一.条件状语从句:
1 引导条件状语从句的词/短语有:if(如果,假如),unless(除非,如果不),so long as(只要),as long as(只要,如果,万一),suppose(倘若),if only(只要),provide that或providing (that)(假如)。

④ 只要他邀请,我就去那里。
I’ll go there ______________________________.
⑤ 如果天放晴,我们就走。

2 同时间状语从句一样,条件状语从句如果表示将来时间,用一般现在时代替一般将来时。
① 如果你去,我也去。
I’ll go ___________________.
② 除非他明天给我打电话,否则我不会等他。
I won’t wait for him _______________________________.
3 如果从句由if引导,又有系动词be,条件状语从句可用省略形式。
① 可能的话就明天来吧。
Come tomorrow if possible.
② 如果有必要,我就买一台电视机。
