单选题 According to the author, languages whether "civilized or not" hate ______.

【正确答案】 C
【答案解析】[解析] 事实细节题。原文说Most languages of uncivilized groups are... extremely complex, delicate, and ingenious pieces of machinery for the transfer of ideas,既然它们传播思想的方式很复杂、微妙和有独创性,那么他们的方式就应该是不同的,排除[A]。原文只说他们在sound patterns和grammatical structure方面不落后于西方语言,并且十分丰富,但没有说它们有增加sound patterns和grammatical structure的潜力,排除[B]和[D]。原文第三段说All languages seem to possess the machinery for vocabulary expansion...,[C]是对此的同义转述。
