教学内容
1．词汇：try to do
2．句型：It’s quite a nice picture.
3．语法：初步学习过去进行时态的用法。

课堂教学设计
Step 1 Leading-in
请三位同学到前面来，分别做出扫地、读书、写字等动作。教师依次提问：
T：What are you doing?
S1：I’m sweeping the floor.
S2：I’m reading a book.
S：I’m writing.
教师手指这三位同学，依次问大家：
T：What is he/she doing?
学生按照实际情景，依次答出：
S2: He is sweeping the floor. She is reading a book. He is writing.
教师要求全班将三个人的动作分别记清楚。
Step 2 Presentation
就刚才三位同学的动作，向全班提问：What was ×××doing when I came in?
重复两至三遍，板书这个句式，用彩色粉笔标出was，启发大家猜测句子的含义，并引导全班回答：
He was sweeping the floor.
She was reading a book.
He was writing.
板书上述三个答句，启发学生观察谓语部分的变化，并简要介绍一下过去进行时态所表示的含义。
Step 3 Ask and answer
借助课文插图或出示图片，让学生练习表达图中人物的活动。
T: It’s Monday. The students are drawing some pictures on the blackboard. Now let’s look at the picture. What are they doing?
让学生表达图中的各个学生正在进行的活动，并让他们表演出来。
A: What is Li Lei drawing?
B: He is drawing an elephant.
Han Mei is drawing a cat.
Step 4 Read and act
播放视频：Lesson93情景对话，问：What is Li Lei drawing?
或放对话录音。教师给出听前提问（Pre-reading questions）:
What is Li Lei doing?
放录音一遍，学生回答问题。
然后让学生就图中其他的学生进行对话练习并表演。
Step 5 Read and learn
告诉学生Now it’s Wednesday. 指着图片问：What did the students do on Monday?
出示对话：
A: What was Li Lei drawing when the teacher came in?
B: He was drawing an elephant.
试着让学生就其他几位同学进行替换练习。
然后引导学生从上面的句子中理解过去进行时的用法，并总结出其构成形式：was/were +v -ing
并引导学生对过去进行时和前面的现在进行时进行比较：
is/am/are +v-ing
was/were +v ?ing
Then let the students read the sentences given and answer questions in pairs.
或者播放视频：Lesson 93 Read and learn，然后让学生进行模仿练习。
Step 6 Practice
指导学生两人一组做课文第3部分练习。教师先与一位程度较好的学生表演以下对话：
T: What was Li Lei doing when the teacher came in?
S: He was drawing a picture.
T: What was he drawing?
S: He was drawing an elephant.
T: What was he drawing on?
S: He was drawing on the blackboard.
全班两人一组，就Meimei及the twins进行内容相似的问答练习，请几组同学表演。
