Presentation An Entry from Li You’s Diary November 3, Tuesday I was very busy and tired today. I got up at seven-thirty this morning. After taking a shower, I had breakfast. While I was eating, I listened to the sound recording. I went to the classroom at nine o’clock. The first period was Chinese. The teacher taught us pronunciation, new vocabulary, and grammar. The teacher also taught us how to write Chinese characters, and gave us a new text. The text was very interesting. The second period was Computer Science. It was very difficult. At noon I went to the cafeteria with my classmates for lunch. While we were eating, we practiced speaking Chinese. In the afternoon I went to the library to go online. At four o’clock, Wang Peng came looking for me to play ball. I had dinner at a quarter to six. At seven-thirty, I went to Bai Ying’ai’s dorm for a chat. When I got there, she was doing her homework. I got home at eight-thirty. Before I went to bed, Gao Wenzhong called. He told me there’d be an exam tomorrow. I said I already knew that.
