Part I Reading Comprehension (2*25=50 points)Directions: There are five passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Decide on the best choice.Passage 1Children learn almost nothing from television, and the more they watch the less they remember. They regard television purely as entertainment, resent programs that demand on them and are surprised that anybody should take the medium seriously. Far from being over-excited by programs, they are mildly bored with the whole thing. These are the main conclusions from a new study of children and television. The author——Cardiac Cullingford confirms that the modern child is a dedicated viewer. The study suggests that there is little point in the later hours. More than a third of the children regularly watch their favorite programs after 9 p.m. All 11-year-olds have watched programs after midnight.Apart from the obvious waste of time involved, it seems that all this viewing has little effect. Children don’t pay close attention, says Cullingford, and they can recall few details. They can remember exactly which programs they have seen but they can rarely explain the elements of a particular plot. “Reca ll was in reverse proportion to the amount they had watched”. It is precisely because television, unlike a teacher, demands so little attention and response that children like it, argues Cullingford. Programs seeking to put over serious messages are strongly disliked. So are people who frequently talk on screen. What children like most, and remember best, are the advertisements. They see them as short programs in their own right and particularly enjoy humorous presentation. But again, they react strongly against high-pressure advertisements that attempt openly to influence them.On the other hand, they are not emotionally involved in the programs. If they admire the stars, it is because the actors lead glamorous lives and earn a lot of money, not because of their fictional skills with fast cars and shooting villains. They are perfectly clear about the functions of advertisements; by the age of 12, only one in 10 children believes what even favorite ads say about the product. And says Cullingford, educational television is probably least successful of all in imparting attitudes or information.1. The study of children and television shows that_______.A. it is useless for television companies to delay adult viewing to the later hours.B. It is a waste of time for children to watch adult programs on TV.C. Children should not watch television programs late into the night.D. Children are supposed to learn a lot from television programs.2. “Recall was in reverse proportion to the amount they had watched” (in Para.2) has almost the same meaning as________.A. “the more they watch the less they remember”. (in Para. 1)B. “Programs seeking to put over serious messages are strongly disliked”. (in Para. 2)C.“They see them as short programs in their own right”. (in Para. 2)D. “educational television is probably least successful of all in imparting attitudes or information”. (in Para. 3)3. Which of the following is NOT true according to the new study of children and television?A. Some children stay up late to watch the programs they likeB. Children enjoy watching challenging programs.C. Children don’t like serious messages and high-pressured ads.D. Though children like watching ads, most of them don't believe what ads say about the product.4. Cullingford concludes that_______.A. children are excited when they watch TV.B. Watching TV has little real effect on children.C. Parents should spend less time watching TV.D. Parents should be worried about the effect of TV on children.5. Whom would the result of the new study upset?A. The advertisers.B. The children viewers.C. The movie stars.D. The educators.Passage 2Mrs. Lester kept on asking her husband to take her to the ballet. Mr. Lester hates the ballet, but when his employers invited him and his wife, he could not get out of it. As they drove to the theatre that evening, the fog got worse and worse. The traffic slowed down to a walking pace and almost stopped. When they eventually got to the theatre, the ballet was over. Mrs. Lester could not work out how it had taken them so long to get there, even taking the fog into account. The theatre was within walking distance of their house. It took her a long time to get over the disappointment.A month later, Mrs. Lester found out what had happened. Mr. Lester told a friend of his that he had taken wrong turning on purpose. This friend told his wife, and the wife immediately went around to tell Mrs. Lester. The two women began to plan revenge. One day, when Mr. Lester was not in, they broke into his study, which he always locked. His hobby was collecting old coins. Mrs. Lester had already worked out how much his collection was worth: $850! They were taking some coins out of the case when they heard a car pull upoutside the house. Mrs. Lester quickly switched the light off, and they waited, holding their breath. The front door opened and Mr. Lester came in. They heard him take his coat off. He walked towards the study door and opened it. There was no chance for the women to get away without being seen. Mr. Lester switched the light on and was astounded to see his wife standing there with a handful of valuable coins. It took both husband and wife a long time to get over this.6. Which of the following is correct?A. Mr. Lester likes to watch ballet.B. Mrs. Lester likes to watch ballet.C. Both of them like to watch balletD. Neither of them likes to watch ballet.7. It was quite ____when they drove to the theatre.A. rainyB. stormyC. cloudyD. foggy8. The theater is _____from Mr. and Mrs. L ester’s.A. an hour-drivingB. in the other side of the cityC. very nearD. half an hour of bicycle riding9. The wife of Mr. Lester’s friend is a_____.A. social workerB. house cleanerC. baby sitterD. gossip10. How many persons are mentioned in this story?A. ThreeB. FourC. FiveD. Six.Passage 3Educating girls quite possibly yields a higher rate of return than any other investment available in the developing world. Women’s education may be unusual terri tory for economists, but enhancing women’s contribution to development is actually as much an economic as a social issue. And economics, with its emphasis on incentives, provides guideposts that point to an explanation for why so many girls are deprived of an education.Parents in low-income countries fail to invest in their daughters because they do not expect them to make an economic contribution to the family: girls grow up only to marry into somebody else’s family and bear children. Girls are thus se en as less valuable than boys and are kept at home to do housework while their brothers are sent to school-the prophecy becomes self-fulfilling, trapping women in a vicious circle of neglect.An educated mother, on the other hand, has greater earning abilities outside the home and faces an entirely different set of choices. She is likely to have fewer but healthier children and can insist on the development of all her children, ensuring that her daughters are given a fair chance. The education of her daughters then makes it much more likely that the next generation of girls, as well as of boys, will be educated and healthy. The