What are common mistakes with "Reason"?Which "Reason" sentences look correct but are wrong?
×The reason of his absence is illness.

使用 "reason" 時，後面通常接 "for" 來表示原因，而不是 "of"。"reason of" 在現代英語中極少使用，且聽起來不自然。
×The reason why he left is because he was tired.
✓The reason (why) he left is that he was tired.
"The reason is because..." 是冗餘且不正式的用法，因為 "reason" 和 "because" 都表示原因。標準用法是 "The reason is that..."。"why" 在從句中是可選的。
×I reasoned him to change his mind.
✓I reasoned with him to change his mind.
動詞 "reason" 表示「說理、推論」時，若對象是人，需使用介系詞 "with"，形成 "reason with someone" 的片語，意為「與某人說理、勸說」。
×He reasoned that the plan was too risky.
✓He reasoned that the plan was too risky.
動詞 "reason" 的過去式與過去分詞是規則變化，直接加 "-ed"。不規則變化 "roason" 或 "rosen" 是錯誤的。
×I can't see any reason of doing this.
✓I can't see any reason for doing this. / I can't see any reason to do this.
表達「做某事的理由」時，常用 "reason for + V-ing / noun" 或 "reason to + verb" 的結構。"reason of doing" 是錯誤的搭配。
×By what reason did you arrive late?
✓For what reason did you arrive late? / Why did you arrive late?
詢問原因時，正式說法是 "For what reason...?"，而 "By what reason...?" 是不正確的。口語中更常用 "Why...?"。
