关于阅读课文的教学建议

  第50课课文“只有立足之地”通过介绍世界人口迅速增长的状况,说明控制人口增长的重要性和必然性。可以在让学生打开书前,问一些有关问题,如:

  The world's population is growing very fast. This is a big problem.

  Can anyone tell me why? 引导学生认识到世界人口的迅速增长会带来粮食缺少,就业困难和住房紧张等问题,并由此引出课文题目Standing room only。

  在解释课文题目时,可以让学生打开书看课文插图,或通过切身体会谈人口多的弊病与生活空间狭小的麻烦。可以引导学生通过阅读课文理解课文题目的含义,也可以先初步了解课文题目的意思预测课文中要谈到的内容。有意识地培养学生利用课文题目和课文插图预测课文内容的能力。在阅读课文前,可以给学生一个快速查阅(scanning)的任务,例如让他们在一分钟内,从课文中找出有关世界人口增长的一组数字。如:

  the number of babies born in one minute

  the number of babies born in one hour

  the world's population two thousand years ago

  the world's population in 1990

  阅读课文后,可以让学生分组讨论课文中提出的人口增长的问题,进一步认识到中国实行计划生育(Family planning)政策的必要性和深远意义。也可以做角色表演(Role play),其中一人是《中学生报》记者,另一人是人口问题专家,小记者和专家可根据课文内容就世界人口问题进行问答,然后互换角色。还可留作家庭作业进一步练习、巩固。
