參考詞匯：文化沖擊culture shock
Dear friends，
I am honoured to deliver a closing speech on behalf of all the Chinese students in the camp．

Before I came to Canada，I had made careful preparations for this camp．However，I still experienced some unexpected challenges，such as the difficulty in making myself understood，talking with others from several countries，and dealing with culture shock．With great patience and kindness，the organizers helped me out．The four weeks in the camp has changed me greatly．Not only did I improve my oral English，but I also made lifelong friendships．Most importantly，I became more confident．So now I would like to express my great thanks to all the people who contributed to the camp．
