I have grown up!
I'm a grown up already!
用have ...或者 already,都可以强调“已经”.我已经不是一个小男孩了 怎么说I'm not a little boy any more.I anymore is a little boy 对不对不对。如果要放前面可以用no longer：I'm no longer a little boy.anymore 只能放后面？any more和any longer肯定要放在not后面。如果是no，则可以代替not的意思，出现在前面。这些表达的意思都差不多：I'm not a little boy any longer.I was a little boy, but not any more.I used to be a little boy, but no longer.I'm no longer a little boy.
