题型:不详难度:来源:

This pair of socks ______ worn out. I"ll have to buy a new ______.
A.is, oneB.are, onesC.is, pairD.are, pairs

答案
C
解析

试题分析:前半句的主语为单数,中心词是pair,故be动词用is,后半句表示的含义是我想买新的一双,前句出现的数量短语,后半句可以简短地用量词就可以了,本题使用pair,故本题选C。
点评:本题除了数量短语的使用,还要注重被动语态的使用,在英文中可用量词+of+名词来表示数量,如a glass of water和two boxes of apples,被动语态的结构为be+动词的过去分词,有时态、人称和数的变化。
