一般過(guò)去時(shí)
一、謂語(yǔ)動(dòng)詞是be動(dòng)詞
1.意義:表示過(guò)去存在的某種狀態(tài)
2.結(jié)構(gòu):
肯定:主語(yǔ)+be(was,were)+其他
否定:主語(yǔ)+be+not+其他
一般疑問(wèn)句:Be+主語(yǔ)+其他?
Tips:單數(shù)was,復(fù)數(shù)were
Eg:I was a student.(肯定)
I was not a student.(否定)
Were you a student?(一般疑問(wèn)句)
She was a beautiful girl.(肯定)

2. 結(jié)構(gòu):
肯定:主語(yǔ)+動(dòng)詞過(guò)去時(shí)+其他
否定:主語(yǔ)+didn’t+動(dòng)詞原形+其他
一般疑問(wèn)句:
Did+主語(yǔ)+動(dòng)詞原形+其他?
特殊疑問(wèn)句:特殊疑問(wèn)詞+一般疑問(wèn)句
Tips:
肯定句變否定句和一般疑問(wèn)句步驟口訣:
有情有be直接用,無(wú)情無(wú)be找助動(dòng)
3. 肯定句變否定句步驟:
有情有be直接用,無(wú)情無(wú)be找助動(dòng)
(1)先看句子是否有be動(dòng)詞和情態(tài)動(dòng)詞
(2)如果有be動(dòng)詞和情態(tài)動(dòng)詞,變否定句,直接在其后加not
(was not=wasn’t,were not=weren’t)
(3)如果沒(méi)有情態(tài)動(dòng)詞和be動(dòng)詞,變否定句,要借助助動(dòng)詞did
(4)助動(dòng)詞加not后,放在主語(yǔ)后,實(shí)意動(dòng)詞前,動(dòng)詞要恢復(fù)原形
(did not=didn’t)
4.肯定句變一般疑問(wèn)句步驟:
有情有be直接用,無(wú)情無(wú)be找助動(dòng)
(1)先看句子是否有be動(dòng)詞和情態(tài)動(dòng)詞
(2)如果有be動(dòng)詞和情態(tài)動(dòng)詞,變一般句,把be動(dòng)詞提前,如果有第一人稱,要變成第二人稱。
(3)如果沒(méi)有情態(tài)動(dòng)詞和be動(dòng)詞,變一般疑問(wèn)句,要借助助動(dòng)詞did
(4)助動(dòng)詞放在句首,如果有第一人稱,要變成第二人稱,注意動(dòng)詞要恢復(fù)原形
Eg:He went shopping yesterday(肯定)
He didn’t go shopping yesterday(否定)
Did he go shopping yesterday(一般疑問(wèn)句)
Yes,he did. No,he didn’t
5. 動(dòng)詞原形變動(dòng)詞過(guò)去式規(guī)則
(1)一般情況下在動(dòng)詞后直接加ed
(2)以不發(fā)音的e結(jié)尾的動(dòng)詞直接加d
(3)以輔音字母加y結(jié)尾的變y為i加ed
(4)以重讀閉音節(jié)結(jié)尾的輔元輔結(jié)構(gòu)雙寫尾字母加ed
(5)不規(guī)則變化需要特殊記
三、時(shí)間標(biāo)志詞
yesterday系列:yesterday morning,yesterday afternoon...
last系列:last night,last year,last week
ago系列:three days ago,a year ago,some days ago
In+過(guò)去年份:in 1990,in 2008
其他:just now,at that time,in the past,a long time ago
