治安管理处罚法的考题

治安管理处罚法的考题

治安管理处罚法的考题英文回答:The Law on Administration of Public Security Punishments, also known as the Public Security Administration Punishment Law, is an important legal framework in China that regulates the maintenance of public order and the punishment of violators. As a citizen of China, I am familiar with this law and its provisions.One of the key aspects of this law is the establishment of various administrative penalties that can be imposed for offenses related to public security. These penalties include warnings, fines, detention, and even the revocation of licenses or permits. For example, if someone is caught engaging in illegal gambling activities, they may be fined a certain amount of money or even detained for a period of time.Another important provision of the law is the powergiven to public security organs to enforce these penalties. Public security organs have the authority to investigate, collect evidence, and impose punishments on individuals who violate public security regulations. For instance, if someone is caught stealing, the police have the right to investigate the case, gather evidence, and then impose an appropriate punishment.The law also provides guidelines for the procedures and rights of individuals who are subjected to administrative punishments. It ensures that individuals have the right to defend themselves, present evidence, and appeal against the decision. This ensures that the punishment is fair and just. For instance, if someone is accused of a crime, they have the right to hire a lawyer to defend their case and present evidence to prove their innocence.Furthermore, the law also emphasizes the importance of education and rehabilitation. It encourages public security organs to provide guidance and education to individuals who have committed offenses, in order to help them understand the consequences of their actions and prevent them fromreoffending. For example, if someone is caught vandalizing public property, they may be required to attend educational programs or community service to learn about the importance of respecting public spaces.Overall, the Law on Administration of Public Security Punishments plays a crucial role in maintaining socialorder and ensuring the safety and well-being of citizens in China. It provides a legal framework for the punishment of public security offenses and promotes fairness and justicein the enforcement of these penalties.中文回答:治安管理处罚法,也被称为公安管理处罚法,是中国的一项重要法律框架,用于规范公共秩序的维护和违法者的惩罚。

