重点语法if引导的条件状语从句

（时间：60分钟，满分：100分）

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。条件状语从句常由连词if引导。

(一)连接词if

if如果，是引导条件状语从句的连接词，表示主句中动作发生的条件。

☞ If you get up early, you will catch the bus. 如果你早起的话，就能赶上那班公共汽车。

☞ You must see the doctor if you are ill. 如果你生病了，就必须去看医生。

(二)if引导的条件状语从句的构成

构成方式为＂主句+if引导的条件状语从句＂或＂if引导的条件状语从句+主句＂。在含有条件状语从句的复合句中，如果主句在前，从句在后，主从句之间不用标点；如要强调从句的内容，则把从句放在主句的前面，这时主从句之间要用逗号隔开。

☞ I will go to his birthday party if he invites me.

=If he invites me, I will go to his birthday party. 如果他邀请我，我会去参加他的生日聚会。

(三)if引导的条件状语从句的时态

在一般情况下，如果主句表示将来的意义，从句用一般现在时表将来。常见的有以下几种：

☞ You will be late for school if you get up late. 如果你起晚了，上学将会迟到。

☞ If it rains tomorrow, we won’t go to the Great Wall. 如果明天下雨，我们就不去长城。
