"impersonal passive voice"的定义和意义

What is the "impersonal passive voice"?

Impersonal passive voice is a grammatical structure where the subject of the sentence is not specified, focusing instead on the action itself. This form is often used to create a sense of objectivity or to generalize statements. In English, this is typically achieved using "it" as a dummy subject, as in the sentence "It is believed that the event will happen." Here, the action of believing is emphasized rather than who is doing the believing. The impersonal passive voice is useful for making statements that apply broadly without identifying a specific actor.
