Part 1

• There is a special way of reading and writing for people who cannot see. It is called Braille. It is written on a thick paper by making a row of raised points(dots) with a pointed tool. Braille is read by running the fingers on the raised dots.
  

• Louis Braille belonged to France. One day, when he was three years old, he was playing with his father’s tools. Suddenly, a pointed tool hurt his eyes. He lost his eyesight. He had keen interest in studies. He did not give up. He kept thinking of different ways to read and write. Finally he found a way- reading by touching and feeling. This way of reading later came to be known as the Braille script.
• In this type of a script, a row of raised dots are made on a thick paper. Because these dots are raised they can be read by running the fingers on them. This script is based on six points. The Braille script has undergone many changes these days. This has made reading and writing simpler. Braille can also be written using the computer.

 

In Assam, houses are made almost ten to twelve feet above the ground because of heavily rain. They are made on strong bamboo pillars. The insides of houses are also made of wood.

 

In hilly area, houses are made of stone or wood because of heavily rains and snows as well. And when it is very cold, people sit in the sun.

 

New Delhi is the capital of India. People from villages and towns come to big cities like Delhi in search of work. These people often settle in the city. There are a large number of people living here and the space is less. Many people do not have houses at all. They have to live in slums- and many people do not have that either. People sleep wherever they find place- on the road, on the footpath, at the station… Indeed, shelther is a major problem in big cities.
