记忆技巧Memory Tip
overrun = over(超过)+ run(跑): 跑过头就是超出量;飞机跑过头需要跑道端安全区;冰淇淋跑过头注入空气,体积膨胀。
语境与语域Context & Register
语域:neutral 常见场景:project status reports、budget audits、construction contracts 该名词义项(超出量、超额)通常用于项目、预算等正式或半正式场合,如 cost overrun(成本超支)、schedule overrun(进度超限),多出现在报告、审计或媒体新闻中;日常口语较少直接用 overrun,更常说 go over budget。
发音与拼写Pronunciation & Spelling
这些单词都与 overrun 的尾音节 /rʌn/ 押韵(重读元音 /ʌ/ + 辅音 /n/)。注意 one 的拼写与发音不一致;overrun 虽然以 run 结尾,但整体读音为 /ˌəʊvəˈrʌn/,请勿与 overdue(/ˌəʊvəˈdjuː/)等词混淆。
