听力原文： Welcome to today's news segment, highlighting business opportunities on the Internet. One such opportunity is a program called Adsense from the major search engine, Google. Basically, Adsense is a simple and easy way for Website owners to place discrete ads on their sites as a means of earning income. You simply insert certain lines of code and then receive a certain percentage of resulting revenue. What is so nice about this program is that it is very simple and straightforward to implement and maintain. Here are some points you should keep in mind. First, the program is free to join. Next, you only have to add a bit of code to each page to display the ads. Also, Google serves up ads on your pages that are relevant to your site's content. These ads can also enhance the content and substance of your own pages. Furthermore, you don't have to deal with advertisers since Google manages the entire pro- gram. Finally, an online log-in area gives you statistics as to the performance of your account. As you can see, the Adsense program can be beneficial to both sides in allowing advertisers to spread the word about their products and services, while Websites who display the ads can earn money to support their own businesses or interests. Visit the Google Website and read the Terms of Service to learn more about this program and see if Adsense is right for you. (33)
