老登常谈（双语版）
我把这些年翻来覆去跟学生讲的那几套话，提炼出来、总结成 12 个系列、共 51 段，是为以后双语授课、甚至纯英语授课做准备。
说实在的，这些话用中文，我张嘴就能说出来；可一换成英语，表达起来就费劲。好在以前我在斯坦福大学的 Code in Place 上，2024 年、2025 年两次给人讲过 Python——讲咱们专业相关的内容我倒还撑得住，顺便也把英语练熟了点。
有时候孩子们在路上撞见我在背英语，其实不是那么回事：我不是在背英语，而是在准备一些讲课也用得上的东西。
每段先给英文、后给中文，都是三四句的完整段落，一分钟左右能读完、能背下来；末尾标了出处，尽量用公众号文章链接，没发公众号的给了博客链接。用法很简单：照着英文开口练，用中文核对意思，需要查原文就点出处链接。
系列一：心态与节奏
1. 徐徐图之
英：Don't chase quick results — take it slow, step by step you go. When you move at a steady pace, you stay calm and bring out your best. Slow and steady wins the day; rushing only gets in the way.
中：做事情不要急功近利，要徐徐图之——慢慢来，一步一步谋划。你慢慢做，人就从容、不紧张，反而能把实力发挥得更好。急不来、催不得，稳扎稳打才靠得住。
出处：《建议大学生朋友们做事情要徐徐图之，不要急功近利》（博客）
2. 不能走极端
英：Too much hope and too much fear are the same trap — both are extremes. Quick victory or quick defeat, the mistake is the same. Stay in the middle, keep your balance, and you can still think straight.
中：不管是"速胜论"还是"速败论"，极端的乐观和极端的悲观，本质都一样——都是极端。所有的事儿都相似，不能走极端。保持在中间，才留得住思考的余地。
出处：《建议大学生朋友们做事情要徐徐图之，不要急功近利》（博客）
3. 慢不是磨洋工
英：Going slow is not being lazy, and it's not stalling on purpose. It means a steady rhythm, a clear order, real results. Slow is not weak; slow is steady and sure.
中：慢不是磨洋工，不是故意拖沓，而是张弛有度、工作有序、成果有效。这个"慢"是稳，不是懒；是节奏，不是拖延。
出处：《建议大学生朋友们做事情要徐徐图之，不要急功近利》（博客）
4. 心态最重要
英：Nothing matters more than a calm mind and a cheerful heart. The moment you panic, your rhythm falls apart, and your ability slips away. Stay calm and keep smiling — that's where real strength starts.
中：心态好、心情好，天天乐呵呵，比什么都重要。心态一慌，节奏就乱了，原本能发挥出来的实力也发挥不出来。稳住神、笑一笑，比什么都值钱。
出处：《建议大学生朋友们做事情要徐徐图之，不要急功近利》（博客）
5. 将以有为也
英：When trouble comes, keep your strength — that leaves a way out. Some things simply can't be hurried. Hold on, stay alive, and one day you can still make something of it. As an ancient general said: I meant to do something with this later.
中：遇到困难，保存有生力量，就总留得一线生机。有些事情急不来，要徐徐图之，留得青山在，才能"将以有为也"。南霁云那句话，说的就是这个道理。
出处：《建议大学生朋友们做事情要徐徐图之，不要急功近利》（博客）
系列二：认知与谦逊
1. 心有外物而不化
英：General Qi Jiguang, in his book on training soldiers, warned: people cling to what they already know, and call their old ways the best. Once your mind is full of old habits, you naturally push away the new. Let go of the old, and you start to grow.
中：戚继光在《纪效新书》里说，人容易"心有外物而不化，自恃旧习以为佳"——心里装了旧东西，就不愿接受新的，还总觉得自己那套旧经验最好。不肯放下旧的，就学不进新的。
出处：《读〈纪效新书〉有感》
2. 别被已有认知束缚
英：Don't let what you already know lock you in. The real danger is not that you know too little — it's thinking that what you know is everything. A closed mind hurts more than an empty one.
