28、找出，要引导学生学会用自己的语言总结和归纳答案，允许有不同的表达方式。以1c的第一题为例（What caused Mrs. Zhous problem?）简单的回答就是pollution。如果要答案具体化，就必须先引导学生找出周夫人的问题，再找出原因，最后用自己的话归纳出答案（The chemical factories produce terrible gas, make too much noise and pour waste water into rivers）。学生能够正确提出问题，也是能力的体现。教师需要引导学生，一步一步朝着正确答案去思考，可以运用课文中的文本语言，也可以拓展例句

29、提供新的语境，还可以根据已学知识理解新知识（以短语“get a pain in”为例， pain 是本课新单词， 要理解短语的意思和掌握短语的用法就会比较难， 因此，教师可以通过“I have a sore throat”帮助学生理解意思。 用举例“I get a pain in my leg”同时捂住左腿，帮助学生观察该短语的用法）。课文朗读是培养学生的语感，训练语音语调的方法之一。为了让学生目标性更强，更加严格的要求自己正确发音，学会合作，教师采用（以六人组为例）组内三人扮演一个角色，进行对话；并采用一些竞争机制，激发学生的斗志和参与课堂活动的热情，维护小组的集体荣誉感。在角色扮演前，教师

30、选择率先做好准备的小组，让他们选择任一小组进行挑战，胜利者将得到老师的礼物（或者积分），落后组再选一组，循环挑战；也可以另外选择两组进行两两PK。6Summarizing and assigning homework (5 mins)Class activity Step 1: Let the Ss go over what they have learned this period.
