Expiration

“Expiration”是名词,有两种主要含义:1. 呼气的行为;呼出。2. 某事的结束或终止;当某物到期或失效时。

  1. “The expiration of the lease is next month.” (租约下个月到期。)
  2. “She held the breath of anticipation until expiration.” (她屏住期待的呼吸直到呼气。)
  3. “Check the expiration date on the milk before buying it.” (购买前检查牛奶的到期日期。)

“Expiration”来自拉丁语”expirationem”,来自”expirare”(“ex-”(“出”)+ “spirare”(“呼吸”))。

“Expiration”由前缀”ex-”(出)+ 词根”spir-”(呼吸)+ 后缀”-ation”(名词,表示行为)构成。

“Expiration”在1530年左右首次使用。这个词常用于描述合同、许可证、食品等的到期时间。

  • 动词形式: “expire”(到期、呼气)
  • 形容词形式: “expired”(已到期的)

“Expiration”的音标是/ˌɛk-spə-ˈreɪ-ʃən/,可以联想”ex-”(出)+ “spire”(呼吸)+ “-ation”(行为),想象呼出的行为。

“The expiration date on the medicine bottle was clearly marked. After expiration, the medication would lose its effectiveness and could potentially be harmful.” (药瓶上的到期日期清楚地标记着。到期后,药物会失去效力,并可能有害。)
