As he grew older, he became less active.特别注意如果主句表示的是非延续性动作，而从句用延续性动词的进行时态表示在一段时间内正在进行的动作,那么when, while与as可互换使用.When/While/As I was walking down the street, I came across an old friend.如何区分when引导的定语从句与when引导的时间状语从句1.结构上的不同假设when引导定语从句,那么when的前面必然有表示时间的名词，即先行词.假设when引导 时间状语从句,那么其前面往往没有表示时间的名词，比方上面例句3中,when前面的tone就 不是表示时间的名词，因此不可能作when的先行词.2. when的作用不同当when引导定语从句时,此时when是指代表示时间的先行词,在定语从句中作时间状 语，修饰从句的谓语.当when引导时间状语从句时,此时when不在从句中作任何成分(比方不是作状语来修 饰从句谓语)，只起连接主句和从句的作用.不过需要注意的是,when引导的时间从句修饰主 句的谓语,作主句谓语的时间状语.因此，我们可以用这样一句话来区分when的两类从句:在when引导的定语从句里，作 从句谓语的状语是when这个词，而在when引导的时间从句里,作主句谓语的状语是when 引导的从句，而不是when这个词.2.表示“一就”含义的词或短语引导的时间状语从句(1)有的名词(短语)或副词可引导时间状语从句，如：the moment, the minute, the second, the instant, immediately, directly, instantly 等，另外 as soon as 也 可引导时间状语从句,从句中用一般时态代替将来时态.For example, the moment you get on the airplane, start adjusting your biological clock to the destination，s time.The boy ran off the minute he saw the owner of the orchard.(2)在hardly/scarcelywhen和no soonerthan.结构中，主句用过去完 成时,than或when所在的从句用一般过去时.1. I had hard 1y told him the news when he stopped listening.2. He had no sooner finished his speech than the students started cheering.特别注意 在hardly/scarcely.when, no soonerthan结构中，当 hardly, scarcely或no sooner位于句首时,主句要用局部倒装.3.They had hardly reached Edinburgh when they were ordered to return to London.=Hardly had they reached Edinburgh when they were ordered to return to London.3. till, , until 和 not . until/tiH 的用法until, till两者均表示“直到为止”，引导时间状语从句.肯定句中，其主句谓 语动词必须为延续性动词，表示某动作一直延续到某时间为止,not.until .， not.till.两者均表示“直到才",not所在的主句的谓语动词必须 为非延续性动词，表示某动作直到某时间才开始.until可用于句首，而tin不可放在 句首,till 一般不用于强调句型.1. The father waited until his daughter hadfinished her homework.2. The baby didn't go to bed until/till his mother returned.4. after,. before引导的时间状语从句after表示“在之后”，before表示“在之前;还没来得及就”.He changed his name after he left his hometown.Before modern medicine changed the laws of nature, many children died of common childhood diseases.特别注意(1) “It will be/was +时间段+before从句”表示“在之前还要 多久/过了多久才”.It will be half a year before I graduate.(2) “It wont be/wasn't +时间段+before从句”表示“过不了多久就/没过 多久就”.It wasn，t long before we started.5. since引导的时间状语从句since意为“自从以来”，从句的谓语动词一般是非延续性动词，主句的谓语动词 一般是延续性动词.since从句的时态假设是一般过去时,主句常用现在完成时或现在完 成进行时.此外,since常用于以下句型：It is/has been+时间段+since从句(常用一般过去时)“It is/has been+时间段+since从句(常用一般过去时)”句型的含义取决于从句 的谓语动词是否为延续性动词.假设从句谓语动词为非延续性动词,那么表示从该动作开 始一直延续到现在多久;假设从句谓语动词为延续性动词，那么表示从该动作结束到现在 多久.They have been friends since they met for the first time in London. 自从在伦敦第一次见面以来，他们一直是朋友.1t is three years since the war ended.战争已经结束三年了.It is three years since he lived here.他不在这里住已经有三年了.6. 其他常见名词短语引导的时间状语从句every time 每次each time 每次any time任何时候next time 下次all the time(在某段时间内)一直the first/last time 第一次/最后一次the day/year 那天/年Every time I meet her I always forget her name.The first time I met her, I thought her nice and honest.(-)条件状语从句1.引导条件状语从句的常见附属连词(短语)有：if, unless, as/so long as, in case (万 一)，once, on condition that, provided/providing (that), supposing/suppose (that), assuming that (假设)等.You11 fail the exam unless you study hard.They agreed to lend us the car on condition that we returned it before the weekend.My parents don，t mind what job I do as long as I am happy.2. only if 和 if only 的区别only if意为“只有”，置于句首时主句的主谓要用局部倒装.if only意为“但愿;要 是就好了”，引导的从句要用虚拟语气:与现在的情况相反时，从句用一般过去时;与过 去的情况相反时,从句用过去完成时;与将来的情况相反时,谓语用“would/could+动词原 形”.Only if he studies harder can he catch up with others.他只有更加努力学习才能赶上其他人.Tf only it would stop raining!但愿雨会停！(三)让步状语从句1. although, though, as与while引导的让步状语从句(1)although引导让步状语从句时，只能用正常语序；though引导让步状语从句时，可 用正常语序，也可用倒装语序;as引导让步状语从句时只能用倒装语序，即从句中的表语、 状语或动词原形置于句首,假设表语是单数名词,前置时要省略冠词.Although/Though he may be troubled, he always presents a calm smiling face.Child as/though he was, he helped me a lot.Try as/though he might, he could not open the door.(2)although 与 though 都可以与 yet, still, nevertheless 连用，但不能和 but 连 用.Although/Though it was raining hard, yet they went on playing football.(3)while引导让步状语从句时,一般置于句首.While I admit that there are problems, I don't agree that they cannot be solved.2. even if与even though引导的让步状语从句even if与even though表示“即使，纵然”，引导让步状语从句时,可用虚拟语气，也 可以用陈述语气.r 11 do it, even if it takes me all the afternoon.Even if I were in your place, I wouldn，t take the job.3. “no matter+疑问词”与“疑问词+ ever”引导的让步状语从句(1) “no matter+疑问词”相当于“疑问词+ ever”，二者都可以引导让步状语从句.Don，t trust him, no matter what/whatever he says.(2)whoever, whatever, whomever, whichever 还可以引导名词性从句，但 “no matter+疑问词”不可以.4. whether.or (not) .引导的让步状语从句Whether . or.表示“不管还是:提供两种比照情况.We 11 go on with the work, whether we can find the necessary tools or not.(四)地点状语从句地点状语从句可用where, wherever, anywhere, everywhere等引导.地点状语从句 可置于句首、句中或句尾.If you happen to get lost in the wild, you'd better stay where you are and wait for help.Wherever she goes, there are crowds of people waiting to see her.特别注意where既可引导定语从句,也可引导状语从句.引导定语从句时,从句前应有 一个表示地点的名词作先行词,where可替换成“介词+which" ；而状语从句前那么无先行词.You'd better make a mark at the place where you have any questions.
