中考英语知识点：条件状语从句
(1)条件状语从句通常由if,unless引导。例如：
Whatshallwedoifitsnowstomorrow?
Don’tleavethebuildingunlessItellyouto.
(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’llhelpyouwithyourEnglishifamfreetomorrow.
Hewon’tbelateunlessheisill.
(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：
Hurryup,oryou’llbelate.
=Ifyoudon’thurryup,you’llbelate.
Studyhardandyouwillpasstheexam.
=Ifyoustudyhard,youwillpasstheexam.
