Объяснение:

Present Perfect-действие закончилось но мы не знаем когда, есть результат. Я уже прочел 5 книг. I have already read 5 books. (мы не знаем когда он их прочел, но знаем сколько уже прочитанных им книг есть).

Present Perfect Continuous- действие началось в прошлом и продолжилось до настоящего момента. Результат здесь не важен, важно как долго длилось действие. Я читаю эти книги уже неделю. I've been reading these books for a week. Я начал их читать неделю назад и возможно я их еще не закончил читать (мы не знаем этого)
