说课

本节课导入部分用一个游戏来开始课堂教学，因为已经进行到第三课时，学生对一般现在时和一般过去时比较熟悉，所以把两个时态混在一起让学生做游戏，既调节了课堂气氛又帮助学生复习了两个时态。接下来通过趣味造句，让学生完成由词到句的提升。学生必须根据人物、时间和动作来迅速造句，这个游戏既考验了学生的快速反应以及对语法知识的掌握，同时用班级学生或者老师的名字来造句又增加了游戏的趣味性。完成Story time复习后，接下来呈现了几张今昔对比的照片，让学生尝试用简单的语篇进行阐述，完成了由句子到小语篇的提升。在文化知识拓展环节，不仅仅局限于课本上的文化背景知识介绍，同时也介绍了中国古代的四大发明，培养学生的民族自豪感。