(15 points)Read Passage 1 and then answer Questions 16-20 briefly. Write your answers on the Answer Sheet.Passage 1In Australian families the central relationship is usually that between husband and wife, with children being thought of as independent individuals from an early age. The central relationship around which Chinese families revolve is quite different. Here the stress is placed on the relationship between parents and children. Couples with children view the roles of mother acid father as coming before those of husband and wife. It is the parents, usually the father, who make all important decisions for children. It is the father, for example, who will usually make decisions concerning what and where the children should study. This is in marked contrast to Australian families where children play an increasingly important role in deciding such matters as they grow older. This independence is also shown in the Australian custom of children leaving home to live independently of their parents long before marriage. There are few if any opportunities for young people to set up independently in this fashion in China. Indeed, the Australian practice in this regard can seem from a Chinese perspective to indicate that Australians do not care about their families.Australian children are more likely to be expected to work while they are studying than their Chinese counterparts. This can also apply to household chores, with Chinese parents expecting their offspring to devote their time to their studies. Children may be excused such duties right up to marriage, so that married life can sometimes come as a rude awakening to the need to cook and clean. Whereas in Australia students may work during the holidays or part-time during term, such activity is rare in China. The situation has changed somewhat since the end of the 1980s, with some students taking work as tutors or providing various services such as dressmaking. But the initial public reaction was one of shock. It is, then, still viewed as primarily the parents’ responsibility to support their children while they are pursuing their education. Money spent in this way is under no circumstances regarded as a loan, to be repaid when the children finish their education and have secured a job. University students in Australia also receive financial assistance from their parents and there is in some families an understanding that this will be repaid once they are financially independent. To many Chinese this may smack of lack of love and family feeling.The Australian emphasis on fostering independence in children from an early age runs counter to the Chinese view. Chinese children are not expected to be autonomous of their families to the same extent, with dependence on parents up to the time they are married. The protection and care of their children is the duty of parents. Chinese parents would look upon the failure to fulfill this duty as violating the most basic of parental responsibility. Dependence is the inevitable corollary and not something to shed as soon as possible but the expression of strong family bonds of affection.16. What’s the primary relationship in an Australian family and in a Chinese family?17. What role do children play in an Australian family?18. Why don’t Chinese children do household chores at home?19. What are Australian children expected to do during their school years?20. What’s the main idea of the passage?Part 2: Questions 21--25 are based on this part. (10points)Read Passage 2 and then decide whether Statements 21- 25 are True or False according to the information given in the passage. Write ‘T’ for true and ‘F’ for false on the Answer Sheet.Passage 2The English CharacterNo Englishman believes in working from book learning. He suspects all theories, philosophical or other. He suspects everything new, and dislikes it, unless he can be compelled by the force of circumstances to see that this new thing has advantages over the old. Race-experience is what he invariably depends upon, whenever he can, whether in India, in Egypt, or in Australia. His statesmen do not consult historical precedents in order to decide what to do: they first learn the facts as they are; then they depend upon their own common sense, not at all upon their university learning or upon philosophical theories. And in the case of the English nation, it must be acknowledged that this instinctive method has been eminently successful. The last people from whom praise can be expected, even for what is worthy of all praise, are the English. A new friendship, a new ideal, a reform, a noble action, a wonderful poem, an exquisite painting -- any of these things will be admired and praised by every other people in Europe long before you can get Englishmen to praise. The Englishman all this time is studying, considering, trying to find fault. Why should he try to find fault? So that he will not make any mistakes at a later day. He has inherited the terrible caution of his ancestors in regard to mistakes. It must be granted that his caution has saved him from a number of very serious mistakes that other nations have made. It must also be acknowledged that he exercises a fair amount of moderation in the opposite direction -- his modern Englishman; he has learned caution of another kind, which his ancestors taught him. ‘Power should be used with moderation; for whoever finds himself among valiant men will discover that no man is peerless.’ And this is a very important thing for the strong man to know -- that however strong, he cannot be the strongest; his match will be found when occasion demands it. Not only Scandinavian but English rulers have often discovered this fact to their cost.The judgment of the Englishman by all other. European peoples is that heis most suspicious, the most reserved, the most unreceptive, the most unfriendly, the coldest- hearted, and the most domineering of all western peoples. Ask a Frenchman, an Italian, a German, a Spaniard, even an American, what he thinks about Englishmen; and every one of them will tell you the very same thing. This is precisely what the character of men would become who had lived for thousands of years in the conditions of northern society. But you would find upon the other hand that nearly all nations would speak highlyof certain other English qualities- energy, courage, honor, justice (between themselves). They would say that although no man is so difficult to make friends with, the friendship of an Englishman once gained is more strong and true than any other. And as the battle of life continues, and must continue for thousands of years to come, it must be acknowledged that the English character is especially well fitted for the struggle. Its reserves, its cautions, its doubts, its suspicions, its brutality -- these have been forit in the past, and are still in the present, the best social amour and panoplyof war. It is not a lovable nor an amiable character; it is not even kindly. The Englishman of the best type is much more inclined to be just than he isto be kind, for kindness is an emotional impulse, and the Englishman is on his guard against every kind of emotional impulse. But with all this, the character is a grand one, and its success has been the best proof of its value.21. The Englishmen are willing to see the advantages of new things.22. The Englishmen would rather depend on their race experience than university learning or philosophical theories.23. It is less likely to get praise from an American than from an Englishman.24. Being quite cautious, the Englishman has avoided making a lot of mistakes that other nations have made.25. Emotional impulse is one of the English characters.Section Ⅲ: Communication Analysis [30 points]Instructions; The following are three different cases of cross-cultural communication. In each of the cases there is something to be improved upon. Write an analysis on what is to be desired for more successful communicationor cultural understanding in each case by answering Questions 26-28 respectively. Your analysis of each case should be about 100 -- 150 words. Write your answers on the Answer Sheet.Note:! Your writing ability will also be assessed in this section of the test. Case 1 (7 points)Li Gang is a new Chinese student in an American university. He is very glad that one of his classmates, Peter, invites him to see a film one day. Li Gang goes to the cinema on time. When he gets there, Peter is waiting for him. Peter says, ‘I have bought mine. You go quickly to buy your ticket.’ Li Gang gets surprised.Question 26. Why does Li Gang get Surprised?Case 2 :(10 points)Mrs. Chen has just moved to America. Her husband is a guest professor there. She finds that a car is very necessary in America, so she decides to buy one. After she has chosen a suitable car, she takes out the cash to pay. The salesman is very glad and surprised, ‘Great. You pay in cash. ‘Mrs. Chen gets confused.Question 27: Why does Mrs. Chen get confused?Case 3 (13 points)Sarah and Daniel are a young American couple who are teaching English at Zhejiang University. They are leaning Chinese and enjoy their new lives. They have been eager to get to know Chinese people better so were pleased when Chen’ Li, their new Chinese colleague invited them to her h ome for? dinner at one weekend:When Sarah and Dahiel arrived, Chen Li introduced them to her hus- band Wang Bing, asked them to sit down at a table containing 8 plates of various cold dishes served them tea and then disappeared with her husband into the kitchen. Sarah offered to help in the kitchen but Chen Li said she didn’t need any help.A half-hour later she came back and sat down and the three began to eat. Wang Bing came in from time to time to put several hot dishes on the table. Most of the food was wonderful and there was much more than Sarah and Daniel could eat. They wanted Wang Bing to sit down so that they could talk to him. Finally he did sit down and ate a bit, but quickly he turned on the TV to show them high tech features. Soon it was time for Sarah and Daniel to go home.Sarah and Daniel felt slightly depressed by this experience, but returned the invitation one month later. They decided to make a nice American meal and felt lucky to find olives, tomato juice, butter and even some cheese in the hotel shop. They put these out as appetizers. For the main course they prepared spaghetti and a salad with dressing made from oil, vinegar, and some spices they found in the market.When Chen Li and Wang Bing arrived they were impressed by the apartment and the decorations, and asked about the price of the furniture, paintings, the carpet and other things. Sarah politely refused to answer their questions. They took small tastes of the appetizers and ate only a little spaghetti and didn’t finish the salad on their plates. Sarah urged them to eat more but they refused. Sarah and Daniel talked about their families and asked the Chinese couple about theirs.

