Hi !
Czy te zdania są poprawne gramatycznie ?
Jessica has left the pop group 5 Alive.
At a press conference last night Jessica has explained that she wanted to do a solo album.
A close friend revealed "There was a lot of disagreements in the band lately. Jessica decided that leaving the band was the only way forward."
Czy to jest dobrze ?
jaki czas z last night?
jaki czas z lately?
last night past simple ? z lately p.p.continuous
Czyli czasy źle ale wszystko ?
there have been - jaki continuous od "to be"?

reszta jest ok wg mnie.
