首先介词in ,on和by都可以与表示交通工具的名词搭配,表示交通方式,但其用法各不相同:
1.用“by+交通工具名词”表示交通方式.此时交通工具的名词只能用单数,不能用复数,也不能被冠词或物主代词等限定.如:by bike(骑自行车),by bus(乘公共汽车),by car(乘出租车),by train(乘火车),by ship(乘轮船),by plane(乘飞机)等.如:
They often go home by bus.他们经常坐公共汽车回家.
I come here by taxi.我乘出租车来这儿的.
He goes to work by bike.他骑自行车去上班.
2.用“by+交通路线的位置”来表示交通方式.如:by land(从陆路),by water(从水路),by sea(从海路),by air(乘飞机)等.如:
They go to England by air.他们乘飞机去英国.
3.用“in(on)+交通工具名词”.此时交通工具名词前必须有冠词、名词所有格形式或形容词性物主代词等限定词修饰.其用法与“by+交通工具名词”相似.如:
He often goes to school on a(his)bike.他经常骑自行车去上学.
Don't come here on /in the ship.不要坐船来这里.
We go there in a car.我们乘小汽车去那里.
4.用“take a(the)+交通工具名词”表示交通方式.如:take a bus(乘公共汽车),take a train(乘火车),take a ship(乘轮船),take a plane(乘飞机);但“骑自行车”要用 ride a bike来表示.如:
Will you take a bus to go there?你乘汽车去那儿吗?
5.表示“步行去某地”,可用下列两种句式:
(1)go to +某地+ on foot.如:
She g oes to w ork on foot.她步行去上班.
注意:on foot不可说成 on feet,on a /the /my foot,by foot等.
(2)walk to +某地.如:
He walks to school every day .=He goes to school on foot every day .
他每天步行去上学.
注意:
a.walk不可与on foot连用.如上述例句不可说成:
He walks to school on foot every day .
b.walk to后接地点副词 here,there,home时,介词to要省去.如:
I usually walk home.我通常步行回家.
此外,同学们还应知道:
我们在对交通方式提问时要用特殊疑问词how.如:
Mr Green goes to the post office by bike.(对划线部分提问)
→How does Mr Green go to the post office?
Ann is going shopping on foot.(同上)
→How is Ann going shopping
