训学斋规读书有三到 EssaysOf Studies

朱熹 · 训学斋规

读书有三到

余尝谓读书有三到，谓心到，眼到，口到。心不在此，则眼不看仔细，心眼既不专一，却只漫浪诵读，决不能记，记亦不能久也。三到之中，心到最急。心既到矣，眼口岂不到乎？

论语 · 为政

子曰：「学而不思则罔，思而不学则殆。」

子曰：「温故而知新，可以为师矣。」

Francis Bacon · Essays

Of Studies

Studies serve for delight, for ornament, and for ability. … Read not to contradict and confute; nor to believe and take for granted; nor to find talk and discourse; but to weigh and consider. Some books are to be tasted, others to be swallowed, and some few to be chewed and digested.

Reading maketh a full man; conference a ready man; and writing an exact man.

功能Features

一个工具，走完读书的全过程

One tool for the whole life of a book

从打开一本书，到划下句子、弄懂它、整理它、考自己，最后和别的书的笔记放在一起。

From opening a book to marking it up, understanding it, digesting it, testing yourself, and keeping it next to everything else you've read.

读Read1 / 7

PDF、电子书、Markdown，打开就接着读

PDFs, e-books and Markdown, right where you left off

把文件拖进窗口就能读。没有加密的 EPUB 也行，包括苹果图书里自己导入的书。每次打开都回到上次读到的那一段，PDF 连缩放都记得。

Drag a file into the window and start reading. DRM-free EPUBs work too, including books you added to Apple Books yourself. Every time you open it you're back at the paragraph you stopped at, zoom level and all.

  • 电脑是深色模式，阅读器也变深色，书页照旧白纸黑字
  • 底部的小胶囊记着今天读了多久
  • Simple mode keeps a few icons; Pro mode puts every button in the toolbar

拖一下就高亮，想法随手记

Drag to highlight, jot a thought anywhere

松开鼠标就划好了。红、黄、蓝三种颜色可以起名字，比如「有感触」「喜欢的句子」「要查的」，所有书通用。给一句话写想法，或者在页面任何地方贴一张随想便签。

Let go of the mouse and it's highlighted. Name the three colors however you like, say “Moved me”, “Favorite lines” and “To look up”, and they work across every book. Add a thought to a sentence, or stick a note anywhere on the page.

  • 写了想法的高亮，底下有一条橙色线
  • 随想写完收成小便签，不挡正文，还能拖到别处
  • iPad 上用 Apple Pencil 在字上划过就高亮
  • 在想法框里按两下 Fn，用 Mac 的听写说话输入
  • Highlights with a thought get an orange underline
  • Sticky notes fold into a small square so they never cover the text
  • On iPad, stroke the words with Apple Pencil to highlight
  • Press Fn twice to dictate a thought on a Mac

论语 · 学而 / 为政

子曰：「学而时习之，不亦说乎？有朋自远方来，不亦乐乎？人不知而不愠，不亦君子乎？」

子曰：「温故而知新，可以为师矣。」

想法每次重读都会划到新的地方，大概就是这个意思。

子曰：「学而不思则罔，思而不学则殆。」

Thoreau · Walden

I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived.

Our life is frittered away by detail. … Simplicity, simplicity, simplicity!

ThoughtMy inbox, my tabs, my PDFs. Three is the right number of times to say it.

随想STICKY NOTE 第二遍读的时候，和《学记》对照着看。 Second read: compare with the “Economy” chapter.

  1. 观点只用注意力机制，不用循环网络和卷积，也能把机器翻译做好。第 1 页
  2. 方法多头自注意力：每个词同时从几个角度看句子里的其他词；再用位置编码记住词序。第 4 页
  3. 数据WMT 2014 英译德 28.4 BLEU，比以前最好的结果高出 2 分多。第 8 页
  4. 结论能并行计算，训练快得多：大模型在 8 块 GPU 上训练 3.5 天。第 8 页
  1. IdeaAttention alone, with no recurrence or convolution, is enough for strong machine translation.p. 1
  2. MethodMulti-head self-attention lets each word look at the others from several angles; positional encoding keeps word order.p. 4
  3. Data28.4 BLEU on WMT 2014 English–German, over 2 points above the previous best.p. 8
  4. ConclusionIt parallelizes, so it trains far faster: the big model took 3.5 days on 8 GPUs.p. 8

Studies serve for delight, for ornament, and for ability.

