Your school asked parents about the social development in children in the last Parents' Meeting. Here are some opinions. Read following information and answer the questions.

    We always knew our daughter Kendall was going to be a performer of some sort. She entertained people in our small town by putting on shows on our front porch when she was only three or four. Blonde-haired, blue-eyed, and beautiful, she sang like a little angel.

    When Kendall was five, we began to notice that she was blinking a lot and clearing her throat frequently. We took her to our local children's hospital where she was diagnosed with Tourette's Syndrome.

    It was pretty devastating（毁灭性的）because other children constantly made fun of her, and sadly, even a teacher teased her. Through all this, Kendall continued to sing and entertain. Remarkably, her tics disappeared when she sang.

    In 2005 when Kendall was sixteen, we thought she was pretty much out of the woods -- or at least heading in that direction. However, a freak accident happened.

    At a birthday party, Kendall hopped on a friend for a piggyback ride. Kendall flew over his back and landed on the cement floor -- on her neck. An ambulance rushed her to the hospital where she spent the next week, paralyzed from the neck down. Ironically, her biggest concern wasn't whether she would walk again, but whether she would be able to audition（试唱）for American Idol.

    Doctors said Kendall had central cord syndrome. Sometimes the pain was so unbearable that she had to bite down on a toothbrush to take her mind off it. As the days dragged on, we didn't know for sure how much of her movement would ever come back.

    I believe Kendall wanted the American Idol audition so much that she willed herself to move again. One of her friends brought a microphone to the hospital and put it on her bed. Every day, Kendall tried hard to pick it up with her right hand. It was more important for her to pick up that microphone than a spoon or fork.

    Sometimes we all cried because of the pain we witnessed. But on the day Kendall walked into the stadium to audition for American Idol – a mere three months after her accident -- we cried tears of joy. And our tears turned into shouts when she was given a golden ticket to Hollywood.

    Kendall is eighteen now, living every day to its fullest. She's recorded a CD with some of John Mellencamp's band members. I'm absolutely sure she's going to make it big some day. Kendall just puts it all in God's hands.

    When she was a little girl trying hard to be strong, she looked up at me, her big eyes brimming with tears, and asked me why she had to have Tourette's Syndrome. My heart ached to make the word right for my child. But I looked right back at her and told her the truth as I see it.

    “Kendall, God gave you a pure heart, an angelic voice, a strong mind, and a beautiful presence. With all of that, he had to make it fair for everyone else.”

    The weather symbol shown for each day in the five day forecast represents the main weather expected on the day in question. The maximum temperature is the highest temperature forecast between dawn and dusk, whereas the minimum temperature is the lowest temperature expected from dusk on the day to dawn the following day. The wind speed and direction are the expected conditions at midday.

    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.

Babies made from three people approved in UK

    Babies made from two women and one man have been approved by the UK's fertility regulator. The historic and controversial move is to prevent children from being born with deadly genetic diseases.

    Doctors in Newcastle — who developed the advanced form of In Vitro Fertilization or IVF (人工授精) — are expected to be the first to offer the procedure and have already appealed for donor eggs. The first such child could be born, at the earliest, by the end of 2017.

    Some families have lost multiple children to incurable mitochondrial (线粒体的) diseases, which can leave people with insufficient energy to keep their heart beating.

    The diseases are passed down from only the mother, so a technique using a donor egg as well as the mother's egg and father's sperm has been developed.

    The resulting child has a tiny amount of their DNA from the donor, but the procedure is legal and reviews say it is ethical (伦理的) and scientifically ready.

    "It is a decision of historic importance," said Sally Cheshire, chairwoman of the Human Fertilisation and Embryology Authority (HFEA). "I'm sure patients will be really pleased by what we've decided today."

    But some scientists have questioned the ethics of the technique, saying it could open the door to genetically-modified(转基因) 'designer' babies.

    The HFEA must approve every clinic and every patient before the procedure can take place. Three-person babies have been allowed only in cases where the risk of a child developing mitochondrial disease is very high.

    Prof Mary Herbert, from the Newcastle Fertility Centre, said, "It is enormously pleasing that our many years of research in this area can finally be applied to help families affected by these devastating diseases".

    "Now that we are moving forward towards clinical treatments, we will also need donors to donate eggs for use in treatment to prevent affected women transmitting disease to their children."

    Prof Sir Doug Turnbull, the director of the Welcome Centre for Mitochondrial Research at Newcastle University, said, "We are delighted by today's decision. We will also provide long-term follow up of any children born."

    NHS England has agreed to fund the treatment costs of the first trial of three-person IVF for those women who meet the HFEA criteria, as long as they agree to long-term follow up of their children after they are born.
