八.时间、条件、原因状语从句
状语从句指在句子中用作状语的从句。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等九种状语从句。
初中阶段,我们学习的状语从句主要有时间状语从句、条件状语从句和原因状语从句,今天我们就来学习以下这三种状语从句。
一. 时间状语从句
主要连词:when、while、as、as soon as(一......就......)、before、after、since等。
【注意1】时间状语从句要符合“主将从现”的原则:即主句用一般将来时,从句用一般现在时。例如:
I will call you as soon as I arrive in Beijing.
我一到北京就给你打电话。
I will give you a call when I arrive at London.
我到伦敦后会给你打电话。
【注意2】since 的用法: since引导的时间状语从句必须是一般过去时,其主句必须时现在完成时。例如:
Since I came to Beijing, I have lived here.
自从我来到北京,我一直住在这里。
【注意3】while 引导的时间状语从句中,谓语动词必须时持续的; when 引导的时间状语从句中,谓语动词可以持续也可以不持续。例如:
While I was away last summer, my dog was taken good care of.
我去年夏天离开的那段日子里,我的狗被照顾的很好。
When I lived in that small village,I often went to play in the field.
当我住在那个小山村的时候,我经常去地里玩耍。
When the film ended,all the people began to go out of the cinema.
电影结束后,所有的人都开始走出电影院。
二. 条件状语从句
主要连词:if, unless(除非=if...not...), as long as(只要)等。
【注意】条件状语从句要符合“主将从现”的原则:即主句用一般将来时,从句用一般现在时。例如:
If it is fine tomorrow,we will have a picnic outdoors.
如果明天天气好,我们会在户外野餐。
Unless you work hard, you won't succeed.(=If you don't work hard, you won't succeed.)
除非你努力工作,否则你不会取得成功。
As long as you go, I will go.
只要你去,我就会去。
三. 原因状语从句
主要连词:because, as(由于), since(因为,既然)等。
【注意】because 引导的原因是未知的原因,as和since引导的原因是已知的原因。例如:
I didn't go to school because I was ill.
因为我病了,所以没有去上学。
As it is raining heavily, we won't go to the park.
由于雨下得很大,我们就不去公园了。
Since everyone is here, let's begin our meeting.
