting for?

3.I want to know where he works?

4.I don´t know what is wrong with you?

注意：1.当what,who, whom,which等疑问代词作宾语从句里句末介词的宾语，又来引导宾语从句时，句末的介词不可省掉。Eg.I don´t know which room they live in.

2.疑问词引导宾语从句同疑问词与不定式转换。

1．）当从句主语和主句主语是同一个人或物时。

Eg.They can´t decide when they should leave the school.

= They can´t decide when to leave the school.

2.)当从句主语和主句的间接宾语一致时。

Eg.Please tell me what I should do first.

= Please tell me what to do first.

由if,whether引导的宾语从句。

Eg.1.I want to know if/whether I’m right.

2.Can you tell me whether he is right or wrong(not).

只用whether情况.

具有选择意义又有or 或or not时，尤其是直接与or not 连用。

Eg.Iet me know whether,if he will come or not.

=Let me know whether or not he will come.

在介词后。Eg.We are thinking about whether we can finish the work on time.

在不定式前。Eg.I don´t know whether to go there.

宾语从句放在句首时。Eg.Whether this is true or not,I can´t say.

引导主语从句和表语从句时。Eg.1.Whether she will come or not is still a question

2.The question is whether we can catch the bus.

在discuss引导的宾语从句中。Eg.They discussed whether they would go there.

若用if会引起歧义时。Eg.Please let me know if you like the book.可理解为：

Please let me know whether you like the book.

If you like the book,please let me know.

2.只用if情况：

1．）在条件状语从句中。Eg.I’ll go to the park if it doesn’t rain tomorrow.(如果)

2．）引导的宾语从句为否定句时。Eg.I don´t know if he didn´t come yesterday.

宾语从句注意几点。

宾语从句要用陈述语气。

时态方面：

1．）主句：一般现在时。 从句：可以用任意时态。

2.）主句：一般过去时。 从句：过去的相应时态。

3.注：不管主句是什么时态，从句仍用一般现在时的情况：

当从句所叙述的是客观事实，真理，自然现象，名言警句，谚语等时。

Eg.1.Our teacher told us light travels faster than sound.

2.He said time is money.
