I believe this was triggered〔引起起〕by the oldie The Impossible Dream that was playing on the radio yesterday afternoon!In 1971, returning from our regular Friday night pregame meeting, I had no sooner walked in the door of our three-room apartment hack than the phone rang. It was the township police . They inquired if I was the football coach. I answered yes and asked if there was a problem. He said our football team had climbed the fence of the township football field and were sitting somewhere around the 50-yard line quietly. It was really not a problem. However, he thought I would like to know. I called my assistants, and made our way to the field.We met the police at the locked gate. The field was dark and silent. Then, suddenly, we heard voices singing—together and on key一the team theme song, The Impossible Dream.Silently, we listened and became overwhelmed〔压倒〕with emotion. Even the policemen had tears rolling down their cheeks. When the team had finished,创作；朱本晓 2022年元月元日they walked slowly to the now-opened gate of the field and were shocked to see us waiting there. Of course, our first words were, "What is going on?"Mike Bernert, the team captain, replied, "Well, coach, you told us to visualize our performance in our mind just before the night of the game. So we came and visualized the upcoming game while sitting on the 50-yard line. Afterward, we would sing The Impossible Dream. 〞The coaches and I were overwhelmed.

These labels show where the cocoa comes from and its quality. The special labels can lead to higher prices on the market.Henrique Almeida is the 63-year-old owner of a farm in Coaraci, in the northeastern Brazilian state of Bahia. He is pleased with the "South Bahia" geographical indication for his cocoa. "The production of fine cocoa and the creation of the geographical indication label make it possible to have a profitable business and pull our region upwards," Almeida said.For many years, farmers in Bahia had produced common cocoa, used widely in the chocolate industry. But in 1989, an outbreak of "witches' broom〞 disease sharply reduced the productivity of Bahia's cocoa trees. These trees make up to 86 percent of Brazil's national crop. At the time, Almeida, like other producers in southern Bahia, chose to improve the quality of his crop in order to be able to continue growing."When I bought the farm, standard cocoa prices were low, and cocoa farmers were unmotivated〔无动机的〕,while the chocolate market was doing well," he told the French news agency AFP. "I started growing fine cocoa to make my own chocolate and add value to my product."The label is the result of 10 years of work by Almeida and other cocoa producers, as well as cooperatives and researchers. Together, they created the South Bahia Cocoa Association to define 〔定义〕production rules. The National Institute of Industrial Property registered the GI 6 years after the first registered GI.创作；朱本晓 2022年元月元日The "South Bahia〞label is the second GI given to Brazilian cocoa. The Linhares region in the state of Espirito Santo was the first GI to be registered in 2021.

Farmers started to grow fine cocoa.D. Chocolate industry had to use common cocoa.9 .When was the " South Bahia" labeled?A. In 2021.B. In 2021.C. In 2021.D. In 2021.10.What might happen to Brazilian cocoa in the future?A. A national cocoa association may appear quickly.B. Common cocoa may disappear soon.C. Cocoa fanners may apply for more GI labels.D. Cocoa prices will be higher and higher.11 .What's the main idea of the text?A. Brazil's cocoa industry benefits from GI labels.B. Brazil's cocoa farmers are learning to make French wine.C. GI labels are making higher profits for Brazil's cocoa farmers.D. Better Brazil's cocoa trees will bring finer Brazil's cocoa.DWhile it's no surprise that heavy drinking comes with health consequences, women创作；朱本晓 2022年元月元日in particular are more likely to suffer from alcohol—including an increased risk of alcohol-related death, according to a new study.The study, published in the journal Alcoholism: Clinical and Experimental Research, looked at the death data of Americans 16 and older from 1999 to 2021. The researchers found nearly 1 million alcohol-related deaths in that time period and the largest annual increase of alcohol-related deaths occurred among Non-Hispanic white women." Historically, the most protective factor for women was that it was less common for women to drink a lot," Keith Humphreys, a professor of Stanford University tells Yahoo Lifestyle. "That was changed largely by alcohol companies. Women were targeted in advertising and it worked—and now women drink much more and now they're dying much more. 〞Excessive alcohol use can lead to several health problems over time—and women are particularly affected. "The risk of cirrhosis〔肝硬化〕and other alcohol-related liver diseases is higher for women than for men," according to the CDC. Drinking too much alcohol can also affect the brain, causing shrinkage〔收缩〕and memory loss. " Research suggests that women are weaker than men to the brain damaging effects of alcohol abuse, and the damage tends to appear with shorter periods of excessive drinking for women than for men. " Heavy drinking also influences heart health. The CDC states that studies show women who drink excessively have a higher risk of damaging the heart muscle than men, " even for women drinking at lower levels. 〞The health consequences of drinking also develop more rapidly in women than in创作；朱本晓 2022年元月元日men. " You'll commonly see a woman who hasn't been drinking alcohol as long as men and the physical punishment comes faster,〞 says Humphreys.12.How was the study done?A. By doing experiments.B. By comparing data.C. By watching closely.D. By asking and recording.13 .What's the main idea of Paragraph 3?A. It explains the reasons for women to drink.B. It compares the past and present of women.C. It shows the newest finding about women drinking.D. It comments on the terrible results of women drinking.14. How many body parts of women may be damaged by excessive drinking?A. Two.B. Three.C. Four.D. Five.15. What might be the best title for the passage?A. Women, Suffer More from DrinkingB. Drinking, Fashionable but HarmfulC. Drinking Does Harm to HealthD. Men and Women, Drink Less第二节〔一共5小题;每一小题2分，满分是10分〕根据短文内容，从短文后的选项里面选出能填入空白处的最正确选项。

