It's said that our school will move to the suburb.I have a doubt____ the news is true. 这里为什么不能填if 只能填whether?

解答
在引导主语从句、表语从句、同位语从句时一般用whether不用if.如: ⑴Whether it is true remains a question.(主语从句)那是不是真的还是个问题. ⑵The question is whether it is true.(表语从句)问题是是不是真的. ⑶We have a doubt whether it is true.(同位语从句) 我们怀疑那是不是真的. 注:whether引导主语从句放在主句之后时可用if来代替.