中：人不能被自己已有的认知给束缚住。最要命的不是知道得少，而是觉得自己知道的就已经是全部，再没有别的可能。这种自以为"全知道了"，比无知更害人。
出处：《读〈纪效新书〉有感》
3. 知道自己知道得太少
英：After years of study and years of real life, the one thing I'm sure of is that I still know far too little. The more I learn, the more I see how small my corner is. Being humble isn't weakness — it's the plain truth.
中：念了些年书，闯了几年江湖，我大概能确定知道的，就是自己知道的实在太少了。越学越觉得自己那点认知小得可怜。这种谦卑不是示弱，是实话。
出处：《读〈纪效新书〉有感》
4. 别急着否定
英：When someone says you're wrong, the reflex to argue back is just an animal guarding itself. We reject first and nitpick later. Rise above it — listen first, then judge. That's what lifts you above the animal.
中：看见别人否定自己，第一反应是反驳、挑刺，这其实是动物性的自我保护。遇事先否定、见什么都挑刺，是本能在作怪。能超脱一点，先听听、再想想，才高级。
出处：《读〈纪效新书〉有感》
系列三：提问与沟通
1. 别问"在吗"
英：Don't send a message that only says "Are you there?" — it wastes everyone's time and makes the other person guess. Say what you need, straight and clear. Clear beats polite, every time.
中：发消息别只丢一句"在吗"，那是对双方时间的双重消耗，还让人家猜你要干什么。有事直接说，把话说清楚，就是最大的得体。清楚，比客气更管用。
出处：《高校教师建议大学新生：有事直接说，别问在吗》（博客）
2. 三句话说清楚
英：When you ask for help or report something, three things are enough: what it is, how it touches you, and why you ask this person. You don't need to be fancy — just don't leave people guessing. Say it plainly, then move on.
中：找人帮忙、问问题、汇报事情，说清三件事就够：什么事、跟你什么关系、为什么找到对方。不怕说得不够好，就怕什么都不说、让人猜。说清楚，就走人。
出处：《高校教师建议大学新生：有事直接说，别问在吗》（博客）
3. 先搜再问
英：Before you ask, search first — or ask an AI — and sort out the basics. Then bring that first understanding to the table. If you open your mouth before you lift a finger, people will wonder why you didn't even bother to look.
中：遇到不懂的，先自己搜，先问大模型，把信息理一理，再拿着初步认知去问人。你不动手先张嘴，人家会想：你连搜都懒得搜？自己先走一步，再开口。
4. 效率优先
英：When we talk, efficiency first, polish second. Get your point across, and everyone feels better. A short, clear word beats a long, flowery one.
中：沟通这件事，效率优先，得体其次。先把事说清楚，效率上来了，大家都舒服。快而清楚的一句话，胜过绕来绕去的客套。
出处：《高校教师建议大学新生：有事直接说，别问在吗》（博客）
5. 想说不敢说，不是内向
英：An introvert can speak when needed — they just don't want to when it's not necessary. If you want to speak but dare not, that's not your personality; you just haven't learned how. Don't hide behind a label.
中：内向的人需要表达时照样能说，只是不需要时不想说。如果你是想说却不敢说，那可能不是性格，是还没学会开口。别拿"我内向"当挡箭牌。
出处：《高校教师建议大学新生不要用内向的标签影响自己的沟通效率》
系列四：对自己诚实
1. 别把听话当必然
英：Don't assume the rules are always fair, that grown-ups are always right, or that obedience always pays. Growing past the student mindset doesn't mean turning cold — it means not being naive. Keep your warm heart; drop the innocence.
中：别以为规则一定公平，别以为大人一定对，别以为听话就一定有回报。去掉一些学生气，不是变冷漠，而是别太天真。该有的古道热肠还要有，只是别再傻乎乎。
2. 大人不见得更有智慧
英：Most adults are not wiser than children — they just have more experience and habits, and know better how the world runs. That's all. So don't take every word they say as sacred.
