Part II Reading Comprehension (Skimming andScanning) (15 minutes)Directions:In this part, you will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1.For questions 1-7, choose thebest answer from the four choices marked A), B), C) and D). For questions8-10, complete the sentences with the information given in the passage. Google's Plan for World's Biggest Online Library: Philanthropy Or Act of Piracy?In recent years, teams of workers dispatched by Google have been working hard to make digital copies of books. So far, Google has scanned more than 10 million titles from libraries in America and Europe -including half a million volumes held by the Bodleian in Oxford. The exact method it uses is unclear; the company does not allow outsiders to observe the process.Why is Google undertaking such a venture? Why is it even interested in all those out-of-printlibrary books, most of which have been gathering dust on forgotten shelves for decades? Thecompany claims its motives are essentially public-spirited. Its overall mission, after all, is to "organise the world's information", so it would be odd if that information did not include books.The company likes to present itself as having lofty aspirations. "This really isn't about making money. We are doing this for the good of society." As Santiago de la Mora, head of Google Books for Europe, puts it: "By making it possible to search the millions of books that exist today, we hope to expand the frontiers of human knowledge."Dan Clancy, the chief architect of Google Books, does seem genuine in his conviction that thisis primarily a philanthropic(慈善的) exercise. "Google's core business is search and find, soobviously what helps improve Google's search engine is good for Google," he says. "But we havenever built a spreadsheet(电子数据表) outlining the financial benefits of this, and I have neverhad to justify the amount I am spending to the company's founders."It is easy, talking to Clancy and his colleagues, to be swept along by their missionary passion. But Google's book-scanning project is proving controversial. Several opponents have recently emerged, ranging from rival tech giants such asMicrosoft and Amazon to small bodies representing authors and publishers across the world. In broad terms, these opponents have levelled two sets of criticisms at Google.First, they have questioned whether the primary responsibility for digitally archiving the world's books should be allowed to fall to a commercial company. In a recent essay in the New YorkReview of Books,Robert Darnton, the head of Harvard University's library, argued that because such books are a common resource – the possession of us all – only public, not-for-profit bodiesshould be given the power to control them.The second related criticism is that Google's scanning of books is actually illegal. This allegation has led to Google becoming mired in(陷入) a legal battle whose scope and complexity makes the Jarndyce and Jarndyce case in Charles Dickens' Bleak House look straightforward.At its centre, however, is one simple issue: that of copyright. The inconvenient fact about most books, to which Google has arguably paid insufficient attention, is that they are protected by copyright. Copyright laws differ from country to country, but in general protection extends for the duration of an author's life and for a substantial period afterwards, thus allowing the author's heirs to benefit. (In Britain and America, this post-death period is 70 years.) This means, of course, that almost all of the books published in the 20th century are still under copyright –and the last century saw more books published than in all previous centuries combined. Of the roughly 40 million books in US libraries, for example, an estimated 32 million are in copyright. Of these, some 27 million are out of print.Outside the US, Google has made sure only to scan books that are out of copyright and thus in the "public domain" (works such as the Bodleian's first editionof Middlemarch,which anyone canread for free on Google Books Search).But, within the US, the company has scanned both in-copyright and out-of-copyright works. Inits defence, Google points out that it displays only small segments of books that are in copyright–arguing that such displays are "fair use". But critics allege that by making electronic copies of these books without first seeking the permission of copyright holders, Google has committed piracy."The key principle of copyright law has always been that works can be copied only once authors have expressly given their permission," says Piers Blofeld, of the Sheil Land literary agency in London. "Google has reversed this –it has simply copied all these works without bothering toask."In 2005, the Authors Guild of America, together with a group of US publishers, launched a class action suit(集团诉讼) against Google that, after more than two years of negotiation, endedwith an announcement last October that Google and the claimants had reached an out-of-courtsettlement. The full details are complicated - the text alone runs to 385 pages–and trying tosummarise it is no easy task. "Part of the problem is that it is basically incomprehensible," saysBlofeld, one