人教版七年级上册 unit 9 教案.doc

人教版七年级上册 unit 9 教案今天我们主要学习Unit 9中一个新的时态 一般过去时态（The Simple Past Tense）。复习一般现在时态的用法：第一、 经常性或习惯性的动作，常与表示频度的时间状语连用。时间状语： every, sometimes, at, on Sunday。例如： I leave home for school at 7 every morning. 每天早上我七点离开家。第二、 客观真理，客观存在，科学事实。例如： The earth moves around the sun. 地球绕太阳转动。第三、 现在时刻的状态、能力、性格、个性。例如： She is good at singing. 她擅长唱歌。（be good at） Ann writes good English but does not speak well. 安英语写得不错，讲的可不行。 1. 定义：一般过去时态表示在过去发生的事情，其时间状语一般是表示在过去，这一点是其典型的特征。和一般现在时态相对应，时间状语表示的时间不一样。2. 动词过去式的构成。在这里要注意有两种情况：规则动词VS不规则动词（1）规则动词的过去式的构成规则： 一般在动词原形末尾加-ed.比如：动词原形lookplaystartwantworkstay过去式lookedplayedstarted 以e结尾的动词，在末尾加-d.比如：动词原形livehopeuselikedecide(下决心)guide(指导)过去式livedhopedused 末尾只有一个辅音字母的重读闭音节词,先双写这个辅音字母，再加-ed比如：动词原形stopplanshoptrip(出差错)过去式stoppedplanned注意与Unit 5 所学习的表示现在进行的V-ing区别开来。stop _(v-ing) shop_(v-ing) plan_(v-ing) 以辅音字母加y结尾的动词，先变“y”为“i”，在加-ed. 比如：动词原形studycarryworrycry(哭泣)过去式studiedcarried动词的过去式和原形不一样，那么该如何去读每个单词呢。下面我们来学习规则动词-ed的读音规则：a:ed在清辅音后面读/t/;例如：cooked passed helped looked b: ed 在元音、浊辅音后面读 /d/ ；borrowed moved enjoyed c: ed 在 /t/ /d/ 音后面读 /id/ started wanted shouted needed 小结：清念/t/，元浊/d/，/t/d/ 后面是/id/。 （2） 不规则动词的过去式.下面例举了部分常用的不规则动词的过去式，这些不规则动词的过去式，最好能熟记在心。原形过去式原形过去式原形过去式am ，iswasdodideatatearewerecatchcaughttelltoldbeginbegancomecamewritewrotebreakbroketaketookseesawbringbroughtsaysaidgowentbuyboughtmakemaderunrancancouldsitsatputputsit_(v-ing) begin _(v-ing)不规则动词的过去式要花心思去记忆，避免和规则动词的构成规则混淆。3.一般过去时态的用法： （1）表示过去某个时间发生的动作或存在的状态。 A. He was here yesterday.昨天他在这儿。 B. I got up at six thirty yesterday morning.昨天早晨我六点半起床。 C.

A: 肯定句：主语+动词过去式+其他。eg: Tom bought a new book last week. B: 否定句：主语+did not ( didnt ) +动词原形+其他。eg: Tom didnt buy a new book last week. C: 一般疑问句：Did +主语+动词原形+其他？肯定回答是Yes, 主语+did. 否定回答是：No, 主语+didnt.
