标题: 关于不定式的逻辑意思（manhattan） [打印本页] 作者: Sybil_Wang 时间: 2014-11-3 07:20 标题: 关于不定式的逻辑意思（manhattan） 这是在manhattan上看到的两组句子：
Wrong: The building was demolished to avoid falling down accidentally.
Right: The building was demolished to keep it from falling down accidentally.
Unlikely: A plan conquering the world is in his files.
Unlikely: A plan that will conquer the world is in his files.
Probable: A plan to conquer the world is in his files.
第一组句子不能用building to avoid是因为building是inanimate subject，而第二组可以是因为有人做了plan去conquer。我的问题是，不能有人造了building去avoid吗？其实在我心里1.2两组非常像！！在考试中要如何区分啊！！！求大神解答！！！

lz啊！！to avoid falling down错了是因为人不能falling down，而The building 无法avoid 。to conquer the world 或许对是因为人可以conquer the world 。两者完全不同！作者: yitingwang 时间: 2015-1-27 23:52
摘自曼哈顿 Ron大神的解释
* If "to + verb" expresses the purpose of an action, then the subject of the action should also be the one whose intention is "to + verb".
E.g.,
Tom swam a mile three times a week to boost his stamina.
(Who swam a mile three times a week? Tom did. Whose intention was to improve his stamina? Tom's.)
* "To + verb" can also qualify adjectives/descriptions. In this case, the subject of the previous part is the thing being VERBed"”i.e., the object of the verb.
Ok, that rule looks like nonsense in rule form. (I wrote it myself, and it still looks like nonsense.) So, just remember some examples.
This book is hard to read. (Someone is reading the book.)
Some mountains are just too tall to climb. (we're talking about climbing mountains)
Two different things.
