scan的注释:

20. In the 1969 edition of The American Heritage Dictionary a dead issue was buried by our Usage Panel, 85 percent of whom thought it was acceptable to use scan in the sense “to look over quickly,” though the note stated that this was less formal usage. The usage issue was raised because scan in an earlier sense meant “to examine closely.” From a historical perspective it is easy to see how these two opposite senses of scan developed. The source of our word, Latin scandere, which meant “to climb,” came to mean “to scan a verse of poetry,” because one could beat the rhythm by lifting and putting down one's foot. The Middle English verb scannen, derived from scandere, came into Middle English in this sense (first recorded in a text composed before 1398). In the 16th century this highly specialized sense having to do with the close analysis of verse developed other senses, such as “to criticize, examine minutely, interpret, perceive.”From these senses having to do with examination and perception, it was an easy step to the sense “to look at searchingly” (first recorded in 1798), perhaps harking back still to the careful, detailed work involved in analyzing prosody. But a thorough search can change into a quick one, as it seems to have done in the case of the verb scan.
在1969年版的美国传统词典 中,我们的用法委员会放弃了一个已废弃的争议, 其中85%的人认为scan 意为“快速浏览”是可接受的, 虽然注释上说这是非正式的用法。之所以这么用是因为scan 在较早的意义上表示“仔细检查”。 从历史的角度了解scan 的两个相反意思如何发展是容易的。 这个单词的词源是拉丁语scandere ,意为“攀登”,后又演化为“标出诗之格律”, 因为人们可以通过抬起或放下脚来打拍子。中世纪英语动词scannen 即是在这个意义上从 scandere 转化而来的(首次被记载在一本1398年之前编辑的教科书上)。 在16世纪这个已经高度专门化并且用来表示仔细分析诗歌的词语又发展出了其它的意项,如“批评、细致入微地检查、翻译或理解”。从这些表示检查和察觉的意思,很容易就过渡到“细察”(1798年首次被记载)的意义,也可能返回到仔细分析诗体的细微工作。但就象这个动词scan 一样,彻底地搜查可能变成快速地浏览