of the settlement's most vocal British critics.Broadly, the deal provides a mechanism for Google to compensate authors and publishers whose rights it has breached (including giving them a share of any future revenue it generates fromtheir works). In exchange for this, the rights holders agree not to sue Google in future.This settlement hands Google the power - but only with the agreement of individual rights holders –to exploit its database of out-of-print books. It can include them in subscription deals sold to libraries or sell them individually under a consumer licence. It is these commercial provisions that are proving the settlement's most controversial aspect.Critics point out that, by giving Google the right to commercially exploit its database, thesettlement paves the way for a subtle shift in the company's role from provider of information to seller. "Google's business model has always been to provide information for free, and sell advertising on the basis of the traffic this generates," points out James Grimmelmann, associate professor at New York Law School. Now, he says, because of the settlement's provisions, Google could become a significant force in bookselling.Interest in this aspect of the settlement has focused on "orphan" works, where there is noknown copyright holder –these make up an estimated 5-10% of the books Google has scanned. Under the settlement, when no rights holders come forward and register their interest in a work, commercial control automatically reverts to Google. Google will be able to display up to 20% oforphan works for free, include them in its subscription deals to libraries and sell them to individual buyers under the consumer licence.It is by no means certain that the settlement will be enacted(执行) –it is the subject of afairness hearing in the US courts. But if it is enacted, Google will in effect be off the hook as far as copyright violations in the US are concerned. Many people are seriously concerned by this - and the company is likely to face challenges in other courts around the world.No one knows the precise use Google will make of the intellectual property it has gained byscanning the world's library books, and the truth, as Gleick, an American science writer and member of the Authors Guild, points out, is that the company probably doesn't even know itself. But what is certain is that, in some way or other, Google's entrance into digital bookselling will have a significant impact on the book world in the years to come.注意：此部分试题请在答题卡1上作答。

2011年12月英语四级真题及答案解析完整版
2011年12月英语四级真题及答案解析完整版Part I Writing【标准版】Nothing Succeeds Without a Strong WillNothing runs smoothly in our life. To achieve things successfully, a strong will is essential. Life is like a Marathon. Many people can’t get to the terminal. This is not because they are lack of vitality but because their will of success is not strong enough.To take quitting smoking as an example, some regard it as a piece of cake. They make up their minds to quit it in the morning, but in the evening they feel that the smell of cigarettes is tempting. Their throats are sore, their mouths are thirsty, and their hands are shaking. After the painful mental struggle, they tell themselves that “One cigarette is en ough. Just take one, and the next day I will quit it.” By doing this, they surrender to their weak will. In the end, they have quitted smoking “a hundred times”, but in no time they succeed.Just like quitting smoking, nothing succeeds without a strong wil l. To be successful in one’s life, a strong will means that you know where you go and you will persist on the road you choose. Undoubtedly success belongs to those who overcome their weak will and who hang in there until the last minute.【文章点评】本文属于话题类作文，只看题目“Nothing Succeeds without a strong will”考生会觉得比较抽象，难以下手。

In the autumn of 1999, he had travelled to a tourist spot to try and sell some of his paintings, when he was robbed of everything he had.With no money to return home, the heart-broken artist sheltered from the rain under a tree. An old man approached him and asked what was wrong. On hearing Zheng's reply that he felt life had no more meaning, the old man started to laugh. He picked up a leaf and said, "It all depends on how you look at TAL#NBSP it. Take this yellow leaf for example. Some may see death, others may see beauty."Zheng chose beauty and he spent the next few years perfecting his carving skills and travelling the country looking for ideas.In his technique—which Zheng successfully patented（申请专利）last year - leaves are kept slightly wet in water. He makes a simple outline on the leaf. Then comes the most difficult part - using tinny knives, Zheng gently cuts away enough of the "flesh" of the leaf to leave behind an image.Each leaf may take up to seven days to make, and Zheng says he often breaks a few for every successfully completed work. But he also says that's the real charm of it—to challenge himself.(1) In which section of a newspaper will you most probably read this article?A. ArtB. NewsC. TechnologyD. Opinion(2) What do falling leaves represent according to Zheng?A. The end of lifeB. news starting pointC. Success after struggleD.

