a 6 6e+154 0 1 1
b 10 10e+154 1 -1e+5 -4
c -4 -4e+154 1 1 3.999999
-1e+155 -7e+155 1e+155 答案：第二种方法更准确，因为第一种方法是一个累加的过程。 matlab 的 x = a : h : b 和 x = a + (0 : n) ∗ h 是第二种方法实现的。 代码： format long e a = 0; b = 8; n = 9; h = (b-a)/n; x(1) = a; y(1) = a; for j = 1:n, x(j+1) = x(j) + h; y(j+1) = y(1) + j*h; end [x',y',(a:h:b)',a+(0:n)’*h] 第二章 插值法 1. 当 x = 1, −1, 2 时，f (x) = 0, −3, 4，求 f (x) 的二次插值多项式。 （计算两遍，分别用拉格朗日插值和牛顿插值）

一个有趣的心理测试
一个有趣的心理测试：找出一张空白的纸，找支笔，用最快的的时间，画只小猪出来。
你想怎么画就怎么画。
好了，猪画好了吧，看看你画的猪吧，多丑都没关系，不是美术比赛哦，是个性测试，能透露出某些性格特点的：你画在纸的中间还是偏上，还是偏下一点呢，偏上者为乐观积极者，偏下者为消极悲观者，居中则是比较正常的（据说大多数人是居中）；你画的猪是向左的吗，如果是，那么你是比较传统、顾家的，如果是向右，或者正立的，那么是喜欢标新立异者，甚至有人没有画出猪的身体，只有一个猪脑袋，哈哈，那么就是更加有创意、与众不同的啦。
耳朵大吗，那么你是善于倾听者，反之，就是不爱听别人的。
细节画的多吗，比如，鼻孔、小蹄子，眼睛。
细节画的越多的，就是细心、细腻的人，反之，就是粗枝大叶型的。
（有个同事甚至画出了猪猪的双眼皮，哈哈）最后一条，有尾巴么，如果有，并且画的仔细，比较长，或者再打个弯儿的，那么就是说明，感情生活很美妙啊。
你的猪画成什么样的呢？活动介绍方法：在白纸上或者电脑上，画上房子、树和人，三者都要出现在画面上，其他爱怎么画就怎么画，随心所欲地涂鸦吧！这原本是一道心理测试，不要搜百度，不要受暗示。
房：人们成长的场所，投射内心的安全感画楼房：智商较高；房子画得像庙宇：两个极端，要不就是人才，或者就是怪异的行为表达；强调地面：缺乏安全感；瓦片画得很仔细：追求细节和完美；房子侧面画楼梯：想回避和间接性接触；画烟囱：向上的直烟暗示受测者需要出气筒；向上的烟代表受测者内心的压力；一般人画的烟方向会向右，如果向左可能有精神分裂的倾向。
树：象征感情，投射人们对环境的体验单线条的树：受测者内心忧郁，如果除了单线条的树外还画了落叶，受测者很可能在10天之内有自杀倾向；嫩叶：受测者渴望或正在重新开始；树干涂黑或树根呈鹰爪状：受测者潜在的攻击意识较强；柳树：男性受测者较女性化；女性受测者则较追求完美；女性画松树：追求成熟，较男性化。
白桦树：受测者较敏感；画上树疤：受测者曾受过心理创伤，可以根据树疤在树干上的位置判断受创的大致年纪；画果实：受测者童心未泯或有退行行为；高山上一棵树：受测者可能有性行为问题或恋母情结。

新编大学英语 文化阅读教程1教师用书Unit_5
新编大学英语文化阅读教程1教师用书Unit 5Warm-upStep 1 Talk about the picturesIn the first picture the woman thinks that everyone in China knows how to play kung fu. In the second picture the woman assumes that it’s cold every where in Russia. Stereotypes about cultures still exist. They may be a fallacy and may sound weird. For example, when you meet a person from Africa, you may think his living place must be very hot, but actually some African countries, such as Kenya, have a very nice and comfortable weather, neither cold nor hot.Step 2 Sharing your ideasThe key to removing cultural misunderstandings is to let others understand the ideas and history that lie underneath Chinese cultural. On the one hand, we should take the initiative in explaining to foreign friends the reasons for certain thoughts and practices in Chinese cultures.On the other hand, we should also know more about our country’s history and philosophy, and promote our culture in international communication.Reading 1Language focus1.synonymous2.Against all odds3.dominant4.offensive5.icons6.conservative7.piling up8.blend9.rituals10.delightedGlobal understanding1)Spring Festival2)watered down3)purists4)hotpot5)cultural customs6)interpersonal relationships7)adapted to8)dominantDetailed understanding1.Both the Spring Festival and Valentine’s Day are associated with the beginning of spring. With the Spring Festival, its connection to spring is self-explanatory, while for Valentine’s Day, its date marks the end of winter and the start of the season for love. And both festivals emphasize the importance of family love in all forms, whether it is between lovers, or between children and parents.2.The author rejects this cultural view, but he equally rejects the blending of festivals in a hotpot where all the traditions mix into one.3.Culture improves interpersonal relationships via cultural customs. Socially-acceptable performances such as smiles, handshakes or bows can help people communicate meaning more clearly. Once individuals pick up these habits, theycan use them to convey ideas without causing misunderstandings.4.The reason why Confucians dismissed Buddhism is that Buddhism as a religious culture advocates avoiding family responsibilities.5.The author is glad to celebrate both. He thinks Saint Valentine would be joyful to see family members embrace each other on the Spring Festival, and Confucius would definitely be content to see people express their love to one another on Valentine’s Day at the celebration of love at the heart of the human experience.Cultural thinkingCulture exchange should involve absorbing other cultures and at the same time, promoting our own. One way to preserve our tradition is through introducing our culture to the world. Sharing our culture doesn’t mean giving foreign friends tangible items that remind them of our country. Our cultural traditions can be shared through storytelling, music, song, dance, or art. To do so, we should first learn more about our own history and traditions, and then present our history in creative ways to the foreigners in cross-cultural communication. For example, as we meet new people in a foreign country and start to establish friendships, we may take part in their celebrations or significant events. We can also explain to our new friends how we celebrate our milestones like new births, birthdays, and marriages in our home country. Such cultural exchanges create opportunities for meaningful dialogues, and we can preserve our traditions by introducing them to people in other countries.Reading 2Language focus1.settle down2.confrontation3.put up with4.shoved5.virtually6.confusion7.yelled8.stern9.made off10.anxiouslyGlobal