【小知识】宾语从句if和when的辨析

if和when既可以引导宾语从句，也可以引导状语从句，应注意它们在两种从句中的意思和用法的不同。if和when引导宾语从句时，分别意为“是否”和“何时”，其时态应和主句时态相呼应；它们引导状语从句时，意思分别为“如果，假如”和“当……时候”，当主句时态是一般将来时时，其时态用一般现在时。它们常常放在含有状语从句和宾语从句的题干中进行综合考查。如：

—Do you know when he will come back tomorrow ？你知道他明天什么时候回来吗？
—Sorry，I don't know．When he comes back，I'll tell you．对不起，不知道。当他回来了，我将告诉你。
—I don't know if he will come．我不知道他是否会来。
—He will come if it doesn't rain．如果不下雨，他会来的。
