蓝鸽10级第二阶段-作业全部参考答案
作文：1. For this part, you are allowed 30 minutes to write a composition on the topic " Should One Own a Car?". The beginning of each paragraph is given. Your part of writing should be no less than 120 words.1. Car is very important nowadays in our life….2. There are, on the other hand, many good reasons against having a car….3. In my opinion,…Car is very important nowadays in our life.In Spain every family has a car. but sometimes these families have more than one car. In consequence, it suposes more ecologycal problems. In fact, there are a lot of arguments for and against or having a car.One of the strongest arguments against having a car is the ecologycal problem that is produced by this transport. Pollution is increasing and petroil is decreasing more every year in the world.Furthermore, to drive a car suposes to spend a lot of time and to respect the rules, and if there is a lot of traffic you must wait.There are, on the other hand, many good reasons against having a carthere are several arguments for having a car. Firstly, if you have this vehicle you have also more freedom because you don’t depend on public transport and its timetable. Secondly, you can travel and go wherever you want and the cost of this trip will not be so expensive as travelling by plane. Thridly, for a family of medium class the cost of having a car is better than the cost of paying a different transport for every trip. Finally, if you have an emergency you can drive your car and to solve your problem.In my opinion, the fact of having a car is very important in our society, aulthough it would be necessary that all the families wich have more than one car, they should think in the possibility of use pulic transport. On balance, nowadays there are more people that has started to use gasoil (a product that can sustitute petroil).2. For this part, you are allowed 30 minutes to write a composition on the topic "SHOULD EXAMINATION BE ABOLISHED". Your composition should be based on your own understanding of the topic and it should be no less than 120 words.As we know that the examination system has come to be the main theme of modern education. Every one from his early child-hood should take endless examinations and succeed in passing them, before he could graduate from a college or university. As much importance has been attached to it in schooleducation, it has been subjected to mounting criticism as to its validity. People in favor of it praise this system to great extent; and those oppos-ing to it maintain that such a system should be abolished.A lot of people think that the examination system should be abolished. In the first place, because of the existence of the exami-nation system, students go out for gaining high marks so that they often forget the main purpose of education. Many so-called "clever" students are nothing but bookworms who merely know the skeleton of knowledge. The aim of education is to enablestu-dents to learn how to live, how to work, and how to contribute to the country with their expertise. To do this, the students must re-ceive training, in physical as well as mental areas. But the present examination system has discouraged students from making such an attempt.To summarize, I really think that the examination system should be further improved instead of being abolished. Hopefully, one day we can study for our ideals without great pressure. And if that is so, I can definitely see a bright future ahead out there wait-ing for us anxiously !阅读：1.[A] very serious2.[C] hardly care about law and order3.[D] stealing sweets from a chain store was illegal4.[C] they have enough money to buy them5.[D] both A and C6.[A] know very well what crime is7.[A] severe punishment once used in the past8.[D] she went to school in Denmark9.[C] It was rather cold.10.[A] complain angrily when handling our luggage11.[B] They had to buy new furniture.12.[A] To learn more English.13.[A] are fond of having anything but meaningless conversations14.[B] boring15.[D] good manners are very important to everyone16.[B] since before the time of Christ17.[B] among people living close together18.[C] was not to break out again19.