Step 3完成教材Self Check的任务

1．让学生根据自己和父(母)亲日常活动频率的高低来完成1的表格。然后根据自己所填的内容来写5句话，写完后小组内互相交流纠错，并请几位学生读出自己写的句子。(5分钟)

2．认真阅读2中的对话，然后用本单元所学的知识来补全对话，完成后核对答案，学生大声地朗读对话。(5分钟)

环节说明：这一环节训练，让学生对本单元的频率副词有了更深刻的理解。

Step 4问题探究

()1.My sister always goes to work on time and she is ________ late.

A．sometimes B．usually

C．hardly ever D．ever

答案选择C，本题考查频率副词的运用，句首已经指明“我姐姐总是按时上班”，因此需选hardly ever 相承接，其他频率副词与always相矛盾。