中：大多数大人不见得比孩子更有智慧，只是有更多经验和习惯，对社会的运行逻辑更熟。如此而已。所以别把大人的每句话都当圣旨。
3. 幻想和期待
英：A fantasy is believing things will get better by themselves. An expectation is knowing you must do something to make them better. College is full of things worth expecting — just don't let expectation quietly turn into fantasy.
中：幻想是以为事情会自动变好，期待是知道自己要去做些什么让它变好。大学里值得期待的东西很多，但别把期待过成了幻想——等着天上掉馅饼，是掉不下来的。
4. 真热爱，还是只想赢
英：Ask yourself clearly: do you truly love this thing, or do you just want to win through it and feel you belong? Letting someone else win for you is cheap joy. Real love lasts; borrowed victory doesn't.
中：分清楚你是真的热爱一件事，还是只想通过它赢、想要一种归属感。让别人替你赢，那种快乐来得廉价。真正的热爱撑得久，借来的胜利撑不久。
出处：《高校教师建议大学生朋友能对自己诚实负责地度过大学生活》
5. 大学是起点，不是终点
英："Once you get into college, you can relax" is one of the biggest lies you'll ever hear. College is where the competition is sharpest and the free time is most — that's where the gap widens. This is a starting line, not a finish line.
中："到了大学就轻松了"是你可能听过的最大的谎。大学里竞争最激烈、可支配时间最多，你和别人的差距，很多是在大学拉开的。这是起点，不是终点。
系列五：情绪与决定
1. 别把赌气当决定
英：Before you decide, ask yourself: do I really want this, or am I just acting out of spite? Every time you stop yourself from turning a feeling into a choice, you take charge of your life. That one question saves a lot of regret.
中：做决定之前问自己一句：我到底是真的想这么选，还是只是在赌气。每一次能拦住自己把情绪当成决定，都是对自己负责。这一句话，能省掉很多后悔。
出处：《高校教师建议大学新生尽量避免赌气-学会基于判断而不是情绪来做决定》
2. 赌气不划算
英：Failing a subject and then quitting isn't "I tried and couldn't" — it's "I didn't try, so I couldn't." The second excuse is easier to swallow, but it costs far more. You're not protecting your pride; you're paying for it.
中：一门课没考好就索性不学，那不是"努力了还不行"，而是"没努力所以不行"。后一个说法好接受，但代价其实更大。你不是在保面子，是在为面子付账。
出处：《高校教师建议大学新生尽量避免赌气-学会基于判断而不是情绪来做决定》
3. 别把自己架起来
英：If you dig in out of spite, the homework still has to be done and the juice will still be there — but you've already boxed yourself in. Stubborn pride only locks you into a worse corner. Choose the better path, not the prouder one.
中：赌气到底，作业照样得做、果汁照样想喝，可话已经放出去了，自己把自己架在那儿，图什么呢？死要面子，最后只会把自己逼进更差的局面。
出处：《高校教师建议大学新生尽量避免赌气-学会基于判断而不是情绪来做决定》
系列六：通识与谦逊
1. 手里拿锤子
英：When all you have is a hammer, everything looks like a nail. Study one subject deeply, and you may feel it explains everything — but you're missing the thinking other fields have built for centuries. Knowing other tools exist keeps you humble.
中：手里拿着锤子，看什么都是钉子。学了一个学科，容易觉得它能解释一切，其实是忽视了别的学科早就积累了很久的思考。知道还有别的锤子、别的工具，才不容易因为无知而自大。
出处：《高校教师建议同学们进入大学之后适当补充各个学科的通识内容并且养成终身学习的习惯》
2. 别被工程成就冲昏头
英：A steam-engine master, however brilliant, could never dream of a nuclear reactor. It's not stupidity — those ideas simply aren't in his world. Be great at your craft, but stay humble before what lies beyond it.
中：一个蒸汽机师傅优化到极致，也想不到核反应堆。不是他笨，是他的知识坐标系里没有那些维度。手艺再精，也要对视野之外的东西保持敬畏。
出处：《计算机学科的同学尤其应该注重培养通识并且避免工程上的傲慢》
3. 无穷和无穷不一样
英：There are infinitely many whole numbers, and infinitely many real numbers — yet there are more real numbers. Learning that some infinities are bigger than others is a real jolt to intuition. Some things are true even when they don't feel true.
