In everyday language, engine is usually used when talking about vehicles, but people do also use the word motor, especially in the phrase start/turn off the motor or in the term outboard motor (= on a small boat). Motor is also the term used, especially in British English, to describe many things relating to vehicles. 从专业角度说，engine使用蒸汽、汽油或柴油等热能驱动，motor则是把电能转化成动能，洗衣机等电器即属此类。在日常用语中，engine通常指车辆的发动机，但motor亦有此用法，特别是在短语start/turn off the motor（启动／关掉发动机）和术语outboard motor（舷外发动机）中。尤其在英式英语中，motor亦用以描述许多跟汽车相关的事物，而在美式英语中则用automobile◆ (especially BrE) the motor industry / trade汽车业◆ (NAmE) the automobile industry / business汽车业 ■ unit [countable] a small machine that has a particular purpose or is part of a larger machine 装置；机件；元部件◆a waste disposal unit废物处理器◆the central processing unit of a computer电脑的中央处理器◆an air-conditioning unit空调器■ appliance əˈplaɪəns [countable] (rather formal) a machine that is designed to do a particular thing in the home, such as preparing food, heating or cleaning （家用）电器，器具◆They sell household appliances.他们出售家用器具。◆We repair modern heating appliances of all types.我们修理各种新式加热器。ⓘ Appliances are typically described as electrical, domestic, household or kitchen appliances. 最常用来描述appliance的词有electrical、domestic、household和kitchen。■ contraption kənˈtræpʃn [countable] a machine or piece of equipment that looks strange 奇异的机械；奇异的装置◆She showed us a strange contraption that looked like a satellite dish.她给我们看了一个奇怪的玩意儿，样子像碟形卫星信号接收器。
