单选题 People can still talk about Anglo-Saxons today even though they came to Britain in the 5th century. This feature of language is called
[A] Arbitrariness. [B] Duality. [C] Creativity. [D] Displacement.

【正确答案】 D
【答案解析】本题考查语言学基本知识。语言有四种性质：Arbitrariness(任意性)，Duality(二重性)，Creativity(多产性)和Displacement(移位性)。移位性指我们用语言可以表达许多不在场的东西。题干是“人们如今仍然可以讨论5世纪时期的盎格鲁-萨克逊人”，即是指用语言表达不在场的东西，也就是语言的移位性。故本题正确答案为[D]。
