A good way is to listen to English speakers and try to mimic their sentences. Also, it's extremely important to talk to native speakers, and work on the natural flow of conversation. Hope this helps! :)

Hi Chiara! The only way I know to improve in English and in other language is to speak day one. Find someone on Italki or in real life and speak. It will be hard and you will do a lot of mistakes but it is ok. Making mistakes will improve your skill very quickly because you will remember for a long time. Just try to speak everyday and think in English (very important). ;-)

It's easy .just try to talk to some one in english maybe an hour a day you'll be confused and make mistakes ...by the time mistakes will decay

sse chiara,there is nothing in short,every work take a time i recommend you reading speaking listening more than more,,,i think its best solution all the time
