Complete the sentence with the verb in the Present Perfect Continuous. Write down the correct form of the verb. Peter _______ (sleep) for ten hours! Please wake him up.

The sentence needs to be completed using the Present Perfect Continuous tense. The Present Perfect Continuous is formed using: `has/have + been + verb-ing`. Since the subject is "Peter" (which is singular), we use "has". Therefore, the correct sentence is: Peter **has been sleeping** (sleep) for ten hours! Please wake him up. Разъяснение на русском языке: Предложение нужно завершить, используя время Present Perfect Continuous. Present Perfect Continuous образуется с помощью: `has/have + been + глагол-ing`. Поскольку подлежащее "Peter" (единственное число), мы используем "has". Следовательно, правильное предложение: Peter **has been sleeping** (sleep) for ten hours! Please wake him up. Ответ: has been sleeping
