    The Crowne Plaza Hotel in Copenhagen is offering a free meal to any guest who is able to produce electricity for the hotel on an exercise bike linked to a generator (发电机). The idea is to get people fit and reduce their carbon footprint. Guests will have to produce at least 10 watt hours of electricity — roughly 15 minutes of cycling for someone of average fitness. Guests staying at Plaza Hotel will be given meal tickets worth $ 36 once they have produced 10 watt hours of electricity. The bicycles will have smart phones attached to the handlebars measuring how much power is being generated for the hotel.

    The plan, a world-first, will start on 19 April and run for a year. Only guests staying at the hotel will be able to take part. Frederikke Toemmergaard,hotel spokeswoman, said, “Many of our visitors are business people who enjoy going to the gym. There might be people who will cycle just to get a free meal, but generally I don't think people will take advantage of our programme.”

    Copenhagen has a long-standing cycling tradition and 36 % of locals cycle to work each day, one of the highest percentages in the world, according to the website visitcopenhagen. dk. US environmental website treehugger. com recently voted Copenhagen the world's best city for cyclists. “Because Copenhagen is strongly connected with cycling, we felt the bicycle would work well as a symbol of the hotel's green profile (形象).”

How to Do Man-on-the-Street Interviews

    The man-on-the-street interview is an interview in which a reporter hits the streets with a cameraman to interview people on the sport. {#blank#}1{#/blank#} But with these tips, your first man-on-the-street interview experience can be easy.

    ● When your boss or professor sends you out to do man-on-the-street interviews for a story, think about the topic and develop a list of about ten general questions relating to it. For example, if your topic is about environmental problems in America, you might ask, “Why do you think environmental protection is important in America?” {#blank#}2{#/blank#}

    ● Hit the streets with confidence. {#blank#}3{#/blank#} Say, “Excuse me, I work for XYZ News, and I was wondering if you could share your opinion about this topic.” This is a quick way to get people to warm up to you.

    Move on to the next person if someone tells you she is not intereste

    Don't get discouraged.

    ● {#blank#}4{#/blank#}Each interview that you get on the street shouldn't be longer than ten minutes. As soon as you get the answer you need, move on to the next person.

    Grown-ups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins "Twinkle, twinkle, little star" or remember the story of Cinderella or Goldilocks and the Three Bears.

    One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, additional learning trials increase the length of time we will remember it.

    In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as "Twinkle, twinkle, little star" and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.

    The multiplication tables(乘法口诀表) are an exception to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood. The law of overlearning explains why cramming (突击学习) for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one's future development.

Drug problems

    If you're worried about your own or someone else's drug taking or misuse, it's good to know the facts.

Why take drugs?

    Drug users don't start using drugs with the intention of becoming addicted. But many drugs contain addictive substances(物质) and even people who use them occasionally can become dependent and need to use them regularly.

    Reasons why people start using drugs can include: to escape problems they may be having in other parts of their life, peer pressure and fitting in with another group of people, being curious about the effects of drugs.

    If you start to use drugs on a regular basis, or if you become dependent on them, it can affect your family and friends as well as having a serious impact on your own physical and mental well-being.

    Drug overdoses can be fatal. You can die instantly from misusing substances and drugs that you can buy over the counters.

Signs of drug abuse and misuse

    There is not a common list of symptoms that you can use to tell if you or someone you know is misusing drugs. That's because drug use affects different people in different ways, depending on the type of drugs they're using.

    Although anxiety, tiredness and a change in sleeping habits can be signs of drug use, they can also be caused by changes in your body, stress or other problems.

_____________________

    Drugs are categorised into three classes based on their overall level of harm. Class A drugs are the most dangerous, however, all the drugs in all three classes are harmful and addictive.

    Remember that all drugs are illegal, even Class C drugs like cannabis(大麻烟). If you're caught selling them to other people, or carrying a small amount in your pocket, it's likely that the police will get involved.

    If you're found guilty of any of these offences, you may face a fine or time in custody(拘留), with Class A drugs carrying the most severe sentences.

Worried about a friend?

    If you think that one of your friends or relatives is misusing drugs, you may want to approach them and talk about it. It's not your responsibility to make them stop, but you can tell them about how their behaviour is affecting your relationship.

    If they ask for help with their problem, then it's important to listen and help them find the right information and treatment.

