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、Nearly 500 million people are infected worldwide each year.
B、90 percent of children died from malaria each year.
C、1/5 children in rural areas died before their fifth birthday.
D、Children are infected with Aids and tuberculosis.

答案 C

解析 该题主要考查学生对数字以及文章细节的获取能力,有一定难度。首先要弄清题意。a项虽然在文中出现过,但是并不是指非洲儿童,有迷惑性。b项是联合国儿童基金会所得出的调查结论,指亚撒哈拉地区的儿童,而且文中说是90%多,所以不符合题意。c项正确。d项是文章开头提出和疟疾对比的疾病,不符合题意。
