Ask someone else what they think.20You can ask two or three or four more people if two isn't enough.21If you mislead or lie to people about your opinions,then it's not surprising that you have a hard time trusting that people's compliments are genuine.Be more honest with people around you,and you'll find it much easier to believe what people say about you.A．They will be the tie breaker.B．You can check with someone else instead.C．The causes are complicated but the path to accepting compliments is simpler.D．How honest are you with your friends and family when they ask for your opinion? E．When someone is trying to pay you a compliment,they are speaking subjectively. F．When someone pays you a compliment,they are speaking about something that is observable. G．Similarly,when I call you smart or funny,I'm commenting based on my definition of smart or funny,that's how I see you.Have you considered contributing your skills and expertise virtually towards achieving sustainable human development efforts?Through the Online Volunteering service of the United Nations Volunteers(UNV)programme,you can connect with UN agencies,governments,public institutions and civil society organizations—from any device,anywhere in the world.While extending your network,you can also get first-hand practical experience.Requirements:·To sign up on the Unified Volunteering Platform and apply for Online Volunteer assignments,you must be at least18years of age.·There is no particular background required to become an Online Volunteer.Each Online Volunteer assignment is different and has its own requirements,set by the host organization.·As an Online Volunteer,you can only support organizations remotely in assignments up to20 hours per week for a maximum of12weeks for each assignment.Criteria and service rules:·Online Volunteers are not under contract with the UNV programme or the engaging organization.·Online Volunteers do not receive any kind of financial benefits.·For each Online Volunteering assignment,a maximum of25Online Volunteers can be engaged. Procedures:·Volunteers find assignments of their interest and apply.·Organizations select the volunteers they want to engage.·Volunteers and organizations work together online.·Volunteers and organizations provide feedback on their cooperation.·Organizations issue an electronic certificate of appreciation to their volunteers. 22．Through the UNV programme,one can______.A．travel around the world B．improve their network skillsC．set up civil society organizations D．work on sustainable development23．Which is a requirement for the applicants?A．Being no less than18years.B．Finishing25online assignments.C．Working at least20hours a week.D．Having some practical experience.24．When working in the UNV programme,volunteers will______.A．sign a contract with an organizationB．find tasks of their interest and applyC．get a paper certificate of appreciationD．receive some kind of financial benefitsYou may not get enough physical activity throughout the day,especially since sitting still is required or encouraged in many jobs,at school,and in social situations.But there’s something you should know.Being physically inactive or sedentary(久坐不动的)can increase health risks.25What counts as being physically inactive?While there is no strict definition of what can be considered a sedentary lifestyle, researchers have a few different measures to assess what a sedentary lifestyle is.One measure is the time an individual spends seated or reclining(向后倚靠)during waking hours.26 Some other researchers label people inactive or sedentary if they take fewer than5,000pedometer (计步器)steps per day.27In the short term,being inactive can increase depression or anxiety.It can also affect the way the body processes fats and sugars in the diet and lead to some weight gain if you aren’t burning enough calories.Over the long term,sedentary lifestyles increase the risk of death from cardiovascular(心血管的)disease,diabetes,and cancer.How can you prevent being inactive?Health authorities recommend exercise at a medium level for either30minutes a day for five days a week or a total of2hours and30minutes per week.Walking is an easy activity to add to your day.28A pedometer or fitness band can show you whether you are getting enough steps.Many people aim to take10,000steps per day,which indicates that you have met your daily physical activity goal.29but the value of being more physically active is worth it for its many benefits.A．How harmful is it?B．What’s the drawback of sedentary lifestyle?C．