英语名词加-s表示复数后,名词前边还可以加数词,如three daughters。在汉语里,指人的名词加表示复数的词尾“们”后,名词前边不能再加确指的数量词,这个句子要么去掉“们”,要么删去“三个”。
In English, a noun pluralazed by the suffixes may also be qualified by a numeral, e.g. three daughters. However, in Chinese, a personal noun with a plural suffix 们 can not be modified by a definite numeral-measure word. Thus the above sentence must dro either 们 or 三个.
