教学过程
Step 1 ： Warm-up
（1）同桌二人运用句型：“What did you do last weekend？” “I + v.-ed.…”“Did you…？”“Yes，I did./No，I didn’t.”来询问上周末所做的事情。如：
S1: What did you do last weekend?
S2: I stayed at home and watched TV.
S1: Did you read a book?
S2: Yes，I did.
（2）播放本单元歌曲“Last weekend”，学生分小组比赛唱本单元歌曲。
Step 2：Presentation

T：What day is it today?
S：It，s Monday.
T：What do you usually do on Monday?
S：I usually have many classes.
T：What did you do last Monday?
S：I played football with my friends.
着重强调“last”表示“上一个”，引出last weekend/ night/Monday…
（2）T：What day is it today? S：It’s Monday.
T：What day was yesterday?（强调 yesterday）
S：Yesterday was …
T：What did you do yesterday?
S：I did …yesterday.
T：Yesterday was Sunday. What day was the day before yesterday?（引出“the day before yesterday”）
（3）开展连锁操练。
S1：（did）…yesterday.What did you do yesterday?
S2：I cleaned my room yesterday. What did you do yesterday?
S3：I washed my clothes. What did you do yesterday?
（4）T：You did so many things. What did Sarah do last weekend? 教师展示Sarah看书和看电影的单词图片，引导学生回答：She read a book and saw a film. T：What did John do last weekend?展示图片，引导学生回答：He had a cold and slept.
（5）展示动词原形及不规则变化形式的过去式，让学生注意区分并对比记忆。
read→read see→saw have→had sleep→slept do→did
（6）听“Let’s learn”部分的录音，跟着朗读，学习正确的语音语调。
Step 3：Consolidation and extension
（1）运用所学四个过去式动词以及动词短语说句子，如：S1：I read a book last weekend/night/Monday... What did you do …？
S2：I saw a film yesterday/last weekend… What did you do...?
（2）运用句型“I had a cold/saw a film/read a book/slept…Did you…？”学生之间相互问答，注意肯定回答和否定回答。
（3）完成“Look and talk”，主要运用句型 “What did …do ...?”“Did …？”“Yes，…did/No，...didn’t”，巩固句型，训练不同人称的回答。
（4）课堂小练习。

A. read B. readed
Did you B a film yesterday?
A. saw B. see
What B you do yesterday?
A. did B. do

教学反思
本部分主要解释不规则动词过去式的变化，要求学生能了解与过去式连用的过去时间，并继续巩固句型 “What did …do?” “Did …?” “Yes，… did./No，…didn’t.”了解人称变换之后的过去式问答，并能在日常交际中灵活转换人称，灵活对答。
