18．Do you know that a fast reader can get the ideas better than a slow reader can？Of course，you save time by reading fast，but this is not the main reason for fast reading．The main reason is that you understand better what you are reading when you read fast．
As your eyes move along the line of point，they make fixations （固定） or pauses （暂停）．It is important that you see several words at a fixation．It is also important that your eyes leave a group．The numbers of letters or words that you see at a fixation are called your eye span （视跨）．Pay more attention to improving your rate of reading．With practice you can learn to read faster than you usually read．
