be done 是谓语还是非谓语
be done是英语中经常出现的一种结构,它的意思是被怎么样,是一个被动语态。
be done 是谓语还是非谓语?
be done是谓语动词结构,表示被动。
例如:
He was knocked down by car.
他被车撞倒了。
knock 这个动作是car发出来的,He是这个动作的承受者。
用动作的承受者来作主语时,谓语动词词用被动语态:be done。
主语是指动作的发起者或执行者。
宾语是指动作的承受者或者对象。
be done一定是被动语态吗?
1、be+done可以是被动语态,也可以是系表结构形式。被动语态中,done可以带by短语,而系表结构中done相当于形容词,不带 by短语。
例如:
The question is settled.(系表结构)
Such questions are settled by us.(被动语态)
The composition is well written.(系表结构)
The composition is written with great care.(被动语态)
The job was well done.(系表结构)
The job was well done by a skilled worker.(被动语态)
2、许多动词(broken, interested, shut, worried), 既可以用做形容词,也可以在被动语态结构中做过去分词。句中如果有by,通常是被动语态。
例如:
I was worried abeutyou all night.(表状态)
I was worried by mosquitoes all night.(表动作)
The glass was broken by Jack.(表动作)
The glass is broken. (表状态)
be done 和done区别:
1、be done:
be done属于被动式的原型。它有is done,are done的单数和复数形式,作谓语。
如:
The work can be done this week.
2、done:
done是过去分词,它不能作谓语,但可作补语,表语。作定语和状语,表示和所修饰词之间的被动关系,
如:
The meeting held yesterday is very important.
