Research shows a close relation between reading speed and understanding that in most cases an increase in rate was accompanied by an increase in comprehension and a decrease in rate brought decreased comprehension with it. However, simply speeding the rate especially through forced acceleration may actually result in making the real reading problem more severe. The obvious solution, then, is to increase rate as a part of a total endeavor of the whole reading process. Then how? You can prepare for maximum increase in rate establishing practicable habits, such as avoiding rereading and whispering while reading, learning to adjust reading rate to increase comprehension. Rate adjustment may be overall adjustment, or internal adjustment within an article. As an analogy, imagine that you plan to take a 100-mile mountain trip in three hours, averaging about 35 miles an hour. This is your overall rate adjustment. However, in actual driving you may slow down to 15 miles per hour on some curves, while speeding up to 50 miles per hour on relatively straight sections. This is your internal rate adjustment. Poor results are inevitable if the reader attempts to use the same rate for all types of material and for all reading purposes. A good reader adjusts his /her reading rate from article to article, or even within a given article. So you need to foster a good reading habit by daily training until a flexible reading rate becomes second nature to you. 根据材料,判断正误 The passage mainly tells us how to improve our reading speed.
