听力原文： In the United States today, books with suggestions on how to do things are very popular. There are about four to five thousand books with titles that begin with the words "How to". One book may tell you how to earn more money, another may tell you how to save or spend it, and another may explain how to give your money away.

Some "how to" books tell you how to choose a job and how to succeed at it. If you fail, however, you can get a book called How to Turn Failure into Success. If you would like to become very rich, you can buy How to Make a Million. If you never make any money at all, you may need a book called Horn to Live on Nothing.

One of the meat popular types of books is one that helps people with their personal problems. If you are unhappy with your life, you can read Haw to Love Every Minute of Your Life. If you are tired of books on happiness, you may prefer a book called How to Make Yourself into Trouble. There is even a book about how to take your own life.
