A)One evening a few years ago I found myself in an anxiety.Nothing was really wrong my family and I were healthy, my career was busy and successful--I was just feeling vaguely down and in need of a friend who could raise my spirits, someone who would meet me for coffee and let merant until the clouds lifted.I dialed my best friend, who now lives across the country in California, and got her voicemail.That's when it started to dawn on me--lonesomeness was at the root of my dreariness.My social life had dwindled to almost nothing, but somehow until that moment I'd been too busy to notice.Now it hit me hard.My old friends, buddies since college or even childhood, know everything about me;when they left, they had taken my context with them.B)Research has shown the long-range negative consequences of social isolation on one's health.But my concerns were more short-term.I needed to feel understood right then in the way that only a girlfriend can understand you.I knew it would be wrong to expect my husband to replace my friends: He couldn't, and even if he could, to whom would I then complain about my husband? So I resolved to acquire new friends--women like me who had kids and enjoyed rolling their eyes at the worlda little bit just as I did.Since I'd be making friends with more intention than I'd ever given the process, I realized I could be selective, that I could in effect design my own social life.The down side, of course, was that I felt pretty frightened.C)After all, it's a whole lot harder to make friends in midlife that it is when yon're younger--a fact woman I've spoken with point out again and again.As Leslie Danzig, 41, a Chicago theater director and mother, sees it, when you're in your teens and 20s, you're more or less friends with everyone unless there's a reason not to be.Your college roommate becomes your best pal at least partly due to proximity.Now there needs to be a reason to be friends.“There are many people I'm comfort-able around, but I wouldn't go so far as to call them friends.Comfort isn't enough to sustain a real friendship,” Danzig says.D)At first, finding new companions felt awkward.At 40 I couldn't run up to people the way my4-year-old daughters do in the playground and ask, “Will you be my friend? Every time you start anew relationship, you're vulnerable again,” agrees Kathleen Hall, D Min, founder and CEO of the Stress Institute, in Atlanta.“You're asking, 'Would you like to come into my life?' It makes us self-conscious.”

E)Fortunately, my discomfort soon passed.I realized that as a mature friend seeker my vulnerability risk was actually pretty low.If someone didn't take me up on my offer, so what: I wasn't in junior high, when I might have been rejected for having the wrong clothes or hair.At my age I have amassed enough self-esteem to realize that I have plenty to offer.F)We're all so busy, in fact, that mutual interests--say, in a project, class, or cause that we already make time for--become the perfect catalysts for bringing us in contact with candidates for camaraderie.Michelle Mertes, 35, a teacher and mother of two in Wausau, Wisconsin, says anew friend she made at church came as a pleasant surprise.“In high school I chose friends based on their popular-ity and how being part of their circle might reflect on me.Now's it's our shared values and activities that count.” Mertes says her pal, with whom she organized the church's youth programs, is nothing like her but their drive and organizational skills make them ideal friends.G)Happily, as awkward as making new friends can be, self-esteem issues do not factor in--or if they do, you can easily put them into perspective.Danzig tells of the mother of a child in her son's pre-school, a tall, beautiful woman who is married to a big-deal rock musician.“I said to my husband, she's too cool for me,'” she jokes.“I get intimidated by people.But once I got to know her, she turned out to be pretty laid-back and friendly.” In the end there was no chemistry between them, so they didn't become good pals.“I realized that we weren't each other's type, but it wasn't about hierarchy.” What midlife friendship is about, it seems, is reflecting the person you've become(or are still becoming)back at yourself, thus reinforcing the progress you've made in your life.H)Harlene Katzman, 41, a lawyer in New York City, notes that her oldest friends knew her back when she was less sure of herself.As much as she loves them, she believes they sometimes respond to is-sues in light of who she once was.An old chum has the goods on you.With recently made friends, you can turn over a new leaf.I)A new friend, chosen right, can also help you point your boat in the direction you want to go.Hanna Dershowitz, 39, an attorney and mother in Los Angeles, found that a new acquaintance from workwas exactly what she needed in a friend.In addition to liking and respecting Julia, Dershowitz had a feeling that the fit and athletic younger woman would help her to get in shape.J)While you're busy making new friends, remember that you still need to nurture your old ones.We asked Marla Paul, author of The Friendship Crisis: Finding, Making, and Keeping Friends When You “re Not a Kid Anymore, for the best ways to maintain these important relationships.Keep in touch.Your friends should be a priority;schedule regular lunch dates or coffee catch-up sessions, no matter how busy you are.Know her business.Keep track of important events in a friend's life and show your support.Call or e-mail to let her know you're thinking of her.Speak your mind.Tell a friend(politely)if something she did really upset you.If you can't be totally honest, then you need to reexamine the relationship.Accept her flaws.No one is perfect, so work around her quirks--she's chronically late, or she's a bit negative--to cut down on frustration and fights.Boost her ego.Heartfelt compliments make everyone feel great, so tell her how much you love her new sweater or what a great job she did on a work project.46.Leslie Danzig thought making friends at one's middle age needed some reasons.47.A well-chosen new friend can help you go in the direction that you like.48.A few years ago the author felt lonely and depressed when she phoned her best friend in another city who was much wanted then but unavailable.49.According to Kathleen Hall, one might feel sensitive in the first curse of making new friends.50.Midlife friendship can help you realize your direction of life and reinforce the progress you've made in your life.51.In Mafia Paul's book, to be a better friend, you should keep track with your fiiends, care for your friend's job, express yourself, accept her flaws and compliment your friend for her/his good dressing and job.52.For the author, a girl friend might be the right person to under ”stand her and erase her negative feeling.53.According to Michelle Metes, midlife friendship is based on the shared values and activities

