Answers to Selected Problems

解决问题的秘诀的英文作文Title: The Secret to Problem Solving。

Problem-solving is an essential skill that we all need in various aspects of life. Whether it's overcoming personal challenges, tackling complex issues at work, or finding solutions to global problems, the ability to effectively solve problems is invaluable. So, what is the secret to successful problem-solving?First and foremost, problem-solving requires a clear understanding of the issue at hand. Before diving into finding solutions, it's crucial to define the problem accurately. This involves breaking down the problem intoits essential components, identifying any underlying causes or factors contributing to it, and understanding the context in which it exists. Without a thorough understanding of the problem, any attempts at finding a solution are likely to be ineffective or even counterproductive.Once the problem is clearly defined, the next step isto generate possible solutions. This often involves brainstorming ideas, thinking creatively, and considering various perspectives. It's essential to explore a widerange of options, even those that may seem unconventionalor unlikely at first glance. Sometimes, the most innovative solutions arise from thinking outside the box.After generating a list of potential solutions, thenext step is to evaluate each one critically. This involves assessing the feasibility, effectiveness, and potential consequences of each solution. It's essential to weigh the pros and cons carefully and consider how each option aligns with the desired outcome. Additionally, seeking input from others can provide valuable insights and perspectives that may not have been considered initially.Once the options have been evaluated, the mostpromising solution can be selected and implemented. However, the process doesn't end there. Problem-solving is often an iterative process, and it's essential to monitor theimplementation of the chosen solution closely. This involves tracking progress, gathering feedback, and making adjustments as needed. Flexibility and adaptability are key qualities in successful problem-solving, as unexpected challenges or obstacles may arise along the way.Another crucial aspect of effective problem-solving is collaboration. Rarely do we solve problems in isolation, and working with others can lead to more robust solutions. Collaboration allows for the pooling of diverse skills, knowledge, and perspectives, leading to more comprehensive problem-solving outcomes. Additionally, involving stakeholders in the problem-solving process fosters buy-in and support for the chosen solution.Furthermore, maintaining a positive attitude and mindset is essential for successful problem-solving. Challenges and setbacks are inevitable, but approaching them with optimism, resilience, and determination can make all the difference. Instead of viewing obstacles as insurmountable barriers, see them as opportunities for growth and learning. Embracing a solution-focused mindsetempowers us to overcome adversity and find creative ways to address even the most daunting problems.In conclusion, the secret to successful problem-solving lies in a combination of factors: understanding the problem, generating innovative solutions, critically evaluating options, implementing the chosen solution, collaboratingwith others, and maintaining a positive mindset. Byfollowing these principles and approaches, we can navigate challenges effectively and achieve meaningful outcomes in both our personal and professional lives.。

《计算机导论》(第2版)习题答案参考计算机导论(第2版)习题答案参考Chapter 1: Introduction to Computers1. Define a computer and discuss its attributes.A computer is an electronic device capable of performing various operations and processes based on a set of instructions. Its attributes include the ability to input, process, store, and output information, as well as the capability to execute complex calculations and perform tasks.2. Differentiate between hardware and software.Hardware refers to the physical components of a computer system, including the central processing unit (CPU), memory, storage devices, input/output devices, and peripherals. Software, on the other hand, represents the non-tangible parts of a computer system, such as programs and data that can be stored and executed by the hardware.3. Explain the concept of data representation and discuss different numbering systems used in computer systems.Data representation refers to the way data is stored and processed by a computer. Different numbering systems include the binary system (base-2), decimal system (base-10), octal system (base-8), and hexadecimal system (base-16). Each system has its own set of symbols and rules for representing numbers and characters.Chapter 2: Computer Hardware1. Discuss the major components of a computer system.A computer system consists of several major components, including the central processing unit (CPU), memory, storage devices, input/output devices, and peripherals. The CPU is responsible for executing instructions and performing calculations, while memory stores data and instructions temporarily. Storage devices are used for long-term data storage, andinput/output devices allow users to interact with the computer system.2. Describe the functions and characteristics of the CPU.The CPU is the central processing unit of a computer system and is responsible for executing instructions and performing calculations. It consists of two main components: the control unit, which manages the execution of instructions, and the arithmetic logic