寫作思路：首先把自己難忘的人介紹出來，然後說明難忘他的理由。
When I was in high school, one of my classmates sit right beside me. His name is ChenLiang. He is my unforgettable person in my life.I remembered my mathematics was just mediocre at that time, but he was extraordinary and excellent in calculating and solving mathematic questions. He often received perfect scores.?
當我在高中的時候，我的壹個同學坐在我旁邊。他的名字是亮。他是我壹生中最難忘的人，我記得當時我的數學成績很平庸，但他在計算和解決數學問題方面表現不凡，成績優異。他經常得到完美的成績。
Of course, I wished I could reach at his level. Since we talked all day long, I asked how he could solve those difficult questions. He was so patient and polite to answer my sometimes ridiculous thinking. Gradually, I built my confidence at mathematics and finally passed the college entrance exam.
當然，我希望我能達到他的水平。既然我們談了壹整天，我問他怎麽能解決這些困難的問題。他是那麽耐心和禮貌的回答我有時可笑的想法。漸漸地，我對數學有了信心，並最終通過了大學入學。
Now, we are apart, but I still remember his great attitude and willing in study. I am so obliged to my classmate, who is my friend always and forever.
現在，我們分開了，但我仍然記得他的偉大的態度，並願意在學習。我很感激我的同學，他是我的朋友，永遠和永遠。
