单选题{{B}}Text 4{{/B}} According to studies cited by the National Eating Disorders Association, 42 percent of girls in first through third grade want to be thinner, 81 percent of 10-year-olds are afraid of being fat, and 51 percent of 9-and 10-year-old girls feel better about themselves if they are on a diet. In many ,ways, this fixation on weight at ever earlier ages comes at an inopportune time physiologically. At a recent Hadassah meeting at the Woodlands Community Temple in White Plains, Dr. Maxcie Schneider, the director of adolescent medicine at Greenwich Hospital, and Erica Leon, a registered dietitian, spoke about early adolescence as a time when a little bit of pudginess is necessary for proper growth, and youngsters wrestle constantly with their body image. "I can't tell you how many kids I've seen who've been on the Atkins diet, or on the South Beach diet," Ms. Leon said, adding that overweight children who try diets can be at risk of developing eating disorders. After the presentation, three mothers from Hartsdale who wanted to help their children avoid such issues spoke about how their young daughters are already beginning to become weight-conscious. Anorexia is a mental illness in which the victim eats barely enough to survive, because her distorted thinking makes her think she is fat. Bulimia, a mental illness in which someone binges on large amounts of food, then purges it through vomiting or the abuse of laxatives, is on the rise, and is surfacing in younger and younger patients, mostly girls, said Judy Scheel, the director of the Center for Eating Disorder Recovery in Mount Kisco. About 90 percent of victims of eating disorders are female, and often the male victims are on teams like wrestling and crew, where they must keep their weight low for competitive reasons. Dr. Scheel believes that where girls claim the eating disorder enables them to be thin, boys typically state their goal is to achieve or maintain a muscular but thin physique. The average onset for bulimia used to be 17, but to see teenagers age 14 and 15 with bulimia is common these days, Dr. Scheel said. Other people believe the disorders have genetic or chemical components, and many people with eating disorders respond well to anti-depressants, for example. "A certain amount of education is necessary to help young people avoid becoming obsessed with their body image. Teachers need to stay outside of talking about diets," Dr. Scheel said. "It's like a parent, always talking about their next diet. You have to help a child understand that if you cat healthily and exercise, your body is going to take care of itself." And in relatively homogenous populations, like in some Westchester schools, competition runs high. "So the young people don't really see how beautiful diversity is," she said, "and they tend to all be competing for kind of the same goals."

单选题What has happened to DOE's "solar Village on the National Mall"?

单选题SoBig. F was the more visible of the two recent waves of infection because it propagated itself by e-mail, meaning that victims noticed what was going on. SoBig. F was so effective that it caused substantial disruption even to those protected by anti-virus software. That was because so many copies of the virus spread (some 500,000 computers were infected) that many machines were overwhelmed by messages from their own anti-virus software. On top of that, one common counter-measure backfired, increasing traffic still further. Anti-virus software often bounces a warning back to the sender of an infected e-mail, saying that the e-mail in question cannot be delivered because it contains a virus. SoBig. F was able to spoof this system by "harvesting" e-mail addresses from the hard disks of infected computers. Some of these addresses were then sent infected e-mails that had been doctored to look as though they had come from other harvested addresses. The latter were thus sent warnings, even though their machines may not have been infected. Kevin Haley of Symantec, a firm that makes anti-virus software, thinks that one reason SoBig. F was so much more effective than other viruses that work this way is because it was better at searching hard drives for addresses. Brian King, of CERT, an internet-security centre at Carnegie-Mellon University in Pittsburgh, notes that, unlike its precursors, SoBig. F was capable of "multi-threading", it could send multiple e-mails simultaneously, allowing it to dispatch thousands in minutes. Blaster worked by creating a "buffer overrun in the remote procedure call". In English, that means it attacked a piece of software used by Microsoft's Windows operating system to allow one computer to control another. It did so by causing that software to use too much memory. Most worms work by exploiting weaknesses in an operating system, but whoever wrote Blaster had a particularly refined sense of humour, since the website under attack was the one from which users could obtain a program to fix the very weakness in Windows that the worm itself was exploiting. One Way to deal with a wicked worm like Blaster is to design a fairy godmother worm that goes around repairing vulnerable machines automatically. In the case of Blaster someone seems to have tried exactly that with a program called Welchi. However, according to Mr. Haley, Welchi has caused almost as many problems as Blaster itself, by overwhelming networks with "pings" signals that checked for the presence of other computers. Though both of these programs fell short of the apparent objectives of their authors, they still caused damage. For instance, they forced the shutdown of a number of computer networks, including the one used by the New York Times newsroom, and the one organising trains operated by CSX, a freight company on America's east coast. Computer scientists expect that it is only a matter of time before a truly devastating virus is unleashed.

