【正确答案】：
ANTONYMS CAN BE DEFINED AS WORDS WHICH ARE OPPOSITE IN MEANING. THEY CAN BE CLASSIFIED INTO THREE MAJOR GROUPS.CONTRADICTORY TERMS: THEY ARE SO OPPOSED TO EACH OTHER THAT THEY ARE MUTUALLY EXCLUSIVE AND ADMIT NO POSSIBILITY BETWEEN THEM，SUCH AS “SAME - DIFFERENT”.CONTRARY TERMS:ANTONYMS OF THIS TYPE ARE BEST VIEWED IN TERMS OF A SCALE RUNNING BETWEEN TWO POLES OR EXTREMES. ANTONYMS SUCH AS “HOT-COLD”REPRESENT TWO POINTS AT BOTH ENDS OF THE POLE AND CAN ACCOMMODATE A MIDDLE GROUND BELONGING NEITHER TO ONE POLE NOR TO THE OTHER. WE CAN HAVE WARM OR COLD. RELATIVE TERMS: THIS TYPE CONSISTS OF RELATIONAL OPPOSITES SUCH AS “PARENT-CHILD”.SUCH PAIRS OF WORDS INDICATE SUCH A RECIPROCAL SOCIAL RELATIONSHIP THAT ONE OF THEM CANNOT BE USED WITHOUT SUGGESTING THE OTHER. IF A IS THE PARENT OF B, THEN B IS HIS CHILD.
【题目解析】：反义词可以定义为意义相反的词。它们可以分为三大类。相互矛盾的术语：它们彼此对立，相互排斥，彼此之间不承认任何可能性，例如“相同-不同”。相反的术语：这种类型的反义词最好从两极或极端之间的尺度来看。反义词“hot cold”代表极点两端的两点，可以容纳既不属于一个极点也不属于另一个极点的中间地带。我们可以吃热的或冷的。相对词：这类词是由“亲子”等关系对立词构成的，这类词对表示的是一种相互的社会关系，一种词与另一种词不可兼用。如果A是B的父母，那么B是他的孩子。
