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.