It's not so much that we eat different things, but more that we eat different parts of the same things.Take chicken for example. Chicken feet are much prized over in China, and once these are finished, the hungry Chinese will move on to the wings and then legs, and maybe then the breast meat. In the West, the order would be exactly the opposite, except that we would never get as far as the feet, as people find the thought of it quite strange.The same can be said for pork. The Chinese consider the feet to be delicious, but in the West, things are very different. I live on a small Scottish island with my Chinese wife, and our local butcher used to throw out his pig feet, until one day my wife mentioned she would like them. She now gets a bag full every week, and smiles all the way home about the fact that she's got what she considers the best part for free.Whenever we go to the supermarket my wife is amazed that the meat without bones and fat is the most expensive. I explain that this is because western people don't see the purpose of paying for something they can't eat. But for her, these parts are the most delicious and she loves them. And happily for my wife, such bony and fat meat is also the cheapest. That's why dinner at our houses is a perfect match. There's never any argument over who gets what, and nothing goes to waste.There are also western foods the Chinese consider terrible. Take blue cheese for example, which is very popular in many western countries, but which some people think smells like rotten eggs. When my wife first saw this in the UK, she felt sick at its smell, but finally I persuade her to try it and now she loves it.It's these culture differences that make the world so full of fun.(1) What's the purpose of this passage?A. To share the author's marriage experiences with the readers.B. To prove that east-west marriage is the best.C. To argue that eating habits can never be changed.D. To discuss the cultural differences in eating habits.(2) According to the passage, in what order do westerners prefer to eat chicken?A. Breast—legs—wingsB. Legs—wings—feetC. Breast—wings—legsD. Wings—legs—breast(3) According to the passage, the author's wife.A. sometimes argues with the author about what to cookB. believes meat with fat should be the cheapestC. gets pig's feet for a very low priceD. is used to eating blue cheese now(4) The author thinks the events mentioned are very.A. interestingB. strangeC. annoyingD. boring5、【来源】 2011年广东广州高二会考（C篇）第49~52题8分Monk High School has been some amazing improvements in the past year. Students now miss fewer days and exam results have gone through the roof. But these successes are not the outcome of better teaching or stricter rules. Instead the school simply started its first lesson at 10 am instead of 9 am.The change was designed to match the school day with students' body clocks. Teenagers are well-known TAL#NBSP night-owls, preferring to stay up late and sleep till lunch time. By matching the school timetable with students' biological rhythms, the school avoids teaching teenagers when their brains are still half asleep.In the modern world, our lives are largely controlled by time. Even without watches and calendars, our bodies still follow an inner clock called body rhythms. Over each 24-hour period we experience physical and mental changes that prepare our brain and bodies for the tasks we face at different times of the day.The main controller of these rhythms is a tiny part of the brain located just above the eyes. This master clock gathers information about light and sends it to the rest of the body using electrical signals. These signals control body functions like heart beat, body temperature and more.Not surprisingly our physical and mental condition varies according to the time of the day. For example, body temperature is lowest at around 4:30 am and rises to its highest level at about 7 pm. Energy levels also rise throughout the day.These changes can affect how we perform various tasks, including athletic performance.

If you don't know where you want to go, you will never get there because there's nowhere to get to. But the other side to these bright dreams is they can be blinding. If you're blinded, you will end up in the same place: Nowhere.What you need is a balance between what is really achievable and the dreams that can give you direction but may also hold you as prisoners. Here are a few suggestions that may help you move along the path of success:Find out who you really are: Most dreams come to us at an early age. The trouble with these early dreams is that WE CHANGE. Without thinking about what you want regularly, you may be blindly following something you don't even want anymore. If you're feeling lost, or even if you're not, stop and ask yourself: What makes me happy?Don't make general goals:This is perhaps the easiest way one gets lost. Simply saying to yourself, "I want to be president" or "I want to be the next Steve Jobs" is too broad and has no plan attached. Have a clear set of goals mapped out in a weekly or monthly plan. And make sure all of those things you "could do today" are in fact done.Don't wait for something to happen to you:Simply having a strong dream will not make it come true. You create the world you live in so it's up to you to take action. If you're serious about something, know it TAL#NBSP inside and out. What are the problems? What are the opportunities? And learn from others.

