13．Scientists say they have discovered a promising treatment for sleeping sickness，a killer disease that infects（感染） about 60，000people in Africa a year．
British and Canadian experts say drugs could attack the parasite（寄生蟲） causing the illness needs to survive．They say the drug could be ready for human medical test in about 18months．
The disease，spread by the bite of a fly，is caused by a parasite attacking the central nervous system．It has similar symptoms（癥狀） to malaria（瘧疾），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 50，000and 70，000cases of the disease a year，with a further 60million 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 20patients and the other is costly，only partially effective and requires long-time hospital treatment，the scientists said．

分析 本文是一篇科普文．講述了科學(xué)家發(fā)現(xiàn)一種新的治療方法，用來治療昏睡癥．這種藥品通過攻擊人體內(nèi)造成昏睡癥的寄生蟲起作用．這種藥物將在18個(gè)月后在人體進(jìn)行試驗(yàn)．昏睡癥主要爆發(fā)在非洲，一年大約有6萬人感染．主要傳播方式為蚊蟲叮咬．癥狀類似瘧疾，感染后會(huì)攻擊人類的中央神經(jīng)系統(tǒng)．這一項(xiàng)新的治療方式讓治愈昏睡癥成為可能，是科學(xué)上的一次巨大突破．
解答 57．答案B．詞義猜測(cè)題．從最后一段的句子"The research in Dundee was backed by partners at the University of York in England and the Structural Genomics Consortium in Toronto，Canada"，可知這個(gè)研究受到紐約大學(xué)的合作伙伴支持．選B．
58．答案D．推理判斷題．從倒數(shù)第二段的句子：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．可知世界健康組織認(rèn)為疾病在非洲傳播的很快．選D．
59．答案D．文章出處題．這篇文章講的是治療睡眠疾病的藥物，就是說是出自藥品的報(bào)紙．選D．
60．答案B．細(xì)節(jié)理解題．從第三段的句子：Left untreated，it moves to the brain，resulting in mental confusion and final death可知這種病會(huì)導(dǎo)致精神失常．選B．
點(diǎn)評(píng) 科普類文章的閱讀，要特別留意文章開頭或結(jié)尾，學(xué)會(huì)找主旨句．根據(jù)不同的題型，選用不同的閱讀策略．詞義猜測(cè)題一定要結(jié)合整句話，瞻前顧后，留意相似詞及反義詞．
