3、if引导的条件状语从句与主句的时态:主三从现
1)主将从现:如果主句是一般将来时,从句则用一般现在时表将来。
例:If it rains tomorrow,I will stay at home.
2) 主情从现:主句含有must,may,can等情态动词,从句用一般现在时表将来。
例: You must stop if the traffic light is red.
3)主祈从现:如果主句是祈使句,从句用一般现在时表将来。
例:Please put up your hands if you have any questions.

7、if引导的条件状语从句可与“祈使句+and/or+简单句”互换。
If you work harder, you’ll pass the exam. = Work harder,and you’ll pass the exam.
If you don’t hurry up, you’ll be late. = Hurry up, or you’ll be late.
练习:《同步练习册》P35 Ⅲ题。
注意:如果if 引导的从句中用了will,那么will在此处不是助动词,而是情态动词,表示意愿。
例:If he will pay,I’ll go to the movies with him.

Let sb. do sth. 如sb. 后用了by, in, out等adv.时,可以省略v.
let me get in=let me in, let me pass by= let me by让我过去
如有时间状语,则动词不可省。We let him (come )in.(可省) 12999
