talk about sth，sth可以是人吗？

如题，谈论关于。。。，后面可以接认吗？比如，可不可以说 talk about her classmates？谈论她的同学？

Yes, you can.
e.g. talk about yourself! talk about her mother.
如果你是想别人告诉你sth..
You can say "Tell me about your classmate!"

可以，talke about sth./sb.都可以。 比如：接物，Let's talk about this question.(让我们来讨论一下这个问题。) 接人，像你说的那个例子，talke about her classmate.

alk about sth 谈论某事 we all have goals and dreams – whether or not we ever talk about them，即使我们并没有说出来或者写下来, or write them down. 我们都是有目标和梦想的
