　　I'm Rich Kleinfeldt with some financial expressions used in business and the stock market．

　　Our first expression is "in the red．"　It is another way of saying that a business is losing money．In the past, numbers in the financial records of a company were written in red ink to show a loss．

　　A business magazine recently published a report about a television company．The report said the company was still in the red, but was able to cut its loss from the year before．

　　A profit by a business is written in black numbers．So a company that is "in the black" is making money．

　　Another financial expression is "run on the bank．" That is what happens when many people try to withdraw all their money from a bank．A "run on the bank" usually happens when people believe there is danger a bank may fail or close．

　　Newspaper reports about a banking crisis in Russia used that expression．They said the government acted because of fears that the crisis would cause a run on the banks．

　　"Day trading" is a system that lets investors trade directly on an electronic market system．It was the first completely computerized stock market．It sells stocks of companies not listed on any stock exchange．Many high technology companies are listed on it．

　　Day trading companies provide a desk and a computer system to an investor who wants to trade．Individuals must provide fifty thousand dollars or more to the trading company to pay for the stocks they buy．Thousands of other investors do day trading from computers in their homes．

　　A day trader watches stock prices carefully．When he sees a stock rise in price, he uses the computer to buy shares of the stock．If the stock continues to rise in price in the next few minutes, the day trader sells the shares quickly to make a small profit．Then he looks for another stock to buy．If a stock goes down instead of up, he sells it and accepts the loss．

　　The idea is to make a small profit many times during the day．Day traders may buy and sell stocks hundreds of times each day．

　　In eighteen seventy-seven, the American government decided to move the Nez Perce Indians from their land．The government had set up a reservation for them in Idaho．Chief Joseph did not want to leave the land．It was holy ground．It contained the bones of his father and mother．

　　But, like his father in earlier times, Chief Joseph knew it would be hopeless to stay and defend the land．There were too few Indians to win a war against the white men．

　　And so in June of eighteen seventy-seven, the Nez Perce left their home in the Wallowa Valley．They left quickly．They were able to take only a small part of what they owned, and just a few cattle and Appaloosa horses．

　　When the Indians reached the Snake River, the water was very deep and ran very fast with melted snow from the mountains．Chief Joseph and his people made boats from sticks and dried animal skins to cross the river．While the Indians were busy, a group of white men came and stole some of the cattle waiting at the edge of the river．

　　The other chiefs demanded that Joseph call a meeting．Two of the chiefs, White Bird and Toohoolhoolzote, spoke for War, but Joseph held different opinion．

　　Some of the young men in White Bird's group were very angry．That night, they rode into the countryside and killed eleven white persons．

　　During all his years as chief, Joseph had tried to keep the peace．Now he saw there was no hope．Although he and his young men had taken no part in the killings, he knew that the white men would blame all of the Indians．Chief Joseph said, "I would have given my own life if I could have undone the killing of the white men．"

　　Many Nez Perce fled．Chief Joseph remained, because his wife was about to have a baby．After she gave birth, he and his family joined the others in White Bird Canyon to the south．

　　Joseph wanted to lead the people to safety in the flat lands of Montana．But the United States army quickly sent horse soldiers to follow them．

　　They were extremely tired when they reached White Bird Canyon．An Indian－carrying a white flag－walked forward to meet them．A soldier shot him．

　　With that shot, war between the Nez Perce and the United States began．

　　Cells were discovered in 1665 by Robert Hooke when he took a piece of cork and looked at it under a microscope．Cork is made up of dead cells but you are still able to see the cells which proved to be interesting to him．He described it as being made of something, just like a wall is made of bricks．He then called those bricks “cells”．Due to the size of cells, it is nearly impossible to see them without the aid of a light microscope, but by using an electron microscope you'd be able to see cells in much greater detail．

　　There's a cell theory which is made up of four basic ideas．First, cells are the building blocks of life．Second, cells are derived from other cells by division．Third, cells contain DNA(the blueprint for life)．Fourth, the cell is the functioning unit of life, and the chemical reactions of life take place within cells．

　　There are two types of cells, animal cells and plant cells．Plant cells differ from animal cells in many ways．Plant cells have a large central vacuole(液泡), with the nucleus(细胞核)nearer to the side of the cell instead of in the middle like in animal cells．Another big difference is that plant cells can produce and store sugar as starch(淀粉)while animal cells contain glycogen(糖原)．

