求详细解答：写作。 假设你

Last summer vacation, my parents and I paid an eight-day visit to London. We flew from Hong Kong and the flight lasted for about 14 hours. During our stay there, not only did we visit Big Ben, the London Eye, Buckingham Palace, but we also took a boat trip on Thames River. On the last day during our visit, I met an online friend there in a coffee bar while my parents went shopping. What impressed me most was that people in the hotel were so friendly that they would do anything they could for you, and I found that the best way to explore the city was to go around with a map of it.      答案不唯一
