宾语从句讲解
一、概念
宾语从句的宾语部分中有一个从句充当宾语。
二、可接宾语从句的动词
say 、tell 、think、 know、 see、 hear、 hope、 guess、 find、 feel 等,或由形容词构成的系表结构,如:afraid、 sure、 glad、 sorry等
三、宾语从句的标点符号。
宾语从句的标点符号取决于主句,如果主句是陈述句,句尾用句号;如果主句是疑问句,句尾用问号。
四、引导词。
1、that (从句是陈述句时,引导词用that  ,它本身无词义,不充当成分,在口语中可省略,但在正式场合不可省。)
2、if或whether (从句是一般疑问句时用if 或whether ,含义是“是否”。)
if、whether 一般情况下可以互换,但在构成whether…or not 句式只用whether
3、连接代词、连接副词(从句是特殊疑问句时用)
连接代词(what、 which、 who、 whose )
连接副词(when、 where、 how 、why )
五、宾语从句的同义句转换。
在宾语从句中经常会出现“疑问词+动词不定式”的结构,它可与“疑问词+主语+情态动词+动词原形”进行同义句转换。
Can you tell me how I can get to the station?
Can you tell me how to get to the station?

宾语从句的语序都用陈述句语序(即正常的主谓语序)
He says that Jim will miss a lot of lessons .
He asked whether we should hold a sports meeting .
Do you know what the population of Dalian is ?
七、宾语从句的时态。
1、主句是一般现在时,从句可根据需要选用任何时态。
He says that he is good at English
He says that he has been ill for two days
I don’t know if he e tomorrow
2、主句是一般过去时,从句可根据需要用相应的过去某种时态。(即一般过去时、过去将来时、过去完成时等)
He asked me where I lived
He said that she had been ill for two days
She said that she would return soon
3、当从句讲述的是客观事实或真理时,从句时态不受主句的影响,都用一般现在时。
The teacher said “light travels faster than sound”
He said that the earth is round
特例:Could you tell me …委婉的语气,常按照一般现在时处理。
Could you tell me where the nearest hospital is ?
