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.

57.The word backed in the last paragraph probably meansB.
A.conducted     B.supported   
C.believed      D.managed
58.What the World Health Organization said suggested thatD.
A.a(chǎn)bout 60000people died of the disease each year
B.a(chǎn)bout 60000people were cured of the disease each year
C.600million people are likely to get infected
D.the disease is spreading fast in Africa
59.We can read this passageD.
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
60.We can learn from the passage thatB.
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.a(chǎn)mong 200people infected with the disease,5may die because of the old drug
D.Professor Paul Wyatt may be a professor at the University of York.

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(lái)治療昏睡癥.這種藥品通過(guò)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(wàn)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.

1.The Washington-based think tank's (智囊機(jī)構(gòu)的)"Vital Signs 2007-2008"report points out global patterns ranging from rising meat consumption to Asian economic growth are linked to the broader problem of climate change."I think climate change is the most urgent challenge we have ever faced,"said Erik Assadourian,director of the Vital Signs project."You see many trends in climate change,whether we are talking about grain production which is affected by droughts and flooding.Or meat production as livestock production makes up about 20 percent of greenhouse gas emissions(排放),"he told reporters in a telephone interview before the report's release.
Assadourian said the key message of the report was that unsustainable consumption patterns were responsible for climate change linked to carbon emissions  and other ecological woes.He said of the 44 trends tracked by the report,28 were"pronouncedly bad"and only six were positive.The trends range from the spread of avian flu(禽流感) to the rise of carbon emissions to the number of violent conflicts.The growing use of wind power is among the few trends seen as positive.
Some of the points highlighted in the report include:
--Meat production hit a record 276 million metric tons (43 kilograms or 95 pounds per person) in 2006.
--Meat consumption is one of several factors driving rising soybean demand.Rapid expansion of soybean plantations in South America could displace(擠走) 22 million hectares (54 million acres) of tropical forest and savanna (熱帶草原) in the next 20 years.
--The rise in global seafood consumption comes as many fish species become scarcer.
Other analysts and think tanks have focused on different trends they say mean less cause for alarm.For example,they point out that while more wood is being removed from forests on a global scale,many parts of Europe and North America have experienced reforestation in recent decades.

53.The best title for this passage would beC.
 A.Greenhouse Gas Emissions              B.Global Consumption Patterns
 C.Consumption and Climate Change        D.Economic Growth and Carbon Emissions
54."Vital Signs 2007-2008"report mainly concerns aboutB.
 A.how to protect the earth
 B.the unsustainable consumption and other trends causing climate change
 C.how to stop climate change
 D.the negative trends of climate change
55.The author of the passage mentions two specific positive trends which are linked to climate change.They areD.
 a.Asian economic growth           
 b.Meat production reaching the highest record
 c.more and more seafood consumed by people 
 d.the growing use of wind power
 e.the reforestation being made in some parts of the world
 A.a(chǎn)c.  B.bd.  C.a(chǎn)d.  D.de.
56.From the passage we can conclude thatA.
 A.less livestock production will do good to climate change
 B.more soybean demand will have a good effect upon climate change
 C.climate change will cause many fish species scarcer and scarcer
 D.only by planting more tress can we stop weather from changing worse and worse.