[C] fifteen million people20.[A] the virus could not be found and vaccine developed21.[A] a good international reporting system22.[D] they change their nature quickly23.[B] worldwide health organizations24.[C] Soldier Sickness25.[D] people who have a lot of free time26.[A] are in great demand27.[D] expensive28.[B] exercise29.[C] want to keep fit30.[B] running energetically31.[C] to show people's interest in exercise32.[A] did not like any kind of sports33.[B] vague about his own attitude34.[A] drought35.[B] ruined36.[B] the river could be used for irrigation37.[C] doubtful38.[C] Tom was an outsider who had learned farming from books39.[D] they should buy the new fertilizer with vitamin40.[D] the water-wagon was once used by a college to carry water41.[D] none of the above42.[C] were bent and twisted but not damaged43.[B] reading more wisely44.[D] hinders reading efficiency45.[C] to understand meaning46.[C] not absolutely essential to the grasp of meaning47.[C] point at key words48.[C] a textbook49.[C] reduces the death rate in traffic accidents50.[B] make the front seat children under 14 wear a seat belt51.[B] Someone who is picking up the children from the local school.52.[C] to get a valid medical certificate before wearing a seat belt53.[B] The Buildings Designed by the Greatest Architect Frank Lloyd Wright54.[B] beautiful in design and practical in use55.[A] It hadn't formed its own style yet.56.[C] architectural design should match natural surroundings57.[D] The houses are characterized by lines similar to those on the grassland.58.[B] promoting their physical and mental health59.[C] providing ideas that help in recovering the lost memory60.[B] find it difficult sometimes to deal with matters calmly61.[D] By ignoring them and talking about something else.62.[C] helping them to revive old memories63.[A] the presence of religious institutions64.[B] It is not clearly told in the passage.65.[B] Time and Culture.66.[D] All of the above.67.[C] people of different generations may have different views towards life, work and play68.[D] Both A and C.69.[D] the government would have funds to work for the welfare of people70.[A] protect persons and property71.[C] Everyone has his right to make a decision on the matter.72.[C] the government had to pay all kinds of costs73.[A] life insurance isn't fun to buy74.[A] many people prefer not to confront the subject75.[D] You should believe in either your agent only or those empirical estimates.76.[A] either you or your family might suffer77.[D] All of the above.78.[D] 9 years79.[C] Rome80.[D] people who compete in the games81.[B] Sir Ludwig Guttmann is an injured soldier.82.[D] in favor of holding the games for the disabled83.[D] planning our time scientifically84.[A] Americans are forced to be efficient against their will85.[C] Speeded-up work efficiency.86.[B] were able to act of our own free will87.[A] a slow-moving person88.[B] the role of spelling in general language development89.[D] to avoid using words one is not sure of90.[B] teachers will have less trouble in correcting mistakes91.[D] careless92.[D] the relationship between spelling and the content of a composition客观题21~5 DACCC 6~10 BCCDC11~15 AACAA 16~20 CAACC21~25 AAACD 26~30 CCABC翻译题1.美国一直是个单一的经济体，没有限制贸易的法规，这一事实也促成了这种一体性。

The former group of people think that pets are good and helpful companions. Some of them even go so far as saying that animals are also human, and their rights should be respected. Those who hate pets say that animals are noisy, dirty and dangerous. They think laws should be made to forbid people to keep dogs and cats in cities and towns. The different opinions on keeping pets, which reflect personal preferences, have caused many disputes and much unpleasantness among people who are close neighbors.Personally I do not like pets. But I think we should learn to respect the rights of pet lovers. We have no right to forbid people to keep pets in their homes, as long as the animals are properly taken care of and do not threaten the safety and peace of others.翻译【作业要求】:单句翻译（英译汉）Directions:In this section you are required to translate some English sentences into Chinese.

