EFL Fluency Development and Its Effects

Some people read fast others read slower and we tend to read less fast in a foreign language than in our native language. Can people be trained to read faster? Will this affect their comprehension? Some people say we understand less when we read faster especially when we read in a foreign language. Is it true that if EFL learners are trained to read faster their comprehension decreases? Also if our silent reading rate improves will our oral reading rate increase too? This book gives the answers to these questions.
