Choose the one that you think is the best answer.TEXT AIf you like the idea of staying with with a family,living in house might be the answer.Good landladies---those who are superb cooks and launderers,are figures as popular in fiction as the bad ones who terrorize their guests and overcharge them at the slightest opportunity.The truth is probably somewhere between the two extremes.If you are lucky,the food will be adequate, some of your laundry may be done for you and you will have a reasonable amount of comfort and companionship .For the less fortunate ,house rules may restrict the freedom to invite friends to vistit,and shared cooking and bathroom facilities can be frustrating and row-provoking if tidy and untidy guests are living under the same roof.The same disadvantages can apply to flat sharing,with the added difficulties that arise from deciding who pays for what,and in what proportion.One person may spend hours on the phone,while another rarely makes calls. If you want privacy with a guest , how do you persuade the others to go out; how do you persuade them to leave you in peace,especially if you are student and want to study?Conversely,flat sharing can be cheap,there will always be someone to talk to and go out with,and the chores,in theory,can be shared.81.According to the passage ,landladies are ________ually strict.B.always mean.C.adequately competent.D.very popular with their guests.82.What is the additional disadvantage of flat sharing ?A.Problems of sharing and paying.B.Differences in living habits.C.Shared cooking and bathroom facilities.D.Restriction to invite friends to visit.83.What is NOT mentioned as a benefit of flat sharing?A.Rent is affordableB.There is companionship.C.Housework can be shared.D.There is peace and quiet.TEXT B(1) Travelling through the country a couple of weeks ago on business,I waslistening to the talk of the late UK writer Douglas Adams’ masterwork “The Hitchhiker’s Guide to the Galaxy” on the radio and thought-I know,I’ll pick up the next hitchhikers I see and ask them what the state of real hitching is today in Britain.(2)I drove and drove on main roads and side roads for the next few days and never saw a single one.(3)When I was in my teens and 20s ,hitchhiking was a main form of long-distance transport.The kindness or curiosity of strangers took me all over Europe,North America,Asia and southern Africa,Some of the lift-givers became friends ,many provided hospitality on the road.(4)Not only did you find out much more about a country than when traveling by train or plane ,but there was that element of excitement about where you would finish up that night.Hitchhiking featured importantly in Western culture.It has books and songs about it .So what has happened to it?(5)A few years ago ,I asked the same question about hitching in a column ofa newspaper.Hundreds of people from all over the world responded with their view on the state of hitchhiking .(6)Rural Ireland was recommended as a friendly place for hitching,as was Quebec,Canada-“if you don’t mind being criticized for not speaking French”.(7)But while hitchhiking was clearly still alive and well in some places ,the general feeling was that throughtout much of the west it was doomed.(8)With so much news about crime in the media,people assumed that anyone on the open road without the money for even a bus ticket must present a danger.But do we need to be so wary both to hitch and to give a lift?(9)In Poland in the 1960s,according to a Polish woman who e-mail me ,＂the authorities introduced the Hitchhiker’s Booklet.The booklet contained coupons for drivers,so each time a driver picked somebody ,he or she received a coupon.At the end of the season,drivers who had picked up the most hikers were rewarded with various prizes.Everyone was hitchhiking then”.(10)Surely this is a good idea for society.Hitchhiking would increase respect by breaking down barriers between strangers.It would help fight global warming by cutting down on fuel consumption as hitchhikers would be using existing fuels.It would also improve educational standards by delivering instant lessons in geography ,history,politics and sociology.