since從句是成考英語考試中常考的知識點之一,掌握since從句的用法非常重要。那麼關於成人大學聯考英語since從句的用法有哪些呢?下面本站小編爲大家整理的成人大學聯考英語since從句的用法,希望大家喜歡。
成人大學聯考英語since從句的用法1. Since從句爲非延續性動詞的過去時或現在完成時,時間的起點應該從從句動作完成時刻算起。
例如:
Things have changed a lot since I wrote to you last time.
自我上次給你寫信之後,情況已發生了很大的變化。
She has lived with us since she has come here.
自從她來到這裏,就一直和我們住在一起。
2. Since從句爲延續性動詞的一般過去時,表示動作或狀態的結束。其含義與動詞的詞義恰好相反,具有否定意味。
例如:
All has changed since he was at home.
自從他離開家以後,這裏的一切都變了。
I haven’t written to her since she lived in London.
自從離開倫敦以來,我還沒有給她寫過信。
He has never been to see me since I was ill.
自從我病癒以來,他一直沒有來看我。
Two years have passed since I last smoked.
我戒菸已經兩年了。
但如果since從句是延續性動詞的現在完成時,則表示動作由開始延續至說話的時候,具有肯定意味。
例如:
He has never been to see me since I have been ill.
自從我生病以來,他一直沒有來看我。
She has talked little since she has stayed at home.
自從她呆在家裏以後,就很少講話。
Since we have owned a car, we have gone camping every year.
自從我們有了汽車後,年年都去野營。
3. 在現代英語中,since從句是延續性動詞的一般過去時,有時候也可以表示肯定意味。此時,多半用ever來加強since的語義。
例如:
She has known me ever since she was a child.
她從小就認識我了。
I have live here ever since I was born.
我生下來就住在這裏。
4. 在it is+時間+since從句結構中,since從句是非延續性動詞的一般過去時,含有肯定意味。
例如:
It is three years since her husband left her.
她丈夫離開她已經3年了。
It is over sixty years since the People’s Republic of China was established.
中華人民共和國已經成立60多年了。
5. 在it is+時間+since從句結構中,since從句是延續性動詞的一般過去時,含有否定的'意味。
例如:
It is three years since she stayed here.
她離開這裏已經3年了。
How long is it since you were a league member?
你退團有多久了?
6. 在it is+時間+since從句結構中,since從句是現在完成時或過去完成時,均含有否定意味。
例如:
It is five years since we have seen her.
我們已經5年沒有見她了。
It was years since I had seen her.
在那之前,我已經有好久沒有見到她了。
It’s been a long time since I’ve seen you.
我已經很久沒有見到你了。
另外,①根據英語慣用法,since從句不可以否定形式出現。
例如:
It is four years since I have smoked a cigarette. 我已經4年不抽菸了。
不可說:It is four years since I haven’t smoked a cigarette.
但由於下句中的since不作“自從”解,所以從句可以用否定形式。
例如:
I haven’t been out anywhere since I don’t know how long.
也不知多久了,我哪兒也沒去過。
②Since從句通常不與非延續性動詞的現在完成時的肯定式連用。
例如:
Her mother died when she was a child.
她小時候母親就去世了。
不可說:Her mother has died since she was a child.
③Since前不可加表示時間的詞語,但可以與ago連用。
例如:
She has lived with us since her mother died three years ago.
自從她母親3年前去世,她就一直和我們住在一起。
不可說:She has lived with us three years since her mother died.
④在It was five years ago since his father died. 一句中的since用錯了,因爲在含有ago的時間範疇裏,已經有了從過去的一個時間點以來的時間,即已有了since的時間範疇,所以再用since是多餘的。
改爲:
It was five years ago that his father died.
他父親5年前去世了。
It is five years since his father died.
他父親去世已經5年了。
