5．The tall man was sitting in the chair．He was reading a book．When I talked to him，I found that from boyhood （少年時(shí)代），he had the habit （習(xí)慣） of carrying a little book in his pocket．He often read every minute when he was not doing anything else．He found a book very useful during the time of waiting，such as waiting for meals，buses，doctors，telephone calls，plays to begin or something to happen．That was how he found his fifteen minutes a day for reading．
That was how he read his twenty books a year--one thousand in his lifetime．
