※ 引述《prettyting (get a food in the door)》之铭言： : Some patients who do not respond to therapies for depression may simply : have received inadequate treatment, having, for example, been prescribed a drug : ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ : at a dosage too low to be effective or having been taken off a drug too soon. : ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ : (A) having, for example, been prescribed a drug at a dosage too low to be : effective or having been : (B) having, for example, a drug prescription that was ineffective because : the dosage was too low, or being : (C) as, for example, having too low of a dosage of a prescribed drug for it to : be effective, or being : (D) when they have, for example, been prescribed too low a drug dosage : to be effective, or were : (E) for example, when they have a drug prescription with a dosage : 答案是A 我的想法是这样的 不知是否有误 欢迎补充以及讨论 A. 正确 for example为插入句,句子可看成 Some patients..have recieved.., having been prescribed..or having been.. having句子修饰some patient的第一层动作"得到不当的treatment" or having been平行结构正确 B. drug prescription不如动词prescribed 但最主要错误在or being....(不平行於having been) C. as, for example 为两个重复性质的词 as作"正如"解, for example又是举例 且如果as作时间连词,後面也应该有主＋动词 还有时态不一致错误 D.E. 改变原句意,原句的having been....是要修饰第一层动词状态的have recieved 也可从时态不一致来删除选项 D的when句子本身就存在时态不一致问题 when they have.....,or were.... E:主句动词时态是现完式,when句子却是现在式(have在此为动词"有") : 实在不懂这题要从何下手... : 已经看过PP-SC的详解了... : 详解上所说的D和E的解释不是很懂... : <详解> : (D) 时态上不对称，现在完成时与过去时并列have been prescribed... : or were taken off...；没有表达原文的意思，因为when...引导的是时间状语从句， : 但原文的意思（尤其是用了for example）是列举了两种inadequate treatment的情况 : （用了动名词形式），而不是在什麽情况下会receive inadequate treatment。 : (E) 时态上不对称，与D选项相同；have在本句是实意动词，不能充当or後面需要 : 的助动词have。 : 麻烦高手们帮我解惑下这题~谢谢! --