下半年大学英语四级模拟试卷及答案（2）2016年下半年大学英语四级模拟试卷及答案C.Many of the inner capacities——often known as psych0—social skills——cannot be taught as subjects.They are not the same as academic or technical learning.They must rather be modeled and promoted as part of learning，and in particular by teachers.These skills have to do with the way we behave—towards other people，towards ourselves，towards the challenges and problems of life.They include skills in communicating，in making decisions and solving problems，in negotiating and expressing ourselves，in thinking critically and understanding our feelings.D.More practical life skills are the kinds of manual skills we need for the physical tasks we face.Some would include vocational skills under the heading of life skills——the ability to lay bricks.sew clothes，catch fish or repair a motorbike.These are skills by which people may earn their livelihood and which are often available to young people leaving school.In fact，very often young people learn psycho-social skills as they learn more practical skills.Learning vocational skills can be a strategy for acquiring both practical and psycho-social skills.E.We need to increase our life skills at every stage of life，so learning them may be part of early child—hood education.of primary and secondary education and of adult learning groups.Life skills can be put into the categories that the Jacques Delors report suggested;it spoke of four pillars of education，which correspond to certain kinds of life skills—Learning to know：Thinking abilities：such as problem—solving，critical thinking，decision making，understanding consequences.Learning to be：Personal abilities：such as managing stress and feelings，self-awareness，self-confidence.Learning to live together：Social abilities：such as communication，negotiation，teamwork.Learning to do： Manual skills：practicing know-how required for work and tasks.F.In today’s world all these skills are necessary, in order to face rapid change in society.This means that it is important to know how to go on learning as we require new skills for life and work.In addition，we need to know how to cope with the flood of information and turn it in touseful knowledge.We also need to learn how to handle change in society and in our own lives.G.Life skills are both concrete and abstract—practical skills can be learned directly, as a subject.For example, a learner can take a course in laying bricks and learn that skill.Other life skills，such as self-confidence，self-esteem，and skills for relating to others or thinking critically cannot be taught in such direct ways.They should be part of any learning process，where teachers or instructors are concerned that learners should not just learn about subjects，but learn how to cope with life and make the most of their potential.H.So these life skills may be learnt when learning other things.For example：Learning literacy may have a big impact on self-esteem，on critical thinking or on communication skills;Learning practical skills s ach as drivin9，healthcare or tailoring may increase self-confidence，teach problem—solving processes or help in understanding consequences.I. Whether this is true depends on the way of teachin9—what kinds of thinkin9，relationship building and communication the teacher or facilitator models themselves and promotes among the learners.It would require measuring the individual and collective progress in making the most of learning and of life，or assessing how far human potential is being realized，or estimating how well people cope with change.It is easier to measure the development of practical skills，for instance by counting the number of students who register for vocational skills courses.However, this still may not tell us how effectively these skills are being used.J.The psych0.social skills cannot easily be measured by tests and scores，but become visible in Chang behavior.Progress in this area has often been noted by teachers on reports which they make t.the parents of their pupils.The te acher’s experience of life，of teaching and of what can be expected from education in the broadest sense serve as a standard by which the growth and development of individuals can be assessed to some extent.This kind of assessment is individual and may never appear in international tables and charts.K.The current challenges relate to these difficulties：We need to recognize the importance of life skills————both practical and psycho-social—————as part of education which leads to the full development of human potential and to the development of society.The links between psycho—social skills and practical skills must be more clearly spelled out，so that educators can promote both together and find