拳皇97大猪连招:一道1992年的高考英语题（谢谢详解）

Shortly after the accident, two __ police were sent to the spot to keep order. (MET. 1992)

A. dozen of B. dozens C. dozen D. dozens of

(C.)
dozens of 解释为“很多打的”的.

但是，如果具体地说出二打、五打等，则 dozen 后没有 s ，也不用 of:

dozen表示确切数目是除能与a和基数词连用外，还能some; many; several修饰，只是确切数含糊。如：three dozen books 其中dozen不加s,其后也不用of;如果dozen 后有these, those, them, us等词， 表示“范围中的某某”时，其后加of.
如：1. We bought two dozen story books yesterday.
译文：我们昨天买了两打故事书。
2. Three dozen of them are league members.
译文：他们中有三十六人是团员。
[高考考例] 1. Shortly after the accident, two _____ police were sent to the spot to keep order. [NMET2000]
A. dozen of B. dozens C. dozen D. dozens of
[思路点拨]答案为C.此题题干中的空前有数词two修饰，dozen不能加s,其后也不能加of,故选C.译文：事故发生后不久，有二十四个警察被派往现场维持秩序。但如果把题干改为：
Shortly after the accident, two ______ the police were sent to the spot to keep order.则选A。译文：事故发生后不久，这些警察中的二十四个被派往现场维持秩序。
[精讲]dozen 构成dozens of 相当于scores of/ a lot of等表示“许多”
[考例]2. There were ____ flies everywhere in my house.
A. dozens of B. three dozens C. four dozens of D. seven dozen of
析：答案为A. dozens of 表示许多，译文为：我房子里到处都是蚊子。
[聚焦]dozen 常见结构：
（1）基数词/many/ several+ dozen+复数名词；
（2）基数词+ dozen + of sb或基数词+ dozen +of these/ those/ one’s+ 复数名词
（3）dozens of +复数名词