单选题 September 11th 2001 drew the transatlantic alliance together; but the mood did not last, and over the five years since it has pulled ever further apart. A recent poll for the German Marshall Fund shows that 57% of Europeans regard American leadership in world affairs as "undesirable". The Iraq war is mainly to blame. But there is another and more. intractable reason for the growing division: God. Europeans worry that American foreign policy under George Bush is too influenced by religion. The "holy warriors" who hijacked the planes on September 11th reintroduced God into international affairs in the most dramatic of ways. It seems that George Bush is replying in kind, encouraging a clash of religions that could spell global catastrophe. Dominique Moisi, a special adviser at the French Institute for International Relations, argues that "the combination of religion and nationalism in America is frightening. We feel betrayed by God and by nationalism, which is why we are building the European Union as a barrier to religious warfare." Josef Braml, of the German Institute for International and Security Affairs, complains that in America "religious attitudes have more of an influence on political choices than in any other western democracy." The notion that America is too influenced by religion is not confined to the elites. Three in five French people and nearly as many Dutch think that Americans are too religious-and that religion skews what should be secular decisions. Europeans who think that America is "too religious" are more inclined to anti-Americanism than their fellow countrymen. 38% of Britons have an unfavourable view of America, but that number rises to 50% among people who are wary of American religiosity. Is America engaged in a faith-based foreign policy? Religion certainly exerts a growing influence on its actions in the world, but in ways more subtle and complicated than Europeans imagine. It is true that America is undergoing a religious revival. "Hot" religions such as evangelical Protestantism and hardline Catholicism are growing rapidly while "cool" mainline versions of Christianity are declining. It is also true that the Republican Party, is being reshaped by this revival. Self-identified evangelicals provided almost 40% of Mr. Bushes vote in 2004; if you add in other theological conservatives, such as Mormons and traditional Catholics, that number rises closer to 60%. All six top Republican leaders in the Senate have earned 100K ratings from the Christian Coalition. It is also true that Mr. Bush frequently uses religious rhetoric when talking of foreign affairs. On September 12th he was at it again, telling a group of conservative journalists that he sees the war on terror as "a confrontation between good and evil", and remarking, "It seems to me that there's a Third Awakening" (in other words, an outbreak of Christian evangelical fervour, of the sort that has swept across America at least twice before). And Christian America overall is taking a bigger interest in foreign policy. New voices are being heard, such as Sam Brownback, a conservative senator from Kansas who has led the fight against genocide in Darfur, and Rick Warren, the author of a bestseller called "The Purpose-Driven Life", who is sending 2,000 missionaries to Rwanda. Finally, it is true that religious figures have done some pretty outrageous things. Pat Robertson called for the assassination of Hugo Ch vez, the president of Venezuela. Lieutenant-General William "Jerry" Boykin, deputy under-secretary of defence for intelligence, toured the country telling Christian groups that radical Muslims hate America "because we're a Christian nation and the enemy is a guy named Satan". He often wore uniform.

单选题{{B}}Passage Two{{/B}} There are a number of formats for reporting research, such as articles to appear in journals, reports addressed to funding agencies, theses or dissertations as part of the requirements for university degrees, and papers to be presented at conferences. These formats differ from one another mostly in their purposes and the audiences which they address. We will now briefly describe them. The journal article is a way of reporting research for professional journals or edited collections- The research is reported in a brief, yet informative way, focusing mostly on the main features of the research such as the purpose, review of the literature (often referred to as 'background'), procedures used for carrying out the research accompanied by tables, charts, and graphs, and interpretations of the results (often referred to as 'discussion'). The content and emphasis of the journal article will vary according to the intended readers (researchers or practitioners) and it is important for the researcher to be aware of the background and interest of the readers of the journal. Articles intended to be read by practitioners will emphasize the practical implications and recommendations of the research, while articles intended to be read by researchers will describe in detail the method used to collect the data, the construction of the data collection procedures, and the techniques used for analyzing the data. It is important for the novice researcher to be aware of the fact that articles submitted to journals go through a process of evaluation by experts who make a judgement and recommend whether they should be published or not. The thesis or dissertation is a format for reporting research which graduate students write as part of fulfilling the requirements for an advanced academic degree. The student is expected to describe in great detail all the phases of the research so it can be examined and evaluated carefully by the reader. Thus the thesis or dissertation includes the purpose and significance of the study, the rationale, a thorough review of the literature, detailed information as to the research tools and the procedures involved in their development, a description of the process of data analysis and the results, and an interpretation of the results in the form of conclusions, implications, and recommendations. This detailed description of the process of the research is needed to provide the professors with an indication of the student's ability to carry out research. The conference paper is a way of reporting research at conferences, seminars, and colloquia. At such meetings research papers are usually presented orally. They are similar to the research article since research is reported in a concise, yet informative way, focusing on the most essential elements of the research. Handouts and transparencies can also accompany the presentations. As with the research article, here too, the content and emphasis of the oral report will depend to a large extent on the type of audience present at the meeting, and whether they are researchers or practitioners.

单选题He spent a large amount of money on clothes, and I guess he ______a large sum of money.

单选题I really hope that you will______your trip toCanada and get back as soon as possible.

单选题People use money to buy food, books, bicycles and hundreds of other things they need. When they work, they usually get paid in money. Most of the money used today is made of metal or paper. But in ancient times people used to use all kinds of things as money. One of the first kinds of money was shells. In China, cloth and knives were used as money. Elephant tusks, monkey tails and salt were used in some parts of Africa. Rice was also a kind of money used by the ancient people in some islands. Cows and other animals were used as money, too. The first copper coins were made in China. They were round and had a square hole in the centre. Different counties had used different metals for their money. Later some countries began to make Coins of gold and silver. But gold and silver were heavy to carry when people need a lot of coins to buy something expensive. The Chinese were the first to use paper money. The first paper money looked more like a note from one paper to another than the paper money used today.
