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] (ratherformal) 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。
