過去完成時與一般過去時的區(qū)別
雖然這兩種時態(tài)都表示過去發(fā)生的動作或存在的狀態(tài),但在使用時應注意以下幾點:
1. 時間狀語不同:過去完成時在時間上強調"過去的過去";而一般過去時只強調過去某一特定的時間。試比較:
They had arrived at the station by ten yesterday.
They arrived at the station at ten yesterday.
2. 在沒有明確的過去時間狀語作標志時,謂語動詞動作發(fā)生的時間先后須依據上下文來判斷:先發(fā)生的用過去完成時,后發(fā)生的則用一般過去時。如:
She was very happy. Her whole family were pleased with her, too. She had just won the first in the composition competition.
3. 當兩個或兩個以上接連發(fā)生的動作用 and 或 but 連接時,按時間順序,只需用一般過去時來代替過去完成時;另外,在 before , after , as soon as 引導的從句中,由于這些連詞本身已經表示出時間的先后,因此也可以用過去時來代替過去完成時。如:
He entered the room, turned on the light and read an evening paper.
I (had) called her before I left the office.
