用法說明

happy doing vs happy to do
- happy doing 通常描述對一個正在進行或習慣性的活動感到快樂或滿足。
- happy to do 則強調樂意去做某件事，常指對一個具體的提議、請求或機會的回應。
- 在描述一般性格或狀態時，兩者有時可互換，但 happy doing 更側重「享受過程」，而 happy to do 更側重「願意行動」。
- 在正式提供幫助或回應請求時，通常使用 happy to do（例如：I'd be happy to help.）。 EN: She is happy working from home; she enjoys the flexibility. 翻譯: 她對於在家工作感到快樂，很享受這種彈性。
EN:I would be happy to help you move the furniture this weekend.
翻譯:我很樂意這個週末幫你搬家具。

EN:He texted me, "Just got the news, feeling really happy."

停頓填充
在思考或組織語句時，用來暫時填充對話空檔，語氣通常較為隨意。 EN: So, I was... happy... you know, to finally meet everyone in person. 翻譯: 所以，我當時是…滿開心的…你懂吧，終於能親自見到大家。

正式寫作注意：在學術、商業或正式書面文件中，應避免使用上述口語用法（如引述格式、隨意填充詞或過於誇張的比喻）。建議使用更精確、結構完整的句子來描述情緒狀態，例如 "She expressed her satisfaction with the outcome" 或 "He reported a high level of contentment."

常見錯誤
What are common mistakes with "Happy"?Which "Happy" sentences look correct but are wrong?
×I feel a happy.
✓I feel happy.
"Happy" is an adjective, not a countable noun. Do not use an article (a/an/the) before it when it describes a feeling.
×I am happy for the good news.
✓I am happy about the good news.
Use "happy about" for things or events that cause happiness. "Happy for" is used to express happiness on behalf of another person.
×I am very much happy.
✓I am very happy.
Use "very" directly before the adjective "happy". "Very much" is typically used to modify verbs, not adjectives.
×I am happy that I can help you.
✓I am happy to help you.
While "happy that..." is grammatically correct, "happy to + verb" is a more common and natural pattern for expressing willingness or pleasure in doing something.
×It was a happy moment time.
✓It was a happy moment.
"Happy" is an adjective and modifies a noun directly. Do not add another noun (like "time") that repeats the meaning of the main noun ("moment").
×I have a happy feeling.
✓I feel happy. / I am happy.
While not grammatically wrong, "have a happy feeling" is unnatural. It's more idiomatic to use "feel happy" or "am happy" to describe an emotional state.
