单选题{{B}}Passage Three{{/B}} Successful business tends to continue implementing the ideas that made them successful. But in a rapidly changing world, ideas often become obsolete overnight. What worked in the past won't necessarily work in the future. In order to thrive in the future, you must constantly create new ideas for every aspect of your business. In fact, you must continually generate new ideas just to keep your head above water. Businesses that aren't creative about their future may not survive. Although Bill Gates is the richest, most successful man on the planet, he did not anticipate the Internet. Now he's scrambling to catch up. If Bill Gates can miss a major aspect of his industry, it can happen to you in your industry. Your business needs to continually innovate and create its future. Gates is now constantly worried about the future of Microsoft. Here's what he said in a recent interview in U.S. News World Report: "Will we be replaced tomorrow? No. In a very short time frame, Microsoft is an incredibly strong company. But when you look to the two to three-year time frame, I don't think anyone can say with a straight face that any technology company has a guaranteed position. Not Intel, not Microsoft, not Compaq, not Dell, take any of your favorites. And that's totally honest. " You may remember that in 1985 the Cabbage Patch Kids dolls were the best-selling toy on the market. But after Coleco Industries introduced their sensational line of dolls they became complacent and didn't create any new toys worth mentioning. As a result, Coleco went bankrupt in 1988. The most successful businesses survive in the long term because they constantly reassess their situations and reinvest themselves accordingly. The 3M Company has a 15% rule: Employees are encouraged to spend 15% of their time developing new ideas on any project they desire. It's no surprise, then, that 3M has been around since 1902. Most businesses are not willing to tear apart last year's model of success and build a new one. Here's a familiar analogy to explain why they are lulled into complacency; imagine that your business is like a pot of lobsters. To cook lobsters, you put them into a pot of warm water and gradually turn up the heat. The lobsters don't realize they're being cooked because the process is so gradual. As a result, they become complacent and die without a struggle. However, if you throw a lobster into the pot when the water is boiling, it will desperately try to escape. This lobster is not lulled by a slowly changing environment. It realizes instantly that it's in a bad environment and takes immediate action to change its status.

单选题To us it seems so natural to put up an umbrella to keep the water off when it rains. But actually the umbrella was not invented as protection against rain. Its first use was as a shade against the sun. Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, way back in the eleventh century B.C. We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honor and authority. In the Far East in ancient times, the umbrella was allowed to be used only by royalty or by those in high offices. In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was in common use in ancient Greece. But it is believed that the first persons in Europe to use the umbrella as protection against rain were the ancient Romans. During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared again in Italy in the late sixteenth century. And again it was considered a symbol of power and authority. By 1680, the umbrella appeared in France and later on in England. By the eighteenth century, the umbrella was used against rain throughout most of Europe. Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasn"t until the twentieth century that women"s umbrellas began to be made in a whole variety of colors.
