引导宾语从句,一般既可用whether也可用if.但是有几类特殊情况。
  1 、or not放在whether之后时,只能用whether不用if.
        2、在强调任意选择时,用whether…or,不能用if.
        3、引导宾语从句,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.
        4、从句作介词宾语时只用whether不用if.
        5、作动词的宾语时,用whether不用if.
        6、句子中有if引导的条件句,如再有表示“是否”的宾语从句,用whether不用if.
        7、句子容易产生歧义时用whether不用if来表示“是否”.
         8、如果宾语从句为否定句时,则只用if不用whether.
二、引导主语从句、表语从句、同位语从句时一般用whether不用if.
三、用在动词不定式之前时用whether不用if.