12011-2012第一学期C#期末复习资料一、填空题1. .NET 框架包括 公共语言运行库 和 .NET 类库。
2. 类的成员或者是静态成员，或者是实例成员，将前者看作属于类和将后者看作属于对象很有用。
在“类”中，如果声明有多个同名的方法但它们的签名不同，则称为方法的重载。
3.在现有的类（基类）的基础上建立新类（派生类）的处理过程称为继承，这带来的好主要有代码复用、继承性多态。
可以用base 关键字从派生类中访问基类的成员。
在派生类中定义与基类同名的方法，使用new 修饰符显式隐藏从基类继承的方法成员。
4.在类声明中使用abstract 修饰符以指示类只能是其他类的基类，我们称它为抽象类；用sealed 修饰的类的特点是不能继承（密封）；virtual 关键字用于指定属性或方法可以在派生类中重写，具有该关键字的方法或属性被称作虚拟成员。
当实例方法声明包含override 修饰符时，称该方法为重写方法，重写方法用相同的签名重写继承的虚拟方法。
5. OpenFileDialog 对话框执行后，用户选择文件的文件名保存在它的FileName 属性中. 6. 如果希望在OpenFileDialog 控键中选择多个文件，应把它的MultiSelect 属性设置为true 。
7. 语句string[] Drv=Directory.GetLogicalDrives()返回系统中所有磁盘列表。
8. 试列举 中的五个主要对象Connection 、Command 、DataReader 、DataSet 、DataAdapter 。
9.C#不但具有面向对象程序语言所应有的一切特性：继承性、封装性、多态性，而且C#的一个重要创新就是使面向组件编程更加容易。
10. 借助C#，可以创建多种应用程序，如：Windows 应用程序、Web 应用程序、控制台应用程序、智能设备应用程序（Pocket PC 袖珍PC ）、移动Web 应用程序（PDA 个人数字助理）等等。
11. 每个C# 程序均必须包含一个称为Main 的方法，该过程为应用程序的起始点并为应用程序提供总体控制。
该方法在“类”的内部声明，它必须具有static 关键字，表明是静态方法。
12. 向方法传递参数有两个办法，一个是传值，另一个是传引用。
前者形参将创建新的存储位置，被调用的方法将接受参数的一个副本；后者并不创建新的存储位置，实参和形参具有相同的位置。
二、判断题1. C#代码行中，字符“//”会将这一行的其余内容转换为注释内容。
2. Main 方法是程序的入口点，程序控制在该方法中开始和结束。
3. Main 方法在类的内部声明，它必须具备有static 关键字，是静态方法。
4. Show 方法是MessageBox 类的一个静态方法。
5. 静态方法的调用一般通过在类名后加上点操作符（.）和方法名来调用它们。
6. 循环语句while 有条件执行嵌入语句零次或多次，do/while 语句有条件地执行嵌入语句一次或多次。
7. 直接基类中，除实例构造函数、静态构造函数和析构函数外，所有其它成员都被派生类继承。
8. 除了直接基类中的私有成员，所有其他继承成员都能在派生类中被存取。
9.用户界面元素，如按钮、文本框、复选框等被称为控件。
10. 代码#region 和#endregion 关键字的作用是隐藏已通过测试的代码部分。
11. 类是对象的符号表示形式，它是计算机用来创建对象的模版。
12. private 修饰符是类成员的默认修饰符。
如果移除了该修饰符，仍然会得到私有成员。
13. 在类中如果声明有多个同名的方法但它们的签名不同，则称为方法的重载。
214. 滚动条常用属性：Minimum 、Maximum 、Value 、LargeChange 、SmallChange ；常用事件Scroll 15. 用GDI+绘图需要如下步骤：创建Graphics 对象、创建笔或画笔、调用图形方法。
16. 有几种不同类型的画笔，如SolidBrush 、HatchBrush 、LinearGradientBrush 等等，所有画笔类均从Brush类继承的，该类是“抽象”类，不能实例化。
17. Timer 控件是实现在用户定义的时间间隔引发事件的计时器。
18. 不能指定接口中方法的修饰符。
答：对19. DotNet 包含两个部分，即公共语言运行时和框架类库.答案：对20. 在同一行上可以书写多条语句，每条语句间用分号分隔。

答案：错22. 在定义数组时不允许为数组中的元素赋值。
答案：错 23. 定义枚举时至少为其中的一个枚举成员赋值。
答案：错24. 接口与类同样是面向对象程序设计的核心，是创建对象的模版。
答案：对25. 委托是将方法作为参数传递给另一方法的一种数据类型。
事件与委托没有关系。
答案：错26. 如果要实现重写，在基类的方法中必须使用virtual 关键字，在派生类的方法中必须使用overrides 关键字。
答案：错27. 在C#类中，this 代表了当前类本身。
答案：错28. .静态类和实例类的区别在于：静态类不需要初始化即可直接使用，实例类需要进行实例化，生成对象才可使用。
