语法教学案例

《牛津初中英语》（译林版）8B Unit 2的语法教学内容是学习have been与have gone 以及延续性动词与短暂性动词的用法区别。我借助视频设计了以下教学任务。

Step 1：教师播放一段视频，内容是猪妈妈和小猪的一段对话，要求学生完成对话填空。

M um Pig：Hi, I am home. It has been a long and tiring day today.

L ittle Pig：W here have you gone, mom? （×）

M um Pig：?

L ittle Pig：I mean where have you been, mom? （√）

M um Pig：I have been to the flower market. I bought a pot of flower.

L ittle Pig：Mom, it has been a long day to me, too.

M um Pig：Tell me what you have done today.

L ittle Pig：I have finished all my homework.

M um Pig：Oh good boy. And?

L ittle Pig：I have cleaned all the rooms.

M um Pig：Pretty good. And?

L ittle Pig：I have eaten up all the food.

M um Pig：You must be very, very tired now, I should say. Oh, my God. What have you done! You h ave eaten this? You have ruined my precious flower.

L ittle Pig：But it has died for a couple of days.（×）

M um Pig：W hat did you say?

L ittle Pig：I mean it has been dead for a couple of days.（√）Furthermore, the flower you have mentioned is nothing but a cabbage!

（注：加黑部分为参考答案。）

Step 2：教师引导学生观察第一组打“√”、“×”的句子，比较have been/have gone 的用法区别，归纳第一个学习小贴士：have been表示某人去过某地，暗示人已经回来。have gone表示某人去了某地，暗示人还没回来。

教师引导学生观察第二组打“√”、“×”的句子，让学生小组讨论延续性动词与短暂性动词的用法区别，归纳第二个小贴士：die是短暂性动词，不能与a couple of days连用，要用相应的延续性动词be dead替换。类似的转换还有：leave–be away (from); join–be in/a member of; buy–have; borrow–keep; marry–be married; come/go/arrive–

be; begin/start–be on; finish/end–be over...

S tep 3：学生两人一组，在角色扮演中释放情感、积极体验，内化单元语法知识。

总之，语法的形式、意义和用法这三个维度在学习阶段应侧重于掌握其意义及灵活地运用语法。教师要充分利用各种教学资源，如优酷网上的语法视频教程、教材配套光盘、优质课件等创设适宜的情境，帮助学生在动态的情感体验和交际运用中达到形、义、用的有机结合。
