Which of the following shows degradation of word meaning?（ ）
A、meat meaning from “food” to “flesh of animals”
B、angel meaning from “messenger” to “messenger of God”
C、butcher meaning from “one who kills goats” to “one who kills animals”
D、villain meaning from “a person who worked in a villa” to “an evil or wicked person”
【正确答案】：D
【题目解析】：本题考查词义的降格。词义的降格指的是词从表示褒扬或中性的意义向表示贬义意义的演变过程。meat原义指食物，现义指肉，属于词义的缩小；angel原义指信使，现义指天使，属于词义的升格；butcher原义指杀山羊的人，现义指屠夫，属于词义的扩大；villain原义指村夫，现义降格为恶棍，属于词义的降格。故D选项符合题意。