vicious circle is thus transformed into a virtuous circle.Few will dispute that educating women has great social benefits. But it has enormous economic advantages as well. Most obviously, there is the direct effect of education on the wages of female workers. Wages rise by 10 to 20 per cent for each additional year of schooling. Such big returns are impressive by the standard of other available investments, but they are just the beginning. Educating women also has a significant impact on health practices, including family planning.11. The author argues that educating girls in developing countries is _______.A. rewardingB. troublesomeC. expensiveD. labor-saving12. By saying “... the prophecy becomes self-fulfilling...” (Para. 2), the author means that __.A. girls will eventually find their goals in life beyond reachB. girls will be increasingly discontented with their life at homeC. girls will be capable of realizing their own dreamsD. girls will turn out to be less valuable than boys13. The author believes that a vicious circle can turn into a virtuous circle when _______.A. women care more about educationB. parents can afford their daughters’ educationC. girls can gain equal access to educationD. a family has fewer but healthier children14. What does the author say about women’s education?A. It has aroused the interest of a growing number of economists.B. It will yield greater returns than other known investments.C. It is now given top priority in many developing countries.D. It deserves greater attention than other social issues.15. The passage mainly discusses _______.A. unequal treatment of boys and girls in developing countriesB. the major contributions of educated women to societyC. the economic and social benefits of educating womenD. the potential earning power of well-educated womenPassage 4David Thomson is an electronics technician, trained by the U.S. Navy, who writes instruction books for complicated equipment. He believes that every person is surrounded by a force field that can broadcast emotions to other human beings. The ability to receive such fo rce fields, Thomson believes, explains how one can sense another’s fear, nervousness, aggression, panic, or friendliness.This theory of emotional communication occurred to Thomson when he told a psychiatrist, Dr. Jack Ward, that he was certain his own hypertension made those near him uncomfortable. To demonstrate the theory, Thomson constructed a transmitter capable ofgenerating an electromagnetic field similar to that of a man beset by hyper anxiety. For a year, with this in his pocket, Thomson made people miserable. He would find a hungry man delightedly preparing to eat a steak in a restaurant, turn on the transmitter, and watch as the man became tense and irritable and finally left with his steak uneaten. In another test, Thomson cleared a crowded room in fifteen minutes. Such an exodus could not be due, Thomson observed, to personality problems alone.Dr. Ward, who had become Thomson’s partner, insisted that there was already misery enough in the world. Thomson fashioned a “happiness transmitter,” which can duplicate the force field of a contented man. University psychologists in the United States report some encouraging results in current tests of the Thomson-and-Ward transmitter.The “happiness machine” has many possibilities. Thomson has speculated on its use near disturbed or anxious patients in hospitals, and in unruly crowds. Tranquility, like panic and violence, may be contagious.16. The theory is based on belief in the existence of______.A. complicated equipmentB. individual force fieldsC. nervousnessD. aggression17. The theory occurred to Thomson because he was convinced that people near him .A. could hypnotize himB. could make him feel uncomfortableC. were reading his thoughts D were affected by his hypertension18. For his first demonstrations, Thomson chose people who____.A. were in a happy moodB. seemed hyper anxiousC. were aggressiveD. Both B and C19. The Thomson-and-Ward transmitter was constructed because____.A. university psychologists suggested itB. the “misery machine” had not workedC. Dr. Ward felt there was misery enoughD. Police forces asked for it20. Thomson has speculated on_____.A. some helpful uses of a “happiness machine”B. possi ble wrongful uses of a “happiness machine”C. the disadvantages of a tranquil populationD. the final report on the psychologists’ testsPassage 5Does a bee know what is going on in its mind when it navigates its way to distant food sources and back to the hive, using polarized sunlight and the tiny magnet it carries as a navigational aid? Or is the bee just a machine, unable to do its mathematics and dance its language in any other way? To use Dondald Griffin’s term, does a bee have “awareness”, or to use a phrase I like better, can a bee think and imagine?There is an experiment for this, or at least an observation, made long ago by Karl von Firsch and more recently confirmed by James Gould in Princeton. Biologists who wish to study such things as bee navigation, language, and behavior in general have to train their bees to fly from the hive to one or another special place. To do this, they begin by placing a source of sugar very close to the hive so that the bees (considered by their trainers to be very dumb beasts) can learn what the game is about. Then, at regular interval, the dish or whatever is moved progressively farther and farther from the hive, in increments of about 25 percent at each move. Eventually, the target is being moved 100 feet or more at a jump, very far from the hive. Sooner or later, while this process is going on, the biologist shifting the dish of sugar will find the bees are out there waiting for them, precisely where the next position had been planned. This is an uncomfortable observation to make.21. The best title for the passage is_____A. Teaching the Bees to NavigateB. Testing the Awareness of BeesC. Navigational Techniques of BeesD. Behaviorists Versus Biologists: A Zoological Debate22. The word “awareness” in Paragrap h One appears in quotation marks in order to ____A. show the author’s preference for the termB. indicate that it is being used humorouslyC. acknowledge Donald Griffin’s previous use of the termD. point out that it was used differently earlier in the passage23. In the second paragraph Karl von Frisch is mentionedA. to introduce his observation on bee behaviorB. to contrast his theories with those of James GouldC. acknowledge Donald Griffin’s previous use of the termD. point out that it was used differently earlier in the passage24. According to the author, sugar was used in the study______A. to reward the bees for performing the experiment correctlyB. to train the bees to travel to a particular placeC. to ensure that the bees knew where the hive wasD. to ensure that the bees would obey the orders25. The result of the experiment explained in the passage seems to indicate that______A. research using bees is too dangerous to be conducted successfullyB. bees are unable to navigate beyond 100 feet their hiveC. scientists can teach bees to navigateD. bees are able to perform limited reasoning tasksPart II Vocabulary and Structure (0.5*40=20 points)Directions: There are 40 incomplete sentences in this part.

