As is often the case, when your teacher asks a question, there is only one correct answer. But there is one question that has millions of current answers. That question is "What's your name?" Everyone gives a different answer, but everyone is correct.

    Have you ever thought about people's names? Where do they come from? What do they mean?

    People's first names, or given names, are chosen by their parents. Sometimes the name of a grandparent or other member of the family is used. Some parents choose the name of a well-known person. A boy could be named George Washington Smith; a girl could be named Helen Keller Jones.

    Some people give their children names that mean good things. Clara means "bright"; Beatrice means "one who gives happiness"; Donald means "world ruler"; Leonard means “as brave as a lion”.

    The earliest last names, or surnames, were taken from place names. A family with the name Brook or Brooks probably lived near brook(小溪); someone who was called Longstreet probably lived on a long, paved road. The Greenwood family lived in or near a leafy forest.

    Other early surnames came from people's occupations. The most common occupational name is Smith, which means a person who makes things with iron or other metals. In the past, smiths were very important workers in every town and village. Some other occupational names are: Carter — a person who owned or drove a cart; Potter — a person who made pots and pans.

    The ancestors of the Baker family probably baked bread for their neighbors in their native village. The Carpenter's great-great-great-grandfather probably built houses and furniture.

    Sometimes people were known for the color of their hair or skin, or their size, or their special abilities. When there were two men who were named John in the same village, the John with the gray hair probably became John Gray. Or the John was very tall could call himself John Tallman. John Fish was probably an excellent swimmer and John Lightfoot was probably a fast runner or a good dancer.

    Some family names were made by adding something to the father's name. English-speaking people added –s or –son. The Johnsons are descendants of John; the Roberts family's ancestor was Robert. Irish and Scottish people added Mac or Mc or O. Perhaps all of the MacDonnell's and the McDonnell's and the O'Donnell's are descendants of the same Donnell.

    When I was growing up，I was embarrassed to be seen with my father. He was badly crippled (跛脚)，and when we would walk together，his hand on my arm for balance，people would stare，I would be ashamed of the unwanted attention.

    It was difficult to walk together—and because of that，we didn't say much as we went along. But as we started out，he always said，“You set the pace. I will try to follow you.”

    Our usual walk was to or from the subway，which was how he got to work. He went to work sick，and even in bad weather. He almost never missed a day，and would make it to the office even if others could not. It was a matter of pride for him.

    When snow or ice was on the ground，it was impossible for him to walk，even with help. At such times my sister or I would pull him through the streets of Brooklyn，N.Y.，on a child's sleigh to the subway entrance. Once there，he would try to grasp handrail until he reached the lower steps that the warmer tunnel air kept ice free. In Manhattan the subway station was the basement of his office building，and he would not have to go outside again until we met him in Brooklyn on his way home.

    When I think of it now，I am surprised at how much courage it must have taken for a grown man to suffer from shame and disability. And I am also surprised at how he did it—without bitterness or complaint.

    He never talked about himself as an object of pity，nor did he show any envy of the more fortunate or able. What he looked for in others was a “good heart”，and if he found one，the owner was good enough for him.

    Now that I am older，I believe that is a proper standard by which to judge people，even though I still don't know exactly what a “good heart” is. But I know the times I don't have one myself.

    He has been away for many years now，but I think of him often. I wonder if he sensed my reluctance to be seen with him during our walks. If he did，I am sorry I never told him how sorry I was，how unworthy I was，how I regretted it. I think of him when I complain about my troubles，when I am envious of another's good fortune，when I don't have a “good heart”．

    A warm drink of milk before bed has long been the best choice for those wanting nights sleep. But now a study has found it really does help people nod off-if it is milked from a cow at night.

    Researchers have discovered that" night milk" contains more melatonin(褪黑激素) which has been proven to help people feel sleepy and reduce anxiety.

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

    Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.

    Night milk quickened the start of sleep and caused the mice to sleep longer.

    While the effect of cows milk 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 fall asleep at night.

    Early studies have also showed that milk can be excellent for helping sleep because of containing Ca., which helps people to relax.

    Milk is also sugar-free and additive-free(不含添加物的) with experts advising skimmed (脱脂的) milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.

    Animals, including insects, do not have a language like ours. They do not talk to each other in words and sentences. But if we watch them, we can see that they do have ways of communicating with each other.

    Can you see the rabbits' tail? When rabbits see this white tail moving up and down, they run too. The rabbit has reminded them of potential dangers without making a sound. It has given them a signal.

    Many other animals use this kind of language. When a cobra (眼镜蛇) is angry, it raises its hood (兜帽) and makes itself look fierce. This warns other animals. When a bee has found some food, it goes back to its home. It cannot tell the other bees where the food is by speaking to them, but it does a little dance in the air. This tells the bees where the food is.

    Some animals say things by making sound. A dog barks, for example, when a stranger comes near. A cat purrs (猫的呜呜声) when pleased. Some birds make several different sounds, each with its own meaning. Sometimes we human beings speak in the same way. We make sounds like “Oh” or “Ah!” when we are frightened or pleased or when we drop something on our toes.

    But we have something that no animals have — a large number of words which have the meanings of things, actions, feeling or ideas. We are able to give each other all kinds of different information in words and sentences, which no other animals can do. No other animals have so wonderful a language as we have.

    Yoga is an ancient physical and spiritual practice originating in India. The word '"yoga" comes from Sanskrit (梵文) and means to join or to unite, symbolizing the union of body and mind. Today it is practiced in various forms around the world and continues to grow in popularity. Recognizing its universal appeal, the United Nations declared 21 June as the International Day of Yoga in 2014 to raise awareness worldwide of the many benefits of practicing yoga.

    Yoga is an invaluable gift from an ancient tradition. It's not just about exercise but a way to discover the sense of oneness with yourself nature and the world. There is no written record of who invented yoga. Yoga practitioners (从业者) passed down the principles to their students. The earliest written record of yoga is generally believed to have been written by Patanjali, an Indian master who lived somewhere between 2,000 and 2,500 years ago.

    Various yoga types give you multiple choices. Hatha yoga is the most widely practiced type and is excellent for beginners. It is gentle with slow and smooth movements. Kundalini yoga combines a singing session besides body and mental control. Bikram yoga is practiced in a heated room. It is to loosen muscles and to sweat to clean the body and remove symptoms of disease and pain. Ashtanga yoga is taught as a difficult workout where you move quickly from one gesture to another to build strength and patience.

    In recent years, the World Health Organization has urged countries to help their citizens reduce physical inactivity, which is among the top ten leading causes of death worldwide, and a key risk factor for non-communicable diseases, such as cancer and diabetes. Yoga is a proper exercise. It is known for its ability to ease stress and anxiety. It may also help reduce several risk factors for heart diseases and promote a better sleep.
