Question

Unlike many other boys of his age who are often addicted to PC games, he is _______ on outdoor activities in the mountains.

A．eager

B．starving

C．keen

D．fond

Answer 1

C

试题分析：考查形容词的区分。句义：不像许多沉溺于网络游戏的他这个年龄段的孩子，他喜爱爬山。把握关键词：on 构成短语：be keen on 喜爱，而be eager to do 渴望做某事，be starving to do 渴望做某事，be fond of 喜欢，所以C正确。
