以下是引用mbz在2007-2-9 13:31:00的发言:The answer should be C. D is wrong because you can only charge the price, but not charge something. 不太同意MBZ的观点 Q4: A new hair-growing drug is being sold for three times the price, per milligram, as the drug’s maker charges for another product with the same active ingredient. - as
- than
- that
- of what
- at which
同楼上所述,charge for sth with sth.应该是没有错的,否则就不会被出题者放在后面没划线处. 这里讨论的是as的用法是否正确. 显然用在这里不对:把句子中间的per milligram盖住,也就是说这种新的增发药被以含有同样活性物质的药物的三倍价钱所出售. what指代后者的价钱. ** is being sold for three times the price of what ***我觉得满好~ 个人意见,有问题还请高手指正~ |
