被动句是从主谓语之间的关系上说的。当谓语动词所表示的动作行为的接受者出现在主语位置上充当句子主语时,我们就说整个句子是被动句。这一点古今汉语是一致的,但古今汉语的被动形式却很不相同。例如:郤克伤于矢。(《左传·鞌之战》)这是用介词“于”放在谓语动词后面,引入动作行为的主动者“矢”,使受事主语“郤克”具有明显的被动性质的例子。 Passive sentences are the relationship between the principal and the predicate. When the recipient of the action expressed by the predicate verb appears in the position of the subject as the subject of the sentence, we say that the whole sentence is a passive sentence. This is ancient and modern Chinese are the same, but ancient and modern Chinese passive form is very different. For example: but grams in the vector. This is an example of the passive “nature” of the victim subject “Kuke”, which is introduced by the preposition “Yu” behind the predicate verb to introduce the action vector.
