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.

    Happy And Other Bad Thoughts by Larry Doyle (Ecco, $ 14.99)

    The meaning of silence varies among cultural groups. Silences may be thoughtful, or they may be empty when a person has nothing to say. A silence in a conversation may also show stubbornness, uneasiness, or worry. Silence may be viewed by some cultural groups as extremely uncomfortable; therefore attempts may be made to fill every gap (间隙) with conversation. Persons in other cultural groups value silence and view it as necessary for understanding a person's needs.

    Many Native Americans value silence and feel it is a basic part of communicating among people, just as some traditional Chinese and Thai persons do. Therefore, when a person from one of these cultures is speaking and suddenly stops, what maybe implied (暗示) is that the person wants the listener to consider what has been said before continuing. In these cultures, silence is a call for reflection.

    Other cultures may use silence in other ways, particularly when dealing with conflicts among people or in relationships of people with different amounts of power. For example, Russian, French, and Spanish persons may use silence to show agreement between parties about the topic under discussion. However, Mexicans may use silence when instructions are given by a person in authority rather than be rude to that person by arguing with him or her. In still another use, persons in Asian cultures may view silence as a sign of respect, particularly to an elder or a person in authority.

    Nurses and other care-givers need to be aware of the possible meanings of silence when they come across the personal anxiety their patients may be experiencing. Nurses should recognize their own personal and cultural construction of silence so that a patient's silence is not interrupted too early or allowed to go on unnecessarily. A nurse who understands the healing (治愈) value of silence can use this understanding to assist in the care of patients from their own and from other cultures.

    Whenever we see a button, we are eager to press it because we know something will happen. This is true in most cases, for example on a doorbell and on the "on/off" button on the TV. But some buttons are actually fake, like the "close" button on a lift.

    Many people are in the habit of pressing the "close" button because they don't have the patience to wait for the lift doors to shut. But lifts "close" buttons are a complete scam, at least in the US-the doors will not close any faster no matter how hard you press.

    It started in the 199os when the Americans with Disabilities Act was passed in the US, making sure that all lifts stayed open long enough so that people with disabilities could enter. Only US firefighters and repairmen can use the buttons to speed up the door-closing process if they have a code or special keys.

    But to normal lift riders, the buttons aren't completely useless. According to psychologists, fake buttons can actually make you feel better by offering you a sense of control." Perceived（能够感知的）control is very important. It reduces stress and increases well-being," Ellen J. Langer, a psychology professor, said," Having a lack of control is associated with depression."

    Experts have revealed that a lot of buttons that don't do anything exist in our lives for this same purpose. For example, many offices in the US have fake thermostats（温度调节器）because people tend to feel better when they think they can control the temperature in their workspace.

    But psychologists found it interesting that even when people are aware of these little" white lies", they still continue to push fake buttons because as long as the doors eventually close, it is considered to be worth the effort.

   "That habit is here to stay," John Kounios, a psychology professor, said," Even though I have real doubts about the traffic light buttons, I always press them. After all, I've got nothing else to do while waiting.  So why not press the button in the hope that this one will work?"

    The Wizard and the Prophet: by Charles C. Mann. Knopf, 2018（$28. 95）

    The human population is moving toward 10 billion—some experts think we'll nearly hit that mark by 2050. How will the earth feed, house and otherwise support such a crowd？Environmental thinkers usually fall into one of two camps: those who prefer conservation and controlling consumption, like William ems, Norman Borlaug, for example, Writer Mann carefully record the lives and thought of the founder of these two philosophies.

    A Lab of One's Own: by Patricia Fara. Oxford University Press, 2018($24. 95)

    In World War I many women in the U. K. replaced their aprons with chemical suits and stepped into previously male-only fields of science, where they led war research efforts. Science historian Fara illustrates the lives of many of these forgotten women. Although the era marked a major step forward for women scientists, many worked for small wages in an environment of discrimination. In the nearly 100 years since, women have come a long way, Fara writes, but the glass ceilings remain solid and the pipelines leaky.

    Atom Land: by Jon Buterworth. The Experiment, 2018（319. 95）

    Butterworth takes readers on an amusing journey through the unknown OMS world of particle（粒子）physics. The first stop is "Atom Land," where Butterworth explains how electrons, protons and neutrons come together to build up everything we know. As the journey unfolds, we learn about lesser-known particles. Thankfully, our ship is equipped with tools such as mathematical equations（方程式）and a "laser light" that lights up the darkest of concepts.

    I've been really lucky this year. Not only did I have the opportunity to live in France, but I was able to see some other countries with my girlfriend. Now she is studying in Essen, a large city in Western Germany. I recently went to stay with her—it was my first visit to Germany! Essen is a very large city. It has all the conveniences of any large city so I felt immediately at home. I loved the variety of shops, restaurants, shopping malls, cocktail bars, nightclubs, parks and even a lake. There is also a city­wide network of trams, which makes getting around a piece of cake!

    I found the people to be really friendly, and most Germans speak very good English which made life easy for me. I was surprised by the casual attitude to alcohol in Germany, where it seems normal for people to drink beer on the street, or on the tram. My girlfriend and I visited two famous local cities, Düsseldorf and Cologne, which are both on the Rhine River. Düsseldorf is an urban metropolis with a great variety of restaurants. We took a boat tour on the river and went up the Rhine Tower, a really tall building which offers great views across the city. Cologne, as you might know, is world-famous for its perfumes. The cathedral there is an unmissable landmark. We made the effort to climb to the top of one of the cathedral's towers. The spiral (螺旋的) stairs seemed endless, but it was worthwhile for the impressive sights from the top.

    We also went in a cable car over the river and tasted a German delicacy called "Spaghettieis" which is ice cream with strawberry sauce! I also got to try the famous German sausage. I must admit, I really enjoyed the food! The only disappointment was the grey and rainy weather, which proves that Britain does not have the worst weather in Europe!
