【正确答案】Inventions have changed our life greatly. For example, computer improves our working efficiency, microwave makes cooking easier, television enriches our leisure time, and telephone simplifies communication. Among various inventions, e-mail is the most important invention in my eyes for it has revolutionized communication.
Firstly, such an innovation makes people closer in spatial, temporal and emotional dimensions. In the past, it's nearly impossible for people to communicate with others in distant area so conveniently. Letter is too slow, and telephone is too costly. With e-mail no matter where your friends are, you can keep in touch with each other frequently, which not only saves time and money, but more importantly, makes emotional exchange much easier. Secondly, such an invention makes communication more efficient. One piece of message can be sent to hundreds o{ others at the same time, so that many people can share the same thing simultaneously, which saves troubles of coping and sending many times. Thirdly, e-mail revolutionized communication also in that much and varied information can be conveyed by e-mail—letters, documents, video and audio files—to meet people's various needs.

So it has become a good companion, a generous helper, and a close friend. To wind up my discussion, I want to restate my view: e-mail is the most important invention in my eyes.
