问题: 走一走,瞧一瞧,这里的东西最好看!

whether与if有什么区别?

解答:

1.if 可以引导条件状语从句,而whether 不可以。
2。whether 可以引导所有的名词性从句,而且可以与 or (not) 连用;if 只能引导宾语从句,而且不可以与 or (not) 连用。
eg. If you can do it by yourself, your parents will let you go there alone.
They asked whether (if) we should need any help.
I don't know whether I should take his advice or not.

这样说清楚吗?希望对你有帮助。
