Summary （对这节课进行总结）
Step nine：Homework
1.准备听写这节课的重要词汇和短语
2.用英语写出本课所学中国地理知识的短文。
五、教学反思
1.要巧妙导入。
一堂好的课，不仅要求老师精心备课，熟悉了解教材，而且
要求老师优化课堂，增强趣味性，以吸引学生，激发学生的学习兴趣。
这就要靠老师导入合理。
2.教与学要有机结合。
既要有老师的教，更要有学生积极主动的参与，要将
学生被动变为主动，要体现学生的主体性和老师的指导性。
让学生学得开心快乐。
3.要把握好课堂时间。
不要完全按照备好了的课去上，必要时讲课内容可稍
微变动，以达到最好的课堂效果。
4.要公平对待好生与差生。
老师点学生回答问题时，不能只叫好的，差的也
要叫。
要根据问题的难易程度，难的叫好的，容易的叫差的。
这样差的就会想我也能回答出问题，能激发差生的学习兴趣，提高他们的自信心，也有利于整个班级成绩的提高。
5.通过这节课我深刻体会到了备课既要备教材，也要备学生的重要性。
