Hans Christian Andersen is a Danish writer famous for his fairy tales, many of which depict (描述) characters who gain happiness in life after suffering and conflict.

    Andersen's father was a poor shoemaker and his mother worked as a washerwoman. As a child he was highly emotional, suffering all kinds of fears and shame because of his unmanly interests. Encouraged by his parents, he composed his own fairy tales and arranged puppet (木偶) theater shows. At the age of 14, Andersen moved to Copenhagen to start a career as a singer—he had a beautiful voice. He succeeded in becoming associated with Royal Theater, but he had to leave it when his voice began to change. When casually referred to as a poet, he changed his plans and began to write plays, all of which were refused.

    In 1822, Jonas Collin, the director of the Royal Theater, gave Andersen a grant to enter the grammar school at Slagelse. In 1827, Andersen gained admission to Copenhagen University, where he completed his education. In 1828 he wrote a shot story on travel, a fantastic tale in the style of the German Romantic writer, E. T. A. Hofmann. He traveled widely in Europe and remained a passionate traveler all his life.

    As a novelist, Andersen made his breakthrough with The Improvisatore. The story described a poor boy's integration (融合) into society, an Ugly Duckling theme of self-discovery. The book gained international success and remains the most widely read of all his works.

    In his early collections, Andersen returned to the stories that he had heard as a child, but gradually he started to create his own tales. Most of Andersen's works were original. Only 12 of his 156 known fairy stories drew on folktales.

    The ugliness of the hero or heroine in his stories often conceals (隐藏) great beauty，which is revealed (揭示) after misfortune. Some of Andersen's tales reveal a positive belief in the victory of the good, among them, The Snow Queen and The Ugly Duckling, and some end unhappily, like the Little Match Girl. In The Little Mermaid the author expressed a longing for the ordinary life that he had never had. Andersen never married, and he died in his home in Rolighed in 1875.

    With the development of modern science and technology, the functions of cellphones have changed greatly. {#blank#}1{#/blank#}The only difference may be that they fit in your pocket and you pay by the minute to use them. Some of the things a cellphone can do for you will be available this year:

Surf at speed

    Cellphones that let you use the Web have been around for years. So, what's new? Well ,  faster third-generation (3G)  networks that let you surf at anywhere. {#blank#}2{#/blank#}Possible choices are from IJG Electronics VX 8000 and Motorola V1150.Listen as you go.

    {#blank#}3{#/blank#} There is no doubt that it is about to change. Sony Ericsson's new W8001 can hold around 150 songs in its 500 MB memory. And Samsung's SPH-V5400 even comes with a l. 5 GB hard drive. Mobile phones may eventually replace miniMP3 players, especially for teens. Say cheese.

    Camera cellphones are not new either but most of them have limitations: around l- megapixel  (百万像素 ) .  However new technology has made 2-megapixel units more common ,and 3-megapixel units are showing up soon. Some 2-megapixel models, like Sony Ericsson's K7501, offer limited zoom and focus controls.   {#blank#}4{#/blank#}Portable TV.

    You say you like "watching TV"? That's what Samsung MMA700 wants to give you. The new model lets users watch popular TV programmes~ for a fee. Other choices are Nokia's 6620, Sanyo's MM740 and NEC's N940. {#blank#}5{#/blank#}

    The above are just a handful of what you ' ll see in the coming months.  Further down the road, your mobile phone may play a host of other roles, such as mobile credit card, position locator and so on. So what is there that a cellphone can't do?

A. The NEC model lets you watch public TV - no fee.

B. Without a cellphone, you can do nothing in your daily life.

C. Nowadays, new cellphones are much cheaper than old ones.

D. Today's do-it-all mobiles have a lot in common with the computer.

E. This then allows a carrier to send video, music, and games to your phone.

F. Others, like LG's recent A7110, can even capture 30 minutes of full-motion video.

G. The problem with most cellphone MP3 players is that they hold only a handful of songs.

    Bamboo is one of the world's most useful plants. For thousands of years, bamboo has been used in many different ways-from food to medicine to clothing and, in small ways, as a building material.

    However, bamboo is not often used as a building material in the developed world. A professor at the University of Pittsburgh in Pennsylvania is trying to change that. The professor and his students are testing the strength of bamboo.They are testing how much pressure or weight it can take before breaking.

    Kent Harries is a professor at the University of Pittsburgh. Harries says that testing methods for bamboo need to be the same for all. They need to be standardized. Standardizing test methods for bamboo will help to bring the plant into common use. It will also give engineers and builders around the world a dependable standard.

    Harries says that bamboo is strong in nature. The strength of at least three species of bamboo is similar to steel.Besides its strength, bamboo has other features that make it very useful in building. He says it is resilient(有弹力的), meaning it keeps its shape and strength even under pressure.

    Bamboo also grows quickly. Bamboo that is suitable for construction needs much less resources than wood. The harvest cycle of bamboo is about 3 years. Softwoods such as cedar, pine and spruce have a harvest cycle of about 10 years. And hardwoods that come from flowering plants such as oak and walnut need more than 30 years.

    Bamboo is widely used as food for panda bears. It is also used for flooring and window covers. However, for building, bamboo is not used much outside its native growing area. This is mostly because of its round shape. But there are other reasons too. People think -- or have the mentality--that bamboo is a low quality building material.

How to Drop a Pant Size in a Week

    Dropping one pant size in seven days is a difficult task, but with dedication, exercise and the right diet, you can make it happen.

