宾语从句的特殊疑问词有什么
说全点,再讲讲用法,
宾语从句的特殊疑问词有什么
哈哈,我今天刚讲了宾语从句哦.
关系词1:that(引导陈述句,没有意义,不作句子成分,做宾语时可省略)
例:I think that they will win the game.
关系词2:if/whether(引导一般疑问句,表是否,不作句子成分,不可省略)
例:I don't know whether (if) my mother will buy a computer.
whether和if一些时候可互换,只能用whether的情况:
1、后面有or,或者or not时,比如 He asked whether they would come on time or not.
2、后跟不定式时,比如 I don't know whether to accept the invitation.
3、当用if会引起歧义时,因为if可作如果讲,所以如果用if句子会发生歧义时只用whether.
4、介词后面跟whether,比如:They are talking about whether the sports meeting will be put off.
关系代词:who,whom,whose,which,whoever,whichever等
如:He asked me who was talking to me the other day.
They didn't know whose phone was on the table.
关系副词:where,when,why
如:I was wondering where we can get enough money.
Please tell me when you will arrive.
以how开头的词组,如how often,how long,how far,how many..
如:Could you please tell me how many apples are in the box.
还有注意形式宾语,一般出现在复合宾语中,也就是有宾语补足语的时候,
如:I think it strange that he has failed the exam.
最后还要注意宾语从句中的时态问题,就是说如果主句时态是现在时(一般现在时,现在进行时,或者现在完成时)时,从句时态不受影响;如果主句时态是过去时(一般过去时,过去进行时,过去完成时),从句时态要后退一步,也就是一般现在时退为一般过去时,一般过去时退为过去完成时.
当然还有宾语从句中的虚拟语气了.
全部手打的哦,今天下午刚跟学生讲,所以当自己复习一遍,不懂欢迎再问.
