Old people are always saying that the young are not what they were. The same comment is made from generation to generation and it is always true. It has never been truer than it is today. The young are better educated. They have a lot more money to spend and enjoy more freedom. They grow up more quickly and are not so dependent on their parents. They think more for themselves and do not blindly accept the life goals of their elders. Events which the older generation remembers vividly are nothing more than past history. This is as it should be. Every new generation is different from the one before. Today the difference is very noticeable indeed. The old always believe that they know best for the simple reason that they have been around a bit longer. They don't like to feel that their values are being questioned or threatened. And this is exactly what the young are doing. Wouldn't people work best if they were given complete freedom and responsibility? And what about clothing? Who said that all the men in the world should wear dull grey suits and very short haircuts? Who said that human differences can best be solved through normal politics or by violent means? Why have the older generation so often used violence to solve their problems? Why are they so unhappy and guilty in their personal lives, so occupied with mean ambitions and the desire to collect more and more wealth? Haven't the old lost touch with all that is important in life? These are not questions the older generation can shrug off lightly. Their record over the past forty years or so hasn't been exactly spotless. Traditionally, the young have turned to their elders for guidance. Today, the situation might be opposite. The old--if they are prepared to admit it--could learn a thing or two from their children. One of the biggest lessons they could learn is that enjoyment is not wrong. Enjoyment is a principle one could apply to all aspects of life. It is surely not wrong to enjoy your work and enjoy your free time. It is surely not wrong to live in... Which of the following about the young is NOT mentioned in the article? A) Better educated. B) Richer. C) Independent. D) Hard-working

Scientists have devised a way to determine roughly where a person has lived using a strand ( ) of hair, a technique that could help track the movements of criminal suspects or unidentified murder victims. The method relies on measuring how chemical variations in drinking water show up in people's hair. "You're what you eat and drink, and that's recorded in your hair," said Thure Cerling, a geologist at the University of Utah. While U.S. diet is ly identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as rain clouds move. Most hydrogen and oxygen atoms in water are stable, but traces of both elements are also present as heavier isotopes ( ). The heaviest rain falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah. Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds to about two months. Cerling's team collected tap water samples from 600 cities and constructed a map of the regional difference. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops. They were able to accurately place the hair samples in broad region roughly corresponding to the movement of rain systems. "It's not good for pinpointing ( )," Cerling said. "It's good for eliminating many possibilities." Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake. The woman was 5 feet tall. Police recovered 26 bones, a T-shirt and several strands of hair. When Park heard about the research, he gave the hair samples to the researches. Chemical testing showed that over the two years before her death, she moved about every two months. She stayed in the Northwest, although the test could not be more specific than... What is the scientists' new discovery? A) One's hair growth has to do with the amount of water and drink. B) A person's hair may show where they have lived. C) Hair analysis accurately identifies criminal suspects. D) The chemical composition of hair varies from person to person.

It is love that makes the world go round. And it is also love that has such power to overcome all difficulties. So we say: "Love will find a way." As smile is a facial expression showing pleasure, affection, and friendliness, it is the commonest way to show our good will perfectly without saying anything. A Chinese saying runs: "never hit a person who is smiling at you." It is a time-proven fact that the smile is a language all its own-- a universal language--understood by the people of every nation in the world. We may not speak the same tongue as our foreign neighbors, but we smile in the same tongue. We need no interpreter for thus expressing love, happiness, or good will. One day while shopping in a small town in southern California, it was my misfortune to be approached by a clerk whose personality contradicted mine. He seemed most unfriendly and not at all concerned about my intended purchase. I bought nothing, and marched angrily out of the store. My anger toward that grew with each step. Outside, standing at the corner, was a dark-complexion young man in his early twenties. His expressive brown eyes met and held mine, and in the next instant a beautiful, dazzling smile covered his face. I gave in immediately. The magnetic power of that shining smile drove away all bitterness within me, and I found the muscles in my own face happily responding. "Beautiful day, isn't it?" I remarked, in passing. Then, suddenly something inside me sent me turning back. "I really owe you a debt of gratitude," I said softly. His smile deepened, but he made no attempt to answer. A Mexican woman and two men were standing nearby. The woman stepped forward and eyed me inquiringly. "Carlos, he no speak English," she volunteered. "You want I should tell him something?" In that moment I felt transformed. Carlos' smile had made a big person of me. My friendliness and good will toward all mankind stood ten feet tall. "Yes," my reply was enthusiastic and sincere, "tell him I said 'Thank you!'" "Thank you?" The woman seemed slightly... The author got angry while shopping one day because _ . A) of the clerk's unfriendliness and lack of concern B) of her misfortune C) she failed to purchase what she intended D) a dark-complexion young man laughed at her
