设计意图：通过多种形式的练习，及时复习巩固掌握本节课的重点语法句式——关系代词引导的定语从句，及时发现学生学习中存在的问题，教师进行适当的点拨解释，使学习印象加深，帮助他们拓宽语法知识，增长见识，使学生体会到英语的趣味和实用性。

Step 7. Evaluations and reflections

优点：本节课教学目标明确，条理清楚，板书设计合理，利用电影《Titanic》的故事及主题曲《My Heart Will Go On》引入学习话题，引导学生学习关系代词引导的定语从句，激发学习学习热情，歌曲和电影的引入使得枯燥的语法学习变得轻松有趣。学生在教师的引导下自主学习、合作、探究学习，能归纳限制性定语从句和非限制性定语从句的用法，并能熟练地进行运用，很好地完成了学习任务。

不足：

1、教师的课堂语言及表情动作应当更加丰富，这样才能更好地调动学生的学习热情。

2、最后一个环节用定语从句润色文章时间安排不足，应让更多的学生有展示语言学习成果的机会。

再教设计：最后润色文章留出更充裕的时间让更多学生展示范文，师生共同提出修改意见。
