我们知道,引导宾语从句的wether和if都表示“是否”的含义。在口语中,这两个连接词可以互换。但是,在一些考点中,我们们常常会对连接词whether和if感到疑惑。今天,就给大家简单的总结一下它俩的具体区别:
下列情况下whether不可用if换:
1)引导主语从句置于句首时。
2)Whether后没有单词间隔而直接跟or not时。
I don't know whether or not he will come.
3) whether从句作介词宾语时。
They are talking about whether he will win the game.
Everything depends on whether you agree with us.
4)whether后接不定式时。
I don't know whether to attend the meeting.
5)动词discuss, decide的宾语从句时。
