第三篇：过去进行时教案

Teaching Plan 1.Teaching content(教学内容): The Past Continuous Tense(过去进行时态)2.Analysis of teaching material(教材分析): 由于我是教的语法，按照教学大纲，结合语法体系，我这节课将要讲到的是过去进行时态。因为之前学生已经学习了一般现在时、现在进行时、一般过去时，所以这个时态对于学生来说并不是很难的。让学生在一个轻松快乐的环境中很好的掌握好此时态是我的目标。所以我针对教学内容，设计了一系列的活动，让整个教学内容很好的贯穿于一个个活动中。

3.Teaching objectives(教学目标):

a.Knowledge ojectives(知识目标)

要求学生掌握使用过去进行时

b.Ability objectives(能力目标)让学生做课堂的主人，培养他们掌握一些行之有效的学习方法，优化学习效果

c.Emotional objectives(情感目标)

1.让学生爱上英语课堂活动，鼓励他们在课堂上进行合作交流

2.设法使学生掌握使用英语进行交流，学习积极参与班级活动。通过大量练习来巩固所学时态

4.Teaching key points(教学重点)1.复习过去进行时的用法；

2.学习新的词汇和短语的用法

5.Teaching difficult points(教学难点)

1.让学生了解在怎样的情景下使用过去进行时；

2.创设情景设计话题，使语法项目在交际活动和完成任务中得到熟练掌握

6.Teaching methods(教学方法)

1.任务型教学法：

2.情景教学法 3.交际教学法 7.Teaching aids(教学用具)a computer, CAI, a recorder, the blakboard 8.Teaching procedures(教学过程)StepⅠ导入 1.呈现图片

1)T：What are you doing when I enter the classroom?

2)T:：Please look at the pictures on the screen and then tell me what they are doing?

【设计说明】

这些图片的设计目的在于吸引学生的注意力，让他们能立刻进入角色，投入到学习中来。在复习现在进行时用法的同时，慢慢导出今天的语法。

2．猜测性提问

Ｔ：What was I doing at 7 o’clock last night? Do you know? Guess.鼓励学生充分发挥相象力，大胆进行猜测。

如 S1：You were watching TV.S2：You were having supper.S3：You were talking to your family.在学生回答我问题的同时，将学生说的句子板书在黑板上：

You were watching TV.You were having supper.You were talking to your family.【设计说明】

因为之前已经复习过了现在进行时态，所以学生能比较容易的用正确形式复述过去进行时态的形式。通过这些问题，引导学生利用这一句型进行自由想象的猜测性提问。这种师生的双向提问加强了师生间的课堂互动，使师生关系更加和谐和融洽。同时师生间的信息差距更能激发学生积极主动地参与思考。

3.观察句子

让学生观察黑板上的句子，找出相似之处（was doing），然后介绍这就是今天要学习的新时态——过去进行时。StepⅡ 精讲规则

通过导入部分引导学生自己归纳过去进行时的构成。

因前段时间刚学习过现在进行时，且这两种师太有许多相似之处，于是通过复习现在进行时，与今天要学的过去进行时进行对比学习，引导学生自己推出过去进行时的肯定、否定和疑问形式。【设计说明】

毕竟是种新的语法，我觉得有必要帮助学生自己复习透彻现在进行时以后再推断出过去进行时，所以在黑板上逐步板书呈现了两种语法的比较，以利于层层深入，也让学生一目了然。StepⅢ 专项练习1.口头练习

练习was /were的用法, 对学生进行大范围的造句练习，采用了老师说出时间 “then”和主语,学生站起说出完整句子的形式。如, “I was working then.”是面向全体的练习。

然后用Lucy在上周不同时间干的事情，用二人小组练习，涵盖了第三人称，否定形式，一般疑问形式和回答。2.笔头练习

三道练习题由易到难，先是第一题写出动词的现在分词，然后是第二题对照明确的时间状语，用所给词的适当形式填空，最后是第三题在文章中根据所给单词的适当形式填空。【设计说明】

先说后写，层层练习过去进行时态，同时大范围的练习造句，让每个学生均有机会参与到教学活动中来，体会成功的喜悦。Step Ⅳ 综合运用

1.拓展延伸，询问查凶，口语交际，练习过去进行时：

在学生对过去进行时已经有了较为充分的理解之后，我特别设计了一个口语交际环节，当铃响时你正在干嘛?需要学生运用所学的过去进行时，设计好台词，而在充分的小组准备后，上台表演时，这样的设计，更能调动学生的参与兴趣，既要开动脑筋，精心准备，还要仔细聆听，细心观察，做出判断或改错。【设计说明】

