问题 单项选择题

The Food and Drug Administration classifies as a cosmetic any product whose ______ purpose is to improve a person's appearance.

A.singular

B.sincere

C.single

D.significant

答案

参考答案:C

解析:single purpose“单一的目的”,指only one; singular“单数的”,singular还有“非凡的,卓越的”的意思,a woman of singular beauty“绝美女子”;sincere“真诚的”,习惯上不用来修饰purpose;significant“重要的”,通常也不与purpose搭配使用。
