【正确答案】Electronic Mail
As a product of high technology, e-mail has been widely used. For instance, it is used in business, academic or government communications. And as a substitute for private letters or for face-to-face talk, it is also used to exchange feelings and convey messages to each other. In the picture, we can see two men sitting in front of their computers, talking about having lunch together.
The wide use of e-mail may be due to its unique advantages. First of all, people who adore e-mail love to say that it's quick and convenient. A response can be shot back within seconds, provided that the intended recipient checks it frequently. And the recipient doesn't even have to be at the other end because the message can simply be left for him or her. In addition, this kind of computerized exchange may create friendship. People who are lazy at writing letters may prefer e-mail. What's more, e-mail is a relatively cheap way to leave a message for someone who is far away.
Despite the advantages of e-mail, it also has some disadvantages, It eliminates face-to-face conversation and makes people feel isolated. And when we are cut off from our co-workers, our sense of community and common purpose withers.
In my opinion, we should be aware that e-mail has both advantages and disadvantages. Therefore, we should make proper use of it instead of failing a victim to it.
