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.

C. Kites have also been used in experiments.

D. No one knows for sure who invented the kite.

E. In Japan families fly fish kites on Children's Day, May5th.

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

G. In the past, kites were sometimes used to take pictures in wars.

    Some of the best things in life don't happen until you grow old enough to recognize them. I can say that about tea.

    I didn't start to drink tea until I was 35. What happened before that? The first time I felt a genuine urge to drink tea was in 2003, when I stayed briefly in the United Kingdom. After a time of consuming local food, I started to really like strong black tea. Although it was too strong to my tongue, I felt it was a necessity because it was comforting to my body.

    I took packs of green teas with me as gifts but was disappointed to find my British friends preferred much stronger black teas from Sri Lanka. Later I learned that although people know China for its teas, it ranks only third among the world's black tea exporters, after Sri Lanka and Kenya.

    After I came back to China and started to cover food stories, I met friends in the tea-drinking circle and learned more. Although the majority of the rest of the world drinks black tea, which the Chinese call“red tea”, China produces and drinks mostly green teas.

    I feel lucky to be Chinese because of the great variety of teas available in the country. It is estimated that there are more than 2,000 teas in China if you divide them geographically, including more than 600 locally famous brews. A more simple way to categorize (分类) is by color and extent of fermentation (发酵). That comes down to six main categories—green, white, yellow, dark-greenish (oolong), red and black teas.

    Tasting teas can be compared to our lives. They can be plain and predictable but sometimes they are full of pleasant surprises. Occasionally they can even seem too good to be true. The best thing is, you know there's always more to explore.

    Although one might not think so as a result of the disadvantages, thousands and thousands of ads have shown advertising is of great importance to the society in which people live, either in the United Kingdom, or in many other parts of the world .Advertising is necessary as a means of communicating with others, of telling them about the goods and services that are offered, and of which most of them would never get to hear at all if it were not for advertising. And advertising does a great deal to a rising standard of living conditions.

    In talking about advertisement, one should not think only a commercial on television, or an advertisement in the newspaper or magazines and—in the sense of communication—even the spoken or written words of salesmen. After all, the roots of advertising are to be found in the market place in the ancient times.

    For many years it was thought that it was not enough to just produce goods and supply services. It is only more recently that people came to understand the production of goods would be a waste of resources unless those goods can be sold at fair price within a reasonable time period. In the competitive society in which we live, it is very important that we go out and sell what we have to offer, and advertising plays an important part, whether selling at home or in export market. Around 2 percent of the UK national product is spent on advertising. But it must be thought that this advertising tries to sell goods to customers who do not buy them. Of course, advertising does try to catch the eyes of the buyer, but if the product one has bought does not match what the advertisement had described, it is extremely unlikely that the goods will sell well.

    As I was thinking about language learning the other day, the image of baking bread came into my mind. I compared some of the exercises and drills that we put ourselves through in order to learn a language to the various ingredients that go into baking a loaf of fresh bread.

    Real language learning takes place in human relationships. No one sits down and eats a cup of flour, even if he is hungry and in a hurry. You don't become bilingual（双语的）by learning lists of vocabulary. You don't become a speaker of a language by memorizing verb conjugations（动词的词形变化）and agreement rules. You become bilingual by entering a community that uses that other language as its primary means of communication.

    I am not suggesting that we can make bread without ingredients. Flour is necessary, as are yeast, salt, water and other ingredients. Vocabulary is part of any language and will have to be learned. Grammatical rules exist in every language and cannot be ignored. But merely combining the appropriate ingredients in the recommended proportions does not result in bread. At best, you only end up with a ball of dough（面团）.

    In order to get bread, you have to apply heat to the dough. And in language learning, that heat comes from the community. Anyone who has learned a second language has experienced that heat. It creeps up your neck when you ask the babysitter, “Have you already been eaten?” when you meant to say, “Have you already eaten?” When you try to say something quite innocent and the whole room bursts into laughter, you are experiencing the heat that turns raw dough into good bread.

    Remember the old saying, “If you can't stand the heat, get out of the kitchen”? This is where language learning often breaks down because we find the heat uncomfortable and we stop the baking process. In other words, we can't stand the heat, so we get out of the kitchen.

    However, the language learner who stays in the kitchen—in the heat—until the combined ingredients are thoroughly transformed will enjoy the richness of a quality loaf of bread. He said that he did not “get out of the kitchen” at the critical moment when the oven seemed too hot. The dedicated language learner knows that becoming bilingual cannot be achieved without the heat!

    Photography（摄影） is a very popular art form. Anyone with a camera – or a mobile phone – can practice it. A picture communicates in a way that words often can't. As the photographer Destin Sparks put it, “Photography is the story I fail to put into words.” And there's no better chance to practice the art of photography than during our vacation time.

    Holiday photos have been a part of the culture of travelers for a long time. For decades, vacationers have made sure they've packed a camera along with bathing suits, Hawaiian shirts and sunglasses. A camera is an important holiday item. But over the last 10 years, photography has become much more popular. It's easy to capture ( 捕捉 ) still and moving pictures of places of interest, and it's also easy to show off these pictures on social media. Armed with their smart phones, tourists, this year more than ever, are capturing the beauty of our planet.

    Of course, travel companies have caught on to this. Trekksoft has an example of photo-tourism from the United States, a land with a vast choice of beautiful locations. Antelope Slot Canyon Tours in Arizona specializes in tours of the state's famous canyons（峡谷）, which gives photographers the chance to capture them on camera.

    Most of the tourists are able to make beautiful images with just their mobile phones. Still, help is on hand from the tour guide for those who aren't great at using their cameras. These tour guides have taken a course in photography in case the skills they've learned would help their customers.

In early February 2019, 51-year-old Rainer Schimpf and his team set out to film South Africa's famous Sardine Run off the coast of Port Elizabeth. The migration of billions of South African sardines, is a big draw for hunters, especially seabirds and dolphins. The two species work together to herd the large group of fish into smaller shoals (浅滩), which are then eaten by not just the birds and the dolphins, but also sharks and Bryde's whales.

In an attempt to find the best scene of the amazing natural phenomenon, which has been the subject of many films, Rainer got into the middle of a swirling ball of fish. Suddenly the sea churned (翻腾), and the experienced diver and his photographer Heinz Toperczer, who was filming from the boat, instantly realized something strange was going on.

Toperczer later said, "As Rainer moved towards the shoals, suddenly the water churned widely up, dolphins shot out of the water and then a whale appeared and caught him!"

Rainer, who was swallowed in darkness inside the whale's mouth, was trying to survive. "I held my breath because I thought he was going to dive down and release me much deeper in the ocean," the diver said.

Fortunately for Rainer, the whale quickly realized he was no sardine! "I felt huge pressure around my waist (腰部) which is when I guess the whale realized his mistake," he said. "As the whale turned sideways, he opened his mouth slightly to release me, and I was washed out, together with tons of water, of his mouth." Though the entire event lasted just 1. 8 seconds, it felt like a century to Rainer.

Still holding his underwater camera, the diver swam to his boat, where he was quickly rescued by the members of the team. The terrifying adventure did not worry Rainer for too long. After checking to ensure he had no injuries, the diver returned to the water. Fortunately, the rest of the adventure went peacefully.
