Some of you share your passage with usModel EssayWith nothing to do on the weekend, I decided to have a walk to the park, where I saw a beautiful lake surrounded by many flowers and tall trees. There were several children playing beside the lake, talking and laughing. Breathing the fresh air, I became aware that it’s the most fantastic thing I’d ever done. Suddenly, I heard someone calling for help. I ran over and found an old man sitting on the ground, with a painful look on his face. I learned that he fell down and got his leg broken. A young man dialed 120. With the help of two other girls, we sent the old man to hospital. Luckily, the old man was timely saved.

______________________________________________________________.Bye Bye！课后反思：
本课的教学围绕教学目标展开，基本完成了教学任务，学生在课堂活动中表现积极活跃，从个体活动到小组活动，再到集体活动，学生都能够积极参与，个体活动与集体参与都有所体现，使学生在有限的时间内较好地复习巩固了with复合结构、分词作定语和状语以及一些句式的用法，把握到位，这点比较满意。但是美中不足之处是对讨论活动的监控和测评方面经验欠缺较多，还有提升的空间；再者，对于连句成篇这部分没能留出足够的时间来处理，下步要进一步打磨课堂有效环节，争取更高效的完成教学任务。
