4 She has studied/has been studying all day.
5 I worked/have been working without a break since 8 o'clock.
6 I have been walking/walked to the park last week.
Решение
Present Perfect Continuous (have been + -ing) — длительное действие, которое продолжается до сих пор или только что закончилось (all morning, all day, since o'clock). Present Perfect — результат (его нет здесь, ушёл — и сейчас там). Past Simple — точное время в прошлом (yesterday, last week).
all morning — длительность: have been talking.
«его нет, потому что ушёл на работу» — результат, он вернётся в : has gone (has been going означало бы «ходит регулярно»).
yesterday — Past Simple: cleaned.
all day — длилось весь день: has been studying.
since o'clock — с момента, действие продолжается: have been working.
last week — Past Simple: walked.
