1． Be 动词的一般过去时态
在没有实义动词的句子中使用be动词， am is 的过去式为was; are的过去式为were2
构成：肯定句：主语+was (were) +宾语 如：I was late yesterday. （昨天我迟到了。）
否定句：主语+was (were) +not+宾语 如：We weren't late yesterday. (我们昨天没迟到)
疑问句：Was (Were) +主语+宾语 如： Were you ill yesterday? （你昨天病了吗？）
肯定回答： Yes, I was. (是的，我病了。) 否定回答： No, I wasn't. (不，我没病。)
特殊疑问句：特殊疑问词+was (were) +主语+宾语. 如：When were you born? 你是什么时候出生的？ .
2． 实义动词的一般过去时态
肯定句要使用动词的过去式，否定句和疑问句要使用助动词do和 does 的过去式 did.
肯定句为：主语+动词过去式+宾语 如： I went home at nine o'clock yesterday.（我昨天九点钟回的家。）
否定句：主语+didn't +动词原形+宾语 如：I didn't go home yesterday. (我昨天没回家。)
疑问句：Did +主语+动词原形+宾语如： Did you go home yesterday? (你昨天回家了吗？
肯定回答： Yes, I did. (是的，我回了。)否定回答：No, I didn't. (不，我没回家。)
3． 助动词和情态动词过去式如下：
shall―should（将要）用于第一人称单数 will―would（将要）用于所有人称 can ---- could（能，会）
may―might（可以） must―must （必须）have to―had to（不得不）
助动词和情态动词的过去时态要使用他们的过去式，后面的动词还使用原形。
如： I had to do my homework yesterday. (昨天我不得不做作业。)
4．一般过去时态由动词的过去式表示。大多数动词的过去式是在动词原形后加上ed构成。这类动词称为规则动词。
1） 一般情况下在词尾直接加ed。 如：play―played work―worked
2）以e结尾的动词只加d. 如：like--- liked love―loved , g9 N6 q, P ~" w
3） 以辅音字母+Y结尾的动词，变Y为I，再加ed. 如：study―studied carry―carried
4） 以重读闭音节结尾的动词，如果末尾只有一个辅音字母，要双写最后这个辅音字母，再加ed. 如：stop―stopped
5． --ed的读音规则如下：
1）在清辅音后面读[t]. work―worked [wE:kt] help―helped [helpt]
2）在浊辅音或元音后读[d]. learn―learned [lE:nd]
3）在[t] 和[d] 后读[id]. support―supported [sE'pC:tid]支持
6．不以ed 结尾的过去式，称为不规则动词。
不规则动词的过去式：
a.过去式与动词原形的拼写形式相同：let → let, put → put, read → read,(注意read的过去式读[red])
b. i → a: begin → began, drink → drank, give → gave, ring → rang, sing → sang, sit → sat, swim → swam c. i → o: drive → drove, ride → rode, write → wrote
d. ow → ew: grow → grew, know → knew, throw → threw
e. 含ough或augh的：bring → brought, buy → bought, think → thought；catch → caught, teach → taught
f. am is ---was are ---were do---did can---could come---came
不规则动词的过去式平时出现要留心,逐个熟记,注意积累。
三. 句型转化：
1．be 动词的过去时的句型如下：
(1)否定句： 主语 + be动词的过去式（was, were）+ not?
(2)疑问句： be动词的过去式（was, were）+ 主语 ?？
a.He was busy yesterday. (肯定句) 他昨天很忙。 b.He was not busy yesterday. (否定句) 他昨天不忙。
c.Was he busy yesterday? (疑问句) 他昨天忙
d.There weren’t any boys in the room.房间里没有男孩儿。e. Were there any boys in the room? 房间里有男孩儿吗？
2．行为动词的否定式和疑问式：
(1)若肯定句中只有一个行为动词,那就得在行为动词前加上did not或缩略式didn’t,并把这个行为动词由过去式改为动词原形。例如：
a. I called Lin Tao yesterday afternoon. →I did not / didn’t call Lin Tao yesterday afternoon.
b. I borrowed a book from Sun Yang last Sunday. → I didn’t borrow a book from Sun Yang last Sunday.
(2) 行为动词的一般疑问句
若在陈述句中只有行为动词的过去式,那就得在句首加上一个助动词did来帮助提问,然后把句中的行为动词由过去式改为动词原形,并在句末打上问号。回答时别忘了还用did.例如：
a. We stayed there for 10 days last month. → Did you stay there for 10 days last month? Yes, we did. / No, we didn’t.
b. Mary had a delicious dinner yesterday evening. → Did Mary have a delicious dinner yesterday evening? Yes, she did. / No, she didn’
t一般过去时态的“三变”技巧
_一变：肯定句变为否定句
【技巧1】当句中含有情态动词或助动词could，would，should等时，可直接在其后面加not构成否定句。
例如：I could get you a concert ticket. → I could not / couldn't get you a concert ticket.
【技巧2】当句中含有系动词was，were 时，可直接在其后加not构成否定句。
例如： I was on the Internet when you called me. → I was not / wasn't on the Internet when you called me.
【技巧3】当句中谓语是除情态动词、助动词、系动词was, were以外的动词时，在该动词之前加did not / didn't，动词还原，构成否定句.
例如： The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs. 二变：陈述句变为一般疑问句
【技巧1】移动词语的位置。将was，were, could，would，should等移到句首。例如：
He could pack his things himself. → Could he pack his things himself?
【技巧2】添加助动词did。谓语是除情态动词、助动词、系动词was, were以外的动词时，在主语之前加did，动词还原例如： Mr Li looked very old. → Did Mr Li look very old?
