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
實在不懂這題要從何下手...
已經看過PP-SC的詳解了...
詳解上所說的D和E的解釋不是很懂...
<詳解>
(D) 時態上不對稱，現在完成時與過去時並列have been prescribed...
or were taken off...；沒有表達原文的意思，因為when...引導的是時間狀語從句，
但原文的意思（尤其是用了for example）是列舉了兩種inadequate treatment的情況
（用了動名詞形式），而不是在什麼情況下會receive inadequate treatment。
(E) 時態上不對稱，與D選項相同；have在本句是實意動詞，不能充當or後面需要
的助動詞have。
麻煩高手們幫我解惑下這題~謝謝!

1F：推 abase0001:(D)中的連接詞"or"兩邊的時態不對稱,再加上for example 10/13 17:20
2F：→ abase0001:後接的不是例子,而是when..,用來表達跟主要子句的時間 10/13 17:22
3F：→ abase0001:關係,不是在舉例了,所以是錯誤選項 10/13 17:23
4F：→ abase0001:(E)錯的更離譜了,原句是for example, v1... or v2... 10/13 17:24
5F：→ abase0001:(E)卻把對稱的v1,v2改成只剩v1,v2跑去修飾dosage 10/13 17:25
6F：→ abase0001:所以錯。 10/13 17:26
7F：→ abase0001:本題找要是考時態與對稱,還有have做動詞時寫成having 10/13 17:26
8F：→ abase0001:這種東西看到就可以直接刪掉,除非出現在完成式時態才ok 10/13 17:28
9F：→ abase0001:我自己解這題過程是這樣的,看到having,刪ABC,D中的時態 10/13 17:36
10F：→ abase0001:不對稱,刪,E是for example, when..刪,選項都刪光了 10/13 17:36
11F：→ abase0001:再回頭看有沒有having是出現在完成式被我刪掉了,有,A 10/13 17:37
12F：→ abase0001:檢查A後面的時態是否對稱,ok,所以答案選A 10/13 17:37
13F：→ prettyting:感謝a大~理解啦!! 10/13 23:46
