？？/126.             Cooperative apartment houses have the peculiar distinction of being dwellings that must also operate as businesses.

(A) of being dwellings that must also operate as businesses

(B) of dwellings that must also operate like business

(C) that they are dwellings that must operate like business

(D) that, as dwellings, they must also operate like businesses（A）

(E) to be a dwelling that must also operate as a business

being 不是不对的嘛？如果b中的business为复数是不是b比较好

rt316

being不是错误的标志，虽然很多being都错；B中的致命错误在于like的用法错了。

建议MM先将OG看3遍再做大全，或许会更有收获。
