核心畫面
Picture the book on a student's desk — the one the whole class works from, laying a subject out chapter by chapter, in the order it is meant to be learned. Everything in it is the tidy, standard version, with the mess taken out. Because of that, English can turn the word around and use it for real things too: something is textbook when it comes out looking exactly like the picture in that book.

可以想成學生桌上那本課本：全班一起用的那一本，把一門學問一章一章、按照該學的順序攤開來。裡面的東西都是整理過的標準版本，雜訊都被拿掉了。也正因為這樣，英文可以把這個字倒過來用在真實的事情上——做出來的結果，跟課本上畫的那張圖一模一樣。From the word’s history
Textbook as a compound dates from 1779, meaning 'a book used by students as a standard work for a branch of study'; an earlier 1730 use was for a book printed with wide line spacing so a student could write notes or a translation between the lines. The adjective sense 'typical of a textbook' appears in 1916. Text itself goes back through Old French to Latin texere 'to weave'.
textbook 這個複合字 1779 年出現，指「學生拿來當標準讀本用的書」；更早在 1730 年，它指的是行距印得很寬、方便學生在行間寫筆記或翻譯的書。形容詞「典型的」這層意思要到 1916 年才出現——所以「像課本一樣標準」確實是從那本實體的書長出來的。text 本身經古法文來自拉丁文 texere（編織），把字句「織」成一篇文章。

像課本示範的那樣標準
課本裡的例子永遠是最乾淨、最沒有意外的版本。把這個印象拿回來形容現實發生的事，就成了「教科書等級的示範」——這個字放到名詞前面，整本書的標準感就跟著過去了。
