  • 词义辨析

    scan, browse, leaf, read

    这四个词都有“读”的意思。它们之间的区别是:browse指“泛读”“浏览”,其目的在于挑选,有时也引申为采购其他物品; leaf一般指快速翻动,其目的只看看关键性的词汇或段落,多与through连用; 而scan则指迅速阅读一篇文章以便能抓住其主要内容,其目的性很强,也比leaf和browse严肃; 而read属于普通用语,应用十分广泛,既可指“泛读”“浏览”,也可指“朗读”“默读”“精读”。例如:
    There was no time to read the whole magazine so I just browsed through the pages.由于没有时间读完整本杂志,所以我只是随便翻阅了一下。
    She often browses in dress shops during her lunch hour.她利用午餐休息时间经常逛逛服装店。
    He quickly leafed through the phone book to find the numbers of a few hotels.他很快地翻阅着电话簿查找一些饭店的电话号码。
    She scanned the list of names to see if hers was on it.她粗略地看了一下名单,想知道是否有她的名字。

    read,devour,scan,skim

    这些动词均有“读、阅读”之意。
    read最普通用词,含义广泛。既指朗读又可指默读。
    devour指贪婪地读,暗含对某些作者或作品迷恋之义。
    scan指快速扫视文章等以抓其要旨或找寻某一具体信息。
    skim指略读或浏览。