(11)A century before Douglas Adams wrote his “Hitchhiker’s Guide”,another adventure story writer,Robert Louis Stevenson, gave us that what should be the hitchhiker’s motto:＂To travel hopefully is a better thing than to arrive.” What better time than putting a holiday weekend into practice. Either put it to the test yourself, or help out someone who is trying to travel hopefully with thumb outstretched.84. In which paragraph(s) does the writer comment on his experience of hitchhiking?A. (3)B. (4)C. (3) and (4)D. (4) and (5)85. What is the current situation of hitchhiking?A. It is popular in some parts of the world.B. It is popular throughout the west.C. It is popular only in the North Amercia.D.It’s still popular in Poland.86. What is the writer’s attitude towards the practice in Poland?A. Critical.B. Unclear.C. Somewhat favourable.D. Strongly favourable.87. The writer has mentioned all the following benefits of hitchhiking EXCEPTA. promoting mutual respect between strangers.B. increasing one’s confidence in strangers.C. protecting enviroment.D. enriching one’s knowledge.88.＂Either put it to the test yourself…”in Paragraph (11) meansA. to experience the hopefulness.B. to read Adams’ book.C. to offer someone a lift.D.to be a hitchhiker.TEXT CI am afraid to sleep. I have been afraid to sleep for the last few weeks. I am so tired that, finally, I do sleep, but only for a few minutes. It is not a bad dream that wakes me ; it is the realiry I took with me into sleep . I try to think of something else.Immediately the woman in the marketplace comes into my mind.I was on my way to dinner last night when I saw her . She was selling skirts. She moved with the same ease and loveliness I often saw in the women of Laos. Her long black hair was as shiny as the black silk of the skirts she was selling . In her hair, she wore three silk ribbons, blue ,green, and white. They reminded me of my childhood and how my girlfriends and I used to spend hours braiding ribbons into our hair.I don’t know the word for “ribbons”, so I put my hand to my own hair and , with three fingers against my head , I looked at her ribbons and said “Beautiful.”She lowered her eyes and said nothing. I wasn’t sure if she understood me (I don’t speak Laotian very well).I looked back down at the skirts. They had designs in them: squares and triangles and circles of pink and green silk. They were very pretty. I decided to buy one of those skirts, and I began to bargain with her over the price. It is the custom to bargain in Asia. In Laos bargaining is done in soft voices and easy moves with the sort of quiet peacefulness.She smiled, more with her eyes than with her lips. She was pleased by the fewwords I was able to say in her language, although they were mostly numbers, and she saw that I understood something about the soft playfulness of bargaining. We shook our heads in disagreement over the price; then, immediately, we made another offer and then another shake of the head. She was so pleased that unexpectedly, she accepted the last offer I made. But it was too soon. The price was too low. She was being too generous and wouldn’t make enough money. I moved quickly and picked up two more skirts and paid for all three at the price set; that way I was able to pay her three times as much before she had a chance to lower the price for the larger purchase. She smiled openly then, and, for the first time in months, my spirit lifted. I almost felt happy.The feeling stayed with me while she wrapped the skirts in a newspaper and handed them to me. When I left, though, the feeling left, too. It was as though it stayed behind in the marketplace. I left tears in my throat. I wanted to cry. I didn’t , of course.I have learned to defend myself against what is hard; without knowing it, I have also learned to defend myself against what is soft and what should be easy.I get up, light a candle and want to look at the skirts. They are still in the newspaper that the woman wrapped them in. I remove the paper, and raise the skirts up to look at them again before I pack them. Something falls to floor. I reach down and feel something cool in my hand. I move close to the candlelight to see what I have. There are five long silk ribbons in my hand, all different colours. The woman in the maketplace! She has given these ribbons to me!There is no defense against a generous spirit, and this time I cry, and very hard, as if I could make up for all the months that I didn’t cry.89.According to the writer, the woman in the marketplaceA refused to speak to her.B was pleasant and attractive.C was selling skirts ribbons.D recognized her immediately.90. Which of the following in NOT corret?A. The writer was not used to bargaining.B. People in Asia always bargain when buying things.C.

