36、tter understand the lecture and more easily choose the most appropriate style of notes for the lecture.By selectively recording key points,one can clearly organize the main idea,as well as all the facts,examples,and supporting information used to develop that idea.Unit 6 Part IIPopular note-taking f

38、f a processquestion and answer The following is an illustration of the column-style format.It helps organize information into two different columns.First,draw a vertical line.The left column should be drawn 1/3 the distance from the left side of the page,and the right column should be 2/3 from the r
39、ight side of the page.Next,label the left column“Main Ideas”,and the right column“Notes”.In this way,the main content is arranged orderly and clearly.Unit 6 Part IIFor example:Unit 6 Part IIMain ideas1.2.3.NotesSupporting detailsl l l l Another popular format is the diagram format.First,draw a circl
40、e in the center of the page.Inside that circle,write the topic of the lecture(e.g.Are earthquakes really on the increase?).Next,draw a line branching out from the center circle.Then write the first section,or main idea,of the lecture(for example,reasons for the increase).Draw more circles branching
41、out from that line containing important details which describe that main idea.A more formal version of this format is the flowchart（流程图流程图）.Unit 6 Part IIUnit 6 Part IIWhy have Earthquakes been increasing?Reasons forthe increase1.2.3.The outline format is another popular choice.To organize notes in
42、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 aspects of the main idea in the order of 1.,2.,3.In this format,use indention（缩进缩进）and listing to ensure that these marks are clearly subordinate（附属附属）id
43、eas.Traditionally,with each additional level,one alternates between numbers and letters(with the former,also between Roman numerals and Arabic numbers),and descends from capital letters to lowercase letters.Unit 6 Part IIFor example:I Earthquakes on the rise?A.Reasons for the increase 1.a.i.ii.iii.b