Fixing a sedentary lifestyle takes some conscious effort at first,D．Now let’s learn about whether you might be classified as inactive or sedentary. E．Simply walking more or doing household chores positively impacts health,F．It can work to break up sitting time and add steps hourly throughout the day. G．Spending four to six waking hours sitting or lying down is considered sedentary.TikTok has many clever tips and tricks to make life a little easier.From creative advice to practical skills,there is something for everyone on the video sharing App.Many of these methods have left viewers open-mouthed at their simplicity or scratching their heads as why they hadn’t thought of them first.But to save you some boring scrolling(滚屏),we have made a list of the best TikTok life tips in2021.Ready to be impressed?Chop onionsChopping onions is an emotional experience or,at least,it looks it.The vegetable can make us tear up,and salty liquid flowing down your cheeks is never a stylish look.However,a woman created a makeshift protective gear out of a hooded sweatshirt(连帽运动衫)and a pan cover. Next step,New York Fashion Week.Clean car headlightsIt is vital that your cars headlights stay in good working order so as to keep you safe.If yours are fogged up,just use a lemon and some baking soda.Many netizens have claimed that this method can save them some serious cash.Bathe your dogIf your dog hates having a bath,why not try peanut butter?While this one may seem ridiculous,one TikTok video has shown it is effective.In the clip the pet can be seen licking it off the side of the tub,as the owner cleans his fur.“I don’t even know I am having a bath.All I know is peanut butter,”the caption(字幕)reads.30．What can we infer from the first TikTok life tip?A．Chopping onions can make you upset.B．You can find the protective gear in New York.C．The makeshift protective gear is creative.D．It’s stylish to have tears flowing down your cheeks.31．Which of the following statements is TRUE according to the passage?A．The tips and tricks sound easy but are difficult to apply.B．You can use a lemon and some baking soda to bathe your dog.C．Cleaning car headlights with a lemon and some baking soda is economical.D．The author finds bathing a dog with the help of peanut butter ridiculous. 32．What’s the author’s purpose in writing this passage?A．To analyze the reasons why people like TikTok.B．To share some clever tips and tricks found on TikTok.C．To come up with some practical suggestions on TikTok.D．To call on people to share more tips and tricks on TikTok.What motivates you to work or study harder?Is it the thought of success and all the amazing things that you can achieve,or is it the fear of failure and worry about all the things that can go wrong for you?Leaders,managers,and teachers have often used one of these ideas to inspire people to work harder and achieve more.33A recent study looked at the effect of fear-based strategies on British secondary school students.They found that if a test is seen as important,and students are optimistic that they can succeed,then the fear of failure can be used successfully by teachers to motivate these learners. However,if students are not confident,fear-based approaches could cause feelings of anxiety. 34The study also found that if students don’t care about the test,then,unsurprisingly,the fear of failure is not likely to motivate them.35It’s a fact that most new companies will fail.But does this motivate or prevent business people?Again,it’s not straightforward.The personal consequences of failure can be significant,and so founders may be motivated to work harder to avoid them.A study carried out on British and Canadian businessmen found that fear of failure can improve problem solving,as people are motivated to anticipate and resolve potential issues.36So it will help their business in the long run.37It can drive confident people to do better,but it can also increase our doubtsand turn them into barriers.A．It may motivate them more.B．But is one better than the other?C．Fear-based motivation is complicated.D．Then it can in turn lead them to do worse.E．Businessmen often run the risk of failure.F．They may also be inspired to learn new things.G．Is this idea beneficial for you to succeed?四、语法填空38．Beijing Olympic Park,also(know)as the Olympic Green,is located in Chaoyang District,Beijing,with a total land area of11.59square kilometers.（所给词的适当形式填空）五、书信写作39．假设你是红星中学高三学生李华，你和你校交换生Jim准备联合参加学校组织的校园文创设计大赛(Campus Cultural and Creative Design Competition),请给Jim发邮件，内容包括：1.分享你的创意;2.询问Jim的建议。

