题目：

My cousin Li Ming is a senior three student, who devoted himself to his lessons every day. Last Saturday, as usual, he went to several class. In the evening, he continued to study at home until deeply into the night. He was too sleepy and tired that he couldn’t work effectively. In Sunday morning, he was about to do his lessons while his father came up and advised him to take a break. Soon they came up a good idea. They decided to go cycling in the countryside. Li Ming enjoyed himself competing and chatting with his father and felt relaxing in the open air. On Monday, Li Ming was energetic and active in class. He spent a whole day in the country, and Li Ming said what he had done was worth.
