由连词if引导的宾语从句和条件状语从句
1.if引导的宾语从句
I don't know if he will come tomorrow.=I don’t know whether he will come tomorrow.
宾语从句中，当从句的成分完整、意思缺少“是否”之意时，连词可用if;可以和whether互换。
2.if引导的状语从句
If he comes tomorrow,we will play basketball.=We will play basketball if he comes tomorrow.
if意为“如果”，引导条件状语从句时，既可放在主句前面，也可放在主句后面。若if条件句放在句首，从句后面常加逗号与主句隔开。
