教学反思
一、不足之处：
1．本节英语课上我的讲解基本上还拘泥于教材的信息，而开放型的、能激发学生想象力与创造力和发散学生思维的课堂比例还较小。
2．学生英语听，说的能力相对较弱，授课采用较深的全英教学，同学们还不能适应。
3.学生虽然比较活跃，上课气氛积极，但个体与个体差别比较大。重难点句子分析讲得太深，没有照顾到整体。
二、收获和优点：
1．学生在本堂课中得到了较为充分的阅读速读方法指导和口头作文训练，而且面比较广。
2.能够根据学情，调整教材的授课顺序，并根据课堂读写主题进行了部分删减(1c)。
3. 基础知识的总结精炼，讲练结合。讲解突出重点，抓住关键，杜绝了那种不加选取的重复练习，有针对性。
