一、将较难的.问题分解为若干个小问题,使之简单化。比如,
Is it a good idea to built houses along the lines where two of the earth''s plates join together?
Is it a good idea to build houses on sand?
Can weak buildings stay up in an earthquake?
二、灵活运用多种提问方法
教师要活跃课堂气氛,驾驭学生思维,丰富课堂教学内容,就必须灵活运用多种提问方法,提问的方法有以下几种:
1、单个回答由个别学生单独回答某个问题。
2、小组讨论由小组成员集体讨论,最后由小组代表回答,其他成员补充。
3、全班讨论全班同学共同讨论同一问题,各抒己见,最终得出统一答案。
4、例如,在讲授高二英语上册的Lesson 34 EARTH、AIR与WATER三篇短文时,可以穿插以下的一些问题:
(1) is the area of desert growing every year?
(2) are the causes of air pollution?
(3) is the general cause of water pollution?
