　　Shenzhen is well-known as a city of technology and innovation. Last week, our school held a science festival. Its purpose is to develop students' interest in science and technology.
　　At the festival, some students took an active part in the model-making competition. Many of their robots were the highlight of the festival. They drew people's attention. These robots were in the shape of lovely animals, such as rabbits, monkeys and dogs. They were doing some simple tasks like sweeping the floor and throwing away rubbish. Besides, some other students did science experiments. The students present at the festival were all surprised at the show happily.