中：自然数无穷多，实数也无穷多，但实数比自然数更多。知道"有些无穷比另一些更大"，是数学带给你的一种认知冲击。直觉会骗人，逻辑不会。
出处：《高校教师建议同学们进入大学之后适当补充各个学科的通识内容并且养成终身学习的习惯》
4. 结构决定一切
英：The same carbon atoms make soft graphite or hard diamond. The atoms don't change — the arrangement does. Structure carries power, in matter and in teams alike. Change the layout, and you change the result.
中：同样的碳原子，排成石墨就软，排成金刚石就硬。原子没变，变的是结构。结构本身就带有力量——放在物质上、放在团队上，都一样。
出处：《高校教师建议同学们进入大学之后适当补充各个学科的通识内容并且养成终身学习的习惯》
5. 多看点字，少刷点视频
英：Short videos push your excitement bar so high that you can't sit through a long text. Words make you think; pictures just feed you. Read more, and you'll think deeper — it's a trade well worth making.
中：短视频把刺激的阈值拉得很高，习惯了就坐不住看长文。文字要你主动去想，画面直接喂给你。读得越多，想得越深，这笔账划得来。
出处：《高校教师建议同学们进入大学之后适当补充各个学科的通识内容并且养成终身学习的习惯》
6. 历史教训要学，角色不要拿
英：History holds wonderful patterns, but don't put yourself inside them. Don't become a loyal fan of some dynasty or group, as if their glory were yours. You are you — learn the lessons, don't take the roles.
中：历史里有很多精彩的规律，但别代入。不要成为某个王朝、某个群体的忠实粉丝，觉得跟人家荣辱与共。你是你自己，历史的教训要学，角色不要拿。
出处：《高校教师建议同学们进入大学之后适当补充各个学科的通识内容并且养成终身学习的习惯》
系列七：工具观
1. 工具是来帮你的
英：Tools are here to help you, not to scare you. Learn the basics first; then the bigger tools feel like a hand, not a weight. A tool you truly know becomes an extension of your hand.
中：工具是来帮你的，不是来吓你的。先把最基础的东西用熟，再上大工具，你会觉得它顺手，而不是压迫。真正学会了的工具，会成为你手的延伸。
2. 命令行不骗人
英：The command line tells you exactly what went wrong. A graphical screen just spins, pops up "failed," and stops. That's why I love the command line — it doesn't lie to you.
中：命令行报错就是报错，清清楚楚甩给你。图形界面转个圈，弹个框说"操作失败"，就完事了。所以我喜欢命令行——它不骗人。
3. 别把工具当信仰
英：Worshipping a brand like a religion is just another kind of worship — it turns a thing into a faith. Electronics are tools, not gods. Use them well, but never kneel to them.
中：把某个牌子当宗教来膜拜，和膜拜别的东西没两样，都是把东西当成了信仰。电子产品说到底就是工具，不是神。用好它，但别跪它。

系列八：外语学习
1. 语言要先用起来
英：Language is meant to be spoken and heard first, then read and written. The courage to open your mouth and not fear looking silly matters more than test scores. I was near the bottom in class, but I always dared to speak — and in the end, I used it best.
中：人类的语言本来就该先听说、后读写。敢开口、不怕丢人，比考试分数重要得多。我外语一路垫底，但一路敢说，最后反而用得最好。
出处：《高校教师建议大学生朋友们不要忽视外语的学习》（博客）
2. 学外语是为了讲好我们自己的故事
英：The richer a culture grows, the more it needs people who can speak foreign languages to tell its stories to the world. If you can't open your mouth, how will you tell others what's good about us? Learn the language, then tell the story.
中：本土文化越昌盛，越需要有外语能力，好把这些好故事讲出去。自己都张不开口，怎么给别人讲我们的好东西？把语言学好，把故事讲出去。
出处：《高校教师建议大学生朋友们不要忽视外语的学习》（博客）
3. 别信"不用学"那套
英：Anyone who says "you don't need to learn a foreign language" either has an agenda or is making excuses for their own laziness. Believe it, and only you pay the price. Don't let someone else's failure become your ceiling.
