Which of the following is true about sound and meaning?（ ）
A、The relationship between sound and meaning is not conventional.
B、The symbolic connection between sound and meaning is never arbitrary.
C、In different languages the same concept can be represented by the same sound.
D、There is no logical relationship between the sound which stands for a thing or an idea and the actual thing and idea itself.
【正确答案】：D
【题目解析】：本题考查词的声音与意义的正确说法。声音和意义之间是约定俗成的；声音和意义间的象征性联系是任意的；在不同的语言中，相同的概念可以用不同的声音来表示；代表事物或思想的声音与实际事物和思想本身之间没有逻辑关系。故A、B、C项均不正确，D选项符合题意。
