哎，看到那么多不确定题，我真是无语了

有时候答案给 to do 有时候给for doing 我 觉得很无语，没有统一的解释，理解了又被推翻 GWD 真累啊

这几个题从逻辑意思入手可能会更好解决一点

GWD-18-Q19
            

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

provide的主语是evidence，E选项有evidence提供support为了classify的意思，逻辑意思显然出了了问题

如果要选E的话要改成  provides compelling support for us to classify

1. GWD28-Q1:

Scientists claim that the discovery of the first authenticated mammal bones in amber could provide important clues of determining, in addition to how, when mammals colonized the islands of the West Indies.

 

A.      of determining, in addition to how, when mammals colonized the islands of the West Indies

B.      in the determination of how and when the islands of the West Indies were colonized by mammals

C.      to determine how mammals colonized the islands of the West Indies and when they did

D.      for determining when the islands of the West Indies were colonized by mammals and how they were

E.       for determining how and when mammals colonized the islands of the West Indies

这题也同样，provide的发出者是amber而不是scientist，amber提供clue只是能determine而不是为了determine

C改成  for scientists
                        to determine how mammals colonized the islands of the West Indies and when they did so 就没问题了，但还是没E简洁

楼上的感觉有点道理，不过可以再稍微总结一下这个区别吗？感觉还有有点模糊

以下是引用ll_zl在2008-4-26 17:29:00的发言：
应该选E，这种题有些很隐秘规律
原文clues of determining的结构,看出ETS是想表达determine是用来修饰clue的，做clue的定语，而不是用来表目的的。所以C中的to结构可以看做是修改原文的意思，应该舍弃。
但查询了朗文，clue后一般跟的是 clue to/ as to /about + sth. 的结构，所以又怀疑应该是C，但考虑到如果是clue to sth.结构，to 后一定要跟的是名词，则determine一定要用动名词结构，而不能用动词结构。所以C的错误比较明显。
还有下面这个题也有类似现象。C和D争论很大，到现在也没有具体定论。选C的原因是因为to rate表示目的很清晰，天文学家发展了一种刻度是为了定级...。
但我觉得原文给出了暗示，a scale reates the likihood...，说明原文的意思是scale 和 liklihood之间是个主谓关系，因此不是C中的表目的结构。而D中for rating是用来修饰scale，补充说明scale的作用，更符合原文的意思。
17. GWD-26-Q17



Responding to the public’s fascination with-and sometimes
 undue alarm over-possible threats from asteroids, a scale
  developed by astronomers rates the likelihood that a particular asteroid or comet may collide with Earth.



A.      a scale developed by astronomers rates the likelihood
 that a particular asteroid or comet may



B.       a scale that astronomers have developed rates how
 likely it is for a particular asteroid or comet to



C.      astronomers have developed a scale to rate how likely
 a particular asteroid or comet will be to
D.      astronomers have developed a scale for rating the
 likelihood that a particular asteroid or comet will
E.       astronomers have developed a scale that rates the
 likelihood of a particular asteroid or comet that may



但目前还未找到其他的题，因此只能先借这两个题做个小结，希望大家多讨论.

赞同。给出另一类似题。DE之间有争议，答案为D。此题更为单纯，所以对provide sth for doing的讨论更为成熟。一般认为for doing单纯表目的，是对前面名词的补充说明。而to do会有逻辑主语的问题。

iser說的很對，算是此類題的總結。其實也是很有規律的。頂。

忘记在哪里看到的 to do 表目的时其主语必须是动作的发出者
bones不能determine
所以要用for

akiluk

To do 有目的性 而New genetic evidence是物体所以没有目的
