Last week,I attended a lecture by a teacher in his thirty. He was energetic and confidence. He spoke very fast and I could understand that he said. He mainly focused at how to learn the English well. In addition,he showed us how to write neatly, letter by letter. He kept telling us, “Slow down!” “Trusting yourself!” “Write carefully!”. To be honest, I never thought much of writing until today, when my heart touched. At the end of the lecture, all the people present break into cheers. The lecture was so interesting that I benefited a lot from them.
