1. She has been working here since 2020. *Ошибка*: Неправильная форма глагола. После `has been` должен идти глагол в форме Present Participle (с окончанием -ing). *Исправление*: `work` -> `working` 2. They played tennis two hours ago. или They have been playing tennis for two hours. *Ошибка*: Использование `ago` с Present Perfect Continuous (have been playing) неверно. `Ago` используется с Past Simple. *Исправление*: Убрать `ago` и оставить Present Perfect Continuous, либо использовать Past Simple. 3. I have been writing emails all morning. *Ошибка*: Неправильная форма глагола. После `have been` нужен глагол с окончанием `-ing`. *Исправление*: `write` -> `writing` 4. We have been watching TV for 5 hours. *Ошибка*: C `since` нужно использовать конкретное время, а с периодом времени - предлог `for`. *Исправление*: `since` -> `for` 5. He has been studying for the test. или He has studied for the test. *Ошибка*: Страдательный залог (`been studied`) здесь не подходит. Предложение должно быть в активном залоге. *Исправление*: Изменить на `He has been studying` или `He has studied`.
