第17章 過去進行時(1 / 2)

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.
