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、They deliver oxygen and nutrients to the rest of the body.
B、They kill the mosquitoes.
C、They are resistant to malaria.
D、They are nutrients.
答案
A
解析
为什么红细胞对人们很重要?通过后文可以听出,疟疾之所以高致病主要是摧毁了人体中的红细胞。“Malaria rapidly destroys red blood cells, which deliver oxygen and nutrients to the rest of the body”,此句还交代了红细胞的作用在于向人类传送氧气和营养物质,所以a项符合题意。