Guests would not ask any private questions, such as the price of the furniture, etc. These Western ‘conventions help explain the way Sarah a nd Daniel treated Chen Li and Wang Bing. Chen Li and Wang Bing followed the Chinese conversation habit, that’ S Why they asked about the prices, and often Chinese guests want to show their cultivation and manners by eating limited amount of food, and this may explain Why Chen Li and Wang Bing ate only a little food.3) It is advisable for both couples to learn the other culture through experience, chatting, observing and reading. On suitable occasions, e.g. at parties, friendly and interesting conversations about their respective cul tures, Such as ways of entertaining guests, normal conversation’ ‘topics and taboos etc, can be an effective way of understanding each other‘ Through such interactions; their friendship will surely be enhanced。

以日K线为例,每天股票价格从开盘到收盘走完一天,对应一根蜡烛小图,要表示四个价格:开盘价格Open(早上刚刚开始开盘买卖成交的第1笔价格)、收盘价格Close(下午收盘时最后一笔成交的价格)、中间的最高价High和最低价Low。

如果Close<<<Open,表示为“BW-Solid”(即“实心蓝白蜡烛”);如果Close>>>Open,表示为“R-Hollow”(即“空心红蜡烛”);如果Open等于Close,则为“R-Cross”(即“十字红蜡烛”)。

如果Low比Open和Close低,称为“Lower Shadow”(即“有下影线”),如果High比Open和Close高,称为“Upper Shadow”(即“有上影线”)。

请编程序,根据给定的四个价格组合,判断当日的蜡烛是一根什么样的蜡烛。

输入格式:输入在一行中给出4个正实数,分别对应Open、High、Low、Close,其间以空格分隔。
