When 19-year-old Sophia Giorgi said she was thinking of volunteering to help the Make-A-Wish Foundation (基金会)，nobody understood what she was talking about. But Sophia knew just how important Make – A –Wish could be because this special organization had helped to make a dream come true for one her best friends. We were interested in finding out more, so we went along to meet Sophia listen to what she had to say.

    Sophia told us that Make – A –Wish is a worldwide organization that started in the United States in 1980. ” It's a charity(慈善机构)that helps children who have got very serious illnesses. Make – A –Wish help children feel happy even though they are sick, by making their wishes and dreams come true, ” Sophia explained.

We asked Sophia how Make – A –Wish had first started. She said it had all begun with a very sick young boy called Chris, who had been dreaming for a long time of becoming a policeman. Sophia said lots of people had wanted to find a way to make Chris's dream come true —-so, with everybody's help, Chris, only seven years old at the time, had been a “policeman” for a day. ” when people saw how delighted Chris was when his dream came true, they decided to try and help other sick children too , and that was the beginning of Make – A –Wish, ” explained Sophia.

    Sophia also told us the Foundation tries to give children and their families a special, happy time. A Make-A-Wish volunteer visits the families and asks the children what they would wish for if they could have anything in the world. Sophia said the volunteers were important because they were the ones who helped to make the wishes come true. They do this either by providing things that are necessary, or by raising money or helping out in whatever way they can.

    A research project jointly carried out by scientists from several British universities and institutes has drawn people's attention to the toothbrush again.

    Researchers have found that your toothbrush is home to more than 100 million bacteria. But there are hundreds of microorganisms in the mouths and your toothbrush probably won't make you sick unless there is an unhealthy balance of bacteria. Our immune system can usually take care of bacterial invaders. However, if others use your toothbrush, or you use someone else's, bacteria can be spread.

    They have also found the toothbrush holders are the third-most dirty household items (behind dish sponges and kitchen sinks), thus advocating cleaning the toothbrush holder regularly.

    The storage of your toothbrush in your bathroom is also important. Here are some storage tips from the researchers to keep your toothbrush as healthy as possible:

    Put your toothbrush as far away as possible from the toilet flushing.

    Let your toothbrush dry thoroughly between brushings.

    Don't use toothbrush covers, which can create a perfect breeding ground for bacteria.

    Keep your toothbrush upright in a holder rather than lying down.

    Keep toothbrushes separate. If toothbrushes touch, they can exchange and spread bacteria.

    There are products available that claim to sanitize（消毒）your toothbrush. While some of these products do kill some bacteria, there is no evidence that using them will reduce your risk of illness, according to the researchers.

    They recommend replacing your toothbrush every three to four months or more often if you are sick or if you have a weakened immune system. Children's toothbrushes may need to be replaced more often than adult brushes.

    In 1999, 36­year­old Tori Murden McClure became the first woman to row also (单独地) across the Atlantic Ocean, from the Canary Islands to the Caribbean. The journey of just over 5,300 kilometers took the American 81 days. Her boat, The American Pearl, was only 7 meters long.

    McClure is a real adventurer. She has been on many mountaineering expeditions, including climbs in Alaska, Kenya and Antarctica. She was also the youngest person in a team that skied 1, 200 kilometers across Antarctica to the South Pole in 1989, and became one of only two women ever to travel to the Pole by land.

    The journey across the Atlantic was her third attempt. The first time she failed because of illness, and during her second attempt, in 1998, she nearly died. She had rowed nearly 5,000 kilometers when her boat was hit by Hurricane Danielle. McClure was suddenly in the middle of 80 kph wind, and surrounded by waves that were 20 meters high. Her little boat turned over five times. McClure was sure that she was going to die­she took the video recorder that she had brought with her and recorded a farewell message to her family and friends. The hurricane continued into night, and The American Pearl turned over five more times. McClure was determined not to send a signal asking to be rescued­she didn't want other people to risk their lives, too. But after the eleventh turning over of her boat, she finally sent it and a large ship came and found her. However, they couldn't get her boat out of the rough sea­it was found months later near the coast of Portugal.

    Tori McClure had concussion (脑震荡) and a dislocated shoulder when she got home. Many people might have given up after an experience such as this, but one year later, McClure was back in her repaired boat and trying again. This time she was successful­and although she again met a hurricane on the journey, which stopped her from breaking the record for the fastest transatlantic (横渡大西洋的) rowing crossing, she only overturned once!

Jim Curry lights a stove in the parking lot of Christ Episcopal Church in Guilford. It'll get up to 2,000 degrees, hot enough to soften the metal of shotgun parts so they can be reshaped.

A crowd is watching, and Curry picks out a 9-year-old named Oliver to help him. "This is really magic," Curry says. "Right before your very eyes, you're gonna see Oliver transform this gun, this instrument of potential harm, into something that could never be a gun ever again. It's gonna be a trowel (泥铲), which could be used to plant flowers in a garden."

"It is exciting," Oliver says. "I love the fact that you can take metal that's random and shape it into something useful."

Curry, a retired priest, is a co-founder of Swords to Plowshares (犁) Northeast, the organization putting on this event, which helps police departments manage their gun buyback programs and repurpose the weapons into gardening tools.

The finished tools are donated to community gardens and agricultural high schools and the harvested vegetables donated to soup kitchens and homeless shelters, according to the group's website.

Retired priest Mary Ann first volunteered with Swords to Plowshares when a family member fell victim to gun violence. She helps collect guns through police buybacks. "When there's such despair now in our country, people need to know that we can change. There is hope," she says.

Curry wears a constant reminder of that hope around his neck. It's two large pieces of metal molded into the shape of a cross. "It's made out of pieces of an AK-47 used for killing", he says. "But God's love breaks it apart, reshapes it, then transforms it into the sign of greatest hope — the cross. And that's why I wear it."

Max Du won the Canada-Wide Science Fair. His project is a drone (无人机) to save people who go into cardiac (心脏的) arrest. Max got the inspiration during Christmas break last year. "I got a toy drone from my parents, but I couldn't fly it because it is snowy." Max said. "So I played with it at home, and it got me thinking how a drone could be used as an indoor robot that could help people."

About 35, 000 people have cardiac arrests in Canada each year. Most of those happen outside of a hospital, of whom fewer than 10 percent survive. Max believed a drone could offer faster support and life-saving medicine, but he had to build it himself to know for sure.

Testing his drone took about six months. Max's parents had to deal with their son's constantly flying and crashing in the home. Every time Max would create an exciting innovation, such as an extendable arm, it would add extra weight to his drone, causing it to break apart. Then Max would have to buy all new parts. Max tested using more lightweight materials until his design was more balanced.

Through trial and error, the 14-year-old boy finally got it right. His drone can open a door handle, fly in the air and then land softly on the ground. A new extendable arm can be released to administer a shot or hand a patient lifesaving medicine. A built-in camera could directly conference with an emergency response team whose members could monitor the patient remotely.

Max plans on applying for a patent (专利) so he can make connections in the health-care industry to get it made for real. He's spent his summer learning about artificial intelligence at California's Stanford University as one of 32 kids selected worldwide. He'll head next to the University of Pennsylvania to take a college-level robotics class before returning to high school in September.
