information, announcement, poster, notice.虽然在有些语境里这些单词有相同的翻译，这4 个单词有不同字面意思，通常不可互换。information 主要意思是“信息”，但也有通知，通报，报告，报导，消息，情报，资料，知识，学识，数据 等意思。announcement 公告，通告，布告，宣告，预告，声明，宣布的行动[过程]。poster 1. (贴在墙壁等上的) 广告(画)，海报，标语，招贴。2. 贴标语[广告、传单等] 的人。notice 公告1. （动词，名词）注意；认识。2. （名词）公告，情报，消息；通知，预告，警告；(正式)通告；呈报。4 个单词中 announcement 和 notice （作为名词）的意思最接近。从下面例句你可以看到这些单词的不同意思：Whatever information we need, it is usually available on the the internet.The annoucement that the principal has resigned came as a surprise to many students.A notice was posted on the door annoucing the closure of the school due to the storm.A large poster annoucing the coming concert was put on the window of the concert hall.如果你谷歌 “information sentence" 或 ”notice sentence“， 就会找到例句，通过这些例句你会领悟到这些单词的区别。希望帮到了你，满意敬请采纳，谢谢。
