Mark Twain left school when he was twelve. He had little school education. In spite of (尽管) this, he became the most famous writer of his time. He made millions of dollars by writing. His real name was Samuel Langhorne Clemens, but he is better known all over the world as Mark Twain, his pen-name.

    Mark Twain was born in 1835 and he was not a healthy baby. In fact, he was not expected to live through the first winter. But with his mother's tender care, he managed to survive. As a boy, he caused much trouble for his parents. He used to play jokes on all of his friends and neighbors. He didn't like to go to school, and he constantly ran away from home. He always went in the direction of the nearby Mississippi (密西西比河). He was nearly drowned (淹死) nine times.

    After his father's death in 1847, Mark twain began to work for a printer, who only provided him with food and clothing. Then, he worked as a printer, a river-boat pilot and later joined the army. But shortly after that he became a miner. During this period, he started to write short stories. Afterwards he became a full-time writer.

    In 1870, Mark Twain got married. In the years that followed he wrote many books including Tom Sawyer in 1876, and Huckleberry Finn in 1884, which made him famous, and brought him a great fortune (财富).

    Unfortunately, Mark Twain got into debts in bad investments (投资) and he had to write large numbers of stories to pay these debts. In 1904, his wife died, and then three of their children passed away.

    At the age of 70, his hair was completely white. He bought many white suits and neckties. He wore nothing but white from head to foot until his death on April 21, 1910.

    There are about 5,000 different kinds of ladybugs(瓢虫)in the world. They are also known as lady beetles or ladybird beetles. They come in many different colors and patterns, but the best-known in North America is the seven-spotted ladybug, with its shiny, red-and-black body.

    In many cultures, ladybugs are thought to be good luck. Most people like them because they are pretty, lovely and do no harm to human beings. But farmers love them because they eat aphids and other plant-eating pests. One ladybug can eat up 5,000 insects in its lifetime!

    Most ladybugs have dome-shaped bodies with six short legs. Depending on the kind, they can have spots, stripes, or nothing at all. Seven-spotted ladybugs are red or orange with three spots on each side and one in the middle. They have a black head. Ladybugs are colorful for a reason. They tell the enemy: "Eat something else! I taste terrible." When threatened, they may play dead. Birds are ladybugs' main predators(天敌), but they are also eaten by frogs, spiders, and dragonflies.

    Ladybugs are happy in many different places, including grasslands, forests, cities, suburbs, and along rivers. Seven-spotted ladybugs are native to Europe but were brought to North America in the mid-1900s.

    Ladybugs are most active from spring until fall. When the weather turns cold, they look for a warm place to hibernate, such as in rotting logs, under rocks, or even inside houses. These hibernating places can have thousands of ladybugs.

    The name "ladybug" was given by European farmers who prayed to the Virgin Mary when pests began eating their crops. After ladybugs came and wiped out the invading insects, the farmers named them "beetle of Our Lady". This later was shortened to "lady beetle" and "ladybug".

    If you are in Dubai you may notice a robot police officer sharing the street with you. Your first thought might be, “Have I walked into a movie set？”

    The answer is no. That robot is Dubai's newest police officer. The robot has a touch screen instead of a gun. The robot will be employed mostly at shopping centers and other places popular with visitors.

    The robot's face has eyes but no mouth or nose. It stands 165 centimeters tall and weighs 100 kilograms. If the robot works well, Dubai says 25 percent of its police force could be robots by 2030. The robot cop(巡警) was officially presented at Dubai's Gulf Information and Security Expo and Conference in May.

    The police hope the robot will make life easier for the people of Dubai. Khalid Al Razooqi is Director General of Smart Services at the Dubai Police. He said the robot can help the public every day, and that “it won't ask for any sick leave”.

    The robot cannot make arrests (逮捕). But it can recognize faces and compare them to photographs on a criminal database. It can also sense emotions. People can use the robot's touch screen to do things like reporting a crime, paying fines and reporting lost or found things. They can also ask how to get somewhere. The robot can greet and shake hands with people. So far, the robot can speak Arabic and English. It soon will learn other languages such as Russian, Chinese, French and Spanish. In addition to having a touch screen, the robot has a camera that can live stream video to a police command center.

    Dubai has plans to add other kinds of robots to its police force. Within two years, the city plans to use a three meter tall robot that can run up to 80 kilometers an hour. The Dubai government says the machine would be the world's largest robot. A human police officer will be able to sit inside and control the robot. It will be able to lift heavy objects.

