Question: 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.
Answer: Many people attend New Year parties.

Answer: How do Americans celebrate their New Year?

Question: Article: Every immigrant leads a double life. Every immigrant has a double identity and a double vision, being suspended between an old and a new home, an old and new self. The very notion of a new home, of course, is in a sense as impossible as the notion of new parents. Parents are who they are; home is what it is. Yet home, like parentage, must be legitimized through love; otherwise, it is only a fact of geography or biology. Most immigrants to America found their love of their old homes betrayed: they did not really abandon their countries; their countries abandoned them. In America, they found the possibility of a new love, the chance to nurture new selves. Not uniformly, not without exceptions. Every generation has its Know-Nothing movement. Its understandable fear and hatred of alien invasion is as true today as it always was, but in spite of all this, the American attitude remains unique. Throughout history, exile has been a disaster; America turned it into a triumph and placed its immigrants in the center of a national epic. The epic is possible because America is an idea as much as it is a country. America has nothing to do with loyalty to a dynasty and very little to do with loyalty to particular place, but everything to do with loyalty to a set of principles. To immigrants, those principles are especially real because so often they were absent or violated in their native lands. It was no accident in the '60 and '70s, when alienation was in flower, that it often seemed to be "native" Americans who felt alienated, while aliens or the children of aliens upheld the native values. The immigrant's double vision results in a special, somewhat skewed perspective on America that can mislead but that can also find revelation in the things that to native Americans are obvious. Psychiatrist Robert Coles speaks of those "who straddle worlds and make of that very experience a new world." "Home is where you are happy." Sentimental, perhaps, and certainly not conventionally patriotic, but is appropriate for a country that wrote the pursuit of happiness into its founding document. That continues for the immigrant in America, and it never stops, but it comes to rest at a certain moment. The moment is hard to pin down, but it occurs perhaps when the immigrant's double life and double vision joint together toward a single state of mind. When the old life, the old home fade into a certain unreality: places one merely visits, in fact or in the mind, practicing the tourism of memory. It occurs when the immigrant learns his ultimate lesson: above all countries, America, if loved, returns love.
Answer: Immigrants have played an important role in America's history.

Answer: What's the result of American's unique attitude toward immigrants?

Question: Article: Except for the sun, the moon looks like the biggest object in the sky. Actually it is one of the smallest, and only looks big because it is so near to us. Its diameter is only 2,160 miles (3,389 km), or a little more than a quarter of the diameter of the earth. Once a month, or more exactly, once every 29.5 days, at the time we call "full moon," its whole _ looks bright. At other times only part of it appears bright, and we always find that this is the part which faces towards the sun, while the part racing away from the sun appears dark. People could make their pictures better if they kept this in mind -- only those parts of the moon which are lighted up by the sun are bright. This shows that the moon gives no light of its own. It only throws back the light of the sun, like a huge mirror hung in the sky. Yet the dark part of the moon's surface is not ly black; generally it is just light enough for us to be able to see its outline, so that we speak of seeing "the old moon in the new moon's arms." The light by which we see the old moon does not come from the sun, but from the earth. We know well how the surface of the sea or of snow, or even of a wet road, may throw back uncomfortably much of the sun's light onto our faces. In the same way the surface of the whole earth throws back enough of the sun's light on to the face of the moon for us to be able to see the parts of it which would otherwise be dark.
Answer: Because the earth throws back sunlight onto the moon.

Answer:
Why is the dark part of the moon not completely black?
