英文通知的格式通常包括開頭語、正文和結束語。以下是一個英文通知的模板：
開頭語：
Notice is hereby given that...(茲通知)
正文：
(活動詳情)
結束語：
Everybody is expected to attend it. Be sure to attend it on time. Please/Do be present on time.
例如，如果需要通知學生參加一個學校活動，可以這樣寫：
NOTICE
Our school will have a meeting on the playground at 3:00 p.m. on June 18th. The meeting is about being away from net bars and refusing unhealthy publications. We'll visit a picture show about healthy knowledge after the meeting. Please get there on time with your chairs.
Please be present on time. That's all.
以上模板可以根據具體情況進行修改和調整。
