关于to do vs. for doing新的想法

pussydoll

不是NN，只是关于这个迷思的自我思考，欢迎大家一起讨论

1. for doing 和 to do都是对的且并没有优先等级划分，能表达出句子的intended meaning才是最佳。

2. 我并不赞同“to do表目的”这个说法。我认为for doing更具有目的性，且带有一定的因果逻辑意味，而to do只是单纯表达一个动作之后紧接的动作。

    如果一定要翻译成中文的话，我认为to do翻译成“去做”，for doing翻译成”为了什么而做“

    e.g.   
               I go to the library to study.
               我去图书馆去学习。

               我只是单纯的去图书馆去学习，这并不是表达我的目的，to study表达不出我是因为要学习而去图书馆，仅仅是单纯的去而已。（我语文不好，见谅。）


               I study GMAT for attending an MBA Program.
               for attending an MBA Program表达出了我是为了上MBA才去学的GMAT，我自己认为有一点因果逻辑的意思，for doing更有目的性。


我不知道我想的对不对，各位?一起爬来讨论

而且欢迎大家把这个想法带到to do vs for doing的经典例题中，感觉都成立的。

我提供下题干：

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.

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

Most states impose limitations on the authority of the legislature to borrow money, with their objectives being to protect taxpayers and the credit of the state government.

再战请勿拦

感谢，也推荐你看这个，我觉得讲的很清楚，基本和你说的意思差不多的。

另外在Manhattan里面发现了一个例外：Wrong:The building WAS DEMOLISHED to avoid falling downaccidentally.


In the above example, the subject of the main verb was demolished is the nounbuilding, which is also the implied subject of the infinitive to avoid. However, a building cannot avoid something intentionally. Thus, the sentence above isnonsensical. Now consider this example:


Right:The building WAS DEMOLISHED to keep it from falling downaccidentally.——building 不是keep的动作发出者但依然正确


The subject building would normally be the implied subject of the infinitive tokeep. However, it refers to building. Since building is the object of theinfinitive, the version above is fine as written. (Assume that the same unnamedpeople who demolished the building wanted to keep it from falling downaccidentally.)

以及我总结了一下大家对这类问题的讨论，打算以后按以下方法实践：
step1：用动作发出者问题判断，如果to do 之前没有发出者就只能用 for doing，
例外：被动语态之后的 todo+do的宾语=被动语态的主语 且 do动作发出者是隐藏的被动语态be done by sb. 的这个sb. （即这个动作的主谓宾齐全且清晰）这种时候可以使用to do：
e.g. The building WAS DEMOLISHED (by someone) to keep it from falling down accidentally. ；
step2：如果判断不出来就先看其他split，(因为很可能是interchangeable的或是to do 更优)，||
step3: 放到最后只能用这个spit的适合再看Ron的方法——是前一个动作的直接结果/目的还是长远目的
Final step: 如果还是都可以就选to do ?但时间关系，估计考试的时候只到step1了
