过去完成时态

过去完成时态

1.过去完成时态表示的含义：表示一个动作在过去某一时间或动作之前已经发生或完成（既一个动作发

生在过去的过去）。

2.过去完成时态构成形式：had+过去分词

3.过去完成时态的使用范围：

✧出现在主从复合句中，常与that引导的宾语从句连用.

例如：He said that he had never seen such a beautiful place before.(先看见过,再说)

Lucy told me that she had been to Beijing twice.(先去过,再告诉我)

✧出现在主从复合句中，常于when \ before \ after\as soon as 引导的时间状语从句连用.

注意:主句和从句应各自拥有主\谓\宾的结构.

例如: You had cleaned the classroom when I got here.

My mother had cooked supper before I went home.

Mr Liu had taught in the school for 38 years before I came here.

I went to bed after I had finished my homework.

注意: 在以上两种主从复合句中,经常存在两个动作,先发生的用过去完成时态,

后发生的用一般过去时态.

✧出现在简单句中, 常于by(表示在…之前 \ 到…的时候) \ before 构成的时间状语连用.

by, before +过去的时间点；

例如: I had finished my homework by 11 last night.

I had reached school before 7 o’clock this morning.

✧出现在简单句中, 常于by the end of (到…末为止)引导的时间状语连用.

例如:By the end of the match, we had scored 3 goals.

We had learned 1000 English words by the end of last term.(到上学期末为止,既单词是在上学期末之前学的)

✧与by the time (表示在…之前 \ 到…的时候) 构成的短语连用,

例如:By the time we got there, the bus had already gone.(当我们到那的时候, 车已经开走了).

By the time they called, I had left.

✧与as (表示象\ 按照) 引导的从句连用.

例如;We did as he had told us.(我们按照他告诉我们的去做)

5.过去完成时态应注意的几个问题:

●在主从复合句中,如有after, before 引导的时间状语从句,由于从句的动作和主句的动作发生的顺序

已经非常明显,有时可用一般过去时态代替过去完成时态.

例如: He called me after he had come back..=== He called me after he came back.

●对于一连串的过去动作,相互之间衔接十分紧密, 可以全部使用一般过去时态,不用过去完成时态.

例如:He got up at six yesterday, washed, brushed his teeth, went downstairs and then did morning
