TranslationA.(Refer to the relevant part of the Chinese translation)B.In September 1995, anti-hydrogen atom—an anti-matter atom—was successfullydeveloped in European Particle Physics Laboratory in Switzerland. After the startling news spread out, scientists in the West who were indulged in the research of anti-matter were greatly excited. While they were attempting to produce and store anti-matter as the energy for spacecraft, they raised a new question: Many of the mysterious nuclear explosions in the recent one hundred years are connected with anti-matter. That is to say, these hard-to-explain explosions are tricks played by anti-mat ter. They are the “destruction”phenomenon caused by the impact between matter and anti-matter.V.

To bribe means to influence the behavior or judgment of others (usually in positions ofpower) unfairly or illegally by offering them favors or gifts.2. Gravity is defined as the natural force by which objects are attracted to each other,especially that by which a large mass pulls a smaller one to it.3. The millennium bug refers to the computer glitch that arises from an inability of thesoftware to deal correctly with dates of January 2000 or later.4. Globalization is understood as the development so as to make possible internationalinfluence or operation.II. Write a one-paragraph definition of the following words.1. hypothesisA hypothesis is an idea which is suggested as a possible way of explaining facts,proving an argument, etc. Through experiments, the hypothesis is either accepted as true (possibly with improvements) or cast off.2. scienceScience is defined as the intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment.3. superstitionSuperstition refers to a belief which is not based on reason or fact but on old ideas about luck, magic, etc. For example, it is a common superstition that black cats are unlucky.4. pessimismPessimism is a tendency to give more attention to the bad side of a situation or to expect the worst possible result. A person with pessimism is a pessimist who thinks that whatever happens is bad.5. individualismIndividualism is the idea that the rights and freedom of the individual are the most important rights in a society. It has a bad sense in that little attention is paid to the rights of the collective or a good one in that independence is emphasized rather than dependence on others.Text 2 Physics Awaits New Options as Standard Model IdlesI.

Most of the pieces are there,and even unfinished, it is arguably the most brilliant opus in the literature of physics. With great precision, it describes all known matter – all the subatomic particles such as quarks and leptons –as well as the forces by which those particles interact with one another.These forces are electromagnetism, which describes how charged objects feel each other’s influence: the weak force, which explains how particles can change their identities, and the strong force, which describes how quarks stick together to form protons and other composite particles. But as lovely as the Standard Model’s description is, it is in pieces, and some of those pieces – those that describe gravity – are missing. It is a few shards of beauty that hint at something greater, like a few lines of Sappho on a fragment of papyrus. V.

The five scientists who won the 1996 Nobel Prize point out that the present prosperityand development are based on the fruits of basic scientific research and the negligence of basic scientific research will threaten human development of the 21st century.EU countries noticed that one of their weaknesses is “insufficient investment in research and development.” Korea and Singapore do not hesitate to pour money into research and development. The developed countries in the West have used most of the scientific and technological development resources for the research and development of new and high technology. This has become an obvious trend at present. It is evident from the experiences of various countries that new and high technology can create and form new industries, open up and set up new markets. The innovation of traditional industries with new and high technology is a key method to strengthen the competitive competency of an enterprise.VI.

TranslationA.(Refer to the relevant part of the Chinese translation)B. There are only two forms of human spiritual creation: science and poetry. The formergives us convenience; and the latter gives us comfort. In more common words, the former enables us to have food to eat when we are hungry; and the latter makes us aware that eating is something more than eating, and it is very interesting as well. To have science without poetry, atomic bomb will be detonated; to have poetry without science, poets will starve to death.Scientists should not despise poets; and poets should not remain isolated from scientists.If the two fields conflict each other, human beings would be on the way to doom. In fact, the greatest scientists like Newton, Einstein and Mrs. Currie were all endowed with poetic spirit.I assert that in observing the apple falling to the ground, Newton not only discovered thegravity of the earth, he also wrote a beautiful poem.V.

C4. B5. A6. CIV. TranslationA.(Refer to the relevant part of the Chinese translation)B. At present there exist two conflicting tendencies towards the development of science andtechnology. The opponents of science hold that the development of modern science has not brought blessings to human beings, instead it has brought human beings to the very edge of disaster and peril. On the other hand, the proponents of scientific and technological progress maintains that the crises facing human beings today—such as environmental pollution, ecological unbalance, natural resource exhaustion—are the natural consequences of the development of science, and the solution to which lies in the further development of science. Both of the above tendencies are reasonable in a sense with their respective one-sided view. If we view the development of modern science and technology from the point of view of our times and with dialectic viewpoints, we can find out that the problem facing modern science and technology is not how to understand the progress of modern science and technology, but how to find out the theoretical basis for the further development of science and technology in order to meet the needs of the times.V.

