问题                Eye Movement and Several Faults in Reading
    Suppose you do this experiment with a friend. Get hold of a book with a large page size and lines that run right across the page. Get your friend to hold the book up and to read it with the top of the book just below his eye level. This means that you can watch the movement of his eyes as he reads the page. If you do this, you will see that your friend’s eyes do not make a continuous forward sweep. Instead, they progress by little "jumps" moving, then stopping, as they progress along the line. This kind of jumping movement is called a saccadic movement(跳跃).
    There has to he this starting and stopping movement because the eye can see only when it is still motionless. Every time the eye pauses 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. If you record the eye movements of someone who is reading, you will notice that, from time to time, the reader goes back and looks again at something he has read before; in other words, he regresses(回视) an earlier part of the text, probably because he realizes he does not understand the passage properly. Then he comes back to where he left off and continues reading. At one time, it was though that regression was a fault, but it is in fact a very necessary activity in efficient reading.
    There are several different kinds of faults in reading, which are usually more exaggerated with foreign language learners. The most common one is that most people read everything at the same slow speed, and do not seem to realize that they can read faster or slower as required. Other people say the words to themselves, or move their lips-these habits slow the reader down to something near speaking speed, which is of course much slower than reading speed. Another habit that can slow you down is following the line with your finger, or with a pen.
Why do people’s eyes read by little "jumps"?
选项 A、Because they can read at a greater speed in this way.
B、Because people’s eyes cannot see unless they are motionless.
C、Because it is easy to get to tried otherwise.
D、Because people’s eyes progress in a saccadic movement while reading.
答案B
解析 本题考查考生正确理解原文细节的能力。考的是在阅读时人眼为什么要跳跃。文章第二段开头提到：There has to be this starting and stopping movement because the eye can see only when it is still…即告诉读者：人眼这种移动方式原因在于它只有在静止时才能看得见。因此，A、C项所说的这样能以更快的速度阅读，或这样不太容易疲劳，都不是本题的正确答案。D项说到因为人眼在阅读时是以一种跳跃的方式移动，这不过是题干的另一种表达，与题干不构成因果关系，所以不能选。B项说，人眼除非静止，否则是看不见的，与文章所表达的意思是一致的。所以，正确答案是B。
