When Luke went to university he thought he would be on a new journey in life and getting his own place. In the UK, it's common to fly the nest at a fairly young age. Many choose a flat-share; others make plans to get on the property ladder.

    But the current economic situation forced Luke back to his mum's house at the age of 27. And he's not alone: a quarter of young adults in the UK now live with their parents. The Office for National Statistics said more than 3.3 million adults between the ages of 20 and 34 were living with their parents in 2013.

    Lack of jobs and the high cost of renting accommodation made Luke change his plans. He's upset. "There's something very difficult about being an adult living in an environment where you're still a child," he says. "It limits me socially; sometimes I feel it limits me professionally."

    Indeed, many young people have no choice but to stay at "the hotel of Mum and Dad".

    Krissy had to return home after a year away and now lives in rather terrible conditions, sharing the family's three-bedroom house with her sisters. She says they end up getting on each other's nerves when it's time to use the bathroom in the morning.

    Of course, living with your parents is not unusual in some countries. Economic conditions, culture, or family traditions mean many young people stay at home until they get married. Even then, it can be too expensive to rent or buy a house and the married couples continue to live at one of their parents' homes.

    But some parents seem to enjoy having their kids back at home. Janice's daughters are part of what's being called "the boomerang generation". She says, "I get to share their lives with them, and I've got to know them all as adults. We have the sort of conversations that good friends do."

    So for some it's a win-win situation — spending time with your families, and saving money.

    Maddie Messe, 13, has always loved Temple Run, a mobile game that sends her racing through swamps (沼泽) and forests to outrun a pack of crazed monkeys. What she didn't love was being forced to play as a boy — unless she was willing to buy a female version. “I felt like l was being cheated or misrepresented,” Maddie explains．“Girls are just as capable (有能力的) of running away from monkeys as boys are.”

    So last winter, Maddie researched 50 of the most popular iPhone games. What she found was infuriating：90 percent offered free male characters, but only 15 percent let you play as a female for free.

    Armed with those statistics, Maddie drafted a spirited article and fired it off to several major newspapers. The Washington Post agreed to run the piece, which attracted millions of readers around the globe — including the makers of Temple Run! “We realized she had a point,” says Natalia Luckyanova, the game's co-creator. “It was the kick in the pants we needed to say, ' We should fix it．' So we did.”

    Now you can play Temple Run with a female character for free, but Maddie hopes her campaign inspires something deeper.“If you don't see characters that look like you on TV or in movies or games, speak up! Just do your research first,”says Maddie. “One well-supported argument is much more effective than a million angry complaints.”

    Back in the 1860s, a British scientist named Henry Walter Bates noticed something interesting in the animal world: a kind of butterfly, Common Mormon, can change the pattern on its wings so that it looks like another butterfly species, the Common Rose, which is poisonous for birds to eat.

    Bates argued that animals develop this ability to protect themselves from being eaten. This theory had been widely accepted by scientists. But one question remains: how do these animals manage to do that?

    After more than 150 years, scientists are finally able to answer that question-it is all down to a gene(基因) called “doublesex", according to a study published on March 6 in the journal Nature.

    In fact, scientists have long known that genes are responsible for this useful ability. But until the new study, scientists hadn't been able to find out which genes in particular were responsible.

    Scientists at the University of Chicago compared the genetic structures of the Common Mormons that changed their wing patterns with those of ones that did not. And all the results pointed to a single gene, “doublesex”.

    This was much to the scientists' surprise. They used to expect that something as complex as this would be controlled by many different genes. For example, one gene would control the color of the upper part of the wing, one would do so for the lower part.

    However, the “doublesex” gene doesn't quite do everything by itself. Instead, it acts like a switch-it “tells” other genes to change the wing patterns. Isn't that clever?

    Scientists believe that this special ability of the “doublesex” gene on Common Mormon was developed throughout the long history of evolution. “The harmless species gains an advantage by resembling something predators(捕食者) avoid,” Sean Carroll, a scientist told Nature. “it was obvious evidence for natural selection.”

    Edgar Allan Poe was an American writer who helped shape the course of American literature. His life was full of tragedy and despair, but he managed some of the most influential American literature of the 19th century and continues to influence writers to this day.

    The early life of Edgar Allan Poe was quite miserable.Born in 1809, Poe was not yet three years old when his parents died.Adopted by a wealthy family,he got into trouble at school.He  entered the United States Military Academy at West Point,but he dropped out without graduating. His misery continued to his adult life.Later,because of a failed marriage, he suffered from mental illness. He was so upset about real life that he turned to writing.Expressing himself in an unreal and imaginary world was his only comfort.

    The tragedies in Poe's life influenced the tone,style and contents of his writing.His stories usually include death,which help build his reputation as a master of"dark"literature.In his The

    Tell-Tale Heart, the main character goes crazy and kills his roommate while in The Black Cat, the narrator kills his cat in a fit of madness.

    Poe died at the age of 40 in 1849.His life was tragic and short,but his legacy(遗产) is enormous.Poe is credited with creating crime fiction,and many say he contributed greatly to the appearance of science fiction.Fascinated by the scientific theories and new inventions of his time, he wrote about imaginary societies in the future.Writers such as Arthur Conan Doyle,the author of Sherlock Holmes,regarded Poe as the father of detective fiction. Jules Verne, a French writer who helped popularize science fiction,said Poe's work had a direct influence on the stories he wrote.

    On March 2, at the meeting held ahead of the yearly session of the CPPCC National Committee(全国政协大会), interpreter(口译员)Yao Mengyao caught the attention of many with her "quick reaction and correct translation," Xinhua noted,

    Yao began her studies in English in primary school where she would listen to English tapes. She ofen spoke to her teacher about English-related topics that were not limited to the ones in her textbooks, "They were always very professional uncommon topics, "said Yao's senior school teacher Shen Yingzi,

    Like Yao, Zhang Lu is a regular interpreter for China's top leaders, including Premier Li Keqing and former Premier Wen Jiabao Her effortless but on-point translations of ancient poems mentioned by former Premier Wen won praise.

    So how do interpreters reach their top positions?

    The reason for their success is largely hard work. Other than when they go out on visits with Chinese leaders, the interpreters follow a very strict schedule. Zhang called this schedule"an unshakable plan". They listen to foreign media such as BBC, VOA or CNN through TV or radio for their training.

    It is reported that a month before the two sessions(两会), the interpreters get notice of the spokesperson they are going to interpret for. They then make full use of this month to prepare themselves. They try to predict the questions that might be asked and consider the sayings the spokesperson might use when they answer the questions.

    In truth, there is no secret to their success: It's all a matter of skill and hard work.
