(二)宾语从句三要素:________ 、______________、_______
1、语序:陈述句语序 即:主句+连接词+从句(主+谓+其他成分)
注意:当从句的原句为以下句子以及what,who作主语时,语序不变。
1.What’s wrong? 2.What’s the matter with you? 3.What happened?
4.What’s up? 5.What’s happening?
6.I don’t know what’s the matter. 7. Can you tell me who is over there?
8.We wonder ___________________________________(我们想知道Mike怎么了。)9.The teacher wants to know_______________________(老师想知道谁回答问题)以上句子,what,who在从句中都是作主语,句子本身就是陈述句语序,所以不需要改变语序。
2、引导词(连接词)引导宾语从句的引导词分为三类即:表示陈述语气用that,表示一般疑问语气,含有“是否,能否”的意思用whether和if引导,表示特殊疑问语气由特殊疑问词引导,
(1)从属连词that引导:作从句的原句是陈述句。(即陈述句的宾语从句)(在口语中that常省略)eg: I hear that English is not easy.
(2)从属连词 whether,if“是否” 引导:用它引导从句,说明对陈述的事物不明确或不清楚,有疑问语气,常用在ask,wonder,can(could)you tell me等后。原句为一般疑问句、选择疑问句或反义疑问句。
eg:Could you tell me if(whether)Miss Brown lives in that house?
注意:1.只能用whether不能用if的情况:
在介词后面:
I’m thinking of whether we should go fishing.
We didn’t think about whether it would rain the next day.
(2)在动词不定式前:
They asked me whether to sit at the front.
当与or not 连用时,或提出两种选择时:
I don’t know whether he’s free or not.
Mary asked whether I was doing my homework or not.
Tell me whether you’d like to go shopping or tidy the room.
在动词discuss后的宾语从句中:
We discussed whether we would have sports meeting next week.
宾语从句提前时:Whether this is true or not,I can’t say.
2.只能用if 不能用whether的情况:
(1)引导否定概念的宾语从句时:
She asked me if I hadn’t finished my homework.
引导条件状语从句,if意为“如果”时:
