单选题 Mathematical ability and musical ability may not seem on the surface to be connected, but people who have researched the subject and studied the brain say that they are. Three quarters of the bright but speech-delayed children in the group I studied had a close relative who was an engineer, mathematician or scientist, and four fifths had a close relative who played a musical instrument. The children themselves usually took readily to math and other analytical subjects and to music. Black, white and Asian children in this group show the same patterns. However, it is clear that blacks have been greatly overrepresented in the development of American popular music and greatly underrepresented in such fields as mathematics, science and engineering. If the abilities required in analytical fields and in music are so closely related, how can there be this great discrepancy? One reason is that the development of mathematical and other such abilities requires years of formal schooling, while certain musical talents can be developed with little or no formal training, as has happened with a number of well-known black musicians. It is precisely in those kinds of music where one can acquire great skill without formal training that blacks have excelled popular music rather than classical music, piano rather than violin, blues rather than opera. This is readily understandable, given that most blacks, for most of American history, have not had either the money or the leisure for long years of formal study in music. Blacks have not merely held their own in American popular music. They have played a disproportionately large role in the development of jazz, both traditional and modern. A long string of names comes to mind—Duke Ellington, Scott Joplin, W.C. Handy, Louis Armstrong, Charlie Parker...and so on. None of this indicates any special innate ability of blacks in music. On the contrary, it is perfectly consistent with blacks having no more such inborn ability than anyone else, but being limited to being able to express such ability in narrower channels than others who have had the money, the time and the formal education to spread out over a wider range of music, as well as into mathematics, science and engineering.

单选题Did Sarah Josepha Hale write 'Mary's Little Lamb,' the eternal nursery rhyme (儿歌) about a girl named Mary with a stubborn lamb? This is still disputed, but it's clear that the woman 27 for writing it was one of America's most fascinating 28 . In honor of the poem's publication on May 24, 1830, here's more about the 29 author's life. Hale wasn't just a writer, she was also a 30 social advocate, and she was particularly 31 with an ideal New England, which she associated with abundant Thanksgiving meals that she claimed had 'a deep moral influence.' She began a nationwide 32 to have a national holiday declared that would bring families together while celebrating the 33 festivals. In 1863, after 17 years of advocacy including letters to five presidents, Hale got it. President Abraham Lincoln, during the Civil War, issued a 34 setting aside the last Thursday in November for the holiday. The true authorship of 'Mary's Little Lamb' is disputed. According to the New England Historical Society, Hale wrote only part of the poem, but claimed authorship. Regardless of the author, it seems that the poem was 35 by a real event. When young Mary Sawyer was followed to school by a lamb in 1816, it caused some problems. A bystander named John Roulstone wrote a poem about the event, then, at some point, Hale herself seems to have helped write it. However, if a 1916 piece by her great-niece is to be trusted, Hale claimed for the 36 of her life that 'some other people pretended that someone else wrote the poem'. A. campaign B. career C. characters D. features E. fierce F. inspired G. latter H. obsessed I. proclamation J. rectified K. reputed L. rest M. supposed N. traditional O. versatile

单选题It seems that the writer is very critical of ______.

单选题 It is all very well to blame traffic jams, the cost of petrol and the quick pace of modern life, but manners on the roads are becoming horrible. You might tolerate the rude and inconsiderate driver, but nowadays the well-mannered motorist is the exception to the rule. Perhaps the situation calls for a 'Be Kind to Other Drivers' campaign, otherwise, it may get completely out of hand. Road politeness is not only good manners, but also good sense. It takes the most cool-headed and good-tempered drivers to resist the temptation to revenge when subjected to uncivilized behaviors. On the other hand, a little politeness goes a long way towards relieving the tensions of motoring. A friendly nod or a wave of acknowledgement in response to an act of politeness helps to create an atmosphere of good will and tolerance so necessary in modern traffic conditions. But such acknowledgements of politeness are all too rare today. Many drivers nowadays don't even seem able to recognize politeness when they see it. However, improper politeness can also be dangerous. A typical example is the driver who waves a child across a crossing into the path of oncoming vehicles that may be unable to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they care to. A veteran driver, whose manners are faultless, told me it would help if motorists learned to filter correctly into traffic streams one at a time without causing the total blockages that would give rise to bad temper. Unfortunately, modern motorists can't even learn to drive, let alone be well-mannered on the road. Years ago the experts warned us that the car-ownership explosion would demand a lot more give-and-take from all road users. It is high time for all of us to take this message to heart.

