For an everyday and useful invention, I think it is the air- conditioner. I live in Hong kong.
During the summer, the temperature reaches 35 degrees or more. The heat is terrible. Without air
-conditioner, people here cannot work or study. A lot of people will also get sick without cool
air.

I think the most important invention of all time is the mobile phone. It makes us easy to get
information from all over the world. Parents can use the mobile phone to get in touch with their
kids. And we can enjoy the music or films through the mobile phone.
