"At"和"with"不是同類詞，它們在語法和用法上有很大的區別。
"At"通常用於表示時間、地點、事件等，例如：
I will meet you at the park at 3 pm.
She is studying at the library.
He was surprised at the news.
"With"通常用於表示陪伴、伴隨、具備等，例如：
I went to the party with my friends.
She is wearing a dress with flowers on it.
He is a man with a lot of experience.
因此，雖然"At"和"With"都是介詞，但它們的用法和意義不同，不能互換使用。
希望對您有幫助！
