她替代我用英语

根据我的理解，你是一个老师，要对你的学生们说下趟课由别人来替我，如果是这个意思的话：1）选用一个核心的关键单词 act结构：act for sb/act on sb's behalf意思：to represent someone, especially in a court of law or by doing business for them（代表某人，尤其是为他们在法庭或工作中做某事） 例1，Makin, a solicitor, is acting for the young people in their case against the county council.（事务律师Makin,代表那个年青人反对乡村选举的案件） 例2，I am acting on behalf of the bank.（我做银行的代言人）2）你的单句翻译：He is acting for me on your next calsses.(他替我给你们上课）3)你需要的情景翻译：你对你的学生们说：Hi guys, I will leave for some classes. During my absence,he will act for me on the coming classes. I hope you all have a good time with him. Keep up every day!希望对你有用。
