Question

by a bus 与 by bus 的区别

Answer 1

这两种表达方式都对,但各有不同的意思.

by bus 是出行的方式,区别于 by boat、by train、by air 等等

by a bus 则是表示句子所描述的行为或动作发生的方式,具有特殊性,例：

He ended up getting hit by a bus driving the wrong way near the hospital,but survived.

All the visitors were transported from the flooded area to the hotel by a bus.
