单项选择题
Few people realize how rich that area is. It is a land of treasure ______ treasure.
A. piled on
B. derived from
C. turned over
D. increased by
答案
参考答案:A
解析: 本题是说很少有人认识到那个地区有多么富裕,它是一个堆积在财宝上的宝地。A项“pile on堆积(pile things one on top of the other;pile up堆积,积累)”符合题意。其他三项中,derive(sth.)(from)v.“起源于;衍生;取得,得到”;turn sth.over to sb.移交“;turn sth.over in the mind”仔细考虑“;increase v.”增加“(不说increase sth.by sth.),都与题意不符。
