Stricken with polio（小儿麻痹症）as a child，Perlman 41 walked with the aid of two crutches（拐杖）to a chair in the middle of the stageHe carefully laid the crutches on the floor, _42 one leg forward and the other underneath his chair, picked up his instrument and nodded to the 43 to begin.But something went wrong. After only seconds of playing, one of the strings on his violin 44 .The audience immediately knew what happened and fully expected the concert to be 45 until another string or even another instrument could be found. But Perlman 46 them. He quickly calmed down, closed his eyes and then 47 the conductor to begin again. So the orchestra played from where they had 48 and Perlman played on three strings. He played 49 passion and power. All the time he worked out new fingering in his mind to make up for the 50 string. A work that few people 51 play well on four strings, Perlman accomplished on three. When he finished, a（n） 52 silence hung in the roomAnd then as one， the crowd rose to their feet and 53 wildly. Applause burst forth from every corner of the auditorium 54 fans showed deep 55 for his talent and his courage. Perlman smiled and wiped the sweat from his forehead. Then he raised his bow to 56 the crowd and said， not proudly, but in a 57 , quiet, holy tone, “You know, sometimes it is the artists 58 to find out how much music you can still make with what you have left.”Such was Itzhak Perlman, a great violinist. Playing a concert on three strings is not unlike his philosophy of life he 59 what he had left and still made music.

The copied material, which has the same genetic makeup as the original, is referred to as a clone.How are genes cloned?Researchers routinely use cloning techniques to make copies of genes that they wish to study. The procedure consists of inserting a gene from one organism, often referred to as foreign DNA, into the genetic material of a carrier called a vector(带菌者). Examples of vectors include bacteria, yeast cells or viruses. After the gene is inserted, the vector is placed in laboratory conditions that prompt it to multiply, resulting in the gene being copied many times over.What animals have been cloned?Over the last 50 years, scientists have conducted cloning experiments in a wide range of animals using a variety of techniques. In 1979, researchers produced the first genetically identical mice by splitting mouse embryos in the test tube and then implanting the resulting embryos into the wombs of adult female mice. It was not until 1996, however, that researchers succeeded in cloning the first mammal from a mature cell taken from an adult animal. After 276 attempts, Scottish researchers finally produced Dolly, the lamb from the udder cell of a 6-year-old sheep. Besides, other mammals that have been cloned include: cat, deer, dog, horse, mule, ox, rabbit and rat.Have humans been cloned?Despite several highly publicized claims, human cloning still appears to be fiction. There currently is no solid scientific evidence that anyone has cloned human embryos.In 1998, scientists in South Korea claimed to have successfully cloned a human embryo, but said the experiment was interrupted very early when the clone was just a group of four cells.In 2004, a group led by Woo-Suk Hwang of Seoul National University in South Korea published a paper in the journalSciencein which it claimed to have created a cloned human embryo in a test tube. However, an independent scientific committee later found no proof to support the claim and, in January 2006,Scienceannounced that Hwangs paper had been retracted(撤销).Why is human cloning difficult? From a technical perspective, cloning humans and other primates（灵长类动物） is more difficult than in other mammals. One reason is that two proteins essential to cell division are located very close to the chromosomes（染色体） in primate eggs. Consequently, removal of the eggs nucleus to make room for the donor nucleus also removes the proteins, interfering with cell division. In other mammals, such as cats, rabbits and mice, the two proteins are spread throughout the egg. So, removal of the eggs nucleus does not result in loss of proteins. In addition, some dyes and the ultraviolet light used to remove the eggs nucleus can damage the primate cell and prevent it from growing.What are some of the ethical issues related to cloning?Cloning would present the potential of creating a human that is genetically identical to another person who has previously existed or who still exists. This may conflict with long-standing religious and societal values about human dignity, possibly violating principles of individual freedom, identity and autonomy（自主权）. However, some argue that cloning could help sterile(生育困难的) couples fulfill their dream of parenthood. Others see human cloning as a way to avoid passing on a hurtful gene that runs in the family without having to undergo embryo screening or embryo selection.61. Why did Science retract Hwangs paper? A. Hwang copied others finds in his paper. B. Science found out mistakes in the paper. C. There was no proof to support Hwangs claim.D. Hwang wanted to update the paper by adding new things.62. Which of the following statements about cloning is true? A. The cloning procedure consists of inserting a vector into the genetic material. B. Dolly was successfully cloned after a few attempts. C. There is no possibility that sterile couples can give birth to their babies.D. Removal of the eggs nucleus can contribute to the failure of human cloning. 63. What is the main purpose of the selection? A. To challenge new findings in the paper. B. To report the latest discoveries of cloning. C. To claim new possibilities of cloning.D. To provide information about cloning. BPicture a wasteland of old computer monitors and TVs, stretching as far as the eye can see. Imagine towers of boxes, all of them filled with broken glass and discarded electronic devices. Technology graveyards like this can be found in communities across the country.Experts say that landfills and warehouses will overflow unless a plan for the disposal (清理)and reuse of electronics is put into place .” We cant put electronics and glass aside and tell ourselves well deal with them later,” Lauren Roman, managing director of Transparent Planet said. Romans group works to improve the disposal of electronic waste. She says about 660 million pounds of tech trash is produced each year in the U.S.Whats behind the tech trash pile-up? About ten years ago, major advances were made in computer and television technology. Manufacturers began producing devices like flat paneled LCDs and plasma(等离子) screen monitors. These new products provide a clearer image and take up less space than older models. It goes without saying that consumers choose them rather than heavy. Glass-based technologies.The new electronics are built with materials that are difficult to recycle. In addition, the new products have decreased the demand for recycled parts from the older monitors and screens. Older, heavier computer monitors and TVs used glass-based components called CRTs.CRTs have a high lead content and can be environmentally hazardous if not recycled properly. If crushed and put in landfills, the