这个环节，对学生用英语表述、分配任务、推断案情的要求极高。尤其是对用过去进行时提问，回答、推测，使学生把刚练习过的时态落实到实战—实际交际中来，这种设计应该是一种极为有效的反馈矫正手段。2.游戏： a.拍桌子

此游戏就是锻炼学生的听力和反应能力，我准备了十几个句子，要求学生注意这些句子的主谓一致是否正确，如果正确则很快的拍一下桌子，如果是错误的句子就不做任何动作，坐着不动拍错和拍得最慢的被淘汰起立。最后剩下的几名学生就为胜利者，获得加分的奖励。句子如下：

a.He was playing basketball yesterday afternoon.b.They was swimming in the lake.c.Your father was repairing the car.d.My mother and I were reading books.e.My friends was watching the match on TV.f.The children was leaning English.g.All of them was playing table tennis.h.My homeroom teacher was sitting in the office.i.I am looking at the picture.j.Neither Lily nor her parents were listening to the radio.b.你做我猜

准备10个卡片，每张卡片上写上“I was doing sth.”即每个卡片上有一个动作，比如打扫教室，骑自行车，做饭等等。让一个学生在前面来抽签然后做动作（不能出声），其他学生猜测，并且要问“Were you doing …?”如果正确，则做动作者要回答：“yes, I was doing …”;如果错误，则回答：“no, I was not doing …”回答正确的学生有加分以及进行下一个动作表演的奖励。卡片上的句子展示如下：

I was cycling.I was cleaning the classroom..I was talking to the teacher.I was cooking.I was swimming.I was listening to music.I was planting a tree.I was doing my homework.I was dancing.I was reading a newspaper.【设计说明】

为了活跃课堂气氛，设计出游戏环节，a游戏既训练了在规定时间内学生的反应速度，又锻炼学生的听的能力，激发了学生的竞争意识。通过b游戏一方面可以使学生们更熟练的运用过去进行时的三种形式，另一方面也可以激发学生学习和思考的兴趣，让课堂气氛在学生们有趣、逼真的动作表演中达到高潮。最后根据回答的情况，评出胜利者，给予适当的表扬和鼓励。

StepⅤ Summary 1． 补全对话

A：What ▁ you ▁ when I saw you yesterday?

B：I was ▁(listen)to music at that time.Then were you ▁(watch)TV at 7 o’clock last night?

A：No, I was ▁(write)a letter.2．与学生一起归纳过去进行时的用法

【设计说明】

让学生以对话和与老师一起归纳的方式巩固过去进行时的用法。9.Homework 用过去进行时态造十个句子，注意要用不同的主语和谓语

10.教学反思

教学成功之处是引导学生一步接一步从浅到深，按预想教学内容理解并能运用了过去进行时态。引入部分和环环相扣的游戏环节让学生在短时间里产生了学习的积极性和求知欲。整个课堂气氛轻松活跃，让学生更加大胆地展现自己；同时也在奖励制度下，学生之间也存在着激烈的竞争，课堂表演的部分达到了师生课堂的高潮部分。充分显示了“student-center”及以学生为中心的教学理念。

不足之处是可能没有顾及到班上极个别基础比较差的学生，对基础差的学生就比较看轻了一点，课堂节奏比较快，没有时间给予个别辅导。

11.资料链接

第四篇：过去进行时教案[最终版]

过去进行时教学设计 西林中学： 李秀珍

一、教材分析: 1.位置和内容: 外研版八年级下册第七模块第三课时。谈论如何使用过去进行时。如何使用过去进行时是本单元的重点内容。同时我创造了一些便于进行沟通交流的情境，让学生学会使用过去进行时。过去进行时是以前学生从未接触过的一个语法项目。这是一节前置语法课。学生对现在进行时已经比较熟悉，过去进行时的结构和用法与之较为相似。

