疑问 GWD一道语法

Spencer125

New geneticevidence—together with recent studies of elephants’ skeletons, tusks, and otheranatomical features—provide compelling support for classifying Africa’s forest elephants and its savanna elephants asseparate species.

E    d

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

答案是D，我选了E。   不懂？   还是这道题是争议题。   新东方总结说  for+ving 当不表示目的时候是可以这么用的。这道题不表示目的，所以D理论上成立，但E又如何排除？

还是to do和 for doing如何区别的问题。
你可以试着这么理解：for classifying，是说分辨两种大象的事情在进行中，而新的基因上的证据为这项工作提供了支持，显然这是一种状态。
to classify，是说工作还没开始，新的证据的提供的支持就是让我们去作分辨两种象的工作，显然是一种目的。

再贴出一个帖子来，你看了也许会有所领悟。
What's the difference between "to do" and "for doing" in a sentence expressing a purpose?

I want to add a bit.

Cherry gave two examples:

"She has to go home to do the housework".
"She has to go home for doing the housework".

These really do not have the same meaning. An English speaker would use the first construction only for this sentence. You will not hear an English speaker say the second. Here is why...

The first will be understood to mean "She has to go home IN ORDER TO DO the housework;" or, "She has to go home BECAUSE SHE NEEDS TO DO the housework." And this is, in fact, what we mean.

The second will be understood to mean "She has to go home AS A CONSEQUENCE FOR DOING the housework;" or, "She DID THE HOUSEWORK, AND SO she had to go home." And this doesn't make sense.

Look at it in another set of examples. Any verb may be substituted for "do":

"to X" (to sleep, to love, to give, etc.)
"for X-ing" (for sleeping, for loving, for giving, etc.)

1. He was sent home early from school TO SLEEP.
2. He was sent home early from school FOR SLEEPING.

The first means the teacher sent the student home IN ORDER TO sleep. He looked tired, and the teachers were merciful. They suggested that he go home FOR THE PURPOSE OF sleep.

In the second, the teacher sent the student home BECAUSE HE SLEPT in class. Going home was a CONSEQUENCE for sleeping when he should have stayed awake.

The only time these are interchangeable is when one of the following is true:

1. The meaning of "in order to" and "as a consequence for" will mean the same thing:

Ex. A: "He was paid $1000 TO BUILD the wall."
Ex. B: "He was paid $1000 FOR BUILDING the wall."

And, even here, be careful. The first (as Cherry pointed out) means he was paid BEFORE the work was done. The second means he was paid AFTER the work was done.

2. The meaning is about the INTENDED PURPOSE or SUGGESTED PURPOSE of an item (or person):

Ex. A: "A hammer can be used TO REMOVE nails."
Ex. B: "A hammer can be used FOR REMOVING nails."

Here, the meanings are quite the same.

没有说哪种理解对不对，而是我阐述了for doing和to do的区别，而题目中显然不是出于目的，所以不能用TO DO.

classifying Africa’s forest elephants and its savanna elephants asseparate species。这种区分一直有，并不是有了新证据后才能得以开始，所以是状态，不是目的。

这道题for doing 是做状语还是定语呢？我发现不定式在GMAT又可以做定语又可以做状语呢。
我好乱乱死了。
