高二英语 Book 5 Module 5状语从句重难点讲解本模块中我们复习了时间状语从句、条件状语从句和让步状语从句。下面我们来看看这三种从句中需要注意的几点。时间状语从句1. before / since“Itbe+ 段时间+ before.”结构，在肯定句中常译为“多久之后才”；在否定句中常译为“不久之后就如：It will be three years before he graduates from university.It was not long before he found another job.u It is / has been + 一段时间+ since.结构中，since从句的谓语动词多用一般过去时，表示动作或状态的完成，计时的起点是动作或状态完成的那一时刻。在语义上，从句动词为延续性动词时，含有否定的意味；从句动词为非延续性动词时，含有肯定的意味。如：It is 3 years since he were here.（表示“他不在这儿己经 3 年了”）It is 3 years since he stopped smoking.（表示“他不抽烟己经 3 年 了”）2. when / as / while表示“当时”，when引导的从句的动作和主句的动作可以同时发生，也可先后发生，从句中的动词既可以是延续性的，也可以是非延续性的；as, while引导的从句强调主句和从句的动作同时发生，并且从句中的动词通常是延续性的。如：When I lived there, I used to go to the seashore on Sundays.While you were reading the paper, I was working.As the kids walked home, they sang happily.注意：当从句表示“随着”时，连词只能用as。如：As the day went on, the weather got worse.3. till/ until两者都表示“一直到；直到才”，基本上可以互换，但till 一般不位于句首。当表示主句动作延续到某时才停止时，主句用肯定句；当表示主句动作到某时才开始发生时，主句用否定句。如：PH wait here until / till the result comes out.（wait这个动作延续到the result comes out停止，主句用肯定句）I wont leave here until / till the result comes out.（leave这个瞬间动作到the result comes out才发生，主句用否定句）条件状语从句 l.only if意为“只有，只要”，位于句首时句子用倒装结构。如：Only if you put your heart into your work can you realise your dream.2. 引导条件状语从句的从属连词有：if, unless, so / as long as, in case, on conditionthat, suppose / supposing, provided that 等。让步状语从句1. as / though / althoughas引导让步状语从句必须采用倒装结构，常用结构为“形容词、副词、名词（其前不用冠词）、动词+as+主语+其他o though比较口语化，为了强调，从句可以倒装；although比较正式，多用于句首；两者都不与but连用，但可与still,yet, nevertheless 连用。如：Young though / as he is, he runs the company successfully.Though / Although we warned him about the danger of travelling in the forest alone,he went there without telling us.2. no matter +疑问词”或“疑问词+ ever引导让步状语从句，意为“不管；无论 ”，后面用陈述句语序。whether . or，也可表示让步关系，意为“不管还是如：Whatever （= No matter what） you say, he wont believe you.ril not have you worry about her whether shes well or ill.【即学即练】从A、B、C、D四个选项中，选出可以填入空白处的最佳选项。1.
