Question

Malaria, the world's most widespread parasitic(寄生蟲引起的) 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 passed on to humans by female mosquitoes infected with one of four species of 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

試題分析：文章介紹痢疾對人的健康的危害，分析人們患瘧疾的原因，瘧疾廣泛傳染的原因和痢疾的治療方法。
1.推斷細節(jié)題。根據(jù)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.”可判斷出許多人不進行治療的原因是他們太窮，沒有錢治療瘧疾。選C。
2.細節(jié)題。根據(jù)第二段中的“Malaria parasites live by eating the red blood cells they infect.”可判斷出人們患瘧疾的原因是他們的紅血球受到了感染。選C。
3.細節(jié)題。根據(jù)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.”可判斷出瘧疾廣泛傳染的原因是它有保護自己和抵抗新藥的能力。選D。
4.細節(jié)推斷題。根據(jù)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.”可推斷出由于新的治療瘧疾的藥物缺乏并且很貴，所以大多數(shù)人不能用新的治療方法治療。選B。
5.正誤判斷題。根據(jù)短文的內(nèi)容可判斷出短文沒有涉及“做什么來使人們長時間不感染？”選D。
考點：考查健康類短文
