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!
