美国是个在轮子上的国家。大多数美国人都拥有汽车，有的甚至为之而着迷。他们会花大量时间讨论究竟要买进口车还是国产车，确定哪一款车是最好的家用车或最好的跑车。汽车修理也是个大众话题。你可以参与(他们的)讨论，谈你(拥有)的汽车或与人共享你从汽车杂志上看到的信息

America is a nation on wheels. Most Americans are car owners and some are even obsessive about the subject. They can spend hours discussing whether to buy a foreign car or an American car, and deciding on the best family car or the best sports car. Car repair is also a popular topic. You can participate in their discussion by talking about cars you have owned or by sharing information you’ve read in automotive magazines such as Car and Driver or Popular Mechanics.
