英语中的不及物动词为什么不能有被动语态？

Question

英语中的不及物动词为什么不能有被动语态？请举几个简单的例子。

Answer 1

英语中,不及物动词没有被动语态。
被动语态是由原主动句的宾语变成被动句的主语。而不及物动词没有宾语，所以就没有被动句。
英语里面只有后面可以直接跟宾语的动词,也就是及物动词才有被动语态。

1) 不及物动词或动词短语无被动语态：
appear, die disappear, end (vi. 结束), fail, happen, last, lie, remain, sit, spread, stand
break out, come true, fall asleep, keep silence, lose heart, take place.
After the fire, very little remained of my house.
比较： rise, fall, happen是不及物动词；raise, seat是及物动词.
(错) The price has been risen.
(对) The price has risen.
(错) The accident was happened last week.
(对) The accident happened last week.
(错) The price has raised.
(对) The price has been raised.
(错) Please seat.
(对) Please be seated.
要想正确地使用被动语态,就须注意哪些动词是及物的,哪些是不及物的.特别是一词多义的动词往往有两种用法.解决这一问题唯有在学习过程中多留意积累.
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
This key just fits the lock.
Your story agrees with what had already been heard.
3) 系动词无被动语态：
appear, be become, fall, feel, get, grow, keep, look, remain, seem, smell, sound, stay, taste, turn
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.

Answer 2

不及物动词就是不能直接加宾语的动词。所以没被动。被动就是把宾语变为主语，
如：He gets up at 6:00没法改为被动。
