单选题 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 final cause of slow reading is forming the sound of each word, even though you might not speak them aloud. The average American speaks English at 180 to 200 words a minute. If you form the sound of each word, it is impossible to read faster than this. Reading 200 words a minute is a dangerously slow speed.
