38、e formal version of this format is the flowchart（流程图）.,Unit 6 Part II,Unit 6 Part II,The outline format is another popular choice.To organize notes in this way,first,list the major concepts as the top-level points(I,II,III).Then list the main ideas(A,B,C)as subordinate points.After that,place the as

39、pects of the main idea in the order of 1.,2.,3.In this format,use indention（缩进）and listing to ensure that these marks are clearly subordinate（附属）ideas.Traditionally,with each additional level,one alternates between numbers and letters(with the former,also between Roman numerals and Arabic numbers),a
