Answer» Answer: Reading is one of the most important skills that a person can learn. Reading stimulates our mind. It is like a work out for our brain. When people get old, their muscles begin to deteriorate. They get weaker and their strength leaves them. Exercise can prevent this loss. The same thing happens to people's brains when they get older. Brain power and speed decline with age. Reading STRENGTHENS our brain and prevents this decline. One can benefit from reading in the near-term too. Reading provides KNOWLEDGE. Knowledge is power. Therefore, reading can make us a more powerful person. We can learn to do new things by reading. Do you want to make some gadget? Do you want to design clothing? Reading can teach you all this and more. But you have to get good at reading, and the only way to get good at something is to practice. Reading expands our vocabulary. Even a 'boring' text can teach us new words. Having a larger vocabulary will help us better express ourselves. We shall be able to speak, WRITE, and think more intelligently. Each time you read, you are exposed to new ideas and perspectives. Reading can change the way that one understands the world. It can give us a broader perspective on things. It can make us worldlier. We can learn how people live in faraway places. We can learn about cultures different from our own. Reading is good for our state of mind. It has a calming effect. It can lower our stress levels and help us relax. It can help us escape from our troubles for a moment and it's a positive escape. So, we should try to SQUEEZE a reading MATERIAL for every drop of knowledge that it contains. . mental training please give answer 3. Find a word from the passage, which means the same as, ‘to increase in extent or size’. |