54.As a mature friend seeker, the author finds herself with enough confidence to offer and take rejection with grace.55.With newly made friends, you can have a chance to take on a new look in your life.Section B

交友之道

A)数年前的一天晚上，我发现自己陷入了焦虑中。事实上，一切事情祁如常，我和家人都很健康；我工作忙碌，事业有成。我只是隐隐约约感到情绪很低落，急需一个朋友能给我打打气，跟我喝杯咖啡，听我尽情发泄直到烟消云散。我最好的朋友住在加州—这个国家的另一端。我拨通了她的电话，却听到要求留言的录音。阴影从此开始笼罩着我，孤独是我沮丧的根源。我的社交生活已经减少到几乎没有，但不知何故，直到那一该，我才注意到这一点。现在，这种感觉却狠雏地撞击着我。戈的那些老朋友们，从大学甚至孩提时代就已深交的密友，对我了如指掌，但他们一离开，也把我生活的环境一并带走了。

B)研究表明，缺少社交生活对人的健康会产生长期的消极后果。还好，我妁焦虑期持续时间相当短暂。l521在那时我需要被理解，是只有女性朋友才能理解的那种方式。我知道期望我的丈夫取代喷油的想法是 错误的：他不能，即使他能，我又和谁倾诉我对丈夫的抱怨呢?于是，我下定决心要结交新朋友，目标是像我一样——有孩子而且关注这个世界的妇女。因为我这样交友的目的性更明确，我逐渐意识到，我是可以进行选择的，我实际上是可以设计我的社交生活的。当然它的消极一面就是我感到非常害怕。

C)毕竟，在中年时期交友要比年轻时困难得多一——这是个客观存在的显示，与我聊过的女性曾不止一次地指出这一点。41岁的Leslie Danzi9是芝加哥的一位戏剧导演，也是一位母亲，1461她的看法是，在十几岁、二十几岁的时候，除了有特殊理由不能成为朋友的情况，人差不多可以跟所有人成为朋友。你的大学室友，至少余因为走得比较近而成为你最好的朋友。一现在，我们则需要理由才能成为朋友。Danzi9说，“有很多人，我跟他们在一起的时候很舒服，但我不会因此称他们为朋友。舒适度还不足以维持真正的友谊。”

D)一开始的时候，寻找新的伙伴的确让入有点尴尬。四十岁了，我无法像我四岁的女儿那样在操场上碰到人就问：“能跟我做朋友吗?”。【49】 每次建立一群新关系，你就会又变得脆弱了，”，KathleenHall，教牧学博士，亚特兰大压力研究所的创始人兼首席执行官，赞同这一看法。她说：“你是在问：„你愿意参与到我的生活中吗?‟这使我们局促不安。”

E)幸运的是，我的不适感很快就过去了。我意识到，作为一个寻找朋友的成年人，我变得脆弱的风险其实是非常低的。如果有人不愿意接受我的请求，那又如何呢?我不再是个初中生，那时我可能会因为穿不搭调的衣服或者发型不好看而被拒绝。【54】到了我这个年纪。我已经方足够的自信，我以为我有足够吸引对方的东西。

F)事实上，我们都很忙，以至于共同的兴趣，譬如，我们为之忙碌的项目、课程或事业，就成为把我们与建立伙伴关系的候选人联系在一起的理想的催化剂。35岁的MichelleMertes是盛斯康辛州沃索地区一名教师及两个孩子的母亲，她说在教会结交的新朋友对她来说是一份惊喜。【53】 Mertes说，上中学对，我是根据他们的受欢迎程度以及成为她们圈子的一员可能对或卢生的影响来选择朋友的。现在，共同的价值观和参加的劳动则成为我选择朋友的关键因素。二她与一起组织教会的青年项目的好朋友，虽然性格不同，但她们的干劲和组织能力使她们成为彼此的理想好友。

G)令人高兴的是，尽管结交新朋友是一件尴尬的事情，但自尊问题不是结交朋友需要考虑的因素—～否则，如果将自尊问题作为结交朋友的考虑因素，你也能很容易地洞察这一点。Danzig讲述了她儿子所在的幼儿园的一个孩子的母亲的故事。那位女士身材高大，美丽动八，嫁给了一位有名的摇滚音乐家。“我曾跟我的丈夫说，„对我来说她太酷了，”她开玩笑道。“周围的人都告诫我要警惕。但是，当我跟她混熟了，才发现她原来是个非常悠闲而友好的人。”最终，她们之间因为没有“化学反应”，没能成为好朋友。“我意识到，我们不是同一类人，但这跟社会地位没有关系。”【50】现在看来：中年友谊似乎能反应你所属的类型(或正在成为的类型)，从而加强你在生活中取得的进展。

