单词教学

通过freetalk 引出单词的教学:
T: I go to school by bus.
I know Wanglin goes to school by bus. （出示bus的图片）
Zhangfang goes to school by bus, too.
Lihong goes to school by car.
How do you go to school?
S: 有的学生会明白老师的意思，个别学生就能回答出：
I go to school by bus. I go to school by car.
当学生说出bus时，就举起bus的图片。教师重复 by bus
因为现在乘私家车上学的学生很多，学生很容易说出car这个单词，那么就借此机会拓展词汇，把car也给教了。教师重复 by car
教师这时找一个步行来上学的孩子问：How do you go to school?
如果这个孩子能说出： I walk to school. 就大力的表扬。
如果不能说出，教师就说： You walk to school.
(出示图片：walk)
T: walk to school 是一种非常健康、低碳的生活方式。
Who walks to school?
S: 走路上学的孩子就会踊跃来说：I walk to school.
现在骑自行车上学的孩子基本没有，所以就设计一个游戏：
看课件： How does he go to school?
学生会说：by bus, by car, walks to school
如果有学生猜出：by bike 就大力的表扬，并让该生领读词语。
