Whether与If在用法上的区别
区别不大，都用来引出一个yes/no问题。
例子：
He asked me whether I felt well.
We're not sure if they have decided.
discuss后面通常跟whether。
例子：
We discussed whether he should be hired.
They discussed whether to invest in the new idea.
介词后面只跟whether
例子：
We talked about whether we should go or not.
I looked into whether he should stay.
在不定式前面只使用whether
例子:
She can't decide whether to buy the house or wait.
He considered whether to give up the position or quit next year.
通常来说，我们认为whether比if要正式一些。
例子:
Let me know whether you will be able to attend the conference.
The CEO will decide whether this is a risk worth taking.
还有三个常用的句式：
whether or not
whether ... or
whether ... or not
例子：
There were times when I wondered whether or not we would get there.
She was uncertain whether to stay or leave.
I didn't know whether to believe him or not.
