掌握whether的用法, 经常要同时注意whether和if的用法区别

一、相同之处。
1.whether和if都能引导宾语从句,常置于see,ask,learn,tell,wonder,doubt,find out等动词之后。
如:He asked me whether/is I could help him. I want to know whether/if he lives there.
2.whether和if都可用it作形式主语从句中。如: it's uncertain whether/if he'll come this evening.
3.在be uncertain/doubtful之后,常用whether引导宾语从句,有时也可以用if,如: We are uncertain whether/if Mary will come.
二、不同之处。
1.whether可置于句首引导主语从句,而if不能。如: ___the 2000 Olympic Games will be in Beijing is not known yet. A.whether B.If C.Whether D.That 答案是C。
2.whether可用在介词之后,引导宾语从句,而If则不能。如: Success depends on whether we make evough effort.
3.whether可引导表语从句,if则不能。如: The question is whether it is not worth doing.
4.在名词之后引导同位语从句时,用whether而不用if。如: The question whether the students answered correctly should be decided by the teacher.
5.whether后可接不定式,而if不能。如: Please tell us whether to go or stay here.
6.在有些动词(如discuss)之后,只能用whether,而不用if引导宾语从句。如: We discussed whether we should close the shop.
7.在引导否定概念in宾语从句时,只能用if,而不用whether.如:he asked me if I hadn't finished my work.
