7、Possible version:

As we all know, communication has been playing an important part in people’s life. As can be seen in the pictures, there are three ways of communication, of which I like communication by computer most. My reasons are as follows.

  Firstly, by computer, people can easily send emails to each other at any time and at any place, while it is too slow a way to communicate by writing letters. Moreover, it is easy to lose letters. Secondly, by computer, people can chat to each other face to face, while it is difficult for us to do so on the phone. Finally, surfing on the Internet can provide people varieties of information, which is very convenient and useful to our study as well as to our life. It is really a good way to broaden our horizons and improve people’s understanding of the world.

In a word, communication on the Internet helps bring people all over the world closer.
