large quantities of food farmland ____ house and apartments in the past twenty years

题目

large quantities of food farmland ____ house and apartments in the past twenty years
A have converted to build B have been converted to building C has converted to build
D has been converted to building

答案

B
quantities of +名词时,后面的谓语的单复数于quantity一致,quantity是单数 后面谓语动词就用单数
quantity是复数(也就是quantities) 后面谓语动词就用复数
又因为food farmland 是被转变的,所以用被动选B
