For centuries, elephants have played a big role in the world's economies, culture and religion. The African elephant used to be found all over Africa and the Asian elephant moved from Syria to China to Indonesia. Nowadays, elephants are found in small groups in the south of the Sahara Desert and scarcely in Southeast Asia, Sri Lanka and India.

    In the early twentieth century, there were close to ten million elephants, and now the elephant number is as low as 252,000 and expected to drop down to 160,000 by 2025. Between 2007 and 2014, the elephant population fell by at least 30%, or 144,000 elephants. As researchers have traveled over the African plains, they only spotted one herd of 36 elephants in an area like the size of Mexico. It is clear that these gentle mammals are disappearing right before our eyes.

    There are many reasons why the elephant population has been decreasing, one of which is their habitat. Humans are competing with elephants for living space, and as more and more humans clear the land that is being used by elephants, the elephants have less space. Elephant hunting or “poaching” has been a major factor for the disappearance of this species, and they are killed only for their valuable ivory tusks. Although the trade of tusks is illegal, it is still a common practice in many places.

    Often, all the local people living among elephants would be farmers, and found that they could make more money by selling the tusks of one elephant, than doing manual labor for twelve years. That alone makes it really hard to prevent them from killing the elephants.

    Some places such as Botswana, have put in extra effort to protect their wildlife from poachers by founding their Botswana Defense Force, which is made up of around 700 specially-trained soldiers that are stationed in 40 different areas.

    Alex Elman runs a big business—something hard to imagine after she lost her sight in her twenties. But Elman says that losing her sight helped her focus on finding success.

    Elman's father planted a hillside vineyard(葡萄园)in western Massachusetts in 1981. It's where Elman spent the darkest period of her life. When she was 27 years old, she went blind as a result of diabetes(糖尿病) 17 years ago. She recalled，“I hid in my home. I hid in the place，to me, that was the safest place in the world.”

    However, she found a new way forward.

    Elman is the founder of Alex Elman Wines, a growing competitor of organic wines from all around the world: Chianti from Italy, Torrontes from Argentina.

    Elman's isn't solitary in her work. Instead, she has a good assistant, a guide dog named Hanley. Hanley is something of a professional wine taster and travels to all of the wine factories that Elman runs, from South America to Europe.

    At first, Elman wouldn't accept a guide dog. Now it's hard to imagine her life, or her business, without him. She said, "When someone tells me something is organic and I don't really believe it because I taste something funny on it, m put it in front of his face and if he likes the wine, he'll actually go in and sniff it. If if s not right, he'll turn his head away. That's how we know whether the soil is actually organic.”

    Elman believes the loss of her sight was a gift from God. She said, “It allowed me to pay attention to what I thought was important. Therefore, adapt to a situation, and you'll be all right. Because you can't change it anyway, right?”

    All over the world people enjoy sports. Sports help to keep people healthy, happy and help them to live longer.

    Sports change with the seasons. People play different games in winter and summer.

    Games and sports often grow out of people's work and everyday activities. The Arabs use horses or camels in much of their everyday life; they use them in their sports, too.

    Some sports are so interesting that people everywhere go in for them. Football, for example, has spread around the world. Swimming is popular in all countries near the sea or in those with many rivers.

    Some sports or games go back thousands of years, like running or jumping. Chinese boxing, for example, has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet. People are inventing new sports or games all the time.

    People from different countries may not be able to understand each other, but after a game they often become good friends. Sports help to train a person's character. One learns to fight hard but fight fair, to win without pride and to lose with grace.

    The printing press has a long history. It was invented in Germany by Joannes Gutenberg around 1440, and brought to England by William Caxton in the 1470s.Yet the basic technology of printing remained the same up to the end of the 18th century, requiring two men to operate a wooden screw press by hand, producing about 200 impressions an hour. The 19th century was the period in which this process was mechanised, automated, and made many times faster.

    A key moment in the development of mass newspapers was the development of the steam-powered printing press, adopted by the times in 1814. The new presses were able to print per hour around five times the number produced by the machines. The editor, John Walter, had the machines fixed secretly at night, so that when his printers reported for duty the next morning the majority of them found that they were out of work. The Times went from a circulation of 5,000 a day in 1815 to around 50,000 in the middle of the century. This was not caused by the steam press, but neither could it have happened without it.

    Later developments improved this effect: the Applegath machine achieved 5,000 impressions per hour, and the Hoe press, an import from the United States, reached to 20,000 impressions per hour. Increase in the speed of papermaking in this period brought down the cost of printed materials both for the producer and the customer. In 1896, the Daily Mail was sold at the cost of only half a penny, and by 1900 it was selling nearly 1,000,000 copies a day.

    If print production was completely changed in those years, then so was its distribution. The appearance of the steam railway meant that for the first time newspapers could be distributed across the country on a daily basis.

    I was ten when my father first sent me flowers. I had been taking ballet lessons for four months, and the school was giving its yearly performance. As a member of the beginners' chorus group, I was surprised to hear my name called out at the end of the show along with the leading dancers and to find my arms full of red roses. I can still feel myself standing on that stage, seeing my father's big smiles.

    Those roses were the first of many bunches accompanying all the milestones in my life. Getting all those roses was wonderful, but they brought a sense of embarrassment. I enjoyed them, but I also felt they were too much for my small achievements.

    Not for my father. He did everything in a big way. Once, when mother told him I needed a new party dress, he brought home a dozen. His behavior often left us without money for other more important things. Sometimes I would be angry with him.

    Then came my 16th birthday. It was not a happy occasion. I was fat and had no boyfriend. And my well-meaning father furthered my suffering by giving me a party. As I entered the dining room, there on the table next to my cake was a huge bunch of flowers, bigger than any before.

    I wanted to hide. Now everyone would think my father had sent flowers because I had no boyfriend to do it. Sweet 16, and I felt like crying. But my best friend, Jenny, whispered, "Boy, you're lucky to have a father like that."

    As the years passed, other occasions—birthdays, awards, graduations—were marked with Dad's flowers. Those flowers symbolized his pride, and my success. As my fortunes grew, my father's health became worse, but his gifts of flowers continued until he died. I covered his coffin with the largest, reddest roses I could find.

    Often during the dozen years since, I felt an urge to buy a big bunch to fill the living room, but I never did. I knew it would not be the same.

    Then one birthday, the doorbell rang. I was feeling blue because I was alone. My husband and my two daughters were away. My 10-year-old son, Tommy, had run out earlier with a "see you later". So I was surprised to see Tommy at the door. "Forgot my key," he said. "Forgot your birthday too." He pulled a bunch of roses from behind his back.

    "Oh, Tommy," I cried. "I love flowers!"
