中考网整理了关于中考复习知识点之条件状语从句，希望对同学们有所帮助，仅供参考。 条件状语从句 (1)条件状语从句通常由 if ，unless引导。例如: What shall we do if it snows tomorrow? Don't leave the building unless I tell you to. (2)在条件状语从句里,谓语动词通常用现在时态表示将来的动作或状态。例如: I'll help you with your English if I am free tomorrow. He won't be late unless he is ill. (3)祈使句+and(or)+陈述句在意思上相当于一个带有条件状语从句的复合句。例如: Hurry up, or you'll be late. =lf you don't hurry up, you'll be late. Study hard and you will pass the exam. =If you study hard, you will pass the exam.