H)41岁的Harlene Katzman是纽约市的一名律师，她认为，在她无法确定自已是否变样的时候，最老的朋友知道她原来的样子。她依然非常爱她们，她相信她们有时对问题的反应能够反映出她曾经的样子，拥有老朋友对你而言大有益处。【55】而跟新交的朋友在一起：纭可以翻开新的一页。

I)【47】新朋友，如果选择对了的话，还可以帮助找到航行的方向。39岁的Hanna Dershowitz是洛杉矶的一名律师，也是一位母亲。她发现，她在工作中新结交的一个人，Julia，正是她需要的好友。除了喜欢和尊重Julia，Dershowitz有一种感觉，这个健康且从事运动事业的年轻女性能帮助她保持身材。

J)当你忙着结交新朋友时，请记住，你仍需要与老朋友们培养感情。我们请Maria Paul，《友谊的危机：当你不再是孩童时，如何寻找朋友、结交朋友与保持友情》的作者，告诉我们维持这些重要关系的最佳途径。保持联系。朋友至上。无论你有多忙，都要抽空定期与朋友吃顿饭或者喝杯咖啡闲聊。了解她的事业。知道朋友生活中经历的重要事件，并适时表示你的支持，打电话或者发邮件让她知道你时刻都在想着她。坦诚相待。如果朋友确实做了让你懊恼的事情，一定要(委婉地)告诉她。如果你不能完全坦诚的话，就需要重新审视这段关系。包容她的缺点。人无完人，因此不要纠结于她的怪癖～她经常迟到或者她有一点消极——以减少挫折和斗争。满足她的自尊。真心的赞美使人感觉良好，所以要告诉她，你多喜欢她的新毛衣，她做了多么伟大的工作。

Directions: In this section, you are going to read a passage with ten statements attached to it.Each statement contains information given in one of the paragraphs.Identify the paragraph from which the information is derived.You may choose a paragraph more than once.Each paragraph is marked with a letter.长篇阅读

Preparing for Computer Disasters

A)Summary: When home office computers go down, many small businesses grind to a halt.Fortunately, taking steps to recover from disasters and minimize their effects is quite straightforward.B)Fires, power surges, and floods, they're all facts of life.We read about them in the morning paper and see them on the evening news.We sympathize with the victims and commiserate over their bad luck.We also shake our heads at the digital consequences—melted computers, system failures, destroyed data.Yet, somehow, many of us continue to live by that old mantra of denial: “It won't happen to me.” Well, the truth is, at some point you'll probably have to deal with at least one disaster.That's just how it goes, and in most aspects of our lives we do something about it.We buy insurance.We stow away provisions.We even make disaster plans and run drills.But for some reason, computer disaster recovery is a blind spot for many of us.It shouldn't be.Home computers contain some of our most important information, both business and personal, and making certain our data survives a disaster should be a priority.Moreover, even the smallest disaster can be a serious disruption.Personal computers have become an integral part of the smooth-running household.We use them to communicate, shop, and do homework, and they're even more vital to home office users.When home office computers go down, many small businesses grind to a halt.Fortunately, taking steps to recover from disasters and minimize their effects is quite straightforward.With a good offsite storage plan and the right tools, you can bounce back quickly and easily from minor computer disasters.And, should a major calamity strike, you can rest assured your data is safe.Offsite Storage: Major Disasters

