If引导条件状语从句的用法

◆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。条件状语从句常由从属连词if引导。 ◆if引导的条件状语从句使用须知: 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。例如: 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、从句时态呼应的原则。当主句是一般现在时(包含祈使句和含情态动词can, may, must等的句子),从句也用一般现在时。例如: You must see the doctor if you are ill. 如果你生病了,你必须去看医生。 If you want to go skating, wear warm clothes. 如果你想去滑冰,穿上暖和点的衣服。 一.选择正确答案。 1.
