一、 当由陈述句充当宾语从句时,用that引导,that 无词义,在口语或非正式文体中常省略。如:
She said that she would leave the message on the headmaster's desk. 她说她会把留言条放在校长桌子上。
He said that he could finish his work before supper.他说他会在晚饭前完成工作。
二、 当由一般疑问句充当宾语从句时,用if 或whether 引导,意为“是否”。如:
Alice wanted to know if/whether her grandmother liked the bag. 爱丽斯想知道她祖母是否喜欢这个包。
I don't know whether he'll come the day after tomorrow. 我不知道他后天是否会来。
但在下列情况下只能用whether:
1. 在具有选择意义,又有or 或or not 时,尤其是直接与or not 连用时,往往用whether(if …or not 也可以使用)。如:
Let me know whether / if he will come or not.(= Let me know whether or not he will come ) 让我知道他是否能来。
I don't know whether / if he does any washing or not.(= I don't know whether or not he does any washing. ) 我不知道他在家洗不洗衣服。
I wonder whether we stay or whether we go. 我想知道我们是去还是留。
2. 在介词之后用whether 。如:
I'm interested in whether he likes English. 我关心的是他是否喜欢英语。
We're thinking about whether we can finish the work on time. 我们正在考虑是否能按时完成这项工作。
I was worried about whether I hurt her feelings. 我担心是否伤害了她的感情。
3. 在不定式前用whether。如:
He hasn't decided whether to visit the old man. 他尚未决定是否拜访那位老人。
I don't know whether to go. 我不知去否。
He hasn't decided whether to go by bus or by train. 他还未决定是乘公共汽车去还是坐火车去。
4. whether 置于句首时,不能换用if。如:
Whether this is true or not , I can't say. 这是否是真的我说不上来。
5. 引导主语从句和表语从句时宜用whether。如:
Whether she will come or not is still a question. 她是否能来还是个问题。
The question is whether we can catch the bus. 问题是我们能否赶上公共汽车。
6. 若用if 会产生歧义时,要用whether。如:
Please let me know if you like the book.
可理解为:
① Please let me know whether you like the book. 请告诉我你是否喜欢这本书。
② If you like the book, please let me know. 你如果喜欢这本书,请告诉我。
三、 如果宾语从句原来是特殊疑问句,只需用原来的疑问词引导。如:
Could you tell me where we will have the meeting this afternoon? 你能告诉我我们今天下午将在哪儿开会吗?
I don't know who bought the present for me. Is it Jack? 我不知道谁给我买了礼物。是杰克吗?

在各类考试中,同学们常会遇到把含有宾语从句的复合句转化为简单句,使其与原句意思相同(或相近)的试题。下面就介绍几种常用的简化宾语从句的方法:
方法一:当主句谓语动词是hope, decide, wish, choose, agree, promise等,且宾语从句的主语与主句主语一致时,宾语从句可简化为不定式结构。例如:
Li Ming hopes he will be back very soon. →Li Ming hopes to be back very soon.
We decided that we would help him. →We decided to help him.
方法二:当主句谓语动词是know, learn, remember, forget, tell等动词,且主句主语与从句主语一致时,宾语从句可简化为“疑问词+不定式”结构。例如:
She has forgotten how she can open the window. →She has forgotten how to open the window.
注:当主句谓语动词是tell, ask, show, teach等动词,且后带双宾语,从句主语和间接宾语一致时,宾语从句可简化为“疑问词+不定式”结构。例如:
Could you tell me how I can get to the station? →Could you tell me how to get to the station?
方法三:当主句的谓语动词是order(命令),require(需要)等时,如果主句和从句的主语不一致,宾语从句可简化为“名词(代词)+不定式”结构。例如:
The headmaster ordered that we should start at once. → The headmaster ordered us to start at once.
方法四:某些动词后的宾语从句,可以用介词加动名词(短语)等其他形式简化。例如:
He insisted that he should go with us. →He insisted on going with us.
The poor boy doesn’t know when and where he was born. →The poor boy doesn’t know the time and the place of his birth.
方法五:某些动词后面的宾语从句可转化为“宾语+V-ing形式(作宾语补足语)”结构。例如:
Liu Ping found that there was a wallet lying on the ground. → Liu Ping found a wallet lying on the ground.
方法六:动词seem后的宾语从句,也可以用不定式(短语)来简化,但句型需要进行适当的变化。例如:
It seemed that the boys were going to win. →The boys seemed to win.
除上述方法外,还有一些特殊句式的转化。例如:
I found that it was difficult to learn English well. →I found it difficult to learn English well.
Soon we found that the ground was covered with thick snow. →Soon we found the ground covered with thick snow.
They found that the box was very heavy. →They found the box very heavy.
