　　discovering useful words and expressions

　　第一步：两人活动，一人说意思，另外一人猜单词，完成练习一。这一部分要注意的是不能单纯得为了练习单词而做题，要培养学生英语思维的能力（用英语解释英语单词）。

　　第二步：独立完成填空题，之后互相交换答案，解释自己为什么这么选择，在语篇中熟练掌握单词的应用。

　　第三步：速写比赛，课代表用英语念数字，进行比赛看谁写的数字准确率高，速度快，同样训练了学生用英语思维的能力。

　　one million, two-thirds, seventy-five percent, ninety percent, half a million, ten thousand .

　　第四步：完成练习 p63 第一题来巩固新单词。

　　discovering useful structures

　　第一步：学生重读课文，查找教材中带有 that,　which,　who,　whose 的句子。

　　第二步：教师针对每个句子提问，以帮助学生认识定语从句。例如：句子的主干是什么？主句和从句的关系是什么？等。

　　第三步：小组讨论，归纳这些句子之间的共同点，进而理解什么是定语从句，定语从句和先行词之间的关系，培养学生自主学习的能力。there are two kinds of this clause. one is the restrictive attributive clause, which modifies the noun; the other is the non- restrictive attributive clause, which gives extra information, and is written with commas. four relative pronouns the attributive clause use are who, whose, which and that.

　　第四步：看图说话完成句子，合并两个单句，试着用一个句子去修饰另一个句子。（例如 a boy is crying. he's got lost in the shop＝a boy who is lost in the shop is crying）以巩固学生对和定语从句中主句和从句之间的关系的理解。
