核心问题
Four score and seven years ago our fathers brought forth on this continent a new nation...八十七年前我们的先辈在这块大陆上建立了一个新的国家…… four score 是否可改为 four scores?
词典解答
score(20) 与确切的数字连用时, 是一个零复数的数量词 (虽在语义上是复数, 但不能加-s), 它的用法相当于 head(200 head of cattle = 200 头牛)、horsepower(马力) 和 hertz(赫兹) 等。当用 score 表示 “许多” 时, 则可用 scores of 结构 (参见 dozen)。请对比:
-
three score and ten years 70 年
-
I've been there scores of times. 我去过那里许多次。
-
‘How many people were there?’‘There were scores(of them).’ “那里有多少人?”“有很多(人)。”
-
Scores of people went there in the first few days after its opening. 开张后的头几天，许许多多的人去那家餐馆吃饭。