lead from CUTs could seep into groundwater and rivers, harming the water supply. For many years, plants and recycling programs safely processed CRTs. The recycled CRTs were reused in the construction of new monitors.Monitors being made today do not use glass tubes. “People are returning old style TVs with CRTs, but no new ones are being made,” said Linnell. This is creating an imbalance in the amount of glass being disposed of and recycled properly. Many recycling companies have shut down. Others no longer have the resources or space to process these materials. This results in stockpiling.However, experts say there are ways to safely and responsibly address the tech-trash problem.64What is the main idea of the passage?AExperts are trying to solve the tech-trash problem.BNew technology causes trouble for recyclers.CNew technology has both advantages and disadvantages.DCRTs from old computer monitors and TVs harm the earth.65. What Lauren Roman says in Paragraph 2 shows that .Afiguring out how to deal with electronic waste is urgentBpeople attach great importance to electronic wasteChe has found a new way on how to dispose electronic wasteDmore landfills are needed for storing electronics and glass66We learn from Paragraph 3 that flat-paneled plasmas and LEDs .Aproduce wastes which are less harmfulBare using heavy , grass-based technologies.Care putting heavy, glass-based technologies out of the marketDare very easy for recyclers to recycle for reuseCAbout this time every year, I get very nostalgic(怀旧的). Walking through my neighborhood on a fall afternoon reminds me of a time not too long ago when sounds of children filled the air, children playing games on a hill, and throwing leaves around in the street below. I was one of those children, carefree and happy. I live on a street that is only one block long. I have lived on the same street for sixteen years. I love my street. One side has six houses on it, and the other has only two houses, with a small hill in the middle and a huge cottonwood tree on one end. When I think of home, I think of my street. Only I see it as it was before. Unfortunately things change. One day, not long ago, I looked around and saw how different everything has become. Life on my street will never be the same because neighbors are quickly grown old, friends are growing up and leaving, and the city is planning to destroy my precious hill and sell the property to contractors. It is hard for me to accept that many of my wonderful neighbors are growing old and wont be around much longer. I have fond memories of the couple across the street, who sat together on their porch swing almost every evening, the widow next door who yelled at my brother and me for being too loud, and the crazy old man in a black suit who drove an old car. In contrast to those people, the people I see today are very old neighbors who have seen better days. The man in the black suit says he wants to die, and another neighbor just sold his house and moved into a nursing home. The lady who used to yell at us is too tired to bother any more, and the couple across the street rarely go out to their front porch these days. It is difficult to watch these precious people as they near the end of their lives because at once I thought they would live forever. The “comings and goings” of the younger generation of my street are now mostly “goings” as friends and peers move on. Once upon a time, my life and the lives of my peers revolved around home. The boundary of our world was the gutter at the end of the street. We got pleasure from playing night games or from a breathtaking ride on a tricycle. Things are different now, as my friends become adults and move on. Children who rode tricycles now drive cars. The kids who once played with me now have new interests and values as they go their separate ways. Some have gone away to college like me, a few got married, two went into the army, and one went to prison. Watching all these people grow up and go away makes me long for the good old days. Perhaps the biggest change on my street is the fact that the city is going to turn my precious hill into several lots for now homes. For sixteen years, the view out of my kitchen window has been a view of that hill. The hill was a fundamental part of my childhood life; it was the hub of social activity for the children of my street. We spent hours there building forts, sledding, and playing tag. The view out of my kitchen window now is very different; it is one of tractors and dump trucks tearing up the hill. When the hill goes, the neighborhood will not be the same. It is a piece of my childhood. It is a visual reminder of being a kid. Without the hill, my street will be just another pea in the pod.There was a time when my street was my world, and I thought my world would never change. But something happened. People grow up, and people grow old. Places changes, and with the change comes the heartache of knowing I can never go back to the times I loved. In a year or so, I will be gone just like many of my neighbors. I will always look back to my years as a child, but the place I remember will not be the silent street whose peace is interrupted by the sounds of construction. It will be the happy, noisy, somewhat strange, but wonderful street I knew as a child.67. The writer finds it hard to accept the fact that _.

The Big Changes of My StreetDHigh-quality customer service is preached (宣扬) by many, but actually keeping customers happy is easier said than done.Shoppers seldom complain to the manager or owner of a retail store, but instead will alert their friends, relatives, co-workers, strangersand anyone who will listen.Store managers are often the last to hear complaints, and often find out only when their regular customers decide to frequent their competitors, according to a study jointly conducted by Verde Group and Wharton School.“Storytelling hurts retailers and entertains consumers,” said Paula Courtney, President of the Verde Group. “The store loses the customer, but the shopper must also find a replacement.”On average, every unhappy customer will complain to at least four others, and will no longer visit the specific store. For every dissatisfied customer, a store will lose up to three more due to negative review. The resulting “snowball effect” can be disastrous to retailers.According to the research, shoppers who purchased clothing encountered the most problems. Ranked second and third were grocery and electronics customers.The most common complaints include filled parking lots, cluttered (塞满了的) shelves, overloaded racks, out-of-stock items, long check-out lines, and rude salespeople.During peak shopping hours, some retailers solved parking problems by getting moonlighting (业余兼职的) local police to work as parking attendants. Some hired flag wavers to direct customers to empty parking spaces. This guidance eliminated the need for customers to circle the parking lot endlessly, and avoided confrontation between those eyeing the same parking space.Retailers can relieve the headaches by redesigning store layouts, pre-stocking sales items, hiring speedy and experienced cashiers, and having sales representatives on ha
