下面两句用的都是单数,但可以用复数吗?
One plus six equals seven. 一加六等于七。
Since when does the $42 plus $5 service charge come to $48? 从什么什候开始42美元加5美元的服务费等于48美元了?
A plus B作主语时,谓语动词用单数还是用复数取决于其中的“A”是单数还是复数(与“B”的数无关)。比较:
His pension plus his earnings comes to 9 000 dollars. 他的养老金加上他的收入共9 000美元。
His earnings plus his wife’s pension come to 9 000 dollars. 他的收入加上他妻子的养老金共9 000美元。
