Question

if 与 whetherHis first question was if Peter had come yet这句话有

Answer 1

没有错误

if和whether引导表语从句

引导表语从句时,一般用whether.例如：

The question is whether they can cooperate with us.问题是他们能否与我们合作.

The question I whether we can get there in time.

有的语法认为if 也可以引导表语从句,例如：

The first question I put to him was whether/if he would do it.

Our only problem is if someone gets that brilliant notion first.

不过,对中学生来说,这种用法还是尽时不时避免为好.
