Write ONE WORD for each answer.II. Grammar and Vocabulary (26分)Section ADirections: After reading the passages below, fill in the blanks to make the passages coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.(A)Many kinds of music can stir the imagination and produce strong feeling. For some people, romantic composers such as Chopin and Tchaikovsky enhance feelings of love and sympathy. Religious and spiritual music 25 help some people feel peace or lessen their pain. But one musician seems to have a unique ability of healing(治愈) the human body – Wolfgang Amadeus Mozart. Scientists have found Mozart’s music to be remarkable in its abil ity 26 (calm) its listeners. It can also increase their perceptions, and help them express themselves more clearly.Many amazing cases have been documented using Mozart 27 a healing aid. For example, a tiny premature baby 28 (name) Krissy, who weighed just 1.5 pounds at birth, was on total life support. Doctors thought she had little chance of survival. Her mother insisted on playing Mozart for Krissy, and thought 29 saved her daughter’s life. Krissy lived, 30 she was very small for her age and slower than the average child. At the age of four, she showeda n i n t e r e s t i n m u s i c a n d h e r p a r e n t s g a v e h e r v i o l i n l e s s o n s.31 their astonishment, Krissy was able to play musical pieces from memory that were far beyond the ability of an average four-year-old. 32 (play) music helped her improve in all areas of her life.(B)Touch is the first tool we turn to when we face pain. We react similarly to 33 injured toe and a broken heart, tenderly 34 (grasp) the affected area. We are all born with the power to heal ourselves and to heal others because healing energy does not come from within but from outside ourselves. The energy is there for anyone to use, and no formal training 35 (require). When you have the intent to heal, and love is your only motive, you become a channel for healing energy. Through the simple touch of hands, you can use that universal healing energy to comfort those who 36 (experience) pain or distress.In performing healing energy work, it is necessary that you let your intuition (直觉) guide you to the affected area. Just imagine a healing light being drawn in through the top of your head and flowing through your hands. The energy will begin to flow once you have made a physical connection, and your touch will help awaken the body’s capacity for self-healing. The affected areas of the body, 37 were previously tense or tight, will relax with enough healing energy.38 (try) not to feel like you aren’t helping if you don’t feel the flow. The work you ar e doing is indeed helping.Understanding 39 energy works is less important than consciously making use of it. Performing a loving healing treatment on your loved ones can be a wonderful experience that brings you closer together. And as the healing energy passes through you, it can awaken a feeling within you that helps you 40 (well) understand the interactions between the spiritual, physical and mental selves.Section BDirections:Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.Genes are found in every plant or animal cell. They are the basic units of life that are capable of passing specific 41 from one generation to another. For example, whether you are tall or short depends upon the genes that you 42 from your parents. Cloning plants or animals is a process that 43 the production of a new organism that is genetically identical to the organism from which cells were taken. Although this 44 has aroused great interest around the world over the last ten years or so, cloning is not something new in nature. Most mothers give birth to just one child at a time; however, on rare 45 a mother may give birth to a set of twins. If these two children are identical twins, then they are in fact naturally 46 clones of each other, although not of the parents. The reason for them being clones is that the two children originated from one 47 egg and consequently they are genetically identical. Twins thatd e v e l o p f r o m t w o48 eggs are not clones of each other.Cloning also occurs naturally in plants. Strawberry plants reproduce themselves by sending out runners, or modified stems, and these runners take root a short distance from the 49 plant and start to grow, and to produce fruit. In time, this plant sends out runners of its own that also take root. This is known as asexual reproduction; in other words, reproduction that does noti n v o l v e t h e f u s i o n(融合)o f m a l e a n d f e m a l e c e l l s.T h e n e w l y50 plants are clones of the original. In addition to strawberry plants, certain types of flowers and grasses reproduce themselves in the same way. Throughout history, people have also facilitated cloning by taking small cuttings from plants and then growing them into new plants. This form of cloning is called vegetative propagation.III. Reading Comprehension(47分)Section ADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.Robert Frank, an economist at Cornell, believes that his profession is restricting cooperation and generosity. In the U.S., economics professors give __51__ money to charity than professors in other fields. Economics students in Germany are more likely than those from other majors to recommend an overpriced plumber (水管工) when they are __52__ to do it. Economics majors tend to rate __53__ as “generally good,” “correct,” and “moral” more than their peers.Does studying economics change people? Maybe not. It could be self-selection: students who already believe in self-interest are __54__ to economics. But this doesn't exclude the possibility that studying economics pushes people further toward the selfish extreme. By spending time with like-minded people, economics students may become __55__ that selfishness is widespread and reasonable -- or at least that giving is rare and foolish.“As a business school professor, these effects worry me, as economics, __56__ every aspect of our lives, is taught widely in business schools, providing a __57__ for courses in management, finance, and accounting.” says Frank.If economics can __58__ pro-social behavior, which is central to the well-being of people or society, what should we do about it? A change in economics and business __59__ is suggested. Courses in behavioral economics, which considers the role of “social preferences” like __60__, fairness and cooperation, are required for students of economics major. In fact, economics courses not involving some behavioral economics are considered both an inadequate education and a poorpreparation to be a practising economist. Also, __61__ width, economics majors are required to take courses in social sciences like sociology and psychology, which place considerable emphasis on how people are __62__ about others, not only themselves. __63__, within economics courses, we should do a better job __64__ the principle of self-interest, which involves anything a person values -- including helping others.Not until then may the prophecy (预言) by Nobel Prize-winning economist and philosopher Amartya Sen be __65__. Calling economists “rational fools,” he observed: “The purely economic man is indeed close to being a social fool.”51. A. fewer B. less C. smaller D. more52.

For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)I used to think of myself as a fairly cosmopolitan(全球的)sort of person, but my bookshelves told a different story as my literature collection mainly consisted of British and American titles. Worse still, I hardly ever read anything in translation. My reading was limited to stories by English-speaking authors.So, at the start of 2012, I set myself the challenge of trying to read a book from every country in a year to find out what I was missing.With no idea how to go about this, thinking that I was unlikely to find books from nearly 200 nations from my local bookshop, I decided to ask the planet’s readers for help. I created a blog called A Year of Reading the World, appealing for suggestions of titles that I could read in English.The response was amazing. Before I knew it, people all over the world were getting in touch with ideas and offers of help. Some posted me books from their home countries. Others did hours of research on my behalf. In addition, several writers sent me unpublished translations of their novels, giving me a rare opportunity to read works otherwise unavailable to the 62% of British people who only speak English. Even with such support, however, sourcing books was no easy task.Tracking down stories in some unfamiliar places even took as much time as the reading and blogging. It was hard to fit it all in around work and many were the nights when I sat bleary-eyed (睡眼惺忪的) into the small hours to make sure I stuck to my target of reading one book every 1.87 days.Still,one by one, the country names on the list made at the start of the year transformed into vital, exciting places filled with laughter, love, anger, hope and fear. Lands that had once seemed exotic became familiar to me – places I could identify with. At its best, I learned, fiction makes the world real.66.What help did the writer receive to achieve his goal?A.Some writers sent him their original works.B.The local bookstore provided books from 200 nations even if it was unlikely.C.Some writers did research work on what books are popular.D.Some people mailed books from their own countries.67.In order to accomplish his goal, the writer did the following except ______.A.asking for help from all over the worldB.making full use of his leisure time after workC.reading until early next morningD.appealing to writers to send him new books68.What does the word "exotic" in the last paragraph most probably mean?A.Unrealistic.B. Uncivilized.C. Strange.D. Unimaginable.69.Which of the following best describe the writer’s experience in the year?A. Original but tiringB. Hard but relaxingC. Busy but fruitfulD.

