mind

Compared meaning: the mind, the ability to think and feel (noun).

比较义项：头脑、心智（思考、感受和记忆的能力）（名词）。

• mind 本词

  Neutral, all-purpose word for the seat of thought and consciousness; works in both everyday and formal writing, without the informality of head or the organ-linked imagery of brain.

  语域中性、最通用的词，指思考和意识的所在；日常和正式场合都可使用，不像 head 那样口语化，也没有 brain 那种器官化的比喻色彩。

  Meditation helps clear my mind before an important exam.

  冥想有助于在重要考试前让我的头脑清醒。

• head

  Informal, everyday word for the mind, common in casual idioms about thinking, worrying, or natural talent; less formal than mind and rarely used in academic writing.

  口语化、日常用词，指头脑，常见于关于思考、担心或天赋的习语中；比 mind 更随意，很少用于学术写作。

  He has a good head for numbers and never needs a calculator.

  他很有数字头脑，从不需要计算器。

• brain

  Emphasizes mental processing power or intelligence, often figuratively linked to the physical organ; common in idioms about hard thinking or effort.

  强调思维能力或智力，常带有与身体器官相关的比喻色彩；常见于表示费心思考或努力的习语中。

  I racked my brain all night trying to remember her name.

  我绞尽脑汁想了一整晚，试图想起她的名字。

• psyche

  Formal, often psychological or literary term for a person's deep inner mental and emotional life; used when discussing psychological effects, not casual daily thoughts.

  正式、常用于心理学或文学语境的词，指一个人内心深处的心理和情感世界；用于讨论心理影响，而非日常随意的想法。

  Years of harsh criticism left a lasting scar on his psyche.

  多年严厉的批评给他的心理留下了持久的创伤。

Mind, head, brain, and psyche all mean the mind. Mind is the neutral, general word. Head is informal, common in idioms about thinking or worry. Brain stresses mental power, often linked to the physical organ. Psyche is formal, used in psychology for someone's inner life.

这几个词都能表示头脑或心智，但语域和搭配不同：mind 最通用、语域中性；head 口语化，常见于习语；brain 强调思维能力，带器官化的比喻色彩；psyche 正式，偏心理学或文学语境。这里不比较 mind 的介意（动词）或改变主意等用法；不比较 head 的头部（身体部位）或领导、首脑等用法；不比较 brain 作为脑器官本身（医学意义）的用法。

Compared meaning: to pay careful attention to something (verb).

比较义项：留心、注意（提防危险或听从劝告）（动词）。

• mind 本词

  Informal and everyday; usually an imperative warning about a nearby physical hazard (mind the gap/step), rarely takes advice or an opinion as its object.

  非正式、口语化，通常用祈使句提醒他人注意眼前的实际危险（如mind the gap/step），很少以劝告或意见作宾语。

  Mind the gap between the train and the platform when you step off.

  下车时要留意火车和站台之间的空隙。

• heed

  Formal, literary word used mainly with advice, warnings, or counsel as its object (heed the warning); rarely used as a bare imperative about physical hazards.

  正式、书面化的词，主要与劝告、警告或忠告搭配作宾语（如heed the warning），很少用作祈使句来提醒身边的实际危险。

  Few teenagers heed warnings about the dangers of texting while driving.

  很少有青少年会听从关于开车发短信危险的警告。

Mind and heed both mean to pay careful attention, to avoid danger or follow advice. Mind is informal, a warning about nearby danger, as in 'mind the gap'. Heed is literary, used with advice or warnings, not physical hazards. Not compared: mind meaning 'object to'.

这两个词在留心、当心这一义项上意思相近，但语域和用法不同：mind口语化，常用于提醒他人注意眼前的实际危险（如台阶、头顶），常用祈使句；heed更正式、书面化，常用于表示听从劝告或警告，日常口语中较少使用，且不用于说明身边的具体危险。这里不比较mind表示介意（如Would you mind opening the window?）或照看（mind the children）等其他常见义项。
