This ability to see words on either side of the point at which your eyes focus is called peripheral (周围的) vision. Foreign students of English often feel that it is impossible to recognize so many words at a single glance. It is difficult for many native speakers, but it can be done. It is something that has to be done if you are to read as rapidly as you should. You can increase your peripheral vision by eye exercises.
Equally important is the importance of moving your eyes from point to point in a uniform rhythm (以不变的节奏). Slow reading often results from regression (退回), the number of times your eyes have to go back. While practicing to increase your peripheral vision and uniform rhythm, you may occasionally have to go back to reread. Do not be discouraged. A smooth, forward rhythm comes with practice. Eventually your speed will get to the point where your eyes move comfortably forward without regression.

A. things far away
B. printed matter more clearly
C. a wider range of things