As is known,it is always the case in some of the scariest sciencefiction.Now, science fiction has changed into sciencefact. For the first time, researchers have created arobotic machine that can stand a beating and keep onwalking. Developed by scientists from CornellUniversity and the University of Vermont, the newrobot looks like a spider with four legs. Until now, even the most advanced robot was almost certain to break down when damaged. That’sbecause its inside computer simply doesn’t know how to operate the machine aft er its shape has changed.To get around this problem, the spidery robot’s developers equipped their invention with eight motors and two sensors that read how the machine is tilting(倾斜). The motors and sensors all provide electrical signals to the machine ’s software.Using this information, the system follows a new procedure to figure out the machine’s shape at any given moment. The program chooses from among 100,000 possible arrangements of parts. From there, the computer considers a wide variety of possible next steps, and it calculates how best to move the robot forward the longest possible distance, before trying to move again. “The new strategy is a major advance in robotics”, Professor Skehan, a scientist in Cornell University says, “and it’s far from scary”. The technology may someday help researchers create better artificial arms and legs that give new freedom to people who lack them. The new knowledge might also help scientists understand how people and animals figure out their own sense of place in space.“Designing robots that can adapt to changing environments and can compensate (补偿) for damage has been a difficult problem,” says neuroscientist Olaf Sporns of Indiana University in Bloomington. “This work provides a new way toward solving this important problem.”74. What’s the most important characteristic of the new robot?A. Its shape is like a spider with four legs.B. It can repair itself and move again after damaged.C. It is operated by its inside computer.D. It is certain to change the direction when damaged.75. it can be learnt from the passage that ________.A. animals have no sense of place in spaceB. people have difficulty in figuring out how to get to his destinationC. scientists don ’t understand people ’s ability of locationD. scientists want to know where people and animals are going76. We can infer from the view of Professor Skehan that ________.A. the new technology will help people have a better sense of spaceB. the new technology will help people grow new arms and legsC. designing robots can help to be adaptable to the changing of the environmentD. the new technology will have some medical benefits77. The purpose of the author to write this article is to ________.A. introduce a new robot that will not dieB. discuss science fiction and new inventionC. recommend the latest inventionD. explain the relationship between robot and medicineSection CDirections: Read the passage carefully. Then answer the questions or complete the statements in NO MORE THAN TEN WORDS.With 26 British prime ministers, 58 Nobel prize winners, over 150 Olympic medals and a "notable alumni" list that reads like a historical hall of fame, the institutions of Oxford and Cambridge – collectively known as Oxbridge – are seen, by many, as the dream alma mater(母校).However, as admission season dawns, and the October 15 deadline for Oxbridge inches ever closer, many students may wonder what makes the UK's top two institutions so special. Why does Oxbridge symbolize the academic dream for so many? Do the universities deserve the reputation they hold in the minds of so many teenagers, parents and academics?There is no doubt that both Oxford and Cambridge have a long standing history of academia. Yet, what is often overlooked is the strong reputation of countless other universities in the UK.A simple click on Google can tell students that the London School of Economics and Political Sciences, for example, has over 18 Nobel Prize winners and 50 world leaders. University College London attracts students from 150 countries and has exchange and research links with nearly 300 overseas universities. Manchester University has the largest student union of all UK universities and boasts alumni such as Niels Bohr and James Chadwick.I suddenly realized the Oxbridge effect when I was out in London with friends. I met some new people and was surprised by their reaction when I told them I was going to study at Cambridge. One person even got down on one knee and kissed my hand.From then on, I told people I was going on a gap year. Although I knew that Oxbridge provides a good education, I had never expected to get such extreme reactions. It was this that made me start to feel uncomfortable about the way that Oxbridge is viewed.The Cambridge Tab, the university's student newspaper, has argued that what makes Cambridge special is the fact that the students are told that they are unique and a cut above the rest, so they believe it. Ron Weasley never took the Felix Felicis potion that Harry Potter pretended to give him – all he had to do to win the Quidditch match was to believe he was great.For students applying now, yes, you will receive a world class education at Oxbridge, but you will find the same at numerous other universities throughout the country. Every time you hearabout the brilliance of Oxbridge, consider that just because many believe, it does not have to be so.78. The examples of the London School of Economics and Political Sciences, University College London and Manchester University serve to illustrate the point that __________________________________in the UK.79.
