　　Say Yesterday we learnt about a traffic accident. In the accident, there was a man who got hurt. He was taken to hospital. But after a while, policemen came. Let’s see what happened after that.

　　Let the students imagine they are the children. Try to answer the policemen’s questions on page 123 Ex 1 in the workbook.

　　Get the students to act out the story.

　　要求学生四、五人就近一组。其中一位同学扮演警察，手持一个“记录本”；其他同学以“见证人”的身份向“警察”纷纷叙述事故发生的经过。四、五分钟以后，请两个大组到布置好的地点去表演。

　　教师也可考虑将学生分为若干个小组，分别扮演以下角色和准备以下内容：

　　l）李磊叙述事情经过；2）看门人叙述事情经过；3）赵老师叙述事情经过；4）骑摩托车人叙述事情经过。

　　以下提示供教师备课时参考：（可用投影形式展示）

　　角色1 (Li Lei) left school and saw a bag fall off a truck? shouted to the driver, but the driver did not hear; a man on a motorbike hit the bag and fell off; came up to help, asked the girl students to stop the traffic; helped to carry the man to the gate keeper's room, went to find Miss Zhao

　　角色2 (the gate keeper) heard the children shouting outside the school gate; went out to see what happened; saw two boy students carry a man; asked the people not to crowd around the man? asked Li Lei to find a teacher? moved the bag of rice away with Lin Tao

　　角色3 (the man on the motorbike) rode too fast that day; saw the bag, but too late; had an accident and fell off; hurt, could not move; two boys came to help; a teacher came with a medicine box; took me to a hospital

　　角色4（(Miss Zhao) reading a book at the library; Li Lei ran in and looked worried; told me about the accident; asked Li Lei to telephone the police; went to find a medicine box; quickly ran to the gatekeeper's room

　　Step 3 Presentation

　　Ask a student to come and perform an action at the front of the class. (e.g. sweeping the floor)

　　Ask What is he/she doing?

　　Then invite another student to come an perform a different activity (e.g. cleaning the blackboard) at the same time as the first student is sweeping the floor.

　　Say: The girl is sweeping the floor while the boy is cleaning the blackboard.

　　Explain while=during the time that something is happening.

　　Divide the class into two groups. Tell one group to mime writing. Tell the other group to mime reading. Say Group A is writing while Group B is reading.

　　Get the students to practise this sentence as they mime.

　　Step 4 Practice

　　Do the first sentence with the students, making sure they understand what to do.
