英語動詞時態學習——比較since和for
Since 用來說明動作起始時間,for用來說明動作延續時間長度。
I have lived here for more than twenty years.
I have lived here since I was born..
My aunt has worked in a clinic since 1949.
Some new oilfields have been opened up since 1976.
I have known Xiao Li since she was a little girl.
My brother has been in the Youth League for two years.
I have not heard from my uncle for a long time.
注意:并非有for 作為時間狀語的句子都用現在完成時。
I worked here for more than twenty years.
(我現在已不在這里工作。)
I have worked here for many years.
(現在我仍在這里工作。)
小竅門: 當現在完成時+一段時間,這一結構中,我們用下面的公式轉化,很容易就能排除非延續動詞在完成時中的誤使。
1、(對) Tom has studied Russian for three years.
= Tom began to study Russian three years ago, and is still studying it now.
2、(錯) Harry has got married for six years.
= Harry began to get married six years ago, and is still getting married now.
顯然,第二句不對,它應改為 Harry got married six years ago. 或 Harry has been married for six years.
