文档简介
初三英语第一部分:本节目标1. 复习过去进行时,在练习中灵活运用。2. 区别过去进行时和现在进行时。3. 掌握unit3的基础知识。第二部分:具体内容一、 温故知新:1. Who _ over there now? A. singing B. are sing C. is singing D. sing2. Its eight oclock. The students _ a PE class. A. not have B. arent having C. is having D. having3. Listen! The baby _ in the next room. A. crying B. cried C. is crying D. cries4. Look! The twins _ new sweaters. A. are wearing B. wearing C. are wear D. is wearing5. Dont talk here. Grandparents _. A. is sleeping B. are sleeping C. sleeping D. sleep二、 夯实基础现在进行时(一)、用法:1、表示说话时正在进行的动作。常和now连用,有时用一个动词如look(看)、listen(听)来表示now(现在)、Its eight oclock.这一时间概念。 Look!A train is coming.看!火车来了 Listen!He is playing the piano.听!他在弹钢琴。2、表示现阶段正在进行着的动作,但不一定是说话时正在进行。常和at present(目前)、this week(本周)、these days(这几天)等时间状语连用。 What lesson are you studying this week?你们本周学哪一课了?(二)、构成:Am/is/ are+ v-ing(三)、现在分词(V+ing)的构成:(1)一般情况下直接加ing. 如:reading, watching, cleaning.(2)以不发音的e结尾的词,去掉e再加ing. 如: take-taking, make-making(3)重读闭音节的情况,先双写一个辅音字母然后加ing. 如:put-putting.过去进行时(一)、用法:1.过去进行时表示过去某一段时间或某一时刻正在进行的动作。常与之连用的时间状语有,at that time/moment, (at) this time yesterday (last night/Sunday/week), at+点钟+yesterday (last night / Sunday),when sb. did sth等时间状语从句,如: What were you doing at 7p.m. yesterday? 昨天晚上七点你在干什么? I first met Mary three years ago. She was working at a radio shop at the time. 我第一次遇到玛丽是在三年前,当时她在一家无线电商店工作。 I was cooking when she knocked at the door. 她敲门时我正在做饭。(二)、过去进行时的构成:肯定形式:主语+was/were+V-ing否定形式:主语+was not (wasnt)/were not (werent)+V-ing疑问形式:Was/Were+主语+V-ing。(三)、when与while的区别:when 和 while 都有“当时候”的意思。二者引导的时间状语从句都可以表示正在进行某个动作,但是while更强调动作持续了一段时间,所以while引导的时间状语从句多用进行时态,when引导的时间状语从句多用一般过去时。1. when既可表示某一点时间,也可以表示某一段时间1.)用when引导的状语从句表示时间,说明一个动作发生的时候,另一个动作正在进行。(主句用过去进行时,从句用一般过去时)例如: I was reading a magazine(动作在进行) when my father came home(动作发生)last night. 2.)用when 引导的时间状语从句也可以表示某一个动作正在进行的时候,另一个动作突然发生。(when后面也可以跟动词的进行时,主句用一般过去时,从句用过去进行时。)例如: My friend called me(动作发生) when I was walking(动作在进行)in the park.2. while只能表示一段时间。在while引导的时间状语从句中,其谓语动词只能是延续性的,而且也只能与主句中的谓语动词同时发生或存在。 1.)用while引导的时间状语从句一般用过去进行时,表示正在进行某一个动作的时候发生了另一个动作,主句用一般过去时。例如: While he was reading ,the telephone rang. 2.)用while引导的时间状语从句还表示某个动作正在进行的同时,另一个动作也在进行之中。例如: While he was reading ,I was writing. While my mother was cooking, my father was watching TV.三、 能力提升(一)、 用动词的适当形式填空。1. While we _ (wait) for the bus, a girl _ (run) up to us.2. I _ (telephone) a friend when Bob _ (come) in.3.
