A good example of （ ） is the word “manuscript”, which now means “writing by hand or typed with a type-writer or a word-processor”, but its original meaning was “handwriting” only.
A、degradation
B、elevation
C、narrowing
D、extension
【正确答案】：D
【题目解析】：本题考查词义的扩大的概念及例子。词义的扩大也称普遍化，是指词的意义的扩大。这是一个词的词义从表达某一专门意义转化到表示概括意义的过程。manuscript的含义从仅指“手写”转变到“手写或用打字机或文字处理机打字”，这是词义扩大的例子。所以本题选D。