effective ways to do this.Since life skills are taught as part of a wide range of subjects，teachers need to have training in how to put them across and how to monitor learners’ growth in these areas.In designing curricula and syllabuses for academic subjects，there must be a balance between content teaching and attention to the accompanying life skills.A more conscious and deliberateeffort to promote life skills will enable learners to become more active citizens in the life of society.L. Governments should recognize and actively advocate for the transformational role of education in realizing human potential and in socio—economic development.Ensure that curricula and syllabuses address life skills and give learners the opportunity to make real-life applications of knowledge，skills and attitudes.Show how life skills of all kinds apply in the world of work，for example，negotiating and communication skills，as well practical skills.Through initial and in-service teacher training，increase the use of active and participatory learning/teaching approaches.Examine and adapt the processes and content of education so that there is a balance between academic input and life skills development.Make sure that education inspectors look not only for academic progress through teaching and learning，but also progress in the commmunication，modeling and application of life skills.Advocate for the links between primary and(early.secondary education because learning life skills needs eight or nine years and recognize that the prospect of effective secondary education is an incentive to children，and their parents，to complete primary education successfully.M.Funding agencies should support research，exchange and debate.nationally and regionally,on ways of strengthening life skills education.Support innovative(创新的.teacher training in order to combine life skills promotion into subjects across the curriculum and as a fundamental part of what school and education are about.Recognize the links between primary and secondary education in ensuring that children develop strong life skills.Support，therefore，the early years of secondaryeducation as part basic education.N. As support to governments and in cooperation with other international agencies，UNESC0：Works to define life skills better and clarify what it means to teach and learn them.Assists education. policy makers and teachers to develop and use a life skills approach to education.Advocates for the links between a life skills approach to education and broader society and human development.根据以上内容，回答46-56题。

passage is followed by some questions or unfinished statements. for each of them there are four choices marked a),b),c) and d). you should decide on the best choice and mark the corresponding letter on the answer sheet with a single line through the centre.passage one questions 21 to 25 are based on the following passage:there is a popular belief among parents that schools are no longer interested in spelling. no school i have taught in has ever ignored spelling or considered it unimportant as a basic skill there are , however, vastly different deas about how to teach it , or how much priority it must be given over general language development and writing without holding him back with the complexities of spelling?if spelling becomes the only focal point of his teacher'sinterest, clearly a bright child will be likely to "play safe". he will tend to write only words within his spelling range , choosing to avoid adventurous language. that's why teachers often encourage the early use of dictionaries and pay attention to content rather than technical ability.i was once shocked to read on the bottom of a sensitive piece of writing about a personal experience: "this work is terrible! there are far too many spelling errors and your writing is illegible ." it may have been a sharp criticism of the pupil's technical abilities in writing, but it was also a sad reflection on the teacher who had omitted to read the essay , which contained some beautiful expressions of the child's deep feelings. the teacher was not wrong to draw attention to the errors , but if his priorities had centred on the child's ideas, an expression of his disappointment with the presentation would have given the pupil more motivation to seek improvement.21.teachers differ in their opinions about ________.a)the difficulties in teaching spellingb)the role of spelling in general language developmentc)the complexities of the basic writing skillsd)the necessity of teaching

writingd)students will learn to be independent of teachers24. the writer seems to think that the teacher's judgement on that sensitive piece of writing is ______.a)reasonableb)unfairc)foolishd)careless25.the major point discussed in the passage is ________a)the importance of developing writhing skillsb)the complexities of spellingc)the correct way of marking compositionsd)the relationship between spelling and the content of a compositionpassage two questions 26 to 30 are based on the following passage: a breakthrough in the provision of energy from he sun for the european economic community (eec) could be brought forward by up the two decades, if a modest increase could be provided in the eec's research effort in this field, according to the senior eec scientists engaged in experiments in solar energy a eec's scientific laboratories at ispra, near milan.the senior west german scientist in charge of the community's solar energy programme , mr. joachim gretz, told