Robots writing newspapers

    Whether it's robots working as hotel receptionists or artificial intelligence creating poetry, it's becoming more and more common to read about technology doing the jobs of humans.

    And now, it seems that software is even capable of writing news stories –such as the very one you're reading.

    Recently the Press Association (PA), a UK news service, has created a computer program that's capable of creating articles that are almost impossible to tell apart from those written by human journalists.

    Called “robo-journalism”, such software “teaches” itself by analyzing thousands of news stories written by humans. The PA's software is already so advanced that many UK newspapers and websites publish articles created by it.

    According to the Reuters Institute of Journalism, many publishers are using robo-journalism to release interesting information quickly, from election results to official figures on social issues. For example, The Washington Post has its own robo-journalism software, Heliograf. Heliograf “wrote “over 850 articles in 2017, as well as hundreds of social media posts.

    So what does this mean for regular journalists?

    “We're naturally wary about any technology that could replace human beings,” Fredrick Kunkle, a Washington Post reporter, told Wired.

    “But this technology seems to have taken over only some of the work that nobody else wants to do.” “Indeed, it appears that robo-journalism software is designed to help humans, rather than take away their jobs.

    “In the future, Heliograf could do things like search the web to see what people are talking about, check The Washington Post to see if that story is being covered, and, if not, alert(提醒) editors or just write the piece itself.”Wired reporter Joe Keoha wrote.

    However, Joshua Benton at Harvard University's Nieman Journalism Lab believes that while robo-jounalism is undoubtedly going to become more present in newsrooms, nothing can replace traditional human creativity.

“Good journalism is not just a matter of inputs and outputs, it is a craft(技艺) that has developed over decades, “ he told BBC News. “The really difficult part of what professional journalists do—carefully weighing information and presenting balanced , contextualized(全景式的) stories —will be very hard for machines to master.

    The key to losing weight is to understand what really motivates you. Have you ever been excited about losing a few pounds?{#blank#}1{#/blank#} And to help you keep your weight under control, you need some coping strategies.

    Ask questions. When you're researching different dieting products and plans or even talking to a doctor about diets, ask as many questions as you can.{#blank#}2{#/blank#}Ask questions like: Do I have to purchase special meals or supplements? Does the program include a part to help me maintain my weight loss?

    Get real.{#blank#}3{#/blank#} Don't burden yourself with unrealistic expectations. Remember, large amounts of weight loss are not realistic and are most likely not safe or healthy. Talk with your health care professional to determine a healthy weight goal.

    {#blank#}4{#/blank#}To maintain your weight, you must balance your intake of calories with the energy you burn. Just 30 minutes of fast walking in most days can take about 10 pounds off your weight each year.

    Weigh yourself weekly. It's important to track your weight on any diet or weight loss plan, but don't get on the scale every day. Weighing daily won't show you the big picture.{#blank#}5{#/blank#}

A. Stay balanced.

B. Once a week is fine.

C. Stick with your healthy eating plan.

D. Losing one to two pounds a week is a realistic goal.

E. Being well informed will help you choose the best diet for you.

F. Regular weight check-ins will show you your progress over time.

G. If so, you must find a way to turn that excitement into determination.

    Among the most popular forms of dieting is the South Beach diet, developed by Arthur Agatston of Miami, Florida. Dr. Agatston developed the South Beach diet for his patients with heart problems to lose weight. Since weight matters a lot in keeping heart healthy and traditional low-fat diets were too difficult for them to stick to, Dr. Agatston decided to create a plan that could help his patients. At first, the diet was just for his patients. Soon, thanks to his patients' success, the diet became the buzz in Miami, and eventually, word spread across the nation.

    This diet focuses on a healthy balance between carbohydrates（碳水化合物）and fats. It is based on eating a combination of “good” carbohydrates and fats, while limiting those “bad” ones. It is divided into three different phases.

    The first phase lasts for two weeks and is the strictest of the three. During this phase, you are asked to restrict（限制）all carbohydrates (good and bad). You are allowed to eat all types of fish, cheeses, eggs, and nuts, and a large number of vegetables. Most dieters can expect to lose between 8 and 12 pounds during this phase.

    During Phase 2, you are allowed to reintroduce some of those carbohydrates that are not allowed before. You are encouraged to start eating carbohydrates that have a low glycemic index（升糖指数）. But you should keep in mind that the key is moderation（适度）. Most people continue to lose 1-2 pounds per week. You continue with this phase until you reach your target weight.

    Phase 3 is designed to help you keep your weight. During Phase 3, you can reintroduce some of the carbohydrates that have a higher glycemic index, although again, this should be in moderation. Phase 3 is meant to be a way of life.

