阅读理解 Long bus rides are like television shows. They have a beginning, a middle, and an end—with commercials thrown in every three or four minutes. The commercials are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard glides by outside the bus win-dow. "Buy Super Clean Toothpaste. "" Drink Root Beer. " "Fill up with Pacific Gas. " Only if you sleep, which is equal to turning the television set off, are you spared the unending cry of "You Need It! Buy It Now.! " The beginning of the ride is comfortable and somewhat exciting, even if you' ve traveled that way before. Usually some things have changed--new houses, new buildings, sometimes even a new road. The bus driver has a style of driving and it' s fun to try to figure it out the first hour or so. If the driver is particularly reckless or daring, the ride can be as thrilling as a suspense story. Will the driver pass the truck in time? Will the driver move into the right or the left-hand lane? Af-ter a while, of course, the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But you' ve got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops. The end of the ride is somewhat like the beginning. You know it will soon be over and there ' s a kind of expectation and excitement in that. The seat, of course, has become harder as the hours have passed. By now you' ve sat with your legs crossed, with your hands in your lap, with your hands on the armrests--even with your hands crossed behind your head. The end comes just at the right time. There are just no more ways to sit.

【正确答案】 A

【答案解析】推理判断题。这篇文章的结构比较清楚，作者就是讲述自己对长途公交车旅途(开始、途中、结尾)的感受，这和A一致。作者并没有表露出说服大家乘坐长途公交车的意思，所以B不对。作者只是说长途公交旅途像电视节目，并没说明两者的不同，C也不对。第一段描述了路边的广告牌，但不是全文的主要内容，D太片面。
