Mark Twain was a great writer. He was from the USA. He was born in 1835. He was also a famous speaker. He was famous for his sense of humour. Many people liked to listen to him talk because he liked to tell some interesting stories to make people laugh all the time.

    One day Mark Twain was going to a small town because of his writing. Before he was going to leave, one of his friends said to him that there were always a lot of mosquitoes in the town and told him that he'd better not go there. Mark Twain waved (摇动) his hand and said, “It doesn't matter. The mosquitoes are no relatives of mine. I don't think they will come to visit me.”

    After he arrived at the town, Mark Twain stayed in a small hotel near the station. He went into his room, but when he was just about to have a rest, quite a few mosquitoes flew about him. The waiters felt very sorry about that. “I'm very sorry, Mr Mark Twain. There are too many mosquitoes in our town.” One of them said to him.

    Mark Twain, however, made a joke, saying to the waiter, “The mosquitoes are very clever. They know my room number. They didn't come into the wrong room.” What he said made all the people present laugh heartily.

    But that night Mark Twain slept well. Do you know why? That was because all the waiters in the hotel were driving the mosquitoes away for him during the whole night.

    Old age may not sound exciting.But recent findings offer good news for older people and for people worried about getting older.Researchers found that people become happier and experience less worry after they reach the age of fifty.In fact，they say by the age of eighty­five，people are happier with their life than they were when they were eighteen years old.

    The findings came from a survey of more than three hundred forty thousand adults in the United States.The Gallup Organization questioned them by telephone in 2008.At that time，the people were between the ages of eighteen and eighty­five.The researchers asked questions about emotions like happiness，sadness and worry.They also asked about mental or emotional stress.

    Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study.His team found that levels of stress were highest among adults between the ages of twenty­two and twenty­five.The findings showed that stress levels dropped sharply after people reached their fifties.

    The study also showed that men and women have similar feeling patterns as they grow older.However，women at all ages reported more sadness，stress and worry than men.

    Researchers say they do not know why happiness increases as people get older.One theory is that，as people grow older，they grow more thankful for what they have and have better control of their feelings.They also spend less time thinking about bad experiences.

    Professor Stone says the emotional patterns could be linked to changes in how people see the world，or maybe even changes in brain chemistry.

    The researchers also considered possible influences like having young children，being unemployed or being single.But they found that influences like these did not affect the levels of happiness and well­being related to age.

    China now has 52 sites included on the UNESCO World Heritage list, which was established to safeguard unique and irreplaceable cultural and natural sites around the world. Let's have a look at some of them, which may give you some clues on your next travel plan.

    Mausoleum of the First Qin Emperor

    The Mausoleum of the First Qin Emperor is located in Lintong county, near Xi'an city, capital of Shaanxi province. A total of 8,000 life-size terracotta warriors, chariots and horses, and hundreds of bronze weapons have been unearthed from it. Many state leaders and experts worldwide believe that the discovery of the mausoleum is a major archeological find and can be called the eighth wonder of the world, paralleling Egypt's pyramids.

    Kulangsu, a Historic International Settlement

    Gulangyu Island, known in the local dialect as Kulangsu, is located on the entry of the Jiulong River, facing the city of Xiamen. The island was occupied by at least a dozen countries, including Great Britain, France and Japan. As a result, Western culture grew rapidly there in the 19th century, especially music. With such a harmonious blend of Western music and Eastern culture, Gulangyu is naturally referred to as the “island of music”. It is famous for its outstanding musicians and musical instruments.

    Qinghai Hoh Xil

    Hoh Xil, which means “beautiful girl” in Mongolian, is located in the north-eastern end of the Qinghai-Tibetan Plateau. Hoh Xil National Nature Reserve is China's largest and the world's third largest uninhabited area. Because of the high altitude and fierce weather, it is impossible for people to live there, and therefore, it is a paradise for wildlife and home to more than 230 species of wild animals including endangered species such as the Tibetan antelope, which is recognized as the National Class I Protected animal.

