初中英语――if引导的条件状语从句

在 if 引导的条件状语从句中，if 和条件句位置灵活，可直接放在主句后面，若 if 条件句放句首，从句后面要加逗号，和主句隔开。还要注意前后时态一致原则.引导条件状语从句的连接词主要有：if(如果）、unless（除非）或 as long as（只要）等。unless在意思上等于if...not。

一、条件状语从句用法

1、引导条件状语从句最常用的连词是if,由if引导的条件状语从句表示在某种条件下某事很可能发生。如：

If you ask him, he will help you.

如果你请他帮忙,他会帮你的。

If you fail in the exam, you will let him down.

如果你考试不及格,你会让他失望的。

另外,if从句还表示不可实现的条件或根本不可能存在的条件,也就是一种虚拟的条件或假设,从句多用一般过去时或过去完成时。如: If I were you, I would invite him to the party.

如果我是你,我会邀请他参加聚会。

2、unless = if...not. 除非,若不,除非在……的时候

例如：Let's go out for a walk unl
