一道SAT语法IS题
(a squadron of newly trained,enthusiastic firefighters from training academies,each year they graduate )to begin work in the nation's cities.
为什么原句不行?要改成 Each year a squadron of newly trained,enthusiastic firefighters graduates from training academies.
a squadron of newly trained,enthusiastic firefighters 谓语为何是单数?
a group of students 难道谓语也是单数吗?
答
一、语法上有一些问题,graduates要和介词from 连用.
二、比较一下,原句比较繁琐,第二个句子简洁,且表述很清楚.
三、第二个句子较原句读起来很顺.
主语是a squadron of ,“一个装甲队”,强调的是整体,而不是个体,因此谓语动词用单数.
主语的单复数决定谓语动词的单复数.
