示范答案：
I have been to over 25 countries worldwide. Often, this has been a quick trip or tour of a country, where I can see and do as much as I can in the time period that I have. But I have also lived in two foreign countries: Uganda, where I lived for 4 months, and England, where I have been for over a year. In both situations, I feel I have contributed to the economy of the respective countries. When I was travelling, I spent much money on gifts, food and accommodation, and when I was living abroad I also paid taxes and offered my skills to the country in the form of work.
