IPhone owners are vainer（虚荣）and spend more on clothes and grooming（仪容）than those who have BlackBerrys and Android phones, new research claims.BlackBerry owners earn the most and are more likely to have long-term relationships, while people with Android handsets are most creative and the best cooks.

    The study, carried out by TalkTalk Mobile, surveyed 2,000 owners of the three major smartphone brands to determine whether the choice of handset was an extension(延伸) of their personality. The study rated users in various walks of life using a point scoring system including personalities, daily habits and the type of industries they work in.

    Other results from the study found that people with an iPhone are more image conscious and generally consider themselves more attractive than those with other handsets. They are most likely to describe themselves as adventurous, bright and are most likely to work in media, publishing and education. They also believe their boss rates them highly. Apple owners also tend to have done more travelling and are the most active on social media sites.

    BlackBerry owners were found to be the least punctual(准时的), but despite putting in the least hours at work they are the most active phone user—sending more texts and making more calls in the average day than any other phone user. They are more social and have more friends overall. They also earn nearly two and a half thousand pounds a year more than other smartphone owners, with an average salary of $27,406. BlackBerry users classed themselves so loud and mainly work in the health, finance or property sectors. They were also found to drink more tea and coffee each day than any other phone user.

    Android owners were found to watch more TV than others and drink the most alcohol—consuming more in an average week than iPhone and BlackBerry drinkers. They have the most jobs in engineering, the government and public services and environmental services. They have the best manners and are more shy and relaxed than their counterparts.

    Dan Meader, Director of Mobile at TalkTalk, said,“Many of us have our mobile phones on us almost constantly so they do become an extension of us in many ways. It's interesting to see then how the choice in handset may reflect different aspects of personality and the results do show some unusual difference

    Wearing a red nose for a day may seem like a strange way to raise money for charity. However, it seems to work in Britain

Red Nose Day (RND) is well-known in the UK. The aim of the day is to raise money for a charity called Comic Relief which helps people in need in Africa and in the UK.

    Red nose?

    Comic Relief was started in 1985 by the scriptwriter Richard Curtis. It's called Red Nose Day, as on this day many people buy a plastic red nose to wear! The money made from selling red noses goes to the charity.

    When is RND?

    Red Nose Day takes place every two years in the spring and is now so famous that many people consider it to be an unofficial national holiday. For example, many schools have non-uniform days. This year Red Nose Day was on 13^th March 2015.

    Money

    Across Britain, people are encouraged to “Do Something Funny for Money”. The money that is collected helps children to go to school, and educates the adults with HIV and AIDS. Comic Relief also works closely with disabled and elderly people to make sure they have equal rights and a better life.

    So, if you are ever in the UK on Red Nose Day, now you know why you may find normal people wearing red noses and doing silly things! It's all for a good cause! If you want to find out more about the day, have a look at the official Read Nose Day website.

    The best way of learning a language is using it. The best way of learning English is talking in English as much as possible. Sometimes you'll get your words mixed up (混合) and people will not understand you. Sometimes people will say things too quickly and you can't understand them. But if you keep your sense of humor, you can always have a good laugh at the mistakes you make. Don't be unhappy if people seem to be laughing at your mistakes. It's better for people to laugh at your mistakes than to be angry with you, because they don't understand what you are saying. The most important thing for learning English is: "Don't be afraid of making mistakes because everyone makes mistakes."

    After decades of cat-and-mouse between athletes and the word anti-doping agency (WADA), athletes found what they must have believed to be the ultimate (终极的) doping agent: their own blood. To enhance athletic performance with your own blood, you draw your blood and store it in a freezer. Your body compensates by creating more blood. Then, months later, just before a competition, you can re-inject (注射) the old blood for a boost. As the red-blood-cell count goes up, so does an athlete's ability to absorb oxygen. The more oxygen you get with each breath, the more energy your body is able to bum and the better you are able to perform.

    Although the enhancement is small compared to actual drugs, it can be the difference between a gold medal and a silver medal. Best of all, "extra blood" was never something WADA tested for.

    But WADA wasn't going to sit by and be fooled. What it came up with in response might be a solution to stop doping once and for all: an athlete biological passport (ABP). The idea is to record some biological features of an athlete through testing done at regular intervals. The biological passport's partial implementation (实施)—recording blood and steroid levels—began in January 2014.

    When all necessary biological features are finally combined, WADA will no longer need to worry about finding new methods to detect a drug. It will only have to detect (检测) resulting changes in the body. In the case of blood doping, if the athlete's normal red-blood-cell count is, say, 47%, but then is found to be 51% after a competition, cheating may have been involved.

    WADA is confident that the biological passport could even prevent genetic changes—the ultimate, ever-lasting enhancement—which are surely coming next. If an athlete inserts a performance enhancing gene, it will probably leave detectable changes in the body, that would differ from the athlete's feature in the biological passport.

    Some years ago, Michel-Andre found himself staring at the body of a dead whale on a beach in the Canary Islands. It was obvious that the animal had been struck violently by a ship——but why? Only later, after surveying the whales which lived in the area and measuring the increase of sound pollution from ships did it become clear that there was a link.

    The whales had become desensitised to the noise of approaching boats and were being struck by them, often seriously. "We never thought that this could be something that could kill," recalls (回忆) Andre, who is the director of the Laboratory of Applied Bioacoustics at the Technical University of Catalonia, Barcelona.

    Andre has spent 20 years developing an advanced system to better understand why incidents like this happen. His underwater microphones have exposed a world of deafening sound and animal communication never observed with such clarity(清晰) before.

    It was not an easy task. Sound waves don't travel through water in the uniform, predictable way they do through the air. Instead, the temperature, salinity (盐度) and, flow of water have great effects on their path.

    What can be done? One solution is to change shipping routes to courses where ships are statistically less likely to meet animals. It's also possible to slow ships down to 18km/h or less, which is less likely to seriously injure a whale.

    As for dealing with the root cause of the problem, the UN's International Maritime Organisation has already published guidelines on how to quieten ships, but it will be a while before the effects of such changes might be observed.

    "The ocean is not our world," comments Andre. But it is ours to look after. And thanks to his work, we can better understand the effects of subsea sound pollution.

Every day for a week, a strange, happy visitor would drop to play with Vanessa Prior's pet dog Bobby. She thought Bobby had made a new dog friend. It seemed very friendly and got well along with Bobby. They would run after each other, play on the pool cover, gently wrestle or nap side by side.

At first she thought it was a wild dog. But when she posted a photo of the two playing on her Facebook, a pet rescue center called her. The group told her the Atlanta Wolf Project had been trying to catch the wolf for months, but they failed. Prior gave them new hope.

Because of the wolf's friendship with her pet dog, it was likely to come back to her backyard. Researchers hoped Prior could help them. When they put some traps (陷阱) in the back of her yard, Prior got a very complicated feeling. She couldn't describe what it was, but she was closely surrounded by it. The wolf would be in a safe place, but she would do something that harmed Bobby's feelings.

Researchers told Prior that they would take the rare, black wolf to the Yellow River Wildlife Sanctuary where it would live with another wolf. They didn't think it a fulfilling situation for a wild animal like a wolf to be connecting with humans' life. They need to keep a natural awareness to humans and pets and keep to themselves.

Wolf experts added they would look into the genetics (遗传学) of the animal to try to learn why it liked to get close to people and tried to play with their pets. Some experts believe it could have a history with well-meaning humans. Prior had not expected that they should meet such a special and lovely wolf. She and Bobby just hoped the dear friend all the best.
