第一课时 Warming Up 第一步：教师可以采用以下的不同方式引出本单元的话题； 方案一: 可以直接利用课本热身部分提供的问题来引出话题。这一方案开门见山,不仅能很快切入本单元的主题,而且问题指向明确,学生比较容易展开话题。 方案二： 可以利用其它更为生动、灵活的方式如：在黑板上写下几种“朋友”这个词在不同语言里的表达，让学生猜这些词的意思以激发学生的学习兴趣（教师最好能知道这些不同表达的书写和读音，还可以让学生在课堂上试写和试读）；也可以播放一首以友情为主题的歌曲（无印良品：《朋友》；老狼：《睡在我上铺的兄弟》）或一段描述友谊的电影片段（韩国电影《朋友》导演：郭京泽主演：X东健），然后让学生就所播放素材的主题展开讨论，进入本单元话题；教师还可以引用一些国、内外谈论朋友的名人名言（见背景资料）来展开话题。 方案三：

可以事先让学生准备一X好朋友的照片，然后在课堂上让学生展示自己的朋友的照片并描述其主要特点。也可以让学生介绍自己新学期在新的班级里交到的朋友（此方案适合程度较好的班级）。 开展活动时可以全班一起进行，也可以分小组进行，但要提醒学生用英语进行表达。教师可以事先做一个 brain-storm，在黑板上列出一些描述人物的常用词汇和句型以帮助学生顺利完成接下来的活动，如： Personality：kind generous humorous Appearance：handsome pretty good-looking tall Hobby： sports reading traveling In my opinion / I think / As to me, he (she) is a ... person. He(She) always wears .... He(She) looks like.... We always do ... together. 第二步：学生完成课本热身部分的问卷调查。在一些学生程度较好的班级，教师还可利用网络或其它资源对原有的问卷进行一定的补充，丰富问卷内容（见背景资料），让学生计算得分并根据教师公布的各分数段所对应的性格类型得出自己的调查结果；（在调查过程中，教师可以对问卷内容中的部分新单词和词组作简单的解释以帮助学生顺利完成问卷。建议教师有针对性地保留对部分生词和词组的解释以锻炼学生的阅读理解能力） 第三步：小组活动，学生分成若干小组，讨论朋友之间建立友谊的基础，