14EDUCATOR特别报道物理学家李淼：科普重在有趣有故事文｜本刊记者 吴爽人物简介：李淼，1962年出生，2013年就职中山大学，创立中山大学天文与空间科学研究院并任院长。

2019年11月就职南方科技大学物理系。

1982年毕业于北京大学天体物理专业；1984年在中国科技大学获理学硕士学位，1988年在该校获博士学位；1989年赴丹麦哥本哈根大学玻尔研究所学习，1990年获理学博士学位。

著有《超弦史话》《〈三体〉中的物理学》《给孩子讲量子力学》等。

他把量子力学、宇宙学和相对论等物理学理论以生动活泼的语言讲给孩子们听，多本科普著作成为畅销书；他在微博上拥有上百万粉丝，被孩子们亲切地称呼为“淼叔”“三水叔叔”；他潜心科研30多年，发表SCI论文160篇，引用总数达6000余次——他就是理论物理学家、科普作家李淼。

几年前，他获得中国科协颁发的“中国十大科学传播人”奖时，获得这样的评价：“他总能用一种生动有趣的口吻谈物理，他让公众看到了物理学家感性、多情的一面。

”科普是一种“服务”十多年前，他就开始了科普工作，有人说他“不务正业”，他回怼：“‘业’是自己定义的，把一件事情做成了，获得成就感，这就是正业。

”做科普的这些年，他初期给报纸、期刊写专栏，之后在微博、微信、直播、电台等社交平台答疑解惑，近几年，参加《朗读者》《火星情报局》等电视节目，常常活跃在科学传播的前线。

今年58岁的李淼表示，他50岁以后的人生重点从科研转向科普和教育。

在他看来，现在做科普正合适。

“年轻人先得将一件事情搞懂、吃透，再去将这件事讲给别人。

所以，我觉得30岁前就做科普不太好。

之后，将自己懂的东西讲给别人就是值得做的事。

50岁之后，做研究通常难以取得好成绩，而语言能力的积累和经验积累却到位了，这时做科普当然最好。

”李淼写的少儿科普系列作品，聚焦于宇宙学。

给孩子们讲量子力学、相对论、时间简史等听起来晦涩高深的物理学知识，孩子们能听懂吗？李淼说：“没有任何学科的任何知识是不能讲给任何人听的，科普其实是一种服务。

破解2012预言—著名物理学家李淼李淼，男， 1982 年毕业于北京大学天体物理专业。

1984 年在中国科技大学获理学硕士学位 ,1988 年在该校获博士学位。

1989 年赴丹麦哥本哈根大学波尔研究所学习， 1990 年获哲学博士学位。

1990 年起先后在美 Santa Barbara 加州大学、布朗大学任研究助理、研究助理教授， 1996 年在芝加哥大学费米研究所任高级研究助理。

1999 年回国，任中国科学院理论物理研究所研究员、博士生导师，曾任台湾大学客座教授、中国科学技术大学客座教授。

李淼教授是国家基金委杰出青年基金获得者、中国科学院“ 百人计划” 入选者、新世纪百千万人工程入选者。

研究量子场论、超弦理论以及宇宙学。

超弦理论中的研究有一定的国际影响，特别是两维刘维尔理论、 D 膜以及黑洞的量子物理等方面。

最近致力于研究超弦中的黑洞物理、超弦宇宙学以及暗能量。

玛雅人的神秘预言，2012 年。

太阳风暴何时到来，南北两极为何倒转，小行星何时降临，宇宙何时走到终点，国内顶级物理学家、中国科学院理论物理研究所李淼接受猫扑专访，为你破解“ 玛雅预言。

人类历史上，从 1999 诺查丹玛斯预言到 2012 玛雅预言。

有关地球和人类毁灭的预言从未间断过。

无论预言自身多么荒谬，但有一点可以相信，预言的根源来自人类对宇宙中那些未知之谜的困惑。

宇宙万物如何诞生和演化？又将如何结束？向全世界的科学家征集答案。

2008 年，美国的邓普顿基金会提出了 15 个关于宇宙的终极问题。

邓普顿基金会在中国设立了两百万美元的专门基金，鼓励中国人研究这些终极问题。

宇宙大约诞生于 137 亿年之前。

但是仅仅在不到 100 年前，根据科学家的推算。

科学家才知道宇宙不是永恒的万物有生就有死，宇宙也不例外，也会死亡。

宇宙中有一场看不见的战争，战争的一方叫做暗物质，另一方叫做暗能量，胜负，决定着宇宙终结的时间，但恐怕那时人类早已从地球上消失了暗能量、暗物质和大撕裂美国和澳大利亚的两个科学小组发布了一个惊人的消息。

李淼的文章关于全息暗能量（附：韩文博文，关于北京与Horava）2009年05月31日10:46:23分类：未分类昨天看到曾经获得理论物理博士学位，现在在做应用研究开发的“吊床物理学家”Johannes Koelman的博文：Holographic Dark Universe该博文讨论全息暗能量。

