Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer, saying studies showed a clear link. “Our suggestion is for people to increase their intake, through diet or a vitamin supplement. ” Dr.Cedric Garland said in a telephone interview.

    Garland's research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004.

    “There's nothing that has this ability to prevent cancer,” he said, urging governments and public health officials to do more to fortify foods with vitamin D. Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units(IU) a serving. People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day, Garland said, adding that it was well within the safety guidelines established by the National Academy of Sciences.

    The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine.

    African Americans, who don't produce as much of the vitamin because of their skin colour, could also benefit significantly from a higher intake, the authors said.

    It happened to me recently. I was telling someone how much I had enjoyed reading Barack Obama's Dreams From My Father and how it had changed my views of our President. A friend I was talking to agreed with me that it was, in his words ,“a brilliantly written book” However, he then went on to talk about Mr. Obama in a way which suggested he had no idea of his background at all. I sensed that I was talking to a book liar.

    And it seems that my friend is not the only one. Approximately two thirds of people have lied about reading a book which they haven't. In the World Book Day's “Report on Guilty Secrets”, Dreams From My Father is at number 9. The report lists ten books, and various authors, which people have lied about reading, and as I'm not one to lie too often (I'd hate to be caught out), I will admit here and now that I haven't read the entire top ten. But I'm pleased to say that, unlike 42 percent of people, I have read the book at number one ,Gorge Orwell's 1984. I think it's really brilliant.

    The World Book Day report also has some other interesting information in it. It says that many people lie about having read Jane Austin Austen, Charles Dickens, Fyodor Dostoevsky (I haven't read him, but haven't lied about it either) and Herman Melville.

    Asked why they lied, the most common reason was to “impress” someone they are speaking to. This could be tricky if the conversation became more in-depth!

    But when asked which authors they actually enjoy, people named J.K. Rowling, John Grisham, Sophie Kinsella (ah, the big sellers, in other words). Forty-two percent of people asked admitted they turned to the back of the book to read the end before finishing this story (I will come clean: I do this and am astonished that 58 percent said they had never done so.).

    Homestay provides English language students with the opportunity to speak English outside the classroom and the experience of being part of a British home.

    What to Expect

    The host will provide accommodation and meals. Rooms will be cleaned and bedcovers changed at least once a week. You will be given the house key and the host is there to offer help and advice as well as to take an interest in your physical and mental health.

    Meal Plans Available

    Continental Breakfast

    Breakfast and Dinner

    Breakfast, Packed Lunch and Dinner

    It's important to note that few English families still provide a traditional cooked breakfast. Your accommodation includes Continental Breakfast which normally consists of fruit juice, cereal(谷物类食品), bread and tea or coffee. Cheese, fruit and cold meat are not normally part of a Continental Breakfast in England. Dinner usually consists of meat or fish with vegetables followed by dessert, fruit and coffee.

    Friends

    If you wish to invite a friend over to visit, you must first ask your host's permission. You have no right to entertain friends in a family home as some families feel it is an invasion of their privacy.

    Self-catering Accommodation in Private Homes

    Accommodation on a room-only basis includes a shared kitchen and bathroom facilities and often a main living room. This kind of accommodation offers an independent lifestyle and is more suitable for the long-stay student. However, it does not provide the same family atmosphere as an ordinary homestay and may not benefit those who need to practise English at home quite as much.

    UK is becoming a popular destination for people who wish to study abroad. However, Britain is quite an expensive place to study and live in. Tuition fees have now reached £ 9,250 a year and students also face some of the highest living costs in the world.

    Fortunately, there are a number of countries where universities offer degree programs entirely in English, along with the chance to learn the local language while you live there. Here are three of the options.

    Tianjin University

    Moving to China is not for the faint hearted. Undergraduate degree courses at Tianjin last four years. Living costs are only around £ 400 a month and tuition fees are £ 2,300 a year. Flights will cost £ 3,600 over the four years. The total cost, at £ 28,800, is still around half that of a three-year degree in Britain. Tianjin is one of the world's latest cities and is only a half-hour train ride from Beijing. Three undergraduate programs are offered in English: Chemical Engineering, Environment & Energy and Pharmaceutical Science.

    University of Amsterdam

    The Dutch capital is not a cheap city to live in, but standard tuition fees of £ 1,800 a year make it significantly cheaper than a British degree. There are 14 bachelor's degrees on offer that are taught in English, including Political Science, Economics & Business Economics and Actuarial Science. Nearly all Dutch people speak English, making it an easy country to get by in.

    University of Milan

The University of Milan's fees range from £ 140 to £3,650 a year. The one bachelor's degree offered entirely in English—Political Science is a three-year course. While living costs in Milan are high, the significantly lower fees make it a cheaper option than a British university.

    This year's flu season is pretty scary. To try to minimize the effects, public officials are still urging anyone who hasn't yet gotten their flu shot to get one as soon as possible. However, even if every single person got a shot in the arm, the vaccine(疫苗)—with its excellent 36 percent effectiveness—would not prevent everyone from getting infected with the annoying virus. Knowledge is power, so here's what goes on in your body when you come down with the flu.

    The influenza virus primarily attacks your nose, throat, and the tubes that lead to your lungs. But the flu is so much more than that. Your muscles ache, your head hurts, and your appetite goes down, among other things. To our surprise, almost all of these symptoms have less to do with the virus itself than with your immune(免疫的)response to them. Unfortunately, the very defense you have in place to get rid of the flu is the reason you feel so painful when you recover.

    The virus usually enters through your mouth, typically by way of your hands But it takes a few days for symptoms to set in. While this process might cause some harm to your nose and throat, it's nothing major, and nothing like the symptoms that typically accompany a bad or even mild case of the flu.

    The real fun starts when your immune system begins to fight. Your immune system comes in two parts: the innate system and the adaptive. The innate immune system is essentially an all-purpose tool. As soon as your body senses the presence of any injury or invader (入侵者), the innate immune system launches into action by producing tiny proteins called cytokines and chemokines. The cytokines reproduce almost immediately and start to attack the virus. This increase in immune cells creates an serious inflammation(炎症) throughout the body. But the worst is still to come. Meanwhile, the chemokines work with the adaptive immune system to help create T cells. These cells are a special type of white blood cell that works in a much more specific way: They find the influenza virus, identify what's special about it, and create something unique on their surface that finds and destroys similar invaders.

    I am a strong believer that if a child is raised with approval, he learns to love himself and will be successful in his own way.

    Several weeks ago, I was doing homework with my son in the third grade and he kept standing up from his chair. I kept asking him to sit down, telling him that he would concentrate better. He sat but seconds later, as if he didn't even notice he was doing it, he got up again. I was getting annoyed, but then it hit me: I started noticing his answers were much quicker and right when he stood up. Could he be focused while standing up?

    This made me start questioning myself and what I had been raised to believe. I was raised to believe that a quiet child was more likely to succeed. This child would have the discipline to study hard, get good grades and become someone important in life. Kids that were active and loud would only be objects of stares.

    Now people perhaps come to realize that their kids are born with their own sets of DNA and personality features, and all they can do is loving and accepting them. As parents, throughout their growing years and beyond that, we need to be our kids' best cheerleaders, guiding them and helping them find their way.

    I have stopped asking my son to sit down and concentrate. Obviously, he is concentrating, just in his own way and not mine. We need to accept our kids and their ways of doing things. This way may have worked for me but doesn't mean we need to carry it through generations. There is nothing sweeter than seeing our children being individuals. It makes us happy and that's just the way I want my kids to live life.
