C．cnsidered D．mentined

C．useful D．regretful
答案 C
解析 根据下文的条件状语从句“if yu are using them fr yur Gd-given purpse”可以判断，本空应该是积极词汇。尽管peaceful也是积极词汇，但是在本文中没有任何依据，故答案为C。

eq \x(语篇解读 作者和大猩猩突然面对面接触，谁更害怕呢？)
51．答案 wh/which
解析 考查宾语从句的引导词。句意为：我不确定谁(哪一个)更害怕，是我还是那只不知从哪里突然冒出来的雌猩猩。
52．答案 the

53．答案 ludest
解析 考查副词的比较等级。由空前的the以及空后的all可知要用最高级。
54．答案 lking
解析 考查非谓语动词之动名词。avid ding sth. 避免做某事。avid后面可以接动名词作宾语，不能接不定式作宾语。
55．答案 challenged
