What actually happens when we read?Some people think that we read one word    21   ,

understand it and then go on to the next. Other people think that our eyes smoothly   22  over each line from left to right, then back to the beginning of the   23   line, and so on. In fact, the physical action of reading usually doesn’t work in   24   of those ways.

  25   you do this experiment with a friend. Get hold of a book with a large page   26   and with lines that go right   27   the page.   28   your friend to    29   the book up and to read it with the top of the book just   30    his eyes level. This   31   that you can watch the movement of his eyes as he read the page.   32   you do this, you will see that your friend’s eyes do not make a continuous forward sweep.   33   they progress(前移) by little “jumps”, moving,then stopping,as they progress along the line.

  34   to be this starting and stopping movement   35   the eye can see only when it is not moving. Every time the eye   36   it sees a phrase or even a sentence, then jumps to the next part of the line,and so on.

There is another interesting fact about eye movement. You will notice that,   37  , the reader goes back and looks again at something he   38   before, in other words,he returns to an earlier part of the text probably because he   39  he is not understanding it properly. Then he comes back to   40   he stopped and continues reading.
