1．直接加ed：work—— worked look——looked play——played, 2．以e结尾的单词，直接加d：live ——lived hope——hoped use——used,
3 以辅音字母+y结尾的，变y为i加ed：study—— studied carry——carried worry——worried,
4以元音字母+y结尾的，直接加ed：enjoy ——enjoyed play——played
5 以重读闭音节结尾的，双写最后的辅音字母+ed：stop—— stopped plan——planned
不规则变化：is/am-was Are-were Begin-began blow –blew bring -brought 基本结构
主语+动词过去式+其他
否定形式①was/were+not；②在行为动词前加didn't，同时还原行为动词
一般疑问句 ①Did+主语+do+其他？ ②Was\\Were+sb.+ do sth 例句She often came to help us in those days.
I didn't know you were so busy. 口诀
一般过去时并不难，过去动作、状态记心间。 动词要用过去式，时间状语句末站。
否定句很简单，didn't 站在动原前，其它部分不要变。
一般疑问句也好变，did放在句子前，主语、动原、其它部分依次站。 特殊疑问句也简单，疑问词加一般疑问句记心间。 最后一条请注意，动词过去式要牢记！
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：
6
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? 三变：陈述句变为特殊疑问句
【技巧1】确定疑问词：人who / whom，物what，地点where，时间when / what time，原因why，频率how often，长度how long，距离how far等等。例如：
They gave the concert last night. → When did they give the concert?
【技巧2】辨认结构形式：疑问词+情态动词/助动词/ was / were / did +主语+...? 例如： The accident happened near the station. → Where did the accident happen
一些不规则变化：
do>did see>saw make>made take>took eat>ate
read>read put>put get>got hear>heard feel>felt等等