C)House fires and floods are among the most devastating causes of personal computer destruction.That's why a solid offsite backup and recovery plan is essential.Although many home users faithfully back up their hard drives, many would still lose all their data should their house flood our burn.That's because they keep their backups in relatively close to their computers.Their backup disks might not be in the same room as their computers—tucked away in a closet or even the garage—but they're not nearly far enough away should a serious disaster strike.So, it's important to back up your system to a removable medium and to store it elsewhere.D)There are many ways to approach offsite storage.It starts with choice of backup tools and storage medium.Disaster situations are stressful, and your recovery tools shouldn't add to that stress.They must be dependable and intuitive, making it easy to schedule regular backups and to retrieve files in a pinch.They must also be compatible with your choice of backup medium.Depending on your tools, you can back up to a variety of durable disk types—from CDs to Jaz drives to remote network servers.Although many of these storage media have high capacity, a backup tool with compression capabilities is a big plus, eliminating the inconvenience of multiple disks or large uploads.E)Once you select your tools and a suitable medium, you need to find a remote place to store your backups.The options are endless.However, no matter where you choose, be sure the site is secure, easily accessible, and a good distance away from your home.You may also want to consider using an Internet-based backup service.More and more service providers are offering storage space on their servers, and uploading files to a remote location has become an attractive alternative to conventional offsite storage.Of course, before using one of these services, make certain you completely trust the service provider and its security methods.Whatever you do, schedule backups regularly and store them far away from your home.Come What May: Handling the Garden Variety Computer Crisis F)Not all home computer damage results from physical disaster.Many less menacing problems can also hobble your PC or destroy your information.Systems crash, kids “rearrange” data, adults inadvertently delete files.Although these events might not seem calamitous, they can have serious implications.So, once again, it's important to be prepared.As with physical disasters, regular backups are essential.However, some of these smaller issues require a response that's more nuanced than wholesale backup and restoration.To deal with less-than-total disaster, your tool set must be both powerful and agile.For example, when a small number of files are compromised, you may want to retrieve those files alone.Meanwhile, if just your settings are affected, you'll want a simple way to roll back to your preferred setup.Yet, should your operating system fail, you'll need a way to boot your computer and perform large-scale recovery.Computer crises come in all shapes and sizes, and your backup and recovery tools must be flexible enough to meet each challenge.The Right Tools for the Right Job: Gearing up for Disaster G)When disaster strikes, the quality of your backup tools can make the difference between utter frustration and peace of mind.Symantec understands this and offers a range of top quality backup and recovery solutions.Norton GoBack is the perfect tool for random system crashes, failed installations, and inadvertent deletions.With this powerful and convenient solution, it's simple to retrieve overwritten files or to bring your system back to its pre-crash state.Norton Ghost is a time-tested home office solution.Equipped to handle full-scale backups, it's also handy for cloning hard drives and facilitating system upgrades.A favorite choice for IT professionals, it's the ideal tool for the burgeoning home office.You can buy Norton Ghost and Norton GoBack separately, or get them both when you purchase Norton System Works.H)Life's disasters, large and small, often catch us by surprise.However, with a little planning and the right tools, you can reduce those disasters to bumps in the road.So, don't wait another day.Buy a good set of disaster recovery tools, set up an automatic backup schedule, and perform a dry run every now and again.Then, rest easy.对应题目： 1.You should take steps to recover from computer disasters so as to minimize their effects.2.For some reason, computer disaster recovery is always ignored by many of us.3.You can bounce back quickly and easily minor computer disasters with the help of a good offsite storage plan and the right tools.4.The most devastating causes of personal computer destruction includes house fires and floods.5.It's necessary for us to back up our systems to some transferable medium and to put it somewhere else.6.You should find a distant place to store your backups after selecting your tools and a suitable medium.7.Not only physical disaster can damage your computer.8.The backup and recovery tools must be flexible enough to deal with various computer crises.9.The quality of your backup tools determines whether you are frustrated or have a peaceful mind when disaster strikes.10.You should prepare for your computer disasters now and again.答案参考：

第三篇：英语四级段落翻译练习(一)

段落翻译

一、对龙图腾的崇拜在中国大约已绵延了八千多年。中国龙是古人将鱼、蛇、马、牛等动物与云雾、雷电等自然天象集合而成的一种神物。中国龙的形成与中华民族的多元融合过程同步。在中国人的心目中，龙具有振奋腾飞、开拓变化的寓意和团结凝聚的精神。

二、秧歌舞是中国汉族的一种民间传统舞蹈，通常在北方省份表演。秧歌舞者通常穿上明亮多彩的表演服装，他们的表演动作有力迅速。在农历春节、元宵节等节日期间，人们一旦听到锣鼓声，不管外面天气有多冷，他们都会蜂拥到街上看秧歌舞表演。近年来，中国东北某些城市的老年人自发组织了了秧歌队，队员常年通过跳秧歌舞来保持健康，同事他们也乐在其中。

三、长城是人类创造的世界奇迹之一。如果你到了中国却没去过长城，就想到了巴黎没有去看看菲尔铁塔，或者就像到了埃及没有去看金字塔一样。人们常说：“不到长城非好汉。”实际上，长城最初只是一些断断续续的城墙，直到秦朝统一中国后才将其连城长城。然而，今天我们看到的长城——东起山海关，西至嘉峪关——大部分都是在明代修建的。

四、饺子是深受中国人民喜爱的传统食品。相传为古代医圣张仲景发明。饺子的制作是包括： 1）擀皮、2）备馅、3）包馅水煮三个步骤。其特点是皮薄馅嫩，味道鲜美，形状独特，百食不厌。民间有“好吃不过饺子”的俗语。中国人接亲待客、逢年过节都有包饺子吃的习俗，寓意吉利。对崇尚亲情的中国人来说，“更岁交子”吃饺子，更是欢度除夕、辞旧迎新必不可少的内容。

五、针灸是中医学的重要组成部分。按照中医的经络理论，针灸疗法主要是通过疏通经络、调和气血，来达到阴阳归于平衡，使脏腑趋于调和之目的。其特点是“内病外治”。主要疗法是用针刺入病人身体的一定穴位，或用艾火的温热刺激烧灼病人的穴位，以达到刺激经络。治疗病痛的目的。针灸以其独特的优势，流传至今并传播到了世界，与中餐、功夫、中药一起被海外誉为中国的“新四大国粹”。

六、中国功夫即中国武术，是将技击寓于搏斗和套路运动之中的中国传统体育项目，承载着丰富的中华民族传统文化。其核心思想是儒家的中和养气之说，同时兼容了道家、释家的思想。中国武术源远流长、流派林立、拳种繁多，讲究刚柔并济、内外兼修，蕴含着先哲们对生命和宇宙的参悟。后世所称十八般武艺，主要指：徒手拳艺，如太极拳、形意拳、八卦掌等；器械功夫，如刀枪剑戟、斧钺钩叉等。

七、汉字是从原始人用以记事的简单图画，经过不断演变发展最终成为一种兼具音、形、意韵的独特文字。现存中国古代最早成熟的文字是甲骨文，被认为是现代汉字的初形。此后，汉字又经历了金文、隶书、楷书、草书、行书等不同的阶段。汉字结构“外圆内方“，源于古人”天圆地方“的观念。汉字有五种基本笔画，即：横、竖、撇、捺、折。

