Last summer, we are selected by our school to go on a study tour in Britain. On the morning of June 27th, at the moment we stepped out of the airport, we were surprised to find our home-stay families waiting to pick them up. Later we went to different home-stay families as scheduling, where we had typical English food and chatted happy.

The next day, we went to Westminster College to attend a presentation about a college. A professor gave us a vivid but interesting introduction. Over the next few days we visited so many famous tourist attraction. On the last day we had a farewell party, at which we gave fantastic performances, included singing and dancing. I think the study tour is unforgettable, which we have learned a lot.