单选题 Seven Steps to a More Fulfilling Job A. Many people today find themselves in unfulfilling work situations. In fact, one in four workers is dissatisfied with their current job, according to the recent 'Plans for 2004' survey. Their career path may be financially rewarding, but it doesn't meet their emotional, social or creative needs. They're stuck, unhappy, and have no idea what to do about it, except move to another job. B. Mary Lyn Miller, veteran career consultant and founder of the Life and Career Clinic, says that when most people are unhappy about their work, their first thought is to get a different job. Instead, Miller suggests looking at the possibility of a different life. Through her book, 8 Myths of Making a Living, as well as workshops, seminars and personal coaching and consulting, she has helped thousands of dissatisfied workers reassess life and work. C. Like the way of Zen, which includes understanding of oneself as one really is, Miller encourages job seekers and those dissatisfied with work or life to examine their beliefs about work and recognize that 'in many cases your beliefs are what brought you to where you are today.' You may have been raised to think that women were best at nurturing and caring and, therefore, should be teachers and nurses. So that's what you did. Or, perhaps you were brought up to believe that you should do what your father did, so you have taken over the family business, or become a dentist 'just like dad.' If this sounds familiar, it's probably time to look at the new possibilities for your future. D. Miller developed a 7-step process to help potential job seekers assess their current situation and beliefs, identify their real passion, and start on a journey that allows them to pursue their passion through work. Step 1: Willingness to do something different. E. Breaking the cycle of doing what you have always done is one of the most difficult tasks for job seekers. Many find it difficult to steer away from a career path or make a change, even if it doesn't feel right. Miller urges job seekers to open their minds to other possibilities beyond what they are currently doing. Step 2: Commitment to being who you are, not who or what someone wants you to be. F. Look at the gifts and talents you have and make a commitment to pursue those things that you love most. If you love the social aspects of your job, but are stuck inside an office or 'chained to your desk' most of the time, vow to follow your instinct and investigate alternative careers and work that allow you more time to interact with others. Dawn worked as a manager for a large retail clothing store for several years. Though she had advanced within the company, she felt frustrated and longed to be involved with nature and the outdoors. She decided to go to school nights and weekends to pursue her true passion by earning her master's degree in forestry. She now works in the biotech forestry division of a major paper company. Step 3: Self-definition. G. Miller suggests that once job seekers know who they are, they need to know how to sell themselves. 'In the job market, you are a product. And just like a product, you most know the features and benefits that you have to offer a potential client, or employer.' Examine the skills and knowledge that you have, and identify how they can apply to your desired occupation. Your qualities will exhibit to employers why they should hire you over other candidates. Step 4: Attain a level of self-honoring. H. Self-honoring or self-love may seem like an odd step for job hunters, but being able to accept yourself, without judgment, helps eliminate insecurities and will make you more self-assured. By accepting who you are—all your emotions, hopes and dreams, your personality, and your unique way of being—you'll project more confidence when networking and talking with potential employers. The power of self-honoring can help to break all the falsehoods you were programmed to believe—those that made you feel that you were not good enough, or strong enough, or intelligent enough to do what you truly desire. Step 5: Vision. I. Miller suggests that job seekers develop a vision that embraces the answer to 'What do I really want to do?' one should create a solid statement in a dozen or so sentences that describe in detail how they see their life related to work. For instance, the secretary who longs to be an actress describes a life that allows her to express her love of Shakespeare on stage. A real estate agent, attracted to his current job because her loves fixing up old homes, describes buying properties that need a little tender loving care to make them more saleable. Step 6: Appropriate risk. J. Some philosophers believe that the way to enlightenment comes through facing obstacles and difficulties. Once people discover their passion, many are too scared to do anything about it. Instead, they do nothing. With this step, job seekers should assess what they are willing to give up, or risk, in pursuit of their dream. For one working morn, that meant taking night classes to learn new computer-aided design skills, while still earning a salary and keeping her day job. For someone else, it may mean quitting his or her job, taking out loan and going back to school full time. You'll move one step closer to your ideal work life if you identify how much risk you are willing to take and the sacrifices you are willing to make. Step 7: Action. K. Some teachers of philosophy describe action in this way, 'If one wants to get to the top of a mountain, just sitting at the foot thinking about it will not bring one there. It is by making the effort of climbing up the mountain, step by step, that eventually the summit is reached.' All too often, it is the lack of action that ultimately holds people back from attaining their ideals. Creating a plan and taking it one step at a time can lead to new and different job opportunities. Job-hunting tasks gain added meaning as you sense their importance in your quest for a more meaningful work life. The plan can include researching industries and occupations, talking to people who are in your desired area of work, taking classes, or accepting volunteer work in your targeted field. L. Each of these steps will lead you on a journey to a happier and more rewarding work life. After all, it is the journey, not the destination that is most important.

单选题The question of whether war is inevitable is one which has concerned many of the world's great writers. Before considering this question, it will be useful to introduce some related concepts. Conflict, defined as opposition among social entities directed against one another, is distinguished from competition, defined as opposition among social entities independently striving for something which is in inadequate supply. Competitors may not be aware of one another, while the parties to a conflict are. Conflict and competition are both categories of opposition, which has been defined as a process by which social entities function in the disservice, of one another. Opposition is thus contrasted with cooperation, the process by which social entities function in the service of one another. These definitions are necessary because it is important to emphasize that competition between individuals or groups is inevitable in a world of limited resources, but conflict is not conflict; nevertheless, is very likely to occur, and is probably ,an essential and desirable element of human societies. Many authors have argued for the inevitability of war from the premise that in the struggle for existence among animal species, only the fittest survive. In general, however, this struggle in nature is competition, not conflict. Social animals, such as monkeys and cattle, fight to win or maintain leadership of the group. The struggle for existence occurs not in such fights, but in the competition for limited feeding areas and for the occupancy of areas free from meat-eating animals. Those who fail in this competition starve to death or become victims to other species. This struggle for existence does not resemble human war, but rather the competition of individuals for jobs, markets, and materials. The essence of the struggle is the competition for the necessities of life that are insufficient to satisfy all. Among nations there is competition in developing resources, trades, skills, and a satisfactory way of life. The successful nations grow and prosper; the unsuccessful decline. While it is true that this competition may induce efforts to expand territory at the expense of others, and thus lead to conflict, it cannot be said that war-like conflict among nations is inevitable, although competition is.
