Which of the following shows that the influx of borrowings has caused some words to change in meaning?（ ）
A、Bulb is used for "light bulb".
B、The meaning of the word fortuitous changed from “accidental” to “fortunate”.
C、The word pig is used for live animals while pork from French is used for pigs killed and brought to the table.
D、Words like democracy, human rights, revolution have different meanings in different societies.
【正确答案】：C
【题目解析】：本题考查词义变化的语言因素。语言系统的内部因素可以引起语义的变化。比如大量的借词涌入引起了一些词的意义的变化。在诺曼征服之后，很多法语词被借入，于是人们开始用英语中原有的词汇表示动物的名称，而用法语借词来表示动物的肉，例如：pig表示猪，pork表示猪肉。而bulb—light bulb属于词组的缩短；fortuitous—accidental to fortunate属于类比；democracy, human rights, revolution属于非语言因素中的阶级原因。故C选项符合题意。
