dozen可用复数吗?dozen后要接of吗?你知道dozen的用法吗?请先看下面一道试题:We already have _________ pencils, but we need two _________ pens.A. dozen of, dozen     B. dozens of, dozens    C. dozens of, dozen   D. dozens of, dozen of此题最佳答案为C。关于dozen的复数是否加词尾-s的问题比较复杂,大致原则是:1. 当它与具体数字连用时,既不加复数词尾-s,也不后接介词of。尽管有的词书也有 two dozen of 这样的用例,但这已属过时用法,在考试中应避免,如1992年全国高 lang=EN-US style="FONT-SIZE: 10.5pt; FONT-FAMILY: 'Times New Roman'">1992two dozen of为错误选项:Shortly after the accident, _________ police were sent to the spot to keep order. A. dozens of             B. dozens                  C. dozen of               D. dozen     [D]


2. 当它不与具体数字连用,而是表示不确定的泛指数时,则不仅要加复数词尾-s,而且要后接介词 of,此时可将dozens of(许多,几十)视为习语。如:I’ve been there dozens of times. 我去过那儿几十次。She’s got dozens of boy-friends. 她的男朋友很多。下面一例中的dozens加了复数词尾-s也属为似情况:Pack them in dozens. 按打装袋吧。


3. 当与 a few, several 等数目不很具体的e="FONT-SIZE: 10.5pt; FONT-词连用时,加不加复数词尾-s均可,但需注意:不加复数词尾-s时,其后的介词of可以省略;加词尾-s时,其后介词 of不能省略。如:several dozen (of) pencils=several dozens of pencilsAMILY: 'Times New Roman'">several dozen (of) pencils=several dozen几打铅笔注:英语较少使用many dozen的说法,要表示类似意思可用dozens of。


4. 当它后面的名词受 the, these, those 等特指限定词修饰时,或其后的接的是us, them这样的人称代词时,则此时必须用介词 of。如:two dozen of these eggs 两打这种鸡蛋three dozen of them 它们中的3打注:score, hundred, thousand, million等也具有以上类似用法。
