3.Malaria,the world's most widespread parasitic (寄生虫引起的)disease,kills as many as three million people every year-almost all of whom are under five,very poor,and African.In most years,more than five hundred million cases of illness result from the disease,although exact numbers are difficult to assess because many people don't (or can't) seek care.It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment,and what they often get no longer works.In countries like Tanzania,Mozambique,and the Gambia,no family,village,hospital,or workplace can remain unaffected for long.Malaria starts suddenly,with violent chills,which are soon followed by an intense fever and,often,headaches.As the parasites multiply,they take over the entire body.Malaria parasites live by eating the red blood cells they infect.They can also attach themselves to blood vessels in the brain.If it doesn't kill you,malaria can happen again and again for years.The disease is passed on to humans by female mosquitoes infected with one of four species of a parasite.Together,the mosquito and the parasite are the most deadly couple in the history of the earth and one of the most successful.Malaria has five thousand genes,and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control.Studies show that mosquitoes are passing on the virus more frequently,and there are more outbreaks in cities with large populations.Some of the disease's spread is due to global warming.
For decades,the first-choice treatment for malaria parasites in Africa has been chloroquine,a chemical which is very cheap and easy to make.Unfortunately,in most parts of the world,malaria parasites have become resistant to it.Successful alternatives that help prevent resistance are already available,but they have been in short supply and are very expensive.If these drugs should fail,nobody knows what would come next.

分析 本文是一篇科教类阅读,文章主要介绍了痢疾对人的健康的危害,分析了人们患疟疾的原因,以及疟疾广泛传染的原因和痢疾的治疗方法.但由于新的治疗疟疾的药物缺乏并且很贵,所以大多数人不能用新的治疗方法治疗.
解答 67-70 ACDB
67.A推断细节题.根据第一段中的"It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment,and what they often get no longer works."可知许多人不进行治疗的原因是他们太穷,没有钱治疗疟疾.故选A.
68.C细节理解题.根据第二段中的"Malaria parasites live by eating the red blood cells they infect."可知人们患疟疾的原因是他们的红血球受到了感染.故选C.
69.D细节判断题.根据第二段中的"Malaria has five thousand genes,and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control."可知疟疾基因有五千,它能迅速改变来保护自己,并且抵制新型病毒,它的这些能力已变得几乎不可能被控制.由此可知,疟疾广泛传染的原因是它有保护自己和抵抗新药的能力.故选D.
70.B细节推断题.根据最后一段中的"Successful alternatives that help prevent resistance are already available,but they have been in short supply and are very expensive."可知由于新的治疗疟疾的药物缺乏并且很贵,所以大多数人不能用新的治疗方法治疗.故选B.
