你舉的這些句子全部都是文法錯誤的句子．然而，應該用"doesn't"卻用"don't"的情況其實很常見．"He don't love you"是一張音樂專輯的名稱．參考：http://en.wikipedia.org/wiki/He_Don't_Love_You"I don't care if the sun don't shine." 是一句老歌詞．以上兩個例子雖然文法有誤，但仍然有人使用．如果你是在書上看到的話，通常用來表達說話者的教育程度不高或是社會階層低下．另外一種說法，有人認為那是一種方言的表達方式．參考：http://wsu.edu/~brians/errors/he_don't.htmlIn formal English, "don't" is not used in the third person singular； but "he don't have no money," though common in certain dialects, is nonstandard on two counts: it should be "he doesn't" and "any money." The same is true of other forms: "she don't" and "it don't" should be "she doesn't" and "it doesn't."在正式英語中，第三人稱單數不使用"don't"為助動詞．雖然在某些特定的方言中"he don't have no money," 意思普遍聽得懂，但並不是標準英語．這個句子有兩個文法上的錯誤，正確的句子應該是"he doesn't have any money." 而其他的第三人稱單數也都是用"doesn't"才正確．有時候在文學表現上，如詩歌或特意描寫人物的風格時文法就沒有一定的鐵則．語言是活的．文法是用來讓人學習正確用語的一套標準，我們知道”he don't”是錯誤的，雖然看得懂聽得懂，但是要不要用是個人的選擇．
