英语翻译
Scanning is a search for information which is of some special interest.A student has first to know the arrangement for information before he can start his search efficiently.Much of the reference material is arranged alphabetically .A dictionary,an encyclopedia,an index of a book,or telephone directory is usually arranged alphabetically for easy quick location of information.But not all material is arranged this way.TV programs,for example,are listed by day and time.Historical data and tables may be listed by month and year.And the sports pages of the newspaper are arranged by category:baseball,football,tennis,and so on.
Whatever the source of reference,it is arranged in some logical way.To prepare for scanning therefore,you should take a minute or two to discover the organization of the material.As soon as you are familiar with the arrangement of information,you can proceed immediately to find the part most likely to contain the information desired.
英语翻译Scanning is a search for information which is of some sp
scan是扫描的意思.在本文中应该引申为略读
略读即带着某种特定的兴趣(目的)去搜索信息.学生如果希望他搜索(信息)的效率提高的话,首先需要了解信息是如何编排的.很多参考资料是按字母顺序排列的,如字典,百科全书,书的目录以及电话簿等都是按字母排序排列(内容)以方便快速的定位信息.但不是所有资料都是这样排列(信息)的.例如电视节目,是按照日期和时间来排列的.历史数据和图标也是这样按年月来排列.另外,报纸上的体育版则是按体育活动分类来排列信息,如棒球,足球,网球等等.
无论是何种参考信息,都会按照一定的逻辑顺序来排列.因此,在准备略读之前,你应该花一两分钟去搞清楚材料的组织方式.当你熟悉了信息的排列方式后,你可以立即找到最有可能包含你要找的内容的章节.
