1.定义：if引导的条件状语从句表示假如从句的动作发生，主句的动作就（不）会发生。
2.原则：在含有if引导的条件状语从句的复合句中，主句和从句在时态上通常遵循以下原则：
（1）主句用一般将来时，if从句用一般现在时表示将来。
If Sam doesn’t work hard, he will fail his exams.
（从句）一般现在时 （主句）一般将来时
（2）主句是祈使句或含有情态动词的句子，if从句用一般现在时。
If you want to lose weight, stop eating so much meat.
Presentation
if可以放在句首，也可以放在句中。放在句首时，要用逗号与主句隔开。
