Unit 2 I’ll help to clean up the city parks.
Grammar 4a-4c
教学反思：
本堂课是语法课，为了摆脱语法课的枯燥无味，本课从学生感兴趣的歌曲和手语导入，让学生充满新鲜感，对课堂产生期待。2.在语法教学环节，避免了传统的老师教，学生被动学。而是加入了微课和学案，让学生自己通过观看，总结出这节课的语法规律。这样让学生印象更加深刻，也更有积极性。3.在4a的练习中，增加了让学生自己分析“to do”的用法的环节，希望学生能学以致用。4.小组活动设计的比较基础，希望学生能把以前学过的短语能输出，同时注意“to do”的含义。课前发放彩色卡纸，让他们把小组讨论所得写下来并展示在黑板，增加他们的成就感。
遗憾：1.时间限制，无法把动词不定式其他很重要的用法一一让学生在课堂上探讨，只能留作家庭作业。课堂上练习还可以再多点，有些同学还是没有在课堂上完全掌握“to do”的不同用法。
2.学生们都很积极，但有个别同学害羞没有充分表现自己。
3.录课时网络不太好，有些地方有些卡壳。
