Evaluating Sources (来源) of health Information

    Making good choices about your own health requires reasonable evaluation. A key first step in bettering your evaluation ability is to look carefully at your sources of healthy information. Reasonable evaluation includes knowing where and how to fins relevant information, how to separate fact from opinions, how to recognize poor reasoning, and how to analyze information and the reliability of sources. {#blank#}1{#/blank#}

    Go to the original source. Media reports often simplify the results of medical research. Find out for yourself what a study really reported, and determine whether it was based on good science. Think about the type of study. {#blank#}2{#/blank#}

    Watch for misleading language. Some studies will find that a behaviour “contributes to” or is“ associated with” an outcome; this does not mean that a certain course must lead to a certain result. {#blank#}3{#/blank#} Carefully read or listen to information in order to fully understand it.

    Use your common sense. If a report seems too good to be true, probably it is. Be especially careful of information contained in advertisements. {#blank#}4{#/blank#} Evaluate “scientific” statements carefully, and be aware of quackery(江湖骗术).

    {#blank#}5{#/blank#} Friends and family members can be a great source of ideas and inspiration, but each of us needs to find a healthy lifestyle that works for us.

    Developing the ability to evaluate reasonably and independently about the health problems will serve you well throughout your life.

A. Make choices that are right for you.

B. The goal of an ad is to sell you something.

C. Be sure to work through the critical questions.

D. And examine the findings of the original research.

E. Distinguish between research reports and public health advice.

F. Be aware that information may also be incorrectly explained by an author's point of view.

G. The following suggestions can help you sort through the health information you receive from common sources.

    In many big cities, a lot of old people keep birds, cats, dogs and other animals in their houses. These animals are friendly to the old people and never leave them. So the old people love them and see them as their good friends or families.

    It's not difficult to keep these lovely animals at home. But you have to take them to animal hospitals to give them needles (注射), so they won't get ill or they will make people ill. Now there are lots of animal food stores here and there. People can buy good animal food for their animals there. Old people can buy animal food on the phone or on the Internet. But it's a little more expensive.

    Sometimes it's kind of dirty and dangerous to keep animals. They sometimes look dirty and smell terrible and can be dangerous. For example, an old woman in Shanghai lost her life on the street for her pet dog.

    Maybe old people in big cities have many reasons to keep these nice and clever animals. They may feel lonely when their children leave. And these pets can be their great helpers. They are their good friends and help them in many things.

    They are called "sea parrots", and sometimes "clowns (小丑) of the sea"!

    Atlantic puffins (海鹦) are small seabirds which are around 25 cm in length. They have black and white feathers and a large parrot-like beak (鸟喙). The beak changes color during the year. In winter, the beak has a dull gray color, but it turns orange in spring!

    Puffins spend most of their lives out at sea, resting on the waves when not swimming. They live on the eastern coast of Canada and the United States, and the western coast of Europe.

    Puffins live off small fish such as herring, hake and sand eels. Puffins flap (拍) their wings up to 400 times a minute and speeding through the air at up to 88 km an hour. Wow! What's more, puffins can dive down 60m under water in search of their favorite fish.

    In spring and summer, thousands of puffins stay together on the coasts and islands of the North Atlantic Ocean to start a puffin family. They usually pair up with the same partner as before some may have been together for 20 years! Puffins dig out a hole usually in a grassy bank. Both parents take it in turn to incubate (孵化) the egg for the next 36-45 days!

Although puffins are not classed as an endangered animal, their population in some places is becoming smaller. The main reasons are overfishing, which can lead to a shortage of food for puffins, and pollution—especially oil spills (溢出). Not only does the oil make these beautiful birds sick, it harms their feathers.

    It is a psychological strategy that all parents will be familiar with: instead of scolding an misbehaving child, focus instead in rewarding them for good behaviour.

    Now the idea is well received outside the nursery, with implications for everything from recycling clothes to policing.

    Consumers end up with piles of unwanted clothes. Every year in the UK, 300,000 tonnes ends up in landfill — 235 million individual items.

    Now however, apps such as ReGain, Regive and Stuffstr are making it simpler — and more worthwhile — for people to return their unwanted clobber.

    The ReGain app can be used to find one of 20,000 drop-off points. In return, the diligent consumer earns rewards such as discount coupons for high street retailers. Stuffstr works in partnership with John Lewis to help people get cash in return for unwanted items from the chain.

    “Possibly the one prediction that we economists get right is that if you incentivise (激励) a behaviour, you will get more of it,” says Dr Matthew Levy, a lecturer in economics at the London School of Economics.

