     Some people have the feeling that nothing can be done about their poor reading ability (能力). They feel

hopeless about it. Can you learn to read better, or must you agree that nothing can be done about it?

     To be sure, people are different. You cannot to do everything as well as certain other people do. It al the

students in a class tried out for basketball, some would be very good players; others would be very poor;

and many would be in between. But even the very poor players can become much better players if they are

guided in the right way, and with plenty of practice. It is the same with reading. Some seem to enjoy reading

and to read well without any special help. Others find reading a slow and tiring job. In between, there are all

degrees of reading ability.

     Many experiments have shown that just about every poor reader can improve his reading ability. In these

experiments, the poor readers were given tests of reading ability. After some of the causes of their poor

reading were discovered, they were given special instruction and practice in reading. After a few months,

another test of the same kind was given. In nearly all cases, these people had raised their reading scores.
