请问专家:当 a flock of...用作主语时,其后的谓语动词用单数还是复数?
A flock of wild geese _______ flying overhead.
A. was B. were
当 a flock of...用作主语时,其后的谓语动词用单数或复数都可以。
用单数——将其视为一个整体来考虑;
用复数——侧重考虑其中的个体。
例句:
A flock of birds hovers around the farm. 一群鸟绕着农场盘旋。(搭配词典)
A flock of geese were passing overhead. —群雁从头顶飞过。(韦氏高阶)
所以网友的这道题,选单数或复数均可以。
赞同蒋老师的解答,当 a flock of...用作主语时,其后的谓语动词用单数或复数都可以。
另外,a pack of...“一群;一帮”也是如此,作主语侧重整体时,谓语动词用单数;若侧重个体,谓语动词用复数。如:
A pack of reporters were waiting outside. 一群记者正在外面等着。
A pack of journalists was waiting outside the White House. 一群记者正在白宫外面等着。
