Present Perfect Simple
Описание:
Present Perfect Simple is used to talk about actions or events that have happened in the past and have a connection to the present. It is formed with the present tense of the auxiliary verb "have" (I/you/we/they) or "has" (he/she/it), followed by the past participle of the main verb. The question form of Present Perfect Simple is created by inverting the subject and the auxiliary verb. To form negative sentences, "not" is placed after the auxiliary verb.