Human beings have long been attempting sending unmanned devices, called interstellarprobes, into the outer space to understand the changes of climates, geological structures and the living beings on the stars and planets out there. A probe is usually sent into the orbit of the earth by “riding” a spacecraft or carrier rockets. After its orbital adjustments are made, the rocket engine is ignited and the probe continues its journey to the orbit of the other star or planet. With the rocket engine broken off, the probe immediately spreads its solar-cell sails and antenna, controlling its posture with sensors. When convinced that it is in the orbit of the targeted star, the probe starts its propeller and flies to the preset destination.V.

The energy released from nuclear fusion is much more than that from nuclear fission, andthe radioactivity given out from fusion is only one hundredth of that from fission. The major fuel used for nuclear fusion is hydrogen and its isotopes, deuterium and tritium, among which deuterium could be directly extracted from sea water. The energy of deuterium contained in one liter of sea water is equal to 300 liters of petroleum. In the ocean there are about 35,000 billion tons of deuterium, which could be used for more than one billion years.

(四)Verifiability （可核性）1QC26. Verifiability helps assure users that information faithfully represents the economic phenomena it purports to represent. Verifiability means that different knowledgeable and independent observers could reach consensus, although not necessarily complete agreement, that a particular depiction is a faithful representation. Quantified information need not be a single point estimate to be verifiable. A range of possible amounts and the related probabilities also can be verified.QC27. Verification can be direct or indirect. Direct verification means verifying an amount or other representation through direct observation, for example, by counting cash. Indirect verification means checking the inputs to a model, formula, or other technique and recalculating the outputs using the same methodology. An example is verifying the carrying amount of inventory by checking the inputs (quantities and costs) and recalculating the ending inventory using the same cost flow assumption (for example, using the first-in, first-out method).QC28. It may not be possible to verify some explanations and forward-looking financial information until a future period, if at all. To help users decide whether they want to use that information, it normally would be necessary to disclose the underlying assumptions, the methods of compiling the information, and other factors and circumstances that support the information. Timeliness （及时性）2QC29. Timeliness means having information available to decision makers in time to be capable of influencing their decisions. Generally, the older the information is, the less useful it is. However, some information may continue to be timely long after the end of a reporting period because, for example, some users may need to identify and assess trends.UnderstandabilityQC30. Classifying, characterizing, and presenting information clearly and concisely makes it understandable. （可理解性）3QC31. Some phenomena are inherently complex and cannot be made easy to understand. Excluding information about those phenomena from financial reports might make the information in those financial reports easier to understand. However, those reports would be incomplete and therefore potentially misleading.QC32. Financial reports are prepared for users who have a reasonable knowledge of business and economic activities and who review and analyze the information diligently. At times, even well-informed and diligent users may need to seek the aid of an adviser to understand information about complex economic phenomena.Applying the Enhancing Qualitative CharacteristicsQC33. Enhancing qualitative characteristics should be maximized to the extent possible. However, the enhancing qualitative characteristics, either individually or as a group, cannot make information useful if that information is irrelevant or not faithfully represented.QC34. Applying the enhancing qualitative characteristics is an iterative process that does not follow a prescribed order. Sometimes, one enhancing qualitative characteristic may have to be diminished to maximize another qualitative characteristic. For example, a temporary reduction in comparability as a result of prospectively applying a new financial reporting standard may be worthwhile to improve relevance or faithful representation in the longer term. Appropriate disclosures may partially compensate for noncomparability.The Cost Constraint（成本约束）4on Useful Financial Reporting（有用的财务报表）5QC35. Cost is a pervasive constraint on the information that can be provided by financialreporting. Reporting financial information imposes costs, and it is important that those costs are justified by the benefits of reporting that information. There are several types of costs and benefits to consider.QC36. Providers of financial information （财务信息）6expend most of the effort involved in collecting, processing, verifying, and disseminating financial information, but users ultimately bear those costs in the form of reduced returns. Users of financial information also incur costs of analyzing and interpreting the information provided. If needed information is not provided, users incur additional costs to obtain that information elsewhere or to estimate it.QC37. Reporting financial information that is relevant and faithfully represents what it purports to represent helps users to make decisions with more confidence. This results in more efficient functioning of capital markets and a lower cost of capital for the economy as a whole. An individual investor, lender, and other creditor also receive benefits by making more informed decisions. However, it is not possible for general purpose financial reports to provide all the information that every user finds relevant.QC38. In applying the cost constraint(约束成本)7, the Board assesses whether the benefits of reporting particular information are likely to justify the costs incurred to provide and use that information. When applying the cost constraint in developing a proposed financial reporting standard, the Board seeks information from providers of financial information, users, auditors, academics, and others about the expected nature and quantity of the benefits and costs of that standard. In most situations, assessments are based on a combination of quantitative and qualitative information.QC39. Because of the inherent subjectivity, different individuals’ assessments of the costs and benefits of reporting particular items of financial information will vary. Therefore, the Board seeks to consider costs and benefits（成本和收益）8 in relation to financial reporting generally, and not just in relation to individual reporting entities. That does not mean that assessments of costs and benefits always justify the same reporting requirements for all entities. Differences may be appropriate because of different sizes of entities, different ways of raising capital (publicly or privately), different users’ needs, or other factors. This Concepts Statement was adopted by the unanimous vote of the five members of the Financial Accounting Standards Board:Robert H. Herz, ChairmanThomas J. LinsmeierLeslie F. SeidmanMarc A. SiegelLawrence W. SmithAPPENDIX: BASIS FOR CONCLUSIONS FORCHAPTER 3IntroductionBC3.1 