初中英语介词与交通方式专题辅导
1. “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原形，不能用复数，也不能被冠词或物主代词等修饰。如：
My parents often go to work by bus.我父母常坐公共汽车去上班。
He comes here by taxi.他乘出租车来这儿的。
2.“by＋交通路线的位置（地理名词）”表示交通方式，表示“由……途径”。如：bysea（从海路），by water（从水路），by air（由航空；乘飞机），by land（由陆路）等。如：We are going to England by air.我们打算乘飞机去英国。
3. “in＋交通工具名词”表示交通方式。不过此时交通工具名词前须用冠词、名词的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”相同。如：in the plane（taxi，car）＝by plane（taxi，car）
I usually go to school in a（my）car.我通常乘小汽车去上学。
4.用“on＋限定词＋交通工具名词”。也表示“乘；坐”之意，也相当于“by＋交通工具名词”。
不过，on多用于开放式或半封闭式交通工具，而上面同学所说的in则多用于封闭式交通工具。试比较：
Don“t come here on the ship（by ship）.不要乘船来这里。
She goes to the station in a taxi.她乘出租车去车站。
5. “take a（the）＋交通工具名词”表示交通方式，表示“乘；坐”。如：take
a bus（乘公共汽车），take a train（乘火车）等等。
6. “ride＋限定词＋交通工具名词”表示交通方式，意为“骑……”。如：ride a bike（骑自行车），ride a horse（骑马）等。
而ride to表示“骑车（马）去”，相当于go to. . . by. . .。如：Lily rides a bike to her home.（＝Lily goes home by bike.）莉莉骑车回家。
7. “fly to”表示“乘飞机；飞往”，相当于go to. . . by air／plane；“drive to”表示“驱车／开车去”，相当于go to. . . by bus／car／taxi等。
表示“步行去某地”可用“go to＋某地＋on foot”，也可用“walk to＋某地”。如：We go to thecinema on foot.（＝We walk to the cinema.）我们步行去看电影。
