一般的,形容词比较级前不用冠词,但当形容词比较级之后有of the two,则其前必须加定冠词the
He is the taller of the two. 他是两人中较高的。
有时of the two并非直接出现在句中,但可分析出含有of the two的意思,这时也必须用the
Of gold and silver, the former is the more precious. 金银之中,以金为贵。
试比较:
Which is more nourishing, maize or wheat? 玉米和小麦哪个更有营养?
Maize is the more nourishing (of the two). 玉米是(两者中)比较有营养的。
Maize is more nourishing than wheat. 玉米比小麦更有营养。
当比较级形容词后跟有一个单数名词时,前需加不定冠词a(n)
Iron is a more useful metal than gold. 铁是比黄金更为有用的金属。