understanding1)left 20 yuan2)shoved3)careful4)plates and bowls5)slipped6)back pocket7)broken man8)delivery boy Detailed understanding1. B2. A3. B4. D5. CCultural thinking1)The author sticks to his own habits in another culture. I can understand himbut I don’t support this behavior.2)Answer 1: I don’t think his girlfriend is right to tell him he must tip a deliveryboy. To tip a delivery boy is not that popular in China, and the author has the right to choose whether to tip and how much to tip.Answer 2: Yes, his girlfriend is right. Compared with a waitress who serves guests dishes in a restaurant, a delivery boy makes more efforts to provide customers with convenience. Therefore, it’s better to tip a delivery boy.3)Answer 1: If I travel to a foreign country, I would follow the local culturaltraditions. As one of the Chinese idioms goes, “入乡随俗;”or as the well-known proverb says, “When in Rome, do as the Romans do.” It is advisable to follow the local cultural traditions when one travels to a foreign country.Answer 2: If I travel to a foreign country, I would stick to my own habits. This can be considered as a way to promote our country’s culture, which may finally advance cultural exchange and integration.Integrated thinking1)Cultural exchange and cultural integration are inevitable in this increasinglyglobalized world. They make us more conscious of our own culture and appreciate it even more. Furthermore, they help us discover a lot of differences between other cultures and ours, so that we can learn some values from other cultures. Also, embracing other cultures opens up opportunities for us to expand our abilities. Being in a place out of the comfort zone, we can develop the capacity to adapt to a foreign environment and learn to communicate and express ourselves in a proper manner.Cultural exchange and cultural integration are wonderful in many ways, but don’t come without their costs. As cultures across the globe are integrated with each other, many countries feel that their own culture is being lost in what could be described as the growing “world culture.” As new views and ideas compete for our attention, certain cultural perspectives are left discarded and forgotten. It is sometimes argued that this is robbing certain locals of their heritage.2) Answer 1: An example showing positive impact on local culture:When the ideas of Renaissance spread from Italy to other parts of Europe, they stimulated the development of science and culture in those countries.Answer 2: An example showing negative impact on local culture:Under the influence of globalization, many minority languages have gradually disappeared and been replaced by the lingua franca.Culture mosaic1 Chopsticks for my steak, please1)I think haipai xican is a very unique and interesting cultural phenomenon. It’sa result of integration of Eastern culture and Western culture in aninternational city — Shanghai.2)Answer 1: I prefer to eat Western cuisine with chopsticks. In China, I keep anopen mind on eating Western cuisine with chopsticks as long as the dishes themselves are delicious. I believe most Chinese people can understand this because chopsticks are easier for us to use.Answer 2: I would like to eat Western cuisine without chopsticks. Especially when I travel to the West, I prefer to adapt myself to the local culture, such aseating a steak with a knife and fork in a Western country. Such manners can help me show respect to the local culture.2 Chinese viewers criticize Disney’s new Mulan for being inauthenticI agree with the negative comments, since their criticism is from an expert point of view. However, I prefer to adopt a tolerant attitude toward such Chinese-themed movies made by foreigners. Although there are some inaccurate details in Mulan, this film in general has set a good example of spreading the traditional Chinese culture and introducing the image of a brave Chinese woman to foreign countries. Besides, a tolerant attitude would encourage more and more producers of movies and TV series to tell famous traditional Chinese stories in English or other languages. The more comes out, the more chances for movie critics to correct other cultures’ misunderstandings about Chinese culture.3 Legacies of the Silk RoadCultural exchange in this globalized world has brought about many changes. I will give some examples from the aspects of food and language.Food:Nowadays in China, especially in large cities, we can see many restaurants serving foreign dishes, such as Pad Thai in a Thai restaurant, sushi in a Japanese restaurant, and pizza and pasta in an Italian restaurant. Similarly, in some foreign countries, there are many Chinese restaurants, either in Chinatowns or in other places across the country.Language:More and more Chinese people can communicate in English and some other languages, while more foreign people begin to learn Chinese. An increasingnumber of people are bilingual or trilingual, some of whom even mix their mother tongue with foreign language when they speak.。
