I just returned from a trip to New York with my high school. But otherwise I went to London, as well as Portugal and France with my family during the summer holidays.
If I lived abroad for 1 year, I would choose an English-speaking country to improve my English. I would like to go back to the United States, since the universities are just too good to appear English well since French people have already experienced and told us. In addition, it would be research for my project abroad.
