该环节是整个“测试”的第二个部分，是听后的第一个活动，通过 “再听1a”，教会学生抓关键词和重点短语的方式，灵活运用知识点，提高学生重组语言的能力。
建议：教师可根据实际情况设计1c为读后环节。
2是通过创设新的语境，巩固学生所学知识点，为后面的语言输出打好基础。
学习语法知识，也是为正确的语言输出，提升口语表达能力和书面表达能力做好铺垫，让学生会用英语做事情。
本课重点训练学生的听、说技能，实现了“ding fr learning”and“learning fr using”的教学理念。
在参与测试（申请加入志愿者俱乐部）前，教师可以通过学生的课堂表现，采用不同的方法（如：积分制；小组排位赛等）对全体学生进行考核，可以有部分学生不能通过测试，教师应该鼓励这部分学生，不要气馁，为实现目标继续努力。
