中学英语语法详解
你平时说在公交车上是用 in the bus 还是 on the bus 呢？还有其他好多交通工具应该用 in 还是 on 呢？
一起来看看下面的内容，把他们分清楚搞明白！
官方解释：
The phrase on the bus is quite standard and normal.
on the bus这个短语是一个很标准很普遍使用的搭配。
The use of on does NOT imply that the person is on the roof. Basically, if the speaker is taking a long trip by bus, that person is said to be on the bus during the entire trip.
这里on的使用，并不是意味着这个人在位置层面的on。基本上，如果一个人说他搭公交车旅行，那么就应该表达成他在旅行中一直是 on the bus 的。
When a person is boarding a bus, we d typically say the person is getting on a bus. (And at the end of the trip, it would also be quite normal to say that person is getting off the bus.)
当一个人要搭乘公交车，我们就会说这个人正在get on a bus。（并且，当他下车时，我们会用get off the bus来表达）
在公交车上on a bus VS in a bus
在公交车上是 in the bus 还是 on the bus 呢？
其实很简单！
记住这一规则轻松区分
↓↓↓
空间的封闭性和空间大小
If there is no compartment involved, you get ON it. (bicycle, motorcycle, skateboard, etc.) (Note: partial compartments, such as those of convertible cars or open-topped boats, count as compartments; pretty much anything where the vehicle at least partially surrounds you.)
如果交通工具没有隔间，你就用on。(自行车、摩托车、滑板等)(注:有不是完整隔间的，如敞篷车、敞篷艇等，也算作隔间；几乎就是有东西遮挡在你周围就算是了。)
以下情况用on
人可以站起身在行走在这个交通工具上
on a bus： 在公交车上
on a train：在火车上
on a plane： 在飞机上
on a bullet train：在动车上
on a subway：在地铁上
on a ship：在船上
有一首儿歌就是就是这么唱的：
The wheels on the bus go round and round, round and round, round and round "
Oddly enough, if the transportation is large enough to allow you to move around freely, you also get ON it. (Bus, train, large boat, passenger plane, etc; anything with an aisle or walkway.)
尽管很奇怪，如果交通工具大到可以让你自由移动，你也用on。（公共汽车、火车、大型船舶、客机等;任何有过道或走道的东西。)
Otherwise, you almost certainly get IN it. (Car, personal aircraft, canoe, etc.)
除此之外，你就用in。（汽车、私人飞机、独木舟等）
in a+ 交通工具
该交通工具空间比较小，人不可以里面直立行走
in a car: 在汽车里
in a taxi：在出租车里
in a helicoptor：在直升机里
在海边by sea VS by the sea
记住下面两个公式：
by+ the +地点
在...旁边
by the sea: 在海边
by the house: 在房子旁边
by the tree: 在树旁边
例句：
The car is parked by the house.
车子停在了房子旁边。

乘坐...
by sea: 乘船
*by means of a ship or ships.
