Something special I did during this vacation

Something special I did during summer vacation is Kaigaikenshuu because this experience is to be the best treasure I have ever lived. It was first time to go abroad and live other country people. So I was nervous before arriving at Minnesota. As expected, I was troubled many things. For instance my English skill, bocurvraly, grammar or difference of culture, difficult of communication and so on. It was stimulated for me and I thought I have to study harder than now. So my consciousness against English was changed after going Minnesota. It is important for me to study from now on. I'll go English Lounge or International community center to have some chances using English. (116/638 words)
