Malaria is one of the three most prevalent serious diseases in the world.The others are tuberculosis and AIDS. Nearly 500 million people are infected worldwide each year. More than one million die. According to UNICEF, the UN’s children’s organization, more than 90 percent of all malaria cases are in sub-Saharan Africa.Two thousand African children die daily from the disease. Dr. Patrick Kaucher is with the Centers for Disease Control and Prevention. "In rural Africa, one out of every five children born doesn’t survive until his fifth birthday." Malaria is transmitted from person to person via mosquitoes that carry the parasite. Malaria rapidly destroys red blood cells, which deliver oxygen and nutrients to the rest of the body. The disease is preventable and treatable, but most of Africa does not have adequate resources to do either.
选项
A、Mosquitoes breed very quickly.
B、Mosquitoes carry parasites.
C、It destroys red blood cells.
D、It is an epidemic.
答案
B
解析
为什么疟疾会传染?“Malaria is transmitted from person to person via mosquitoes that carry the parasite”,这句话交代了原因。之所以传染是通过蚊子传播寄生虫而导致的。b项正确。a项只是说蚊子繁殖速度快,没说明其携带寄生虫,有一定迷惑性。c、d两项很容易辨别,都不符合题意。
