用法說明
How is "Stupid" different from similar structures?What usage mistakes are common with "Stupid"?
stupid doing vs stupid to do
- stupid doing 通常用於描述一個已經發生或正在進行的行為，強調該行為本身是愚蠢的。
- stupid to do 則用於評論一個（通常是泛指的）行為或決定，指出「去做某事」是愚蠢的。
- 在 It is/was stupid to... 的句型中，只能用 to do，這是固定結構。
- 在口語中，stupid doing 有時聽起來較不正式，但兩者常可互換，語意差異細微。 EN: It was stupid driving so fast on a wet road. 翻譯: 在濕滑的路面上開那麼快真是愚蠢。
EN:It would be stupid to drive so fast on a wet road.
翻譯:在濕滑的路面上開那麼快會是愚蠢的。
EN:I think his stupid quitting the job without a plan was a mistake.
翻譯:我認為他沒計劃就辭職的愚蠢行為是個錯誤。
EN:It was stupid of him to quit the job without a plan.

常見錯誤
What are common mistakes with "Stupid"?Which "Stupid" sentences look correct but are wrong?
×He is a stupid.
✓He is stupid.
「stupid」是形容詞，不能直接當名詞使用。若要指「一個愚蠢的人」，應使用「a stupid person」或「a fool」。
×This idea is very stupid.
✓This idea is really stupid / incredibly stupid.
雖然文法上「very stupid」可以接受，但在口語中，為加強語氣，更常使用「really」、「incredibly」、「so」或「absolutely」等副詞來修飾「stupid」。
×They are stupids.
✓They are stupid people. / They are fools.
「stupid」作為形容詞沒有複數形式。不能直接加「-s」當成名詞複數。必須使用「stupid people」或換用其他名詞如「fools」。
×This is stupider than that.
✓This is more stupid than that. / This is stupider than that.
「stupider」和「more stupid」都是正確的比較級形式。但學習者常誤以為「stupider」是錯誤的，或反之，誤以為只能使用「more stupid」。實際上兩者皆可，但「more stupid」在正式寫作中更常見。
×It was stupid for him to say that.
✓It was stupid of him to say that.
在「It is/was + adjective + of + someone + to do」的句型中，當形容詞描述人的特質（如 stupid, kind, clever）時，介系詞應使用「of」，而非「for」。
×He acted stupid.
✓He acted stupidly.
「stupid」是形容詞，修飾動詞「acted」時應使用副詞形式「stupidly」。形容詞用於描述名詞（如 a stupid act），副詞用於描述動作如何進行。