This basis for conclusions summarizes considerations of the Board in reaching the conclusions in Chapter 3, Qualitative Characteristics （质量特征）9of Useful Financial Information. It includes reasons for accepting some alternatives and rejecting others. Individual Board members gave greater weight to some factors than to others.BC3.2 The Board developed this chapter jointly with the International Accounting Standards Board (IASB). Consequently, this basis for conclusions also includes some references to the IASB’s literature.BackgroundBC3.3 The Board began the process of developing the qualitative characteristics of useful financial information by reviewing its own framework and concepts as well as those of other standard setters. In July 2006, the Board published for public comment a Discussion Paper on this topic. That same paper also was published by the IASB. The Board and the IASB received 179 responses. In its redeliberations of the issues on this topic, the Board considered all of the comments received and information gained from other outreach initiatives. In May 2008, the Board and the IASB jointly published an Exposure Draft. The Boards received 142 responses. The Board reconsidered all of the issues. This document is the result of those reconsiderations. The Objective of Financial Reporting10and the Qualitative Characteristics of Useful Financial InformationBC3.4 Alternatives（备选方案）11 are available for all aspects of financial reporting, including recognition, derecognition, measurement, classification, presentation, and disclosure. When developing financial reporting standards, the Board will choose the alternative that goes furthest towards achieving the objective of financial reporting. Providers of financial information also will have to choose among the alternatives if there are no applicable standards available, or if application of a particular standard requires judgments or options, to achieve the objective of financial reporting.BC3.5 Chapter 1 specifies that the objective of general purpose financial reporting is to provide financial information about the reporting entity that is useful to existing and potential investors, lenders, and other creditors in makingdecisions about providing resources to the entity. The decision makers on which this Conceptual Framework focuses are existing and potential investors, lenders, and other creditors.BC3.6 That objective by itself leaves a great deal to judgment and provides little guidance on how to exercise that judgment. This chapter describes the first step in making the judgments needed to apply that objective. It identifies and describes the qualitative characteristics that financial information should have if it is to meet the objective of financial reporting. It also discusses cost, which is a pervasive constraint on financial reporting.BC3.7 Subsequent chapters will use the qualitative characteristics to help guide choices about recognition, measurement, and the other aspects of financial reporting.Fundamental and Enhancing Qualitative CharacteristicsBC3.8 This chapter distinguishes between the fundamental qualitative characteristics（基本质量特征）12that are the most critical, and the enhancing qualitative characteristics（增进的质量特征）13that are less critical but still highly desirable. The Discussion Paper did not explicitly distinguish between those qualitative characteristics. The Board made the distinction later because of confusion among respondents to the Discussion Paper about how the qualitative characteristics relate to each other.BC3.9 Some respondents to the Exposure Draft stated that all of the qualitative characteristics should be considered equal and that the distinction between fundamental and enhancing qualitative characteristics was arbitrary. Others said that the most important qualitative characteristic differs depending on the circumstances; therefore, differentiating among the qualitative characteristics was not appropriate.BC3.10 The Board does not agree that the distinction is arbitrary. Financial information without the two fundamental qualitative characteristics of relevance and faithful representation isnot useful, and it cannot be made useful by being more comparable, verifiable, timely, or understandable. However, financial information that is relevant and faithfully represented may still be useful even if it does not have any of the enhancing qualitative characteristics. Fundamental Qualitative CharacteristicsRelevance （相关性）14BC3.11 It is self-evident that financial information is only useful for making a decision if it is capable of making a difference in that decision. Relevance is the term used in the Conceptual Framework to describe that capability. It is a fundamental qualitative characteristic of useful financial information.BC3.12 The definition of relevance in the Conceptual Framework is consistent with the definition in FASB Concepts Statement No. 2, Qualitative Characteristics of Accounting Information. The definition of relevance in the Framework (1989) was that information is relevant only if it actually makes a difference in users’ decisi ons. However, users consider a variety of information from many sources, and the extent to which a decision is affected by a particular economic phenomenon is difficult, if not impossible, to determine, even after the fact. BC3.13 In contrast, whether information is capable of making a difference in a decision (relevance as defined in the Conceptual Framework) can be determined. One of the primary purposes of publishing Exposure Drafts and other due process documents is to seek the views of users on whether information that would be required by proposed financial reporting standards is capable of making a difference in their decisions. The Board also assesses relevance by meeting with users to discuss proposed standards, potential agenda decisions, effects on reported information from applying recently implemented standards, and other matters.Predictive and confirmatory valueBC3.14 Many decisions by investors, lenders, and other creditors are bason implicit or explicit predictions about the amount and timing of the return on equity investment, loan, or other credit instrument. Consequently, informationcapable of making a difference in one of those decisions only if it will help useto make new predictions, confirm or correct prior predictions, or both (whichthe definition of predictive or confirmatory value).BC3.15 The Framework (1989) identified predictive value （预测值）15and confirmatovalue（验证价值）16 as components of relevance, and Concepts Statement 2 referred predictive value and feedback value. The Board concluded that confirmatovalue and feedback value were intended to have the same meaning. The Boaand the IASB agreed that both Boards would use the same term (confirmatovalue) to avoid giving the impression that the two frameworks were intended be different.The difference between predictive value and related statistical termsBC3.16 Predictive value, as used in the Conceptual Framework, is not the same as predictability and persistence as used in statistics. Information has predictive value if it can be used in making predictions about the eventual outcomes of past or current events. In contrast, statisticians use predictability to refer to the accuracy with which it is possible to foretell the next number in a series and persistence to refer to the tendency of a series of numbers to continue to change as it has changed in the past.可核性1QC26 可核实性帮助信息使用者确认信息，如实反映了它旨在反映的经济现象。

