We'll never forget the day which my classmates and I paid a visit to a chemistry factory last week. It was a larger one with nearly 2,000 workers. It looked a garden and we could see colorful flowers, grass and trees anywhere. We also visited some workshops and saw workers worked very hard. We talked with them and learned a lot of. We understood them further. On the way home we felt tiring. We all thought that we had a very good day. We real hoped that we could get more chances of leave the school and learn social experience.
