og 239

og 239. Organized in 1966 by the Fish and Wildlife Service, the Breeding Bird Survey uses annual roadside counts along established routes for monitoring of population changes of as many as, or of more than 250 bird species, including 180 songbirds.

(A) for monitoring of population changes of as many as, or of

(B) to monitor population changes of as many, or

(C) to monitor changes in the populations of

(D) that monitors population changes of

(E) that monitors changes in populations of as many as, or

C is the best choice.  

og解释：population changes in B is less precise than changes in population. Why？

原文中是 as many as, or more than ，虽然OG解释说这种用法wordy，答案C选项的确很简洁，但感觉比原文的意思少了什么

谁能帮我解释一下？

我覺得changes in the populations of more than 250 bird species和population changes of more than 250 bird species，兩者的意思是不一樣的。changes in the populations of more than 250 bird species：250多種鳥數量的變化；population changes of more than 250 bird species：population好像是脩飾changes的，感覺population changes成暸一個專用的名詞。

先不攷慮原文的意思，單從語法角度來看，ABDE都有錯誤，排除，不能總是把A默認為正確的意思。既然正確答案的意思是more than，那么as many as, or more than的說法自然是wordy嘍^_^

谢谢楼上JJ咯

我经常犯这种错误呢，老是在改变原文含义的选项和不明显的语法错误之间挣扎。。。。。。

看来还没练出火眼金睛，需要继续努力。。。。。。。：

population changes of more than 250 bird species：如果population有形容词作用，那么of more than 250 bird species就成了修饰中心词changes，但逻辑上应该修饰population。

peajack:

more than是大于等于的意思，as many as是它的子集，确实没有少什么。

另外一個相關的。請特別注意括號內的解釋。

161. A wildlife expert predicts that the reintroduction of the caribou into northern Minnesota would tail if the density of the timber wolf population in that region is more numerous than one wolf for every 39 square miles.

(A)  would fail if the density of the timber wolf population in that region is more numerous than

(B)  would fail provided the density of the timber wolf population in that region is more than

(C)  should fail if the timber wolf density in that region was greater than

(D)  will fail if the density of the timber wolf population in that region is greater than

(E)   will fail if the timber wolf density in that region were more numerous than

D, the best choice, uses a correct sequence of present and future indicative verb forms--predicts, will fail, and is--in the three related clauses. Density, an abstract "mass" noun, is logically construed with greater than. In A and B, would fail disagrees with the other verbs in tense and mood. Choice A misconstrues density with more numerous than, and B uses the pretentious and illogical word provided for ifm a conditional clause after a negative idea (would fail). C's should fail and was are confusing and inconsistent with predicts. C and E use the absurd phrase timber wolf density. (The wolves are not dense; their population is dense.) E also uses an inconsistent subjunctive form, were, and misconstrues density with more numerous than.

所以此类问题应该从修饰准确性的角度考虑，才能从根本上解释为何“名词修饰名词不优选”。
