问题 单项选择题

喜欢甜味的习性曾经对人类有益,因为它使人在健康食品和非健康食品之间选择前者。例如,成熟的水果是甜的,不成熟的水果则不甜,喜欢甜味的习性促使人类选择成熟的水果。但是,现在的食糖都是经过精制的。因此,喜欢甜味不再是一种对人有益的习性,因为精制食糖不是健康食品。
以下哪项如果为真,最能加强上述论证( )

A.喜欢甜味的人,在含食糖的食品和有甜味的自然食品(例如成熟的水果)之间,更可能选择前者
B.绝大多数人都喜欢甜味
C.有些喜欢甜味的人,在一道甜点心和一盘成熟的水果之间,更可能选择后者
D.许多食物虽然生吃有害健康,但经过烹饪则可成为极有营养的健康食品

答案

参考答案:A

解析: 题干中论述的重点是“但是”之后的结论性观点,即喜欢甜昧不再是对人有益的习性,因为精制食糖不是健康食品。要加强这个观点就必须指出人在选择食品时选择含有精制食糖的食品而不是自然食品,精制食糖不是健康食品,人们选择了不健康食品,才能说明喜欢甜味的习性对人不再有益了。故选A。
