Generally speaking, when emphasizing the receiver of the action, it is not necessary to say the performer or the vague performer, and the passive voice is used more. It should be noted that many places are different from Chinese. Note that there is no meaning of "Bei …" in Chinese, but "Bei" is used dynamically in English. It should also be noted that English passivity often comes from "by", and phrases with the preposition "by" are often not passive, but a systematic structure. There are some unusual phenomena, such as …know to man, on foot walking (Americans sometimes use foot), in carraige and so on.
