having been done 的问题

默默楚 · 发表于 2013-3-9 16:51:55

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 havingbeen taken off a drug too soon.
这里having been prescribes ... 是做伴随状语么？还是非限定性定语修饰 treatment.
谢谢

没有having 去修饰treatment 的情况的。退一步说即使有 treatment 不会被开药。逻辑也不通。

这个句子有毛病吧我觉得，应该是having, for example, been prescribed a drug at a dosage too low to be effective or havingbeen taken off a drug too soon，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 havingbeen taken off a drug too soon. 应该是做伴随状语吧，因为逻辑主语应该是 Some patients, 如果做后置定语，就像li3360065 说的，don't make sense 啊
