比较义项：使缩小、变小（动词）。

• contract

  Formal, technical register; used for gradual or measurable size decrease, e.g. metal, muscles, pupils, gases in science or medical contexts.

  语域正式、偏技术性；用于描述渐进或可测量的体积缩小，例如金属、肌肉、瞳孔、气体等科学或医学语境。

  Metal pipes contract slightly in cold weather and expand again in heat.

  金属管道在寒冷天气中会略微收缩，遇热后又会膨胀。

• shrink 本词

  Everyday, informal word; commonly used for fabric or clothing losing size after washing or heat, also figuratively for amounts or budgets.

  日常口语常用词；常用于衣物或布料经清洗或受热后缩水，也可比喻用于数量或预算的减少。

  The wool sweater began to shrink after the first wash.

  这件羊毛衫第一次洗涤后就开始缩水。

Contract and shrink both mean to become smaller. Contract is formal and technical, used for a gradual, measurable decrease, like metal, muscles, or gases in science or medicine. Shrink is everyday and informal, often used for clothes losing size after washing, or amounts decreasing.

这两个词都可以表示物体变小，但语域和搭配不同：contract 是较正式、书面化的用词，常见于科学、医学或技术语境；shrink 是日常口语常用词，尤其常与衣物、布料遇水或加热后缩水连用。这里不比较 contract 的“签订（合同）”这一常见义项。

Compared meaning: to draw back from fear, pain, or embarrassment (verb).

比较义项：因恐惧、疼痛或尴尬而退缩、畏缩（动词）。

• shrink 本词

  Shrink emphasizes avoiding or drawing back from something out of fear, often used with 'from' plus a noun or gerund, suggesting reluctance rather than a quick physical reflex.

  shrink 强调因害怕而回避、退缩，常与“from + 名词/动名词”连用，表示不情愿去面对某事，而不是瞬间的生理反射动作。

  一想到要在这么多人面前讲话，她就退缩了。

• wince

  Wince describes a brief facial grimace or slight bodily reaction caused by sudden physical pain, focusing on the visible expression rather than a large movement away.

  wince 指因突然的疼痛而做出短暂的面部表情或轻微的身体反应，重点在于那种可见的表情，而不是大幅度地后退。

  She winced when the dentist touched her sensitive tooth.

  牙医碰到她敏感的牙齿时，她疼得皱了皱眉。

• flinch

  Flinch highlights an instinctive, often small physical movement away from an expected blow, pain, or threat; it is commonly used to describe courage when someone 'doesn't flinch'.

  flinch 强调面对预期的打击、疼痛或威胁时本能的、通常很小的身体后退动作，常用“didn't flinch”来表示某人毫不畏惧、很有勇气。

  He didn't flinch when the balloon suddenly popped next to his ear.

  气球突然在他耳边炸开，他却毫不退缩。

• cringe

  Cringe focuses on the uncomfortable, often lingering feeling of embarrassment, for oneself or someone else, and does not necessarily involve any physical movement or actual pain.

  cringe 强调因尴尬（可能是替自己或替别人感到尴尬）而产生的不舒服、常常持续更久的感觉，不一定伴有实际的身体动作，也和真正的疼痛无关。

  每次想起我在会议上讲的那个笑话，我都觉得尴尬。

Shrink, wince, flinch, and cringe mean to draw back from fear, pain, or embarrassment. Shrink means to avoid something from fear. Wince is a quick reaction to sudden pain. Flinch is a small, instinctive move away from a threat. Cringe is the feeling of embarrassment.

这几个词都表示因恐惧、疼痛或尴尬而身体或情绪上有所退缩，但侧重点不同：wince 和 flinch 强调瞬间的生理反应，cringe 偏重尴尬带来的不适感，shrink 则强调因害怕而回避、退缩不前。这里不比较 shrink 表示“（衣物等）缩水、变小”的常见义项。
