单选题Following divorce, life for you and your children can be unnecessarily complicated by a variety of problems you simply hadn"t foreseen. Yet once you understand how and why your life has changed after divorce, and what you can do about it, you can gain a fresh perspective and move in the direction of improving your life. Richard Crawford was only six years old when his mother, a beautiful 32-year-old woman, first brought him to me. She claimed that Richard had "problems" adjusting to the divorce she"s acquired only five months previously. But after several sessions, she tearfully confessed that bringing Richard to see me was only an excuse to get help for herself. "I felt shy at first about telling you the truth, but I simply have to get the whole thing off my mind. Since I divorced Clive about five months ago, my life"s collapsed. I feel so depressed, lonely, rejected, and afraid of the future!" "And now you feel the divorce was a big mistake?" I asked. "Yes. But I was the one who wanted the divorce, and now I feel so miserable and depressed. I guess I"m too mixed up to think in a clear way." She replied. "It"s very common for somebody to realize gradually that life after a divorce can be more hurtful, in so many unexpected ways, than the life they endured with their former spouse(配偶). Right now things looked pretty grim and hopeless. But you"ll survive, and hopefully, start a new and better life for yourself and Richard." You should not use Richard as an excuse not to be socially active. You"ve a right to build a new life for yourself, to change your style of living to suit your new circumstances. Your self-confidence can be built up again through happy, pleasant, rewarding social experiences with new friends, new hobbies, and a new life style. Don"t let guilt feeling stand in your way. In this selection, the author mainly talked about ______.

单选题{{B}}Directions:{{/B}} There are 5 reading passages in this part. Each passage is followed by some questions or unfinished statements. Fox' each of them there are four choices marked A, B, C, and D. You should decide on the best choice and mark your answer on the ANSWER SHEET by blackening the corresponding letter in the brackets. The opposite of adaptive divergence is an interesting and fairly common expression of evolution. Whereas related groups of organisms take on widely different characters in becoming adapted to unlike environments in the case of adaptive divergence. We find that Unrelated groups of organisms exhibit adaptive convergence when they spot similar modes of life or become suited for special sorts of environments. For example, invertebrate marine animals living firmly attached to the sea bottom or to some foreign object tend to develop a sub- cylindrical or conical form. This is illustrated by coral individuals, by many sponges, and even by the diminutive tubes of bryozoans. Adaptive convergence in taking this coral-like form is shown by some brachiopods and pelecypods that grew in fixed position. More readily appreciated is the streamlined fitness of most fishes for moving swiftly through water; they have no neck, the contour of the body is smoothly curved so as to give minimum resistance, and the chief propelling organ is a powerful tail fin. The fact that some fossil reptiles (ichthyosaurs) and modem mammals (whales, dolphins) are wholly fishlike in form is an expression of adaptive convergence, for these air-breathing reptiles and mammals, which are highly efficient swimmers, are not closely related to fishes. Unrelated or distantly related organisms that develop similarity of form are sometimes designated as homeomorphs (having same form).

单选题I was only eight years old when the Second World War ended, but I can still remember something about the victory celebrations in the small town where I lived on the day when the war in Europe ended. We had not suffered much from the war there. But both at home and at school I had become accustomed to the phrases "before the war" and "when the war's over". "Before the war", apparently, things had been better, though I was too young to understand why, except that there had been no bombs then, and people had eaten things like ice -cream and bananas, which I had only heard of . When the war was over we would go back to London, but this meant little to me. I did not remember what London was like. What I remember now about VE (Victory in Europe) Day was the May evening. After dinner I said I wanted to see the bonfire (大火堆) , so when it got dark my father took me to the end of the street. The bonfire was very high, and somehow people had collected some old clothes to dress the un- mistakable figure with the moustache (胡子) they had to put on top of it. Just as we arrived, they set light to it. The flames rose and soon swallowed the "guy". Everyone was cheering and shouting, and an old woman came out of her house with two chairs and threw them on the fire to keep it going. I stood beside my father until the fire started to go down, not knowing what to say. He said nothing, either. He had fought in the First World War and may have been remembering the end of that. At last he said, "Well, that's it, son. Let's hope that this time it really will be the last one./

