Speech on “Prevention Is Better Than Cure”:
(Here is a sample speech based on the lesson’s text)
Good morning everyone. Today I want to talk about the proverb, “Prevention Is Better Than Cure.”
Our lesson on Louis Pasteur shows us how terrible diseases can be. Rabies, for example, causes a deadly inflammation of the brain. When Louis Pasteur was a boy, he saw a man bitten by a mad wolf, and he knew the man would likely die. Measles can lead to pneumonia and diarrhoea, and Rubella can cause blindness or deafness in babies.
Finding a “cure” is incredibly difficult. It took Louis Pasteur many years of experiments on rabbits just to find a treatment for rabies. His first human patient was a huge risk.
“Prevention” is much easier than finding a cure. We can prevent many diseases with simple steps. To prevent malaria, the lesson suggests using repellent and sleeping under a mosquito net. To prevent other illnesses, we should keep our food and water covered. Avoiding animal bites is the best way to prevent rabies.
It is always wiser to take these small, easy steps to prevent an illness than to suffer the disease and hope for a difficult, and sometimes impossible, cure. Thank you.
