Opowiadanie- prosze o pomoc w sprawdzeniu

Witam!

Proszę Was bardzo o sprawdzenie pracy i wyłapanie błędów. Oto ona:

When the classroom door opened, everybody went silent. Our principal Mr.Piakowski came into our class with angry face looking at everyone. We have already known what was the reason of his visit. Five people, including me forced into school last night. The reason was bad marks and we would like to burn our Marks Book Unfortunately, our school caretaker caught us when we were escaping the building. Mr. Piakowski took us from the class to his office.
‘I don’t know exactly what I have to do with you. It is first time when someone did an awful thing in this school’, Mr.Piakowski said angry after few minutes.
‘ We apologize, it was stupid idea to forced into school. We won’t do this in the future’, I replied very quietly.
‘I will punish you only, believe it’s very kind, because I should expel you from this school. You will have to help Mr.Sylwester for 20 hours’, He said and finished our conversation.
We were so happy about this punish- we were thinking about worse punishments. We started next day- Mr.Sylwester was very kind, older man. Fortunately we had not to do anything. After few hours he made something unexpected- he showed us secret places at school. There were a lot of interesting things- school medals, and old embrasure.
Our punishment changed into very interesting trip in school. We get to know many interesting things about school, and we are waiting for next hours of our punishment to spend it with Mr.Sylwester.


Mam nadzieję, że dużo tego nie ma:)


Z góry dziękuje

Hmmm, nie wiem czy wszystko co trzeba, ale troszkę pozmieniałam. Mam nadzieję że się w tym zorientujesz. A, niektóre uwagi to raczej sugestie niż poprawki, więc spokojnie... bardzo sympatyczna praca tak w ogóle :)

We already knew (jest "already", ale w opowiadaniu używasz past simple) what the reason of his visit was (bez inwersji).
including me, broke into the school
kolejne zdanie jest dziwne, może lepiej: we wanted to burn our Marks Book because of our bad marks, nie wiem

'I don't know exactly what I have to do with you (nie jestem pewna, ale może naturalniej powiedzieć "what has gotten into you"? to twoje jest dla mnie trochę niejasne). It is first time that someone did (może dodać "such"?) an awful thing in this school', Mr.Piakowski said angrily (nie: angry, przysłówek!) after A few minutes.

'I will punish you only, believe it's very kind ("of me"?), because I should

We were so happy about this punishMENT - we were thinking about worse punishments (może "penalties" żeby nie powtarzać?). We started the next day - Mr.Sylwester was very kind, elderly man. Fortunately we didn't have to do anything. After A few (few: mało, a few: trochę, kilka) hours he DID something unexpected - he showed us secret places at school. There were a lot of interesting things - school medals, and an old embrasure.
