初中英语状语从句讲解及专项练习

状语从句指由句⼦来作状语。它可以修饰谓语、⾮谓语动词、定语、状语或整个句⼦。根据其作⽤可分为时间、地点、原因、条件、⽬的、结果、让步、⽅式和⽐较等从句。状语从句⼀般由“主句+连词+从句”或者“连词+从句，主句”。

⼀、时间状语从句：由when，before，after，as soon as，since，until，not…until引导。1. Mozart started writing music when he was four years old.

当莫扎特4岁的时候，就开始写⾳乐作品。2. He went home after he finished his homework yesterday.

他们⼀直⾛到天⿊。6. Xia o ming didn’t leave home until his father came back.

⼩明直到他爸爸回来才离开家。

⼆、条件状语从句：由连词if, unless (=if not) 引导。1.I f it doesn’t rain tomorrow, we will go fishing.

如果明天不下⾬, 我们就去钓鱼.2.You will get good grades if you study hard.

如果你不马上⾛,你将会迟到的.(=I f you don’t leave at once, you will be late.)(主将从现)：在条件状语从句中, 当主句是将来时的时候,从句要⽤⼀般现在时.

既然⼤家都来了, 让我们开始开会吧.3. As it’s December, it is so sold..既然是12⽉份了，那就该冷了。..难点——在语⽓上，because 最重, 表⽰的是直接理由,回答why 时只能⽤它；其次是since, as ,⼀般不表⽰原因, ⽽是表明理由, 进⼀步说明.(译为：由于，既然).

四、地点状语从句：由连词where引导.1.where there is a will , there is a way.
