把 occasion 联想成“场合”，一个特殊场合会引发（引起）一系列事情；动词义就是“引起、导致”。
语域：formal 常见场景：正式写作、学术或法律文本、正式演讲 occasion 作动词时通常用于正式场合，多出现在书面语或正式讲话中，表示“引起、导致”。日常口语中更常用 cause 或 bring about。
真正的同韵词：persuasion、invasion、equation 都与 occasion 押韵，均以 /eɪʒən/ 结尾。注意 decision 和 vision 虽也含 /ʒən/，但重读元音是 /ɪ/，并不押韵。拼写上都带 -sion，但 occasion 中的 -sion 读 /ʒən/，不要读成 /ʃən/。
