教学操作过程设计（重点写怎么教及学法指导，含课练，作业安排）
Step1. Revision
Review the grammar box. Ask students to use the structure on the book to describe the things.
Point out when we should use this kind of structure. And get the students to practice the sentences in pairs.
I have kept the book for three months.以上四种基本的现在时态，为了便于从总体上来比较、理解这四种现在时态，我们把这四种时态所在的时间轴放在一起，如下图：
综合上述四条时间轴，不难看出这四种时态的共同点：现在时态的基点时间都是“现在”（Now），它们的动作都与现在时间有关，这一点刚好与前面所提到过的“两时”中的“现在时”相吻合。
如：come/go—be, borrow/lend—keep等。e.g.
1)Tom has come here for three days.应改为:
Tom has been here for three days.
2)I have borrowed the book for three months.应改为：
The possible answers:
The boy was telephoning.
The girl is calling for help.
The alien is coming into the museum.
The UFO is landing.
The alien is going into the shop.

the floor and draw a picture on theboard.Ask the students outside the door to come in and sit down.Then ask the three students who were reading a book,sitting on the floor,and drawing a picture to sit in their chairs.Ask the first student who was doing an action,What were you doing when (Student A) walked in?Guide him or her to answer,I was reading a book when (Student A) walked in.Ask the class to repeat,He (She) was reading a book when (Student A) walked in.Repeat this with the second and third students who were doing actions.Draw a long horizontal line across the board.Write the words I was drawing a picture on the line.Then make a star in the middle of the line and write the words when (Student A) walked in below the star.Point to the straight line and say,This action continued for a long time.Then point to the star and say,This action happened quickly.Run your finger along the line as you say the words,I was drawing a picture.Then slap your hand on the board at the star as you say the words,when (Student A) walked in.Point out that the word when comes before a quick action that happens only once.The word while comes before an action that continues for some time.Ask students to say other sentences with when and while from this unit (or from their own lives).Step ⅧOptional ActivityDescribe an action that you did earlier in the day and that took only a moment to do and tell what time it happened.For example,I ate and listened to the news at 7:00 this morning.Then ask students to tell what they were doing at that time using the words when and while.Help the students make the first few students make sentences like these:I was sleeping when he/she listened to the news.or When he/she was listening to the radio,I was eating breakfast.Then describe similar actions at different times and ask students to make sentences using when and while.Step ⅨSummary and HomeworkThis class we’ve done listening,speaking and writing practice using the adverbial clauses with when and while.Today’s homework is to write reports related to UFOs.You can watch the video E.T. and write a short report about what happens in the movie.Or find a newspaper or magazine article about UFOs

八年级英语下册：Unit 3 What were you doing when the UFO arrived知识点复习(人教新目标版)
Unit 3 What were you doing when the UFO arrived?一. 教学内容：Unit 3 What were you doing when the UFO arrived?二. 语言目标：Talk about past events; Tell a story三. 目标语言：1. —What was he doing when the UFO arrived?—He was sleeping late when it arrived.2. When the UFO took off, the man was riding the bike.四. 重点词语精析：1. What were you doing when the UFO arrived?（1）这是一个含有时间状语从句的主从复合句，主句为what were you doing，从句是由连词when引导的时间状语从句，说明主句动作发生的时间。
ex: The students were talking when the teacher came in.I was watching TV when the bell rang.When I got home, my mother was cooking.（2）arrive 是不及物动词，如果表示到达某地，则用arrive in /at …，相当于get to…或reach。
需要注意的是，reach是及物动词，必须跟地点。
get to 跟地点名词，如果是地点副词，则省略介词。
如：get here/ home/there。
When did you ___________?When did you ___________ to school?They didn’t ___________ in China yesterday.We will ___________ there in two days.（A. arrive B. get C. reach）2. While the girl was shopping, the alien got out.while 在此处用作连词，意为“正当……时”，引导一个时间状语从句，通常用过去进行时，而主句通常用一般过去时，也可用过去进行时。

一、学情分析
我所教的班是农村中学的普通班，教学设备差，只有录音机和大小黑板。
教学所需图片，要布置学生事先画好。
学生学过一年半的英语，具备一定的英语听、说、读、写基础。
学习了约1500 个词汇、W/H 基础特殊问句和一般现在时、一般过去时、一般将来时、现在进行时五种时态及其句型，学习了国际音标。
这对本单元学习新词汇，学习过去进行时态，谈论过去发生的事情，都很有利。
二、教材分析
1、教学内容、教学活动分析及整合说明
本单元围绕“谈论过去发生的事情”这个话题，引导学生学习62 个生词、短语和谈论过去的事所用到的过去进行时及when/while 引导的时间状语从句。
教材通过图画情景和听说读写任务型活动，使学生学会有关词汇和句型，并通过话题短。

过去完成时
用时间轴来表示这一关系，更容易理解： 在时间轴上，我们只需借用数学中的平移方法，将
四种现在时态的箭头图标分别向左平移一个单位时间，
即由“现在”（ Now ）基点平移到 “过
去”（ Ago ）基点，其它的图标位置都不变，这样我们就可以得到以过去时间（
Ago ）为基点
时间的过去时态 .
Step5. 总结四种过去时态：
的时间也不同， 然而每一种过去时态和与之相对应的现在时态之间还是有一定的联系的：

实上，我们只需将现在时态中每一种时态的基点时间“现在”（

英语动词时态是一个语法范畴，它是用来体现、描述动作发生时间的动词形式。
英语动词中有两“时”（Tense）、两“体”(Aspect)、两“态”(Voice)之说；两“时”即是指现在时(Present Tense)和过去时(Past Tense)。据此我们可以将英语语法中的八种基本时态：一般现在时、现在进行时、一般（现在）将来时、现在完成时、一般过去时、过去进行时、过去将来时和过去完成时分为两大类：现在时态和过去时态，每一类各包括四种具体的时态。现在时态：一般现在时、现在进行时、一般将来时、现在完成时过去时态：一般过去时、过去进行时、过去将来时、过去完成时间轴（Time Axis）

Unit3. What were you doing when the UFO arrived? 1
Step3.在本单元开始之前，总结所学时态，并巧用时间数轴，理解英语时态
时间数轴法：借用学生所熟悉的数学数轴图，将各种时态所体现的时间点或时间段形象化地描在时间轴上，将时间轴分为三个区分点：过去（Past）、现在（Now）和将来（Future），而“Past”又可以细分为“Ago”（相对于“Now”的过去时间）和“Before”（相对于“Ago”的过去时间，即过去的过去）两个小的时间点，这样学生们就可以对各种不同的时间点或时间段有一个很形象、很直观的把握和了解。只要学生掌握了最基本的时态——一般现在时，就可以借用时间轴来推测、理解和掌握其他的几种时态，这其中涉及到平移问题、实线与虚线问题、直线与弧线问题。这是用一种很形象的数学图形方法帮助学生更好地比较、理解各种不同时态的内在联系和区别，从而使他们能更好地记忆、学习和运用时态，对于时态的基本构成和具体用法，让学生自己去认真记忆和实践。
