Poprawilam, ale niestety muszisz jeszcze duzo popracowac:
When the holiday 'started' (started to czas przeszly i to co napisales,..kiedy wakacje sie zaczely, a masz cos innego na mysli) people ARE thinking about where 'we' (nie licz siebie i mnie to tego 'we'-poszukaj inny odpowiednik) 'go out' (wychodzic-ale gdzie? too niema sensu).
Some people 'decided' (tutaj DECIDE to go abroad, others stay in 'your' (niestety ja niemam kraju, w ktorym oni maga byc - napisales 'w twoim kraju' - ale to jest zle - co masz na mysli to 'w swoim kraju' IN THEIR OWN COUNTRY. In my essay I WILL (dlaczego zapomniales o 'will'?) present THE advantages and disadvantages of spendING (ale co? czego?) in foreign countries.
Journey to foreign countries 'have' (ale journey to l. poj. - journey HAS) many advantages and disadvantages.
To start WITH when we 'going' GO abroad we can improve 'your ours' (a co to jest? popraw) language skills 'for' BY talking with other people. Secondly, we can meet new friends and different interesting people 'with' IN foreign countries, who have 'a' (przed l. mnoga 'interests' nie dajemy 'a') similar interests. We can GO sightseeing landscapes and GET TO 'knowing' KNOW THE culture of foreign countries.
'For going' (to jest zle, napisz GOING abroad 'we' (niepotr) can have a lot of attractions, which ARE not available in 'ours' (nie, sprawdz roznice pomiedzy OUR a OURS, tutaj OUR) countries. We can visit a lot of shopping malls and
entertainments 'etc' (chcialabym odwiedzic to 'etc' - gdzie to jest:-)). Also, 'for' BY going abroad we can learn more 'geographic' (zle slowo) and 'learning' LEARN 'for' THE other countries and regions.
'Spends' (to co napisales to 'wydawanie'- a chiales napisac cos innego, tutaj SPENDING A holiday abroad 'have' (holiday to l. poj-popraw) MANY disadvantages. 'However' (zle uzycie slowo 'however' - niepotr) Going abroad 'is' (po co to 'is' tutaj jest?) costs too much and not everyone has 'a' THE cash for it. 'Persons' (generalnie mowimy PEOPLE who don't know foreign language shall (ale shall WHAT?) a problem 'witch' (zmien to, bo to co napisales to 'czarownica', a w ogole jest zle slowo bo powinno byc WHEN-kiedy) talking with other people.
Another disadvantage of going abroad is this - when we don't know
another 'countries' (tutaj l. poj) we can get lost. In addition when we ARE going abroad to exotic countries we can (we can - ale CO?) ill 'for' WITH 'exotics' EXOTIC 'ills' (daj inne slowo - dis....) and epidemics. ANOTHER problem shall be 'a' THE ignorance of morals IN 'another' (daj OTHER countries and we can be 'seeing' SEEN badly for another people. What is more, in other countries we can be in danger 'for' OF politicAL concerns and 'terrorists' TERRORIST attracts, 'what' (to jest kalka z polskiego 'co'- nie zawsze tak tlumaczymy, tutaj WHICH can break 'ours' (prypomnij sobie roznice pomiedzy OUR and OURS) holiday.
To sum up, A holiday 'have' (popraw, holiday to l. poj) many advantages and a lot 'for' OF disadvantages. In my opinion when we 'decided' DECIDE to go abroad we can 'knowing' KNOW 'a' THE beauty of 'yours' (przypoomnij sobie roznice pomiedzy YOUR and YOURS) countries.
