What were you doing when the UFO arrived教案2篇

What were you doing whenthe UFO arrived?教案一

一.教学目标

(一).知识方面:

1.培养学生能运用过去进行时来描述、谈论过去某个时间正在发生的事情或动作的意识和能力，能就过去某个时间正在发生的动作做出正确的描述。

2.培养学生的想象力和角色扮演的合作能力。

3.培养学生讲述过去发生的事情经过的能力。能正确运用一般过去时来讲述故事。

(二).技能方面:

1.本单元的语言目标是Talk about past events and tell a story（谈论过去的时间和讲述一个故事），围绕这一目标，要涉及句型：

What were you doing when the UFO arrived?

----I was sitting in the barber’s chair. The barber was cutting myhair.

因此必须学习standing、studying、cleaning、sleeping、cooking、making、eating、cutting、等表示地点的词，以便为上述句型提供语言材料。

2.学习过去进行时的有关知识。Was/were+现在分词，是该时态的表达式。

3.在学习过程中，要区分The boy was walking down the street when the UFO landed.和While the boy was walking downthe street, the UFO landed.这两种由when和while引导的状语从句的句型结构。注意它们的不同。

4.在本单元重要学习足够的关于一般过去时的知识，并能运用一般过去时这一时态来向别人讲述过去发生的事情经过。

(三).情感培养:

1. 让学生从本单元的学习中获得充分的想象力所带来的新鲜和快乐。

2. 让学生在相互谈论和角色扮演中学会合作、帮助，以获得共同进步。

3. 培养学生在谈论过去的事件和别人描述过程中获取成就感。

二.重点难点:

（1）重点：when和while引导的时间状语从句地掌握和运用：

The girl was shopping when the alien got out.

While the girl was shopping, the alien got out.

（2）难点：过去进行时和一般过去时在实际应用中的区别。

（3）疑点：在使用when和while引导的时间状语从句中，如何正确选用when 或while是学生疑惑点。

三.课时安排:

Section A:2课时.Section B:2课时.Self Check:1课时.Reading:1课时.

Exercise:1课时.合计:7课时.

四.教学策划:

本单元的语法要点是when和while引导的时间状语从句中和过去进行时态，涉及到过去事件的谈论和对过去事情的描述，因此在教学中采用动作演示、观看描述、现场讨论的方法和思路，充分利用教材中的卡通画，发挥学生的想象力，在对话交流讨论中，理解并运用该语法项目。

Section A 都是围绕本单元第一幅卡通画而展开的，是语言的输入阶段，呈现了本单元的主要语言动作和语法项目。1a、1b、和1c分别是看、听、说的任务型环节，均是1a中卡通画的内容。可先由Where were you when the UFO arrived?开始，然后再开始谈论What were you doing when the UFO arrived?引导学生在现在进行时的基础上运用过去进行时来回答：I wasshopping when the UFO arrived.

Section B是Section A语言功能和语法项目的再现、巩固和扩展.

Period1 and Period2(总第15——16课时)

Section A

一.教学目标:

1. 运用when和while引导的时间状语从句、一般过去时、过去进行时来谈论过去的事件，讲述故事。

2. 掌握过去进行时的用法，学会运用was/were+现在分词这一结构。

3. 立足本单元语言目标，培养学生的想象力和学习兴趣。

二.教学步骤:

1.情景导入

出示关于飞碟、外星人的图片(课前仿照教科书上的卡通画进行放大)问学生：What’s this? 诱导学生回答It’s a UFO/an alien, 由此激发学生的学习兴趣和热情。

2.课前热身

组织学生看课件并提出问题“What was theboy doing when the UFO landed?”引导学生回答He was riding the bike when the UFO landed。然后在谈论课件上别的人的情况。

组织学生做游戏。一个同学在门外站着，班上别的同学做动作，然后该同学进入教室坐下。这时教师提出问题What are you doing when Li Lei stood outside the classroom justnow?诱导学生回答：I wasreading a book when Li Lei stood outside the classroom just now或while I was reading a book, LiLei stood outside the classroom just now. 然后再换别的同学，重复上面的过程。

3.互动教学

Section A的语言目标是Talk about past events and tell a story.（谈论过去的事件和讲故事）1a的卡通画体现的就是“对过去的事件的谈论”，同时也是1b的听力、1c的结对练习的话题来源。学生应在对过去进行时的初步感知下来进行练习。2a、2b的听力材料一致，但目标任务不同，学生可逐步完成。3c的结对练习主要是呈现when/while引导的状语从句运用的不同，学生应在教师的指导下认真体会、练习。3a要求学生通过阅读，加深印象，完成3b的任务，讲述这个故事。本课第4部分让学生在开放的活动中去完成，练习过去进行时。

互动1

学生看教师展示的图片（飞碟、外星人，不同的房间），然后学生完成1a的配对。

师：What’s this?

