教学反思：

1.课堂导入环节站在学生角度，精心设计课前导入活动，以充分调动学生的兴趣及积极性，使学生更投入地参与到课堂中来。

2.课堂设计要合理，结构要流畅，教学设计按照由浅入深，循序渐进的原理，先让学生找出主旨思想及每段的主题句，然后再以完成任务的方式带领学生仔细分析每段的内容，让学生通过完成具体的任务来学习相关词汇知识并且在完成任务的过程中锻炼提升自己的阅读技巧及阅读能力，同时积累学习经验并享受成功的喜悦。

3.在任务教学法中，教师给出的任务要目的明确，并且在完成任务的过程中对学生多进行鼓励，以激发学生潜能，调动学生积极性。教师不仅是知识的传授者，还成为学习的促进者、指导者、组织者、帮助者、参与者和合作者，除了传授学生必要的语言知识外，还必须重视学生的个性和兴趣。在课堂中，教师通过多媒体技术为学生创设各种语言学习环境，提供丰富的教学资源，可以拓宽学生的学习渠道和学习方式。

4.本节课所存在的不足有：课堂容量较大，对时间的把握上不够准确，导致最后讨论环节时间紧凑，节奏较快，给学生讨论，发挥其主体地位的时间不够多，此环节没有达到预期的设计效果。在以后的教学过程中，应更加注意对时间的动态把握，以期达到预期的教学效果。
