We went to Shanghai by a large ship. 注意,汉语说”步行”,英语习惯上用on foot, 而不用 by foot。 (2) 表示在旁边,如: Mary sits by me. (3) 注意以下表示方式的有用表达,其中不用冠词或其他限定词: by phone 用电话 by telegram 用电报 by letter 用信件 by express 用快件 by air mail 用航空邮件 by ordinary mail 用平信 by post 用邮寄 by radio 用无线电 by hand 用手工 by machine 用机器 *注意下面两例用by与用with的区别: The letter was written by hand. 这封信是用手写的(即不是打印的)。(by hand表示一种抽象的手段,是无形的,注意其中没用冠词或其他限定词) I write with my hand, but he writes with his mouth. 我用手写字,但他却用嘴写字。(with one’s hand表示一种具体的工具,是有形的,注意其中用了物主代词) (4) 后接v-ing表示行为的方式或手段,这是一种常用表达。如: He makes a living by teaching. 他以教书为生。 Lock this door by turning the key twice to the left. 锁这扇门要把钥匙向左转两圈。 2. take的用法 (1) take表示乘(交通工具) Shall we go there by bike or take a taxi? They usually take a bus to work. (2) 常常和it连用,it在句子中作形式主语,真正的主语是后面的