　　It's noteworthy to mention that a cell cannot survive without the nucleus which acts as a type of control center; it runs the cells．The nucleus contains DNA, which in turn contains the cell's genes．These genes tell the cell how to grow．DNA contains the genetic blueprint that tells if you have blonde hair and blue eyes．

　　The parents of a troubled teen may feel unsure as to whom to turn to in order to find help for their child．They may feel as if they have exhausted all of their options, and sometimes they are on the verge of giving up．But there is hope．Schools for troubled teens offer discipline and in some cases, drug treatment programs that can provide important life skills, and more importantly, a fresh start．

　　The following is a list of the most effective types of schools for troubled teens．Not every facility is a match for every child, but by knowing the differences between them, parents can make a better educated decision about where to send their teenager．

　　Boarding Schools

　　When a child is unable to deal with the relative freedom of a standard school day, boarding schools might be a good choice．At boarding schools, the child lives in a dorm setting, where almost every minute of the day is scheduled by school administrators．

　　Treatment Centers

　　When a teenager has an addiction to drugs or alcohol, a residential center that specializes in young people is an outstanding way to help them break the cycle of addiction．Treatment centers feature individual and group counseling to help identify the root causes of the drug problem and help develop the life skills needed to stay clean when the program is over．

　　Wilderness Programs

　　Designed to help improve the discipline and self-reliance of the child, wilderness programs send kids back to nature．By placing them in a foreign and sometimes uncomfortable setting, wilderness programs hope to improve children's behavior．Programs generally include hikes, exercise programs and team building exercises．

　　Boot Camps

　　Boot camps are the most extreme style of school for troubled teens．These facilities are modeled after actual military boot camps, where the individual must get into shape, work as part of a team, and follow a long, hard set of rules and regulations．However, boot camps might not be the best choice for a teen with a drug addiction．

　　China news, Beijing, Feb．9-Housing price in China has always aroused heated discussions among property developers and ordinary Chinese．To many property developers and local government officials, housing price in China is still low compared with many developed countries．However, the average housing price in the United States is only 8, 000 Yuan per square meter, while in China, it is even higher than in the United States．This shows that there are some bubbles(泡沫)in Chinese real estate market, the International Finance News reported．

　　Although the average price of residential houses in the United States, after converted to Renminbi, is about 8, 000 Yuan per square meter, the houses in US are not sold in terms of building area, as most Chinese property developers do when they sell their houses．If US property developers sell their houses according to the building area, then the housing price will be even lower than 8, 000 Yuan per square meter．In most big Chinese cities, such as Beijing, Shanghai, and Shenzhen, houses are sold at a price even higher than those in the US．

　　The high housing sales price in large cities in China proves that Chinese real estate market

　　does have some bubbles．Moreover, Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities．Furthermore, it should be noted that American people's average income is several dozen times higher than that of Chinese people．How can the Chinese afford to buy a house which is even more expensive than that sold in the US?

　　At the beginning of 2007, Chinese government issued a set of policies that aimed to benefit the public．Now in order to reduce the high housing prices, the government can regulate(控制)the real estate market by raising tax on property industry and controlling the release of loans and lands to property developers．At the same time, the government should allow people to build more houses through various fund-raising channels, such as funds collected from buyers or raised by working units．By applying these multiple means, it is expected that the high housing prices can be lowered．

　　I was parked in front of the mall wiping off my car．I had just come from the car wash and was waiting for my wife to get out of work．

　　Coming my way from across the parking lot was what society would consider a bum．From the looks of him, he had no car, no home, no clean clothes, and no money．There are times when you feel generous but there are other times that you just don't want to be bothered．This was one of those "don't want to be bothered times"．

　　" I hope he doesn't ask me for any money, " I thought．

　　He didn't．He came and sat on the edge of the pavement in front of the bus stop but he didn't look like he could have enough money to even ride the bus．After a few minutes he spoke．

　　"That's a very pretty car, " he said．

　　He was in rags but he had an air of dignity around him．His badly-grown blond beard kept more than his face warm．

　　I said, "thanks, " and continued wiping off my car．He sat there quietly as I worked．The expected plea(乞求)for money never came．As the silence between us widened, something inside said, "ask him if he needs any help．" I was sure that he would say "yes" but I held true to the inner voice．

　　"Do you need any help? " I asked．

　　He answered in three simple words that I shall never forget．We often look for wisdom in great men and women．We expect it from those of higher learning and achievements．I expected nothing but an outstretched dirty hand．He spoke the three words that shook me．

