    Scientists say they have discovered a promising treatment for sleeping sickness, a killer disease that infects(感染) about 60,000 people in Africa a year．
    British and Canadian experts say drugs could attack the parasite（寄生虫） causing the illness．They say the drug could be ready for human medical test in about 18 months．
    The disease, spread by the bite of a fly, is caused by a parasite attacking the central nervous system．It has similar symptoms（症状） to malaria（疟疾）, making it difficult to diagnose．Left untreated, it moves to the brain, resulting in mental confusion and final death
    The "breakthrough" came at the University of Dundee in Scotland, where scientists were offered money to research diseases ignored by major drugs companies．
    Professor Paul Wyatt, director of the programme, said: "This is one of the most significant findings made in recent years in terms of drug discovery and development for ignored diseases."
    He said the research, published in the journal Nature, represented "significant progress" in the development of a full blown drug against the disease．
    The World Health Organization said there are between 50,000 and 70,000 cases of the disease a year, with a further 60 million people at risk of infection．
    The research in Dundee was backed by partners at the University of York in England and the Structural Genomics Consortium in Toronto, Canada．The two drugs currently available to treat sleeping sickness both have problems．One is with side effects that kill one in 20 patients and the other is costly, only partially effective and requires long-time hospital treatment, the scientists said．
    小题1:The word backedin the last paragraph probably means_____.
    A．conductedB．supportedC．believedD．managed
    小题2:What the World Health Organization said suggested that______.
    A．about 60000 people died of the disease each year
    B．about 60000 people were cured of the disease each year
    C．600 million people are likely to get infected
    D．the disease is spreading fast in Africa
    小题3:We can read this passage______.
    A．in the journal Nature
    B．in a newspaper of the University of Dundee
    C．in a book about flies
    D．in a newspaper about medicine
    小题4:We can learn from the passage that______．
    A．big drug companies play an important role in the research of the new drug
    B．people who get infected with the disease are mentally disturbed
    C．among 200 people infected with the disease, 5 may die because of the old drug
    D．Professor Paul Wyatt may be a professor at the University of York

  • 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。
