Article: For millions of people, the American dream of owning a home seems to be slipping out of reach. "Maybe young couples can no longer afford to buy a ready-made house as their parents did,'' says 40-year-old building instructor Pat Hennin. "But they can still have a home. Like their pioneer ancestors, they can build it themselves, and at less than half the cost of a ready-made house." The owner-builders came from every occupational group, although surprisingly few are professional building workers. Many _ with little or no experience. "I learned how to build my house from reading books," says John Brown, who built a six-room home for $25, 000 in High Falls, New Jersey. "If you have patience and the carpentry skill to make a bookcase, you can build a house." An astonishing 50 percent of these owner-builders hammer every nail, lay every pipe, and wire every switch with their own hands. The rest contract for some parts of the task. But even those who just act as contractors and finish the insides of their homes can save from 30 percent to 45 percent of what a ready-made home would cost. One survey revealed that 60 percent of owner-builders also design their homes. Many others buy commercial house plans for less than $100 or use plans available from the U. S. Department of Agriculture.

Article: Different countries and cultures celebrate New Year in different ways. Many countries still follow the lunar calendar, meaning that their new year often starts in late January or in February. New Year celebrations for some countries (like China, Vietnam and Korea) last not one day, but up to two weeks! In the U.S., many people attend New Year parties. They drink champagne, dance, and cheer at the stroke of midnight. Fireworks, which in olden times scared away evil spirits, are very popular throughout the U. S. . U.S. residents often make one or more New Year's _ such as promising to quit smoking, lose weight, stop drinking. Most of these resolutions last little longer than a month. In the southern U.S. , many people eat black-eyed peas for good luck in the new year. In Mexico and Venezuela, many people wear red or yellow underwear for good luck. In Brazil, residents wear red white clothes for good luck, and in China, they wear red clothes and give children red envelops with money in them. In Iran, people wear brand new clothes on the first day of the new year. In Scotland, homeowners open the front door at midnight to let in the new year, and open the back door to let out the old year. In Switzerland, people kiss each other three times at midnight. In Spain, people eat 12 grapes-----one per chime----as the clock chimes midnight. In Japan, they ring a bell 108 times to get rid of the108 bad desires that people have. In Korea, they ring a bell 33 times in honor of 33 ancient soldiers.

How do Americans celebrate their New Year?

Article: It was my first day back home since starting college. A lot had changed in the last year. Not with my hometown but with me. I had left as a 17-year-old boy and had now returned as an 18-year-old man. In the city, I was living on my own, had a part-time job and was studying. Even the government recognized I was an adult: I had a driver's license. So here I was, on my summer vacation, walking down the main street with my father, desperate for him to acknowledge how mature I was. When his recognition failed to appear, I took matters into my own hands. "Dad," I said casually, "I'm thirsty. Let's go for a beer." It was the first time I'd ever mentioned beer in front of my father, let alone ask him to drink one with me. He turned to me with a curious expression on his face. "A beer ? Well I guess you're old enough now. Let's go to Sailors' Bar. It's where my cousin Tom, your uncle, used to drink. You remember him, right?" I had only some vague memories of my uncle. He was _ . We didn't talk about him much. "What ever happened to Uncle Tom, Dad? I haven't seen him in years," I said as we continued towards the bar. "Neither have I, unfortunately. He was a good kid once. But things changed," my father said sadly. As a boy, he explained, there had been no better-behaved boy than Tom. But after leaving school, he moved to the city and fell in with bad company. He started going out every night, drinking in nightclubs and playing cards. Soon he lost everything and had to beg his mum to pay his debts. She agreed on the condition he returned home. My dad took a deep breath and continued his tale. "Things settled down for a while. He married a lovely woman, gave up his bad habits. But it didn't last. He was soon back to his old ways. He couldn't resist. He was at Sailors' Bar almost every night. His poor mother died of grief and shame. His wife followed her soon after. "What ruined him was alcohol. He told me once, when a man begins drinking, he never knows where it'll end. 'So', Tom warned me, 'beware of your first drink!' "He went from bad to worse. Last year Tom sent me a letter saying he had been found guilty of stealing, and sent to prison for ten years." Dad finished talking just as we reached the front of Sailors' Bar. "Anyway, here we are. Let's go in," he said. But I understood. I put my arm around my father and said, "I'm not thirsty any more, Dad. Let's go home."
