An automobile is a car. (mainly 美式英语) 我觉得四级收这个词有点吃饱了撑的。理由: 用Bing国际版搜automobile insurance，出来的有：Why do you need car insurance? Affordable auto insurance on and off the road. An auto is a car. (美式英语) 四级还没有阔到需要知道car的n种说法的地步吧？vehicle不更专业？倒是有本杂志叫这个：Automobile was an American automobile magazine published by the Motor Trend Group. A group of former employees of Car and Driver led by David E. Davis founded Automobile in 1986.

A car (or automobile) is a wheeled motor vehicle used for transportation. Most definitions of cars say that they run primarily on roads, seat one to eight people, have four wheels, and mainly transport people rather than goods.

汽车是一种用于运输的轮式机动车辆。大多数对汽车的定义都说，汽车主要在道路上行驶，能坐1到8个人，有四个*，主要运输人而不是货物。

Cars came into global use during the 20th century, and developed economies depend on them. The year 1886 is regarded as the birth year of the modern car when German inventor Karl Benz patented his Benz Patent-Motorwagen. Cars became widely available in the early 20th century. One of the first cars accessible to the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the US, where they replaced animal-drawn carriages and carts, but took much longer to be accepted in Western Europe and other parts of the world.

汽车在20世纪进入全球使用，发达经济体依赖汽车。1886年被认为是现代汽车的诞生之年，当时德国发明家卡尔·本茨为他的奔驰汽车专利申请了专利。汽车在20世纪初被广泛使用。大众最早接触到的汽车之一是1908年福特汽车公司生产的美国T型汽车。汽车在美国很快被采用，取代了动物拉的马车和手推车，但在西欧和世界其他地区被接受的时间要长得多。

Cars have controls for driving, parking, passenger comfort, and a variety of lights. Over the decades, additional features and controls have been added to vehicles, making them progressively more complex, but also more reliable and easier to operate. These include rear-reversing cameras, air conditioning, navigation systems, and in-car entertainment. Most cars in use in the 2010s are propelled by an internal combustion engine, fueled by the combustion of fossil fuels. Electric cars, which were invented early in the history of the car, became commercially available in the 2000s and are predicted to cost less to buy than gasoline cars before 2025.

汽车有控制驾驶、停车、乘客舒适度和各种灯光的装置。几十年来，车辆增加了额外的功能和控制，使其越来越复杂，但也更可靠，更易于操作。其中包括倒车摄像头、空调、导航系统和车内娱乐。2010年代使用的大多数汽车都是由内燃机驱动的，由化石燃料燃烧提供燃料。电动汽车是在汽车历史早期发明的，在21世纪初开始商用，预计在2025年之前购买的成本低于汽油车。

注意electric与electrical的习惯用法。电热毯、电椅、电动剃须刀用electric，强调using electrical power，或者说electrically powered.

Electrical engineering entails designing, testing and developing electrical equipment. Electrical engineers work with all types of electrical apparatus and systems: from bringing electricity into homes to designing electrical systems for aircraft. 范围广泛。

The English word car is believed to originate from Latin carrus/carrum "wheeled vehicle" or (via Old North French) Middle English carre "two-wheeled cart," both of which in turn derive from Gaulish karros "chariot." It originally referred to any wheeled horse-drawn vehicle, such as a cart, carriage, or wagon. 背chariot, cart, carriage, wagon即可。

The first working steam-powered vehicle was designed—and quite possibly built—by Ferdinand Verbiest, a Flemish member of a Jesuit mission in China around 1672. It was a 65-centimetre (26 in)-long scale-model toy for the Kangxi Emperor that was unable to carry a driver or a passenger. It is not known with certainty if Verbiest's model was successfully built or run. 第一辆蒸汽动力车是由费迪南德·韦比斯特设计的，很可能是他在1672年左右建造的。费迪南德是耶稣会驻中国使团的佛兰德成员。这是一个65厘米（26英寸）长的康熙皇帝模型玩具，无法搭载司机或乘客。目前还不确定韦比斯特的模型是否成功构建或运行。Flemish means belonging or relating to the region of Flanders in northern Europe (今比利时), or to its people, language, or culture.
