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、Prevalent Diseases in the World
B、Disease Control and Prevention
C、Malaria -- A Fatal Disease
D、Sub-Saharan African Children

答案 C

解析 本题主要考查考生是否能从宏观上把握全文主旨,从而选出文章的最佳标题。a项的范围显然大于本文所谈的范围,本文主要指“malaria”(疟疾)这一致命性疾病,所以不符合。b项只是在文中提到关于疟疾是可预防和治愈的,但非洲还没足够的资源,还是突出疟疾这一疾病的致命性特点,所以该项不符。d项说亚撒哈拉非洲地区的儿童,而本文主要谈疟疾疾病问题,非洲地区举例主要是说明该疾病的严重性,显然该项不符合。所以c项是选择项,本文主要谈论疟疾这一致命性疾病,通过举例等说明其危害。
