谁是你的代理人？ 中译英

Who‘s your substitute？

substitute 代理人。
代课教师就是这个词。

英语解释：
If you substitute one thing for another, or if one thing substitutes for another, it takes the place or performs the function of the other thing.

例句：
They were substituting violence for dialogue...
You could always substitute a low-fat soft cheese...
Would phone conversations substitute for cosy chats over lunch or in the pub after work?...
He was substituting for the injured William Wales.

注意看最后一句，就是你要的这个意思~

另外，deputy是不对的。A deputy is the second most important person in an organization such as a business or government department. Someone's deputy often acts on their behalf when they are not there.

See？意思是the second most important person第二重要的人

用 这个单词

substitute 代替者

以前代课老师也用这个单词

deputy n.代理人，代表

我平时都用的这个

Deputy
代理人：被任命或授权代表他人行动的人
