I log onto a computer at the doctor's office to say I have arrived and then wait until a voice calls me into the examination room.

    There, a robotic nurse directs me onto a device and then takes my blood pressure. Some time later, in steps the doctor, who is also a robot. He notes down my symptoms and gives me a prescription (处方). I pay for my visit using a credit card machine and return home without having met another human being.

    When I call my dentist's office and actually get a human being on the line, I am thrilled. And when I see the introduction of yet more self-service checkout stations at the grocery store, I feel like shouting, “When it comes to cashiers, make mine human, please!”

    After all, human cashiers sometimes give you a store coupon (优惠券) for items you are buying. Even more than that, real-life cashiers often take an interest in particularly cute children, which can brighten a young mother's day. A cashier may also show compassion (同情) for an elderly person struggling to get that last penny out of her purse.

    What technological device would do any of this? I don't want to go back to the Stone Age, but I'm also worried about a world run by machines. Sometimes when you're chatting with someone, you discover things you need to know. Maybe a receptionist needs prayers said for a sick child. Maybe a salesperson can offer a bit of encouragement to a customer who is feeling tired.

Machines can be efficient and cost-effective and they often get the job done just fine. But they lack an element so important to everyday life.

    Call it the spirit, the soul or the heart. It is something no machine will ever have. It is being human that prompts us to smile at others, which may be what they need at that moment.

                                   I love Fridays. And so I celebrate Fridays.

    After dropping my son off at school I head to Starbucks to pick up a coffee treat or another. Then instead of driving straight home I take a long route through the most beautiful roads I can find. I see footballs being passed on lawns, hamburgers being thrown on grill（烤架）, and parties everywhere swinging into action.{#blank#}1{#/blank#}

    The o0ther day I came out from the doctor's office happy over a positive prognosis（预断）. Seeing the signs of spring around me-flowers, birds, sunshine, I was suddenly ready to celebrate. {#blank#}2{#/blank#}

    My mind rebelled. “What are you doing? It's Tuesday! Coffee treats are reserved for Fridays!”{#blank#}3{#/blank#} Why should Fridays be any more special than any other day of the week? Why waste six days while waiting to celebrate the seventh? Minutes later I was walking back to my car with a big smile on my face and a coffee in my hand.

    A small victory, to be sure, but it's also an accurate example of how many of us live our lives. We're waiting for conditions to be right before we allow ourselves to enjoy our time here on earth. Maybe when we finally graduate from college and get a job, it will be time to celebrate, or perhaps when our babies are old enough to be in school all day. We'll celebrate when the car is paid off, or enjoy life when we're finally able to retire. {#blank#}4{#/blank#} What if we moved a little of that “Friday feeling” into our rainy-day Mondays, our dull Tuesday and our mid-week Wednesdays? {#blank#}5{#/blank#}

    Angel Garcia Crespo is a computer engineer at Carlos III University of Madrid in Spain. His group has invented a new way for deaf-blind people to "watch" TV. The idea for the technology grew out of previous work by his group. The team had already worked on making audiovisual(视听的) materials accessible to people with either vision or hearing disabilities. But the group wanted to help people with both challenges. So they asked some deaf-blind people what would help.

    In addition to relying on their sense of touch to communicate, deaf-blind people can also get and send information with a Braille line. The Braille system uses patterns of raised dots to stand for letters and numbers. A Braille line is an electronic machine with a changeable Braille display. Dots rise up or drop down based on the information sent to the machine.

    Now the new system changes TV signals to data a Braille line can use. "The key to the system is the possibility of using subtitles(字幕) to collect TV information, " Garcia Crespo explains. "Subtitles travel with the image(影像) and the audio in electromagnetic waves we don't see. But an electronic system can keep those waves. "

    First, a computer program, or app, pulls out the subtitles and visual descriptions from the broadcast signal. The system then combines the information and changes both into data for Braille.

    Now another app gets to work, which sends the data out to people's Braille lines on demand. "This is done in real time, in less than a second," Garcia Crespo says. This lets a deaf-blind person "watch" TV as it's broadcast. The system will work with various Braille lines, as long as there's a bluetooth connection available. Now, the system is only used in Europe, and it should soon be available in the US.