Each statement contains information given in one of the paragraphs. Identify the corresponding letter to the paragraph from which the information is derived. You may choose a paragraph more than once.The Peak Time For EverythingA）Could you pack more into each day if you did everything at the optimal time? A growing body of research suggests that paying attention to the body clock, and its effects on energy and alertness, can help pinpoint the different times of day when most of us perform our best at specific ta sks, from resolving conflicts to thinking creatively.1. Keep pace with natural rhythms.B) Most people organize their time around everything but the body's natural rhythms. Workday demands, commuting, social events and kids' schedules frequently dominate -- inevitably clashing with the body's circadian(生理节奏的) rhythms of waking and sleeping.C）Disruption of circadian rhythms has been linked to such problems as diabetes, depression, dementia（痴呆）and obesity, says Steve Kay, a professor of molecular and computational biology at the University of Southern California. When the body's master clock can synchronize functioning of all its metabolic（新陈代谢的）, cardiovascular and behavioral rhythms in response to light and other natural stimuli, it 'gives us an edge in daily life,' Dr. Kay says.D）When it comes to doing cognitive work, for example, most adults perform best in the late morning, says Dr. Kay. As body temperature starts to rise just before awakening in the morning and continues to increase through midday, working memory, alertness and concentration gradually improve. Taking a warm morning shower can jump-start the process. E）The ability to focus and concentrate typically starts toslide soon thereafter. Most people are more easily distracted from noon to 4 p.m., according to recent research led by Robert Matchock, an associate professor of psychology at Pennsylvania State University. Alertness tends to slump after eating a meal, Dr. Matchock found. Sleepiness also tends to peak around 2 p.m., making that a good time for a nap, says Martin Moore-Ede, chairman and chief executive of Circadian,a Stoneham, Mass., training and consulting firm.2. Make good use of fatigue.F) Surprisingly, fatigue may boost creative powers. For most adults, problems that require open-ended thinking are often best tackled in the evening when they are tired, according to a 2011 study in the journal Thinking & Reasoning. When 428 students were asked to solve a series of two types of problems, requiring either analytical or novel thinking, their performance on the second type was best at non-peak times of day when they were tired, according to the study led by Mareike Wieth, an assistant professor of psychological sciences at Albion College in Michigan. (Their performance on analytical problems didn't change over the course of the day.) Fatigue, Dr. Wieth says, may allow the mind to wander more freely to explore alternative solutions.G) Of course, everyone's body clock isn't the same, making it even harder to synchronize natural rhythms with daily plans. A significant minority of people operate on either of two distinctive chronotypes, research shows: Morningpeople tend to wake up and go to sleep earlier and to be most productive early in the day. Evening people ten d to wake up later, start more slowly and peak in the evening.3. Attach great importance to communication online.H) Communicating with friends and colleagues online has its own optimal cycles, research shows. Sending emails early in the day helps beat the inbox rush; 6 a.m. messages are most likely to be read, says Dan Zarrella, social-media scientist for HubSpot, a Cambridge, Mass.I) Reading Twitter at 8 a.m. or 9 a.m. can start your day ona cheery note. That's when users are most likely to tw eet upbeat, enthusiastic messages, and least likely to senddownbeat tweets steeped in fear, distress, anger or guilt, according to a study of 509 million tweets sent over two years by 2.4 million Twitter users, published last year in Science. One likely factor? 'Sleep is refreshing' and leaves people alert and enthusiastic, says Michael Walton Macy, a sociology professor at Cornell University and co-author of the study. The cheeriness peaks about 1-1/2 hours later on weekends -- perhaps because people are sleeping in, Dr. Macy says.J) Other social networking is better done later in the day. If you want your tweets to be re-tweeted, post them between 3 p.m. and 6 p.m., when many people lack energy to share their own tweets and turn to relaying other s' instead, Mr. Zarrella says. And posts to Facebook at about 8 p.m. tend to get the most 'likes,' after people get home from work or finish dinner. At that time of day, they're likely to turn to Facebook feeling less stressed. 'You have less stuff to do a nd more time to give,' says Mr. Zarrella.K) Late-night drama can be found on Twitter, where emotions heat up just before bedtime, between 10 p.m. and 11 p.m., says Scott Andrew Golder, a Ph.D. candidate at Cornell University and co-author of the Twitter study. At that time, people tended to send more emotion-laden tweets, both positive and negative. Tired out by the workday, but also freed from its stresses and demands, people become 'more alert and engaged, but also more agitated,' Dr. Macy says.4. Choose the right exercise time.L) When choosing a time of day to exercise, paying attention to your body clock can also improve results. Physical performance is usually best, and the risk of injury least, from about 3 p.m. to 6 p.m., says Michael Smol ensky, an adjunct professor of biomedical engineering at the University of Texas, Austin, and lead author with Lynne Lamberg of 'The Body Clock Guide to Better Health.'M) Muscle strength tends to peak between 2 p.m. and 6 p.m. at levels as much as 6% ab ove the day's lows, improving your ability to grip a club or racquet. Another boost for physical strength comes from the lungs, which function17.6% more efficiently at 5 p.m. than at midday, according toa study of 4,756 patients led by Boris Medarov, an assistant professor of medicine at Albany Medical College in New York. N) Eye-hand coordination is best in late afternoon, making that a good time for racquetball or Frisbee. And joints and muscles are as much as 20% more flexible in the evenin g, lowering the risk of injury, Dr. Smolensky says. These body rhythms hold true regardless of how much you've slept or how recently you've eaten.1. Due to different body clocks, people may feel it difficult tolans. [16].【参考答案】：Gphysical rhythms.