读书可以带来乐趣，可以增添文采，也可以增长才干。

Read not to contradict and confute; nor to believe and take for granted; nor to find talk and discourse; but to weigh and consider.

读书不是为了反驳，也不是为了轻信，更不是为了找谈资，而是为了掂量和思考。

第 2 页

Some books are to be tasted, others to be swallowed, and some few to be chewed and digested.

有的书尝一尝就行，有的书可以整个吞下，只有少数的书要细细嚼、慢慢消化。

Page 1

余尝谓读书有三到，谓心到，眼到，口到。

I have always said that reading needs three things present: the mind, the eyes and the mouth.

心不在此，则眼不看仔细，心眼既不专一，却只漫浪诵读，决不能记，记亦不能久也。

If the mind is elsewhere, the eyes don't look closely. With neither focused, you only recite aimlessly, and you will never remember it, or not for long.

Page 2

三到之中，心到最急。心既到矣，眼口岂不到乎？

Of the three, the mind matters most. Once the mind is there, how could the eyes and mouth not follow?

整理Digest5 / 7

笔记一键整理成要点、复习题和思维导图

Your notes become key points, review questions and a mind map

点「导出」，先存一份原始汇总，再另存 AI 整理版和一张思维导图。AI 整理的是你自己划的句子和写的想法：最重要的几条、按主题归类、附原话和页码，还有复习题。

Hit Export and you get your raw notes, plus an AI digest and a mind map. The AI works from what you marked and wrote: the few points that matter most, grouped by theme with the original lines and page numbers, and review questions.

  • 导出成 Markdown，存在笔记文件夹里
  • 「复制汇总」粘到 Google Docs，标题、引用、底色都在
  • 笔记没变时直接用上次的结果，不重复花钱

考Quiz6 / 7

考考我：用你自己的笔记出题

Quiz me: questions built from your own notes

AI 按你划过的句子出题，你用自己的话回答，它告诉你哪里说对了、哪里可以补。满意的回答存成「我的理解」。可以考一本书，也可以考书架上的一个主题。

The AI writes questions from the lines you marked. You answer in your own words, and it tells you what you got right and what to add. Save the answers you like as “My understanding”. Quiz one book, or a whole topic on your shelf.

  • 可以只考一种颜色，比如只考「要查的」
  • 作者最喜欢的用法：把生词标成蓝色，选中问 AI 词义和词源，读完让「考考我」专门考这些词
  • Quiz just one color, for example only “To look up”
  • The maker's favorite trick: mark unfamiliar words in blue, ask the AI for their meaning and origin, then let Quiz me test you on just those words
考考我 · 论语Quiz me · Walden 只考Only 要查的To look up

第 2 题 / 共 5 题

Question 2 of 5

「学而不思则罔，思而不学则殆」里，「罔」和「殆」是什么意思？用你自己的话说。

In “I wished to live deliberately”, what does “deliberately” mean? Say it in your own words.

你的回答Your answer 罔：光读不想，越读越糊涂，什么也没得到。殆：光想不读，心里没底，容易出错。 On purpose. Choosing how to live instead of just drifting along.

说得对。「罔」是迷惑、没有收获；「殆」一般解作危险、不踏实，也有人解作疑惑。你说的「心里没底」把两种说法都照顾到了。

Right. Thoreau means living with intention and full attention, which is why he goes on to say he wanted to “front only the essential facts of life”.

专注读 10 分钟，
点亮一颗星。

Read with focus for 10 minutes. Light up a star.

