'It' (ja bym tutaj dala 'this') seems to have a lot of benefits, such as promotion (ale czego? musisz napisac). However, as everything (tutaj wg mnie brakuje slowa 'else') it does 'have also' (zla kolejnosc slow) certain drawbacks that people tend to forget about.
There is no denying that (przedimek) country or (przedimek) city becomes more popular and a lot of tourists from all around the world come to visit it. What is more, (przedimek) government usually receives 'some money' (moze ujmij to na wyzszym szczeblu, np. 'grants' 'donations') for preparing (ja bym tutaj dala jakie, football, basketball) pitches(,) (nie dawaj przecinka jak wymieniasz tylko jedno zjawisko ) gyms from international sponsors. 'Conditions' (nie za bardzo trafne slowo) become better and also sport promotion 'grows' (nie, poszukaj innego slowa, wiecej academicki, np 'increases'). Last but not least, in przedimek) country where (przedimek) competition takes place, 'people sports interest increase' (nie, tu masz zle, to chyba slowo w slowo z polskiego, ale musisz to inaczej...peoples' interest in sports increases'). (przedimek) big event creates a huge opportunity to meet 'big' (wszystko jest tylko 'big' staraj uzyc sie innych synonimow - np. famous, well-known...pokaz ze masz szeroki zakres vokabulary) stars like Ronaldo or Messi 'near home' (ujmij to inaczej). It is 'the'(zly przedimek) chance to see the sport from a new perspective.
For instance, if the country or (ja dalabym przedimek) city is badly prepared, many people might complain and regret coming (ale gdzie? do tego 'country' napisz wiecej precyzyjnie). Furthermore 'this' (nie wiem do czego to 'this' sie odnosi) area may become (przedimek) notorious place. Another problem appears when (przedimek) government spends 'a lot' (daj inne 'wyzsze' slowo, np. a vast amount) of public money on the event. (przedimek) public could be 'unpleased' (nie, tutaj masz zle, slowo jest 'displeased') and start moaning. Apart from that, for many citizens (przedimek) competition may bring troubles. For example tourists from all around the world 'do not know' (mozna tez' are not familiar with') Polish law and might 'badly behave' (zla kol slow) on the streets and in other public places.
The decision of whether (cos brak) 'prepare' (daj inne slowo) competition or not, should be a responsible decision.
Uwazaj na te przedimki( a, an, the). Musisz nad nimi popracowac jeszcze.
