Sustained Silent Reading（SSR）is the practice of providing a short period of class time for students to read silently whatever they choose according to their interests.SSR programs can be offered at actually any grade level.However，it takes a great deal of time，effort，and know-how to put a successful SSR program into operation.I first recognized this when I was a high school teacher twenty years ago.Though some of my students were happy to be allowed to select and read books in class，many never truly dived into their reading.I knew that there must be ways to improve the implementation（實(shí)施） of my SSR program，but I wasn't sure what they were.
   Years later，when I returned to the University of Southern California，I began analyzing a large sample of SSR studies to determine what made them effective and found that successful programs shared five key factors：easy access to reading materials，sufficiently interesting materials，teachers' encouragement，follow-up activities and reading at least twice a week.
   In fact，only when teachers follow specific guidelines do these programs achieve their full potential.Having learned this，I decided to create an "ideal" SSR program for my students by employing the five factors above.At the same time，another high school in our district also made the decision to offer students SSR time each day.However，having no knowledge of the five factors，the teachers simply asked their students to "read anything for fifteen minutes."
   The result was that the students at my school outperformed（勝過(guò)）the other school in four areas：reading comprehension，positive attitudes toward reading，frequency of after-school pleasure reading，and use of a wider range of reading sources.I shared my findings with the other school's staff members.Since then，both schools have experienced the positive benefits of SSR.
   Today，I have given many lectures at a wide variety of schools where teachers are eager to learn "how-to" methods for developing programs that will motivate their students to become hooked on reading.They ask a variety of excellent questions and I have never been bored of answering them.
