问题描述:

One evening,after he had supper,he wanted to do his homework.But he couldn’t find his pen.So he had to buy ( )A.the otherB.anotherC.else one.这里是another还是the other?

这题只能选B,
因为你要买的钢笔是随意的一枝,事先并没有说的是哪一支,只是许许多多中的一个,表示泛指,所以只能用another.另一个
而the other表示的是特定的两者中的另一个,如:
I have two pens ,one is black,the other is red.
