a queue of…的意思是“一长列…”“排着队的一列…”,其后接复数名词。
当 a queue of…用作主语时,谓语动词通常用单数(即视为整体)。如:
A queue of cars was held up by the traffic lights. 一长列汽车被红绿灯截住了。
There is a queue of people for new houses. 有一长队的人等着要新房。
There was a queue of people waiting patiently for the bus to arrive.人们排着队耐心等待公共汽车来。
但有时谓语动词也用复数(即将其视为整体),不如用单数普通。如:
A queue of people were waiting for the last bus. 一群人在排队等末班车。
A queue of passengers were waiting to board the boat. 一排旅客正等着上船。
