Where did Mr. Hu stand?
Who passed the stick to Yu Yan?
Did he catch up with Jim?
Which Class runner dropped the stick when he was passing it on to the last runner?
Who hurt his leg and stopped running?
4. Explain the language points.
1) get ready to do/be ready to do 准备做…… 例如：
强调行为 强调状态
I will get ready to leave for Shanghai.
I’m ready to help you.
get ready/be ready + for sth.
I'm ready( =I have got ready)for the exam.
Are you ready for the spelling? Yes, We are all ready.
2) But he quickly got up and went on running. 但他迅速爬起来继续赛跑。
go on doing sth. 意为:继续做某事。如：He went on talking about the film after the guest left. 客人走后，他继续谈论那场电影。
注意：这句话的意思是指客人在场时，他也在谈论电影。如果用下一种表达方法，则意思有改变：
He went on to talk about a film after the guest left. 客人走后，他(改变话题)开始谈论一场电影。
这个句子的形式是：to go on to do sth.
与go on doing sth. 意思相近的有go on with sth. , 例如：Please go on with your work. 请继续干你的工作。
3) He began to catch up with Jim. 他开始赶上吉姆了。
catch up with是追赶，赶上的意思。如：
1) You have to work hard in order to catch up with the others. 你得努力学习，赶上别人。
2) You walk on and I'll catch up with you later. 你接着走，我一会儿会赶上你的。
这一句也可写成：You walk on and I'll catch you up later.
在朗读这个短语时，注意将短语中的副词up读得稍重一些；而将介词with读得稍弱一
些。
4) pass…on to sb. 把……传给某人 on是副词，表示“继续，接着”，强调动作发生的连续性。pass的宾语是名词可位于on前或后，pass的宾语是代词必须位于on前。例如：
I’ll read the story after you, and then I'll pass it on to Lucy.
They both passed on their sticks/passed their sticks on at the same time.
After you read the note, please pass it on.
5. 教师板书以下短语，要求学生用动作表演：
1) stand at the starting line 2) Ready? Go! 3) Come on！4) pass the stick onto sb. 5) to be neck and neck 6) drop one's stick 7) fall, hurt one's leg, quickly get up and go on running
