三种常用的从句宾语从句在句中起宾语作用的从句。
1.注意正确使用引导词
(1)当宾语从句由陈述句变化而来时,用that来引导从句,其中的that无具体意义,一般可以省略。
He tells me (that) he is going shopping this Sunday.
他告诉我说本周日他要去购物。
She said (that) the bank was near the hotel.
她说银行就在宾馆附近。
(2)当宾语从句由一般疑问句变化而来时,可用if或whether来引导从句,意为“是否”。
She asked me if (whether) she could join us.
她问我她是否可以加入我们的队伍。
He wondered if (whether) the workers had finished the work.
他想知道,工人们是否已经完成了工作。
(3)当宾语从句由特殊疑问句变化而来时,特殊疑问词就是宾语从句的引导词,如who, whose, what, which, when, where, why, how 等。
Do you know who broke the door?
你知道谁弄坏了门吗?
She asked me whose pen that was.
她问我那是谁的钢笔。

C.who D.where
2.注意正确使用语序
(1)在含有宾语从句的复合句中,宾语从句都要使用陈述语序,即“引导词+主语+谓语+其他”。
When did the train leave? I want to know.
→I want to know when the train left.
Does the shop close at six every day? Do you know?
→Do you know if/whether the shop closes at six every day?(2)如果是由do, does, did构成的疑问句,在转换为宾语从句时,要去掉do, does, did,且从句中的谓语动词要根据主句时态作出相应的变化。
Do they often play basketball?He asked.
→He asked if they often played basketball.
What time did she get up? The young man asked.
→The young man asked what time she got up. (3)如果是will, be, have, can组成的疑问句,在变为宾语从句时,需把will, be, have, can返回到句中原来的谓语位置上,并根据主句时态作相应的变化。
Will you be free tomorrow?She asked me.
→She asked me if (whether) I would be free the next day.
Has she seen the movie yet? I want to know.
→I want to know if (whether) she has seen the movie yet. 3.注意正确使用时态
(1)如果主句是一般现在时、一般将来时或祈使句时,宾语从句的时态不受限制,可以根据实际表达的需要来确定。
Could you tell me what he said at the meeting?
你能告诉我他在会上说了什么吗?(一般过去时)
He will tell us that he has been able to look after himself.
他将告诉我们他已经能够照顾自己了。(现在完成时)
Tell him when we will start.
告诉他我们将什么时候动身。(一般将来时) (2)如果主句是一般过去时,宾语从句应与主句保持一致,即使用过去时态的某种形式。
He said that he was born in Wuhan in 1985.
他说他于1985年出生在武汉。
They said that they had already finished the work.
他们说他们已经完成了工作。(3)如果宾语从句所叙述的是客观事实、格言、科学真理等时,从句时态不受主句限制,用一般现在时。
Everyone knew there are sixty minutes in an hour.
大家都知道一小时是60分钟。(客观事实)
She said that two heads are better than one.
她说三个臭皮匠赛过一个诸葛亮。(格言)
He said that light travels faster than sound.
他说光比声音传播得快。(科学真理)4.否定前移
在宾语从句中,当主句的谓语动词为think(认为), believe(相信), expect(期望), imagine(想象), suppose(猜测)等时,如果主句主语为I(we)时,从句中表示否定意义的not应移到think, believe, expect, imagine, suppose前。
I don't think he is right. 我认为他不对。
I don't suppose he will come. 我猜测他不会来。
注意:如果主句主语不是I(we),则not不前移。
