People have been making and flying kites for about 2,000 years. {#blank#}1{#/blank#}Some historians believe it the ancient Chinese may have started kite flying 2000 years ago. It is still a popular hobby in China, Japan and Korea and in other countries of the Far East where beautifully decorated appear in different colors.

    {#blank#}2{#/blank#}Simple kites are made by crossing two sticks and covering them with paper or cloth. Then you attach a string at the end. More expensive kites have frames made of fiberglass, plastic or aluminum. The name comes from a graceful bird called kite.

    {#blank#}3{#/blank#}A flat kite is the oldest and simplest type of kite.  It flies because air flows over and under the kite's wing. The pressure under the wing helps the kite lift into the air.

    {#blank#}4{#/blank#}Early scientists sent kites up into the air to measure temperature at different heights. In 1752, Benjamin Franklin used a kite to prove that lightning was a form of electricity. He attached a metal key to the string of a kite. When lightning hit the kite, electricity passed down the string and Franklin got an electric shock. It was a very dangerous experiment that you shouldn't copy.

    Kites were also used to develop airplanes. The Wright Brothers experimented with kites before they flew the first airplane. {#blank#}5{#/blank#} In World War I the Germans developed a large kite that could transport people to a submarine. Kites were also used to carry radio signals over long distances.

    Today most people fly kites as a hobby. Kite festivals are organized in many cities in all parts of the world.

A. Kites are made in many different sizes, colors and shapes.

B. flying kites is great fun and it is easy if you know some secrets.

F. Stories of kites were brought to Europe till the end of the 13^th century.

    It used to be a matter of fact when Peter Pan-a character from James Matthew Harrie's 1911 book-said: “All children, except one, grow up.”

    But this “fact” doesn't seem to apply to today's world anymore.

    According to the NPD Group, a US market research company, sales of toys to adults in the UK increased by more than 20 percent in 2016, three times the pace of the children's toy market itself. These toys varied from puzzles and Lego building sets to vehicle models and action figures. And more than half of the sales came from millennials-people born between the 1980s and 2000s.

    “Adults of the 21st century are channeling their inner child, one toy at a time,” commented website Koreaboo. This is also why these adults are sometimes looked to as “kidults”.

    According to Frederique Tutt, an analyst at NPD, the motivation of these grown-ups is to escape the stress of today's fast-paced world. They are driven toward the more immediate pleasures brought by toys than those brought by, say, getting a promotion, which is far less easy to achieve.

    “It reminds me of the playful side of life,” Rob Willner, a 25-year-old PhD student in the UK, told The Telegraph when talking about his love for Lego, which he said brings him both comfort and pleasure.

    Despite this, some social scientists see the trend as disturbing. To Frank Furendi, a professor at the University of Kent in the UK, the fact that so many adults are seeking “the excitement of youth” is the evidence that “adulthood has got nothing attractive about it anymore”, he told The New York Times. “That's actually quite sad.”

    But scientists are probably just worrying too much. According to Canadian comic book artist Todd McFarlane, collecting toys could simply be a way for people to express their individuality. “It's just pop culture stuff. It's stuff that says, ‘I like a little of this and I like a little of that',” he told ABC News. “It's no big deal.”

    So now that over 100 years have passed since Peter Pan, perhaps it's time to introduce a new “fact”, as stated in the tagline(标语) of the UK fashion brand KIDULT: “Growing old is mandatory (被迫的), but growing up is optional.”

    Getting rid of dirt(灰尘), in the opinion of most people, is a good thing. However, there is nothing fixed about attitudes to dirt.

    In the early 16th century, people thought that dirt on the skin was a way to block out disease, as medical opinion had it that washing off dirt with hot water could open up the skin and let illnesses in. A particular danger was thought to lie in public baths. By 1538, the French king bad closed the bath houses in his kingdom. So did the king of England in 1546. Thus it began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.

    Though the belief in the merit of dirt was long-lived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War ll. Advertisements repeatedly sell the idea: clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?

    Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warm(警告)their children of touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an American immunologist(免疫学家), encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.

    The annual World Economic Forum (经济论坛) took place in Davos, Switzerland, in Jan. 23-26, 2018. What did Chinese entrepreneurs (企业家) speak in the forum? Are there some quotable quotes for you?

    Jack Ma, founder and executive chairman of Alibaba Group

    "I think globalization cannot be stopped — no one can stop globalization, no one can stop trade. If trade stops, the world stops. Trade is the way to dissolve (溶解，结束) the war not cause the war," said Ma in Davos, "Google, Facebook, Amazon and Alibaba — we are the luckiest companies of this century. But we have the responsibility to have a good heart, and do something good."

That's the topics of the Davos this year. I think a very important thing in business is cooperation. If we can unite, work together, if we work very closely, I think we can bring more hope to the people and we can build more trust between the people, countries and companies and partners," he said.

    Jane Sun, CEO of Ctrip

    "Tourism is a sunrise industry. Since I entered Ctrip, every year there are new comers, which, first of all, shows that tourism is booming." Sun told Sina.com in Davos. "We invested heavily in ABC. A refers to AI, B is big data, and C is cloud computing. As we continue to expand overseas, these three will be very good weapons for us. So we think those mean opportunity," she said.

    Hu Xiaoming, president of Aliyun

    "In 2018, people will see the development in various countries more closely connected with cloud computing. More manufacturing enterprises and financial institutions will start to use 'cloud', and cloud computing will increase the efficiency of technology and finance," Hu told Xinhua in Davos.

    Elizabeth Blackwell was born in England in 1821, and moved to New York City when she was ten years old. One day she decided that she wanted to become a doctor. That was nearly impossible for a woman in the middle of the nineteenth century. After writing many letters asking for admission(录取) to medical schools, she was finally accepted by a doctor in Philadelphia. She was so determined that she taught school and gave music lessons to get money for the cost of schooling.

    In 1849, after graduation from medical school, she decided to further her education in Paris. She wanted to be a surgeon(外科医师), but a serious eye problem forced her to give up the idea.

    Upon returning to the United States, she found it difficult to start her own practice because she was a woman. By 1857 Elizabeth and her sister, also a doctor, along with another woman doctor, managed to open a new hospital, the first for women and children Besides being the first woman physician and founding her own hospital, she also set up the first medical school for women.
