DESIGNS FROM NATURE

In a room at Stanford University, scientists are studying a small animal called a gecko. It can move very quickly up and down a tree and even upside down on ceiling. The scientists are particularly interested in the gecko's feet. They want to use the same design on a metal robot that looks very similar to the gecko. This kind of science is called Biomimetics.

In Canada are studying whale flippers because they move so effectively through water. Also, in Germany, engineers at Mercedes Benz are using the shape of the box fish in one of their new cars because it makes the car faster and more fuel efficient. Biomimetics not only has helped to design our world but promise many more possibilities.

THE DEVELOPMENT OF THE INTERNET

The Internet began as a project in the 1960's. It was based on a new idea about how to send information from one place to another. The system of this project is base on packet switching, this system divides up information into smaller pieces, or packets. The packets are sent over a network and the put back together. If one route are busy, the packets take a different rout. It make the network very fast and reliable.

By the early 1990's, the World Wide Web was in place. By the middle of the 1990's, there was a huge amount of traffic on the web. E-Mail and other forms of communication  over the Web had spread throughout the world.

The impact of the Internet

It is hard to imagine life without the Internet.Before the Internet, publication was expensive.One the Web, publication is not limited by cost or location. Many people consider the Internet to be an important democratic institution because it make information available to anyone with access to a computer connected to the Internet. It allows people to share their ideas, but it also allows people to spread hatred and false information.Many people may think of the Web and the Internet as important tools for democracy, but they also create inequalities in society.

In 2002, a U.S Department of Commerce report noted that there were 2 million new Internet users every month.

PARAPHRASING PARAGRAPH (First one of "DESIGNS FROM NATURE")

Gecko is an amazing animal, it can climb and down a tree, that's way scientists of University of Stanford are analyzing this little animal.They're more interested in the gecko's limbs and apply the same design in their robot. It can walk up walls made of glass or plastic.