单选题(略){{B}}Part Ⅱ Reading Comprehension{{/B}} Few people would defend the Victorian attitude to children, but if you were a parent in those days, at least you knew where you stood: children were to be seen and not heard. Freud and company did away with all that and parents have been bewildered ever since. The child's happiness is all-important, the psychologists say, but what about the parents' happiness? Parents suffer continually from fear and guilt while their children gaily romp about pulling the place apart. A good "old-fashioned" spanking is out of the question: no modern child-rearing manual would permit such barbarity. The trouble is you are not allowed even to shout. Who knows what deep psychological wounds you might inflict? The poor child may never recover from the dreadful traumatic experience. So it is that parents bend over backwards to avoid giving their children complexes which a hundred years ago hadn't even been heard of. Certainly a child needs love, and a lot of it. But the excessive permissiveness of modern parents is surely doing more harm than good. Psychologists have succeeded in undermining parents' confidence in their own authority. And it hasn't taken children long to get wind of the fact. In addition to the great modern classics on childcare, there are countless articles in magazines and newspapers. With so much unsolicited advice flying about, mum and dad just don't know what to do any more. In the end, they do nothing at all. So, from early childhood, the kids are in charge and parents' lives are regulated according to the needs of heir offspring. When the little dears develop into teenagers, they take complete control. Lax authority over the years makes adolescent rebellion against parents all the more violent. If the young people are going to have a party, for instance, parents are asked to leave the house. Their presence merely spoils the fun. What else can the poor parents do but obey'? Children are hardy creatures (far hardier than the psychologists would have us believe) and most of them survive the harmful influence of extreme permissiveness which is the normal condition in the modern household. But a great many do not. The spread of juvenile delinquency in our own age is largely due to parental laxity. Mother, believing that little Johnny can look after himself, is not at home when he returns from school, so little Johnny roams the streets. The dividing-line between permissiveness and sheer negligence is very fine 'indeed. The psychologists have much to answer for. They should keep their mouths shut and let parents get on with the job. And if children are knocked about a little bit in the process, it may not really matter too much. At least this will help them to develop vigorous views of their own and give them something positive to react against. Perhaps there's some truth in the idea that children who have had a surfeit of happiness in their childhood appear like stodgy puddings and fail to make a success of life.

单选题Uncle Sam is a tall, thin man. He"s an older man with white hair and a white beard. He often wears a tall hat, a bow tie, and the stars and stripes of the American flag. Who is this strange, looking man? Would you believe that Uncle Sam is the US government? But why do you call the US government Uncle Sam? During the War of 1812, the US government hired meat packers to provide meat to the army. One of these meat packers was a man named Samuel Wilson. Samuel was a friendly and fair man. Everyone liked him and called him Uncle Sam. Sam Wilson stamped the boxes of meat for the army with a large US for United States. Some government inspectors came to look over Sam"s company. They asked a worker what the US on the boxes stood for. As a joke, the worker answered that these letters stood for the name of his boss, Uncle Sam. The joke spread, and soldiers began saying that their food came from Uncle Sam. Before long, people called all things that came from the government "Uncle Sam"s", "Uncle Sam" became a nickname for the US government. Soon there were drawings and cartoons of Uncle Sam in newspapers. In these early pictures, Uncle Sam was a young man. He wore stars and stripes, but his hair was dark and he had not a beard. The beard was added when Abraham Lincoln was President. President Lincoln had a beard. The most famous picture of Uncle Sam is on a poster from World War Ⅰ. The government needed men to fight in the war. In the poster, a very serious Uncle Sam points his finger and says "I want YOU for the US Army."
