Recently, professor of philosophy (哲学)in the United States has written a book called Money and the Meaning of Life. He has discovered that how we deal with money in our daily life has more meaning than we usually think. One of the exercises he asked his students to do is to keep a record of every penny they spend for a week. From the way they spend their money, they can see what they really value in life.

    He says our relations with others often become dearly defined (清晰的）when money enters the picture. You might have wonderful relationship with somebody and you think that you are very good friends. But you will know him only when you ask him to lend some money. If he does, it brings something to the relationship that seems stronger than ever before or it can suddenly weaken the relationship if he doesn't. This person may say that he has a certain feeling, but if it is not carried out in the money world, there is something less real about it.

    Since money is so important to us, we consider those who possess a lot of it to be very important. The author interviewed some millionaires in researching his book.

    Question: What is the most surprising thing you have discovered about being rich, because you are a self-made man?

    Answer: The most surprising thing is how people give me so much respect. I am nothing. I don't know much. All I am is rich.

    People just have an idea of making more and more money, but what is it for? How much do I need for any given purposes in my life? In his book, the professor uncovered an important need in modem society: to bring back the idea that money is an instrument rather than the end. Money plays an important role in the material world, but expecting money to give happiness may be missing the meaning of life.

    A machine that takes sweat-laden (浸满汗水的) clothes and turns the sweat into drinking water is in use in Sweden. The machine makes the clothes turn round quickly, heats them to remove the sweat, and then passes the steam through a kind of special material to make purified water.

    Since it has been brought into use, its creators say more than 1000 people have drunk others' “sweat” in Gothenburg. They add the liquid is cleaner than local tap water.

    The device was built for the United Nations' child-focused charity UNICEF to promote a campaign highlighting the fact that 780 million people in the world lack access to clean water.

    The machine was designed and built by the engineer Andreas Hammar, known locally for his appearances on TV tech show “Mekatronik”. He said the key part of the sweat machine was a new water purification part developed by a company named HVR.

    “It uses a technique called membrane distillation (膜蒸馏),” he told the BBC. “We use a special kind of material that only lets steam through but keeps bacteria, salts, clothing fibers and other things out. They have something similar to the International Space Station, but our machine is cheaper to build. The amount of water it produces depends on how sweaty the person is, but one person's T-shirt typically produces 10ml, about a mouthful.”

    The device has been put on show at the Gothia Cup-the world's largest international youth football tournament. Mattias Ronge, chief executive of Stockholm-based advertising agency Deportivo, said the machine had helped raise awareness for UNICEF, but in reality had its limitations.

    “People haven't produced as much sweat as we hoped – right now the weather in Gothenburg is lousy,” Mattias Ronge said. “So we've equipped the machine with exercise bikes and volunteers are cycling like crazy. Even so, the demand for sweat is greater than the supply. And the machine will never be produced in large numbers, since there are better solutions out there such as water purifying pills.”

    A couple from Miami, Bill and Simone Butler, spent sixty-six days in a life-raft in the seas of Central America after their boat sank.

    Twenty-one days after they left Panama in their boat, Simony, they met some whales. “They started to hit the side of the boat” said Bill, “and then suddenly we heard water.” Two minutes later, the boat was sinking. They jumped into the life-raft and watched the boat go under the water.

    For twenty days they had tins of food, biscuits and bottles of water. They also had a fishing-line and a machine to make salt water into drinking water—two things which saved their lives. They caught eight to ten fish a day and ate them raw（生的）. Then the line broke. “So we had no more fish until something very strange happened. Some sharks came to feed, and the fish under the raft were afraid and came to the surface. I caught them with my hands.”

    About twenty ships passed them, but no one saw them. After fifty days at sea their life-raft was beginning to break up. Then suddenly it was all over. A fishing boat saw them and picked them up. They couldn't stand up. So the captain carried them onto his boat and took them to Costa Rica. Their two months at sea was over.

    Have you ever found yourself in this situation: You hear a song you used to sing when you were a child – a bit of nostalgia(怀旧) or "blast from the past," as we say. But it is not a distant childhood memory. The words come back to you as clearly as when you sang them all those years ago.