    Huangshan Mountain

    Huangshan, known as “the loveliest mountain of China”, lies in the south of Anhui province in eastern China. The scenic area covers 154 sq km, and is famous for its peaks, rocks, pines, clouds and springs. It also has a rich cultural heritage. Xu Xiake, a famous traveler of the Ming Dynasty (1368-1644), visited Huangshan twice, and described it in a poem, calling it the best of all mountains in China. Today it holds the same fascination for visitors, poets, painters and photographers.

    One form of social prejudice against older people is the belief that they cannot understand or use modern technology. Activities like playing computer games, going on the Net and downloading MP3s are only for the youngsters. Isn't it unfair that older people enjoying a computer game should be frowned（皱眉）upon by their children and grandchildren?

    Nowadays older people have more control over their lives and they play a full part in society. Moreover, better health care has left more people in their sixties and seventies feeling fit and active after retirement. Mental activity, as well as physical exercise, can contribute to better health. Playing computer games is a very effective way of exercising the brain.

    When personal computers were first introduced, most older people didn't believe they would ever familiarize themselves with it. Now computers have been around for a few generations and retired people have gradually become more relaxed about using them for fun. Gamers over 65 prefer playing puzzle games and card games. Kate Stevens, aged 72, says: 揑 find it very relaxing. It's not very demanding, but you still need to concentrate.”

    Another development that has favored 揼rey games? is a change in the type of videogames available on the market. There's a greater variety of games to choose from, including more intellectual and complex strategy（策略）and simulation（模拟）games. Internet Chess and Train Simulator are among the most popular of these. Train Simulator is based on real-world rail activities. Players can choose from a variety of challengers, such as keeping to a strict-timetable and using helper engines during a winter storm.

    Some people argue that 揼rey gamers? simply don't have the skills required for computer games, and that teenagers are better. This couldn't be further from the truth. Most computer games require the kind of analytical thinking that improves with practice, which means that the 揼rey gamers may well be far better than gamers half a century younger than them.

To make a feather shuttlecock, a piece of cloth wrapped around a coin {#blank#}3{#/blank#} (need). Through the coin hole you can stick some feathers, {#blank#}4{#/blank#} function is to delay the rising and falling of the shuttlecock.

There {#blank#}5{#/blank#} (be) a great number of variations in styles and methods of kicking. With one leg fixed on the ground, the shuttlecock is kicked by the inner ankle of {#blank#}6{#/blank#} other. Some other styles include kicking the shuttlecock backwards and forwards between two people. Those who advance to a high level of mastery can perform some actions that are {#blank#}7{#/blank#} (fair) wonderful. The challenge of the increasingly difficult levels of shuttlecock kicking has made it a popular and timeless game among Chinese children.

In San Francisco,a large group of sea lions move themselves out of the bay waters and hang out on PIER 39, which is a popular tourist destination. According to dock（码头） officials, this is the most sea lions seen in the region in 15 years.

"Over 1,000 sea lions have been counted this week," PIER 39 harbor master Sheil a Chandor told many different medias. "The increase in sea lions is usually a good sign of their strong population and healthy living environment," said Adam Ratner, Director of Conservation Engagement at the Marine Mammal（海洋哺乳动物） Center in Sausalito, California.

"California sea lions are sentinels（哨兵） of the ocean," Ratner said. Their population to some extent reflects the health of the ocean. Therefore, seeing a large number of California sea lions is clearly a good thing.

For nearly 35 years, the animals have been a star attraction for visitors. That autumn in 1989, PIER 39 had just been repaired, but the ships had not yet been moved back. At that moment, the sea lions' unexpected arrival not only attracted fans but also created enemies. According to a website, some dock residents and workers were scared away by the strong and very unpleasant smell and noise of their new neighbors, while others saw these animals as a bright spot after the destructive Loma Prieta earthquake.

The officials sought help from the Marine Mammal Center to find a way to deal with sea lions. Ratner said that the final decision is to let the sea lions stay and coexist with humans. "The fact proves that this is really a good thing," he said. "This is just a proof of how we can truly work together and think about how we can share our coasts with marine mammals and other wildlife in a way that benefits all the parties involved."
