since后接延续性与短暂性动词的用法(最新整理)

1、since 后接延续性与短暂性动词的用法一、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：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。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。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”

2、。如：i havent 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”。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。所以， i have not heard from him since i lived in shanghai. 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

3、收到他的信了。”而实际上这个句子的译文是： “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：how long is it since you lived in shanghai?你离开（没住在）上海多久了？it is half a month since he was a league member.他退团（不当团员）半个月了。its 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 il

4、l.自从我病愈以来，他屡次给我写信。（从句谓语为状态动词）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）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 havent 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

5、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。试比较：1. since ive 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。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。2.he has never been to see me since i have be

6、en ill. 自从我生病以来，他从未来看过我。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。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。it has been three years since he worked her. 他不在这儿工作已经三年了it has been three years since he smoked. 他已经戒烟三年了。至于 it is +一段时间+since的句型与 i

7、t 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。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：it is a long time since he didnt study english. its two months since you didnt come to see me. 正确的说法为：its a long time since he studied english 他好久没学英语了。you havent come to see me for two months. 你有两个月没来看我了