　　"Don't we all? " he said．

　　You know how wonderful you are, and you know that others know how wonderful you are, but what do you do when admiration crosses over the line into jealousy? For most teens there will come a day when you realize that one of your friends is jealous and that this jealousy is hurting your friendship．When it happens, there is nothing that you can do, but the good news is that there is．Don't let jealousy spoil your relationships．Deal with it at once and you might be back to normal much sooner than you think．

　　It can be hard to walk up to a friend and ask them what the problem is, but if you want to save your friendship you'll have to do just that．Don't approach them and ask why they are jealous of you, just take some time alone with them and let them know that you've been feeling like there's been something coming between you．If they refuse to respond, then use the opportunity to explain how you have been feeling．Chances are that something you say will strike a nerve and your friend will open up as well．

　　When you figure out what is annoying your friend, ask him or her what(s)he thinks would make the situation better．If, for example,(s)he says that(s)he feels like(s)he doesn't want to spend any time with you because you are always with your new friends from swim team then maybe you could invite him or her along the next time, just the two of you．Remember, though, that whatever solution you decide on should be a compromise．Don't limit your own talents or opportunities simply because your friend is unhappy．Try instead to include him or her in your new life and see how that works out．

　　Even the best of friendships can be ruined by jealousy．This destructive emotion is rarely productive and can turn best friends into worst enemies．Before taking extreme action, chat with your jealous friend to see if the two of you can work out a compromise．If you can't, be prepared to know exactly how far you will go to keep your friend and how far you won't．

　　Two Christmas traditions have come under attack in recent years from environmentalists： Christmas cards and Christmas trees．

　　Paper cards are seen as wasteful and, for some people, going card? free is another way of going green．They also argue that in a world of e-mail, Skype, Facebook and Twitter, people are in touch all the time anyway; they no longer need the yearly card that connects them with long lost friends．If you want to send Christmas greetings, there are free e-cards, which get the job done with no postage or wasted paper．

　　However, especially tor people who didn't grow up with e-mail, there is something missing from a Christmas e-mail．The first Christmas cards appeared in London in 1843 and were designed by the same man who had introduced the world's first postage stamp three years earlier．His name was Sir Henry Cole．

　　They rose in popularity throughout the 20th century．Many people sent cards that were sold for charity．The most famous of these are the ones sold for UNICEF．In the UK this year, in the three weeks before Christmas, the post office expects to handle 100 million cards every day．Environmental awareness also means that nowadays many people recycle their cards; this helps raise money to plant more trees, as well as recreating more paper．

　　When we think of trees at Christmas, there is one that immediately springs to mind-the evergreen tree that people decorate with ornaments and place their presents under．The custom dates back almost a thousand years to Germany, Nowadays 33 to 36 million Christmas trees are produced in America and 50 to 60 million in Europe each year．Some trees are sold live with roots and soil so people can plant them later and reuse them next year．

　　Some people prefer artificial trees as they are reusable and much cheaper than their natural alternative．However, environmentalists point out that they are made from petroleum products and they have much pollution．

　　"Dr．Papaderos, what is the meaning of life? "

　　The usual laughter followed, and people stirred to go．Dr．Papaderos held up his hands and stilled the room and looked at me for a long time, asking with his eyes if I was serious and seeing from my eyes that I was．

　　"I will answer your question．"

　　Taking his wallet out of his hip pocket, he fished into a leather wallet and brought out a very small round mirror, about the size of a quarter．And what he said went like this： "When I was a small child during the war, we were very poor and we lived in a remote village．One day, on the road, I found the broken pieces of a mirror．A German motorcycle had been broken in that place．

　　I tried to find all the pieces and put them together, but it was not possible, so I kept only the largest piece．This one．and, by scratching it on a stone, I made it round．I began to play with it as a toy and became fascinated by the fact that I could reflect light into dark places where the sun would never shine-n deep holes and crevices(裂缝)and dark closets．It became a game for me to get light into the most inaccessible places I could find．

　　I kept the little mirror, and, as I went about my growing up, I would take it out in spare time and continue the challenge of the game．As I became a man, I got to understand that this was not just a child's game but a metaphor for what I might do with my life．I came to understand that I was not the light or the source of light．But light-truth, understanding, knowledge-is there, and it will shine in many dark places only if I reflect it．

　　I am a fragment of a mirror whose whole design and shape I do not know．Nevertheless, with what I have I can reflect light into the dark places of this world-into the black places in the hearts of men-and change some things in some people．Perhaps others may see and do likewise．This is what I am talking about．This is the meaning of my life．