National Drugs Helpline

    If you're worried about drug abuse and addiction you can call the National Drugs Helpline on 0800 776 600 for confidential advice—lines are open seven days a week. Calls are free and they won't show up on your phone bill, but you may be charged if you use a mobile.

    When Ron first started with his organization, he loved his job. He went into work every day filled with purpose and passion (热情). Three years later, however, it was hard to recognize him. Now, Ron detests going to work. He feels that his work is meaningless, he's always stressed, and he calls in sick frequently.

    These are basic symptoms (征兆) of burnout. If you've experienced this yourself, it's important that you should know how to recover from it before you have difficulty in having a sense of satisfaction and then dislike your job.

    You first need to know why you've experienced burnout. First, look at any resentment (愤怒) that you feel towards your work. Often, feelings of resentment point to something important that is missing.

    Here's a good example. Jennifer manages a team around the world, so her workday often starts at 6 a.m. She doesn't mind this because she likes her team and her job. But she feels resentful when her boss forgets that she starts work so early and repeatedly asks her to stay late, which causes her to miss important time with her family.

    In this example, burnout wouldn't happen if Jennifer disliked her job; in fact, she loves what she does. She experiences burnout because she hates missing out on family time in the evenings.

    Take time to think about any negative feelings that you have about your role, and try to get to the root of the problem. Once you've known the cause of your burnout, write down at least one way that you can manage that source of stress. This might include giving some of your duties to others, working from home one day a week, or even changing roles.

    The United States of America is faced with serious traffic problems. Too many cars travel on the freeways to and from the city. This heavy traffic causes delays and lots of pollution from cars that are using their engines but not moving anywhere. Many cars going nowhere is called a "traffic jam".

    While many cities in the United States have traffic problems, some of the worst are in Los Angeles, California, which is a big city with a large downtown area. One of the reasons why there is so much traffic is that few people use public transportation to get around.

    Experts say one possible solution to the traffic problems in Los Angeles would be to make people want to use the public transportation system of buses instead of their own cars. People say the buses should be made easier, faster, less costly and more dependable than driving a car.

    One suggestion is to reduce the cost of taking the bus. Also, Los Angeles could make the buses easier for people to use. The buses could travel to more places in the city. And there could be more special lanes on the freeways that only buses could drive in. These changes would make taking the bus faster and easier than driving a car.

    Other experts have said that the best way to ease traffic problems is to charge people money to drive on the freeways. These charges, or tolls, would be for the most crowded roads. The tolls would be in effect during the times of a day when most people drive to work and home. These times in the morning and late afternoon are called "rush hour". People would try to avoid driving on these roads, which would decrease the amount of traffic. Also, the money collected from these tolls could be used to improve the roads and public transportation system.

    After photographer Monni Must's daughter Miya died, the sad mother adopted her black dog, Billy Bean. As Billy became increasingly weak, the thought of its dying was just more than Must could handle. So she decided to clone the dog. “I feared everyone was going to forget Miya," she said, "and my other daughters thought I had completely lost my mind."

    Billy's cells were shipped to ViaGen Pets, a Texas company that provides the cloning service. With more than $50,000, Must picked up a new puppy. "The dog has a real soul and is everything my daughter was—fun, social and kind," she said. "I feel that I still have that touchable connection and not just a spiritual connection.”

    Cloning animals is hardly new. But the recent news that singer Barbra Streisand had cloned her dog grabbed international headlines. People for the Ethical Treatment of Animals(PETA) president Ingrid Newkirk issued a statement saying she would love to talk her out of cloning, noting that millions of wonderful dogs are getting old in animal shelters every year or dying in terrifying ways when abandoned.

    Normally, a doctor takes a tissue biopsy(组织活检), a piece of skin and muscle about the size of a pencil eraser, from the dog. The next step is to take an egg cell from a donor dog, remove the egg's nucleus, and insert DNA from the pet to be cloned. When an embryo(胚胎)develops, it is transplanted in the body of a mother dog.

    In the basic cloning procedure, scientists take an entire adult cell and put it into an egg that's been relieved of its own DNA. The resulting embryo is a clone. However, in many animals, only one in 100 cloned embryos ever leads to a live birth. Some embryos die in the IVF dish or in the mothers bodies. Of those that are born, a few suffer from abnormalities and quickly die. Besides, pet cloning doesn't mean copying everything of your beloved pets.