打开一看，我本来以为他有什么新想法，原来还是类似2000年Scott Thomas就有的想法。

先看量子场论是如何估计真空能量密度的。

在量子场论中，一个最小的空间胞的体积是，其中是普朗克长度。

普朗克长度出现在这里很“自然”，因为单从量子场论的角度看，我们没有理由不相信普朗克长度是量子场论成立的最小尺度。

如果我们认为的确可以有这个最小空间体积，那么在这个体积中的一个量子的最大能量是，其中是普朗克质量，在自然单位制中，能量密度就是，一个非常大的量。

那么，宇宙学观测告诉我们什么？暗能量或真空能量密度和临界密度是一个量级，也就是，H是哈勃常数。

哈勃常数比普朗克质量小大约60个量级，所以量子场论允许的真空能密度比观测值大120个量级，这就是Koelman嘴里的物理学家们的euphemistic statement：宇宙学常数问题。

我想起翟永明的一本书，叫《最委婉的词》，宇宙学常数问题是物理学家最委婉的提法吧。

用Koelman的形象说法，暗能量密度大约是一个一千公里立方体内含有一个普朗克能量（克）。

将公式中的一个变成普朗克长度倒数，H变成宇宙大小L的倒数，这个公式告诉我们，在体积之内，有一个普朗克能量。

我们再看Koelman如何建议从量子场论的过度到的。

这需要将两个普朗克长度因子变成两个宇宙尺度因子。

第一步，根据全息原理，宇宙中的自由度个数不是一个宇宙体积含有很多普朗克体积，即，而是Bekenstein-Hawking自由度个数，这样，我们就将一个普朗克长度变成了宇宙尺度。

进一步，每个自由度的能量不该是普朗克能量，而是其Compton波长为宇宙尺度的能量，这样就将第二个普朗克长度换成宇宙尺度。

文汇报/2013年/8月/31日/第009版文汇周末·焦点“科普狂人”李淼：给《三体》挑物理学硬伤“《三体》系列”是一部史诗规模的硬科幻作品，在中国大陆累计销量超过40万册，被公认为是中国科幻文学的里程碑之作，为中国科幻确立了一个新高度本报首席记者吴越8月26日，中国科学院理论物理研究所研究员李淼发布一条微博：“《三体中的物理学》写了9万字了，计划中还有3章待写，也许4章。

