Manhattan Chapter 13 P250 上的一个例子：Wrong: The building was demolished to avoid falling down accidentally Right: The building was demolished to keep it from falling down accidentally. 划线部分改动的原因在于，building 在上一句中是implied subject, 但是building cannot avoid something intentionally。 但是P253 页又有一例：Right: A plan to conquer the world is in his files. 同样是表目的，并且a plan itself cannot conquer the world.但 这句话就是对的。 这两句话唯一的区别在于第一个里不定式是做状语，第二个不定式是做定语。是不定式在做状语的时候就要注意逻辑主语的问题么？还是有别的原因？麻烦大神们回答一下呀~
Wrong: The building was demolished to avoid falling down accidentally Right: The building was demolished to keep it from falling down accidentally 其实考点split在于avoid doing和keep it from doing——it是否要增加的问题， 当遇到“v.+prep.+ doing”或 “v.+doing”时，先看v.和doing的逻辑主语是否一致，如果不一致，必须补宾语。。。。LZ看一下keep from和avoid能是the building本身发出的动作吗？？？必然不是，那就要加上it。。。。BTW——og上有这种类型的题，考点就是keep it from和avoid的选择