    Scientists have found evidence of a link between social and economic status and childhood attention deficit disorder(ADHD)(注意力缺陷多动障碍)in the UK. A team led by the University of Exeter Medical School analysed data from the Millennium Cohort Study, a database of more than 19, 500 UK children born between 2000 and 2002 .The study was published in the Journal of Child Psychology and Psychiatry.

    Findings showed that more children with ADHD came from families below the poverty line than the UK population as a whole, with average family incomes for households whose study child was affected by ADHD at £324 per week, compared to £391 for those whose child was not. The study found the odds (机会)of parents in social housing having a child with ADHD was roughly three times greater than for those who owned their own homes.

    The team also found that the odds of younger mothers having a child with ADHD were significantly higher than for other mothers. Mothers with no qualifications were more than twice as likely to have a child with ADHD than those with degrees, and lone (孤独的)parents were more likely to have a child with ADHD diagnosis than households with two live-in parents.

    Information was gathered from surveys when the cohort children were nine months old, and at the ages of three, five, seven and eleven.

    Dr Ginny, of the University of Exeter Medical School, who led the study, said, "There is a genetic element to ADHD, but this study provides strong evidence that ADHD is also associated with a disadvantaged social and economic background. Some people believe that ADHD in children causes disadvantage to the economic situation of their family, but we found no evidence to support that theory. It's important to discover more about the causes of this disorder so that we can look towards prevention, and so that we can target treatment and support effectively. "

    Did you once make you friends angry or unhappy because of your words? Are you having trouble getting people to reply to your requests? {#blank#}1{#/blank#} Learn how to say things the right way with this great guide!

    Could you give me five minutes? vs Go away.

    {#blank#}2{#/blank#} When you're busy and can't do anything else, just saying "Go away" is certainly not right. You can keep everyone happy by saying "Could you give me five minutes?"

    Excuse me. vs Move.

    Telling someone to "Move out of the way" is very impolite. The next time someone is in your way, saying "Excuse me" is a good idea. {#blank#}3{#/blank#}

    I'm afraid I can't. vs No.

    {#blank#}4{#/blank#} People will think it impolite to simply say "No". The next time you have to refuse an invitation, you'd better say, "I'm afraid I can't."

    Would you mind...? vs Stop it!

    Someone doing something you don't like, and perhaps being impolite. {#blank#}5{#/blank#} To get the result you want, it's not a good idea to shout "Stop talking on your phone in the cinema!" and it's a good choice to ask them politely with the sentence, "Would you mind not using your phone in the cinema, please?"

Each day, 10-year-old Seth asked his mom for more and more lunch money. Yet he seemed skinnier than ever and came home from school hungry. It turned out that Seth was handing his lunch money to fifth grader, who was threatening to beat him up if he didn't pay.

Most kids have been made fun of by a brother or a friend at some point. And it's not usually harmful when done in a playful and friendly way, and both kids find it funny. But when teasing becomes hurtful, unkind, and constant, it crosses the line into bullying and needs to be stopped.

Bullying is intentional torment(折磨)in physical or psychological ways. It can range from hitting, name-calling and threats to blackmailing(勒索)money and possessions. Some kids bully others by deliberately separating them and spreading rumours about them. Others use social media or electronic messaging to make fun of others or hurt their feelings.

It's important to take bullying seriously and not just brush it off as something that kids have to tolerate. The effects can be serious and affect kids' sense of safety and self-worth. In severe cases, bullying has contributed to tragedies, such as suicides and school shootings.

Kids bully for a variety of reasons. Sometimes they pick on kids because they need a victim—someone who seems emotionally or physically weaker, or just acts or appears different in some way—to feel more important, popular, or in control. Although some bullies are bigger or stronger than their victims, that's not always the case.

Sometimes kids bully others because that's the way they've been treated. They may think their behavior is normal because they come from families or other settings where everyone regularly gets angry and shouts or calls each other names.

Unless your child tells you about bullying—or has visible injuries—it can be difficult to figure out if its happening.
