请帮我看一下我这句英文说得对吗?谢谢
Could you please confirm whether you will attend ABC's company 20th anniversary tonight?
中文背景:
请问你能确认是否在今天晚上参加ABC公司的20周年庆?

大致没问题,若稍加修饰就更好了!
Could you please confirm(也可用let me know) whether(用if发音更简便) you will attend ABC's company 20th(把th去掉,表示20周年而不是第20次) anniversary( 20 anniversary party/celebration in ABC company) tonight?
