I went to the Shanghai World Expo this summer holiday. I went by plane with my classmates. We set off in the morning. It took us about two hours to get there. There were more than two hundred pavilions in the Expo. We visited some national pavilions, such as China Pavilion, Japan Pavilion and Germany Pavilion. There were too many people, so we had to wait in lines for our turns to go in. All the pavilions were beautiful. We liked them very much.
