Text 3People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a similar problem. They often accept the opinions or ideas of other people. Other times they begin to act without thinking; they try to find a solution by trial and error. However, when all these methods fail, the person with a problem has to start analyzing. There are six stages in analyzing a problem.First the person must recognize that there is a problem. For example, Sam’ s bicycle is broken, and he cannot ride it to class as he usually does. Sam must see that there is a problem with his bicycle.Next the thinker must define tile problem. Before Sam can repair his bicycle, he must find the reason why it does not work. For instance, he must determine if the problem is with the gears, the brakes, or the frame. He must make his problem more specific.Now the person must look for information that will make the problem clearer and lead to possible solutions. For in stance, suppose Sam decided that his bike does not work because there is something wrong with the gear wheels. At this time, he can look in his bicycle repair book and read about gears. He can talk to his friends at the bike shop. He can look at his gears carefully.After studying the problem, the person should have several suggestions for a possible solution.Take Sam as an illustration. His suggestions might be: put oil on the gear wheels; buy new gear wheels and replace the old ones; tighten or loosen the gear wheels.Eventually one suggestion seems to be the solution to the problem. Sometimes the final idea comes very suddenly because the thinker suddenly sees something new or sees something in a new way. Sam, for example, suddenly sees that there is a piece of chewing gum between the gear wheels. He immediately realizes the solution to his problem: he must clean the gear wheels.Finally the solution is tested. Sam cleans the gear wheels and finds that afterwards his bicycle works perfectly. In short, he has solved the problem. What is the best title for this passage（）
Text 2According to psychologists, an emotion is aroused when a man or animal views something as either bad or good. When a person feels like running away from something he thinks will hurt him, we call this emotion fear. If the person wants to re move the danger by attacking it, we call the emotion anger. The emotions of joy and love are aroused when we think some thing can help us. An emotion does not have to be created by something in the outside world. It can be created by a per son’s thoughts.Everyone has emotions. Many psychologists believe that infants are born without emotions. They believe children learn emotions just as they learn to read and write. A growing child not only learns his emotions but learns how to act in certain situations because of an emotion.Psychologists think that there are two types of emotions: positive and negative. Positive emotions include love, liking, joy, delight, and hope. They are aroused by something that appeals to a person. Negative emotions make a person unhappy or dissatisfied. They include anger, fear, despair, sadness, and disgust. In growing up, a person learns to cope with the negative emotions in order to be happy.Emotions may be weak or strong. Some strong emotions are so unpleasant that a person will try any means to escape from them. In order to feel happy, the person may choose unusual ways to avoid the emotion.Strong emotions can make it hard to think and to solve problems. They may prevent a person from learning or paying attention to what he is doing. For example, a student taking an examination may be so worried about failing that he cannot think properly. The worry drains valuable mental energy he needs for the examination. The author's purpose of writing this passage is to （）
Text 4Admittedly, minor accidents and slip ups continue to shake public confidence in nuclear power.Given the unquantifiable risks that nuclear power carries, it is only right that the industry be subjected to the test of public opinion and due political process. However, this argues for exceptional vigilance, regulatory scrutiny and accountability-and not for bans or shutdowns.Those nuclear operators with a good safety record deserve to have their licenses renewed, so that existing plants may run to the end of their useful lives.The Bush administrations enthusiastic support goes a lot further than this, however. It also wants to see new plants. Proponents of new nuclear power stations make three arguments in their favor.They will enhance energy security by lessening dependence on fossil fuels; Far from being environmentally harmful, they will be beneficial because they will reduce the output of greenhouse gases; And, most crucially, the economics of nuclear power has improved from the days when it was wholly dependent on bail out and subsidy.Yet these arguments do not stand up to scrutiny. The claim that governments should support nuclear power to reduce their vulnerability to the OPEC oil cartel is doubly absurd. Little oil is used in power generation: what nuclear power displaces is mostly natural gas and coal, which are not only more plentiful than oil but also geographically better distributed. Security is enhanced not by seeking energy self - sufficiency but through diversification of supplies. Creating lots of fissile material that might be pinched by terrorists is an odd way to look for security anyway. What about the argument that climate change might be the great savior of nuclear power Global warming is indeed a risk that should be taken more seriously than the Bosh administration has so far done.Nuclear plants do not produce any carbon dioxide, which is the principal greenhouse gas.However, rushing in response to build dozens of new nuclear plants would be both needlessly expensive and environ mentally unsound. It would make far more sense to adopt a carbon tax, which would put clean energy sources such as solar and wind on an equal footing with nuclear, whose waste poses an undeniable (if remote) environmental threat of its own for aeons to come.Governments should also dismantle all subsidies on fossil fuels--especially for coal, the dirtiest of all. They should adopt reforms that send proper price signals to those who use power, and so reduce emissions. Global warming certainly pro vides one argument in favor of nuclear power: But it is not sufficient on its own to justify a nuclear renaissance. The most important reason wily the Bush administration support more new nuclear power plants is that（）
