2023年初中英語過去完成時結(jié)構(gòu)及用法詳解

過去完成時

標志：had + 動詞的過去分詞

1. 表示在過去的某個時間或動作以前已經(jīng)發(fā)生的動作或已經(jīng)存在的狀態(tài)。如：

By the end of last week he had finished the work.

He had left when I arrived.

2. 表示從過去某一時間開始，一直延續(xù)到過去另一時間的動作或狀態(tài)。如：

We had not seen each other since I left Beijing.

The film had been on for 5 minutes when I got to the cinema.

3. 某些表意向的動詞(如intend, think, plan, expect, hope等)的過去完成時表示主語未曾實現(xiàn)的愿望、希望、打算。如：

I had intended to visit you last night, but someone called and I couldn’t get away.

We had hoped that you would come, but you didn’t.

4. (虛擬語氣)在條件狀體從句或wish / would rather等后面的從句中，使用過去完成時表示與過去事實相反的主觀愿望。如：

The party wouldn’t have been so perfect if you hadn’t come.

I wish I had gone with you to the concert that day.

5. 過去完成時與一般過去時

1) 基本區(qū)別：過去完成時表示以過去某時間為起點以前所發(fā)生的動作或存在的狀態(tài)，即過去完成時強調(diào)“過去的過去”，而一般過去時只表示以現(xiàn)在時間為起點以前所發(fā)生的事情或存在的狀態(tài)。如：

He studied there two years ago.他兩年前在那兒學習(離現(xiàn)在兩年)

He said he had studied there two years before.他說他兩年前在那兒學習過。(離他說話時兩年)

2) 特別注意：兩個動作如果按順序發(fā)生，又不強調(diào)先后，或者用then, and, but等連詞連接時，多用一般過去時。如：

When she saw the mouse, she screamed.

My aunt gave me a hat and I lost it.
