一般過去式 表示過去的動作和狀態(tài)。
I met him yesterday. 昨天我碰見了他。
一般過去時的構(gòu)成如下:
肯定式 疑問式 否定式 疑問否定式
I worked Did i work? I didn't work Did i not work?
He(she it) Did he (she it) He(she it) Did he(she it)
worked work? didn't work not work?
We worked Did we work? We didn't work Did we not work?
You worked Did you work? You din't work Did you not work?
They worked Did they work? They didn't work Did they not work?
一般過去式構(gòu)成: 表示一般過去式的動詞通常用動詞的過去式形式來表示,而動詞的過去式是在動詞原形的基礎(chǔ)上變化的。動詞的過去式可分為規(guī)則動詞和不規(guī)則動詞。規(guī)則動詞的過去式變化如下: 一般情況下,動詞詞尾加 -ed 。
worked, played, wanted, acted
以不發(fā)音的 -e 結(jié)尾動詞,動詞詞尾加 -d。
Lived, moved, decided, declined, hoped, judged, raised, wiped
以輔音字母 + y結(jié)尾的動詞,把-y變?yōu)?i 再加-ed。
studied, tried, copied , justified, cried, carried, embodied, emptied
以一個輔音字母結(jié)尾的重讀閉音節(jié)動詞,雙寫詞尾輔音字母,再加 -ed。
stopped, begged, fretted, dragged, dropped, planned, dotted, dripped
不規(guī)則動詞的過去式變化規(guī)律性不強(qiáng),須多加記憶。
go - went, make - made, get - got
buy - bought, come - came, fly-flew
其結(jié)構(gòu)是"主語+動詞的過去式"。be動詞的過去式為was, were;行為動詞的過去式有規(guī)則變化和不規(guī)則變化兩種,規(guī)則變化有以下幾種情況:1)直接在動詞原形末尾加-ed. e.g. work-----worked; ask------asked; 2)以e結(jié)尾的動詞只加-d. e.g. arrive-----arrived; like-----liked.3)末尾只有一個輔音字母的重讀閉音節(jié),應(yīng)先雙寫這個輔音字母,再加-ed. e.g. shop-----shopped; 4)以"輔音字母+y"結(jié)尾的動詞,先把y變成i,再加-ed. e.g. carry----carried; study------studied.有些動詞變過去式是不規(guī)則的,e.g. fly------flew; break-----broke; teach-----taught. 這些需要象生單詞一樣記住.
其句式變化分為兩種情況1)含有be動詞的依然在be上做文章. e.g. I was born in 1980. I was not born in 1980. Were you born in 1980? 2)含有行為動詞的變否定句要在行為動詞前加助動詞didn't.,同時把動詞變成原形; 變一般疑問句,在句首加助動詞did,同時把動詞變成原形. e.g. I bought a gift for my mum yesterday. I didn't buy a gift for my mum yesterday. Did you buy a gift for your mum yesterday?
一般過去式的用法:
1) 表示過去某一時刻或某一段時間內(nèi)所發(fā)生的動作或情況,通常一般過去式帶有表示動作時間狀語的詞,詞組或從句,如:a minute ago, yesterday,last week,in1900,during the night,in those days,the other day(前幾天)、once up on a time(過去曾經(jīng))、 just now(剛才)、in the old days(過去的日子里)、before liberation(解放前…)、 When I was 8 years old(當(dāng)我八歲時…)
等。用一般過去時的時候,要表示“過多少時間之后”一般用after,不用in
如: Tom suddenly fel ill yesterday
Tom 昨天突然生病了。
She didn't look well when i lat saw her
我上次看見她的時候,她臉色不好
2.一般過去時也可與 today,this week,this month ,this year 等時間狀語連用。但是這些時間狀語必須指過去,決不包括“現(xiàn)在”在內(nèi)
如: Did you see him today?
今天你見過他了嗎?
(today實(shí)際上指的是今天的過去某一時刻)
3.一般過去時雖不可以與now連用 ,但卻可以和just now(剛才)連用。
如:He went out just now
他剛出去了
4.一般過去時表示過去的時候還有以下一些情況
、伲河糜趕ince從句,主句的謂語動詞如果用現(xiàn)在完成時。其后接的since引導(dǎo)的從句一般須用一般過去時
如:It's been over a year since i came back from the countryside
我從鄉(xiāng)下回來已經(jīng)一年了
(主句的謂語動詞 has been 也可以改為 is 但美國英語多用現(xiàn)在完成時)
②:時間狀語可以省略,前面說過一般過去時常與表過去的時間狀語連用,但下面一些情況下,時間狀語可以省略---從上文可以清楚地看出來時間狀語
如:Did you sleep well?
---前文如有現(xiàn)在完成時所引導(dǎo)時
如:I have been within an inch of life ,and didn't know it!
---和現(xiàn)在時態(tài)對比時候
如: He is no longer the man he was
---有表示過去習(xí)慣的used to 時候
如:I used to play football in the street
、:所表的動作已經(jīng)完成
如:I read a book last week
上星期我讀了一本書
、埽 表示死者的動作和狀態(tài)。在英語中。說道死去的人的時候,一般用過去時表示
如: Who is the man in the picture? 照片上的人是誰?
He was my father. 他是我父親
、荩 有感情色彩的時候如:You asked for it!
你這是自找!
5表示過去一段時間內(nèi)經(jīng);蚍磸(fù)的動作
常與always,never等連用。
Mrs. Peter always carried an umbrella.
彼得太太過去老是帶著一把傘。
(只是說明她過去的動作,不表明她現(xiàn)在是否常帶著傘。)
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.
比較
Mrs. Peter always carries an umbrella.
彼得太太老是帶著傘。
(說明這是她的習(xí)慣,表明她現(xiàn)在仍然還習(xí)慣總帶著一把傘)
I never drank wine.我以前從不喝酒。
(不涉及到現(xiàn)在,不說明現(xiàn)在是否喝酒)
6)句型:
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"
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。
would (had) rather sb. did sth. 表示'寧愿某人做某事'
I'd rather you came tomorrow.
7) 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。
