【1】Entering a study abroad program was a personal program for myself. College had not been fun up until that point. I was looking for excitement. After meeting a guy who loved to travel, he convinced me that studying abroad was one of the best decisions he had ever made and that I should try it. Immediately I visited my study abroad office and discovered many choices. I only spoke Spanish, but not fluently enough to feel comfortable in a program that was based in Spain or Mexico. This meant I needed a country that spoke English. Finally I chose the University of Central London.
【2】Many people hesitate before studying abroad because they think they__________. I went to college on loans(贷款), so a semester abroad would be no different. The additional expenses, such as food and travel, were the most expensive part of the trip. Any student travelling abroad received part of a grant donated to our school. This took almost $ 2,000 off the cost of my trip.
【3】Looking back on my experience years later, I am grateful that I took the chance and studied in London. I made a number of friends in London with locals, who are willing to help me anytime. I never felt unsafe because they would show me how to live in London, where to go and how to get anywhere I needed to go.
【4】My favorite memories in London is turn around my classwork. When studying abroad I took an English class that focused on British humor. During this class we watched British films and went to live performances. Before this class, I never understood British humor, and now I enjoy it more than American humor. My favorite class was art history. I cannot express to anyone how interesting it was to take art history in London.
【5】When people ask me if I would study abroad again, I exclaim, “yes!” You will never learn any lessons or information like you do when travelling abroad to a foreign country. As a person you will grow independent from everything. You will learn how to make friends and survive alone on your own. You will also learn to respect and understand other cultures.
