事。一来，纯粹的语法课比较枯燥乏味；二来，本节课主要学习句型Whatmakes…dirty/messy?Whatcanwedotokeep…?以及它们的答句，内容较简单。其中的教学重难点是短语make+名词（宾语）+形容词（补语），教师通过呈现魔法棒的魔力，不断在故事中呈现这个短语，让学生在阅读过程中将故事中出现的这类短语全部找出来，同时让学生体会和总结规律，并在此基础上引导学生跟着故事情节，逐步说出魔法口令make+名词+形容词。随着故事情节的发展，通过“让我们保持公园的美丽”，提出Whatcanwedotokeeptheparkbeautiful?的话题，让学生操练句型Wecan…/Wecan’t…由于该句型较为简单，所以在故事中一带而过。进而将学生的视角拉到人们对公园环境的破坏，让学生来读Bobby和Tina的倡议书，并在理解的基础上，自己动笔来写一些倡议书，通过这个练习把这节课的两个句型结合在一起进行复习巩固。在本课的结尾处，教师播放了一组美丽的城市风景图，通过这个环节，联系生活实际，让学生感受我们城市里美好的风光，使他们产生“环境卫生，从我做起”的想法，让他们更加珍惜和热爱我们的城市，产生保护环境的意识。本节课的几个主要关注点：1.关注学生对语法知识的整体认识和具体运用。2.关注学生的合作性学习。3.关注学生的阅读习惯，培养他们的阅读兴趣。4.关注学生的情感发展，增强他们的环保意识。6
