語法解析 | 過去完成時的判定
有的同學有時候不太能很快速、準確的判斷出句子中的過去完成時用法,下面,小編收集了大量相關知識,今天就給大家講講,如何能判定過去完成時,一起來看看吧!
1. 由時間狀語來判定
一般說來,各種時態都有特定的時間狀語。與過去完成時連用的時間狀語有:
(1 )by + 過去的時間點。如:
I had finished reading the novel by nine o'clock last night.
(2 )by the end of + 過去的時間點。如:
We had learned over two thousand English words by the end of last term.
(3 )before + 過去的時間點。如:
They had planted six hundred trees before last Wednesday.
2. 由“過去的過去”來判定。
過去完成時表示“過去的過去”,是指過去某一動作之前已經發生或完成的動作,即動作有先後關係,動作在前的用過去完成時,在後的用一般過去時。這種用法常出現在:
(1 )賓語從句中
當賓語從句的主句為一般過去時,且從句的動作先於主句的動作時,從句要用過去完成時。在told, said, knew, heard, thought等動詞後的賓語從句。如:
She said that she had seen the film before.
(2 )狀語從句中
在時間、條件、原因、方式等狀語從句中,主、從句的動作發生有先後關係,動作在前的,要用過去完成時,動作在後的要用一般過去時。如:
After he had finished his homework, he went to bed.
注意:before, after 引導的時間狀語從句中,由於before 和after 本身已表達了動作的先後關係,若主、從句表示的動作緊密相連,則主、從句都用一般過去時。如:
After he closed the door, he left the classroom.
(3)表示意向的動詞,如hope, wish, expect, think, intend, mean, suppose等,用過去完成時表示"原本…,未能…"
We had hoped that you would come, but you didn't.
3. 根據上、下文來判定。
I met Wang Tao in the street yesterday. We hadn't seen each other since he went to Beijing.
