For the past four days, the streets of India have been brightly lit and full of festivities. Millions of people around the country have been celebrating the festival of Diwali.

    Diwali has been celebrated in India for hundreds of years. It takes place each year in either October or November. Although the holiday lasts only one night, people continue to celebrate for several days.

    People light oil lamps during the festival. In the tradition of the Hindu religion, the lamps are meant to celebrate the victory of light over darkness and good over evil (邪恶). The holiday also celebrates the start of a new year in the Hindu calendar. But Diwali is an important festival in many other Indian religions as well, including Sikhism and Jainism. In a country of more than 1.2 billion people and different religious beliefs, Diwali is a celebration that touches everyone.

    Diwali means “rows of lamps” in Sanskrit, a language used in many Indian religions. During the festival, families and friends come together to light the oil lamps，which are called diyas. Then they put the lamps in rows outside their homes and temples.

    As in other cultures' winter holidays，sweets and gifts are also a big part of Diwali. Neighbors and friends share treats, called mithai, and exchange presents.

    Employers often use the holiday to express appreciation for their workers. This year, a businessman even bought cars and houses for some of his employees!

    The Diwali spirit can be felt outside India as well. Indians in countries around the world, including the U. S. and Canada，are also celebrating the holiday this week.

    Many people go to school for an education. They learn languages, history, geography, physics, chemistry and mathematics. Others go to school to learn a skill so that they can make a living. School education is very important and useful. Yet no one can learn everything they want to know. The teacher's job is to show his students how to learn. He teaches them how to read and how to think. So, much more is to be learned outside school by the students themselves.

    It is always more important to know how to study by oneself than to memorize some facts or a formula (公式). It is usually quite easy to learn a certain fact in history or a formula in mathematics. But it is very difficult to use a formula in working out a maths problem. Great scientists, such as Einstein, Newton and Galileo didn't get anything from school. But they were all so successful. They invented so many things for mankind.

    The reason for their success is that they knew how to study. They read books that were not taught at school. They worked hard all their lives, wasting not a single moment. They would ask many questions as they read and they did thousands of experiments.

    Above all, they knew how to use their brains.

    It was a cold winter. The wind blew all night and the snow was blinding. When morning came, my three children and I got up and made our way to the windows. As we looked out the window, we saw that the henhouse was gone. Our three hens had been blown away.

    I looked at the emptiness outside. Then I saw all three chickens sat around the edge of a white bucket. How was this violent wind not blowing them into the field beyond? I quickly pulled on long snow pants and heavy winter coat, wrapped a scarf and stuck my feet into very large boots .

    I shouted at the wind as it blew. I was alone, save for my children. They stared out the window into the vast white sea of snow, their eyes peeled for any sign of movement. Outside I heard the sound of my boots as I walked against the wind.

    The snow circling around me, I steadily made my way to the soft cluck-cluck-cluck sound my hens always made. When I reached them, I saw that their little feet were holding on to the edge of the bucket, heads bent forward and away from the wind. I gently lifted each hen and put it carefully into the warm inside. Then I began the freezing walk back to the small shed directly behind our house. One by one I laid my chickens on the cold floor, and they began to cluck softly.

    As I shut the shed doors, my eyes went directly to the window where my children were watching. They jumped up and down cheering, and so did I! I wasn't some dragon slayer (屠龙者) from a fairy tale. I was simply a mom, but the look on my children's faces told me that they thought I was a hero mom.

    Organic(有机的)farming is a type of agriculture that benefits from the recycling and use of natural products. Use of dried plants not only saves money，but also ensures the growth of crops. The technique is characterized by the use of green manure(肥料), biological pest control methods and special farming techniques to keep soil productive. Limiting the use of man－made chemicals or completely doing away with them reduces the risk of diseases. Today，organic farming is a major and preferred industry around the world. Organically grown food products have a huge market，with farmlands covering about 10% of the total world－farmland cover. The hard work of Sir Albert Howard, the Father of Organic Farming, has paid off.

    Advantages of Organic Farming:

    ⑴The economics of organic farming are characterized by increasing profits through reduced water use and reduced soil erosion(侵蚀).

    ⑵Organic farming produces the same crops as those produced through traditional farming methods，but uses half the energy，and holds 40% more top soil

    ⑶Farming the organic way enables farmers to get rid of weeds without the use of any chemicals.

    ⑷The use of green pesticides(杀虫剂) is environmentally friendly and does no harm to human's health.

    Disadvantages of Organic Farming：

    ⑴Organic methods of farming produce less，compared to traditional farming techniques.

    ⑵Organic agriculture does little to fight global climate change. Though organic farming practices are recognized as giving out less CO₂ ， but not to a significant degree.

    However，though there are some disadvantages of organic farming，farms where organic methods for cropping have been used have more advantages than traditional farms. Organic agriculture is surely better in the long term.

    Helen Keller was one of America's best-known women. She was admired for her courage and achievements although she couldn't see or hear. She was also known throughout the world for herself-sacrificing work to improve the condition of the blind, the deaf and the speechless. When she died on June 1, 1968, the newspaper Washington Post wrote: "Her life was truly one of the most remark able phenomena of our time and her death just short of the age of 88 leaves the whole world poorer."

    Helen Keller was born on June 27th, 1880, in Tuscumbia, Alabama. For the first 19 months of her life, she was a pretty and happy baby, normal in every way. Then a sudden illness destroyed her sight and her hearing. Because she could not hear sounds to imitate(模仿), she could not speak. Helen used to say that her real birthday was not June 27th, 1880, but March 3rd, 1887—the day when Anne Sullivan entered her life. It was Anne Sullivan who taught Helen to spell certain words by a special system, Braille, and even to talk.

    Anne Sullivan could not teach Helen Keller to speak until some other important things had been learned. The little girl had to learn to control her actions and feelings. She had to learn that she could not always do what she wanted to do. She had always been able to get what she wanted by using force. The teacher had to change such habits without breaking the child's spirit.

    Miss Sullivan's battle began. Sometimes, there was real fighting between the wild child and the strong young teacher. At last, however, the battle was won by Miss Sullivan, who succeeded in showing Helen that she loved her and wanted to help her. The child and her teacher became friends. They continued to be friends until the teacher's death, fifty years later.

    The day on which Helen finally accepted Miss Sullivan as her friend and teacher was a great day in Helen's life. After that, the teacher could begin to teach the child language.

    A friend is better than fortune. A friend is worse than poison in some cases.

    The two sentences above have opposite meanings and seem to be unreasonable  but they can be explained as follows: the first refers to all good friends who drive us towards good while the second all bad ones who lead us into bad ways.

    My ideal friend is of course a good friend whose goodness is shown below — he has no bad habits  such as smoking and drinking. He lives in frugality (节俭). He studies hard so as not to waste his golden time. At home he honors his parents and loves his brothers; at school he respects his teachers and shares the feelings of his classmates. He treats those truly who are true to him. In a word, he has all the good characteristics that I don't have. I can follow him as a model. With his help I can be free from all difficulties.

    Indeed, if I have such a person as my friend, I shall never fear difficulty and I shall never know the existence of the word "failure".