2．教学重点:如何使用过去进行时。

3．教学难点:如何在由when, while引导的时间状语使用过去进行时。

二、教学目标：

1.知识目标：要求学生掌握使用过去进行时。

2.能力目标：让学生做课堂的主人，培养他们掌握一些行之有效的学习方法,优化学习效果。

3.情感目标：让学生爱上英语课堂活动,鼓励他们在课堂上进行合作交流。

4.学习策略目标：设法使学生掌握使用英语进行交流，学习积极参与班级活动.通过师友合作的学习模式来巩固所学时态。

三、教学方法：

1)和谐互助高效课堂教学模式： 2)小组合作

3)师友合作

四、学情分析: 学生七年级下册就学过现在进行时,并掌握如何使用现在进行时来描述日常活动,而且掌握了一些日常活动的短语，已经能够正确理解句子了，对各个时态的区分已经有了基本上的认识,有利于他们学习过去进行时.五：教学用具：PPT小黑板 教学步骤： ㈠ 温故而知新 ①向学生展示四张有关现在进行时的动画图片,问学生四个问题： 1,老师：Listen！What is happening？ 学生：It’s raining.2，老师：Look！What are they doing？ 学生：They are dancing.3，老师：What is the woman doing now？ 学生：She is lying on the grass.4，老师：What are the fish doing at the moment/ right now？ 学生：They are swimming.②让学生观察上面四幅画所涉及到的句子，师友、小组间合作讨论，归纳出： ⑴现在进行时的定义： ⑵现在进行时的基本结构： ⑶现在进行时的标志词： ⑷现在进行时的基本句型（陈诉句，一般疑问句，否定句）： ⑸V-ing的变化规则： 设计意图：通过生动带有 动画形式的图片，创设活泼轻松的课堂气氛，调动学生参与课堂的兴趣。让学生自行观察四个典型句子，通过师友、小组合作形式讨论归纳出现在进行时的用法，增强学生归纳，总结问题的能力，通过对旧知识的巩固复习，形成新能力。㈡导入新课 ①出示动画图片： 老师：What was the rabbit doing at 9 last night？ 自然而然导入“过去进行时”的课题。② 出示四个过去进行时的典型句子： 1，I was dancing at 8 last night.2，Were they having a party at that/this time last night？ 3，You were not playing the piano then.4，What were they doing from 7 to 10 yesterday afternoon？ 让学生观察上面四句子，师友、小组合作讨论出，归纳出： ⑴过去进行时的定义： ⑵过去进行时的基本结构： ⑶过去进行时的标志词： ⑷过去进行时的基本句型（陈诉句，一般疑问句，否定句）： ③讨论完成后，写到小黑板上，并展示。设计意图：让学生在对现在进行时归纳总结后，再推导出过去进行时的用法，让过去的知识能力得到迁移，提升，形成解决新问题的能力。此外，让学生自行推导，归纳出过去进行时的用法，而不是将知识的原委直接告诉学生，让学生自己思考，解决问题，激发学生的求知欲，增强学生课堂主人翁的地位，能培养，激发学生的创新能力。㈢ 当堂练习 造句接龙游戏： 教师在幻灯片上出示一个过去进行时的提示词，共有四个提示词，每个提示词让3个学生接龙造句： 学生A随意做一个动作，后问学生B：What was I doing at 8 last night ？ 学生B 根据学生A所做动作回答问题：You were …… 学生B随意做一个动作，后问学生C：What was I doing……？ 如此循环，按次序用四个标志词造句。设计意图：通过游戏的形式，让单调的语法课变得生动起来。通过口头的不断强化练习，加强学生对过去进行时用法的掌握。㈣ 巩固提高 ① 教师出示几个关于when/while引导的过去进行时的句子 让学生观察句子，总结归纳出两者的用法区别。② 出示when/while相关练习题。让学生先师友合作，共同完成。③中考链接：出示近几年过去进行时的中考题。让学生先师友合作，共同完成。设计意图：习题难度依次增加，检验学生对知识的运用能力，巩固学生新学知识，形成决绝问题的能力。

㈤ 归纳总结。① 师友之间互相讨论，归纳本节课所学知识。教师提问及对师友本课学到了什么知识。② 师友互评。设计意图：及时总结，能让学生对所学知识形成完成清晰的网络；师友互评，师友之间通过互相诚挚的评价，让师友双方能认识到自己的有点和不足，同时能增进师友之间的感情，有益于他们今后进行更好的合作学习。6

第五篇：过去进行时教案分析

[内容提要] 含6大部分：本单元教学目标、知识背景、重点难点分析、词汇讲解、时态等语法突破、语言点19个的讲解。资料贯穿整个单元，方便教师备课、学生学习、复习。

一.本单元教学内容：

Hello , boys and girls.How's everything going ? In this unit , we will learn to talk about past events and to tell a story.（一）语言目标（Language goals）

