被动语态不得无中生有
英语中，不是所有的动词都有被动语态。以下几类动词一般就无被动语态。
一、不及物动词无被动语态
如：appear出现，die死亡，disappear消失，end结束，fail失败，fall下跌， happen发生，last持续，lie躺，remain遗留，sit坐， spread传播，stand站立等；不及物动词短语break out突然发生，come true实现，fall asleep入睡， keep silence保持沉默， take place发生，等等。例如：
The sun appeared on the horizon．太阳在地平线上出现。
He died of an illness．他因病死亡。
He failed in his English examination．他的英语考试不及格。
The book fell off the shelf．这本书从架子上掉了下来。
The accident happened outside my house．这个事故发生在我家房子的外面。
I went to the city，but my brother remained at home．我去了城里，可弟弟却留在了家里。
He was lying in the shade of the tree．他正躺在树阴下。
We stood outside the shop．我们站在商店外面。
He sat in a chair．他坐在椅子上。
A fire broke out in the kitchen．厨房发生了火灾。
比较以下句子的正误：
（误）：The race will be taken place tomorrow．
（正）：The race will take place tomorrow．
（误）：The accident was happened just outside the town limit．
（正）：The accident happened just outside the town limit．

2．I still don't know what _____ while I was away from home．

如：look（看起来），sound（听起来），taste（尝起来），become（渐渐变成），fall（变得）， get（变得），grow（变得），keep（保持），remain（仍然是），seem（似乎），stay（保持），turn（变得）等无被动语态。另外，feel用于“给某人某种感觉”；smell用于“散发某种气味”，等等也无被动语态。例如：
