教学点评与反思：
设计思路：
任务型课程的设计要自始至终体现任务的要求与特点，尤其要确保任务的设计与完成是从简单重复逐步过渡到真实或接近真实。基于这一要求与特点，本课的四个任务先以谈论有关学校各项规章制度为话题，初步感受祈使句，以及如何表达规则；然后听（通过听那些能做、哪些不能做的事儿，体会情态动词can和can’t的用法）、认（通过认图标，说出规则，并把说出的规则写下来），最后根据常识或观察, 为图书馆、生化实验室、语音室、机房、健身房、游泳馆等公共场所制定规章制度或使用规则。这样，通过完成这一系列任务，既使学生学会了如何描述规章制度，又渗透了对学生的情感教育：通过对公共场所制定规章制度, 培养学生遵守公德、爱护公物的美德。同时，学生还可以学会发散思维，以扩展知识；口头及书面表达能力也可随之提高。
二、课后反思：
不足之处：图标展示得不够；还可通过图标渗透中外文化差异。
可取之处：全方位的训练了学生的听、说、读、写的能力。