高中生英语作文《个人与集体的关系》The Relationship between the Individual and the CollectiveIn modern society, the relationship between the individual and the collective has been a heated topic of discussion.Some people emphasize the importance of the collective while others argue that individual freedom should be given priority.From my perspective, both the individual and the collective are interdependent and should be balanced.On one hand, the collective represents the overall interest of a group of people.It provides a sense of belonging, security, and identity.In many cultures, the collective is considered more important than the individual.This is particularly true in Asian countries, where harmony and unity are highly valued.For example, in China, the concept of 'face' reflects the importance of maintaining the reputation and honor of the family or organization.In such cultures, individuals are often expected to sacrifice their personal desires for the benefit of the collective.On the other hand, the individual is the building block of society.Individual creativity, innovation, and uniqueness contribute to the progress and development of the collective.Without individuals who think critically and take initiative, the collective would stagnate.In recent years, there has been a growing emphasis on individualism in Western countries.People are encouraged to pursue their own dreams and goals, and the value of personal freedom and self-expression is highly regarded.To maintain a healthy relationship between the individual and the collective, it is important to strike a balance.While respecting the collective interest, individuals should also be allowed to pursue their own aspirations.This can be achieved through effective communication, mutual understanding, and compromise.Moreover, institutions and policies should be in place to protect individual rights and ensure that the collective does not infringe upon them.In conclusion, the relationship between the individual and the collective is a complex and delicate one.It is important to recognize the importance of both and strive for a balance that promotes the overall well-being of society.By doing so, we can create a harmonious environment where individuals can thrive while contributing to the collective good.。

processes as well.[E.253]191.Various machine parts can be washed very clean and will be as clean as new ones when they are treated by ultrasonic waves no matter how dirty and irregularlyshaped they may be.[E.254]CHAPTER SEVEN192.Theγ-rays are not affected by an electric field.[E.4]193.If the work piece is gabbed directly,it warps due to the body temperature.[E.5]194.If a body is acted on by a number of forces and still remains stationary,the body is said to be in equilibrium.[E.6]195.An oxidation number may be assigned to each atom in a substance by the application of simple rules.[E.7]196.The second group is composed of compounds derived from or related to benzene C6H6.[E.8]197.The crops were washed away by the flood.[E.9]198.The airplane is supported by the wings;it is propelled by the power plant;it is guided by its control surfaces.[E.10]199.This extraction rate was confirmed in batch tank tests.[E.11]200.Other advantages of our invention will be discussed in the following.[E.12]201.These problems must be solved before the test starts.[E.13]202.North China was hit by an unexpected heavy rain,which caused severe flooding.[E.14]203.The hypothesis was not accepted by most chemists until the1970s.[E.15]204.The first car driven by one of these engines was seen on the roads in1894.[E.16]。