unit (ALU), which performs calculations and logical operations. The CPU's performance is determined by factors such as clock speed, cache size, and number of cores.3. Explain the different types of memory in a computer system.A computer system typically has two main types of memory: primary memory (RAM) and secondary memory (storage devices). RAM, or random access memory, is used for temporary data storage and is volatile, meaning its contents are lost when the power is turned off. Secondary memory, such as hard disk drives and solid-state drives, provides long-term storage for data even when the power is off.Chapter 3: Operating Systems1. Define an operating system and discuss its functions.An operating system is a software that manages computer hardware and software resources. Its functions include providing a user interface, managing memory and storage, coordinating the execution of applications, handling input/output operations, and ensuring system security and stability.2. Explain the difference between a single-user and multi-user operating system.A single-user operating system is designed to be used by one user at a time. It provides a user interface and manages the resources on the computer for the sole user. A multi-user operating system, on the other hand, allows multiple users to access the system simultaneously, sharing resources and executing their own programs concurrently.3. Discuss the concept of virtualization and its advantages.Virtualization is the process of creating a virtual version of a computer system or resources. It allows multiple operating systems to run on a single physical machine, enabling better resource utilization, cost savings, and improved flexibility. Virtualization also provides isolation between different virtual machines, enhancing security and system stability.In conclusion, this article provides a brief overview of the topics covered in the second edition of "Introduction to Computers." It includes explanations and answers to selected exercises, helping readers understand the fundamental concepts of computer science and technology. By studying these topics, readers can gain a strong foundation in computer knowledge and skills.。

ANSWER SHEET.(40points)Text1France,which prides itself as the global innovator of fashion,has decided its fashion industry has lost an absolute right to define physical beauty for women.Its lawmakers gave preliminary approval last week to a law that would make it a crime to employ ultra-thin models on runways.The parliament also agreed to ban websites that“incite excessive thinness”by promoting extreme dieting.Such measures have a couple of uplifting motives.They suggest beauty should not be defined by looks that end up impinging on health.That's a start.And the ban on ultra-thin models seems to go beyond protecting models from starving themselves to death-as some have done.It tells the fashion industry that it must take responsibility for the signal it sends women,especially teenage girls,about the social tape-measure they must use to determine their individual worth.The bans,if fully enforced,would suggest to women(and many men)that they should not let others be arbiters of their beauty.And perhaps faintly,they hint that people should look to intangible qualities like character and intellect rather than dieting their way to size zero or wasp-waist physiques.The French measures,however,rely too much on severe punishment to change a culture that still regards beauty as skin-deep-and bone-showing.Under the law,using a fashion model that does not meet a government-defined index of body mass could result in a$85,000fine and six months in prison.The fashion industry knows it has an inherent problem in focusing on material adornment and idealized body types.In Denmark,the United States,and a few other countries,it is trying to set voluntary standards for models and fashion images that rely more on peer pressure for enforcement.In contrast to France’s actions,Denmark’s fashion industry agreed last month on rules and sanctions regarding the age,health,and other characteristics of models.The newly revised Danish Fashion Ethical Charter clearly states:“We are aware of and take responsibility for the impact the fashion industry has on body ideals, especially on young people.”The charter’s main tool of enforcement is to deny access for designers and modeling agencies to Copenhagen Fashion Week(CFW),which is run by the Danish Fashion Institute.But in general it relies on a name-and-shame method of compliance.Relying on ethical persuasion rather than law to address the misuse of body ideals may be the best step.Even better would be to help elevate notions of beauty beyond the material standards of a particular industry.21.According to the first paragraph,what would happen in France?[A]New runways would be constructed.[B]Physical beauty would be redefined.[C]Websites about dieting would thrive.[D]The fashion industry would decline.22.The phrase“impinging on”(Line2,Para.2)is closest in meaning to_____.[A]heightening the value of[B]indicating the state of[C]losing faith in[D]doing harm to23.Which of the following is true of the fashion industry?[A]New standards are being set in Denmark.[B]The French measures have already failed.[C]Models are no longer under peer pressure.[D]Its inherent problems are getting worse.24.A designer is most likely to be rejected by CFW for_____.[A]pursuing perfect physical conditions.[B]caring too much about models’character.2016年考研英语一真题及大师兄版解析29.The author holds that George Osborne’s preference_____.