外研版高中英语必修三【教学设计】Module-4

Module 4 Sandstorms in Asia

本模块以Sandstorms

为话题，旨在让学生深入了解沙尘暴的起因和对我国乃至整个亚洲的危害，并通过以“沙尘暴”

和“环境保护”为话题的各种任务或活动，让学生掌握与沙尘暴和环境有关的词汇，了解沙尘暴方面的知识。培养学生用英语谈论沙尘暴及环保的语言技

根据上述教材的分析特征，满足《高中英语教学大纲》对英语阅读的要求以及素质教育中要培养学生综合素质能力的要求，结合学生的英语能力普遍薄弱这一学情，我为这一课确定了如下三项目标：

（1） 知识与能力：首先帮助学生复习掌握必要的生词及培养学生掌握良好的阅读习惯和阅读方法---跳读、略读和详读等。同时注意开发和培养学生的记忆能力，观察能力、想象、比较和分析能力，以及实践运用能力等。

（2） 过程与方法：以课文整体教学为中心，让学生通过group work 、pair work 等小组合作形式，运用不同的阅读方法，创设不同的情境，设置各种任务，使不同层次的学生都能够积极主动参与到课堂的各项活动中；充分发挥多媒体的作用，使课堂内容丰富，形象直观，从而为完成本节课的教学目标奠定基础。

(1) 掌握一些与沙尘暴和环保有关的词汇。

(2) 学习表达有关沙尘暴和环保的话题。

【教学难点】

EXERCISE

A sandstorm refers to a high amount of wind occurring in sandy areas, usually in deserts, where the wind speed is able to lift the top layer (层) of sand from the ground, and push it in every direction. The sand involved in the sandstorm can reach heights of about 3.05m—15.24m.

It is very dangerous to experience a sandstorm. Sand can get into the nose, eyes, mouth and lungs. If you happen to be caught in sandstorm, you must protect yourself by wearing masks, scarves(围巾) and so on.

If you’re driving when such a storm approaches, it’s advised that you pull off the road, since it’s difficult to continue driving. This is also important since vehicles can fail in during sandstorms and you could end up stuck on the road.

Most sandstorms occour in spring, and during the daytime. Many of the areas around the Persian Gulf and the Sahara Desert are associated with the most serious storms. Since it’s a natural phenomenon(现象), it can’t be entirely controlled. In areas that are natural desert regions, you can’t
