Thank you, William!

Your responses are so interesting it's tempting to want to talk about them more than correcting. However, here goes: In response one I'd write: One can easily change jobs, but it is not so easy to change homes. (Their is becoming more acceptable again as a singular...but homes should definitely take the plural, as should jobs. You can reword the sentence if you want home or job to take the singular form). For response two I'd write: Italy is one the first countries in the world (since when? westphalian sovereignty?) with significant emigration of young adults. At the same time, there are heavy immigration flows from North Africa and Eastern Europe. The population of the country has radically changed in the last few years and being able to depict the current demographic situation is practically impossible (arduous instead of practically impossible?), as well as pretentious (is it pretentious if the government wants to do a census? - I feel that in English 'pretentious' is an emotionally loaded word more so than perhaps in other languages). It would be like taking a picture of a running animal. What has not changed at all is that all young Italians want to go (visit? move? try to use a more precise word) abroad. There is no right answer. If one wants to live in a foreign country for more than six months then [change to then] they should try to do their best to [remove in order to] speak the native language. Living far from home can become very challenging if one decides to isolate and not to embrace the native language of their host country.
