For the people living in the Nile Basin, the river is their life.This 6,825 km waterway, whose watershed (流域) covers three million square kilometers, flows through mountains, woodlands, lakes and deserts. Its potential for fishing, tourism and shipping is great-but so are its challenges.
Water shortage, already serious in Egypt and Sudan, will soon influence several other countries in the
watershed as well.Today, about 160 million people depend on the Nile River for their living. Within the
next 25 years, the district's population is expected to double, adding to the demand brought about by growth in industry and agriculture. The frequent drought (干旱) adds to the urgency.
Water quality is also a problem. Precious soil is washed out to sea.Wastes from industry and agriculture create pollution. Higher concentrations of salt influence irrigated soils. Waterborne diseases continue unchecked. In areas where it's hot and damp, waterhyacinthschoke off lakes, dams and other sections of the
river, making it difficult for fishing and other businesses to move forward.
Native people along the narrow area of farmland have watched the sand move closer day by day.
They've seen the river change course, and their only source (来源) of water thickened with mud. They're
very poor and have few choices.
But a new program, the Nile Basin Initiative (NBI), is offering very practical assistance. The program is more than just a watermanagement project. It's a plan for the social and economic development of a vast
district: it concentrates on the needs of the poorest of the poor and the environment that supports them.
These are whole ecosystem problems, calling for united solutions (解决办法). Half the Nile Basin's
countries are among the world's poorest nations; yet, somehow, they must find the resources, skills and
political will to overcome these challenges.
1. What are the great challenges the Nile Basin faces?
A. The development of shipping industry.
B. Overfishing of native people.
C. Water shortage and water quality.
D. Increasing population and tourism.
2. The underlined word "hyacinths" ( in Paragraph 3 ) refers to "_____".
A. animals
B. plants
C. rocks
D. salts
3. The program NBI is mainly aimed at _____.
A. preventing water pollution
B. changing the river course
C. improving living conditions of the poor
D. preventing land from becoming desert
4. What would be the best title of this passage?
A. People's Life in Egypt and Sudan
B. Frequent Drought in Egypt and Sudan
C. The Poorest Countries in the Nile Basin
D. The Ecosystem Problems in the Nile Basin

健康环保类阅读

健康环保累阅读概念：

健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。体裁有记叙文、说明文、议论文和各种应用文。

健康环保类文章阅读技巧：

       健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。阅读此类短文要以现象或事物为中心进行思考，理解现象产生的原因、条件和客观规律等。同时要抓住事物的特征、用途和相互关系等。科普环保类文章一般为说明文，从结构上看大致可分为三个部分：
       第一部分一般是文章的首段，主要用来提出文章的主题，即文章想要阐述、说明的主要内容；
       第二部分是文章的主体，可由若干个段落组成，对文章的主题进行展开说明；
       第三部分是结尾段，对文章的主题进行归纳总结。这类文章多用一般现在时，而且一般多使用客观性词语表述。有时为了强调客观性，也常使用被动语态。
       从近几年的考试题来看，科普环保类的文章越来越与人们的实际生活相接近。由于此类文章缺乏故事情节，很多同学对此类文章感到费解。但一般的科普类文章都是就事论事，需要逻辑推理和想象的时候较少，因此此类阅读题也没有同学们想象中的那么难，只要多加训练，就能较好地答题。
【阅读策略】
1、概要(Summarizing)：
      阅完材料后，将所阅材料浓缩，摘要，做出所阅材料的书面或口头梗概。
2、组织(Organization)：
      阅读后根据阅读内容，识别观点、人物、事件之间的关系以及文章的结构关系。如：时间关系、比较或对比关系、相关关系及因果关系等。
