My father had brought me to this spot in a small Italian towen not far from our home in Rome. I wondered what.
\u201dLook down, Elsa,\u201d father said. I gathered all My idea and looked down. I saw the square in the centre of the village. Then I saw the crisscross of twisting turning streets leading to the square. \u201dSee, my dear,\u201dfather said gently. \u201dThere is more than one way to the square. Life is like that . If you can't get to the place where you want to go by one road, try others.\u201d
In the year that followed, Ioften remember the lesson father sent me .I knew what I wanted to go in my life. I wanted to be a fashion designer. And on the way to my frist small success I found that road blocked. What could I do? Accept the road blocked and fail? Or use imagination and wait to find another road to my goal?
Central Park is a large public, urban park (843 acres or 3.41 km�0�5; a rectangle 2.5 statute miles by 0.5 statute mile, or 4 km \u00d7 800 m) in the borough of Manhattan in New York City. With about twenty-five million visitors annually, Central Park is the most visited city park in the United States, and its appearance in many movies and television shows has made it among the most famous city parks in the world. It is run by the Central Park Conservancy, a private, not-for-profit organization that manages the park under a contract with the New York City Department of Parks and Recreation.
Central Park is bordered on the north by West 110th Street, on the west by Central Park West, on the south by West 59th Street, and on the east by Fifth Avenue. Along the park's borders, these streets are usually referred to as Central Park North, Central Park West, and Central Park South, respectively. (Fifth Avenue retains its name along the eastern border.)
The park was designed by Frederick Law Olmsted and Calvert Vaux, both of whom later created Brooklyn's Prospect Park. It has been a National Historic Landmark since 1963. While much of the park looks natural, it is in fact almost entirely landscaped and contains several artificial lakes, extensive walking tracks, two ice-skating rinks, a wildlife sanctuary, and grassy areas used for various sporting pursuits, as well as playgrounds for children. The park is a popular oasis for migrating birds, and thus is popular with bird watchers. The 6-mile (10 km) road circling the park is popular with joggers, bicyclists and inline skaters, especially on weekends and in the evenings after 7:00 p.m., when automobile traffic is banned.
The Internet is a giant network of computers located all over the world that communicate with each other.
The Internet is an international collection of computer networks` that all understand a standard system of addresses and commands, connected together through backbone systems. It was started in 1969, when the U.S. Department of Defence established a nationwide network to connect a handful of universities and contractors. The original idea was to increase computing capacity that could be shared by users in many locations and to find out what it would take for computer networks to survive a nuclear war or other disaster by providing multiple path between users. People on the ARPNET (as this nationwide network was originally called) quickly discovered that they could exchange messages and conduct electronic "conferences" with distant colleagues for purposes that had nothing to do with the military industrial complex. If somebody else had something interesting stored on their computer, it was a simple matter to obtain a copy (assuming the owner did not protect it).
Over the years, additional networks joined which added access to more and more computers. The first international connections, to Norway and England, were added in 1973. Today thousands of networks and millions of computers are connected to the Internet. It is growing so quickly that nobody can say exactly how many users "On the Net".
The Internet is the largest repository of information which can provide very very large network

Anyway, even if one wanted to, one couldn't put the clock back to an earlier age. Knowledge and techniques can't just be forgotten. Nor can one prevent further advances in the future. Even if all government money for research were cut off (and the present government is doing its best), the force of competition would still bring about advances in technology. Moreover, one cannot stop inquiring minds from thinking about basic science, whether or not they are paid for it. The only way to prevent further developments would be a global state that suppressed anything new, and human initiative and inventiveness are such that even this wouldn't succeed. All it would do is slow down the rate of change.
