This part of the extended materials mainly examines the knowledge points of passive voice:

A verb form that explains the relationship between the subject and the predicate verb. There are two voices in English: active voice and passive voice. The active voice indicates that the subject is the executor of the action, and the passive voice indicates that the subject is the receiver of the action. Passive voice is a special form of verbs. Generally speaking, only transitive verbs that need action objects have passive voice.

Passive verbs such as "Bei", "shou" and "gei" are commonly used in Chinese to express passive meanings? . The passive voice consists of the past participle of the auxiliary verb be+ and the transitive verb. The temporal change of passive voice only changes the form of be, and the past participle remains unchanged. The same is true of the changes of doubt and negation.

Intransitive verbs have verbs with the same original object, while reflexive pronoun verbs and copula verbs have no passive forms. Even so, there are infinitives, gerunds, participles and their complex passive structures, plus modal verbs, auxiliary verbs and their interrogative and negative forms.

The following formula takes the verb "do" as an example, that is, the past tense of "do, did" and the past participle of "done", and summarizes the passive dynamics of various tenses in the form of formulas. It must have inspired you. Of course, the passive voice can also be summarized as "being done". That is, "be+ past participle".