中：凡是劝你"不用学外语"的，要么别有用心，要么是拿这套说辞给自己找台阶。真信了，吃亏的只有自己。别拿别人的失败，当自己偷懒的理由。
出处：《高校教师建议大学生朋友们不要忽视外语的学习》（博客）
系列九：思维误区
1. 别急着证明自己对
英：The easiest trap is rushing to prove you're right and burning hours on it. The time you spend defending yourself is time you could have spent reflecting and improving. Winning an argument is rarely worth the cost.
中：最常见的坑，就是急于证明自己是对的，为这事浪费一大堆时间。时间都花在证明自己对上，反思的时间就没了。逞一时口舌之快，代价追不回来。
出处：《高校教师建议大学新生和家长都应该尽早防范的几种常见思维误区》
2. 错了就认
英：Everyone makes mistakes — memory slips, hands fumble, even masters mess up. Admitting a mistake is basic, and without it you can't improve. Refusing to admit a problem is the surest way to never fix it.
中：犯错再正常不过，记忆会出错，行为会失控，再高的高手都可能玩脱。认错是件很基础的事，不认错就不可能进步。不承认问题存在，就没法解决问题。
出处：《高校教师建议大学新生和家长都应该尽早防范的几种常见思维误区》
3. 别迷信权威
英：Just because someone is famous and successful doesn't mean you should swallow everything they say. Success often rides on luck and timing that even the winner can't see. Judge the idea itself, not the person who said it.
中：一个很有名、很权威的人说了啥，不见得就该信。成功里往往有运气和时代的成分，连成功者自己都未必看得清。判断一个观点，看它本身，别看是谁说的。
出处：《高校教师建议大学新生和家长都应该尽早防范的几种常见思维误区》
4. 从来如此，未必对
英："Everyone does it" and "it's always been this way" are not reasons — they're reflexes. A reasonable person gathers the facts and weighs the costs before deciding. Don't hand your judgment to the crowd or to habit.
中："别人都这样""从来如此"，这俩说法都没来由。该做的是理性判断，把资料收集齐，权衡好利弊再做决定。别把判断力外包给从众和惯性。
出处：《高校教师建议大学新生和家长都应该尽早防范的几种常见思维误区》
系列十：博弈与格局
1. 三种结局
英：Every game between people ends one of three ways: both lose, one wins and one loses, or both win. Most conflicts in life aren't zero-sum — there's usually a way to make the pie bigger. Look for the third way before you fight over the first two.
中：世间所有的博弈，归根结底逃不开三种结局：两败俱伤的负和、此消彼长的零和、相互成就的正和。生活里大多数冲突都不是零和的，先找第三条路，再谈争抢。
2. 别掉进负和
英：The saddest game is the negative-sum one, where everyone walks away worse. Two roommates feuding for half a year, teammates tearing each other down — no one wins, everyone loses. Talk early, before a small thing turns into mutual ruin.
中：最让人扼腕的是负和博弈，所有人都没占到便宜，收获远小于付出。室友较劲半年、队友互相拆台，谁也没落着好。小事早沟通，别等它变成互相伤害。
3. 把蛋糕做大
英：Real masters don't fight over how to cut a fixed cake — they find a way to make it bigger. Share your apple, share your orange, and both of you taste two flavors instead of one. Cooperation makes value that competition can't.
中：真正的高手，从不把自己困在零和的笼子里，而是想办法把蛋糕做大。你分我半个苹果、我分你半个橘子，俩人都能尝到两种味道。合作创造的价值，竞争给不了。
4. 别因怀疑而互相背叛
英：The prisoner's dilemma shows why people betray each other even when working together would be best for both. Cut off and unsure, each side plays "safe," and both end up worse. Trust, built slowly, is often the smarter long game.
