请问下面这句话是什么意思呢？as是"当……时"的意思吗?
60. In the textbook publishing business, the second quarter is historically weak, because revenues are low and marketing expenses are high as companies prepare for the coming school year.
(A) low and marketing expenses are high as companies prepare
(B) low and their marketing expenses are high as they prepare
(C) low with higher marketing expenses in preparation
(D) low, while marketing expenses are higher to prepare
(E) low, while their marketing expenses arehigher in preparation
Parallelism; Logical predication
This sentence is correctly written. It uses parallel structure to give two reasons why textbook publishers have weak second quarters: revenues are low and expenses are high. The construction as companies prepare for the coming school year is clear, as opposed to the awkward constructions using the ambiguous plural pronouns they and their.
A Correct. This sentence uses the parallel forms are low . . . are high and employs the unambiguous companies as the subject of prepare.
BTheir seems illogically to refer to revenues.
The subject oiprepare is the ambiguous they. C Higher is not parallel to low, and it gives no indication of what the comparison is supposed to be (Higher than what?). This construction makes it appear, illogically, that the low revenues have higher marketing expenses.
D Higher is not parallel to low and is illogical. The infinitive construction to prepare ... is awkward.
E Higher is not parallel to low and is illogical since no comparison is being made; their has no clear referent.
The correct answer is A. |