1.Talk about past events.谈论过去发生的事件。

2.Tell a story.讲述故事。

（二）语言结构（Structures）

1.过去进行时态： “was / were + doing”结构

4.bathroom（浴室）barber's（理发店）barber shop 理发店 shower（淋浴）police officer（警官）

5.another（另一个）jump down（跳下来）go up（向上去）

in front of（在……前面）

（五）重点、难点分析

1.过去进行时：表示在过去某一时间内正在进行的动作。

构成：was / were + 现在分词（其中was是am、is的过去式，were是are的过去式）

eg.1)I was doing my homework then.那时，我正在做作业。

2)He was cooking in the kitchen at 12 o'clock yesterday.昨天12点，他正在厨房烧饭。

用法：1）过去进行时表现过去某一时刻正在进行的动作。

eg.She was writing a letter when I came in.我进来时，她正在写封信。

2）过去进行时还表示过去某阶段正在进行的动作。

eg.They were waiting for you yesterday.他们昨天一直在等你。2.现在分词的构成

1）一般动词在词尾加-ing，读[iη]，如go→going。

2）以不发音字母e结尾的动词，先去掉e，再加-ing。

come→coming make→making write→writing 3）以重读闭音节结尾的动词，如果末尾以一个辅音字母结尾，应先双写这个字母，再加ing，x和w结尾的除外。

如get→getting swim→swimming show→showing

4）以字母y结尾的单词，直接加ing。

如carrying、playing、studying。

5）以字母ie结尾的动词，变ie为y，再加ing。

die→dying lie→lying

6）以元音字母加e结尾，或以e结尾，且e发音的动词，直接加-ing。

see→seeing be→being

3.使用进行时态的注意事项

1）一些动词，如see、hear、love、like、know、remember；understand、have等表示感情、知觉和状态的词，一般不用于进行时态。

2）在there和here引起的句子中，常用一般现在时代替现在进行时。

eg.Here comes the bus.There goes the bell.4.过去进行时和一般过去时的区别

1）过去进行时表示过去正在进行的动作，而一般过去时则表示一个完整的动作。如：

They were writing letters to their friends last night.昨晚他们在写信给他们的朋友。（没有说明信是否写完）

They wrote letters to their friends last night.他们昨晚写了信给他们的朋友。（表达了他们已写好的意思，整个写的过程已完成。）

2）当动作延续较长时间时或表示厌烦、赞美等感情色彩时，常用过去进行时表示。如：

He was thinking more of others than of himself.他考虑别人的比考虑自己的多。（表示说话者赞扬的口气）

The boy was always making trouble then.那时，他总是惹麻烦。（表示说话者厌烦的口气）

5.以when和while引导的时间状语从句

1）延续性动词和非延续性动词

延续性动词指动作可以延续一段时间，而不是瞬间结束。如：work、study、drink、eat等。

非延续性动词指动作极为短暂，瞬间结束。如：start、begin、hit、jump、knock等。

2）在本单元中，出现了以when和while引导的时间状语从句。

<1> when表示“当……的时候”。从句中既可用延续性动词，又可用非延续性动词，这些动词既可以表示动作，又可表示状态。从句中的动作既可和主句的动作同时发生，又可在主句的动作之前或之后发生。如：

Mary was having dinner when I saw her.The boy was still sleeping when his mother got home yesterday morning.<1> while表示“在……的时候”、“在……期间”。它强调主句的动作与从句的动作同时发生或主句的动作发生在从句的动作过程中。while从句中必须是表示动作或状态的延续性动词。如：

The weather was fine while we were in Beijing.She called while I was out.如果主句的动作在从句的动作过程中发生，从句常用进行时。如。

While we were swimming someone stole our clothes.Don't talk so loud while others are working.总结： <1> when可指时间点，又可指时间段，从句中可用延续性动词，也可用非延续性动词。

<2> while总是指一个时间段，从句中必须用延续性动词。

6.In this unit , we'll learn how to tell a story.Let's take section B 3a as an example.1）Listen to this story 听这个故事

Linda Jacobs loves her dog Davy.They went to New York City last Saturday.While Linda was buying a newspaper at the train station , the dog got out of his box and ran away.The station was crowded and Linda couldn't see Davy anywhere.When Linda shouted his name , some people looked at her but Davy didn't come.Then she called the police.While she was talking on the telephone , Davy met another dog outside the station.While the police were coming , Linda walked around the station and called Davy's name.She didn't think about looking outside the station.Finally , a little boy said to her , “Did you look outside ? I saw a big black dog when I came in.” When Linda finally saw Davy , he was jumping and running with another dog.There was a police officer next to them.The police officer said to Linda , “I think my dog found your dog.”

注意事项：

a.交代清楚故事发生的时间、地点及人物。

人物：Linda and her dog Davy;A police officer and his dog;A boy

地点：at the train station

时间：last Saturday

b.正确运用时态
