The word face has more than ten meanings, but diachronically it has one primary meaning, which is（ ）.
A、a surface of a thing
B、the appearance
C、the front of the head
D、the expression of the countenance
【正确答案】：C
【题目解析】：本题考查face的原始意义。从历时角度来看，多义关系是一个词的语义结构发展变化的结果。例如face的原始意义（primary meaning）指的是the front of the head，派生意义（derived meaning）包括the expression of the countenance；a surface of a thing；the appearance等等。故C选项符合题意。
