Investors wanted to sell their shares before the stock lost value. Over the next 5 days millions of shares flooded the market. Many investors lost all their money.During 1920s many Americans had invested in the stock market (股票市场). Many got rich.In 1928. Herbert Hoover was elected president. He said the future was bright with hope.People were being advised to buy stock before prices climbed even higher. Common sense was in short supply. Stock market rules let investors buy shares even if they did not have enough money. That is still true today but there are stronger controls.During the summer of 1929，some economists warned that there was no real value behind the high prices. President Hoover urged stock market officials to make trading safer and more honest. But he did not think the government should interfere in the market.When the drop in stock prices finally came，it was slow at first. It picked up speed (加速) as investors sold more and more shares. Several bankers bought stocks in an effort to prevent a crash. But the intense activity continued. October 29 is remembered as Black Tuesday. That day alone，stocks lost a tenth of their value.The crash (暴跌) caused a lot of people to lose their jobs，their farms and their homes. Many banks and businesses failed. The crash led to a worldwide depression (萧条) .36. The reason for the Great Crash is .A. that millions of shares flooded the marketB. Herbert Hoover was elected presidentC. the future was bright with hopeD. people kept buying stock before prices climbed even higher37. The government was responsible for the Great Crash of 1929 because .A. it urged stock market officials to make trading safer and more honestB. it did not interfere in the marketC. investors sold shares even if they did not have enough moneyD. fear seized the New York Stock Exchange38.

Everyone seems to think that his native (本国) language is the most important one，as it is their first language. For many people it is even their only language all their lives. But English is the world's most widely used language.As a native language，English is spoken by nearly three hundred million people：in the U. S. ，England，Australia and some other countries.For people in India and many other countries，English is often necessary for business，education，information and other activities. So English is the second language there.As a foreign language，no other language is more widely studied or used than English. We use it to listen to the radio，to read books or to travel. It is also one of the working languages in the United Nations and is more used than the others.40. The native language is a person's language.A. firstB. onlyC. oneD. foreign41.

Questions 11～15 are based on the following passage:Scientists have tried to come up with biological explanations for the difference between boys and girls. However, none were believable enough to explain the general picture. As one scientist points out, "There are slight genetic (遗传的) differences between the sexes at birth which may affect the subjects boys and girls choose. But the difficulty is that by the time children reach school age, there are so many other effects that it is almost impossible to tell whether girls are worse at science and math, or whether they've been brought up to think of these subjects as boys “…territory‟”Statistics show that in mathematics, at least, girls are equal to boys. A recent report suggests that girls only stop studying mathematics because of social attitudes. One of the reports' authors says, “While it is socially unacceptable for people not to be able to read and write, it is still acceptable for women to say that they are' hopeless, at math. Our research shows that, although girls get the explanation for the difference, which is very clear during the teenage years goes as far back as early childhood experiences.”From their first days in nursery school, girls are not encouraged to work on their own or to complete tasks, although boys are. For example, boys and girls are often asked to “help” with repair work. This en couragement leads to a way of learning how to solve problems, later in life. Evidence shows that exceptional mathematicians and scientists did not have teachers who supplied answers; they had to find out for themselves. A further report on maths teaching shows that teachers seem to give more attention to boys than to girls.Most teachers who take part in the study admitted that they expect their male students to dobetter at mathematics and science subjects than their female students. All of this tends to encourage boys to work harder in these subjects, gives them confidence and makes them believe that they can succeed.Interestingly, both boys and girls tend to regard such "male" subjects like mathematics and science as difficult. Yet it has been suggested that girls avoid mathematics courses, not because they are difficult, but for social reasons.Mathematics and science are mainly male subjects, and therefore, as girls become teenagers, they are less likely to take t hem up. Girls do not seem to want to be in open competition with boys. Neither do they want to do better than boys because they are afraid to appear less female and so, less attractive.11. The underlined word" territory" in the first paragraph most probably means .A. special fieldB. interestC. the landD. map12. According to scientific study, .A. math is not fit for girls to studyB. boys have a special sense of mathC. girls are poorer at math because they are the weaker sexD. girls can learn math as well as boys if given enough encouragement13. Those who made extraordinary contribution in mathematics and science .A. usually had good teachers to help themB. had the abilities to solve problems by themselvesC. usually worked harder than othersD. were encouraged to repair things when young14. Which of the following is NOT true according to the text?A. It is a social problem rather than a problem of brains that girls are poor at math.B. It seems socially acceptable for a girl not to be able to read and write.C. It is not easy for boys and girls to learn math and science.D. There is no connection between a girl's beauty and her ability.15. The best headline for the passage is .A. Are boys cleverer than girlsB. Who's afraid of scienceC. Girls are poorer at math than boys at math,D. Mat h－A Difficult SubjectQuestions 16～20 are based on the following passage:It was Monday. Mrs. Smith's dog was hungry, but there was not any meat in the house.Considering that there was no better way, Mrs. Smith took a piece of paper, and wrote the following words on it: “Give my dog half a pound of meat.” Then she gave the paper to her dog and said gently: “T ake this to the butcher, and he's going to give you your lunch today.”Holding the piece of paper in its mouth, the dog ran to the butcher's. It gave the paper to the butcher. The butcher read it carefully, recognized that it was really the lady's handwriting and soon did it as he was asked to. The dog was very happy, and ate the meat up at once.At noon, the dog came to the shop again. It gave the butcher a piece of paper again. After reading it, he gave 'it half a pound of meat once more.The next day, the dog came again exactly at noon. And as usual, it brought a piece of paper in the mouth. This time, the butcher did not take a look at paper, and gave the dog its meat, for he had regarded the dog as one of his customers (*people who buy sth. from a shop).But, the dog came again at four o'clock. And the same thing happened once again. To the butcher's more surprise, it came for the third time at six o'clock, and brought with it a third piece of paper. The butcher felt a bit puzzled. He said to himself, “This is a small dog. Why does Mrs Smith give it so much meat to eat today?”.Looking at the piece of paper, he found that there were not any words on it!16. Mrs. Smith treated her little dog quite .A. cruellyB. fairlyC. kindlyD. friendly17. It seemed that the dog knew well that the paper Mrs. Smith gave it .A. might do it much harmB. could do it much goodC. would help the butcherD. was worth many pounds18.

