大全150：搞不懂它的逻辑

gmat700+

At Shiprock, New Mexico, a perennially powerful girls’ high school basketball team has become a path to college for some and a source of pride for a community where the household incomes of 49 percent of them are below the poverty level.

(A) where the household incomes of 49 percent of them are

(B) where they have 49 percent of the household incomes

(C) where 49 percent of the household incomes are

(D) which has 49 percent of the household incomes

(E) in which 49 percent of them have household incomes

C, the best choice, uses a clear, direct, and economical adjective clause to indicate the percentage of household incomes below the poverty line in the community in question. Choices A and E insert the pronoun them without a stated antecedent. In addition, the wording of both A and E confuses the percentage of community residents (the implied referent of them) with the percentage of households, not the same thing at all. Choice B introduces the pronoun they without an antecedent. Furthermore, the use of have in B and E and of has in D illogically suggests that the community possesses 49% of all the household incomes below the poverty line.

这题虽然能选对，但是对句意总是理解不了。看了og解释也不明白，什么叫“家庭收入的49%在贫困线以下”？是单个家庭收入在贫困线以下的家庭占社区所有家庭总数的49%？还是社区所有家庭总收入中的49%来自贫困线以下的家庭？ft，我自己都说得晕了，还是用公式比较好表达：

1、收入水平低于贫困线的家庭的总数 / 社区家庭总数 =  49%

2、所有在贫困线以下的家庭的收入之总和 / 社区所有家庭收入之和= 49%

请大侠们指教，是1还是2？或者都不是？

谢谢石头斑竹！呵呵，这次没叫错吧？

我刚刚看了一下jnlvo的大全简注，jnlvo NN理解的好象2是对的。引用原文如下：

income是一份份的，所以是可数，如果光指钱就应该是不可数。整个区的家庭收入（很多份）的49%处于贫困线下。

还是打个比方吧：

5个家庭的收入(household income)情况：A－$1；B－$2；C－$3；D－$4；E－$5；假设poverty level是$2.5，则below the poverty level的家庭是A and B，则A和B两家的household incomes(用复数) below the poverty level，则40％(AB两家/ABCDE五家) of the household incomes below the poverty level. 所以我理解你的1表达了这个意思，而2则表达收入值，我认为好像不太对。

一份household income应该代表一个家庭。