    The city also plans to use an egg shaped robot to control parking areas and give tickets to people who break traffic laws.

    It happened to me recently. I was telling someone how much I had enjoyed reading Barack Obama's Dreams From My Father and how it had changed my views (观点）of our President. A friend I was talking to agreed with me that it was, in his words, "a brilliantly (精彩地) written book". However, he then went on to talk about Mr. Obama in a way which suggested he had no idea of his background at all. I sensed that I was talking to a book liar.

    And it seems that my friend is not the only one. Approximately two thirds of people have lied about reading a book which they haven't. In the World Book Day's “Report on Guilty Secrets”. Dreams From My Father is at number 9. The report lists ten books, and various author: which people have lied about reading, and as I'm not one to lie too often (I'd hate to be caught out), I'll admit (承认) here and now that I haven't read the entire (全部的) top ten. But I am pleased to say that, unlike 42 percent of people, I have read the book at number one, George Orwell's 1984.I think it's really brilliant.

    The World Book Day report also has some other interesting information in it. It says that many people lie about having read Jane Austen, Charles Dickens, Fyodor Dostoevsky (I haven't read him, but haven't lied about it either) and Herman Melville.

    Asked why they lied, the most common reason was to "impress"（使留下深刻印象) someone they were speaking to. This could be tricky if the conversation became more in-depth!

    But when asked which authors they actually enjoy, people named J. K. Rowling, John Grisham, Sophie Kinsella (ah, the big sellers, in other words). Forty-two percent of people asked admitted they turned to the back of the book to read the end before finishing the story (I'll come clean: I do this and am astonished that 58 percent said they had never done so).

    I have been passionate about sewing and fashion design since I was 12. Two years ago, I designed and made a set of outfits from recyclable materials for a charity fashion show. Through this highly meaningful and profound experience, I became sensitized to the importance of protecting and preserving our environment when designing and making fashion items, resulting in my founding an organization to promote eco-friendly design and fashion.

    My interest has led me to research areas of fashion that have environmental implications. For example, some popular clothing stores have announced merchandizing policies designed to improve the environment. For those of us who are eco-conscious, it is incumbent upon us to evaluate whether such policies are just a marketing ploy, or represent genuine efforts to protect our environment.

    Three chain-stores, H&M, Urban Outfitters and Forever 21, have been promoting "green" items. After I examined their products, I have concluded that H&M and Urban Outfitters are truly helping the environment with their efforts, while Forever 21 seems to be using the 'go green' trend as a way to sell more products, rather than genuinely help the environment.

    Of these three stores, H&M has the most extensive eco-fashion plans. It is already well on its way to implementing its plans by increasingly blending organic cotton into their garments, as well as putting fully organic cotton items on the market. The store also belongs to the Organic Exchange Organization, which endorses growth of organic cotton. To reduce the substantial harm from non-organic cotton production, H&M is involved with the Better Cotton Initiative. Mindful of the adverse effects of climate change, the store aims to minimize transportation and energy usage. H&M labels their eco-friendly products with an official symbol, the Flower, to represent a production system that is less harmful than most traditional processes. Because of these actions and policies, H&M is already well on its way to making a difference on the environment.

    With its Urban Renewal brand, Urban Outfitter takes a different approach from H&M in promoting eco-friendly fashion. The brand features women's apparel made from strictly environmentally-friendly sources, such as vintage, dead stock, or surplus clothing. Urban Renewal produces fashionable garments, and embraces being eco-friendly through recycling.

    Unlike the other two stores above, Forever 21's eco-fashion efforts fall short; a cynic would say their message is downright misleading. It promotes the "'green" image, and yet many of their supposed eco-friendly products do not help the environment. For example, it sells a "Think Green Tote" that, according to the site, is meant "to send an environmentally friendly message". However, it is made of 100% non-organic cotton which is one of the most damaging fabrics to the environment, mostly because it requires greater chemical intervention compared to organic cotton. Also, the "I Love My Planet Tote" is supposed to "make a positive statement," but is also made of 100% cotton that is not organic. The only tote that is environmentally-friendly is the "H81 Organic Cotton Tote" from Forever 21's Heritage brand, made from 100% organic cotton. Now that Forever 21 has portrayed itself as being "green," it should start "walking the walk."
