随着科技的突飞猛进以及电脑资讯的普及，科学术语、电脑词汇与日俱增;即使同一个字，有时意思在增加，用途也在扩大。工业或行政上的 input 和
output 和电脑上的意思，哪会完全相同?小孩时期看到在地上跑的 mouse 和现在出现在电脑旁的 mouse，形状相似，但意思也一样吗?
不说特殊用语，就是天天见面的常用字，不管是名词、形容词、动词或副词，十九都是多义词，甚至是多种词类的，既可当名词、动词，又可当形容词，甚至副词。
关于这点，《英语词汇：意思和用法》一文中已举例说明，大家应该记忆犹新，不再重复。
由于一词多义在英语词汇的运用上非常重要，这里不厌其烦地再举一个家喻户晓的常用字 break，以加强我对这点的重视。
作为动词，break 有下列 12 个常用意思：
① 打破、断，如：(a) If you drop the cup, you will break it. (b) The rope suddenly
broke.

promises.

④ 中断、打断，如：(a) The barking of the dog broke our sleep. (b) The stranger

⑩ 爆发，如：If a new world war breaks out, can you imagine the consequences?
11. 突破，如：The soldiers tried to break through the enemy's line.
