since 作連詞引導時間狀語從句的用法。
一、若since 引導狀語從句的謂語動詞是終止性的過去時，則從句
表示的時間是“從動作開始的那一刻起”。如：
he has studied very hard since he came to our school.
自從她來到我們學校，他學習就非常努力。
二、若since 引導的狀語從句的謂語動詞是持續性動詞或表示狀態的動詞的過去時時，
則從句表示的時間是“從那持續動作或狀態結束時算起。”如： i haven’t head any noise since i slept.   sleep 為持續性動詞，sleep 的動作結束時，即“醒來”時，這句應譯為“我醒后還未聽到任何聲音”。how long is it since you lived in shanghai?你離開（沒住在）上海多久了？
?比較 ：he has written to me frequently since i was ill .
自從我病愈以來，他屢次給我寫信。（從句謂語為狀態動詞）
he has written to me frequently since i fell ill.
自從我生病以來，他就屢次給我寫信。（從句謂語為終止性動詞）
三、若 since 引導的狀語從句的謂語為持續性動詞的現在完成時，則表示動作和狀態延續到現在（說話時刻），其表示的時間的起點應從動作的發生時算起。如：
i haven’t heard from him since he has lived there.這里has lived 表示動作的持續性，時間的起點應從：“開始居住” 時算起。因此此句可理解為“自從他（開始）住在那兒起，我就一直沒收到他的來信。”
試比較：1).since i’ve been at this school , we have had three headmasters.自從我來到這個學校已經換了三個校長了。
since i was at this school , we have had three headmaster.
自從我來到這所學校，我們已經換了三個校長了。
2).he has never been to see me since i have been ill.
自從我生病以來，他從未來看過我。
he has never been to see me since i was ill.
自從我病愈以來，他從未來看過我。
由此可見，since 引導的從句持續動詞的一般過去時和現在完成時所表示的意思恰好相反。換言之，前者以肯定的語法形式反映著否定的邏輯內容，而后者的形式與內容是一致的。
至于it is + 一段時間+since…的句型與it has been +一段時間+since…意思相同。前者是規范說法，后者是口語說法。
