问题 单项选择题

有些人若有某一次厌食,会对这次膳食中有特殊味道的食物持续产生强烈厌恶,不管这种食物是否会对身体有利。这种现象可以解释为什么小孩更易于对某些食物产生强烈的厌食。
以下哪项如果为真,最能加强上述解释( )

A.小孩的膳食搭配中含有特殊味道的食物比成年人多
B.对未尝过的食物,成年人比小孩子更容易产生抗拒心理
C.小孩的嗅觉和味觉比成年人敏锐
D.和成年人相比,小孩子较为缺乏食物与健康的相关知识

答案

参考答案:C

解析: 选项中只有C选项最能加强题干的解释。题干中提到特殊味道,而C选项说小孩的嗅觉和味觉比成年人敏锐,那么对于那些特殊味道会比成年人更加敏感,所以小孩更易于对某些食物产生强烈的厌食。D项认为小孩比成年人缺乏食物与健康的知识,这不能把题干解释的因果关系联系起来,因为即使小孩和成年人一样具有食物与健康的知识,小孩还是可能产生厌食的,因此D不对。正确答案为C。

     Each nation has many good people who help to take care of others. For example, some high school and

college students in the United States often spend many hours as volunteers in hospitals, orphanages or homes

for the aged. They read books to the people in these places, or they just visit them and play games with them

or listen to their problems.

     Other young volunteers go and work in the homes of people who are sick or old. They paint, clean up, or

repair their houses, do their shopping or mow their lawns. For boys who no longer have fathers there is an

organization called Big Brothers. College students and other men take these boys to baseball games or on

fishing trips and help them to get to know things that boys usually learn from their fathers.

     Each city has a number of clubs where boys and girls can go to play games or learn crafts (手艺). Some

of these clubs show movies or organize short trips to the mountains, the beaches, museums or other places

of interest. Most of these clubs use a lot of high school and college students as volunteers because they are

young enough to remember the problems of younger boys and girls. Volunteers believe that some of the

happiest people in the world are those who help to bring happiness to others.
