我们来看下面这一句话：
Please take the airport shuttle bus when you leave the aircraft and it will take you directly to the arrival hall.
请您下飞机后乘坐机场专线车,它会直接送您到到达大厅.
从上例句我们可一看到,
“专线巴士”的英语是“
shuttle bus”.
“shuttle”意为“a plane,bus,or train that makes regular short journeys between two palces”.因此,“shuttle bus”也可以称作“穿梭巴士,班车”,顾名思义就是指“定点穿梭往来两处或者多个地方”,和“专线巴士”同义.
除此之外,“shuttle bus”还可以指“区间车”,表示“a train or bus travelling only part of its normal route”.
