[求助]两道PP structure

82. As the centrally control organ of the body, the brain governs the functioning of the body's other organs.

B错。centrally是不是应改成centralized? 如果不改就一定错么？毕竟centrally也是个副词，可修饰control啊！

反之，functioning的ing不是很多余么？直接用function不就可以了么？

130. Intricate choreographer emphasized the beauty and virtuosity of the nineteenth-century prima ballerina, while the male dancer functioned only as her partner until the twentieth century.

A错。choreographer有什么错？

去下个CD刚刚隆重推出的《PP语法笔记》吧！有详细的解释。
