4、惯是否容易改变，进而讨论有哪些不良习惯，最后思考可以怎样纠正这些不良习惯。这个过程能激活学生有关习惯主题的知识和经验，帮助他们形成阅读期待。从思维层次来看，活动1让学生调取生活经验，谈谈自己对不良习惯的认识，以及已知的改变习惯的做法，属于识记层次的思维活动。活动2是快速阅读环节， 引导学生关注文章各个段落的主旨大意。获取段落大意是本单元的主要阅读策略。了解各段落的大意有助于学生理解文章的主要内容，厘清文章的行文脉络，提高阅读效率。从思维层次来看，活动2需要学生分析段落的信息和观点，然后进行概括和总结，属于理解层次的思维活动。二、While-class学生活动：归纳段落大意。学生浏览文章，逐段提
5、炼主旨，检验并调整活动 2的答案和排序。教师活动： （1）核对答案前，允许学生先与同伴或小组讨论。核对答案时，可以请学生具体说出各段大意的匹配依据。例如在第一段，引导学生找出本段的关键句“To prevent harmful habits like these from dominating a teenagers life is essential”。教师可以简单分析，作者使用那么长的句子主语，目的就是要让这个句子引起读者注意。所以，这段的大意是 Why bad teenage habits should be changed。（2）在最后一段，引导学生发现关键句“However，there
