比如像Done as sb have,……的结构可以吗?

没有这种结构
as引导让步状语从句时,用倒装语序,即把作状语的副词或作表语的形容词或名词提前,而且如果作表语的是单数名词,前面不加冠词,也可以把谓语动词部分的实义动词提前.
as可引导让步状语从句,表示“虽然、尽管”,但要用部分倒装结构,形式如下:
1.形容词 + as + 主语 + 系动词.如:
Tired as he is,he offers to help me.
尽管他已经很累了,他还是主动提出帮助我.
2.过去分词 + as + 主语 + 系动词.如:
Well-written as the book is,the author is not satisfied and prepared to revise it.
尽管这本书写得很好,作者还是不满意并打算修改它.
3.名词 + as + 主语 + 系动词.如:
Student as he is,he does not study hard.
他虽然是个学生,却不努力学习.
4.副词 + as + 主语 + 谓语部分.如:
Much as I admire his courage,I don’t think he acted wisely.
我虽然崇拜他的勇气,但我认为他这样做是不明智的.
5.动词原形 + as + 主语 + 谓语的另一部分(情态动词或助动词may,might,will,would等).如:
Try as you will,you won’t be able to persuade him.
不管你怎么努力,你都说服不了他.
