This morning I went to ask for my English teacher to give me some advice on why to learn English well on the weekend. When I arrived his office at 8 o’clock, he had already done her work for almost one hour. First, we should make a plan of study and carry them out until we succeed. Then, we must master any basic knowledge of English such as 26 letters and 48 sounds. Vocabulary is bricks and grammar is bones. We can make different kinds of phrases and sentences with them according the rules. Finally, practice make perfect. When I leave, it was 12 o’clock. Through this lesson, I learned something which couldn’t be learned from textbooks.