八、中国人使用筷子就餐的方式在世界上独树一帜。有史记载用筷的历史已有三千多年。筷子古时称为箸，它看似简单，但却同时具有夹、拨、挑、扒、拌、撮、戳、撕等多种功能。中国民间视筷子为吉祥之物，如婚俗中将筷子隐喻为快生贵子的祝福等。与使用刀叉以及手抓的 方式不同，成双结对的筷子含有“和为贵“的意蕴。西方人赞誉筷子是古老的东方文明。

九、印章就是图章。中国历代官、私所用的印章有印信、朱记、合同、符、契等等不同的称谓，而帝王所用的印章古时称玺、印、宝、章等。据史料记载，印章在战国时代已普遍使用。印章的制作是将篆隶等字体、图像用阴、阳的形式雕刻而成，形状以圆、方为主。印章用朱色

钤盖，除日常应用外，又多用于书画题识，逐渐成为中国特有的艺术形式之一。

十、天干地支是中国历法中用以记录和命名年岁的方法。十天干为：甲、乙、丙、丁、戊、已、庚、辛、壬、癸；十二地支为：子、丑、寅、卯、辰、巳、午、未、申、酉、戊、亥。古人观测朔望月，发现月亮圆缺12次大体上是一年的天数，而两个朔望月约是60天。古人以十天干与十二地支的顺序依次相配，记录不同年份，60年为一个轮回。干支纪年法从古沿用至今。按干支纪年法，2011年便是辛卯年。C

十一、京剧被誉为“东方歌剧”，是地道的中国国粹。它起源于中国多种古老的地方戏剧，特别是南方的“徽班”。到了19世纪末，京剧形成并成为中国最大的戏曲剧种。京剧是综合性表演艺术，集唱（歌唱）、念（念白）、做（表演）、打（武）、舞（舞蹈）为一体，通过程式化的表演手段，叙述故事，刻画人物。角色主要分生（男性）、旦（女性）、净（男性）、丑（男性女性皆有）四大行当。

十二、道教是中国土生土长长的宗教。创始人是春秋末期的哲学家、思想家老子。道教以老子所著的《道德经》为主要经典。道教主张“重人贵生”。崇尚清静无为，修身养性。“道可道，非常道。名可名，非常名。无名天地之始；有名万物之母。故常无，欲以观其妙；常有，欲以观其徼”便是老子的至理名言。

十三、中国成语是汉语中意义完整的表示一般概念的固定词组或短语。“成语”中的“成”既是约定俗成。成语是比词大而语法功能又相当于词的语言单位。绝大多数的中国成语由四个汉字组成，例如：自强不息、青出于蓝、厚积薄发。成语主要从民间谚语、古代文学作品、诗歌、寓言、典故、名言警句等方面提炼而成，是汉语语言中精炼而又富有生命力的一部分。

十四、中国是丝绸的故乡。栽桑、养蚕、缫丝、织绸是中国古代人民的伟大发明。商周时期丝绸的生产技术就已发展到相当高的水平。西汉时张骞通西域，把中原与波斯湾、地中海紧密联系起来，开辟了中外交流贸易的新纪元。从此中国的丝绸以其卓越的品质、精美的花色和丰富的文化内涵闻名于世，成为中国文化的象征。东方文明的使者。

十五、中国园林是把人造的山水、植物、建筑等与自然地貌有机结合的环境艺术，是我国古代建筑艺术的珍宝。其建造原则是“妙极自然，宛自天开”。游赏中国古典园林，能充分领略“假自然之景，创山水真趣”的园林意境。在世界三大园林体系中，中国园林历史悠久、内涵丰富，被誉为世界造园史上的渊源之一。

十六、笔墨纸砚是中国古代文人书房当中必备的宝贝，被称为“文房四宝”。用笔墨书写绘画在中国可追溯到五千年前。秦时已用不同硬度的毛和竹管制笔；汉代以人工制墨替代了天然墨；有了纸张以后，简牍锦帛逐失其用；砚台则随笔墨的使用而发展。“文房四宝”到宋朝以后特指湖笔、徽墨、宣纸、端砚。可以说文房四宝书写了整个中华文明。

十七、中国书法（calligraphy），像中国汉字一样，最初见于殷商时期（Yin or Shang Dynasty）。书法不是像写字那样仅仅是为了达到社会交流的目的，而是一种用来表达作者思想，抱负以及自身感情的艺术。作为中国上乘艺术世界特有的一个构件，书法也是外国友人津津乐道或者掌握的最富挑战性的艺术形式之一。学习中国书法，必须对中国文字的起源有所了解。书法这门艺术包含了很多理论，也需要很多技巧，能够达到书法艺术最高境界的书法家并无几人。十八、十二生肖（animal sign）在中国非常流行。十二属相是一个用来纪年的十二年的循环（cycle）。长期以来，人们与十二生肖之间有着特别的关系。许多艺术形式都取材于十二生肖。属相有其特别的文化内涵，如属鼠的人往往聪明，懂得积累财富。属相还有助于在社交活动中得知别人的年龄。为了避免直接问及一个人的年龄，人们通常问他的属相，这就可以确定他在十二生肖的排位。然而通常问属相只是在朋友和熟人之间弄明白谁的年龄更大。

