Photos that you might have found down the back of your sofa are now big business! In 2005, the American artist Richard Prince's photograph of a photograph, Untitled (Cowboy), was sold for $ 1, 248, 000. Prince is certainly not the only contemporary artist to have worked with so-called "found photographs"--a loose term given to everything from discarded prints discovered in a junk shop to old advertisements or amateur photographs from a stranger's family album. The German artist Joachim Schmid, who believes "basically everything is worth looking at", has gathered discarded photographs, postcards and newspaper images since 1982. In his on-going project, Archiv, he groups photographs of family life according to themes: people with dogs; teams; new cars; dinner with the family; and so on. Like Schmid, the editors of several self-published art magazines also champion found photographs. One of _ , called simply Found, was born one snowy night in Chicago, when Davy Rothbard returned to his car to find under his wiper an angry note intended for some else: "Why's your car HERE at HER place?" The note became the starting point for Rothbard's addictive publication, which features found photographs sent in by readers, such a poster discovered in our drawer. The whole found-photograph phenomenon has raised some questions. Perhaps one of the most difficult is: can these images really be considered as art? And if so, whose art? Yet found photographs produced by artists, such Richard Prince, may riding his horse hurriedly to meet someone? Or how did Prince create this photograph? It's anyone's guess. In addition, as we imagine the back-story to the people in the found photographs artists, like Schmid, have collated , we also turn toward our own photographic albums. Why is memory so important to us? Why do we all seek to freeze in time the faces of our children, our parents, our lovers, and ourselves? Will they mean anything to anyone after we've gone? In the absence of established facts, the vast collections of found... According to the passage, Joachim Schmid _ . A) is fond of collecting family life photographs B) found a complaining not under his car wiper C) is working for several self-published magazines D) wondered at the artistic nature of found photographs

The effects of air pollution on natural conditions have been a disturbing problem for many years. Some scientists hold the view that the air inside houses may be more dangerous than the air outside. It may even be one hundred times worse. Most scientists agree that every modern house has some kind of indoor pollution, which can cause a person to feel tired, to suffer eye pain, headache and other problems. Believe it or not, some pollutants can cause breathing diseases of blood and even cancer. What made us feel relieved is that there's growing concern about the problem now. It is true that when builders began constructing houses and offices they did not want to waste energy. they built buildings that prevented or limited the flow of air between inside and outside. For the same purpose, man-made building materials were employed to build houses, which are now known to let out some harmful gases. Facing the serious challenge, scientists have been searching for a way to handle the problem. To everyone's delight, they discovered a natural pollution control system for building--green plants, though they do not really know how plants control air pollution. Scientists suppose that a plant's leaves absorb or take in the pollutants and in exchange gives out oxygen through its leaves and tiny organizations on its roots. Therefore they recommend that all buildings should have one large plant or several small plants inside for every nine square meters of space. Because studies indicate that different plants absorb different chemicals, the most effective way to clean the air is to use different kinds of plants. In conclusion, having green plants inside your house can make it a prettier and healthier place. Why not try? The reason why we should use different kinds of plants to clean the air is that _ . A) plants can drive out all kinds of pollutants indoors B) plants can absorb different harmful indoor chemical C) plants can take in all pollutants inside and outside D) plants may give out more oxygen than people need

When my mother was alive, she used to tell me again and again about the value of just being nice. "Never underestimate the power of a smile," she would say. I fear she would be very disappointed looking at the world today. A lot of people don't smile and when it comes to service today, they're just not nice. Now don't give me wrong, not all service workers but a good many. I was on the phone the other day with a computer help desk. First a man, then later a woman, who couldn't have been ruder. And this to a customer, who didn't know his way around a PC. But no matter, I could tell they thought I was a bother, The woman, in fact, seemed to be chewing gum as she unemotionally clicked off a series of commands for me to perform. The next day I heard from a friend of mine who got a performance review without his boss once looking up at him. Not once. You see it everywhere. Gone are the days when people cared about you. It's a sign of the time, I suspect. But that makes me sad -- for them and for us all. People who aren't happy, who don't smile, who don't kid, who don't joke or make light of even bad situations, make for an even worse situation. And it spreads like a cancer. Someone's rude to you, you're rude to them and to the next fellow you meet, and on and on. Smiles are contagious but so annoyances. The boss who can't be bothered with his workers. The celebrity who can't be bothered with her annoying fans. You know, my mom used to judge presidential candidates by how they smiled. I would say, "But mom, you don't know if that smile is real." "Oh, yes I do," she would tell me. "I can feel it." It's in their eyes, she would say. And it's in their smile. The rest just kind of falls into place. Why did the writer mention his phone call? A) To prove his mother is wrong. B) To show many people aren't nice. C) To tell us he knows little about computer. D) To share his funny experience with us.
