    How to use speed reading to go through newspapers or magazines? 小题1: You will not only save time, but also your focus will increase and you will have fun reading even the  uninteresting reports.
     小题2: This plays to the advantage of the tired reader who wants to stay current but has very little time to read. Often all you need to understand a news piece is the first paragraph. Here the reporter will tell you what’s happening, who it’s happening to and where it’s happening.
    Sometimes you don’t even need to read the entire paragraph because the first sentence or the first couple of sentences give you all the information. If you still have more time you can move on to step two.   小题3:Read the last paragraph. Some news pieces are follow-ups of events that were earlier reported. In such a situation, the first paragraph may not give you all the information you need.  小题4: It’s usually in the last paragraph that the user is given the background information that leads to the story.
    Read the “quotes” after you’ve read the first and last paragraphs and you still feel you need more information or have more time to play with, you can come into middle of the piece by reading the direct speech of the sources of the news item. In all forms of writing where quotations are used, the writer leads the reader into the quotes and then leads the reader out. This takes too much space and therefore, robs the reader out of some precious time.
      小题5: 
    A.Read the first paragraph.
    B.But the last paragraph will do the job.
    C.The first paragraph may be not important at all.
    D.Otherwise, you can stop reading.
    E. Here are three techniques you can use.
    F. So glide directly to the quotation marks and read what’s within them.
    G. If you follow these steps, it’ s possible to get about 80 percent of a news piece.