中：囚徒困境说透了人为什么明明合作最有利，却还是互相背叛。被隔开、不确定对方会不会守约，各自"理性"地背叛，结果双双更惨。慢慢建立的信任，往往才是更聪明的长期打法。
系列十一：没有标准答案
1. 别迷信标准答案
英：The "standard answer" you memorized is just the best guess of its time — nothing more. History is full of "final answers" that turned out to be only stepping stones. Don't treat a textbook answer as the end of thinking.
中：你背下来的"标准答案"，不过是它那个年代最好的猜测，仅此而已。历史上很多"最终答案"，后来都被证明只是中间产物。别把教材答案当成思考的终点。
出处：《从志愿填报开始学生和家长都应该考虑到生活不一定要有标准答案》
2. 连太阳系都改过答案
英：Thirty years ago the solar system had nine planets; now it has eight, and someone wants to change it back. The solar system never changed — only our names and textbooks did. What changed is us, not the world.
中：三十年前太阳系有九大行星，现在改成八大，最近又有人要改回去。变的从来不是太阳系，只有人类的概念和教材。变的是我们，不是世界。
出处：《从志愿填报开始学生和家长都应该考虑到生活不一定要有标准答案》
3. 上学不是单行道
英：School is not a one-way road from college to PhD to teaching — that's just one path of many. Life is richer than a single fixed route. If you don't love your major, you may switch — just think it through first.
中：上学不是一条单行道，本科读研读博教书，只是很多条路里的一条。人生很丰富，不必非按某一条既定路径走。不喜欢自己的专业，深思熟虑之后，可以换。
出处：《从志愿填报开始学生和家长都应该考虑到生活不一定要有标准答案》
4. 别让别人的信息替你决定
英：The scariest thing is choosing your life by your parents' advice — advice that may be years out of date — while never trying what you actually want. Years later, you regret the road you didn't take. Look into it first, then choose.
中：最可怕的是按家里长辈的建议做了选择，可长辈的信息未必更新到最新；自己想做的事又没去尝试、没去弄明白。过了很多年，只剩后悔当初。先搞清楚，再决定。
出处：《从志愿填报开始学生和家长都应该考虑到生活不一定要有标准答案》
系列十二：大学怎么读
1. 别光靠听课
英：If you expect to learn everything from lectures, you'll be let down — some teachers just read slides. The real gift of college is that no one holds your hand anymore. Learning to find things yourself is the skill that matters most.
中：指望光靠听课就学到很多东西，这想法不靠谱——有的老师就是念 PPT。大学最关键的地方，恰恰是没人再带着你了。学会自己找东西学，才是最重要的能力。
2. 主动探索
英：In college, the most important thing is to find chances and dig into what truly interests you. What the textbook skips and the teacher doesn't teach, you have to learn on your own. That ability is what carries you to graduate school and beyond.
中：到了大学，最重要的是找到机会，以所学为基础，对自己感兴趣的方向去探索。课本没讲、老师没教的东西，得自己想办法去学。有了这能力，才能走得更远。
3. 用好免费资源
英：Your college gives you a library, online databases, journals, and talks — use them all. Textbooks are the oldest, journals fresher, conference papers freshest. One good talk can be worth more than a semester of class.
中：图书馆、电子文库、论文订阅、讲座，这些都是大学白给你的，都得用起来。教材最老，期刊新点，会议论文最新。一场好讲座，可能顶得上半学期的课。
4. 你是哪种人
英：On the journey west, the Monkey King runs everywhere to gather what it takes to solve a problem, while others wait for the problem to vanish by itself. Be the one who goes looking for answers, not the one who waits. The role is yours to choose.
中：取经路上，孙悟空是满世界去凑解决难题的资源，而有的人是等着难题自己消失。别做那个干等的人，去做那个主动找答案的人。你想当哪种人，自己选。
5. 事情本身最重要
英：Watch out when a system starts chasing the score instead of the thing itself — that's how good intentions get twisted. Grades, rankings, metrics — don't let the measuring stick become the goal. Keep your eyes on what truly matters.
中：当一个体系开始只盯着指标、而不是事情本身的时候，好事也会被扭曲。分数、排名、KPI，都别让"尺子"变成了"目的"。眼睛要盯在真正重要的事情上。
