请教score和dozen的用法score、dozen作为数词怎样使用?前面加具体数字和笼统数量(many等)有什么区别?后面跟人或物时又有什么区别?望详细一些.不要随便贴个解释!希望有详细一点的用法说明

网友回答

一、dozen表示“ 打,十二个”的意思,而score表示“二十”的意思.
二、两词与数词,a,many,several连用修饰名词复数时,都要用单数,其后的介词of有无均可.但是,习惯上score多与of连用,而dozen很少与of连用,如:two score(of)workers,three score and ten people,several dozen children,many dozen books.
三、两词与of连用(of不省略)时,可用于人称代词宾格(us,you,them)或指示代词(these,those)修饰的名词前,表示所属关系.如:a dozen of these/those pelple,two dozen of them/us,a score of these/those workers.
四、 两词的复数形式与of连用时,表示不确切的数量,意为“许多……,大量的……”.如:dozens of people,dozens of times,scores of people.而some dozen people是“一打左右的人”(大约十二人)与some dozen of people同义.(some)dozen of people是“若干打的人”(几十个人,许多人).
五、除了上述用法之外,还要注意下列习惯用语:(pack)in dozens〔成打(包装)〕,(sell)by the dozen[论打(出售)],in scores(成批的)
练习:1.The woman wanted to buy three____eggs,but there were only two___eggs left inthe shop.
A.scores of;dozens of B.scores;dozens C.score of; dozen of D.score of;dozen
2.The goods are packed in____and shipped in____all over the world.
A.dozens;scores B.scores;dozens C.dozens;score D.score;dozen
3.The teacher wanted to buy two___books,but the salesgirl only sold him___these books.
A.scores of;dozens of B.scores;dozen of C.score of;dozen of D.score of;dozen
答案:1、D 2、A 3、C
======以下答案可供参考======
供参考答案1:
score 二十, dozen 十二
后面接表示人或物的名词的复数.
供参考答案2:
score意为二十,它与dozen, hundred, thousand, million等词一样,前面有确定
数字时,不加s,但可以与介词of连用,但hundred, thousand和million前面
有确定数词时,不能跟of短语。没有确定数词时加s及of表示许许多多。
如: a dozen pencils 一打铅笔
two score years 四十年
a score of eggs 二十个鸡蛋
three hundred students 三百名学生
hundreds of students 数百名学生
The bus can hold two score and ten people. 这辆汽车可以容纲50人。
Scores of people took part in the game. 许多人参加了这次比赛。
dozen1. 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.
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。