十九、农历正月十五日的元宵节（Lantern Festival）是中国的传统节日。自汉代（Han Dynasty）起中国人就开始庆祝元宵节了。如今元宵节已经成为一个人们娱乐消遣的节日。节日期间，各地举行各式各样的灯节，街上会挂起形状不同、大小各异的灯笼，引得无数游人驻足。另外还举行猜灯谜、敲年鼓、耍龙灯、赶庙会等其他娱乐活动。元宵节另一个重要组成部分是吃元宵（也称汤圆），很显然它们是因为元宵节而得名的。

二十、师父/师傅是用来指大师或老师。通常用于武术（martial arts）的语境，表示一种教导关系。在中国大陆，师父/师傅是用来对需要知识或技术的各行各业的一种常见的尊称，例如教师、司机、厨师、家庭装饰人员以及某些行业和艺术中的一些长者，而且他们都有丰富的经验，例如绘画与书法（calligraphy）。在现代俚语（slang）中，人们用这个词来加强与其他人的关系，尤其是不太熟悉的人。

二十一、舞龙（dragon dance）是中国文化中一种传统的舞蹈与表演形式。舞龙最多出现于节日庆祝中，这与舞狮相似。在舞龙中，一队人用竿举着龙。传统的龙在表演中的动作象征着它的历史角色，即对力量和威严的表现。龙深深地扎根于中国文化之中，中国人经常认为自己是“龙的传人”并将其作为民族身份的象征。东方和西方都存在着龙的文化。在西方的许多文学作品中都可以找到龙，而且这些龙与中国龙存在着巨大的差异。

二十二、放鞭炮（firecrackers）是春节庆祝时最盛行的习俗之一。在宋朝，人们用火药制作鞭炮，代替以前的爆竹。最初，放鞭炮是为了驱赶邪恶，寻求幸福。现在放鞭炮驱赶邪恶的用意逐渐淡化，更多的是为了增加节日的气氛。由于燃放烟花爆竹会引起火灾和造成人身伤害，所以近来各地方市区都有规定禁止燃放烟花爆竹。尽管有禁止燃放烟花爆竹的规定，但很多市民还是会到乡村、郊区放烟花来庆祝新年。

一、Chinese Dragon

Dragon totem worship in China has been around for the last 8,000 years.The ancients in China considered the dragon(or loong)a fetish that combines animals including the fish, snake, horse and ox with cloud, thunder, lightning and other natural celestial phenomena.The Chinese dragon was formed in accordance with the multicultural fusion process of the Chinese nation.To the Chinese, the dragon signifies innovation and cohesion.二、Yangko Yangko is one of tradition folk dance of Han in China.It is usually performed in northern provinces.The dancers usually wear colorful and light costumes, and the performance is powerful and rapid.During some festivals such as Spring Festival, Lantein Festival, if people hear the sound of drum and gong, no matter how cold the weather is , they will come to street and appreciate the Yangko.Recent years, the old people in city of east-northern of China organized the team of Yangko by themselves, the teamers keep their health by dancing Yangko the whole year.三、The Great Wall

The Great Wall is one of the wonders of the world that created by human beings!If you come to China without climbing the Great Wall, it's just like going Paris without visiting the Eiffel Tower;or going to Egypt without visiting the Pyramids!Men often say, “He who doest not reach the Great Wall is not a true man.”In fact, it began as independent walls for different states when it was first built, and did not become the “Great Wall” until the Qin Dynasty.However, the wall we see today, starting from Shanhaiguan Pass in the east to Jiayunguan Pass in the west, was mostly built during the Ming Dynasty.四、Dumplings

Dumplings are one of the Chinese people’s favorite traditional dishes.According to an ancient Chinese legend, dumplings were first made by the medical saint---Zhang Zhongjing.There are three steps involved in making dumplings: 1)make dumpling wrappers out of dumpling flour;2)prepare the dumpling stuffing;3)make dumplings and boil them.With thin and elastic dough skin, fresh and tender stuffing, delicious taste, and unique shapes, dumplings are worth eating hundreds of times.There’s an old saying that claims, “Nothing could be more delicious than dumplings”.During the Spring Festival and other holidays, or when treating relatives and friends, Chinese people like to follow the auspicious custom of eating dumplings.To Chinese people who show high reverence for family love, having dumplings at the moment the old year is replaced by the new is an essential part of bidding farewell to the old and ushering in the new year.五、Acupuncture

Acupuncture is an important part of traditional Chinese medicine(TCM).In accordance with the “main and collateral channels” theory in TCM, the purpose of acupuncture is to dredge the channel and regulate qi and blood, so as to keep the body’s yin and yang balanced and achieve reconciliation between the internal organs.It features in traditional Chinese medicine that “internal diseases are to be treated with external therapy”.The main therapy of acupuncture involves using needles to pierce certain acupoints of the patient’s body, or adopting moxibustion to stimulate the patient’s acupoints so as to stimulate the channels and relieve pain.With its unique advantages, acupuncture has been handed down generation after generation and has now spread all over the world.Nowadays, acupuncture, along with Chinese food, kung fu(otherwise known as Chinese martial arts), and traditional Chinese medicine, has been internationally hailed as one of the “four new national treasures.”

