(NOTE: "Got" is used as the past participle of "get" in both American English and British English. "Gotten" occurs only in American English.)2. I have got a problem. In this sentence, "have got" is NOT present perfect. I've got a problem = I have a problem. The expression "have got" means "have" and is common in informal spoken English. Its meaning is present; it has no past form.Typically, the present perfect is used in sentences with "already", "yes", and "just", but in some situations the simple past is also commonly used with these adverbs in informal English, with no difference in meaning.Заодно упомяну еще две формы для выражения долженствования: I have to и I have got to, где вторая также характерна для spoken English. Наконец, замечу что добавление "got" и в значении "иметь", и в значении "долженствовать" более характернo для BrE.
