用法筆記

Typically used predicatively — after a linking verb like 'be', 'remain', 'lie', 'fall', or with a verb like 'find' or 'knock'. Attributive use ('an unconscious patient') is possible in medical writing but less common in everyday English.

常見錯誤

文法句型

unconscious + noun (thought, feeling, habit, bias, gesture)

用法筆記

Used attributively before nouns that describe mental events or physical actions. Distinguish from sense 1 (NOT AWAKE) — sense 1 describes a medical state of being physically unresponsive; sense 2 describes everyday mental processes that happen without your awareness.

常見錯誤

    stronger; suggests complete lack of attention

  • ignorant

    negative connotation; lacking knowledge

  • heedless

    formal; suggests careless disregard

反義詞

文法句型

unconscious of + noun/gerund/clause

用法筆記

Always followed by 'of' + noun, gerund, or a clause. Distinguish from sense 2 (NOT DELIBERATE) — sense 3 describes a lack of awareness about external facts or situations, not internal mental processes. Common in formal writing; 'not aware' is more natural in everyday conversation.

常見錯誤

❌He was unconscious to the warning signs.
✅He was unconscious of the warning signs.
💡'unconscious' takes the preposition 'of', not 'to.'
❌She was unconscious about her mistake.
✅She was unconscious of her mistake.
💡Use 'of' after 'unconscious,' not 'about.'