不打卡，也不扣分。专注读满 10 分钟（可以改成 15、25、45 分钟），星空里就多一颗星，读得越久星星越大。读完一本书，划过一道流星。第一颗星亮起之前，首页上看不到它。

No streak shaming, no penalties. Read for 10 focused minutes (or 15, 25, 45) and a star appears; longer sessions make bigger stars. Finish a book and a meteor crosses the sky. Until your first star, the sky stays hidden.

  • 前 7 天每颗星都放满屏烟花，之后是每天第一颗和里程碑
  • 鼠标放到星星上，看是哪天、读的哪本书
  • 星空能存成图片，发给朋友

笔记安全Your notes

笔记是你的，存在你自己的文件夹里

Your notes are yours, kept in your own folder

存成普通文件

Plain files

第一次用时选一个笔记文件夹，笔记就存成里面的普通文件。放在 Google Drive 或坚果云里，自动备份到云端，换一台电脑也在。清理浏览器缓存也不会丢。

Pick a notes folder once, and your notes are saved there as ordinary files. Put it in Google Drive or iCloud Drive and it's backed up and follows you to another computer. Clearing your browser won't touch it.

网站只负责送来阅读器

The site only delivers the reader

书和笔记不会传到网站上。不用注册账号。打开过一次以后，断网也能打开（AI 功能要联网）。Chrome 还能把它装成一个单独的 App。

Your books and notes are never uploaded to the site. There's no account. After the first visit it opens offline too (AI features need a connection), and Chrome can install it as its own app.

用 AI 时才发出文字

Text leaves only when you use AI

只有点了 AI 功能，要处理的那部分文字（选中的句子、整份文档或你的笔记）才发给 AI：国际版用 Claude，大陆版用 DeepSeek。邀请码只用来开通 AI。

Only when you use an AI feature is the text it needs (a sentence, the document, or your notes) sent to the AI: Claude in the international version, DeepSeek in the China version. Invite codes just switch AI on.

怎么开始Get started

三步，大约两分钟

Three steps, about two minutes

  1. 1

    用电脑或 iPad 打开阅读器

    Open the reader on a computer or iPad

    电脑上用 Chrome、Edge 或 Safari，iPad 上用 Safari。不用下载、不用安装。

    Chrome, Edge or Safari on a computer; Safari on iPad. Nothing to download or install.

    beta.anqapdf.app
  2. 2

    选一个笔记文件夹

    Choose a notes folder

    建议在 Google Drive 或坚果云里新建一个，比如「PDF 笔记」。以后笔记都存在这里。

    Make one in Google Drive or iCloud Drive, say “PDF notes”. Everything you write is saved there.

    选择笔记文件夹Choose notes folder
  3. 3

    粘贴邀请码，AI 就配好了

    Paste an invite code to switch on AI

    也可以填你自己的 API 密钥。第一次用？首页有一份新手教程，一页教一个功能，大约 10 分钟。

    Or use your own API key. New here? The home screen has a built-in tutorial, one feature per page, about 10 minutes.

    粘贴邀请码，比如 RN-7K3M-Q9XP-2WDFPaste your invite code, e.g. RN-7K3M-Q9XP-2WDF

还没有邀请码？请已经在用的朋友点阅读器左下角的「推荐给朋友」，把专属链接发给你，用电脑打开就自动领到邀请码。不填也能先用：读书、高亮、写想法、导出笔记都不需要 AI。

No invite code yet? Ask a friend who uses it to tap “Recommend to a friend” in the bottom-left corner and send you their link. Open it on a computer and your code is set up automatically. You can also start without one: reading, highlighting, notes and exports don't need AI.

读 PDF 时，越用越觉得手上的软件不顺手，干脆让 Claude 帮我做了一个自己用的。现在它几乎每天都在改，很多改动来自阅读器左下角的「吐槽一下」。你提的意见做好了，下次打开就会告诉你。
