過去進(jìn)行時(shí) 教學(xué)案
目標(biāo)分解:1、理解過去進(jìn)行時(shí)的概念。
2、掌握過去進(jìn)行時(shí)的構(gòu)成(肯定、否定和疑問)。
3、識(shí)記過去進(jìn)行時(shí)的用法。
4、實(shí)例操練,學(xué)會(huì)做題。
教學(xué)重點(diǎn):教會(huì)學(xué)生掌握過去進(jìn)行時(shí)的概念、用法、構(gòu)成。
教學(xué)難點(diǎn):過去進(jìn)行時(shí)的構(gòu)成以及用法。
學(xué)情剖析:大部分學(xué)生做題時(shí)經(jīng)常遺漏be動(dòng)詞,而且對(duì)不同人稱be動(dòng)詞過去式的選用沒有掌握透徹。
方法選擇:課堂提問、小組討論
活動(dòng)(情景)設(shè)計(jì):以生活實(shí)際為例。
教具(實(shí)驗(yàn))準(zhǔn)備:舉例造句、句型替換、PPT
2、教學(xué)
教學(xué)過程:
教師:
一、 復(fù)習(xí)
在進(jìn)入新課之前先回顧一下上節(jié)課所學(xué)內(nèi)容—現(xiàn)在進(jìn)行時(shí)。包括現(xiàn)在進(jìn)行時(shí)的構(gòu)成,用法和現(xiàn)在分詞的規(guī)則變化。(教師引導(dǎo)學(xué)生統(tǒng)一復(fù)習(xí))
二、導(dǎo)入
以學(xué)生的狀態(tài)引出這節(jié)課的話題。以某某同學(xué)上課前正在做什么,然后讓學(xué)生翻譯句子,教師把句子呈現(xiàn)在黑板上。
同學(xué)們,我們仔細(xì)觀察一下黑板上的句子。都是表示學(xué)生上課前正在做某事,那么我們稱之為……?那么什么是過去進(jìn)行時(shí)?通過這些句子我們來解釋一下。
三、新課

識(shí)記表示過去的時(shí)間狀語:then,

2. 過去進(jìn)行時(shí)的構(gòu)成
同學(xué)們,那么過去進(jìn)行時(shí)的構(gòu)成是怎樣的呢?
(學(xué)生根據(jù)現(xiàn)在進(jìn)行時(shí)構(gòu)成及例句推測(cè)過去進(jìn)行時(shí)的結(jié)構(gòu),順便復(fù)習(xí)現(xiàn)在進(jìn)行時(shí)的結(jié)構(gòu))
例:
肯:She was listening to music then.
她那時(shí)正在聽音樂。
否:She was not listening to music then.
她那時(shí)沒在聽音樂。
疑:Was she listening to music then?
她那時(shí)在聽音樂嗎?
Yes, she was. / No, she was not.
是的
6、,她在聽。/不,她不在聽。
構(gòu)成: 主語 + be(was/were) + 動(dòng)詞的現(xiàn)在分詞
肯定形式:主語 + be(was/were) + 動(dòng)詞的現(xiàn)在分詞
否定形式:主語+ be(was/were)+ not +動(dòng)詞的現(xiàn)在分詞
疑問形式:(Was/Were) + 主語 + 動(dòng)詞的現(xiàn)在分詞
肯定回答: Yes, 主語 + was/were.
否定回答: No, 主語 +was/were+ not.
注意:(I, She, He, It, 名詞單數(shù))+ was
(You, We, They, 名詞復(fù)數(shù))+ were
3. 過去進(jìn)行時(shí)的用法
(1)
7、表示過去某一時(shí)刻或過去一段時(shí)間內(nèi)正在進(jìn)行的動(dòng)作。
---- what were you doing at that time?
你在做什么?
---- I was eating.
我正在吃。
He was having a haircut when his mother was out.
當(dāng)他媽媽離開時(shí),他正在剪頭發(fā)。
(2) 常和always等頻率副詞連用,表過去頻繁發(fā)生的習(xí)慣性動(dòng)作,帶有一定感情色彩。
She was always crying. 她總是在哭。
(3) 在以when與while引導(dǎo)的時(shí)間狀語從句中。
例:
① She was pla
8、ying games when her father went to
cook this time yesterday.
② His father came back when Jagger was driving
the car.
③ Olivia was looking at me while we were taking a photo.
1)主句動(dòng)作先于從句動(dòng)作,
主句:過去進(jìn)行時(shí);
從句:一般過去時(shí)。
2) 從句動(dòng)作先于主句動(dòng)作,
主句:一般過去時(shí);
從句:過去進(jìn)行時(shí)。
3)主從句動(dòng)作無先后關(guān)系
9、,
同時(shí)使用過去進(jìn)行時(shí),從句一般由while引導(dǎo)。
四、習(xí)題演練
1. 真題
(1). (2014湖南) Little Tom ______ computer games when his mother got home.
A. is playing B. plays???? C. was playing
答案:C
解析:本題考查過去進(jìn)行是的用法。由句意得知“小湯姆正在玩電腦游戲當(dāng)他媽媽回家的時(shí)候。
(2).(2014甘肅) She _____ to an Engli
10、sh program while her parents ______ TV.??
A. was listening; is watching??
B. listened; were watching?? ??
C. was listening; watched? ??
D. was listening; were watching??
答案:D
解析:句意-當(dāng)她的父母在看電視的時(shí)候,她正在聽英語節(jié)目。主句聽電視節(jié)目與從句看電視同時(shí)進(jìn)行,因此,主從句都用過去進(jìn)行時(shí)。
2. 用正確的形式來填空
(1)?What _____ you _________ (w