From its experience, the dog found that .A. only the paper with Mrs. Smith's words in it could bring it meatB. the butcher would give the meat to it whenever he saw itC. Mrs. Smith would pay for the meat it got from the butcherD. a piece of paper could bring it half a pound of meat20. At the end of the story, you'll find thatA. the dog was clever enough to write on the paperB. the dog dared not go to the butcher's any moreC. the butcher was told not to give any meat to the dogD. the butcher found himself cheated (*act in a way that is not honest) by the cleveranimalQuestions 21～25 are based on the following passage:Everything living on eart h－each plant and anima l－needs other living things. Nothing lives alone. Most animals must live in a group, and even a tree or a plant grows close together with others of the same kind. Sometimes one living thing hunts another, one eats and the other is eaten. Each kind of life eats another kind of life in order to live, and together they form a food chain (食物链). Some food chains are simple, others are complicated (复杂). But all have two things in commo n－all food chains begin with the sun, and all food chains become broken up if one of the links disappears.All, life depends on energy from sunlight. Only plants can use this energy directly. Their leaves are little factories that use sunlight to make food from water and things in the soil and air.Plants in turn feed all other living things. Animals can only use the sun's energy after it has been changed into food by plants. Some animals feed directly on plants, others eat smaller animals. Meat-eating animals are only eating plants indirectly.What about human beings? We are members of many food chains. We eat wheat, rice, vegetables, fruit and so on We also eat meat and drink milk. This means the sun's energy passes through plant to animal before it reaches us.Nature is a greater thing. Any food chain always produces enough for each of its members if it is left alone. When there isn't enough food for any link in the chain, some of its members die off. So the balance is always kept.But men in their greed(贪婪) and ignorance(无知) often break up the food chain and do great harm not only to one plant or animal, but to all the links in the chain. People make seas and rivers dirty. They destroy whole forests and kill many kinds of wild animals and birds. When a river becomes dirty, the fish cannot be eaten. Men eat the fish and get strange diseases. In some places men have no fish to eat any more, because the fish have died off. Each form of life is linked to all others. Breaking the links puts all life in danger.21. How does everything living on earth live?A. Each plant can live alone.B. Each animal can live alone.C. Everything living on earth can not live without needing other living things.D. If living things want to live they must kill each other.22. How is food for plants made? Food for plants is made .A. from waterB. from the air in the skyC. from the soilD. from water, things in the soil and air, sunlight23. How do all food chains break? All food chains are broken if .A. one kind of animal is eaten upB. one kind of plant is destroyedC. one kind of animal eats anotherD. one of the links is destroyed24. Which living things can use energy directly?A. Animals.B. Plants.C. Both animals and plants.D. All living things.25. Why is all life in danger? Because break up the food chains.A. human beingsB. animalsC. plants and animalsD. man and wild animalsQuestions 26～30 are based on the following passage:The whole body is covered with skin. The surface of the skin is dead (like the hair and the nails) , but it is made from a living layer(层) just under the surface. The outside dead layers wear off(磨损)all the time, with new ones replacing them, and the body forms a totally' new skin every three weeks.The skin protects the body from the outside world and it passes information, from the outside. It helps to keep water in the body and to keep the body at the same temperature. Bacteria (细菌) can't get in through the skin unless it is damaged.If the weather is cold, the blood vessels (血管) in the skin squeeze down, or contract (收缩) ,so that as little blood as possible comes near the surface. This means that less warmth is lost to the outside, This makes the ski1 look pale, or even “blue”. At the same time, the hairs on the skin are pulled upright by tiny muscles.When it is hot, the blood vessels expand (扩大),or get wider again, to allow plenty of blood to run near the surface of the skin. This helps the body to lose heat, and the skin may look red At the' same time, the sweat glands (汗腺)produce more sweat, which cools the skin.If your skin has ever been numb (麻木的), you will realize how important the feeling from the skin is. Nerves (神经) in the skin are sensitive(敏感的) to heat and cold, sharpness, hardness and softness, wetness and dryness and pain. If one is not able to feel these things, which can act as warnings, he is likely to be burned, cut or hurt in other ways.The colour of the skin depends on special colour cells (细胞). These are just below the top layers of the skin. They are needed as protection from some harmful ray of the sun. People with pale skins may “tan” (晒黑)in the sun.

