The Great Wall is known as one of the wonders of the world. Every year thousands of tourists from all over the world come to visit this place of (interest) in China. Last Saturday I went to the Great Wall some of my friends. It was a sunny day. On our way up, we
saw many volunteers (志愿者) keeping working in the sun. They helped the elders with their bags, (take) photos for some tourists and answered people's questions. Though they were very , they didn't stop to have a rest. We were deeply moved when we saw this. Just at the moment, we saw (an) little boy standing alone and crying. We went over and asked what (happen) to him. From his answer we knew that he couldn't find his mother. We told him not to (worry) about it and then we tried to get in touch with his mother with the phone number he gave us. Twenty minutes (late), his mother turned up. When she saw her son, she was very excited and thanked (we) with tears in her eyes.
That day we not only enjoyed the beauty of the Great Wall, but also felt the warmth of the society. everyone can reach out a helping hand to others, the world will be more and more harmonious (和谐的).