生：It’s a UFO.

师：Where is the UFO?

生：It’s in front of myhouse.

设计意图----这样做的目的是导入新课，呈现新的词汇和本课内容。

互动2

师生共同看科幻片课件或师生游戏

师：What were you doing whenLi Lei stood outside?

生：I was reading a book whenLi Lei stood outside.

师：What was the man doingwhen the UFO arrived?

生：He was sleeping late whenit arrived.

设计意图-----这样做的目的是向学生呈现过去进行时（was/were+现在分词）句型结构。

互动3

师生共同讨论图片或课件内容，然后通过游戏练习when/while引导的状语从句。

师：What were you doing whenthe UFO landed?

生：I was riding a bike whenthe UFO landed. （教师诱导）

师：What happened while youare riding a bike?

生：While I was riding abike, the UFO landed.（教师诱导）

设计意图-----这样做的目的是向学生呈现when/while引导的状语从句在使用上的不同。

互动4

教师让学生看1a、2c的卡通画，1b提供的动作内容，然后让他们相互问答。

生A：Look at the man. What was hedoing when the UFO landed?

生B：He was sleeping late when itarrived.

设计意图-----这是让学生操作过去进行时，及when/while引导的时间状语从句，加深对这一时态的理解和运用。

互动5

学生进行第4部分的pair work, 相互问答，完成调查表。

生A：What were you doing at nineo’clock last night?

生B：I was sleeping/doing myhomework.

设计意图-----让学生在实际情境中理解运用过去进行时。

互动6

师生共同就3a的内容和图片讨论，完成图片的排序，然后完成3b的pairwork。

师：Look at this picture.What was the alien doing?

生：He was looking at thesouvenirs.

设计意图-----先就每幅图画的内容提问，有助于学生对每幅画和整个文章的阅读，也有利于学生根据图片内容讲述故事。

4. 达标检查

课后，完成一份某个同学昨天日程安排的调查报告，并根据这个调查报告，向全班同学讲述在某个时刻，他正在进行的动作。

5.教学反思:

①学习了过去进行时的结构和运用，was/were+现在分词。

②学习了when/while引导的时间状语从句When the UFO took off, the man was V-ing. While the girl wasV-ing, the UFO took off.

在学习Section A时，采用了图示说明法，动作演示法，直观呈现法等，在游戏活动中，通过交际，实现本单元所设计的语言目标。

三.知识延伸:

1.链接生活

链接一：如何向别人叙述两个动作同时正在进行？我们可以用while 来完成。

While I was doing my homework, my brother was watching TV.

链接二：下面句子中的while的词汇和用法有何不同。

1).We’re going away for a while.

2).Jane was dressed in brown while Mary was dressed in blue.

1)的while是名词“一会儿”的意思。2)的while 为转折连词，“然后”的意思。

2.实践探索

（1）课后，同学们想象“当自己遇见飞碟和外星人时”自己和自己的家人正在干某事，请根据自己的想象，向别人讲述这个故事。

（2）巩固练习:有步骤地完成学生练习册;同学讨论完成英语周报部分延伸拓展题目.

四.板书设计:

What were you doing whenthe UFO arrived?教案二

学生特点分析：

八年级学生有着极强的求知欲和表现欲。根据学生的心理特点，我在课堂上多以表扬为主，注重对学生英语学习兴趣的培养，鼓励他们大胆说、积极做！同时，培养学生养成良好的听、说、读、写等学习习惯，提高课堂教学效率。在今后的教学中，我将继续重视对学生英语学习兴趣的培养，采用多种手段帮助学生在记忆力强的时期多记单词，多学习语言规则，并尽可能多创造模仿的机会，提高学生的语音和语调，真正做到听说先行，读写跟上。帮助学生减轻学习负担，重新树立起学习英语的信心。
