Announced
常带有官方或公开性质，如公司发布新产品、政府发布政策；语气比随意告诉他人更正式。
- “The mayor announced a new housing plan.” (市长宣布了一项新的住房计划。)
- “Winners were announced at the end of the ceremony.” (典礼尾声公布了获奖者。)
- “The airline announced a delay due to weather.” (航空公司因天气原因宣布延误。)
“announce” 源自古法语 anoncer，来自拉丁语 annuntiare（带来消息），由 ad-（向）与 nuntius（信使）构成。
an-（同 ad-，向）+ nounce（报告）+ -ed 构成过去式与过去分词。
新闻发布会、体育转会窗与科技 keynote 中高频出现；被动 “it was announced” 突出信息来源权威。
- 固定搭配: “announced publicly” (公开宣布), “newly announced” (刚刚宣布的)
nounce 联想 pronounce 的“发声”部分：把消息大声向外界抛出去。
“The school announced a snow day, and cheers echoed through the hallways.” (学校宣布雪天停课，走廊里响起一片欢呼。)
