问题 PASSAGE THREE
What is the purpose of telling the story of the sickest child at the beginning?

选项

答案To prove the power of antibiotics in certain cases.

解析 由题干定位至文章开头两段。第二段第二句提到Antibiotics represent a huge gift in the struggleagainst infant and child mortality…由此可知,抗生素对降低婴幼儿的死亡率是一份大礼,换言之,抗生素在降低婴幼儿死亡率方面很有效,因此,作者的目的是想证明抗生素在某些案例中的效果,故答案为To prove the power of antibiotics in certain cases。
