7、类重点的状语从句内容需要大家掌握。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

8、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

9、，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

10、好，我们会在户外野餐。Unless you work hard, you wont succeed.(=If you dont work hard, you wont 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 didnt go to school because I was ill.因为我病了，所以没有去上学。As it

11、 is raining heavily, we wont go to the park.由于雨下得很大，我们就不去公园了。Since everyone is here, lets begin our meeting.既然大家都到了，让我们开始我们的会状语从句中的时态呼应问题尽管状语从句种类较多,但由于状语从句与汉语结构和用法相似,所以理解和掌握它并不难！1.当主句为将来时态或具有将来意义时，时间状语从句和条件状语从句通常要用一般现在时表示将来意义，而不能直接使用将来时态。如：Iwilltellhimassoonashearrives.他一来我就告诉他。Callhimifthemanagerdo

12、esntwakeupintime.你们经理到时醒不来,就叫醒他。注：有时也可见到ifyouwill这样的说法，但那不是将来时态，而是表示意愿或委婉的请求(此处的will是情态动词)。如：Ifyouwillwaitforamoment,Illgoandtellthemanagerthatyouarehere.请等一下，我去告诉经理说你来了。2.与since从句搭配的主句的时态通常是现在完成时态。如：Hehaslivedheresince1999.自1999年以来，他就一直住在这儿。WherehaveyoubeensinceIlastsawyou?自我上次见到你之后你到哪里去了?注：在特定的语言环

13、境中有时也可能用过去完成时或一般现在时。如：Itseemslikeyearssincewelastmet.我们似乎几年未见面了。YesterdayhetoldmethathehadnteatenanythingsinceTuesday.他昨天告诉我自星期二以来他一直未吃任何东西。状语从句中的省略问题1. 在when,whenever,while,until,as soon as等引导的时间状语从句中,可以省略与主句中主语相同的主语和系动词或助动词。When (he was) a child he ran wild. 他小的时候很不守规矩。They were scolded whenever (
