摘要:This paper studies and suggests the need for writing instruction by which students can experience writing as a creative process in exploring and communicating meaning. The prewriting activities generate ideas which can encourage a free flow of thoughts and help students discover both what they want to say and how to say it on paper. Through the activation of the formal schema, students can understand how to organize the material according to the requirements of the writing task and the general structure of the English composition. The authors choose a writing task in College English as an example to show the teaching procedure in the prewriting process. Through the instruction of the writing task on an argumentation, the authors summarize the essential steps of the teaching of English prewriting activities.
