重复率高不仅是要注意同一个词语总是出现,而且要注意同义的词或者词组。拿TPO1的一篇lecture的一个小片段举一个栗子:OK,I’m going to begin this lecture by giving you yournext assignment.RememberI said that at some point during this semester I wanted youto attend an exhibit at the FerryStreet Gallery and then write about it?Well,the exhibit that I want you to attend is comingup,it’s already started in fact,but it’ll be atthe gallery for the next month,which should give youplenty of time to complete this assignment.在这个片段里总是出现的词有assignment,attend,exhibit,gallery。如果把这些词听出来,连成一个意群"老师布置的一个作业是参加展览,在gallery里"。
