宾语从句(The Object Clause)专练
借这个机会和大家温习一下宾语从句
●宾语从句在复合句中作主句的宾语。宾语从句通常由下面一些词引导。
1.由that引导(that在口语或非正式文体中常省略)。
2.由what, when, where, which, who, how, why等连接代词或连接副词引导。
3.由连词whether或if引导(口语中常用if)。
●应注意的几个问题:
1.宾语从句可放在形容词后。常用形式是“be+形容词+宾语从句”
①I am glad you like it.
②I'm sorry that you didn't pass the exam.
2.宾语从句与主句时态的一致。
(1)主句是现在(或将来时态时),宾语从句可根据实际需要用不同的时态。
①He says Mary is playing with the cat.
②He says Mary often plays with the cat.
③He says Mary will play with the cat.
④I think he left yesterday morning.
(2)主句时态是一般过去时,从句要用过去时态的某种形式。
①He said Mary was playing with the cat.
②He said he hoped to be back soon.
(3)当从句所表示的是客观事实或客观真理时,该从句都用一般现在时,不用过去时。★★★
①He said light travels much faster than sound.
3.宾语从句中的否定前移。如果主句谓语动词是think, believe, suppose等,而从句的意思是否定的,这时主句的谓语动词用否定式,从句用肯定式。
①I don't think you are right.我认为你不对。
②I don't believe he will give up.我相信他不会放弃的。
4.将特殊疑问句变成宾语从句时,从句的语序要用陈述语序,标点符号由主句决定。
When will the meeting begin? ⇒I want to know when the meeting will begin.
5.将一般疑问句变成宾语从句时,则用if/whether(是否)连接,同时变成陈述句语序。
Are you an English teacher? ⇒ He asked if I was an English teacher.
在下列情况下只能用whether
①介词后的宾语从句 I am thinking about whether we should go fishing.
②宾语从句提前时 Whether this is true or not, I can’t say.
③直接与or not连用时 I don’t know whether or not he was ready.
④在带to的动词不定式前 She hasn’t decide whether to go or not.
★if也可引导条件状语从句,表示“如果”(主将从现,主过从过)。
比较:
I don’t know if he will come.
If he comes, I will tell you.
6.在变宾语从句时,要注意以下几点。
(1)连接词(2)人称(3)语序(4)时态(5)标点 |
