    Last summer I had a chance to visit Paris. That attracted me most was the Eiffel Tower, where has become a symbol of France. I was deeply impressed by their height. I have never seen such tall building before! It is made of iron and it is about 7000 tons heavy. There have 1711 steps from the bottom to the top. Climb the tower made me very tired, but I was very exciting. I took a lot of photo in Paris.

    I have much memories and experiences to share. I will remember my trip to the France forever!
