Question

butter and bread 主谓一致
有道题目Bread and butter_____ what Americans usually have for breakfast.空格处填 is 还是 are 为什么?如果将 bread and butter 改为 the bread and the butter 或者改为 the bread and butter 空格处又该填什么?

Answer 1

bread and butter 抹黄油的面包片为一种食物,动词用单数（is）,如用the bread and the butter为两种食物动词用复数（are）,the bread and butter也看成单数（is）.
