这题是错的,疑问句从句有or不能用if的

在这种情况下，if 和whether是一样的意思和用法，不是只有如果的意思哦

意思一样后面有or not注意whether和if有三用三不用
1.和or not连用时用whether不用if
2后面加to do的时候用whether不用if
3.前面有介词的时候用whether不用if对啊，根据第一条应该不能用if，可是答案给了相信你已经有了答案熟记这些基本的没有答案是什么啊答案是if和whether都可以…最好用whe~~答案有时会错的whethe...

whether和if都有是否的意思，整句是我不确定，他是否来这儿

意思一样。

whether用在不定式前 介词后 no matter而if用在虚拟语态 条件状语中
