课堂导学方案
Step 1 复习
假如一位同学邀请其他几位同学到他家开party,对方不认识路，就询问路线编对话。
Step 2 情景导入
T：Hello, everyone. We all know that people sure change. Do you remember what you were like three years ago?
Now, think about my question and then I'll ask some students to talk about the changes of your appearance, hobbies, personalities and so on.
环节说明：通过问题引导学生针对各自的变化来引入新课，从而轻松导入新词used to。由于话题与学生自身息息相关，会更容易引起学生的学习兴趣。
