I am writing to invite you to attend this year’s (tutaj trzeba napisac o co chodzi) conference. It will be held in (przedimek) rural area (brak slowa) Sweden ( a dokladnie gdzie, Sweden to duzy krak) from Thursday 'evenings' (l. poj) to Monday morning in July (data i rok) .
Our conference 'have' (conference to jest -it-3os.l.poj) three 'the' (po co dajesz przedimek tutaj?) aims. (brak przedimka) first aim is (brak slowa) discuss 'about' (To takie polskie - prosze tak tego slowa nie uzywac) how the company can improve its products and services.
(brak slowa) thank managers for their hard work is the second aim. The last aim is the opportunity to get to know each other better and make new 'friends' (dla mnie to slowo nie pasuje - w business nie robi sie friends, ale cos innego) because it is very important in this business.
The Hotel Steffenberg where you (brak modala) stay is located in a modernised castle in Sweden, 200 kilometers from Stockholm airport. From the airport to the hotel is (brak przedimka) 'regularly' (zla czesc mowy) bus hotel service, 'which' (calkowicie zle slowo, tutaj potrzeba 'gdzie') the journey takes 3 hours, so then you can meet new managers (nie jest to za jasne - czy beda czekali na nas, czy w hotelu). The hotel 'have' (dlaczego piszesz 'have' jak hotel to jest it - 3os.l.poj) conference room for 150 people where 'will be held conference' (zle - napisz to biernie) and five meeting rooms where THERE will be 'held' (niepotr - przeciez to jest wiadome) workshops and training sessions.
The hotel has good leisure facilities for example it has (przedimek) excellent spa, nine-hole golf course near the castle and if you want you can use 'for an extra charge' (na koncu zdania) 'with' (zle slowo, daj tu przedimek) pool and sauna. In (przedimek) hotel restaurant 'served are Swedish dishes' (daj to biernie...Swedish..) but if it is requested also other dishes. Evening entertainment is (przedimek) performance young Swedish musician. Moreover at lunch you can listen (cos brak) classical music.
I look forward to see you 'in' AT the conference.
A co z tymi przedimkami (a, an, the). Dlaczego ich uzywasz blednie? Prosze sie ich nauczyc.