journalists that at present levels of research spending it was most unlikely that solar energy would provide as much as three per cent of the community's energy requirements even after the year 2000. but he said that with a modest increase in the present sums, devoted by the eec to this work it was possible that the breakthrough could be achieved by the end of the next decade.mr. gratz calculates that if solar energy only provided three per cent of the eec's needs, this could still produce a saving of about a billion pounds in the present bill for imported energy each year. and he believes that with the possibility of utilizing more advanced technology in this field itmight be possible to satisfy a much bigger share of the community's future energy needs.at present the eec spends about $2.6 millions a year on solar research at ispra, one of the eec's official joint research centres, and another $3 millions a year in indirect research with universities and other independent bodies.26. the phrase "be brought forward" (lie 2, para. 1)most probably means "______"a)be expectedb)be completedc)be advancedd)be introduced27.some scientists believe that a breakthrough in the use of solar energy depends on _____.a)sufficient fundingb)further experimentsc) advanced technologyd)well-equipped laboratories28. according to mr. gretz, the present sum of money will enable the scientists to provide ______.a)more than 3% of the eec's needs after the year 2000b)only 3% of the eec's needs before the year 2000c) lees than 3% of the eec's needs before the year 2000d)3% of the eec's needs after the year 200029. which of the following is not true according to the passage?a)the eec spends one billion pounds on imported energy each year.b)at the present level of research spending, it is difficult to make any significantprogress in the provision of energy from the sun.c) lees than 3% of the eec's needs before the year 2000.d)3% of the eec's needs after the year2000.30. the application of advanced technology to research in solar energy ______.a)would lead to a big increase in research fundingb)would make it unnecessary to import oilc)would make it possible to meet the future energy needs of the eecd)would provide a much greater proportion of the community's future energy needspassage three questions 31 to 35 are based on the following passage: just seven years age, the jarvik-7 artificial heart was being cheered as the model of human creativeness.the sight of barney clark-alive and conscious after trading his diseased heart for a metal -and -plastic pump -convinced the press, the public and many doctors that the future had arrived. it hadn't .after monitoring production of the jarvik-7 , and reviewing its effects on the 150 or so patients (most of whom got the device as a temporary measure) the u.s. food and drug administration concluded that the machine was doing more to endanger lives than to save them. last week the agency cancelled its earlier approval, effectively banning the device.the recall may hurt symbion inc., maker of the jarvik-7, but it won't end the request for an artificial heart. one problem with the banned model is that the tubes connecting it to an external power source created a passage for infection . inventors are now working on new devices that would be fully placed, along with a tiny power pack, in the patient's chest. the first sample products aren't expected for another 10 or 20 years. but some people are already worrying that they'll work -and that america's overextended health-care programs will lose a precious $2.5 billion to $5 billion a year providing them for a relatively few dying patients. if such expenditures cut into funding for more basic care, the net effect could actually be a decline in the nation's health.31. according to the passage the jarvik-7 artificial heart proved to be _______.a)a technical failureb)a technical wonderc)a good life-saverd)an effective means to treat heart disease32.from the passage we know that symbion inc. _____.a)has been banned by the government from producing artificial heartsb)will review the effects of artificial hearts before designing new modelsc)may continue to work on new models of reliable artificial heartsd)can make new models of artificial hearts available on the market in 10 to 20 years33.the new models of artificial hearts are expected ______.a) to have a working life of 10 or 20 yearsb) to be set fully in the patient's chestc) to be equipped with an external power sourced) to create a new passage for infection34.the word "them" in line 7, para. 2 refers to _______.a)doctors who treat heart diseasesb)makers of artificial heartsc)america's health - care programsd)new models of artificial hearts35.some people feel that _______.a)artificial hearts are seldom effectiveb)the country should not spend so much money on artificial heartsc)the country is not spending enough money on artificial heartsd)america's health-care programs are not doing enough for the nation's healthpassage four questions 36 to 40 are based on the following passage: a rapid means of long-distance transportation became a necessity for the united states as settlement spread ever farther westward. the early trains were impractical curiosities, and for a long time the railroad companies met with troublesome mechanical problems. the most serious ones were the construction of rails able to bear the load, and the development of a safe, effective stopping system. once these were solved, the railroad was