We may not be able to see the limits of our own abilities, so we do ambitious things that are completely beyond us. Our career masters can see our good qualities and our limitations ___54_ . They may tell us that we haven’t the ability to deal with people and would make good businessmen. We refuse to take their evaluation. We keep on trying. Many years and many _55__ later we are forced to accept their 56___ . But what a waste of time our ill-founded ambition has caused us!Secondly, our ambition can be too _57__. We devote our attention to one narrow aim, such as getting distinctions in our science subjects. Everything that may draw us away from this aim is cutout of our lives. In the end we get our distinctions. But what damage we have _58__ ourselves in the process! We are isolated beings who only care about a particular examination.

BSc Environmental and Sustainability（C）More than a year after BMW Manufacturing Co. announced plans to convert landfill gas to electricity , officials say the project has exceeded expectations .It’s good news for similar projects being considered throughout the state .A project in Lee Country should begin operation in November and another in Anderson should be running by next spring . Carbon dioxide emissions were reduced by 34,000 tons in the last nine months of 2011because the plant used less natural gas and electricity and because the methane gas emissions from the landfill were captured.BMW is on target to eliminate annually the equivalent of emissions from more than 60,000 cars . “ We think we are on target for about 55,000 tons ,as long as we operate this ,”said DuncanSeaman,BMW facilities and energy manager. In addition to reducing emissions ,BMW saves about $1milion a year in energy costs . “The reality of the project has definitely exceeded our expectations,”Seman said . The methane gas generated by the decaying waste is shipped about 10 miles to the plant from the landfill. The energy is used in various processes including the plant shop ,assembly lines and body lines , and to heat and cool the facility.Other officials are taking notice,too. “I had an international engineer come by my office the other day and tell me the BMW Palmetto project had raised the awareness of landfill gas to energy all over the world ,” said Sonny Dubose , program manager for the state Office of Energy . The original expectation was the gas would allow the plant to run tow of its four turbines full time. “The reality has been very good quality landfill gas ,”Seaman said . “ The equipment has run very well . We have had very high availability . We’ve been able to operate –more than we expected –all four turbines ,except for maintenance.”72.The carbon dioxide emissions of BMW reduction was mainly due to_______.A. the elimination of the emissions from more than 60,000 carsB.the use of natural gas rather than coalC.the decline in the use of natural gas and eletricityD.the methan in the landfill raises the efficiency of the energy73. According to the third paragragh ,which of the following is true?A. The company can produce 60,000 cars every yearB.55,000 tons of methane gas emissions will be eliminatedC.60,000 cars will be fueled by methane gasD.The project has achieved the original goal of BMW Company.74. According to what Sonny Dubose said, we can infer that _____.A. landfill gas may be used all over the world in the futureB. the gas allows the plant to run two of its four turbines full timeC. maintaining the four turbines saves lots of energyD. the original expectation is unreasonable75. Which of the following expresses the main idea of the passage?A. Carbon dioxide emissions can be reduced by use of landfill gas.B. BMW turns landfill gas into electricity.C. BMW’s proj ect always has exceeded expectations.D. There’ll be a world-wide project to turn landfill gas into electricity.Section CDirections: Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need.A. Insurance makes up for almost any kind of loss.B. Savings are the best way to protest against financial losses.C. Insurance companies in the U.S..D. Insurance can provide protection against financial losses.E. Financial loss is inevitable.F. Many share few people’s losses.76.Each minute of the day or night, everyone faces a possible financial loss. A home may be destroyed by fire, damaged by lightning, or leveled by a tornado. Personal belongings may be stolen. A car may be damaged in an accident, or it may cause injury to people and property. Income may be lost as the