1、 单元语法精讲if引导的条件状语从句 条件状语从句是在复合句中作条件状语的句子。表示假如有从句的动作发生就会有主句的动作发生。 条件状语从句常由附属连词if引导。一、位置if引导的条件状语从句，既可放在主句之前，也可放在主句之后。当从句置于主句之前时，常用逗号 与主句隔开。如：You will catch the bus if you get up early. = If you get up early, you will catch the bus.如果你早起的话，就能赶上公共汽车。二、时态应遵循主、从句时态相呼应的原那么。当主句是一般将来时(包含祈使句和含情态动词can, may mus
2、t 等的句子)时，从句要用一般现在时。如：You must see the doctor if you are ill.如果你生病了，你必须去看医生。You will be late for school if you get up late.如果你起晚了，你上学将迟到。三、考前须知1 .在if引导的条件状语从句中，当主句是一般将来时时，不能够使用be going to结构，而要用wilL 如：11 help you with your English if 1 am free tomorrow.如果明天我有空，我会帮你学英语。2 .在if引导的条件状语从句中不能够使用some,而要用any。
