James while John had had had had had had had had had had had a better effect on the teacher

“**James while John had had had had had had had had had had had a better effect on the teacher**”這個英文句子是用來說明用词歧義和标点符号的重要性；標點符號的作用就是代替口語中的語調、重音和停頓。在探討人類如何處理資訊的研究中，常用這句話来說明讀者會借助標點符號來理解句子的意思，尤其在掃讀多行文字時更是如此。

## 句子的背景和意思

故事起自有兩個學生，James（詹姆斯）和John（約翰）。他們曾經需要在一個英語考試上描述一個曾經着涼的人。約翰寫的句子是“The man had a cold”，這句在文法上不正確；而詹姆斯寫的句子在文法上正確：“The man had had a cold”。老師於是註記「由於詹姆斯的答案是正確的，所以它對於老師有一個較好的效果。」

如果加了標點符號，這句句子會比較清楚：

> James, while John had had "had", had had "had had"; "had had" had had a better effect on the teacher.
>
>

> （翻译：詹姆斯在当约翰用“had”时用了“had had”，老师认为“had had”的效果更好。）
>
>

如果重排句子，意思會更清楚：

> James had had "had had", while John had had "had"; "had had" had had a better effect on the teacher.
>
>

> （翻译：詹姆斯用了“had had”，而约翰用了“had”，老师认为“had had”的效果更好。）
>
>

應用

這句子可以作為一個文法遊戲或一條考試題目，考生需要赋予合适的標點符號來明晰句子意思。汉斯·赖申巴赫（Hans Reichenbach）在1947年出版的《符号逻辑要素》一书中用了一个类似的句子（“John where Jack...”），給讀者作為練習，以说明语言的不同层次，例如目標語言及元語言，其用意是让读者为句子添加所需的标点符号，使之具有语法意义。

在說明人們如何理解環境中不同信息的意義是，这个句子被用来证明看似随意的决定能极大地改变其意义。类似于句子中标点符号的变化如何使老師時而喜欢詹姆斯的作品，時而喜歡约翰的作品。例子：「James, while John had had "had," had...」與「James, while John had had "had had,"...」。

这句话也是为了显示「had」（完了）的语义模糊性，也是为了说明用字和提字的区别。也有人以它为例，说明语言的复杂性、语言的解释及其对人的认知的影响。

为了让读者清楚地了解句法结构，这个句子至少要求两个短语之间用分号、句号、横线分开。不过，贾斯珀·福尔德的小说《失落的情节之井》还是采用了这一短语的变体，以说明即使是标点良好的写作也可能产生混乱：

> ""Okay," said the Bellman, whose head was in danger of falling apart like a chocolate orange, "let me get this straight: *David Copperfield*, unlike *Pilgrim’s Progress*, which had had 'had', had had 'had had'. Had 'had had' had TGC’s approval?""