    Increase your water consumption. Thirst is often misinterpreted as hunger, and if you are drinking the right amount of water, you will find it much easier to avoid snacking. Look to drink at around eight or nine glasses of water every day.

    Lower your calorie count. You can use a calorie calculator to determine how much you need to take in to maintain or lose weight. If you take in fewer calories than you burn each day, you will lose weight as a result. As a rule, an average-sized woman needs to take in less than 1, 300 calories per day for extreme weight loss, as you'll naturally burn around 2,000. Exact measurements differ based on age, height, weight and activity level.

    Cut the junk food. Chips, soda and candy seem harmless if taken as snacks, but can seriously affect your weight loss. Limit yourself to one or two snacks per day and switch your usual snack foods for baby carrots, apples and grapes.

    Break up your meals. If you want to lose weight, try eating four or five small meals per day instead of two or three large ones. This makes it easier for your body to process what you are consuming. Divide your required calories by the number of meals you'll be eating to determine how large each meal should be. Space your meals out two or three hours apart—try meals at breakfast, mid-morning, lunch, afternoon and dinner.

Doing intense aerobic (需氧的) exercise. You have to encourage your body to burn calories if you want to drop pounds and inches. Running is by far the fastest calorie burner, with the potential for 986 calories per hour. If you're unable to run, use an elliptical machine (椭圆机), jump rope, or participate in a high-impact aerobics class.

Humans have sailed the oceans' surfaces for millennia（千年）, but their depths remain effectively uncharted. Only about a quarter of the seafloor has been mapped at high resolution. Maps of most regions display only approximate depths and often miss entire underwater mountains or canyons（峡谷）.

So a group of researchers has recruited some deep-diving experts: Elephant Seals and Weddell Seals. Scientists have been placing trackers on these blubbery marine mammals around Antarctica for years, gathering data on ocean temperature and salinity. For a new study, the researchers compared these dives' location and depth data with some of the less detailed seafloor maps. They spotted places where the seals dove deeper than should have been possible according to the maps--meaning the existing depth estimates were inaccurate.

In eastern Antarctica's Vincennes Bay, the diving seals helped the scientists find a large, hidden underwater canyon. An Australian research ship called the RSV Nuyina later measured the canyon's exact depth using sonar, and the researchers have proposed naming their find the Mirounga-Nuyina Canyon—honoring both the ship and the involved Elephant Seals, genus（动植物的属）Mirounga.

But seals can't map the entire ocean floor. The trackers used in the study could pinpoint a seal's geographical location only within about 

1.5miles. Plus, because the seals don't always dive to the bottom of the ocean, they can reveal only where the bottom is deeper than in existing maps—not shallower. McMahon notes that scientists could improve on these data by using more precise GPS trackers and analyzing the seals' diving patterns to determine whether they have reached the seafloor or simply stopped descending.

The current seal-dive data can still be valuable for an important task, says Anna Wåhlin, an oceanographer. The deep ocean around Antarctica is warmer than the frigid waters at the surface, and seafloor canyons can allow that warmer water to flow to the ice along the continent's coast, Wåhlin explains. To predict how Antarctica's ice will melt, scientists will need to know where those canyons are and how deep they go.

Heads or Tails?

Careful: It's not 50-50

The phrase "coin toss" is a classic synonym for randomness. But since the 18th century, mathematicians have 1 that even fair coins tend to land on one side slightly more often than the other. Proving this tiny bias, 2 , would require hundreds of thousands of carefully recorded coin flips, making laboratory tests a logistical （后勤的，组织协调的） 3 .,

František Bartoš, currently a Ph.D. candidate studying the research methods of psychology at the University of Amsterdam, became interested in this 4 four years ago. He couldn't 5 enough volunteers to investigate it at first. But after he began his Ph.D. studies, he tried again, recruiting 47 volunteers from six countries. Multiple weekends of coin flipping later, including one 12-hour marathon 6 , the team performed 350,757 tosses, breaking the previous record of 40,000.

With one side initially upward, the flipped coin landed with the same side facing 7 as before the toss 50.8 percent of the time. The large number of throws allows 8 to conclude that the nearly 1 percent bias isn't a fluke （侥幸）. "We can be quite sure there is a bias in coin flips after this data set," Bartoš says.

The leading theory explaining the 9 advantage comes from a 2007 physics study by Stanford University statisticians, whose calculations predicted a same-side bias of 51 percent. From the moment a coin is launched into the air, its entire track — including whether it lands on heads or tails — can be calculated by the laws of 10 . The researchers determined that airborne coins don't turn around their symmetrical axis （对称轴）; 11 , they tend to move off-center, which causes them to spend a little more time high in the air with their initial "up" side on top.

For day-to-day decisions, coin tosses are as good as random because a 1 percent bias isn't 12 with just a few coin flips, says statistician Ameli, who wasn't involved in the new research. Still, the study's conclusions should eliminate any lasting doubt regarding the coin flip's slight bias. "This is great experiment-based evidence 13 the bias," she says.

It isn't difficult to prevent this bias from influencing your coin-toss matches; simply 14 the coin's starting position before flipping it should do the trick. But if your friends are 15 the tiny bias, you may as well benefit from your slight advantage. After all, 51 percent odds beat a casino's house advantage. "If you asked me to bet on a coin," Bartoš says, "why wouldn't I give myself a 1 percent bias?"
