5. The Most Effective Way of Communication

a. Animals also have ways of exchanging information. Bees dance and tell each other where to find food. Elephants make sounds that humans can't hear. Whales sing songs, Monkeys use their faces to show anger and love. b. Radio, film and television have had a huge influence on society in the last hundred years. And now we have the Internet which is infinite. But how does this influence us? We can give and get a lot of information

very quickly. But there is so much Information that it is difficult to

know what is Important and what is not Modern media" is changing our

world every moment of every day c. E-mail seems to be replacing other forms of communication for many purposes. As the use of computers has spread, many people use e-mail rather than regular mail to send personal messages.

d. We can communicate with other people in many different ways. We can talk and write, send messages with our face and hands (body language). There is also the phone, the mobile, the fax, the e-mail, the internet, facebook, and skype. Television, film, painting and photography can also communicate ideas.

c. Animal communication is nothing compared to what people can do. We have language -- about 6000 languages, in fact. We can write poetry, tell jokes, make promises, explain, persuade, tell the truth, or tell lies. We have a sense of past and future, not just present.