established as the best means of land transportation. by 1860 there were thousands of miles of railroads crossing the eastern mountainranges and reaching westward to the mississippi. there were also regional southern and western lines.the high point in railroad building came with the construction of the first transcontinental system. in 1862 congress authorized two western railroad companies to build lines from nebraska westward and from california eastward to a meeting point, so as to complete a transcontinental crossing linking the atlantic seaboard with the pacific. the government helped the railroads generously with money and land. actual work on this project began four years later. the central pacific company , starting from california, used chinese labor, while the union pacific employed crews of irish laborers .the two groups worked at remarkable speed, each trying to cover a greaterdistance than the other. in 1869 they met at a place called promontory in what is now the state of utah , many visitors came there for the great occasion. there were joyous celebrations all over the country , with parades and the ringing of church bells to honor the great achievement.the railroad was very important in encouraging westward movement. it also helped build up industry and farming by moving raw materials and by distributing products rapidly todistant markets. in linking towns and people to one another it helped unify the united states.36.the major problems with america's railroad system in the mid 19th century lay in ______.a)poor quality rails and unreliable stopping systemsb)lack of financial support for developmentc)limited railroad linesd)lack of a transcontinental railroad37. the building of the first transcontinental system _________.a)brought about a rapid growth of industry and farming in the westb)attracted many visitors to the construction sitesc)attracted laborers from europed)encouraged people to travel all over the country38. the best title for this passage would be _______.a)settlements spread westwardb)the coast-to -coast railroad: a vital linkc)american railroad historyd)the importance of trains in the american economy39.the construction of the transcontinental railroad took ______.a)9 yearsb)7 yearsc)4 yearsd)3 years40 . what most likely made people think about a transcontinental railroad?a) the possibility of government support for such a task.b) the need to explore utah.c) the need to connect the east coast with the west.d)the need to develop the railroad industry in the west.part iii

一，阅读：It was fifteen past nine as Marie hurried into the office building where she was going to work. Her bus had inched along through heavy morning traffic，making her a few minutes late for her very first job. She decided to start out half an hour earlier the next day.Once inside the lobby，she had to stand at the elevators and wait several minutes before she could get on one going to the sixth floor. When she finally reached the office marked “Smith Enterprises”， she knocked at the door nervously and waited. There was no reply. She tapped on the door again，but still there was no answer. From inside the next office，she could hear the sound of voices，so she opened the door and went in.Although she was sure it was the same office she had been in two weeks before when she had the interview with Mr. Smith， it looked quite different now. In fact，it hardly looked like an office at all. The employees were just standing around chatting and smoking. In the front of the room，somebody must have just told a good joke，she thought，because there was a loud burst of laughter as she came in. For a moment she had thought they were laughing at her.Then one of the men looked at his watch，clapped his hands and said something to the others. Quickly they all went to their desks and，in a matter of seconds，everyone was hard at work. No one paid any attention to Marie. Finally she went up to the man who was sitting at the desk nearest to the door and explained that this was her first day in the office. Hardly looking up from his work，he told her to have a seat and wait for Mr. Smith， who would arrive at any moment. Then Marie realized that the day…s work in the office began just before Mr. Smith arrived. Later she found out that he lived in Connecticut and came into Manhattan on the same train every morning，arriving in the office at 9∶35，so that his staff knew exactly when to start working.1． Marie felt nervous when she knocked at the door because______.［A］it was her first day in a new job［B］she was a little bit late for work［C］she was afraid that she had gone to the wrong place［D］there was no answer from inside the office2． Marie could hardly recognize the office she went into as______.［A］she had been there only once［B］Mr. Smith was not in the office［C］nobody was doing any work［D］the office had a new appearance3． The people in the office suddenly started working because______.［A］they saw a stranger in the office［B］their morning break was ended［C］no one wanted to talk to Marie［D］the boss was about to arrive4． We can infer from the text that the employees of the enterprise______.［A］would start their work by listening to a joke［B］were cold to newcomers［C］were always punctual for work［D］lacked devotion to the company5． The best title for this text would be______.［A］Punctual Like A Clock［B］A Cold Welcome［C］An Unpunctual Manager［D］Better Late Than Never写作第一部分：句型转换1.Many workers built this factory in 2001.This factory ___ ____ by many workers in 2001.2.
