    The master 8and suggested, "I'll let you know that you are a great 9. Now go to paint the same painting once again and give it to 10."

    I'm Dave. I'm from the west of Ireland. When I finished university, I1to leave Ireland to find work. Although I2home. I enjoyed living in London for two years. But after that, I felt I needed a3. so I bought a ticket to Ecuador ,a country that many of my friends were talking about. Two months later,4was in Quito，a beautiful city high up in the mountains. First，I explored(考察)the city. Next，I decided to walk on the Camino Real，the most important Inca road. It was hard work. 5the views(景色)were really wonderful. During the walk，there were more and more clouds and it was6to see. Suddenly I heard some magical Irish music. It 7me of home. “How could it be?”I just 8believe it. I thought l was dreaming. The next day, when I came down for breakfast at my hotel. I9found out the truth. 10 was practicing Irish music at the hotel garden(花园). It was an American tourist who was making the magical music of my home!

    On May Day holiday of this year, my parents and I went to the Great Wall. On the way I felt 1, because this was my first visit. I had dreamed 2 this trip many times. We took a train first, and then we took a bus to 3 there. When it appeared in front of me, I couldn't help 4. I said, "What a wonderful 5 it is!"

    When I walked on the Great Wall, I felt very proud because it is 6wall in the world. At the same time, I couldn't believe my eyes. I wondered how the ancient people built it by 7. I wondered how many people took part in building it. It was a mystery to me.

    I almost lost 8 in the beautiful scenery around it. "He 9 doesn't reach the Great Wall is not a 10 man. Now I'm on the top! I'm a true man," I said loudly.

    But, 11 there are many visitors every day, there are many problems for the Great Wall. For example, many visitors throw 12 about or spit on the Great Wall and some visitors 13 carved their names on it.

    As visitors, I think we 14 try our best to protect the Great Wall, not to destroy it. It's our duty. The past is not only for us to enjoy 15 for the people in the future.
