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 (感染). 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.

According to paragraph 1, many people don't seek care because___.

they are too poor

it is unusual to seek care

they can remain unaffected for long

there are too many people suffering from the disease

People suffering from malaria___.

have to kill female mosquitoes

have ability to defend parasites

have their red blood cells infected

have sudden fever, followed by chills

Which of the following may be the reason for the wide spread of the disease?

Its resistance to global warming.

Its ability to pass on the virus frequently.

Its outbreaks in cities with large populations.

Its ability to defend itself and resist new drugs.

It can be inferred from the passage that___.

no drugs have been found to treat the disease

the alternative treatment is not easily available to most people

malaria has developed its ability to resist parasites

nobody knows what will be the drug to treat the disease

Which of the following questions has NOT been discussed in the passage?

How can we know one is suffering from malaria?

How many people are killed by malaria each year?

Why are there so many people suffering from malaria7

What has been done to keep people unaffected for long7

Answer 1

【小題1】A

【小題2】C

【小題3】D

【小題4】B

【小題5】D

解析:

【小題1】這是一道推斷細(xì)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(jìn)行治療的原因是他們太窮，沒有錢治療瘧疾。

【小題2】這是一道細(xì)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。

【小題3】這是一道細(xì)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(hù)自己和抵抗新藥的能力。

【小題4】這是一道細(xì)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。

【小題5】這是一道正誤判斷題。根據(jù)短文的內(nèi)容可判斷出短文沒有涉及“做什么來(lái)使人們長(zhǎng)時(shí)間不感染？”
