The following pairs of words are antonyms. Which pair belongs to relative terms? （ ）
A、male/ female
B、single/married
C、parent/child
D、young/old
【正确答案】：C
【题目解析】：本题考查反义词的类别。Antonyms can be defined as words which are opposite in meaning. They can be classified into three major groups. 反义词可以定义为意义相反的词。它们可以分为三大类。（1）Contradictory terms: They are so opposed to each other that they are mutually exclusive and admit no possibility between them，such as “true – false”矛盾反义词：它们彼此对立，相互排斥，彼此之间不承认任何可能性，如“真-假”。（2）Contrary terms: Antonyms of this type are best viewed in terms of a scale running between two poles or extremes. Antonyms such as “big – small” represent two points at both ends of the pole. 对立反义词：这种反义词最好从两极或极端之间的刻度来观察。反义词如“大-小”代表两端的两点极点。（3）Relative terms: This type consists of relational opposites such as “husband – wife”. Such pairs of words indicate such a reciprocal social relationship. 关系反义词：这类词语由“丈夫-妻子”等关系反义词组成。这样的一对词表明了一种相互的社会关系。A选项male/ female——男/女 ；B选项single/married——单身/已婚；D选项young/old——年轻/老的。故只有C选项父母/孩子属于相互的社会关系，故选C。
