     Long bus rides are like television shows. They have a beginning, a middle, and an end with commercials

(商业广告) 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 (广告牌) glides (滑行) by outside the bus window.

"Buy Super Clean Toothpaste." "Drink Good Wet Root Beer." "Fill up with Pacific Gas." Only if you sleep,

which is equal to turning the television 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

(鲁莽的) or daring, the ride can be as thrilling (惊险的) as a suspense (悬念) story. Will the driver pass the

truck in time? Will the driver move into the right or the left hand lane (车道)? After 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 arm rests even with

your hands crossed behind your head. The end comes just at no more ways to sit.
