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
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!

1F：推 abase0001:(D)中的连接词"or"两边的时态不对称,再加上for example 10/13 17:20
2F：→ abase0001:後接的不是例子,而是when..,用来表达跟主要子句的时间 10/13 17:22
3F：→ abase0001:关系,不是在举例了,所以是错误选项 10/13 17:23
4F：→ abase0001:(E)错的更离谱了,原句是for example, v1... or v2... 10/13 17:24
5F：→ abase0001:(E)却把对称的v1,v2改成只剩v1,v2跑去修饰dosage 10/13 17:25
6F：→ abase0001:所以错。 10/13 17:26
7F：→ abase0001:本题找要是考时态与对称,还有have做动词时写成having 10/13 17:26
8F：→ abase0001:这种东西看到就可以直接删掉,除非出现在完成式时态才ok 10/13 17:28
9F：→ abase0001:我自己解这题过程是这样的,看到having,删ABC,D中的时态 10/13 17:36
10F：→ abase0001:不对称,删,E是for example, when..删,选项都删光了 10/13 17:36
11F：→ abase0001:再回头看有没有having是出现在完成式被我删掉了,有,A 10/13 17:37
12F：→ abase0001:检查A後面的时态是否对称,ok,所以答案选A 10/13 17:37
13F：→ prettyting:感谢a大~理解啦!! 10/13 23:46
