单选题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 window. "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 fight or the left-hand lane? After a while, of course, the excitement dies down. Sleeping for a while helps pass the middle hours of the fide. 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 tight time. There are just no more ways to sit.

单选题Adam Smith was the first person to see the importance of the division of the labor. He gave us an example of the process by which pins were made in England. One man draws out the wire, another strengthens it, a third cuts it, a fourth points it, and a fifth gives it a head. Just to make the head requires two or three different operations. The work of making pins is divided into about eighteen different operations, which in some factories are ail performed by different people, though in others the same man will sometimes perform two or three of them. Ten men, Smith said, in this way, turned out twelve pounds of pins a day or about 4,800 pins a worker. But if all of them had worked separately and independently without division of labor, they certainly could not have made twenty pins in a day and not even one. There can be no doubt that division of labor is an efficient way of organizing work. Fewer people can make more pins. Adam Smith saw this, but he also took it for granted that division of labor is itself responsible for economic growth and development and it accounts for the difference between expanding economies and those that stand still. But division of labor adds nothing new, it only enables people to produce more of what they already have.

单选题England is not a big country: from north to south and from east to west it is only about three hundred miles across. But for a small country it has a surprising range of climate. People who have never visited England, or who have visited only one part of it, often make the mistake of thinking that it is a cold and wet country. Except for the summer months of June to September, this is probably true of the north of England and the Midlands. In the south, however, the climate is much more pleasant. One result is that when people retire from a job in the north they often prefer to move down to the milder south. Perhaps the warmest part of the country is the southwest, which consists of the counties of Devon and Cornwall. The warm Gulf Stream flows across the North Atlantic Ocean from the Gulf of Mexico and makes the coastal regions of the southwest quite warm. Palm trees, bamboo (竹) and many semi-tropical (亚热带的) plants grow well in the southwest of England. Flowers and vegetables ripen (成熟) as much as a month earlier than those elsewhere. Farmers in the area obtain a higher price for their vegetables and flowers because they are ready earlier. In winter there may be several feet of snow in other parts of England but there will probably be no snow at all in the southwest. This may be one of the reasons why the southwest is one of England"s most popular holiday areas.
