[Q]: Article: Back in old times, people had little knowledge about the universe and nature. Things we now consider to be common sense were mysteries to our ancestors. Over the years, major breakthroughs have been made in science and many phenomena have been explained. But still, there are always questions we can't yet answer, and The Guardian has listed some of them. 1. What makes us human? Just looking at your DNA won't tell you - human DNA is 99 percent _ to that of the chimpanzee and, believe it or not, 50 percent identical to a banana's! A lot of the things we once thought were unique about us - language and tool use, recognizing ourselves in the mirror and so on - have since been seen in other animals. Perhaps it's our culture that makes the difference or maybe our ability to use fire. It's also possible that our capacity for co-operation and our trading skills are what make us unique. 2. Why do we dream? Given the fact that we spend around a third of our lives sleeping, shouldn't we know everything about it? Unfortunately, scientists are still searching for a complete explanation of what happens when we sleep and why we dream. Austrian psychologist Sigmund Freud believed dreams were the expressions of wishes that we can't fulfill in our real lives. Others have wondered whether dreams are just random "noise" coming from a sleeping brain. 3. Could we someday live forever? Apart from accidents, most people die because of diseases that can be treated and aging. And since many diseases, such as diabetes and cancer, are diseases of aging, treating aging itself could be the key to extending our lives. Our knowledge of what causes us to age - and what allows some animals to live longer than others - is expanding rapidly. And though we haven't quite worked out all the details, we've worked out some pieces of the puzzles such as DNA damage and metabolism , which are all leading to the invention of drugs that can slow down the aging process. If we're lucky enough to lengthen our lives, we might even get to see the day when all of these questions are answered.

[Q]: Article: A Festival for the Dead is held once a year in Japan. This festival is a cheerful occasion, for on this day, the dead are said to return to their homes and they are welcomed by the living. As they are expected to be hungry after their long journey, food is laid out for them. Speciallymade lanterns are hung outside each house to help the dead to find their way. All night long, people dance and sing. In the early morning, the food that had been laid out for the dead is thrown into a river or into the sea as it is considered unlucky for anyone living to eat it. In towns that are near the sea, the tiny lanterns which had been hung in the streets the night before, are placed into the water when the festival is over. Thousands of lanterns slowly drift out to sea guiding the dead on their return journey to the other world. This is a moving spectacle(,), for crowds of people stand on the shore watching the lanterns drifting away until they can be seen no more.

[Q]: Article: "It's the best...uhh...What? You don't want it?...,"the inexpertienced young man uttered,his hope dashed. "Again,you disappointed me,Andrew.When are you going to learn? You have to be sure and confident. And think how best to make him part with his money. Apply yourself, Son. All your college education will not help if you don't put your mind to selling. Think on your feet. Use psychology," Andrew spoke with diffidence overwhelmed by his father's criticism. "You've been in this shop for six months and you haven't succeeded in selling a single computer. I tell you what. I'll give you one more chance. I'll give you another three more weeks. If you still can't make one sale, I'll call in your elder brother to replace you. He will also take over the shop when I retire. There. I'll just give you one last chance to prove yourself," said Mr. Whitely, his patience wearing thin. Andrew's heart missed a beat. This time he would have to do it. Do or Die! A sense of urgency gripped him. Somehow he must prove himself to his father. It was now the end of the day and the shop was being closed. The assistant employed by his father, called Mike, chuckled and put his arms round poor Andrew to comfort him," Sort it out yourself. It's gotta come from yourself." he said. The shop was located in a bustling shopping center. Andrew left the shop and walked round the complex aimlessly and by chance entered a large bookstore. He glanced at the books and was about to leave when his eyes caught some interesting titles:' How to increase your confidence,'' The art of communication,''How to sell well'amongst others. The next minute he was out of the store with the shopping bag bugling with books. In his apartment (for he loves separately from his parents and little sister),he settled himself in his easy chair and devoured the contents of the books, one by one. His keen intelligence enabled him to focus the details that matter and pick out the ideas and techniques expounded.In a week his image underwent a transformation. Gone was the stubble that used to give him an untidy image likened to a heroin addict.He was also smartly dressed now. Instead of his usual slurred speech and incoherence ,he spoke with clarity, purpose and forcefulness.He was more convincing and persuasive. Above all, confidence flowed from his being and he seemed to have learned a few tricks of the selling trade. He worked hard at his sales pitch and one day he succeeded in selling a computer. His first sale. He had finally achieved the quota of one sale within the given time frame of three weeks. The job, the shop, was his. He had to thank Mike for it.
