Angelo's Favourite Invention (Shoes)

Shoe is the piece of clothing that aims to protect the feet. Today, this piece serves as adornment and fashion accessory, and also a social function.
In the XIX century begun to emerge machines to help the confection of shoes, but with the sewing machine are more facilitated and accessible.
In the XX century surge changes in this industry, the leather was exchanged by synthetic materials.

I choose the shoes because all people in the world had ones.

The importance of technology

In our opinion the technology is very important to the progress of the world. In the past there weren't computers, mobile phones, ipods and other technological gadgets, so the people had other forms to communicate, do research work, have entertainment and do other activities.
The technology in the school is very important to the progress of the teenagers, because the access and the organisation of the imformation are easier and developed. The teenagers in the past didn't have these technologies and they had ton get other forms to research information.