Why did the writer finally decide to buy three skirts?A.The skirts were cheap and pretty.B.She liked the patterns on the skirts.C.She wanted to do something as compensation.D.She was fed up with further bargainning with the woman.93.When the writer left the marketplace, she wanted to cry, but did not becauseA. she had learned to stay cool and unfeeling.B. she was afraid of crying in public.C.she had learned to face difficulties bravely.D. she had to show in public that she was strong.94. Why did the writer cry eventually when she looked at the skirts again?A.she suddently felt very sad.B.she liked the ribbons so much.C.she was overcome by emotion.D.she felt sorry for the woman.TEXT DThe kids are hanging out. I pass small bands of students, on my way to work these mornings.They have become a familiar part of the summer landscape.These kids are not old enough for jobs. Nor are they rich enough for camp. They are school children without school. The calendar called the school year ran out on them a few weeks ago. Once supervised by teachers and principals, they now appear to be “self care”.Passing them is like passing through a time zone. For much of our history, after all, Americans arranged the school year around the needs of work and family. In 19th century cities, schools were open seven or eight hours a day, 11 months a year.In rural America, the year was arranged around the growing season. Now, only 3 percent of families follow the agricultural model, but nearly all schools are scheduled as if our children went home early to milk the cows and took months off to work the crops. Now, three-quarters of the mothers of school-age children work, but the calendar is written as if they were home waiting for the school bus.The six-hour day, the 180-day school year is regarded as something holy. But when parents work an eight-hour day and a 240-day year, it means something different. It means that many kids go home to empty houses. It means that, in the summer, they hang out.“We have a huge mismatch between the school calendar and the realisties of family life,”says Dr. Ernest Boyer ,head of the Carnegie Foundation for the Advancement of Teaching.Dr. Boyer is one of many who believe that a radical revision of the school calendar is inevitable.＂School, whether we like it or not, is educational. It always has been.”His is not popular idea. Schools are routinely burdened with the job of solving all our social problems. Can they be asked to meet the needs of our work and family lives?It may be easier to promote a longer school year on its educational merits and, indeed, the educational case is compelling. Despite the complaints and studies about our kids’ lack of learning, the United State still has a shorter school year than any industrial nation. In most of Europe, the school year is 220 days. In Japan, it is 240 days long. While classroom time alone doesn’t produce a well-educated。

《基础会计》(简明版)(第3版)课后习题答案 07第七章 应用练习题参考答案与指导
第七章成本计算方法及其应用练习题参考答案与指导一、判断题答题要求：根据各题给出的说法判断正误，你认为正确的，在题后的括号中打“√”，你认为错误的打“×”。
1.成本计算是计算确定各计算对象总成本的一种专门方法。
( × )解题指导：成本计算不仅要计算各计算对象的总成本，还应计算其单位成本。
2.成本计算对象是指具体负担相应费用的材料和产品等。
( √ )解题指导：成本计算就是围绕材料和产品等具体对象而进行的，发生的各种支出相应地也由这些具体对象承担。
3.与材料采购有关的费用都要计入材料采购的成本。
( × )解题指导：根据重要性原理，有一部分与材料采购有关的费用，如材料采购人员的差旅费、发生的市内零星运费等，可不计入材料采购成本，而计入企业的管理费用。
4.将有关费用计入成本的方法有直接计入和间接计入两种。
( √ )解题指导：这是两种将有关费用计入成本计算对象成本的基本方法。
其中，直接计入的部分是指由某一成本计算对象独立承担的费用；间接计入的部分是指由多个成本计算对象共同承担的费用。
5.企业只能以月份为单位作为成本计算的周期。
( × )解题指导：在一般情况下，产品生产企业是以月份为单位作为成本计算周期的。
某些企业对于生产周期长的产品，也可以该产品的生产周期作为成本计算期。
6.材料采购过程中发生的共同性费用应分配计入材料采购成本。
( √ )解题指导：共同性费用往往是为同时购入多种材料而发生的，应分配计入材料采购成本。
7.产品生产过程中发生的制造费用应直接计入产品的生产成本。
( × )解题指导：在同时生产多种产品的情况下，制造费用也是为多种产品的生产而共同发生的，一般应分配计入产品生产成本，而不能直接计入产品的生产成本。
当然，如果企业只生产一种产品，那么发生的制造费用就应全部由该产品承担。
8.“完工产品成本计算表”是会计上的重要原始凭证。
( √ )解题指导：“完工产品成本计算表”是计算完工产品成本的专用表格，在会计上可以根据该表的计算结果进行完工产品验收入库的账务处理。
