    A GAME AS ENGLISH AS CROQUET(槌球游戏)，by Anna Young in Room 218. First, we will look at the origins of croquet, a much loved garden game in England. We will look at simple croquet rules, and then practice time! We'll go out and play!

August 4th

    WHY ENGLISH PEOPLE LAUGH, by Jim Scrivener in Room 117. Let me try to show you a little bit of what British people find funny. You will discover some of the most popular radio& TV comedy game shows. You probably won't find it funny at all! But you will learn a bit more about us Brits!

    A family story is like a puzzle. Each family member leaves some clues. Family members come together because they have a common tie with one another, sharing a name and special traditions. Exploring family roots and sharing past memories ensure each tradition lives on.

    Ancestory.com has created customized (订做的) “Our Name is History” books to give your family a look into your history by learning about your last name. By visiting it, you can check if information is available for your last name. Ancestory.com researchers have collected more than 5 billion names from records such as passenger lists, immigration records and from birth, marriage and death records. The collected information is then used for each customized book.

    “Our Name is History” books are available for nearly 200,000 last names, accounting form 85 percent of all the US homes. The collected information is a great start of learning about your family roots. This book will not only surprise your mother, but also become a precious memory to pass down through the generations. It can also be an inspiration for her to talk about all the special women in her life.

Life in the Clear

Transparent animals let light pass through their bodies the same way light passes through a window. These animals typically live between the surface of the ocean and a depth of about 3,300 feet—as far as most light can reach. Most of them are extremely delicate and can be damaged by a simple touch. Sonke Johnsen, a scientist in biology, says, "These animals live through their life alone. They never touch anything unless they're eating it, or unless something is eating them."

And they are as clear as glass. How does an animal become see-through? It's trickier than you might think.

    The objects around you are visible because they interact with light. Light typically travels in a straight line. But some materials slow and scatter (散射) light, bouncing it away from its original path. Others absorb light, stopping it dead in its tracks. Both scattering and absorption make an object look different from other objects around it, so you can see it easily.

    But a transparent object doesn't absorb or scatter light, at least not very much. Light can pass through it without bending or stopping. That means a transparent object doesn't look very different from the surrounding air or water. You don't see it you see the things behind it.

    To become transparent, an animal needs to keep its body from absorbing or scattering light. Living materials can stop light because they contain pigments (色素) that absorb specific colors of light. But a transparent animal doesn't have pigments, so its tissues won't absorb light. According to Johnsen, avoiding absorption is actually easy. The real challenge is preventing light from scattering.

Animals are built of many different materials—skin, fat, and more—and light moves through each at a different speed. Every time light moves into a material with a new speed, it bends and scatters. Transparent animals use different tricks to fight scattering. Some animals are simply very small or extremely flat. Without much tissue to scatter light, it is easier to be see-through. Others build a large, clear mass of non-living jelly-like (果冻状的) material and spread themselves over it.

    Larger transparent animals have the biggest challenge, because they have to make all the different tissues in their bodies slow down light exactly as much as water does. They need to look uniform. But how they're doing it is still unknown. One thing is clear: for these larger animals, staying transparent is an active process. When they die, they turn a non-transparent milky white.

    I am astonished at the way God knows when to send a special gift of encouragement at just the right time! It might be in a dream, a lost letter, a memory, or something found that we'd forgotten about.

    My grandmother was from a town in Michigan. And summer after summer I enjoyed staying with my grandparents as a young child. I was from the city and loved the small town where they lived. People knew everyone, their children, their pets, their ancestors.

    Grandma was always using her hands for something exciting …She would make sandwiches and we'd have tea parties, plant flowers and carefully tend them. She loved knitting sweaters as well as making beautiful quilts　for her grandchildren. I remember the small thimble ( 顶 针 ) she would place on her finger while doing her needlework.

