单选题Electricity plays an essential part in our life. No one can deny that electric light is necessary for people"s life. However, can you imagine such a world where there is no 1 of electric light? As darkness falls over, children read in the light given by oil lamps and candies. Youths 2 time only by talking instead of watching TV. Everything is surrounded by 3 shadows. 4 , we have a man named Edison. He created bulb that 5 for two days before burning out. He also developed successfully a system for 6 electricity from a central powerhouse. It is he that gives us electric light, gramophone, moving pictures—all those we take 7 granted. After the invention of electricity, manufacturers increasingly applied the findings of invention to their businesses, 8 generating new industrial growth. Development of electricity leads to the 9 creations of new products and materials. In the past century and a half, electricity has steadily 10 . At first, it is scientific curiosity, then to a luxurious part of the 11 , and then to being necessary in every one"s life. Electricity has been common in the latest fifty years. Simple tasks, such as setting alarm clock to wake up at a 12 time or enjoying a piece of music, are accomplished via electronic means. We live with the benefits of electricity every day. As a result, we always think that whenever we 13 our gadgets into the wall socket, the power will be there. For most modern people, the loss of power means the complete loss of 14 . Their lifestyle is so dependent upon the grid"s constancy 15 they do not know how to live without it. How do you cook a meal without electricity if your gas stove has an electric ignition? Please imagine the life without electricity further. What do you do with a freezer full of food in a hot day? How do you find out what is happening in your area with the TV and radio off? These are questions which should be seriously considered. Let us imagine the 16 of a short power outage together. Factories close down; phones and computers go dead; food 17 in refrigerators. What a disordered life that would be! All the convenience which electricity has brought to our life should owe to Edison. When Edison died at has home in New Jersey in 1931, the whole United States were switched off to mark his passing, and in 18 of the man whose discoveries had so changed and improved the life of people everywhere. For a moment, all was 19 —as the world had always been before, until Edison 20 on the light.

单选题{{B}}Passage 4{{/B}} After he became Chancellor Hitler had to accept a certain degree of routine. This was against his natural inclination. He hated systematic work, hated any discipline. Administration bored him and he usually left, as much as he could to others. When he had a big speech to prepare he would put off beginning work on it until the last moment. Once he could bring himself to begin dictating he worked himself into a passion rehearsing the whole performance and shouting so loudly that his voice echoed through the neighboring rooms. The speech composed, he was a man with a load off his mind. He would invite his secretaries to lunch praising and flattering them and amusing them. Most North Germans regarded such lack of discipline as a typically Austrian characteristic. In Hitler's eyes it was part of his artist nature: he should have been a great painter or architect, he complained, and not a statesman at all. Hitler held strong views on art, and would put up with no disagreement. He passionately hated all forms of modern art. His taste was for the Classical models of Greece and Rome, and Romantic art of the nineteenth century. Gothic and renaissance Art were too Christian for his liking. He also looked on himself as highly musical, though his liking for music did not extend very much beyond the operas of Wagner, some of Beethoven and light operettas such as Lahar's Merry Widow. He was also fond of the cinema and when the Chancellery was rebuilt be had a little cinema put in, and frequently watched films in the evening, including many of the foreign films he had forbidden in Germany. He had a passion for big rooms, thick carpets and tapestries, but apart from this he had very simple tastes. He like being driven fast in a powerful car; he liked cream cakes and sweets; he liked flowers, dogs and the company of pretty—not clever women; he liked being at home in the Bavarian mountains. It was in the evenings that Hitler woke up. He hated going to bed, for he found it difficult to sleep, and after dinner he would gather his guest round the big fireplace and talk on every subject under the sun until two or three o' clock in the morning. Next morning he would not rise until eleven. Hitler ate very little, and neither smoked nor drank. He kept a special vegetarian cook but declared that eating meat or cooked meals was a bad habit that had led to the decay of past civilizations. He never touched even tea or coffee and the chief reason for his dislike of stimulants seems to have been anxiety about his health. He took little exercise and had a horror of catching a cold or any form of infection. He was depressed at the thought of dying early, before he had had time to complete his schemes, and hoped to add years to his life by careful dieting.

单选题"Opinion" is a word that is used carelessly today. It is used to refer to matters of taste, belief, and judgment. This casual use would probably cause little confusion if people didn't attach too much importance to opinion. Unfortunately, most to attach great importance to it. "I have as much right to my opinion as you to yours." and "Everyone's entitled to his opinion." are common expressions. In fact, anyone who would challenge another's opinion is likely to be branded intolerant. Is that label accurate? Is it intolerant to challenge another's opinion? It depends on what definition of opinion you have in mind. For example, you may ask a friend "What do you think of the new Ford cars?" And he may reply, "In my opinion, they're ugly." In this case, it would not only be intolerant to challenge his statement, but foolish. For it's obvious that by opinion he means his personal preference, a matter of taste. And as the old saying goes, "It's pointless to argue about matters of taste." But consider this very different use of the term, a newspaper reports that the Supreme Court has delivered its opinion in a controversial case. Obviously the justices did not shale their personal preferences; their mere likes and dislikes. They stated their considered judgment, painstakingly arrived at after thorough inquiry and deliberation. Most of what is referred to as opinion falls somewhere between these two extremes. It is not an expression of taste. Nor is it careful judgment. Yet it may contain elements of both. It is a view or belief more or less casually arrived at, with or without examining the evidence. Is everyone entitled to his opinion? Of course, this is not only permitted, but guaranteed. We are free to act on our opinions only so long as, in doing so, we do not harm others.

单选题 There are two types of people in the world. Although they have equal degrees of health and wealth and the other comforts of life, one becomes happy, the other becomes miserable. This arises from the different ways in which they consider things, persons, the events, and the resulting effects upon their minds. The people who are to be happy fix their attention on the conveniences of things, the pleasant parts of conversation, the well-prepared dishes, the goodness of the wines, and the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the contrary things. Therefore, they are continually discontented. By their remarks, they sour the pleasures of society, offend many people, and make themselves disagreeable everywhere. If this turn of mind were founded in nature, such unhappy persons would be the more to be pitied. The tendency to criticize and be disgusted is perhaps taken up originally by imitation. It grows into a habit, unknown to its possessor. The habit may be strong, but it may be cured when those who have it are convinced of its bad effects on their interests and tastes. I hope this little warming may be of service to them, and help them change this habit. Although in fact it is chiefly an act of the imagination, it has serious consequences in life, since it brings, on deep sorrow and bad luck. Those people offend many others, nobody loves them, and no one treats them with more than the most common politeness and respect, and scarcely that. This frequently puts them in bad temper and draws them into arguments. If they aim at obtaining some advantage in rank or fortune, nobody wishes them success. Nor will anyone speak a word to favor their hopes. If they bring on themselves public disapproval, not one will defend or excuse them. These people should change this bad habit. If they do not, it will be good for others to avoid any contact with them.
