条件状语从句
【常考知识点详解】
1. 当谈论客观真理和普遍现象,表示肯定会发生的结果时,主句和从句都用一般现在时。此时if可用when来代替。如:
If / When you mix yellow and blue,you get green. 如果你将黄色和蓝色混合,便会得到绿色。
2. unless和if … not引导的条件状语从句可以互换。它们引导的从句通常不用将来时,在需要表达将来含义的时候,常用一般现在时。如:
Unless you have a better idea, I' ll take his advice. =If you do not have a better idea,I' ll take his advice.除非你有更好的主意,否则我将采取他的建议。
