54. 

(A) Unlike using spices for cooking, in medicinal usage they are taken

(B) Unlike spices that are used in cooking, in using spices for medicine, they are taken

(C) Unlike cooking with spices, taking spices for medicinal use is done

(D) In cooking, small quantities of spices are used, whereas in medicinal usage spices are taken

(E) In cooking, the usage of spices is in small quantities, whereas in medicinal usage they are taken

答案为D, C出错在哪里？请指教，谢谢！

顶一下，我也想知道这道题目的解释。

C有什么明显的错误吗？

D 是正确答案，要维持平衡，small quantity 和large quantity出现的位置前后不一致都不要紧吗？

D是 In cooking, small quantities of ...are used, whereas in mecicinal usage (介词短语对仗得很好)spices are taken(语态也很对仗) in large quantities............

最好是不是应该写成： In cooking, spices are used in small quantities, whereas in mecicinal usage...............................

虽然D不是最佳的表达方法，但也属于可以的？
