案例一利用构词法帮助学生记忆单词
学生学习了表示职业的单词teacher, worker, driver, farmer, cook 后,教师继续进行单词教学。
T: Different people do different jobs. What do you want to be?
S1: I want to be a teacher.
T: what do teacher do? Do you know?
S1: Teachers……
学生不知道该如何说,老师边做动作边提示:
Teachers teach. I’m a teacher. I’m teaching now. Do you know the meaning of the word “teach”? Guess.
S1: 教课。
教师出示单词卡片,带学生读。
T: Yes, teachers teach. Teachers like teaching. What about workers?
What do they do?
S2:Workers work.
T: Good, can you spell “work”?
S2: Yes, w-o-r-k.
T: What does it mean?
S3: 工作。
T: Excellent.
同法拓展:drive驾驶,farm务农。
教师出示一首儿歌,让学生边做动作边说儿歌:
I’m a teacher, teach, teach, teach,
I’m a worker, work, work, work,
I’m a farmer, farm, farm, farm,
I’m a driver, drive, drive, drive.
接着教师要求小组讨论:观察句中单词的拼写,能发现什么?
S4:”teacher”去掉er就是teach,worker去掉er就是work,farmer 去掉er就是farm,driver去掉er就是drive。
T:Yes, you are very clever.
幻灯片呈现以下内容:
英语中某些表示动作的词加上er,可以表示做这件事的人。
如:teach—教,teacher—教书的人(教师)。
T: Now, I want you to make a new rhyme.
I’m a ,sing,sing,sing.
I’m a ,write,write,write.
I’m a ,read,read,read.
学生很快完成了儿歌,教师带学生一起表演儿歌。
接着,教师出示了以下内容:
I’m a ,cook,cook,cook.
S5:I’m a cooker,cook,cook,cook.
T: Look,this is a cooker. You can’t be a cooker.
幻灯片出示了一只锅的图片,学生反应过来,想起了刚学的cook。
S5:I’m a cook,cook,cook,cook.
T: Yes, you’re a cook, cook,cook,cook.
幻灯片出示厨师图片,教师引导学生理解cook与cooker的意思,同时意识到不是所有动词加er都表示做此事的人。