result of the death, disability, or unemployment of a family wage earner. The chance that a loss of this kind may occur is called an economic risk.77.Savings provide one way to take care of financial losses. But savings are not the answer to large losses. The best way to guard against large financial losses is through insurance. The purpose of insurance is to provide protection against financial loss at a reasonable cost. This is possible only when the cost of insurance is shared by many people who face a similar risk. But not all of them are likely to have actual losses at the same time.78.Almost 4,800 companies in the United States are in the business of providing insurance protection. These businesses are called insurance companies. Because most insurance companies operate on a big scale, they provide a way for large numbers of people to share their losses.79.The premiums(保险金) paid by all policyholders are used to pay those who have losses. In this way, a loss that might result in great financial hardship for one person or household is shared by many people.80.Insurance can provide protection against almost any kind of loss. Singers may insure their voices. Photographers may insure their negatives. The owner of a home freezer may insure against food loss in case of power failure. A business owner can insure his or her place of business. A business owner can also insure against a loss of profits during a shutdown following a fire or damaging accident. However, the kinds of insurance protection that most people buy can be divided into three broad groups: property and liability insurance, life insurance, and health insurance.Section DDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.When aluminum was first produced about a hundred and fifty years ago, it was so difficult to separate from the ores in which it was found that its price was higher than that of gold. The price remained high until a new process was discovered for refining the metal with the aid of electricit y approximately three quarters of a century later. The new method was so such cheaper that alu minum became practical for many purposes, one of the first which was making pots and pans.Aluminum is lightweight, rustproof and easily shaped into different forms. By mixing it with o ther metals, scientists have been able to produce a variety of alloys, some of which have the stre ngth of steel but weigh only one third as much.Today, the uses of aluminum are innumerable. Perhaps its most important use is in transport ation.Aluminum is found in the engines of automobiles, in the hulls of boats. It is also used in man y parts of airplanes. In fact, the huge "airbus" planes would probably never have been produced if aluminum did not exist. By making vehicles lighter in weight aluminum has greatly reduced the a mount of fuel needed to move them. Aluminum is also being used extensively in the building ind ustry in some countries.Since aluminum is such a versatile (多用的) metal, it is fortunate that bauxite（铝土矿）, which is one of its chief sources, is also one of the earth’s most plentiful substances. As the source of aluminum is almost inexhaustible, we can expect that more and more uses will be foun d for this versatile metal.(Note: Answer the questions or complete the statements in NO MORE THAN EIGHT WORDS) 81. The price of aluminum _____________________after people discovered a new refining process with the aid of electricity.82. What is the main future of aluminum?83. Why is aluminum important in making vehicles?84. Aluminum seems to have limitless use probably because___________第二卷Translation1.他会上提的建议值得进一步考虑。

2012 年普通高等学校招生全国统一考试模拟试题衡水中学调研卷1
2012 年普通高等学校招生全国统一考试模拟试题衡水中学调研卷·语文（一）本试卷为试题卷，分为第I 卷（阅读题）和第n 卷（表达题）两部分。
本试卷满分150 分，考试时间为巧O 分钟。
第I 卷（阅读题共70 分）甲必考题一、现代文阅读（9 分，每小题3 分）阅读下面的文字，完成1 一3 题。
文学家不应放弃精神担当贺绍俊中国文人具有深厚的精神担当的品格，这种品格突出体现为一种忧国忧民、济世救国的政治情怀。
从孔夫子的“大道天下”，到屈原的“众人皆醉我独醒”，到范仲淹的“先天下之忧而忧，后天下之乐而乐”，这一切编织成一个绵延的思想传统。
这一思想传统移植在中国现代意义上的知识分子身上，蝶化成“五四”启蒙精神。
因此从精神谱系上说，中国现代意义上的知识分子与中国传统文人是一脉相承的。
这就决定了中国现代文学强烈的现实品格和浓郁的政治情怀。
中国现代文学正是以其浓郁的政治情怀，才成为思想启蒙的重要营垒，才密切融入中国现代化运动中，也才有效地承载中国知识分子的精神担当。
知识分子的政治情怀不会始终与政治现实尤其是政治权力协调一致，二者之间的矛盾汁立往往导致文学屈从于政治现实、知识分子逐渐丧失独立品格。
改革开放为知识分子独立意识的觉醒创造了条件，但当时不少知识分子把独立品格与政治情怀对立起来，甚至质疑忧国忧民传统的正确性，从而放弃了对于社会的精神担当。
因为对社会职责的放弃，知识分子独立意识的觉醒反而导致了知识分子的自我放逐。
这一点在文学中表现得尤为突出：上世纪80 年代的文学一度引领着思想解放的潮流，但到了80 年代末期，伴随着“向内转”，文学逐渐从政治、思想、社会批判等阵地大幅度地后撤。
所幸的是，淡薄政治情怀并没有成为文学的主潮，更多作家则是在尝试着以新的文学叙事来表达政治情怀，日常生活叙事逐渐兴起并蔚为大观，从根本上改变了宏大叙事的一统天下，但是日常生活叙事并没有取代宏大叙事，相反激发宏大叙事突破过去的僵化模式，构成了当代文学中宏大叙事和日常生活叙事交相辉映的状况。
