Article: The Process of Ageing At the age of twelve years, the human body is at its most vigorous. It has yet to reach its full size and strength, and its owner his or her full intelligence; but at this age the possibility of death is least. Earlier, we were infants and young children, and consequently more vulnerable ; later, we shall undergo a progressive loss of our vigour and resistance which, though vague at first, will finally become so steep that we can live no longer, however well we look after ourselves, and however well society, and our doctors, look after us. This decline in vigour with the passing of time is called ageing. It is one of the most unpleasant discoveries which we all make that we must decline in this way, that if we escape wars, accidents and disease we shall eventually "die of old age", and that this happens at a rate which differs little from person to person, so that there are heavy odds in favor of our dying between the ages of sixty-five and eighty. Some of us will die sooner, a few will live longer -- on into a ninth or tenth decade. But the chances are against it, and there is a virtual limit on how long we can hope to remain alive, however lucky and physically strong we are. Normal people tend to forget this process unless and until they are reminded of it. We are so familiar with the fact that man ages, that people have for years assumed that the process of losing vigour with time, of becoming more likely to die the older we get, was something self-evident, like the cooling of a hot kettle or the wearing-out of a pair of shoes. They have also assumed that all animals, and probably other organisms such as trees, or even the universe itself, must in the nature of things "wear out". Most animals we commonly observe do in fact age as we do, if given the chance to live long enough; and mechanical systems like a wound watch, or the sun, do in fact ran out of energy in accordance with the second law of thermodynamics . But these are not similar or equivalent to what happens when man... Question: What can be learned from this passage is that _ . Yes or no, is the answer "people usually are unhappy when they are reminded of ageing"?
Yes

Article: Each morning Grandpa was up early sitting at the kitchen table, reading his book. His grandson wanted to be just like him and tried to copy him in every way he could. One day the grandson asked, "Grandpa, I try to read the book just like you, but I don't understand it, and I forget what I understand as soon as I close the book. What good does reading the book do?" The grandpa quietly turned from putting coal in the stove and replied, "Take this coal basket down to the river and bring me back a basket of water." The boy did as he was told, but all the water leaked out before he got back to the house. The grandpa laughed and said, "You'll have to move a little faster next time," and sent him back to the river with the basket to try again. This time the boy ran faster, but again the basket was empty before he returned. Out of breath, he told his grandpa that it was impossible to carry water in a basket, so he went to get a bucket instead. The grandpa said, "I don't want a bucket of water; I want a basket of water. You're just not trying hard enough." The boy again dipped the basket into the river and ran hard, but when he reached his grandpa the basket was empty again. Out of breath, he said, "Grandpa, it's useless!" "So, you think it is useless?" the grandpa said, "Look at the basket." The boy looked at the basket and for the first time he realized that the basket was different. It had been transformed from a dirty old coal basket and was now clean. "Grandson, that's what happens when you read the book. You might not understand or remember everything, but when you read it, you'll be changed, inside and out." Question: What puzzled the grandson most was _ . Yes or no, is the answer "whether it was useful to read books"?
No

Article: Famous centenarians still active in arts, science are in no mood to retire."Those who stand still, die," is one of Oliveira's favorite phrases.He knows from experience what it means, as the Portuguese film director has reached the age of 102 and is still active in his profession.Every year, Oliveira shoots a film and is currently working on his next project."You have to work, work, work in order to forget that death is not far away," he said.When asked about his age, Oliveira said with some humility: "It's down to mother nature.It gave to me what it took from others." Being both mentally and physically fit in old age is partly a matter of luck, but it also has something to do with character.Not every white-haired person is wise and social skills, openness and the ability to train the brain are essential for senior citizens. Along with the architect Oscar Niemeyer (103), Nobel laureate Montalcini (101) and director Kurt Maetzig (100), Oliveira is one of those people of whom it would be very wrong to think as members of a listless elderly generation. Another master in his profession is the architect Oscar Niemeyer.The 103-year-old Brazilian is best known for his futuristic-looking buildings in Brasilia, but he also speaks out on behalf of the poor."The role of the architect is to struggle for a better world where we can develop a form of architecture that serves everyone and not just a privileged few," said Niemeyer recently.He spends almost every day working in his office in Copacabana, and even when he falls ill he keeps working on ideas: After a gallbladder operation he composed a samba tune in the clinic. Another man who could sing a song about age is 107-year-old Heesters.The Dutch-born opera singer spent most of his life performing in Germany, where he still works.Recently Heesters said: "I want to be at least 108-years-old." He also plans to keep performing." _ " Heesters has not given up trying to add to his tally of awards and is looking for a "good stage role". Italian scientist Rita...