东北农业大学网络教育学院成本会计高升专作业题答案
东北农业大学网络教育学院成本会计高升专作业题答案作业题一答案一、名次解释1、生产经营费用：是指企业再生产经营过程中发生的各种劳动耗费，包括直接用于产品消耗的生产费用、管理费用、财务费用、销售费用等。
2、资本性支出：是指通过它所取得的财产或劳务的效益，可以给予多个会计期间所发生的那些支出。
因此，这类支出应予以资本化，先计入资产类科目，然后，再分期按所得到的效益，转入适当的费用科目。
3、费用要素：工业企业发生的各种费用按其经济内容划分，主要有劳动对象方面费用、劳动手段方面费用和活劳动方面费用，这三大费用构成费用要素。
费用要素具体划分为八类，分别为1．外购材料；2．外购燃料；3．外购动力；4．职工薪酬；5．折旧费；6．利息费用及折旧；7．税金；8．其他支出。
费用要素一个突出的特点是其在经济用途上没有方向性。
4、计划成本分配法是指在分配辅助生产费用时，按辅助生产车间提供的产品或劳务的计划单位成本和各受益单位的实际耗用量计算各受益单位应负担的辅助生产费用的一种辅助生产费用分配方法。
根据辅助生产车间提供的产品、劳务数量及其计划单位成本，计算为各车间、部门提供服务的产品和劳务数量应分配的费用。
对辅助生产车间发生的实际成本与按计划成本计算的分配额之间的差额，为了简化核算，可不再按受益比例进行分摊，而直接增加或冲减制造费用或管理费用。
5、制造费用包括产品生产成本中除直接材料和直接人工以外的其余一切生产成本制造费用，主要包括企业各个生产单位（车间、分厂）为组织和管理生产所发生的一切费用。
6、分批法是按照产品批别归集生产费用、计算产品成本的一种方法。
在小批单件生产的企业中，企业的生产活动基本上是根据定货单位的订单签发工作号来组织生产的，按产品批别计算产品成本，往往与按定单计算产品成本相一致，因而分批法也叫定单法。
7、逐步结转分步法也称顺序结转分步法，它是按照产品连续加工的先后顺序，根据生产步骤所汇集的成本，费用和产量记录，计量自制半成品成本，自制半成品成本随着半成品在各加工步骤之间移动而顺序结转的一种方法。
东北农业大学网络教育学院 成本会计高升专作业题
东北农业大学网络教育学院成本会计高升专作业题作业题（一）一、名词解释1.生产经营费用：根据生产经营费用(即成本和费用)的特点、核算与管理的要求，可以按照不同的标准分类。
2.资本性支出：资本性支出是指通过它所取得的财产或劳务的效益，可以给予多个会计期间所发生的那些支出。
3.费用要素：是指工业企业发生的各种费用按其经济内容划分，主要有劳动对象方面费用、劳动手段方面费用和活劳动方面，这三大费用构成的要素。
4.辅助生产费用的计划成本分配法：指企业在生产经营过程中，按照既定的成本费用目标，对构成成本费用的诸要素进行的规划、限制和调节，及时纠正偏差，控制成本费用超支，把实际耗费控制在成本费用计划范围内。
其控制的内容包括材料消耗成本控制、工资成本控制、费用成本控制。
5.制造费用：企业为生产产品和提供劳务而发生的各项间接成本。
企业应当根据制造费用的性质，合理地选择制造费用分配方法。
6.分批法：分批法是按照产品批别归集生产费用、计算产品成本的一种方法。
在小批单件生产的企业中，企业的生产活动基本是根据定货单位的订单签发工作号来组织生产的，按产品批别计算产品成本，往往与按定单计算产品成本相一致，因而分批法也叫订单法。
7.逐步结转分步法：产品成本计算分步法中结转成本的一种方法，亦称“计划半成品成本法”。
8.定额法：定额法就是指用一定的金额投资股票和债券并使这二项的资金保持一定比例的投资方法。
就是为了及时地反映和监督生产费用和产品成本脱离定额的差异，加强定额管理和成本控制而采用的一种成本计算方法。
9.成本报表：成本报表是用以反映企业生产费用与产品成本的构成及其升降变动情况，以考核各项费用与生产成本计划执行结果的会计报表，是会计报表体系的重要组成部分，成本报表资金耗费和产品成本及其升降变动情况，用以考核成本计划执行结果。
10.成本分析：是利用成本核算及其他有关资料，分析成本水平与构成的变动情况，研究影响成本升降的各种因素及其变动原因，寻找降低成本的途径的分析方法。
