单选题We all associate colors with feelings and attitudes. In politics, dark blue often means "tradition", and red means "social change". But blue can also mean sadness (I'm feeling blue). White is often for purity, although in China white is worn for funerals, and red is used to express the joy of a wedding, in western Europe white is worn at weddings and black for funerals. Advertisers are aware of the importance of selecting colors according to the way people react to them. Soap powders come in white and light blue packets ( clean and cold, like ice); cereals often come in brown packets (tike wheat fields), but cosmetics never come in brown jars (dirty). Where do these ideas come from? Max Luscher from the University of Geneva believes that in the beginning life was dictated by two factors beyond our control: night and day. Night brought passivity, and a general slowing down of metabolism; day brought with it the possibility of action, and increased in the metabolic rate, thus providing us with energy and initiative. Dark blue, therefore, is the color of quietness and passivity, bright yellow the color of hope and activity. In prehistoric times, activity as a rule took one of two forms: either we were hunting and at- tacking, or we were being hunted and defending ourselves against attack. Attack is universally re- presented by the color red; serf-preservation by its complement green.

单选题There are many commonly held beliefs about eyeglasses and eyesight that are not proven facts. For instance, some people believe that wearing glasses too soon weakens the eyes. But there is no evidence to show that the structure of eyes is changed by wearing glasses at a young age. Wearing the wrong glasses, however, can prove harmful. Studies show that for adults there is no danger, but children can develop loss of vision if they have the wrong glasses. We have all heard some of the common myths about how eyesight gets bad. Most people believe that reading in dim light causes pool eyesight, but that is unique. Too little light makes the eyes work harder, so they do get tired and strained. Eyestrain also results from reading a lot, reading in bed, and watching too much television. But, although eyestrain may cause some pain or headaches, it does not permanently damage eyesight. Another myth about eyes is that they can be replaced, or transferred from one person to another. There are close to one million nerve fibers that connect the eyeball to the brain, and as if yet it is impossible to attach them all in a new person. Only certain parts of the eye—the cornea and the retina-can be replaced. But if we keep clearing up the myths and learning more about the eyes, someday a full transplant may be possible!

单选题Entrepreneurs are everybody's darlings these days. They may be small, but they are innovative. And innovation, we are assured, is the main engine of economic growth. For policymakers everywhere, the task is to get the little critters to nest and breed. Give them the conditions they like--plenty of venture capital, tax breaks and a risk-taking culture—and the sun will shine on all of us, just like in California. Along comes Amar Bhide to tell us most of this is plain wrong. Entrepreneurs, he asserts, are not risk-takers at all. Nor do most of them innovate, or depend on venture capital. His findings are striking enough. Start with his assertion that entrepreneurs are not innovators or risk-takers. The vast majority of new businesses, he points out, start small and stay that way. These are the hairdressing salons, corner shops and landscape gardeners. Those are mature, predictable industries. For just that reason, they are the least profitable. The success stories come in areas of high uncertainty, where markets are changing fast because of technology, regulation or fashion. A very large proportion, unsurprisingly, are in computing. But Mr. Bhide insists they are rarely innovative. The people who start high-growth businesses take a humdrum idea, usually from someone else, then change it constantly to fit the market. The starting point is much less important than what happens next. Nor are they risk-takers. These are typically young people, with no money, expertise or status. They have nothing to lose. Risk arrives later on, when they have made their pile and must decide whether to invest in long-term growth or sell out. This is one reason why so few promising start-ups become a Dell or Microsoft. Taking planned, calculated risks is the job of big, established companies, Mr. Bhide argues. True entrepreneurs rarely have the temperament for it. What they have, instead, is a high tolerance for ambiguity--defined as knowledge that you know you do not have. Few of Mr. Bhide's interviewees began with any kind of business plan. That would have been a waste of time: the future was simply too uncertain. Therein lay their opportunity. Big companies may be happy with risk, but they cannot stand ambiguity. They can invest billions in a chip plant or oil field, but only when they know the odds. When the odds are unknown, entrepreneurs have the game to themselves.

单选题Do you know how to use a mobile phone without being rude to the people around you? Talking during a performance irritates(激怒)people. If you are expecting an emergency call, sit near the exit doors and set your phone to vibrate(振动). When your mobile phone vibrates, you can leave quietly and let the others enjoy the performance. Think twice before using mobile phones in elevators, museums, churches or other indoor public places — especially enclosed spaces. Would you want to listen to someone's conversation in these places? Worse yet, how would you feel if a mobile phone rang suddenly during a funeral? It happens more often than you think. Avoid these embarrassing situations by making sure your mobile phone is switched off. When eating at a restaurant with friends, don't place your mobile phone on the table. This conveys the message that your phone calls are more important than those around you. Mobile phones have sensitive microphones that allow you to speak at the volume you would on a regular phone. This enables you to speak quietly so that others won't hear the details of your conversation. If you are calling in a noisy area, use your hand to direct your voice into the microphone.
