固定句型，表示「與……無關」。主語為第三人稱單數時用 has（He/She/It has）。後面接名詞、代名詞或動名詞/V-ing 子句（e.g., cheating, being late）。亦可用強調語氣：have nothing whatsoever to do with…（完全無關）。另有延伸用法 want nothing to do with… 表「拒絕往來、完全不想扯上關係」，語意較強，勿混淆。

常見錯誤
✗
The rule has nothing to do to our class.
✓
The rule has nothing to do with our class.
固定搭配為 have nothing to do with + 名詞/代名詞/動名詞子句；介系詞必須用 with，不能用 to。
✗
He don't have nothing to do with it.
✓
He doesn't have anything to do with it. / He has nothing to do with it.
英文避免雙重否定；可用 has nothing…（單一否定），或 doesn't have anything…（否定助動詞 + anything）。
✗
He have nothing to do with the accident.
✓
He has nothing to do with the accident.
主語為第三人稱單數時，動詞用 has 而非 have。
✗
I have nothing to do with now.
✓
I have nothing to do now. / This has nothing to do with me.
have nothing to do（無事可做）與 have nothing to do with…（與…無關）意思不同；前者不接 with，後者必接 with + 目標對象。
