The semantic unity of idioms is reflected in the （ ） relationship between the literal meaning of each word and the meaning of the idiom as in “rain cats and dogs”.
A、illogical
B、logical
C、mutual
D、natural
【正确答案】：A
【题目解析】：习语的语义整体性也可体现在每个词的字面意义和习语的意义之间不合逻辑的关系中。如“下倾盆大雨（rain cats and dogs）”的意思是雨下的很大（rain heavily），而这个习语的字面意义（下猫和狗）却是说不通的。