[题数:10;分数:30分;参考时间:20分0秒]Passage 1The fridge is considered anecessity. It has been so since the1960s when packaged food firstappeared with the label: "store inthe refrigerator".26. The statement "In myfridgeless Fifties childhood, I wasfed well and healthily." suggeststhat ____.In my fridgeless Fifties childhood, I was fed well and healthily. The milkman came daily, the grocer, the butcher, the baker, and the ice-cream man delivered two or three times a week. The Sunday meat would last until Wednesday and surplus (剩余) bread and mild became all kinds of cakes. Nothing was wasted, and we were never troubled by rotten food. Thirty years on, food deliveries have ceased, fresh vegetables are almost unobtainable in the country.The invention of the fridge contributed comparatively little to the art of food preservation. A vast way of well-tried techniques already existed - natural cooling, drying, smoking, sugaring, bottling ...What refrigeration did promote was marketing - marketing hardware and electricity, marketing soft drinks, marketing dead bodies of animals around the globe in search of a good price. Consequently, most of the world's fridges are to be found, not in the tropics where they might prove useful, but in the wealthy countries with mild temperatures where they are climatically almost unnecessary. Every winter, millions of fridges hum away continuously, and at vast expense, busily maintaining anartificially-cooled space inside an artificially-heated house - while outside, nature provides the desired temperature free of charge. The fridge's effect upon the environment has been evident, while[A] the author was well-fedand healthy even without a fridge in his fifties[B] the author was notaccustomed to using fridges even in his fifties[C] there was no fridge in the author's home in the 1950s[D] the fridge was in its early stage of development in the 1950s 【参考答案】：C27. Why does the author say that nothing was wasted before the invention of fridges?____[A] People would not buy more food than was necessary.[B] Food was delivered to people two or three times a week.[C] Food was sold fresh and did not get rotten easily.[D] People had effective ways to preserve their food.【参考答案】：D28. Who benefited the least from fridges according to theauthor?____its contribution to human happiness has been insignificant. If you don't believe me, try it yourself, invest in a food cabinet and turn off your fridge next winter. You may miss the hamburgers, but at least you'll get rid of terrible hum.[A] Inventors.[B] Consumers.[C] Manufactures.[D] Traveling salesmen.【参考答案】：B29. Which of the following phrases in the fifth paragraph indicates the fridge's negative effect on the environment?____[A] "Hum away continuously".[B] "Climatically almost unnecessary".[C] "Artificially-cooled space".[D] "With mild temperatures". 【参考答案】：A30. What is the author's overall attitude toward fridges?____[A] Neutral.[B] Critical.[C] Objective.[D] Compromising.【参考答案】：BPassage 2Status is a marvelous human invention that enables us to get along with one another and to determine where we "fit" in society. As we go about our everyday lives, we mentally attempt to place people in terms of their status. For example, we must judge whether the person in the library is a reader or a librarian, whether the telephone caller is a friend or a salesman, whether the unfamiliar person on our property is a thief or a meter reader, and so on.The status we assume often varies with the people we encounter, and changes throughout life. Most of us can. at very high speed, assume the status with various requirements. Much of social interaction consists of identifying and selecting among appropriate status and allowing other people to assume their status in relation to us. This means that we fit our actions to those of other people based on a constant mental process of appraisal and interpretation. Although some of us find the task more difficult than others, most of us perform it rather effortlessly.Status has been compared to ready-made clothes. Within certain limits, the buyer can choose style 31. In the first paragraph, the writer tells us that status can help us ____.