Half of the workers here _____ under 30 _____. A.is/years B.are/year old
Half of the workers here _____ under 30 _____. A.is/years B.are/year old C.is/years old D.are/years of age
为什么是D
第一个空:因为主语是workers,是复数,所以应该用are
第二个空:年龄的表达方式只有3种,一个是i'm xx.一种是i'm xx years old,最后一种是i'm xx years of age.
第一空 前边是半数的工人表示复数肯定用are没有问题撒 排除A C
第二空 year是可数名词 所以要用years 排除B
D项表达正确
首先第一个空,主语是workers,复数,所以用are,不用is,第二个空,30岁的30,也是复数,所以year后面得有s.
这是一个侧重问题。整句翻译是:这里一半的工人都在30岁以下。强调的是这一半的工人(主语)里每个人都是30以下,有一半的人,就用复数啦!至于后面,30years of age=30 years old,这个就不用我多说啦~希望我的解说您能明白~
