案例：八年级（下）Unit 2 What should I do？{dy}课时Section A 1a-2c。

T：Everyone has some problems in their life. Now let’s listen. What problems do you they have?

我走到已经准备好磁带的教学录音机旁，按下电源键。我大吃一惊，录音机大声地播放着“最近比较烦，比较烦，比较烦，总觉得钞票{yt}比{yt}难赚，朋友常常有意无意调侃，我也许有天改名叫周转，……”（原来是有学生将录音机功能调到了收音状态，这首歌是收音机里播放的。）学生顿时一片大笑，有几个较调皮的学生还跟着录音机唱着歌词。于是，我就“因势利导”，“借题发挥”：

T：Is it a nice song?

Ss：Yes. / No. (有些学生说Yes, 有些说No.)

T：Listen carefully. What problems do they have in this song?

接着让学生听完这首中文歌曲。（大约用了2分钟时间）

T：What problems do they have?

接着叫了三位同学起来回答，包括刚才跟着录音机唱着的其中一名同学。

S1：They have no money.

S2：They are sad. And they don’t have enough money.

S3（就是刚才跟着唱的那位同学）：They are upset. It’s more and more difficult for Zhou Huajian to make money. And it’s more and more difficult for Li Zongsheng to write a good song. Xu Pinguan feels alone.

（顿时，一片掌声。）

T：Wonderful！Yeah. They have some problems. They are upset. Can you give them some advice? What should they do?

接着，我就顺势推进，继续围绕这首歌曲展开讨论。

S4：I think they shouldn’t be upset. They should face their life.

T：Yeah. We should face different difficulties in our life.

S3：Maybe they could ask their companies for help.

S5：Maybe Xu Pinguan should find some new friends in the new place.

S6：Maybe Zhou Huajian should get her daughter a good math tutor.

S7：I think Li Zongsheng and Zhou Huajian should talk with their wives.

S8：I think they should write and sing more nice songs，then they could make a lot of money.

T：Good ideas. I think if they hear our advice, their life will get better and better. But what problems do they have in the pictures. Listen and circle the problems you hear in activity 1a.

于是，我又将话题引回到了原先设计的课文内容教学上。

反思：这是一个很普通的课堂教学偶发事件，我没有因此乱了方阵，而是因势利导、借题发挥，并充分利用它作为自己的有效教学资源加以开发利用。意想不到的是，它却成了这节课的高潮部分，成了这节课的亮点、精彩之处。学xx言积极，而且观点鲜明、独到。同时，经过这个临时的活动设计，不断巩固了教学内容，而且还深化了教学内容，使学生在语言知识、功能、结构等方面都有了一定的提高，同时也渗透了德育。