[A] determine whether a person is fit for a certain job[B] behave appropriately in relation to other people[C] protect ourselves in unfamiliar situation[D] make friends with other people【参考答案】：B32. According to the writer, people often assume different status ____.[A] in order to identify themselves with others[B] in order to better identify others[C] as their mental processes change[D] as the situation changesand fabric. But an American is not free to choose the costume (服装) of a Chinese peasant or that of a Hindu prince. We must choose from among the clothing presented by our society. Furthermore, our choice is limited to a size that will fit, as well as by our pocketbook (钱包). Having made a choice within these limits we can have certain alterations made. but apart from minor adjustments, we tend to be limited to what the stores have on their racks. Status too comes ready made. and the range of choice is limited. 【参考答案】：D33. The word "appraisal" most probably means "____".[A] involvement[B] appreciation[C] assessment[D] presentation【参考答案】：C34. In the last sentence of the second paragraph, the pronoun "it" refers to "____".[A] fitting our actions to those of other people appropriately[B] identification of other people's statuses[C] selecting one's own statuses[D] constant mental process 【参考答案】：A35. By saying that "an American is not free to choose the costume of a Chinese peasant or that of a Hindu prince", the writer means ____.[A] different people havedifferent styles of clothes[B] ready-made clothes mayneed alterations[C] status come ready madejust like alterations[D] our choice of status islimited【参考答案】：D听短文Directions:In this section, you will hear 3 short passages.

All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be written down. Those sounds, whether spoken or written in letters, we call words.The power of words, the n, lies in their associati ons —the things they bring up before our min ds.Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increases.Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. This charming and effective use of words is what we call literary style. Above all, the real poet is a master of words. He can convey his meaning in words which sing like music, and which by their position and association can move men to tears. We should, therefore, learn to choose our words carefully and use them accurately, or they will make our speech silly and vulgar （粗俗）.The origin of language is ____________ .所选答案： B. a matter that is hidden or secret问题33 得 2 分，满分 2 分One of the reasons why men invented certain sounds to express thoughts and actions was that _________________________ .所选答案： C. they could communicate with each other问题34 得 2 分，满分 2 分The real power of words exists in their ______________ .D. representative function所选答案：问题35 得 2 分，满分 2 分Which of the following statements about great writers is NOT TRUE所选答案： C.

This difference set Alfred Wegener, a young geologist, inthinking. He thought the error too great to be reasoned out easily. Wegener himself took measurements and found that since 1869 the island had moved an additional five eighths of a mile. After checking the positions of other arctic land masses, he concluded that all of them were drifting westward at different speeds. From such date, Wegener developed his floating continents theory. He pictured in mind an original supercontinent that hardened out of molten material maki ng up the n ewbor n earth; even tually the mass cracked and broke in to several pieces —the present continents. The continents do seem to fit together like pieces of a puzzle, andfurthermore, some of the mountain ranges of different continents line up rather well, as if the land masses were at one time linked. As convincing as Wegener 's argument appeared, many geologists refused to accept it, and there was heated argument. Exactly how the continents were formed is still a leading geophysical mystery, though today many geophysicists are returning to the continental drift theory.The 1869 map indicated that _____________ .所选答案： A.
