主语+seem+adj+(for+sb)+to+do+动词不定式用主动形式表被动意义

Question

如题所述

Answer 1

有一些形容词后面可以接动词不定式，在某些形容词后，动词不定式与主语构成动宾关系，这时动词不定式可以用主动形式表示被动意义，如：
This rule seems easy to remember.
This problem seems difficult to solve.
She seems very nice to talk to.
Mr. Lee seems hard to please.本回答被网友采纳

Answer 2

Mary seems easy to teach.（玛丽似乎很容易教。）这句话能转换为：To teach Mary seems easy.（教玛丽似乎很容易。）所以原句中不定式分句的逻辑宾语是句子的主语Mary，逻辑主语是people who teach。那么，不定式分句to teach是逻辑上的主动分句表示主动的意义，并非主动分句表示被动的意义。
