谓语是及物动词的主动句的为什不能改为被动句？

谓语是及物动词的主动句的为什不能改为被动句？首先，你这个问法存在问题！比如：主动句I bought a book . 改成被动句 A book was bought by me.完全可以！

我给你罗列一下不用被动语态的情况
1) 不及物动词或动词短语无被动语态（即多数的瞬间动词）： 　　appear, die(死亡),disappear（消失）, end (vi. 结束), fail, happen, last, lie, remain, sit, spread, stand 　　break out, come true, fall asleep, keep silence, lose heart, take place. 　　
e.g After the fire, very little remained of my house. 　　
2) 不能用于被动语态的及物动词或动词短语： 　　fit, have, hold, marry, own, wish, cost, notice, watch agree with, arrive at / in, shake hands with, succeed in, suffer from, happen to, take part in, walk into, belong to 　
e.g This key just fits the lock. 　
3) 系动词无被动语态（keep除外）： 　　appear, be become, fall, feel, get, grow, look, remain, seem, smell, sound, stay, taste, turn 　
e.g It sounds good. 　
4) 带同源宾语的及物动词，反身代词，相互代词，不能用于被动语态： 　　die, death, dream, live, life 　　She dreamed a bad dream last night. 　
5) 当宾语是不定式时，很少用于被动语态。 　
(对) She likes to swim. 　　(错) To swim is liked by her.

拿个具体的例句来看看怎么回事。 再看看别人怎么说的。