无论如何，最后一章是黑暗森林。

”消息发布后，《三体》粉丝自然是一派欢腾。

《三体》系列故事讲述地球文明在宇宙中的兴衰历程。

作者刘慈欣。

其英文版权被北美权威科幻类出版社——“托尔(Tor)”购买，2013年7月，托尔出版社在它的官方网站上宣布即将推出“第一部翻译成英文的中国科幻作品”的消息。

受《星球旅行的奥秘》启发其实，《三体中的物理学》与《三体》英文版、《三体》影视改编、豆瓣音乐小站“《三体》非官方配乐”不是一回事。

它不是小说《三体》“下”的蛋，它和《三体》之间的关系更像是箭与靶。

简单来说，李淼择出作者刘慈欣在《三体》中涉及物理科学的科幻设定，逐一分析它们“靠谱”还是“不靠谱”。

根据李淼向本报记者透露的计划，该书总篇目约二十章，每章都紧贴住《三体》中的一个物理学幻想展开阐释和议论，每篇约六七千字。

李淼不否认他被《三体》的魅力打动，但并未笔下留情。

他说：“《三体》中的科学破绽占50%甚至更多，这就是我们和西方科幻作品之间的差距。

”当然，拉远了看，《三体中的物理学》还是“《三体》系”周边衍生产品中的一员。

可以理解为，科学家李淼以这套迄今在中国出版的影响最大的华语科幻小说为跳板，借《三体》之名，行科普之事。

与《三体》的邂逅在2008年，合肥。

中国科技大学校园内一家今天已不复存在的书店新进了一批书，来不及上架，暂且堆在地板上。

客座教授李淼恰好走进来，看见其中一叠《三体》。

在那之前，李淼听说过刘慈欣的《球形闪电》。

很自然地，他抄起一本读了下去。

有关元宇宙的英语作文Title: Exploring the Metaverse: A New Frontier inDigital Realms。

The concept of the Metaverse has captured the imagination of technologists, futurists, and dreamers alike. It represents a virtual universe where people can interact, create, and explore in ways that transcend the limitationsof the physical world. In this essay, we will delve intothe intricacies of the Metaverse, exploring its definition, current applications, and potential implications for society.Firstly, what exactly is the Metaverse? Coined byauthor Neal Stephenson in his 1992 science fiction novel "Snow Crash," the Metaverse refers to a collective virtual shared space, created by the convergence of virtually enhanced physical reality and persistent virtual reality. Essentially, it is a digital realm where users can interact with each other and digital objects in real-time, oftenthrough the use of virtual reality (VR) or augmentedreality (AR) technologies.Today, the Metaverse is not merely a speculative concept but a burgeoning reality. Companies like Facebook (now Meta Platforms), Epic Games, and Roblox are actively developing platforms that aim to realize this vision. For instance, Facebook's Horizon and Meta Quest platforms allow users to socialize, play games, and attend events invirtual environments. Similarly, Epic Games' Fortnite has evolved beyond a mere video game into a social space where players can participate in concerts, movie screenings, and other live events.One of the most promising aspects of the Metaverse is its potential to revolutionize various industries. In the realm of entertainment, virtual concerts and immersive experiences are redefining how artists engage with their audiences. In education, virtual classrooms offer new opportunities for interactive learning and global collaboration. Moreover, the Metaverse has implications for commerce, with virtual storefronts and digital goodsbecoming increasingly prevalent.However, alongside its potential benefits, the Metaverse also raises important questions and concerns. Privacy and data security are paramount, as users' digital identities and interactions must be safeguarded against exploitation and misuse. Moreover, there are concerns about the potential for the Metaverse to exacerbate existing inequalities, particularly in terms of access and representation.Despite these challenges, the Metaverse represents a new frontier of human experience, limited only by our imagination and technological capabilities. As we continueto explore and develop this digital realm, it is essentialto ensure that it remains inclusive, equitable, and aligned with our collective values and aspirations.In conclusion, the Metaverse holds the promise of a boundless digital frontier where people can connect, create, and explore in ways never before possible. While it isstill in its infancy, the rapid pace of technologicalinnovation suggests that the Metaverse will play an increasingly significant role in shaping the future of human society. As we navigate this brave new world, let us strive to harness its potential for the betterment of all.。

Shut Up and CalculateShut Up and Calculate （闭上嘴，动笔去算）最近大神Nima在康奈尔大学做了一个面向公众的讲座，题目就是“Three Cheers for Shut Up and Calculate in Fundamental Physics”。

比较遗憾的是，网上并没有讲座的录像，也没有讲座的讲义。

不过很庆幸的是在Peter Woit 和Motl的博客上都有对这个讲座的评论。

这两个人是死对头（Tom and Jerry那种），经常在博客上互相抨击(Motl是大神级别的弦论学家，Peter Woit是“臭名昭著”的反弦论主义者)。

Motl自称虽然也没有看过Nima的讲座，但是通过他们多年的交流和交情，他可以推测讲座的内容，并写了一篇长文“2.7 cheers for shut up and calculate”。

文章很有意思，暗合我内心对物理的看法的一种转变。

这里算是对那篇博文某种程度上的“转译”还有就是对自己想法，心境的一种记录。

所以我只代表自己对文章的理解，任何可能的错误都来自我的偏见，感兴趣的朋友可以看Motl的原文还有如果找到Nima的讲座，欢迎@我。

先录最近微博上看过的一个段子：“费曼说，相对论流行以后，很多哲学家跳出来说“坐标系是相对的，这难道不是最自然的哲学要求吗？这个我们早就知道了！”可是如果你告诉他们光速在所有坐标系下不变，他们就会目瞪口呆。

所以真正的科学家其实比“想象家”更有想象力。

”(转载李淼的微博)再录一个我自己亲身经历的段子：一次上信息课的时候，教授不知怎么就谈到弦论学家了。

学生问他们是做什么的，教授说他们算东西(they compute)，然后大家就一起会心的笑起来。

我知道教授的弦外音是，弦论学家的工作往往是计算很复杂的东西，但是对于他们算的东西意义可能并不完全知道。

那个教授我很喜欢的，虽然不是费曼的嫡传学生，但是他是在费曼还在的加州理工毕业的。
