文法句型

ungrateful + noun describing a job, duty, or role

用法筆記

Unlike sense 1, this sense does NOT describe people who lack gratitude. It only modifies tasks, roles, duties, or situations. The closest equivalent is 'thankless' (a thankless task = an ungrateful task). This sense is less common in everyday conversation and more typical in written or formal contexts.

❌My boss is very ungrateful.' (when meaning the boss is unpleasant)
✅My boss gave me an ungrateful task.
💡This sense describes work, not people. Use sense 1 to describe a person who does not show thanks.

❌ 'It was an ungrateful job, but someone had to do it.' (correct sentence, but do not use with personal subjects) — correct for tasks, but never use this sense to describe a person directly.
