dozen of和dozens of的区别

中考英语
2022/2/4
作单位词时,dozen后接of,表示一打,如:three dozen of eggs.三打鸡蛋。在表“几十个”不确定的泛指数时用dozens of,用法同tens of,hundreds of,thousands of…。如:dozens of/scores of students.好几十个学生。
1.作数量词时,dozen十二个,score二十个。用法与hundred,thousand…等类似。如:
a dozen apples 十二个苹果(一打苹果),
two score chairs四十张椅子,
three hundred people三百个人。
2.作单位词时,score(二十)后可接of,但dozen(一打)后接of很罕见。如:
five score(of)fish一百尾鱼(省略of则score为数量词)
three dozen eggs三打鸡蛋
3.在表“几十个”不确定的泛指数时用dozens of或scores of,用法同tens of,hundreds of,thousands of…。如:
dozens of/scores of students好几十个学生
4.dozens of和scores of前若用some,several,a few,many等词时,dozen和score可去掉“s”(很少保留),同时也去掉of。如:several dozens/scores of people=several dozen/score people
5.当后面有人称代词(you,us,them)时,名词前有定冠词(the)、物主代词(my,your,his,her,their,its)以及指示代词(these,those)限定时,要用“数词+dozen/score+of”,dozen和scores均不加”s”。如:
a dozen of them他们中的十二个
two score of the books四十本书
three score of my sheep我的二十只羊
