A Letter from a Parent to a Teacher
He will have to learn, I know, that all men are not just, all men are not true. But teach him also that for every scoundrel there is a hero, that for every selfish politician, there is a dedicated leader. Teach him that for every enemy there is a friend. Teach him that a dollar earned is of far more value than five found. Teach him to learn to lose and also enjoy winning. Steer him away from envy, if you can. Teach him the secret of quiet laughter. Teach him the wonder of books, but also give him quiet time to ponder over the eternal mystery of birds in the sky, bees in the sun and flowers on a green hillside. In school, teach him it is far more honourable to fail than to cheat. Teach him to have faith in his own ideas, even if everyone tells him they are wrong. Teach him to be gentle with gentle people and tough with the tough. Try to give him the strength not to follow the crowd when everyone is getting on to the bandwagon. Teach him to listen to all men, but teach him also to filter all he hears on a screen of truth and take only the good that comes through. Teach him to close his ears to a howling mob; and to stand and fight if he thinks he’s right. Treat him gently but do not cuddle him, because only the test of fire makes fine steel. Let him have courage to be impatient, let him have the patience to be brave. Teach him always to have sublime faith in his creator and faith in himself too, because then he will always have faith in mankind. This is a tall order but please see what you can do. He is such a fine little fellow, my son!

Power Saving
We know that electricity is generated in power plants:
- Hydroelectric Power Stations – They are at dams where water is used to generate electricity.
- Thermal Power Stations – They use coal to generate electricity.
- Nuclear Power Stations – They use radioactive metals to generate electricity.
Saving water is in some or the other way related to producing and saving electricity. We should know the worth of it.
Write a paragraph on “Saving Electricity.” Here are some clues for you:
- Switch off lights
- Power saving lamps and devices
- Work during day time
- Unnecessary electric decoration
- Well ventilated and lighted houses
- Unnecessary use of electrical appliances
- Automatic electric iron
- Television and radio is on though nobody is watching or listening to it.
Electricity is an essential resource, and saving it is crucial for a sustainable future. We can conserve electricity by adopting simple yet effective measures. For instance, switching off lights and electrical appliances when not in use is an important step. Using power-saving lamps and devices, such as LED bulbs, can reduce energy consumption. It is also advisable to work during the daytime to minimize the use of artificial lighting. Avoiding unnecessary electric decoration and ensuring houses are well-ventilated and naturally lit can further save electricity. Reducing the unnecessary use of electrical appliances, such as keeping televisions and radios off when not being watched or listened to, also makes a difference. Automatic electric irons should be used to ensure efficient energy use. By practicing these methods, we can contribute to saving electricity and ensuring its availability for future generations.