六、Chinese Kung Fu

Chinese kung fu, or Chinese martial arts, carries traditional Chinese culture in abundance.It is a traditional Chinese sport which applies the art of attack and defence in combat and the motions engaged with a series of skill and tricks.The core idea of Chinese king fu is derived from the Confucian theory of both “the mean and harmony” and “cultivating qi”(otherwise known as nourishing one’s spirit).Meanwhile, it also includes thoughts of Taoism and Buddhism.Chinese kung fu has a long history, with multi-various sects and many different boxing styles, and emphasizes coupling hardness with softness and internal and external training.It contains the ancient great thinkers’ pondering of life and the universe.The skills in wielding the 18 kinds of weapons named by the later generations mainly involve the skills of bare-handed boxing, such as shadow boxing(Taijiquan), form and will boxing(Xingyiquan), eight trigram palm(Baguazhang), and the skills of kung fu weaponry, such as the skill of using swords, spears, two-edged swords and halberds, axes, tomahawks, kooks, prongs and so on.七、Chinese Characters

Chinese characters were initially meant to be simple pictures used to help people remember things.After a long period of development, it finally became a unique character system that embodies phonetic sound, image, idea, and rhyme at the same time.The writing system, which was extremely advanced in ancient times, began with inscriptions on bones and tortoise shells, and these are regarded as the original forms of Chinese characters.Afterwards, Chinese characters went through numerous calligraphic styles: bronze inscriptions, official script, regular script, cursive script, running script, etc.Chinese characters are usually round outside and square inside, which is rooted in ancient Chinese beliefs of an orbicular sky and a rectangular Earth.The five basic strokes of Chinese characters are “---“(the horizontal stroke)“│”(the vertical stroke), “／”(the left-falling stroke), “＼”(the right-falling stroke), and “乙”(the turning stroke).八、Chinese Chopsticks

The Chinese way of eating with chopsticks is unique in the world.The recorded history of chopsticks started more than three thousand years ago.Chopsticks were named zhu in ancient Chinese.They look deceptively simple to use, but possess multi-various functions, such as clamping, turning over, lifting up, raking, stirring, scooping, poking, tearing, and so on.Chopsticks were taken as an auspicious mascot by ordinary people in ancient China.For example, the partial tone of chopsticks is often used by people as a metaphor at weddings to indicate a blessing or benediction for the couple to have a baby soon.Unlike using a knife and fork or one’s own hands, a pair of chopsticks also implies the meaning of “Harmony is what matters”.Chopsticks are highly praised by Westerners as a hallmark of ancient oriental civilization.九、Chinese Seal

A seal can also be defined as a stamp.Both the Chinese official and private seal of various dynasties have different titles, such as stamp, zhu note, contract, fu, lease and others.The seals used by the emperors of ancient China were called xi, yin, bao, etc.According to historical records, seals were widely used during the Warring States Period(475BC-221BC).The making of a seal is to engrave fonts, such as seal characters and official script and so on;or images in the form of intaglio and embossment into the seal, basically shaped as round or square.Covered with a vermilion overlay, the Chinese seal is not only used in daily life, but it is also used to represent signatures on paintings and calligraphies.It is gradually becoming one of China’s unique artworks.十、Chinese Era

The Chinese era is the symbol that the Chinese calendar uses for recording and naming years.The ten Heavenly Stems are: jia, yi, bing, ding, wu, ji, geng, xin, ren, gui.The twelve Earthly Branches are: zi.chou, yin, mou, chen, si, wu, wei, shen, you, xu, hai.After observing the lunar month, the ancients found that the moon always wazes and wanes roughly 12 times a year, and two lunar months account for about 60 days, so the order of the ten Heavenly Stems and the order of the twelve Earthly Branches are properly matched in turn.In terms of recording date, 60 years is considered to be a full time cycle.The Chinese era chronology was first invented in ancient times and is still in use now.according to the chronology of the “ten Heavenly Stems,” 2011 is the year of “the seventh of the ten Heavenly Stems” and “ the fifth of the twelve Earthly Branches”.十一、Beijing Opera

Praised as “Oriental Opera”, Beijing Opera is a genuine national quintessence of China.It originated from many kinds of ancient local operas, especially huiban in southern China.At the end of the 19th Century, Beijing Opera evolved and took shape, becoming the greatest kind of opera in China.Beijing Opera is a blend of performing arts---song, speech, performance, acrobatix fighting and dance.Beijing Opera portrays and narrates the plot and characters through stylized acting.The main types of roles in Beijing Opera are sheng(male), dan(young female), jing(painted face, male), and chou(clown, male or female).十二、Chinese Taoism

Taoism first originated in China.The founder of Taoism is Laozi, a philosopher and thinker who lived in the late Spring and Autumn Period(770BC-476BC).Tao Te Ching whose authorship has been attributed to Laozi, is considered to be the main Taoist classic.Taoism advocates the value of a human being’s life, recommends the discarding of all desires and worries from one’s mind, and encourages the cultivation of moral character and the nourishment of human nature.The following is an example of Laozi’s golden saying: The way that can be told of is not an unvarying way;The names that can be named are not unvarying names.It was from the nameless that Heaven and Earth sprang;The named is but the mother that rears the ten thousand creatures, each after its kind.Truly, only he that rids himself forever of desire can see the secret essences;He that has never rid himself of desire can see only the outcomes.十三、Chinese Idioms