新版山东科技大学数学考研经验考研真题考研参考书

在决定考研的那一刻,我已预料到这一年将是怎样的一年,我做好了全身心地准备和精力来应对这一年枯燥、乏味、重复、单调的机械式生活。

可是虽然如此,我实在是一个有血有肉的人呐,面对诱惑和惰性,甚至几次妥协,妥协之后又陷入对自己深深的自责愧疚当中。

这种情绪反反复复,曾几度崩溃。

所以在此想要跟各位讲,心态方面要调整好,不要像我一样使自己陷入极端的情绪当中,这样无论是对自己正常生活还是考研复习都是非常不利的。

所以我想把这一年的经历写下来,用以告慰我在去年饱受折磨的心脏和躯体。

告诉它们今年我终于拿到了心仪学校的录取通知书,你们的付出和忍耐也终于可以扬眉了。

知道自己成功上岸的那一刻心情是极度开心的,所有心酸泪水,一扫而空,只剩下满心欢喜和对未来的向往。

首先非常想对大家讲的是,大家选择考研的这个决定实在是太正确了。

非常鼓励大家做这个决定,手握通知书,对未来充满着信念的现在的我尤其这样认为。

当然不是说除了考研就没有了别的出路。

只不过个人感觉考研这条路走的比较方便,流程也比较清晰。

没有太大的不稳定性,顶多是考上,考不上的问题。

而考得上考不上这个主观能动性太强了,就是说,自己决定自己的前途。

所以下面便是我这一年来积攒的所有干货,希望可以对大家有一点点小小的帮助。

由于想讲的实在比较多,所以篇幅较长,希望大家可以耐心看完。

文章结尾会附上我自己的学习资料,大家可以自取。
