中考網(wǎng)整理了關(guān)于2021年中考英語考點:狀語從句中過去完成時,希望對同學(xué)們有所幫助,僅供參考。
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(fā)生有先后關(guān)系,動作在前的,要用過去完成時,動作在后的要用一般過去時。
When I got to the station, the train had already left.
After he had finished his homework, he went to bed.
注意:before, after 引導(dǎo)的時間狀語從句中,由于 before 和 after 本身已表達(dá)了動作的先后關(guān)系,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:
Where did you study before you came here?
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(jù)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.
用法
1. 過去完成時表示一個動作或狀態(tài)在過去某一時間或動作之前已經(jīng)完成或結(jié)束,即發(fā)生在“過去的過去”。
When I woke up, it had stopped raining.
我醒來時,雨已經(jīng)停了。(主句的動作發(fā)生在“過去的過去”)
2. 過去完成時是一個相對的時態(tài),表示的是“過去的過去”,只有和過去某一時間或某一動作相比較時才使用它。
He told me that he had written a new book.
(had written 發(fā)生在 told 之前 )
3. 過去完成時需要與一個表示過去的時間狀語連用,它不能離開過去時間而獨立存在。此時多與 already , yet , still , just , before , never 等時間副詞及 by , before , until 等引導(dǎo)的短語或從句連用。
Before she came to China, Grace had taught English in a middle school for about five years.
Peter had collected more than 300 Chinese stamps by the time he was ten.
4. 過去完成時表示某一動作或狀態(tài)在過去某時之前已經(jīng)開始,一直延續(xù)到這一過去時間,而且動作尚未結(jié)束,仍然有繼續(xù)下去的可能。
By the end of last year, he had worked in the factory for twenty years.( had worked 已有了 20 年,還有繼續(xù)進行下去的可能)