Chinese idioms refer to comprehensive and integrated fixed phrases and expressions.Idioms are established and accepted by constant usage and common practice.An idiom is a language unit that is larger than a word, but has the same grammatical function as a word.Most Chinese idioms consist of four characters.For example, ziqiangbuxi(make unremitting efforts to improve oneself), qingchuyulan(bluer than indigo), and houjibofa(success comes with time and effort).Idioms are extrated from folk proverbs, ancient works of literature, poems, fables, allusions, and well-known sayings.Idioms are a part of the Chinese language that are concise and have great vitality.十四、Chinese silk

China is the home of silk.Mulberry planting, sericulture, silk reeling and thickening are all great inventions of the ancient Chinese.As early as the Shang and Zhou Dynasties(1600BC-256BC), the Chinese people’s silk-weaving techniques had reached an extremely high level.During the Western Han Dynasty(206BC-25AD), Zhang Qian, an outstanding diplomat, travelled around central Asia and connected China with the Persian Gulf and the Mediterranean, opening up a new era of Sino-foreign trade, exchange and communication.From then on, China’s silk became well known for its extraordinary quality, exquisite design and color, and abundant culture connotations.Hitherto, Chinese silk has been accepted as a symbol of Chinese culture and the emissary of oriental civilization.十五、Chinese Classical Garden

The Chinese classical garden is a precious treasure of our ancient Chinese architecture.It is a kind of environment art, which systematically combines artificial mountains and rivers, plants and buildings with the natural landscape.The construction standard of a Chinese classical garden is “artificial as it is, the garden must look ingenious and natural.” When you go sightseeing in a Chinese classical garden, you should be able to appreciate its artistic concept which “makes use of the natural landscape to create the real fun of mountains and rivers for viewers.” Of the world’s three major garden systems, the Chinese classical garden is hailed as one of the origins of the world’s garden due to its long history and abundant connotations.十六、The Four Treasures of the Study

The writing brush, ink stick, ink stone, and paper were requisite treasures in the study of the scholars of ancient China, and they are often referred to as the “Four Treasures of the Study.” The writing brush and ink stick have been used by the Chinese to write and paint since 5,000 years ago.In the Qin Dynasty(221BC---206BC), people already used feathers of different hardness and bamboo trunks to make brushes.During the Han Dynasty(206BC-220AD), man-made ink was used instead of natural ink.After paper was invented by the Chinese, bamboo slips, wooden tablets, brocade and silk, which originally functioned as writing surfaces, gradually faded out.The ink stone was first developed with the use of writing brushes and ink.After the Song Dynasty(960AD---1279AD), the “Four Treasure of the Study” particularly referred to hubi, the writing brush produced in Huzhou, Zhejiang province;huimo, the ink stick produced in Huizhou, Anhui province;xuan paper, a kind of paper produced in Xuanzhou, Anhui province;and duanyan, the ink stone made in Zhaoqing, Guangdong province(Zhaoqing was earlier called Duanzhou).Indeed, the Four Treasures of the Study” have writtin the whole Chinese civilization, as it is.十七、Chinese Calligraphy Chinese Calligraphy, like character, first appeared during the Yin or Shang Dynasty.Calligraphy, unlike writing for the sole purpose of social communication, is an art used to express the ideas, accomplishments, and feelings of the calligrapher.Calligraphy is a special category in China’s world of fine arts and one of the most challenging Chinese art forms for a foreigner to appreciate or master.Studying Chinese calligraphy one must learn something about the origins of Chinese characters.Calligraphy is an art of form that involves a great deal of theory and requires many skills;consequently there are few calligraphers that have reached the highest realm of calligraphy.十八、Animal Sign The 12 animal signs are very popular in China.The Chinese animal signs are a 12-year cycle used for dating the years.For a long time there has been a special relationship between humans and the 12 animal signs.The 12 animal signs are widely used in many art forms.These animal signs have specific cultural connotations.For example, people under the rat sign are usually smart and willing to accumulate wealth.The animal signs also serve a useful social function for finding out people’s ages.Instead of asking directly how old a person is, people often ask what his or her animal sign is.This would place that person’s age within a cycle of 12 years.More often, asking for animal signs is simply to know who is older among friends and acquaintances.十九、The Lantern Festival The Lantern Festival is a traditional festival celebrated by Chinese on the 15th of the 1st lunar month.Chinese started to celebrate the Lantern Festival since the Han Dynasty.Nowadays the Lantern Festival has become an occasion for people to entertain themselves and have fun.During the Lantern Festival, different lantern appreciation activities are held, lanterns of various shapes and sizes are hung in the streets, attracting countless visitors.Other entertainments such as guessing riddles on lanterns, beating drums, playing dragon lanterns and going to fairs are also held.Another important part of the Lantern Festival is eating small dumpling balls, yuanxiao or tangyuan.Obviously, they get the name from the festival itself.
