The second argument is THAT students look pleased 'what' (kalka z polskiego 'co', ale po ang. jest inaczej 'daj tutaj 'which') might suggest that 'learing' (blad ortog) in this school 'don't' (jakie to kolokw. tutaj piszesz? napisz to poprawnie) cause 'studentes' (ortog) problems.
I wouldn't pick photo number 2 because this school 'offer' (ale 'this school' - 'it' to 3 os.l.poj) traditional model of studying and I want 'to modern' (tego nie rozumiem) model. In this school I 'don't' (tutaj mowisz o przyszlosci, to napisz to tak) take part in social events because (ale kto? musisz napisac) don't offer this.
1. If we look at 'disadventages' (ortog) we can say that studying abroad is expensive. We must pay high 'tution' (ortog) fees. Another 'disadventages' (ortog i tutaj l. poj) is that we can feel homesick and lost in (tu brakuje przedimka) new 'enviroment' (ortog).
2. One 'adventages' (ortog i l. poj) is that (ale co? musisz napisac) improve language skills 'talking to people exchange' (tego nie rozumiem). Another 'adventages' (ortog i l. poj) of taking part in (przedimek) international exchange is that (ale kto? musisz napisac) learn about other cultures 'exploring the world' (cos mi tu nie gra z tym).
