填空题Computer science is not only a comparatively young field, but also one that has had to prove it is really science. Skeptics in academia would often say that after Alan Turing described the concept of the" universal machine" in the late 1930's—he idea that a computer in theory could be made to do the work of any kind of calculating machine, including the human brain—all that remained to be clone was mere engineering. The more generous perspective today is that decades of stunningly rapid advances in processing speed, storage and networking, along with the development of increasingly clever software, have brought computing into science, business and culture in ways that were barely imagined years ago. The quantitative changes delivered through smart engineering opened the door to qualitative changes. Computing changes what can be seen, simulated and done. So in science, computing makes it possible to simulate climate change and unravel the human genome (基因组). In business, low-cost computing, the Internet and digital communications are transforming the global economy. In culture, the artifacts of computing include the iPod and computer-animated movies. What's next? That was the subject of a symposium (研讨会)in Washington held by the Computer Science and Telecommunications Board. Joseph F. Traub, the board's chairman and a professor at Columbia University, titled the symposium "2016". Computer scientists from academia and companies like IBM and Google discussed topics including social networks, digital imaging, online media and the impact on work and employment. But most talks touched on two broad themes: the impact of computing will go deeper into the sciences and spread more into the social sciences, and policy issues will loom large, as the technology becomes more powerful and more pervasive. Social networks are pre-technological creations that sociologists have been analyzing for decades. However with the rise of the Internet, social networks and technology networks are becoming inextricably linked, so that behavior in social networks can be tracked on a scale never before possible. The new social-and-technology networks that can be studied include e-mail patterns, buying recommendations on commercial Web sites like Amazon, messages and postings on community sites like My Space and Face book, and the diffusion of news, opinions, fids, urban myths, products and services over the Internet. Social net- working research promises a rich trove (珍藏品) for marketers and politicians, as well as sociologists, economists, anthropologists, psychologists and educators.

填空题For investors who desire low risk and guaranteed income, U. S. government bonds are a secure investment because these bonds have the financial backing and full faith and credit of the federal government. Municipal bonds, also secure, are offered by local governments and often have 31 such as tax-free interest. Some may even be 32 Corporate bonds are a bit more risky. Two questions often 33 first-time corporate bond investors. The first is "If I purchase a corporate bond, do I have to hold it until the maturity date?" The answer is no. Bonds are bought and sold daily on 34 securities exchanges. However, if you decide to sell your bond before its maturity date, you"re not guaranteed to get the face value of the bond. For example, if your bond does not have 35 that make it attractive to other investors, you may be forced to sell your bond at a 36 , i. e. , a price less than the bond"s face value. But if your bond is highly valued by other investors, you may be able to sell it at a premium, i.e. , a price above its face value. Bond prices generally 37 inversely(相反地)with current market interest rates. As interest rates go up, bond prices fall, and vice versa(反之亦然). Thus, like all investments, bonds have a degree of risk. The second question is "How can I 38 the investment risk of a particular bond issue?" Standard & Poor"s and Moody"s Investors Service rate the level of risk of many corporate and go vernment bonds. And 39 , the higher the market risk of a bond, the higher the interest rate. Investors will invest in a bond considered risky only if the 40 return is high enough. A. advantages B. assess C. bother D. conserved E. deduction F. discount G. embarrass H. features I. fluctuate J. indefinite K. insured L. major M. naturally N. potential O. simultaneously

填空题To Americans, the goal of parents is to help children stand on their own two feet. From 31 , each child may get his or her own room. As children grow, they gain more 32 to make their own choices. Teenagers choose their own forms of 33 , as well as the friends to share them with. When they reach young adulthood, they choose their own careers and marriage partners. The relationship between parents and children in America is very informal. American parents try to treat their children as individuals—not as 34 of themselves. They allow them to 35 their own dreams. Americans praise and encourage their children to give them the confidence to succeed. When children become adults, their relationship with their parents becomes more like a friendship among equals. But 36 adults, they respect and honor their parents. Disciplining children is another area that American parents have differing opinions about. Many parents feel that an old-fashioned spanking helps youngsters learn what "No!" means. Others prefer 37 forms of discipline. For example, "time outs" have become popular in recent years. Children in "time out" have to sit 38 or by a wall. They can get up only when they are ready to act nicely. Older children and teenagers who 39 may be grounded, or not allowed to go out with friends. Being a parent is a tall order. It takes patience, love, 40 , courage and a good sense of humor to raise children.

填空题Americans no longer expect public figures, whether in speech or in writing, to command the English language with skill and gift. Nor do they aspire to such command themselves. In his latest book, Doing Our Own Thing: The Degradation of Language and Music and Why We Should, Like, Care, John Mcwhorter, a linguist and controversialist of mixed liberal and conservative views, sees the triumph of 1960s counter culture as responsible for the decline of formal English. Blaming the permissive 1960s is nothing new, but this is not yet another criticism against the decline in education. Mr. Mcwhorter's academic speciality is language history and change, and he sees the gradual disappearance of "whom", for example, to be natural and no more regrettable than the loss of the case endings(词格)of Old English. But the cult of the authentic and the personal, "doing our own thing", has spelt the death of formal speech, writing, poetry and music. While even the modestly educated sought an elevated tone when they put pen to paper before the 1960s, even the most well regarded writing since then has sought to capture spoken English on the page. Equally, in poetry, the highly personal, performative genre is the only form that could claim real liveliness. In both oral and written English, talking is triumphing over speaking, spontaneity(自然发生) over craft. Illustrated with an entertaining array of examples from both high and low culture, the trend that Mr. Mcwhorter documents is unmistakable. But it is less clear, to take the question of his subtitle, why we should, like, care. As a linguist, he acknowledges that all varieties of human language, including non-standard ones like Black English, can be powerfully expressive—there exists no language or dialect in the world that cannot convey complex ideas. He is not arguing, as many do, that we can no longer think straight because we do not talk proper. Russians have a deep love for their own language and carry chunks of memorized poetry in their heads, while Italian politicians tend to elaborate speech that would seem old fashioned to most English speakers. Mr. Mcwhorter acknowledges that formal language is not strictly necessary, and proposes no radical educational reforms—he is really grieving over the loss of something beautiful more than useful. We now take our English "on paper plates instead of china". A shame, perhaps, but probably an inevitable one.
