mend

Compared meaning: to repair something broken (verb).

比较义项：修理，使损坏的东西恢复正常（动词）。

• fix

  The most common, informal everyday word for repairing something broken; it applies to almost anything, from furniture to gadgets, and sounds casual and general.

  fix是最常见、最口语化的日常用词，几乎可以用来修理任何损坏的东西，从家具到小工具都行，听起来随意、通用。

  Could you fix the leaky faucet in the kitchen?

  你能把厨房里漏水的水龙头修一下吗？

• repair

  More formal than fix, often implying skilled or professional work on machines, vehicles, or structures; it can also be used as a noun, as in 'a repair.'

  repair比fix更正式，常暗示由专业人员对机器、车辆或建筑物进行技术性维修；它也可以作名词使用，如“a repair”（一次维修）。

  The garage will repair your car's engine by Friday.

  修车厂将在星期五之前修好你车子的引擎。

• mend 本词

  Often used for smaller-scale repairs, and can be used intransitively for something healing by itself, as with a broken bone; it sounds slightly old-fashioned compared to fix.

  mend常用于规模较小的修补，也可以不及物地表示伤口、骨折等自行愈合；相比fix，它的语气略显旧式。

  The doctor said the broken bone would mend within six weeks.

  医生说这处骨折需要六周才能愈合。

Fix, repair, and mend all mean to make something broken work again. Fix is the most common, everyday word, used for almost anything. Repair is more formal, for machines or vehicles. Mend suits smaller items, and can also mean healing naturally, like a broken bone.

这三个词在“修理”这个意思上很接近，但语气和适用范围不同：fix最口语化、最常用，几乎什么东西都能fix；repair更正式，多用于机器、车辆等专业维修场合；mend则偏向小物件的修补，也常表示伤口、骨折等自然愈合，语气略旧。这里不比较fix的“确定、安排（时间）”等其他义项，也不比较mend在“mend fences”一类习语中“改善关系”的引申义。

Compared meaning: fixing something broken, or the fixed spot (noun).

比较义项：修理、修补（名词，指修复破损物品的行为或修补处）。

• repair

  A general, fairly formal word for the act of fixing something broken, especially machines, vehicles or buildings; often follows phrases like 'in need of' or 'beyond'.

  一个较为正式的通用词，指修理破损物品（尤指机器、车辆或建筑）的行为，常出现在「需要修理」或「无法修理」这类说法中。

  The garage estimated the repair would cost around two hundred dollars.

  汽车修理厂估计这次修理大约需要花费两百美元。

• mend 本词

  A less common, more informal or old-fashioned word for a repaired spot, usually on clothing or small household items, made by sewing or patching.

  一个不太常用、较为口语化或略显过时的词，指衣物或小件物品上经缝补或打补丁而修复的地方。

  Her grandmother's mend on the sleeve was so neat you could hardly spot it.

  她奶奶在袖子上打的补丁缝得非常整齐，几乎看不出来。

Repair and mend can both mean fixing something broken. Repair is general and fairly formal, often for machines, vehicles, or buildings. Mend is less common, informal, naming a sewn, patched spot on clothes. Verb uses, such as mend for healing wounds, are not compared.

这两个词都可表示“修复破损物品”，但repair更正式、更通用，常指机器、车辆或建筑等较大物品的修理工作；mend较为少见，语气更随意，通常指衣物或小物件上经缝补而留下的修补痕迹或补丁。这里不比较mend作动词表示伤口、骨折等“愈合”的用法，也不比较repair作动词“修理”的用法。