[A]reveals a strong prejudice against urban areas.[B]shows his disregard for the character of rural areas.[C]stresses the necessity of easing the housing crisis.[D]highlights his firm stand against lobby pressure.30.In the last paragraph,the author shows his appreciation of_____.[A]the size of population in Britain[B]the political life in today’s Britain[C]the enviable urban lifestyle in Britain[D]the town-and-country planning in BritainText3“There is one and only one social responsibility of business,”wrote Milton Friedman,a Nobel Prize-winning economist,“That is,to use its resources and engage in activities designed to increase its profits.”But even if you accept Friedman’s premise and regard corporate social responsibility(CSR)policies as a waste of shareholders’money,things may not be absolutely clear-cut.New research suggests that CSR may create monetary value for companies—at least when they are prosecuted for corruption.The largest firms in America and Britain together spend more than$15billion a year on CSR,according to an estimate by EPG,a consulting firm.This could add value to their businesses in three ways.First,consumers may take CSR spending as a“signal”that a company’s products are of high quality.Second,customers may be willing to buy a company’s products as an indirect way to donate to the good causes it helps.And third,through a more diffuse“halo effect,”whereby its good deeds earn it greater consideration from consumers and others.Previous studies on CSR have had trouble differentiating these effects because consumers can be affected by all three.A recent study attempts to separate them by looking at bribery prosecutions under America’s Foreign Corrupt Practices Act(FCPA).It argues that since prosecutors do not consume a company’s products as part of their investigations,they could be influenced only by the halo effect.The study found that,among prosecuted firms,those with the most comprehensive CSR programmes tended to get more lenient penalties.Their analysis ruled out the possibility that it was firms’political influence,rather than their CSR stand,that accounted for the leniency:Companies that contributed more to political campaigns did not receive lower fines.In all,the study concludes that whereas prosecutors should only evaluate a case based on its merits,they do seem to be influenced by a company’s record in CSR.“We estimate that either eliminating a substantial labour-rights concern,such as child labour,or increasing corporate giving by about20%results in fines that generally are40%lower than the typical punishment for bribing foreign officials,”says one researcher.Researchers admit that their study does not answer the question of how much businesses ought to spend on CSR.Nor does it reveal how much companies are banking on the halo effect,rather than the other possible benefits,when they decide their do-gooding policies.But at least they have demonstrated that when companies get into trouble with the law,evidence of good character can win them a less costly punishment.31.The author views Milton Friedman’s statement about CSR with_____.[A]tolerance[B]skepticism[C]uncertainty[D]approval32.According to Paragraph2,CSR helps a company by_____.[A]guarding it against malpractices[B]protecting it from consumers[C]winning trust from consumers[D]raising the quality of its products33.The expression“more lenient”(Line2,Para.4)is closest in meaning to_____.[A]more effective[B]less controversial[C]less severe[D]more lasting34.When prosecutors evaluate a case,a company’s CSR record_____.[A]legacy businesses are becoming outdated.[B]cautiousness facilitates problem-solving.[C]aggressiveness better meets challenges.[D]traditional luxuries can stay unaffected.40.Which of the following would be the best title of the text?_____.[A]Shift to Online Newspapers All at Once[B]Cherish the Newspapers Still in Your Hand[C]Make Your Print Newspapers a Luxury Good[D]Keep Your Newspapers Forever in FashionPart BDirections:Read the following text and answer the questions by choosing the most suitable subheading from the list A-G for each of the numbered paragraphs(41-45).There are two extra subheadings.Mark your answers on the ANSWER SHEET.(10point)[A]Create a new image of yourself[B]Have confidence in yourself[C]Decide if the time is right[D]Understand the context[E]Work with professionals[F]Make it efficient[G]Know your goalsNo matter how formal or informal the work environment,the way you present yourself has an impact.This is especially true in the first impressions.According to research from Princeton University,people assess your competence,trustworthiness,and likeability in just a tenth of a second,solely based on the way you look.The difference between today’s workplace and the“dress for success”era is that the range of options is so much broader.Norms have evolved and fragmented.In some settings,red sneakers or dress T-shirts can convey status;in others not so much.Plus,whatever image we present is magnified by social-media services like LinkedIn.Chances are,your headshots are seen much more often now than a decade or two lennials,it seems,face the paradox of being the least formal generation yet the most conscious of style and personal branding. It can be confusing.So how do we navigate this?How do we know when to invest in an upgrade?And what’s the best way to pull off one that enhances our goals?Here are some tips:41.