教学反思：本节课的重点是让学生认识和理解同位语从句，感受到高级表达的美并运用于写作中。从单句分析到成篇的短文修改，都围绕这个语法点。从课堂效果看来，学生的预习情况完成得不是很好，但是后面的任务还是能够较积极和主动去完成。这节课在对语法的解析方面是非常不系统不完善的，但是对于普通班的学生，基本了解和掌握还是比较到位的。对于具体的连接词的运用和高考题的完成，可以在下一个课时完成。在我看来，学习语法不在于学精学透，而是先要懂得为什么要学，懂得其实挺好学，然后才会有想学精学透的动力，才能更好地发挥学生的自主学习能力。这节课有很多不足，比如课堂用语不够规范和整节课不够连贯。公开课给了学生很大的表现机会的同时，给了老师充分的思考空间，只有精心准备一节课，才能让我们更有动力去完善自己，上好每一节课。
