The telephone. Humans do not live on their own. We need communication in all aspects. The invention of the telephone definitely changed our life as it shortened the distance between us. And no matter how far you live, you can still receive a love message. How sweet!

Fans keep you cool even when there's no breeze at all. Moreover, they give you a natural feeling but not like 'frozen meat' in the fridge when you have the air-con on.

Words are the greatest invention of all. Words are what distinguish us from animals. And words are crucial to the development of society. Without records of our ancestors' knowledge, the development of technology and culture of mankind would certainly be hindered.

For me, it must be the telephone. Why? It has made great progress in communication since it was invented by Alexander Graham Bell in 1876. What's more, it does not cause any harm to the environment. It is very convenient too.

The mobile phone. It relates us to different people. We can talk to friends whenever we want though they are far away. Also, it eases our life, for example, we use it to book services. Moreover, when we're in danger, we can use it to seek help.