    He cites research, including his own, showing that financial incentives encouraging regular exercise, stopping smoking and losing weight effectively promote healthy behaviours and that there is no backlash when the incentives are removed.“If anything, the incentives can be used to jump-start a healthy habit that keeps going,”he says.

    In the four months after its launch, the ReGain scheme received almost 17,000 parcels containing 47 tonnes of used clothes and shoes, of which 95% could potentially be reused, according to its founder Jack Ostrowski.

    “We need to find a way to influence behaviour, and discount coupons help,” he says. The platform is also working with brands and retailers to find ways to divert used clothes from landfills and into the production of new clothes, he adds.

    Other reward schemes have had success in encouraging behavioural change.

    When police in Canada issued “positive tickets”— coupons for free food or movie tickets — to reward good behaviour among young people, they reported an almost 50% drop in youth-related service calls.

    “My officers would say' In the old days we'd drive up in the police car and the kids would run away from us, now they run to us'.”

    In a similar venture, Hull city council have announced plans to launch a digital reward token — the HullCoin — that can be earned by volunteering and spent at local retailers.

    Elsewhere, a study on the recruitment of health workers in Zambia found that highlighting economic incentives during the recruitment process caused future employees to be more motivated and task-focused.

    “Obviously different groups are motivated by different factors,” says Ostrowski. “For some, the feel good factor is enough, and for others, that reward stimulus is required.”

    While the start of a new school year is always exciting, this year was even more so for some elementary school students in Auckland, New Zealand. They became the world's first kids to be “taught” by a digital teacher, Will. Will is just an avatar(用户头像) that appears on the student's desktop, tablet, or smartphone screen, not a human-like robot walking around the classroom.

    Auckland energy company Vector and AI company Soul Machines worked together to develop Will, which has been modeled after the human brain and nervous system, allowing it to perform human-like behavior. The digital teacher is currently assigned to teach Vector's “Be sustainable with energy,” a free program for Auckland elementary schools.

    Just like the humans it replaced, Will is able to instantly react to the students' responses to the topic. Thanks to a webcam(网络摄像头) and microphone, the avatar not only responds to questions the kids may have, but also picks up non-verbal cues(非口头提示). For instance, if a student smiles at Will, he responds by smiling back. This two-way interaction not only helps capture the students' attention, but also allows the program's developers to monitor their engagement, and make changes if needed.

    Vector's Chief Digital Officer, Nikhil Ravishankar says, “What was fascinating to me was the reaction of the children to Will. The way they look at the world is so creative and different, and Will really captured their attention.”

    Will, in place since August 2018, has been a great success thus far. However, regardless of how popular it becomes, Will is unlikely to replace human educators any time soon. For one, the avatar's knowledge base is severely restricted. But more importantly, even the smartest digital avatars could never predict and react to all the unexpected situations that educators have to deal with on a daily basis. However, it could come in handy as a “personal tutor”, providing kids with one-on-one help on specific subjects or even topics.

Finding time for yourself

    Few people, these days would disagree with the theory that it's vital to take time for yourself. Creating some space for enjoyment and restoration each day or at least every week, is a win-win proposition. It'll make you both happier and more effective in fulfilling your responsibilities at work and home. {#blank#}1{#/blank#}. Here are some useful suggestions.

    Don't wait until it feels right. {#blank#}2{#/blank#}, so you want to tell yourself that you'll only relax once everything is under control. But since both work and family life generate an infinite number of to-dos, that strategy is doomed (注定要失败的). As time-management writer Laura Vanderkam points out, it's far more useful to learn to tolerate the discomfort of knowing your email inbox is filling up, or that the living room is still a pigsty.

    {#blank#}3{#/blank#}. It's all too easy to fill 'me time' with things you think you should enjoy, above all exercise. If you genuinely love such activities, they're perfect. But if the truth is that you don't, you'll only get angry. {#blank#}4{#/blank#}, even when the person doing the telling is ourselves. Make sure at least a small part of your week is spent doing something you can honestly say you enjoy for itself.

    Pay attention to good feelings. Once you do get some restorative time, borrow a Buddhist technique for making it count: when you realize you're enjoying yourself, spend half a minute consciously paying attention to the feelings of pleasure. {#blank#}5{#/blank#}.

A. Choose true enjoyment

B. We hate being told what to do

C. Make commitments in advance

D. It's unpleasant to have unfinished tasks bother you

E. So, you'll often find that those feelings increase as a result

F. Making a plan in advance can create the space you need for your own happiness

G. Making sure you actually get a moment to yourself requires a shift in perspective
