Acid Rain: Acid Rain , form of air pollution in which airborne acids produced by electric utility plants and other sources fall to Earth in distant regions. The corrosive nature of acid rain causes widespread damage to the environment. The problem begins with the production of sulfur dioxide and nitrogen oxides from the burning of fossil fuels, such as coal, natural gas, and oil, and from certain kinds of manufacturing. Sulfur dioxide and nitrogen oxides react with water and other chemicals in the air to form sulfuric acid, nitric acid, and other pollutants. These acid pollutants reach high into the atmosphere, travel with the wind for hundreds of miles, and eventually return to the ground by way of rain, snow, or fog, and as invisible “dry” forms. Damage from acid rain has been widespread in eastern North America and throughout Europe, and in Japan, China, and Southeast Asia. Acid rain leaches nutrients from soils, slows the growth of trees, and makes lakes uninhabitable for fish ...

MONEY IS BETTER THAN EDUCATION Wealth gives you a much broader range of choices than being poor does. It opens many doors for you that would otherwise be closed. It also gives you power - power to help change the world for the better, or if you prefer, power to topple a government. It gives you a louder voice in the public arena, and so on. Arguments in Favor: Everything in modern society is based on money. As the saying goes, money makes the world go around. Parents object to their daughters' marriages unless their future sons-in-laws have jobs with good prospects. Many young people marry for money rather than love. Security is more important than happiness. Some people in Shanghai would even trade their self-esteem for money. Materialism influences education, too. Students acquire knowledge not for its own sake, but for a bigger wage. Students choose business courses rather than liberal arts for the sake of earning big money in the future. Very few people want to b...

SCIENCE BOON OR CURSE Today, the mankind is living under the shadow of sudden death. It appears that we have come to the end of our journey. Now we stand on the brink of complete and final destruction. The earth has become a dangerous place. It may explode to pieces at any moment. Man has been living on this earth for thousands of years. It has been giving him everything he needed. Then, why it has become so dangerous. The only thing responsible for this is science and its inventions. Science has brought more fear and danger than hope and comfort. In the beginning, it appeared to be the greatest friend and helper of man. It promised to overcome disease and death. The atom bomb wiped out Hiroshima and Nagasaki. It has broken up the established institutions. What has to accomplish it has not ended poverty. He loved his neighbors’ and respected his elders. It promised to make this earth a paradise, and man an immortal god. Science has developed such terrible weapons of war that in th...

Village life is better than city life because......... The cost of living is very high in the city. Most goods are very expensive. There is no fresh air and pure water. The environment is polluted with dust, smoke, garbage and dioxide gases from factories. Most of the people who live in the city are corrupted. So there are lots of crimes in the city. Many thefts and murders often take place in the city. The city is always busy and noisy. There are a lot of vehicles and people in the road. The streets are dusty and unclean.

They have more friends in the community since it is small. The village people always try to protect their traditional habits and culture. The village...

Story "The Tale of the Three Brothers"  “There were once three brothers who were travelling along a lonely, winding road at twilight. In time, the brothers reached a river too deep to wade through and too dangerous to swim across. However, these brothers were learned in the magical arts, and so they simply waved their wands and made a bridge appear across the treacherous water. They were halfway across when they found their path blocked by a hooded figure. The three brothers as death spoke to them And Death spoke to them. He was angry that he had been cheated out of three new victims, for travellers usually drowned in the river. But Death was cunning. He pretended to congratulate the three brothers upon their magic, and said that each had earned a prize for having been clever enough to evade him. So the oldest brother, who was a combative man, asked for a wand more powerful than any in existence: a wand that must always win duels for its owner, a wand worthy of the wiz...

In less than 100 years, Genghis Khan and his descendants established the largest empire in the world, exceeded only by the British Empire in the 19th century. Through cunning diplomacy, spiritual mission, and brute force, Genghis Khan unified the incompatible Mongols and then set out east and west to swiftly conquer vast parts of Asia. The Mongol army swept down on cities and villages, taking anything as booty or victims. By 1280, Mongol rule stretched from China's Yellow Sea to the Mediterranean Sea, a total of 12 million square miles. Among the descendants of Genghis Khan, the most well-known is his grandson, Kublai Khan, admired for his enlightened rule and famous for his opulent lifestyle. During its brief existence, the Mongol Empire was responsible for an estimated 30 to 40 million deaths, the destruction of several major dynasties, and retarding or altering the development of many other civilizations. Yet, at the same time, Genghis Khan and his descendants increased Europe...

Last Sunday it was very cloudy. I, along with my friends, visited the zoo. As we reached near the main gate of the zoo, we saw a huge crowd. Some were buying entrance tickets, some were gossiping and chatting while others were relaxing under the shady trees. We entered the zoological garden and came across a beautiful lake in which some water -birds — like ducks — were swimming. Looking at the white ducks on the smooth surface of water is a charming delight. As we moved, we came to the enclosure in which, flying birds (fowls) were kept. They ranged from sparrows, eagles and parrots to pigeons of various colours. The birds were chirping. It was an enchanting music. We enjoyed it very much. In the next enclosure, there were lions and leopards, tigers and tigeresses whose roars were deafening. We approached the net. A lion rushed towards us and we were frightened. Their fierce looks were frightening for us. After seeing we came across a garden in which, stags and deer were friskingab...

Once upon a time on the island of Crete , maybe about 1325 BC , there was a king whose name was Minos (in the story; this is only a story). He had living in his palace at Knossos a great architect and inventor named Daedalos. There are stories about Daedalus inventing all kinds of things, but he is especially supposed to have built the great Labyrinth for King Minos to keep the Minotaur in. After Daedalus built the Labyrinth, though, King Minos did not want him to be able to tell its secrets to anybody else, and so he kept Daedalos a prisoner in a tall tower, all alone with only his young son Icarus. Now Daedalus and Icarus did not like being prisoners, and so Daedalus began to think about how they could get away. He watched the birds flying and he thought how free they were, and he decided to make wings for himself and Icarus. Daedalus and Icarus made the wings out of   bird feathers and wax and they tied the wings on to each other. Daedalus warned his son to be careful whe...
