第23题单选 填入(23)处的最佳答案是()。
A. when
B. while
C. since
D. because

解析：这里引用达尔文所说的话。when和while都表示“当……时候”的意思，但while 有“与……相反”的意思，翻译成“然而，却”。since和because表示原因。根据上下文，这里是说人类与动物不一样，人类会脸红，而动物却不脸红。应选择表示相反的词。
第24题单选 填入(24)处的最佳答案是()。
A. on
B. in
C. at
D. of
答案：C
解析：at a loss是固定词组，表示茫然。这部分是说，达尔文指出人类会脸红而动物不会的时候也是茫然的，说不出其原因。

A. suggestion
B. advice
C. solution
D. question
答案：A

A. apparently
B. completely
C. awkwardly
D. increasingly
答案：D
解析：apparently意为“明显地”;completely意为“完全地”;awkwardly意为“危险地，不舒服地”;increasingly意为“日益地”。根据原文，社会在发展，社会交往肯定也是日益复杂。
第27题单选 填入(27)处的最佳答案是()。
A. moods
B. senses
C. emotions
D. tempers
答案：C
解析：mood意为“情绪、心情”;sense意为“感官”;emotion意为“情感”;temper意为“脾气”。原文列举了如guilt(愧疚)、shame(羞愧)、embarrassment(尴尬)等感觉。这些显然不属于sense(感官)和temper(脾气)，排除。mood和emotion的区别在于，mood表示就某种事件或某段时间影响下所产生的心情或情绪，emotion表示主观上的下意识的感觉。原文在分析人类脸红的原因，从人类自身的情感着手。所以，这里应是emotion。
第28题单选 填入(28)处的最佳答案是()。
A. privileged
B. embarrassed
C. energetic
D. attractive
答案：D
解析：privileged意为“享有特权的”;embarrassment意为“尴尬”;energetic意为“充 满活力的”;attractive意为“有吸引力的”。根据原文空格后的“or socially desirable(社交上更合适)”判断，attractive(有吸引力的)最恰当：人类的脸红可能使 人更具有吸引力或者说社交上更合适。
