从句中两种时态的不同含义从句中两种时态的不同含义 我们再来分析一下 since 从句中使用终止性动词与延续性动词的区别 在 since 从句中我们往往使用终止性动词的过去时 从句表示的时间是 从那一时刻起 如 Mr Brown has made quite a few Chinese friends since he came to China 布朗先生自 从来中国以后已交了相当多的中国朋友 He has studied very hard since he came to our school 他自从来到我们学校学习一直 非常努力 We have been missing them since they left here 自从他们离开这儿 我们一直非常想 念他们 注意 注意 sincesince 从句中不可以使用终止性动词的完成时从句中不可以使用终止性动词的完成时 since 从句中的谓语动词是延续性动词的一般过去时 从句表示的时间是 从那延续性动词 动作结束时算起 如 It s three weeks since my aunt stayed here My aunt hasn t stayed here for three weeks 我阿姨不在这儿已有三周了 I haven t heard from him since I lived in Shanghai 自从我离开上海以来 一直没 有收到他的来信 但是如果在 since 从句中的谓语动词是延续性动词的现在完成时 则意味着该状态延续至今 和一般过去时的含义完全相反 试比较 I have been at school since I have been ill 我生病以来一直在学校里 I have been at school since I was ill 我病愈以来一直在学校里 弄清 since 从句中两种时态的不同含义 对于以下例句的理解就不会感到困难了 如 It s 4 years since Mr Li smoked 李先生戒烟已有四年了 They asked me to have a drink with them I said that it was at least ten years since I had enjoyed a good drink 他们叫我去喝一杯 我说我至少有十年没痛痛快快地 喝一杯了 I haven t heard from him since I lived in Shanghai 从我离开上海就没收到过他的来 信 4 I haven t heard any noise since I slept 我醒后没听到任何噪音 He has lived with my uncle since he has returned from abroad 误 He has lived with my uncle since he returned from abroad 正 五 终止性在否定句中 因为动作的否定就是一种可以延续的状态 因此 可以和五 终止性在否定句中 因为动作的否定就是一种可以延续的状态 因此 可以和 forfor 或或 sincesince 引导的时间状语连用 也可用在引导的时间状语连用 也可用在 howhow
