用法說明
How is "Professional" different from similar structures?What usage mistakes are common with "Professional"?
professional as vs professional to be
- professional as + 名詞 強調「以...的身份是專業的」，通常指在特定角色或職位上的專業性。
- professional to + 動詞 則較為少見且不自然，通常用於表達「為了...而專業」或「專業到足以...」，但更常見的用法是 professional enough to + 動詞。
- 在描述某人的行為或態度時，It is professional of someone to + 動詞 是一個常用結構，用於評價某個具體行為是否專業。
- 直接修飾名詞時，professional 通常置於名詞前，如
professional advice（專業建議）。 EN: She is professional as a project manager. 翻譯: 她作為專案經理非常專業。
EN:It was professional of him to handle the complaint so calmly.
翻譯:他如此冷靜地處理投訴，顯得很專業。
總結建議
在大多數情況下，使用「professional as + 角色」來描述人在特定身份下的專業性，或用「It is professional of someone to...」來評價具體行為，避免使用「professional to + 動詞原形」的結構。

常見錯誤
What are common mistakes with "Professional"?Which "Professional" sentences look correct but are wrong?
×He is a professional.
✓He is a professional.
This is not a mistake. The confusion arises because learners often think 'professional' cannot be a noun. It can be both an adjective and a noun. The mistake is in thinking the noun usage is wrong.
×His behavior was very professional.
✓His behavior was very unprofessional.
Learners sometimes use 'professional' to describe negative conduct, but 'professional' is positive. The correct word for negative conduct is 'unprofessional'.
×He studies at a professional school.
✓He studies at a vocational school.
In English, 'professional' often relates to white-collar jobs requiring advanced education (e.g., lawyer, doctor). Schools for skilled trades (e.g., plumbing, carpentry) are usually called 'vocational schools' or 'trade schools'.
×She works very professional.
✓She works very professionally.
'Professional' is an adjective. To modify a verb like 'works', the adverb form 'professionally' must be used.
×His professional job is very demanding.
✓His job is very demanding.
Using 'professional' directly before 'job' is often redundant, as a 'job' is typically professional by nature. It's more natural to just say 'job' or use 'professional' to describe the person or their conduct.
×He plays piano in a professional level.
✓He plays piano at a professional level.
The correct preposition to use with 'level' in this context is 'at', not 'in'.
