在看manhattan里面讲modifier时说都要求有noun才可以,但有一种例外是“infinitives of purpose can be used with unamed agents in passive-voice sentence”,但是后面又说an infinitive of purpose needs to indicate the purpose of some one...真心给跪了!!求大神指点!!!
manhattan 4th: In each case, the subject I makes sense: I was whistling "Beat It, " I was concentrating, I wanted to free my leg. Make sure that these modifiers have a sensible subject in the sentence. Wrong:The weight was lifted by concentrating. Wrong:The weight was lifted to free my leg.
