(2) 在以字母e结尾的动词后，只加-d。如：likeliked（喜欢）, provideprovided（提供）, hate hated（讨厌）, datedated（确定年代）。(3) 在以“辅音字母+y”结尾的动词后，则改y为i，再加ed。如：supplysupplied（提供）, flyflied（飞）, study studied（学习）. (4) 在以单短元音的重读闭音节结尾且，末尾只有一个辅音字母的动词后，双写最后一个辅音字母，再加-ed。如：planplanned（计划）, referreferred（涉及）, regretregretted（后悔）, banbanned（惩罚）. ps: offer侧重表示“愿意给予”，常用于offer sb. sth.或offer to do sth. 结构。provide指有远见，为应付意外、紧急情况等作好充分准备而“供给、提供”，可用于provide sb.（with sth.）或provide sth.（for sb.）结构。supply通常指定期“供应”，强调替代或补充所需物品，常用于supply sb. with sth.或supply sth. to sb.结构。四、部分不规则动词过去式归纳3词义现在（原形）过去式词义现在（原形）过去式是am, is (be)was有have, hashad是are (be)were听hearheard成为becomebecame受伤hurthurt开始beginbegan保持keepkept弯曲bendbent知道knowknew吹blowblew学习learnlearned, learnt买buybought允许，让letlet能cancould躺lielay捕捉catchcaught制造makemade选择choosechose可以maymight来comecame意味meanmeant切cutcut会见meetmet做do, doesdid必须mustmust画drawdrew放置putput饮drinkdrank读readread吃eatate骑、乘riderode感觉feelfelt响、鸣ringrang发现findfound跑runran飞flyflew说saysaid忘记forgetforgot看见seesaw得到getgot将shallshould给givegave唱歌singsang走gowent坐下sitsat成长,种植growgrew睡觉sleepslept五、一般过去时的否定句和疑问句1.带有was或were的句子否定句在be动词：was或were后加not。Eg1:I was ten years old then.否定句:I wasnt ten years old then.Eg2: Tom and his family were in America two years ago.否定句：Tom and his family werent in America two years ago.一般疑问句:参照陈述句变一般疑问句的规则：一提二改三照抄； 把was或were提前,其他照写。 Iyou; weyou; myyour; waswere。 剩下的内容照抄下来，加问号。Eg1:一般疑问句：Were you ten years then？肯定回答；Yes，I was. 否定回答；No, I wasnt.Eg2:一般疑问句：Were Tom and his family in America two years ago? 肯定回答：Yes, they were. 否定回答：No，they werent.特殊疑问句：针对不同部位提问，用不同的疑问词。Eg1: -How old were you then？回答：I was ten years old then. -Ten.
