E-mail or electronic mail, is considered as the modern communication in the new age. It is carried out in computers all over the world by millions of users. In this invisible world as many people call it, the users can send and receive letters to and from every corner of the earth. They share thoughts with pen pals（笔友）in New Zealand, ask strangers in Bombay（孟买）questions, debate with businessman in Manhattan. All of these are just happening in computers as fast as the travelling of the light, no writing and speaking, no paper and stamps are necessary.
E-mail is a pipeline to thousands of experts on everything; it is a means of meeting people with similar interests or problems. But it is not a live talk－a real conversation like those in telephones. E-mailers compose letters at leisure on their computers, then send them by phone line to an on-line service, and then they go forward to the right place. A response can be back within hours, depending on how often the recipient（接受者）checks in.
A vast global networks of on-line services for E-mail has been built. A lot of people are regularly using this service in the USA. People believe that E-mail, the computerized exchange, would create friendship and business developments, and would change people's life in the world.

"The price of books for our students is just getting higher and higher, and along with the rising cost of tuition（学费）, it's killing these students," said Peter Jason, a college professor. "Remember, students are one of the poorest groups of people in America. Almost half of them have at least one part-time job. In fact, one of my students has three jobs. And she still manages to have high scores and go to school full-time."
Textbook prices are usually high. Adding to that problem, many college teachers change textbooks year after year. They either upgrade to a new edition（版本）or change to a different textbook. This further hurts students because if a teacher no longer uses a textbook, that book has no resale value.
Dr. Jason decided to make life a little easier and a lot cheaper for his students by writing his own book on public speaking. "Many books have an increased price because of CD-ROMs, lots of color photographs and pictures. I talked to my students, and many of them, like me, prefer to keep things simple. So, a few years ago, I wrote my own textbook. I made sure that it was simple. Compared to most of other public speaking books, mine is half the number of pages, and one-third the price. That is $30 instead of $90. When I wrote a second edition last year, students only had to buy the 35 new pages. For only $7, they had almost a new book. "
