答
含义上无区别但是用法上还是有的determine whether 后面可以跟 or not 但是 determine if不可以.
有5种情况表示是否 if 不能换whether
1.句中有 or not.
2,引导主语从句,表语从句,同位语从句时.whether it is true remains a question.
3whether+ to do
4 介词+whetherthe question of whether i 'll go back home is still unknown
5做discuss等词的宾语 we discuss whether we should go home.
另外if还有假如 如果 的意思.
