单选题{{B}}Passage 3{{/B}} Most people have had a dog or wanted one as their companion at some time in their lives. If you are thinking of buying a dog, however, you should first decide what sort of companion you need and whether the dog is likely to be happy in the surroundings you can provide. Specialists' advice is useful to help you choose the most suitable kind of dog. But in part the decision depends on common sense. Different dogs were originally developed to perform specific tasks. So, if you want a dog to protect you or your house, for example, you should choose the one that has the right size and characteristics. You must also be ready to devote a great deal of time to training the dog when it is young and give it the exercise it needs throughout its life, unless you live in the countryside and can let it run freely. Dogs are demanding pets. Cats love the house and so are satisfactory with their place where there is secure, but a dog is loyal to its master and consequently wants him to show proof of his affection. The best time to buy a baby dog is when it is between 6 and 8 weeks old so that it can transfer its love for its mother to its master. If baby dogs have not established a relationship with the human being until they are over three months old, their strong relationship will always be with dogs. They are likely to be too shy when they are brought out into the world to become good pets.

单选题How often does one hear children wishing they were grown up, and old people wishing they were young again? Each age has its pleasures and its pains, and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets. Childhood is a time when there are few responsibilities to make life difficult. If a child has good parents, he is fed, looked after and loved, whatever he may do. It is impossible that he will ever again in his life be given so much without having to do anything in return. In addition, life is always presenting new things to the child—things that have lost their interest for older people because they are too well-known. But a child has his pains: he is not so free to do what he wishes to do; he is continually being told not to do things or being punished for what he has done wrong. When the young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way that he used to as a child, he will go hungry. And if he breaks the laws of society as he used to break the laws of his parents, he may go to prison. If however, he works hard, keeps out of trouble and has good health, he can have the great happiness of building up for himself his own position in society.

单选题In what now seems like the prehistoric times of computer history, the early post-war era (战后时期), there was a quite widespread concern that computers would take over the world from man one day. Already today, less than forty years later, as computers are relieving us of more and more of the routine tasks in business and in our personal lives, we are facing with a less dramatic but also less foreseen problem. People tend to be over-trusting (过分信任) of computers and are reluctant to challenge their authority. Indeed, they behave as if they were hardly aware that wrong buttons may be pushed, or that a computer may simply malfunction (失灵). Obviously, there would be no point in investing (投入) in a computer if you had to check all its answers, but people should also rely on their own internal computers and check the machine when they have the feeling that something has gone wrong. Questioning and routine double checks must continue to be as much a part of good business as they were in pre-computer days. Maybe each computer should come with the following warning: for all the help this computer may provide, it should not be seen as a substitute for fundamental thinking and reasoning skills.

单选题Thousands of years ago, in the middle of an ocean, miles from the nearest island, an undersea volcano broke out. The hot liquid piled higher and higher and spread wider and wider. In this way, an island rose up in the sea. (15) As time went on, hot sun and cool rains made the rock split and break into pieces, sea waves dashed against the rock. In this way, soil and sand came into being. Nothing lived on the naked soil. And then the wind and birds brought plant seeds, spiders and other little creatures there. Only plants could grow first. Only in sunlight could they produce food from the minerals of the soil, water and air. While many animals landed on the island, they could find no food. A spider spun its web in vain, because there were no insects for its web to catch. Insects couldn't stay until there were plants for them to eat. So plants had to be the pioneer life on this new island.

单选题There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a "greenhouse effect" —conserving heat reflected from the earth and raising the world"s average temperature. If this view is correct and the world"s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be in water. Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth"s temperature—a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top fanning areas. Today we do not know for sure that either of these conditions will happen (though one recent government report drafted by experts in the field concluded that the greenhouse effect is very possible). Perhaps, if we are lucky enough, the two tendencies will offset each other and the world"s temperature will stay about the same as it is now.

单选题{{B}}Passage 1{{/B}} On November 19, 1863, Abraham Lincoln went to Gettysburg in Pennsylvania to speak at the National Soldiers Cemetery. The Civil War was still going on. There was much criticism of president Lincoln at the time. He was not at all popular. He had been invited to speak at Gettysburg only out of politeness. The principal speaker was to be Edward Everett, a famous statesman and speaker of the day. Everett was a handsome man and very popular everywhere. It is said that Lincoln prepared his speech on the train while going to Gettysburg. Late that night, alone in his hotel room and fired out, he again worked briefly on the speech. The next day Everett spoke fat’s. He spoke for an hour and 57 minutes. His speech was a perfect example of the rich oratory of the day. Then Lincoln rose. The crowd of 15,000 people at first paid little attention to him. He spoke for only nine minutes. At the end there was little applause. Lincoln turned to a friend and remarked, "I have failed again". On the train back to Washington, he said sadly, "That speech was a flat failure, and the people are disappointed". Some newspapers at first criticized the speech, but little by little as people redid the speech they began to understand better. (76) {{U}}They began to appreciate its simplicity and its deep meaning. It was a speech which only Abraham Lincoln could have made.{{/U}} Today, every American school child learns Lincoln's Gettysburg Address by heart. Now everyone thinks of it as one of the greatest speeches ever given in American history.
