TN 15 一道语法题

billkp

New genetic evidence-together with recent studies of elephants' skeletons, tusks, and other anatomical features-provide compelling support for classifying Africa's forest elephants and its savanna elephants as separate species.

• Aprovide compelling support for classifying
• Bprovide compelling support for the classification of
• Cprovides compelling support to the classification of
• Dprovides compelling support for classifying
• Eprovides compelling support to classify
  

DE之间搞不清啊……   答案是D，但是E to do 做状语不行么……  而且记得曼哈顿上说过 to do 的逻辑主语和句子主语是可以不对等的。

比如：The weight was lifted to free my leg      weight 显然不是 to do 的逻辑主语，但是这句话还是对的。曼哈顿上的

provide A for B  是 idiom

OG 13 的 第18题 正确选项里就有 create a ... to take charge of .  解释中说 to 有 in order to 的含义。

这里动词是provide，provide sth for的结构，OG上有道题目也是如此，仅有的for doing 击败 to do

EXAMPLE 1


New genetic evidence - together with recent studies of elephants’ skeletons, tusks, and other anatomical features - provide compelling support for classifying Africa’s forest elephants and its savanna elephants as separate species.

A. provide compelling support for classifying
B. provide compelling support for the classification of
C. provides compelling support to the classification of
D. provides compelling support for classifying
E. provides compelling support to classify

MEANING ANALYSIS:

The sentence says that New genetic evidence together with some other things provide compelling support. Support for what? Support for classifying Africa’s forest elephants and savanna elephants as separate species.

PoE:

Again, the error analysis helps us eliminate the first three choices for errors we are not discussing here. Again the only difference between D and E is “for classifying” and “to classify”.

D. provides compelling support for classifying: Per the meaning, new genetic evidence provides support. Most certainly, the new genetic evidence does not have any purpose for providing such support. Rather we can ask what is this support for? This support is for doing something else. Hence this choice correctly uses “for classifying”.
E. provides compelling support to classify: This choice is clearly incorrect because there cannot be any purpose here per the context of this sentence.

P.S: Also, this sentence involves usage of correct idiom. “provide support or help” is always followed a preposition + Noun. Hence, choice E is incorrect idiomatically as well.

谢谢了，还是从动机上理解吧，evidence 没有动机去clarify， 它只能是为某观点提供支持。
