纯正英语一分钟-Internet（在线收听）

I think the Internet is the greatest invention ever. Think how it has changed the world. So much information is out there. It has totally changed my life. I can chat with friends, download music, buy books and get all the info I need for my homework. It took days or weeks to do any of these things before the Internet. I spend hours every day online. I think I spend a little too long. I’m sure staring at a computer screen all day isn’t good for my eyes. I think it’s also making me fat. I need to exercise a little more. The only thing I don’t like about the Internet is that it can be dangerous. I don’t really like putting my personal information online, especially on social networking sites like Facebook.