    Crossing your legs is an extremely common habit. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.

    A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason this happens is because the blood in your legs has to work against gravity to be pumped back to your heart, crossing one leg over the other increases resistance, making it even harder for the blood to circulate. You won't feel any immediate effects, but sitting for long periods of time will hurt you forever.

    Crossing your legs can also lead to neck and back pain. Ideally, it's best for our bodies to sit with our feet planted flat, hip width apart, on the floor, but it's not easy to maintain perfect posture all day at the office. When you sit with your legs crossed your hips are in a twisted position, which can cause one of your pelvic bones(骨盆) to rotate. Since your pelvic bone supports your neck and spine（脊椎）, this can cause pressure on your lower and middle back and neck.

    You also might notice that when you sit with your legs crossed for long periods of time your feet and legs get painful or have the feeling of being asleep. This is because when one leg sits on top of the other it causes pressure on the veins（静脉） and nerves in your legs and feet. It can cause numbness and/or temporary paralysis in the legs, ankles, or feet. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.

    So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.

    Kids and Food: Advice for Parents

    It is important for parents to know how to help their kids eat healthy. Here are a few easy ways:

    Parents control the supply lines. {#blank#}1{#/blank#} Though kids may keep asking for less nutritious foods, parents should decide which foods are regularly provided in the house. Kids won't go hungry. They'll eat what's available in the fridge at home.

    Say goodbye to “clean-plate club”. {#blank#}2{#/blank#} Lots of parents grew up under the clean-plate rule, but that way doesn't help kids listen to their own bodies when they are full. When kids feel full, they're likely to overeat.

    {#blank#}3{#/blank#} Food preferences(喜好) are developed early in life, so try to offer different kinds of food. Likes and dislikes begin forming even when kids are babies. Parents may need to serve a new food on several different occasions(时机) for a child to accept it.

    Food is not love. Find better ways to say “I love you.” When foods are used to reward kids and show love, they may start to turn to food when feeling worried or unhappy. {#blank#}4{#/blank#}

    Kids do as you do. {#blank#}5{#/blank#} When trying to teach good eating habits, try to set the best example.

    Choose nutritious food, eat at the table, and don't forget breakfast.

A. Start them young.

B. Rewrite the kids' menu.

C. Be a role model and eat healthy yourself.

D. Offer praise and attention instead of food treats.

E. Let kids stop eating when they feel they've had enough.

F. You decide which foods to buy and when to serve them.

G. Let kids choose what to eat and how much of it they want.

    A T-shirt that constantly monitors the heart's activity and detects abnormalities could help protect people against stroke. The T-shirt, which can be washed up to 35 times before it needs replacing, has been developed to improve the detection of dangerous heart conditions like atrial fibrillation( 心房颤动), which causes an irregular heart rhythm and raises the risk of stroke.

    At least one million people in Britain are known to have this condition; however, it's estimated that at least another 500,000 have it but haven't yet been diagnosed because they have no obvious symptoms. Some will have symptoms such as chest pain, dizziness and fatigue; but a large number of people have no idea they're ill until they suffer a stroke.

    Detecting atrial fibrillation involves carrying out an ECG(心电图). Conventional ECGs are done in a hospital and involve highly trained teams of staff attaching up to 24 separate electrodes(电极) to different parts of the body to measure electrical signals. But most patients experience abnormal rhythms only intermittently(间歇地). This means the chance of picking them up during a short hospital check is slim.

    Doctors sometimes issue patients with a device called a Holter monitor to wear under their clothes to try to pick up cardiac( 心脏的) problems. This is an electronic box which clips onto your waistband and is connected to a series of electrodes worn on the upper part of your body. But the box itself is quite bulky, hard to hide beneath clothing and involves a dozen or more wires being attached to the patient's chest.

    The Cardioskin T-shirt, which is made from cotton, could be a much more convenient alternative and can be worn 24 hours a day — meaning it is more likely to pick up any abnormal rhythms in the patient's heart. It has 15 tiny electrodes woven into the material which are strategically placed around the chest area to track the electrical signals from the heart as they travel across the main part of your body.

    The electrodes are powered by a battery which can be removed easily when you need to wash the T- shirt and feed results to a microchip which then sends them out wirelessly to an app. This converts( 转换) the data into an easy-to-read chart showing if the heart rate is abnormal. The results are shared with the patient's doctor so they can check the patient's heart without having to call them into the hospital.

    Martin Cowie, a professor of cardiology at Imperial College London, said, “Cardioskin could be an important development for cardiologists.”
