whether和if的用法
whether和if的用法具体区别：
1、在引导主语从句、表语从句、同位语从句时一般用whether不用if。
2、引导宾语从句，一般既可用whether也可用if。
3、or not放在whether所引导的'从句句尾，则可以用if来替换。
4、whether和or一起还有“不管”之意，引导让步状语从
5、用在动词不定式之前使用whether不用if。
6、虽引导宾语从句，但为了强调宾语部分，也可把从句放在句首，此时只用whether不用if。
7、从句作介词宾语时只用whether不用if。
用whether不用if:当whether与or not连成个词组时； 在介词后面；在动词不定式之前； 引导主语从句时；在及物动词后的宾语从句中。-般疑问句改成宾语从句就用if和whether, IF不能用于句子中含有or not,而whether可以。
