Question

the thieves were trying to
当那两个小偷企图乘车逃跑
the thieves were trying to get away in their their car.
使用车 为什么用in 而不用by their their car

Answer 1

表示“乘坐”的两种表示法：
1.by+表示交通工具的名词 名词前不用the/my/his/their等限定词
by只是表示一个抽象的概念“乘坐”
by+car/train/bike/plane/ship
2.in+限定词＋表示交通工具的名词(bus/car/plane等等)＝ by+表示交通工具的名词
实例：
I came here in a/my/his/their car.=I came here by car.
