Reptiles, by drawing their body heat directly from the Sun rather
than burning calories to generate it, can survive on ten percent
of the nourishment that a mammal of similar size would normally
require。
A. rather than burning calories to generate it
B.rather than the generation of body heat by burning calories
C.and not from generating it by burning calories
D.instead of by burning calories for generating it
E.instead of body heat generated by burning calories

OA:A
ron的解释是：instead of 后面加名词和动名词，他还说for doing不是正确的idiom.?想问下这里为什么for doing这里不行

找到了另一篇帖子，ron得解释~~！
in general, the modifier “to + verb” is used to signal the goal or purpose of an action/statement, while “for + verbing” conveys the idea that the action is, in some generic way, oriented toward the process of “verbing”.
in many instances, therefore, both constructions are fine. for instance:
i need to get a new pair of shoes to run --> this sentence implies that “to run” is the ultimate goal (which, presumably, hasn't yet been achieved). in other words, according to this wording, i can't run until i get a new pair of shoes; therefore, “to run” is the ultimate goal or purpose of getting a new pair of shoes.
i need to get a new pair of shoes for running --> this sentence just means that i need to get a new pair of running shoes (= shoes whose purpose is oriented toward the general process of running). this sentence is different, in the sense that it doesn't portray the act of running some sort of remote goal or purpose that hasn't yet been achieved; it merely identifies the reason why i'm getting the shoes.

here's a pair of examples that is a little more like the sentence here:
our company needs to create a new position to manage shipments --> here, “to manage shipments” is a remote goal that has not yet been achieved; in other words, our company probably doesn't even have a shipping and receiving department yet. therefore, we need to establish a new position with that ultimate goal.
our company needs to create a new position for managing shipments --> here, “managing shipments” is just stated as a general purpose; it's probably something that our company already does, but, for some reason, it has now become incumbent upon us to create a separate department for it.
我的理解是，to do是更倾向于ultimate goal。
for doing更倾向于要这样做的原因.
这里的generate it更多的是表目的，用for doing的话，就成了burning calories 是为了generate body heat.不符合常识，动物不是为了generate body heat才burn calories。

找到了更多关于for doing 和to do 的区别题
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
选D
provide support/help/assistance to sb(援助对象)，所以应该用for。classifying强调动作，classification强调这个system的存在。

2、Warning that computers in the United States are not secure, the National Academy of Sciences has urged the nation to revamp computer security procedures, institute new emergency response teams, creating a special nongovernment organization to take charge of computer security planning.

(A) creating a special nongovernment organization to take

(B) creating a special nongovernment organization that takes

(C) creating a special nongovernment organization for taking

(D) and create a special nongovernment organization for taking

(E) and create a special nongovernment organization to take
选E，Stuart大神（G800）的说法是
We use the infinitive form of the verb ("to take") since we have back to back verbs. "To create [it] to take" is stylistically superior to "to create [it] for taking". Accordingly, (E) is better than (D).

3、Noting that the company's network is vulnerable to viruses and spyware, the consultant has urged Infotech to upgrade its protections software, institute new policies for exchanging sensitive information, assembling a special team of information technology specialists to manage network security protocols

A) assembling a special team of information technology specialists to manage
B) assembling a special team of information technology specialists for managing
C) assembling a special team of information technology that manages
D) and assemble a special team of information technology specialists for managing
E) and assemble a special team of information technology specialists to manage
选E，此处的manage也是更多表示一种目的（haven't been achieved)
~~如果有更多的题目，大家一起讨论呀~
感觉这个更大程度上是考语义~~都不是绝对错误的。

(*@ο@*) 哇～！看了中文解析明朗了好多~谢谢helr大神！！！
大神~想问下解释中
The plan is to kill him.正确
The plan is killing him.为什么是错的呢？
可以理解为这个plan正在扼杀他吗？is killing表正在进行时？？
还是说kill这个动词是瞬间动词？
那么这下面几个句子是否正确呢？
Making the plan is killing him.
Executing the plan is killing him.

(1) Jack wishes that MC will win the match.
(2) Jack expects MC to win the match.
我知道expect+sb+that的结构是错误的
那么expect that+从句的结构呢
求指教~

第一个问题：首先，如果is killing表示正在进行时的话，就不在咱们讨论的范围内了。因为那个时候的kill其实是一个纯粹的动词，不是动名词也不是分词，和to do不是一个层级了哈，不能比较。当然，The plan is killing him这个句子是错误的，这个原因是，计划不能主动杀人嘛，只能是人杀人或者执行计划杀人什么的。

第二个问题：expect + 从句也是不正确的。在宾语和宾补上出现不定式和从句的关系，都是按照谓语动词的约束力来决定。

毕老师您好，

本想发消息，打完了发现不是好友不能用这个功能。只好借楼主宝地一用了（楼主请见谅）
看到了毕老师您新上线的gmat.la 我想说，真的是为广大G友提供了一个刷题和备考的平台，真是功德无量。非常感谢！！

请容许我提出一个小小的建议（这个很可能是我的显示屏的问题，如果是请忽略我这message）。我觉得字的颜色实在是太浅色调了，基本是淡灰色的，看的时间长了眼睛非常的疲劳，毕出老师是不是可以在升级的时候把字体的颜色调深几个色调呢。非常感谢！

中国农历新年在即，在此给毕老师摆个早年！祝贺毕老师在新的一年里心想事成

此致敬礼
