题目:since的用法
解:since的用法:译作“自从…以来” 织梦好,好织梦
(1)接时间点:如 I have stayed in that country since 1995.要求:谓v.用现在完成时,而且须是延续性动词. copyright dedecms
(2)接一段时间 + ago:如 They have lived in that house since two years ago.要求:谓v.用现在完成时,而且须是延续性动词. 织梦内容管理系统
(3)接时间状语从句:如 I have loved her since I met her last time./ Lily has stayed at home since she left school.要求:主句的谓v.用现在完成时,而且须是延续性动词;从句的谓v.用一般过去时,而且须是终止性动词.
(4)用于句型“It’s / It has been + 一段时间 + since + 时间状语从句”中,译作“自从…以来,已经…(时间)了”.如 It’s / has been three months since he moved to this city.要求:主句的谓v.用一般现在时或现在完成时;从句的谓v.用一般过去时,而且须是终止性动词.
(5)用于句型“一段时间 + has passed since + 时间状语从句”中,译作“自从…以来,…
(时间)已经过去了”.如上个例句还可写成:Three months has passed since he moved to this city.要求:主句的谓v.用现在完成时,而且动词必须是has passed;从句的谓v.用一般过去时,而且须是终止性动词. dedecms.com
(6)注:当since用于否定句时,主句的谓v.可以是终止性动词.如 He hasn’t seen the film since last month. copyright dedecms
(7)相关词组:“从那时起”:ever since、since then、from then on.
注:ever since作为一个词组,放句尾可单独使用.如I have given up smoking ever since.另外,还可在since后接句子.since前加ever,只是加重语气而已.如 I have given up smoking ever since I caught a bad cough. copyright dedecms
(8) since还可引导原因状语从句,译作“由于;因为”,相当于because.如 Since he was lazy,he didn’t finish his homework.

举一反三
例1: since的用法[英语练习题]
思路提示:
since的用法主要有两点:一是表示“自从……以来”,二是表示“既然”之意.但如果只了解词的含义,而不了解其用法,在使用时就会造成错误.例如:I have not heard from him since I lived in Shanghai.
dedecms.com
不少人会望文生义,将该句译为:“自从我住在上海以来,就再也没有收到他的信了.”而实际上这个句子的译文并非如此,那么正确的含义是什么呢?
下面谈谈since作连词引导时间状语从句的用法. 织梦内容管理系统
一、若since引导的状语从句的谓语动词是终止性的过去时,则从句表示的时间是“从动作开始的那一时刻起”.如:
copyright dedecms
He has studied very hard since he came to our school.自从他来到我们学校,他学习就非常努力.
本文来自织梦
We have been missing them since they left here自从他们离开这里,我们就一直很想念他们.
这是最常见的一种用法,此处不再多述. 本文来自织梦
二、若since引导的状语从句的谓语动词是持续性动词或表示状态的动词的过去时时,则从句表示的时间是“从那持续动作或状态结束时算起”.如: 织梦内容管理系统
I haven’t heard any noise since I slept.Sleep 为持续性动词,sleep的动作结束时,即“醒来”时,这句应译为“我醒后还未听到任何声音”.
织梦好,好织梦
John is now with his parents in New York,it is already three years since he was a teacher约翰现在和父母一起住在纽约,他不当教师已经三年了. dedecms.com
本文开始出现的那个句子就可以译为“自从我离开上海,就再也没有收到他的信.”这种译法常被人们误用,我们不妨再多举几个例子看看: dedecms.com
How long is it since you lived in Shanghai?你离开(没住在)上海多久了? 内容来自dedecms
It is half a month since he was a League member.他退团(不当团员)半个月了.
dedecms.com
It’s been quite some time since I was last in London我离开伦敦已很长时间了.
比较:He has written to me frequently since I was ill.自从我病愈以来,他屡次给我写信.(从句谓语为状态动词)
内容来自dedecms
He has written to me frequently since I fell ill.自从我生病以来,他就屡次给我写信.(从句谓语为终止性动词)
内容来自dedecms
三、若since引导的状语从句的谓语为持续性动词的现在完成时,则表示动作和状态延续到现在(说话时刻),其表示的时间的起点应从动作发生之时算起.如:
I haven’t heard from him since he has lived there.
这里has lived表示动作的持续性,时间的起点应从:“开始居住”时算起.因此此句可理解为“自从他(开始)住在那儿起,我就一直没收到他的来信”.
Since we have owned a car,we have gone camping every year.自从我们自己有了汽车,我们每年都去野营. 织梦内容管理系统
试比较:1.Since I’ve been at this school,we have had three headmasters.自从我到这所学校,我们已换了三个校长了. dedecms.com
Since I was at this school,they have had three headmasters.自从我离开这所学校,他们已换了三个校长了. 内容来自dedecms
2.He has never been to see me since I have been ill.自从我生病以来,他从未来看过我. dedecms.com
He has never been to see me since I was ill.自从我病愈以来,他从未来看过我.
织梦内容管理系统
由此可见,since引导的从句持续动词的一般过去时和现在完成时所表示的意思恰好相反.换言之,前者以肯定的语法形式反映着否定的逻辑内容,而后者的形式与内容是一致的. 本文来自织梦
至于It is +一段时间+since…的句型与It has been +一段时间+since…意思相同.前者是规范说法,后者是口语说法. 织梦内容管理系统
应注意的是,在这种结构中,since引导的从句绝对不能用否定式的谓语动词来表示否定意义,下面两句都错了: copyright dedecms
It is a long time since he didn’t study English.
It’s two months since you didn’t come to see me. 本文来自织梦
正确的说法为: 织梦好,好织梦
It’s a long time since he studied English 他好久没学英语了.
You haven’t come to see me for two months.你有两个月没来看我了. 织梦内容管理系统
