I had never seen such beautiful sights before I visited Paris in 2012. I had saved money for 5 years before I booked my trip to Paris. I was very excited！ Before my trip to Paris， I had never been out of the United States.
　　When I went to Paris， I spent many days touring the city. The city was big. Sometimes I got lost and asked for directions. I asked for directions in French. That was easy because I had studied French for 2 years before I visited Paris.
