5.見本頁4.第二種情況,時間狀語從句用過去完成時。
6.指主句和從句的行為緊接發生,用一般過去時。
過去完成時的用法:
1過去完成時主要表示過去某一時刻或動作之前,已經發生或完成的動作。它表示的動作發生的時間也可以說:“過去的過去”,如圖:
表示過去某一時間常用以下幾種方式:
①用by,before等構成的介詞短語如:
We had learned twelve English songs by the end of last term.
到上學期末為止,我們學了十二首英語歌曲。
Before supper he had finished his homework.
晚飯前他已完成了家庭作業。
②用when,before等引導的時間狀語從句。如:
They had left when I got there.
當我到那兒時,他們已離去。
We had repaired his bike before he came back.
在他回來之前我們已修好了他的自行車。
③通過上下文。如:
He told me that his father had goo Wuhan.
他告訴我他父親到武漢去了。
The farmens were very happy bebsp;they had got anood harvest.
農民們很高興因為他們又獲得了一個好收成。
2在以when,as soon as,before,after,until等引導的時間狀語從句中,如果從句的行為發生在主句之前,從句則用過去完成時。如:
He felt mubsp;better after he had taken the medie.
從句的行為發生在主句的行為之前.
When we got here, the film had begun.
(從句的行為發生在主句的行為之前)但如果主句的行為和從句的行為緊接發生,則常常不用過去完成時,特別是在含有before,after,as soon as 複合句中。如:
I went out after I said good bye to my mother.
我向母親告別後就走了。
Before I left the classroom I clod the windows.
在離開教室前我關上了窗子。
We began to work in the fields as soon as the rain stopped.
