As it is with traditional pharmacies, on-line drugstores rely on prescriptions to be successful, since it is primarily prescriptions that attract the customers, who then also buy other health-related items. (A) As it is with traditional pharmacies, on-line drugstores rely on prescriptions to be successful (A中,it指代不是很清楚,即使如果是向后指drugstores,那么也是用复数才对) (B) As with the case of traditional pharmacies, on-line drugstores rely on prescriptions to have success (to have success用法很别扭,而且这个选项让未划线部分的sine it is中的it没有了指代) (C) As is the case with traditional pharmacies, prescriptions are the cornerstone of a successful on-line drugstore (D) As traditional pharmacies, so on-line drugstores rely on prescriptions to be successful (句子少主语) (E) Like traditional pharmacies, the cornerstone of a successful on-line drugstore is prescriptions (前后比较对象不一致) C中,as is the case with traditional pharmacies看起来很奇怪,其实是一个主谓倒装结构,其实就相当于是as the case is with traditional pharmacies, prescriptions are the .....没划线部分的since it is中it指a successful on-line drugstore.
