(Para.1) Surfing on the Internet is no longer something strange. To some extent, it is becoming part of our daily life. We can do a lot of things online, such as searching for information and communicating with friends no matter how far. But recently another useful online service has become very popular. That is online education, which is also called distance education. It helps students who take classes by computer over the Internet to learn certain courses and earn a degree. (Para. 2b) students communicate with each other and their teachers. Some classes may require students to all log in at the same time so they can attend live lectures by a professor. Third, the Internet is informative. The information it stores in the lately 20 years is more than what human being has recorded in the past 2000 years. It is just like a 24hour library, which enables us to search for the right information we need by simply typing in some key words. (Para. 3) This new form of education is indeed more successful than the traditional education. It can provide different learners with more flexible and versatile ways of learning, and at the same time allows some learners to stick to their present jobs while studying the latest knowledge online.