__________________As an executive coach,I’ve seen image upgrades be particular helpful during transitions—when looking for a new job,stepping into a new or more public role,or changing work environments.If you’re in a period of change or just feeling stuck and in a rut,now may be a good time.If you’re not sure,ask for honest feedback from trusted friends,colleagues and professionals.Look for cues about how others perceive you.Maybe there’s no need for an upgrade and that’s OK.42.__________________Get clear on what impact you’re hoping to have.Are you looking to refresh your image or pivot it?For one person,the goal may be to be taken more seriously and enhance their professional image.For another,it may be to be perceived as more approachable,or more modern and stylish.For someone moving from finance to advertising, maybe they want to look more“SoHo.”(It’s OK to use characterizations like that.)43.__________________Look at your work environment like an anthropologist.What are the norms of your environment?What conveys status?Who are your most important audiences?How do the people you respect and look up to present themselves?The better you understand the cultural context,the more control you can have over your impact.44.__________________Enlist the support of professionals and share with them your goals and context.Hire a personal stylist,or use the free styling service of a store like J.Crew.Try a hair stylist instead of a barber.Work with a professional photographer instead of your spouse or friend.It’s not as expensive as you might think.45.__________________The point of a style upgrade isn’t to become more vain or to spend more time fussing over what to wear. Instead,use it as an opportunity to reduce decision fatigue.Pick a standard work uniform or a few go-to options. Buy all your clothes at once with a stylist instead of shopping alone,one article of clothing at a time.Section III TranslationDirections:Read the following text carefully and then translate the underlined segments into Chinese.Your translation should be written clearly on the ANSWER SHEET.(10points)Mental health is our birthright.(46)We don’t have to learn how to be mentally healthy;it is built into us in the same way that our bodies know how to heal a cut or mend,a broken bone.Mental health can’t be learned,only reawakened.It is like immune system of the body,which under stress or through lack of nutrition or exercise can be weakened,but which never leaves us.When we don’t understand the value of mental health and we don’t know how to gain access to it,mental health will remain hidden from us.(47)Our mental health doesn’t go anywhere; like the sun behind a cloud,it can be temporarily hidden from view,but it is fully capable of being restored in an instant.Mental health is the seed that contains self-esteem–confidence in ourselves and an ability to trust in our common sense.It allows us to have perspective on our lives—the ability to not take ourselves too seriously,to laugh at ourselves,to see the bigger picture,and to see that things will work out.It’s a form of innate or unlearned optimism.(48)Mental health allows us to view others with sympathy if they are having troubles,with kindness if they are in pain,and with unconditional love no matter who they are.Mental health is the source of creativity for solving problems,resolving conflict,making our surroundings more beautiful,managing our home life,or coming up with a creative business idea or invention to make our lives easier.It gives us patience for ourselves and toward others as well as patience while driving,catching a fish,working on our car,or raising a child.It allows us to see the beauty that surrounds us each moment in nature,in culture,in the flow of our daily lives.(49)Although mental health is the cure-all for living our lives,it is perfectly ordinary as you will see that it has been there to direct you through all your difficult decisions.It has been available even in the most mundane of life situations to show you right from wrong,good from bad,friend from foe.Mental health has commonly been called conscience,instinct,wisdom,common sense,or the inner voice.We think of it simply as a healthy and helpful flow of intelligent thought.(50)As you will come to see,knowing that mental health is always available and knowing to trust it allow us to slow down to the moment and live life happily.SectionⅣWritingPart A51.Directions:Suppose you are a librarian in your university.Write a notice of about100words providing the newly-enrolled international students with relevant information about the library.You should write neatly on the ANSWER SHEET.Do not sign your own name at the end of the e“Li Ming”instead.Do not write the address.(10points)Part B52.Directions:Write an essay of160-200words based on the following pictures.In your essay you should1)describe the drawing briefly,2)explain its intended meaning,and3)give your comments.You should write neatly on the ANSWER SHEET.(20points)2016年全国硕士研究生入学统一考试英语一试题大师兄版参考答案Section I Use of English(10points)1.A B C D2.A B C D3.A B C D4.A B C D5.A B C D6.A B C D7.A B C D8.A B C D9.A B C D10.A B C D11.A B C D12.A B C D13.A B C D14.A B C D15.A B C D16.A B C D17.A B C D18.A B C D19.A B C D20.A B C DSection II Reading Comprehension(50points)Part A(40points)21.A B C D22.A B C D23.A B C D24.A B C D25.A B C D26.A B C D27.A B C D28.A B C D29.A B C D30.A B C D31.A B C D32.A B C D33.A B C D34.A B C D35.A B C D36.A B C D37.A B C D38.A B C D39.A B C D40.A B C DPart B(10points)41.A B C D E F G42.A B C D E F G43.A B C D E F G44.A B C D E F G45.A B C D E F G注：第29题有争议，大师兄版选B，新东方版、沪江版选A。

In C99, we can avoid the cast by using the %zu conversion specification.Chapter 8Answers to Selected Exercises1.
