OG239

The answer is C.

But,

Do you guys always say that we can not change the origianl meaning of the sentence? "As many as, or more than" does not have the same meaning as "more than" , right?

Need explanation.

从use sth to do sth的结构，可以排除A, D, E.

B的比较形式错误，as many后面少了个as.

我们总不能为了保持句子原意，而去选一个语法上有硬伤的答案吧.

问个问题, 问什么changes in population比population changes好,ETS偏爱这种结构吗?

谢谢!

从语法角度来讲, 形容词修饰名词, 用名词修饰名词不合理. 虽然我在日常生活中看到过这样的例子, 但OG上还没有, 有可能我看得不够细, 若有发现记得告诉我. 所以population changes不规范, changes in population才是正确的表达.

OG里有一题极其相似

OG161. 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 (D)

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

抛开用wolf与density搭配, 而不是density与population搭配这个错误, CE都用了wolf density(名词修饰名词)这个表达, 而ABD用的是the density of the wolf population. 不知楼上有没有领会我的意思. ETS给我们的判断是多方面的, 也就是说错误的选项若与正确选项有出入的地方, 多半(不绝对, 有反例子)那种表达就不好. 所以名词修饰名词不优选.

“辩证”

就是我要表达的核心思想。MM估计阅读主体提没有问题了

又找到一个印证! 这个更好!

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. The phrase to monitor changes is idiomatic as a statement of purpose ([in order] to monitor), and the intended meaning is expressed concisely and accurately. Neither A nor B produces the idiomatic phrase "... as many as, or more than, 250 ..."--a phrase that would be needlessly wordy here. Also, for monitoring of in A is less concise and idiomatic than to monitor, and population changes in B is less precise than changes in population. In D and E, the pronoun that has no singular noun (required by the verb monitors) to which it can logically or grammatically refer. Survey already has its verb in uses, and no other noun can perform the action of monitors.
