A warm drink of milkbefore bed has long been the best choice for those wanting a good night'ssleep. But now a study has found it really does help people nod off—if it ismilked from a cow at night.

  Researchers have discovered that“night milk” contains more melatonin(褪黑激素), which has been proven tohelp people feel sleepy and reduce anxiety.

  The study, by researchersfrom Seoul, South Korea, involved mice being fed with dried milk powder madefrom cows milked both during the day and at night.

  Those given night milk, whichcontained 10 times the amount of melatonin, were less active and less anxiousthan those fed with the milk collected during daytime, according to the studypublished in The Journal of MedicinalFood.

   Night milk quickened the startof sleep and caused the mice to sleep longer.

   While the effect of cowsmilk harvested at different time has not been tested on humans up to now,taking melatonin drugs has been suggested to those who are struggling to fallasleep at night.

   Previous studies have alsoindicated that milk can be excellent for helping sleep because of the calciumcontent, which helps people to relax.

  Milk is also sugar-free andadditive-free with nutritionists recommending skimmed milk as the best choicebefore bed as it is the least fattening. The more fat you take in beforebedtime, the greater burden you will put on your body at night.

    A generation ago young people longed to become lawyers and doctors. Now they desire to be the next Oscar winner or famous pop star. But one university psychologist has pointed out that this is damaging our self-image and sense of self-worth. Over recent years people around the world have been suffering from an increasing fear of their own “insignificance”, according to Dr. Strenger of Tel Aviv University.

    He began a project on the phenomenon 10 years ago, after noticing an increase of fear in his own patients. His findings note hundreds of research projects that have recorded an unprecedented (前所未有) increase in levels of anxiety and depression. By using a wide-ranging framework Dr. Strenger thinks he has given the accurate cause. “The impact of the global entertainment network on the individual is to blame,” he said. “A new species—global man—is born and we are defined by our close connection to the global entertainment network, which has turned ranking and evaluating people according to wealth and fame into an obsession (狂热).”

    As humans we naturally measure ourselves by those around us, but now we live in a “global village” where we are comparing ourselves with the most “significant” people in the world - and finding ourselves not good enough. Today, even high achievers constantly fear that they are insignificant when they compare themselves to success stories in the media. “This creates highly unstable personality and an unstable society,” Dr. Strenger said.

    Dr. Strenger says people should stop measuring their achievement through the cultural fantasies of rich and famous people. The remedy (治疗方法) is a process that he calls “active self-acceptance” through a continuing search for self-knowledge through life. The fear of insignificance can only be overcome through strong individual and cultural identity over and above measurable achievement. “People should invest time and thought in their personal growth from different aspects in the same way they invest in medical studies and law school,” Dr. Strenger advises.

    Tenzing left his home when he was ten to work and help his mother, who was looking after their 2-acre ancestral farm after his father's death. He did temporary jobs for the first few years and then joined a Malaysian construction firm, where he learnt to drive, repair machines, work on the Internet and even speak English fluently.

    “In those 13 years, I learnt everything—driving, mechanic work, and how to set up a small factory. This made me gain much confidence to do almost all jobs,” says Tenzing.

    However, as his mother was getting older, on December 12, 2006, Tenzing returned to his hometown in Assam. Having visited several farms, he came to know that tea could be easily exported and many tea companies were buying tea; so he also decided to grow tea on his farm. But as his family had never grown tea, he had no idea how to do it.

    Being a green hand in this field, Tenzing went to meet with many tea experts and followed their instructions. But whenever he sprayed pesticide (农药)on his farm, he'd get a headache and feel indisposed. So he started looking for alternatives. Tenzing did his research online and finally in 2007, he connected with people from a Canadian non-governmental organization and invited them to his farm, where they trained him. Thus, Tenzing started growing tea organically.

    Today Tenzing has 25 acres of land, of which 7.5 acres is used for tea planting, and he grows almost all types of fruits and vegetables. His success inspired many, and farmers from other parts of the country also started coming to his farm to learn organic farming. He has trained about 30,000 farmers so far. Every year almost 100 tourists visit his farm from various parts of the world like the UK, Australia, Germany, etc.

    Black Friday

    The day after Thanksgiving is the start of the holiday shopping season. Thanksgiving is always on a Thursday, so the day after is a Friday. This day has come to be known as Black Friday. It has been the busiest shopping day of the year since 2005.

    Most stores offer great deals on Black Friday. They open their doors in the small hours of the morning. They try to attract shoppers with big discounts. Some items like TVs are much cheaper than usual. Stores may even lose money on these items. They hope that shoppers will buy gifts for other people while they are in the store.

    Black Friday is a great time to get good deals. The problem is that there are not enough low-priced items to go around. Each store may only have a few. These items are in high demand. People stand in long lines to get such great deals. They may line up hours before a store opens. They may be hoping to get a low price on a TV or laptop, but not everyone who wants one will get one. Some people leave disappointed.

    The situation can be tense(紧张的). Some Black Friday events have been violent. Large, eager crowds have trampled(践踏) workers. Fights have broken out over toys or people cutting in line. People have shot one another over parking spots. But most Black Friday events are safe and fun. Still, if you plan on going, expect large crowds and a bit of pushing and shoving.

    So where does the name "Black Friday" come from? It was first used in Philadelphia in the 1950s. The police called this day Black Friday because of the heavy traffic it drew. In the 1960s, spread across the country. It seems that it is here to stay.

    Now people all over the country take part in the event known as Black Friday. It is even spreading to other parts of the world. Stores have held Black Friday events in the U.K., Australia, and Brazil since 2012. In Costa Rica Black Friday is known as "Viernes Negro." And in Mexico, stores offer an annual weekend of discounts. They call it "El Buen Fin," which means "the good weekend" in Spanish. I guess the language of savings is universal.

It is amazing how many of the things in science fiction and movies have become reality.For instance,in the movie Star Trek,the workers could go to a replicator(复制器) and order food,drinks or anything they could program into the computer.Before long,the item would appear.This is possible today,in a way,with technology we have had for years.

Several manufacturers(制造商) have created 3D printers.One company,MakerBot,has created a printer that the average person can afford.It is called The Replicator.You can download a lot of design software from the Internet for use with The Replicator.In the near future,rather than going to a store to buy what you need,you may be able to download what you want from the Internet and print it out at home.

The process was first used with music.At the very beginning,music was recorded onto plastic disks with etching(蚀刻法).Music can now be copied without a physical product.____ Rather than having to buy a physical book or magazine,you can now download them from the Internet in digital form.

This technology is already used in engineering and architecture.Melissa Shoes,a Brazilian foot wear company,is using this technology to create shoes.Rather than having to go through the current process of product design and development,the company is able to design and print shoes for display to see how well they will sell before having lots of them made.
