主动形式表被动语态的情况有哪些

那些我都知道.我想问:不定式里面一般什么adj后面可以主动表被动?还有没有其他特殊的地方?
eg.This is a new model machine which is easy to operate.
A man so difficult to please must be hard to work with.

1. open, lock, sell, read, write, clean, cut, wash, burn, teach, drive, shut 等及物动词在用作不及物动词时，它们的主语为物，可用主动语态表示被动意义。如：
This kind of skirt sells well.这种样式的裙子很好卖。
The car drives well.这车很好开。
2. end, cool, do, print, copy, sell, work out, build 等动词的现在进行时态表示被动意义。如：
Our new teaching building is building.
3. look, taste, smell, sound 等连系动词用主动语态表示被动意义。如:
The dress looks nice on you.
The dish tastes good.
4. be worth doing 结构中doing为主动语态表示被动意义。如：
The topic is well worth talking about.
5. want, need, require等动词表示“需要”，后面常可跟动词—ing形式表示被动意义，相当于to be done 。如：
All these computers need repairing.=All these computers need to be repaired.
6.在too...to...及enough to结构中有时表示被动意义。如：
The problem is too difficult to solve.
