Question

老师说带to的动词不定式主动表被动,可我在英语书上找到了这样一个句子She was nowhere to be found?

Answer 1

你问得到位,非常有质量.
1 The question is easy (for sb.) to answer== It is easy (for sb,) to answer the question.
因为你的句子省略了括号里面的逻辑主语,并且完全可以省略.
2 They are nowhere to be found== They are nowhere for you / me to find
因为they是要被find的主体,做主语.如果用主动语态,必须写上for sb这样的结构.
如：They are nowhere for us to find==they are nowhere to be found (by us).
明白了吗?祝你愉快.
