一般过去时讲解及练习一、一般过去时的概念和用法一般过去时表示过去某个时间发生的动作或存在的状态，常和表示过去的时间状语连用。

一般过去时也表示过去经常或反复发生的动作。

Eg：-What did you do yesterday?-I met Lin Tao . （过去某个时间发生的动作）I was there a moment ago. （过去某个时间存在的状态）We often played together when we were children.(过去经常或反复发生的动作）注：表示过去经常发生的动作还可用used to 。

Eg：He used to smoke a lot, but he doesn’t now.他过去经常抽烟，但现在不抽了。

二、常用于一般过去时的时间状语yesterday, this morning，just, just now, ...ago（a moment ago，3 days ago，2 hours ago...), in the past，last night / year / week, once upon a time, the other day,以及时间状语从句中（常用引导词:before，after，when，until, as soon as 等）。

Eg：It was raining heavily when I left school.Mr. Green didn’t start cooking until his son was back from school last night.三、一般过去时对谓语动词的要求一般过去时用动词的过去式构成。

即一般过去时的谓语动词要用动词的过去式。

动词过去式的构成分规则变化和不规则变化两种形式，不规则变化通常需要逐个记忆，规则变化则遵循以下原则：(1)一般在动词后加-ed。

如：play—played（玩，打）, offer—offered（提供）, weigh—weighed（重）, destroy— destroyed（毁坏）, sign—signed（签名）.(2)在以字母e结尾的动词后，只加-d。

如：like—liked（喜欢）, provide—provided（提供）,hate — hated（讨厌）, date—dated（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：supply—supplied（提供）, fly—flied（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：plan—planned（计划）, refer—referred（涉及）,regret—regretted（后悔）, ban—banned（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 wasn’t ten years old then.Eg2: Tom and his family were in America two years ago.否定句：Tom and his family weren't 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；①把was或were提前,其他照写。

②I→you; we→you; my→your; was→were。

③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 wasn’t.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 weren’t.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.Eg2：Where were Tom and his family two years ago？回答：They were in America.2.谓语动词为实义动词的句子变否定句时在动词前加didn't，句子中的动词过去式变回原形。

变一般疑问句时在句首加Did，句子中的动词过去式变回原形。

Eg：Jim went home yesterday.否定句：Jim didn't go home yesterday.一般疑问句：Did Jim go home yesterday?肯定回答：Yes, he did. 否定回答: No, he didn’t.特殊疑问句：特殊疑问词+一般疑问句What did Jim do yesterday?随堂练习：一、单项选择：从下列各题后所给的四个选项中选择最佳答案填空。
