Present Perfect czy Present Perfect Continuous????

[Gość: Chello]

He .......... (work) in comedy since he was fifteen and ......... (perform)
on the stage for many years.

Dodtakowo mam pytanko: czy jak zdanie zaczyna się od "SINCE" potem musi być
Past Simple???

[Gość: cc]

Pierwsze myśli:

ad. 1 - Perfect Continuous
ad. 2 - nie, potem musi być past simple, chyba że SINCE znaczy "ponieważ" -
wtedy wszystko może być

Zależy co chcesz wyrazić, co masz na myśli. Bo teoretycznie możesz tam wstawić
KAŻDY czas. Język jest narzędziem a nie klatką. Możesz np. do pierwszego
wstawić Present Perfect Continuous (he's been working) a do drugiego present
perfect... nie ma dobrej odpowiedzi. I wierz mi, jestem anglistą.

[Gość: OK]

He .......... (work) in comedy since he was fifteen and ......... (perform)
on the stage for many years.
He has been working in comedy since he was fifteen and has been performing on
the stage for many years.
Ja nie mieszałabym tak z różnymi czasami. Perfect contin. w obu jest OK.

1. He has been working in comedy since he was fifteen and has been performing
on the stage for many years. (GOOD)

2. He has worked in comedy since he was fifteen and has performed on stage for
many years. (GOOD)

3. He worked in comedy from the age of fifteen and has performed on stage for
many years. (GOOD)

4. He worked in comedy from the age of fifteen and performed on stage for many
years. (GOOD)

1. = 2.

3. and 4. have slightly different meanings.