    A few years ago, when Grandma left this earth for her new residence in Heaven, I bid farewell to my loving grandmother. How quickly our lives can change! We had just had tea together a couple of months earlier, on her 91st birthday. I missed her very much, but I noticed it mostly on my birthdays, because there was no card from Grandma. She'd never forgotten my birthday!

    On one particular birthday when I was feeling a little low, something happened and made me feel as if she was sharing that special day with me. I was arranging some colorful pillows that she had made, and suddenly I felt something inside one pillow; it was small and hard. I moved the object to a seam (缝) that I carefully opened, and, to my delight, out came a tiny silver thimble!

    How happy I was to find something that had been a part of her! Not realizing k had fallen off her finger, I pictured her sewing h into that little pillow that I just happened to fluff (抖松), to place on my bedspread (床罩) that day. I carefully laid the thimble alongside the others Id collected over the years. What a precious memory of a very special lady who, somehow, I knew, was laughing in delight at sewing her thimble into my pillow. I heated the kettle and made some tea, using my best china, as Grandma always did, and then enjoyed my tea and Grandma's thimble. What a wonderful birthday that was!

    Three men traveling on a train began a conversation about the world's greatest wonders.

    "In my opinion, "the first man said, "the Egyptian pyramids are the world's greatest wonder. Although they were built thousands of years ago, they are still standing. And remember: the people who built them had only simple tools. They did not have the kind of machinery that builders and engineers have today."

    "I agree that the pyramids in Egypt are wonderful," the second man said, "but I do not think they are the greatest wonder. I believe computers are more wonderful than the pyramids. They have taken people to the moon and brought them back safely. In seconds, they carry out mathematical calculations that would take a person a hundred years to do."

    He turned to the third man and asked, "What do you think is the greatest wonder in the world?"

    The third man thought for a long time, and then he said, "Well, I agree that the pyramids are wonderful, and I agree that computers are wonderful, too. However, in my opinion, the most wonderful thing in the world is this thermos."

    And he took a thermos out of his bag and held it up.

    The other two men were very surprised. "A thermos?" they exclaimed. "But that's a simple thing."

    "Oh, no, it's not," the third man said. "In the winter you put in a hot drink and it stays hot. In the summer you put in a cold drink and it stays cold. How does the thermos know whether it's winter or summer?"

    In 1800, only three percent of the world's population lived in cities. Only one city — Beijing — had a population of over a million. Most people lived in rural areas, and never saw a city in their lives. In 1900, just a hundred years later, roughly 150 million people lived in cities, and the world's ten largest cities all had populations exceeding one million. By 2000, the number of city dwellers exceeded three billion; and in 2008, the world's population crossed a tipping point — more than half of the people on Earth lived in cities. By 2050, that could increase to over two-thirds. Clearly, humans have become an urban species.

    In the 19th and early 20th centuries, many people viewed cities negatively — crowded, dirty environments full of disease and crime. They feared that as cities got bigger, living conditions would worsen. In recent decades, however, attitudes have changed. Many experts now think urbanization (城市化) is good news, offering solutions to the problems of Earth's growing population.

    Harvard economist Edward Glaeser, author of The Victory of the Cir, is one such person. Glaeser argues that cities are very productive because "the absence of space between people" reduces the cost of transporting goods, people, and ideas. While the flow of goods has always been important to cities, what is most important today is the flow of ideas. Successful cities enable people to learn from each other easily, and attract and reward smart people with higher wages.

    Another urbanization supporter is environmentalist Stewart Brand. Brand believes cities help the environment because they allow haft of the world's population to live on about four percent of the land. This leaves more space for open country, such as farmland. City dwellers also have less impact per person on the environment than people in the countryside. Their roads, sewers, and power lines need fewer resources to build and operate. City apartments require less energy to heat, cool, and light. Most importantly, people in cities drive less so they produce fewer greenhouse gases per person.

    So it's a mistake to see urbanization as evil; it's a natural part of development  The challenge is how to manage the growth.
