University Life is so good.Every day of ocean travel in
the book.Always forget to take it out on time forbooks.Each had to pay an extension fee.Also affected the otherstudents read.Out of my mind think of this idea.We can reflect abookmark for the book.Time display library by date, due date, the remaining number of days.Play a regulatory role in their own reading time.Seize the moment of his time to reflect.
