A new study warns that about thirty percent of the world’s people may not have enough drinking water by the year 2025.

The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflicts. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning.

The study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. As third way is to use less water for agriculture.

The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.

How to Solve Air Pollution

Too many cars have caused a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. One possible solution is to design and develop clean cars and clean fuels. In Shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as petrol. Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not buy private cars. Thus, the total number of cars in big cities will reduce greatly. On the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.

教学设计说明

教学材料

本堂为听说课，听说素材在高中英语口语测试题型的基础上从《高中英语听力强化升级训练》及网上截取。第一篇听力为世界水短缺的一篇报告，第二篇听力则为一名环境保护专家对空气污染提出的一系列控制举措。整堂课由5个listening task和3个oral task组成，围绕环境保护这一话题，综合训练学生的英语听说能力。

学情分析

本堂课的授课对象是高二（3）班学生，由40名学生组成。班级整体语言能力处于年级平均，班中个别同学英语语言素养好，部分学生听说的能力较弱。班中大部分同学对于环境保护这一话题比较熟悉，有话可说，但缺乏听中心句获取大意和记笔记的能力。

教法分析

听说课设计应借助各种教学活动使学生听说技能平衡发展。听是吸收和理解信息，说则是表达和传递信息，听与说的能力互相联系、紧密结合、共同促进、不可分离。听说课中还应带入真实情境，让学生在情境中接收新信息并操练，从而提高学生学英语、说英语、用英语的氛围和兴趣。

设计思路

这节课旨在指导学生通过听中心句获取大意和记笔记完整具体信息的能力以及利用课堂总结内容和情景带入熟悉巩固关于环境问题的实用词和句型。

听说指导环环相扣，听听说说相互穿插。

Listening task 1：通过抛出问题导入话题让学生进行听前预测，激发学生兴趣。两遍听力要求学生抓住中心句了解大意，并为下面二听获取细节信息做准备。

Listening task 2：通过记笔记来获取细节信息，验证自己一听中的笔记是否有效到位，并为下面第一个口头表达活动做准备。

Oral practice 1：根据之前所听内容，结合自己的生活经历，表达自己对环境保护的想法并提出一些可行的举措，并由此引入listening task 3。

Listening task 3：巩固强化学生抓住听力中的关键句来获取大意的能力，并进行有效笔记，为最后的口头输出做准备。

Listening task 4：巩固学生通过抓住文章开头中心句获取文章大意的能力，并引出listening task 5。

Oral practice 2：根据上面的听力内容，引发小组讨论，提出防治由车辆导致的空气污染的措施，为下一个听力任务和最后的口头采访做准备。

Listening task 5：强化学生边听边抓住中心句，并进行简短有效笔记的能力，听第一遍找到中心句了解大意，听第二遍确认中心句和细节问题，所得出的答案为下面oral practice 做准备。

Oral practice 3：给同学提供一些有用的采访句型，要求学生选取课堂所获取的两方面知识其一来完成采访的小对话，巩固和操练课堂所学关于环境问题的一些简单知识。