    Researchers at the University of Edinburgh studied the relationship between music and remembering a foreign language. They found that remembering words in a song was the best way to remember even one of the most difficult languages.

    Here is what they did. Researchers took 60 adults and randomly divided them into three groups of 20. Then they gave the groups three different types of "listen-and-repeat" learning conditions. Researchers had one group simply speak the words. They had the second group speak the words to a rhythm, or beat. And they asked the third group to sing the words.

    All three groups studied words from the Hungarian language for 15 minutes. Then they took part in a series of language tests to see what they remembered.

    Why Hungarian, you ask? Researchers said they chose Hungarian because not many people know the language. It does not share any roots with Germanic or Romance languages, such as Italian or Spanish. After the tests were over, the singers came out on top. The people who learned these new Hungarian words by singing them showed a higher overall performance. They did the best in four out of five of the tests. They also performed two times better than those who simply learned the words by speaking them.

    Dr. Katie Overy says singing could lead to new ways to learn a foreign language. The brain likes to remember things when they are contained in a catchy 3, or memorable 4, tune 5.

    Dr. Ludke said the findings could help those who struggle to learn foreign languages. On the University of Edinburgh's website Dr. Ludke writes, "This study provides the first experimental evidence that a listen-and-repeat singing method can support foreign language learning, and opens the door for future research in this area."

    My husband and I wanted desperately the instant transformation from typical consumers to eco-conscious people. We switched our light bulbs to CFL(compact fluorescent light) bulbs to conserve energy. We went about the house turning off lights and unplugging appliances that weren't in use. But the rate of global warming exceeded our snail's pace conversion to greenhood. So I pressed onward.

    I decided to put veganism(素食主义) at the top of our agenda. Vegans refuse any animal flesh or commercial goods made from any animal byproducts such as milk or fats. All the family applauded this option except for my husband. Some kind of animal needed to sacrifice its dear life for his meal or it was his dinner. I cooked up a storm, struggling to prepare nutritious meals dominated by not-so-obvious vegan dishes like bean burritos and high-fiber vegetable stir-fry. It took a few days before he realized that he hadn't been eating any meat.

    "I feel like eating beef." he announced. So that night, I took full advantage of a zucchini (一种南瓜), cut it into chunky(粗大的) pieces and cooked them. Then I covered them with spices. My beef-starved husband had some and a curious look crossed his face.

    "Where's the beef?"

    "Living peacefully somewhere on an open plain where it belongs."

    "I knew it" he murmured. "You've surely made great contributions to the boom in cattle." His taste buds were developed completely around the flavor of every kind of animal: cattle, pigs, deer, lamb, chickens and ducks. Converting him was like feeding grass to a lion.

    I'm all for preserving our planet, but what good would it do to save the earth for tomorrow's generation if today's died of starvation? The next day, we went out for burgers. I was very careful to place the paper bag into our recycling bin.

    The impression you make at the beginning of an interview is very important. Employers often decide to hire someone in the first three minutes of the interview. They judge you by your appearance, attitude and manners.

    A friendly smile when you walk into the room is important. A smile shows a confident and positive attitude.

    When you introduce yourself, make eye contact with the interviewer. Some interviewers offer a handshake. Others don't.

    Try to be as natural as possible. But pay attention to your body language. The way you sit, walk, gesture, use your voice and show feelings on your face is all part of your body language. It makes the interviewer know how you feel about yourself and the situation you are in. Are you feeling positively about yourself? Your abilities? Your interest in the job?

    Speak clearly and loudly enough. Show interest and enthusiasm in your voice. When you speak, look at the interviewer. Also, don't say negative things about yourself, or former employer.

    Listen to questions carefully. If you don't understand a question, ask the interviewer to repeat or explain:

    "I'm sorry, but I didn't catch that."

    "I'm not sure exactly what you mean."

    Almost everyone is nervous in a job interview. Interviewers know that. They don't expect you to be totally calm and relaxed. But they expect you to try to control your nervousness. They expect you to show confidence in your ability to do the job.

    At the end of the interview, thank the interviewer for her or his time.

    It's a good idea to send a short thank-you letter right after the interview, or deliver it by hand.

    Phone the company if you have not heard anything after one week. Ask if they have made a decision about the job.

    Good luck!
