8. A piece of equipment----airconditioner

　　I’d like to talk about a piece of advanced equipment in my home, an air

　　conditioner. My parents bought it in a department store when I was sixteen years

　　old to replace the old one.

　　I think it is interesting to use this equipment, just like magic. Because

　　when we use it, it can change hot air to cold air. When we are cold, we also get

　　warm by using it. I can’t imagine what our life will be if we don’t have it.

　　Of course we don’t use it all the time. Because when in spring or autumn,

　　the weather is very comfortable, it isn’t necessary to use it. If we use it all

　　the time, it is not environmental friendly. Also, it is not good for our health

　　if we stay in an air-conditioned room for a long time. When I feel very hot or

　　cold outside, I will miss my air conditioner.
