A child whose habits have been disciplined and who has been taught to rise early, attend to his lessons properly, take physical exercise at the proper time and avoid things that are injurious, will grow up to be a useful member of the society. The spoilt child who has been allowed to run his own course will show vice contacted in younger days. His parents would wish that he had not been born at all.

11 Q.2 Read the following passage carefully and answer the questions given below: It was a rare occasion for ten students of this school to participate in the National Exhibition on Environmental Protection held at IIT, Powai, Mumbai, about two hundred students from various parts of India took part in it, many voluntary organizations and distinguished environmentalists also participated in it. The Hon ble Chief Minister inaugurated the exhibition. The leading themes of the exhibition were the protection of our forest wealth, keeping our lakes and rivers pollution free, the hazards of air and sound pollution. The biggest draw of the exhibition was the section on the Himalayas. The exhibition evoked a spontaneous response among the local people, especially, the students. Such exhibitions are necessary to educate the people regarding environmental pollution. Large scale deforestation, haphazard urbanization and industrialization, have converted green belts into jungles of concrete. Environment pollution, smoke and dirt have turned cities like Delhi into gas chambers. The people can learn the value of growing more trees and the dangers of deforestation. Our rivers, lakes and streams have become the damping pools of the industrial waste. Green belts are disappearing fast. Unplanned urbanization has brought only degradation of the environment. It is certain that the National Exhibition will go a long way in educating the people and highlighting the need for preserving our environment to them.
