(1) since后面可以接表示过去的时间点，也可以接表示过去的从句；表示动作或状态从过去某一时间开始直到现在的一段时间。
例如：
Tony has taught English in our school since last year.
自从去年，托尼就在我们学校教英语。

4. 延续性动词与非延续性动词
(1) 延续性动词表示能够延续的动作。短暂性动词表示不能延续的动作，这种动作发生后立即结束。例如：live(延续性动词)；open(短暂性动词)
(2) 短暂性动词在肯定句、疑问句中不能与时间段连用，如become, begin, buy, borrow, arrive, come, die, fall, finish, go, join, leave, marry等。为了表述这种意思，我们常用相应的延续性动词have, keep等来代替非延续性动词。例如：
我买这本书一周了。
I have bought the book for a week. (×)
I have had the book for a week. (√)
