Every clause, every punctuation mark, every plot twist, puzzle, and factoid is engineered precisely to flatter our intelligence. 每一个从句，每一个标点符号，每一个曲折的情节、谜团和花絮都是为谄媚读者的智商而精心设计的。
Punctuation is "the use of spacing, conventional signs, and certain typographical devices as aids to the understanding and the correct reading, both silently and aloud, of handwritten and printed texts." Another description is: "The practice, action, or system of inserting points or other small marks into texts, in order to aid interpretation; division of text into sentences, clauses, etc., by means of such marks."
