一.要點提示
一般過去時是表示在過去的時間里發(fā)生的動作,動詞用過去式(即動詞-ed形式),動詞過去式的變化規(guī)律:
1 一般動詞詞尾加-ed, 如:walked, looked, finished,
2 以字母e結(jié)尾的動詞后加-d,如:lived, decided, noticed,
3 以輔音字母加y結(jié)尾的動詞,變y為i,再加-ed,如:hurried, carried,
4 以元音字母加一個輔音字母結(jié)尾的重讀閉音節(jié)動詞,先雙寫該輔音字母,再加-ed, 如:stopped, stepped。以上是規(guī)則變化,還有一些動詞的過去式是不規(guī)則變化,
如:do—did, have—had, be—was/were, swim—swam等,參見初一下英語書后不規(guī)則動詞表。
二.用法指南
一般過去時的用法
1)在確定的過去時間里所發(fā)生的動作或存在的狀態(tài)。
時間狀語有:yesterday, last (week, nighr, year?), (an hour?) ago, in 1982, just now等。
Where did you go just now?
2)表示在過去一段時間內(nèi),經(jīng)常性或習(xí)慣性的動作。
When I was a child, I often played football in the street.
Whenever the Browns went during their visit, they were given a warm welcome.
3)句型:
a. It is time for sb. to do sth "到??時間了" "該??了"
It is time sb. did sth. "時間已遲了" "早該??了"
如:It is time for you to go to bed. 你該睡覺了。
It is time you went to bed. 你早該睡覺了。
b. would (had) rather sb. did sth. 表示'寧愿某人做某事' I'd rather you came tomorrow.
4) wish, wonder, think, hope 等用過去時,作試探性的詢問、請求、建議等。
I thought you might have some. 我以為你想要一些。
三.一般過去時的一些特殊用法
1.比較:一般過去時表示的動作或狀態(tài)都已成為過去,現(xiàn)已不復(fù)存在。 Christine was an invalid all her life. (含義:她已不在人間。)
Christine has been an invalid all her life. (含義:她現(xiàn)在還活著)
Mrs. Darby lived in Kentucky for seven years. (含義:達比太太已不再住在肯塔基州。)
Mrs. Darby has lived in Kentucky for seven years.(含義:現(xiàn)在還住在肯塔基州,有可能指剛離去)
2. 注意: 用過去時態(tài)表示現(xiàn)在含義,表示委婉語氣。
1)動詞want, hope, wonder, think, intend 等。
Did you want anything else?
I wondered if you could help me.
2)情態(tài)動詞 could, would.
Cou ld you lend me your bike?
