【简答题】
Taking the train is a wonderful way to see America. In the 19th century, train routes appeared from coast to coast, carrying both people and goods Today, a long-distance Amtrak train trip is a different way to experience the United States. The long-distance Amtrak trains have lots of room. Coach seats have lots of leg room and wide aisles(走廊),sightseeing lounges(休闲室) have large windows, and sleeping areas can provide a good night’s rest. On a train trip, there’s time to talk, play cards or board games, and read to one another. On a car trip, parents have to drive while on a train, parents can sit back and watch the scenery go by. Unlike an airplane, traveling by train is not the quickest way to arrive at your destination; the train is the destination in itself. Amtrak manages long-distance trains that run through the United States. Routes have different names, such as Empire Builder, California Zephyr, Sunset Limited and Southwest Chief. The long-distance trains have double-decker cars(Superliners), sightseeing lounges, and a real dining car. On shorter trains, such as from New York to Washington. DC, the cars are single level and only have a snack bar. In the Superliner trains, the sightseeing lounge is lined with windows on the second level while on the lower level a snack bar and tables can be found. In the evening, videos are shown in the lounge car—either entertaining movies or documentaries. Tip: As delays are common on Amtrak trains, always call the station before you go there. Otherwise, you may be cooling your heels( 脚后跟 ) for hours . 小题1:What’s the advantage of seeing America by train?
