    Two weeks before my 12th birthday, my teacher asked me to conduct an experiment. When I mixed some powder together, they exploded. Molten liquid hit me in the face, but I felt no pain.

    I vividly remember standing there in a state of calm. I thought I was in a dream, but however hard I struggled to swim to the surface of consciousness, I couldn't wake up. I didn't understand how terrifying it was until I heard people saying, ＂Who's that?＂ That's when I knew I was unrecognizable.

    I was taken to hospital, but the doctors didn't know what to do with me. Later I was flown to Houston for surgery. Between the ages of 13 and 16, I had 40 operations. As each operation came and went, my vision would come back, then fade again. Eventually, it faded completely and I had what was left of my eyes removed for cosmetic reasons.

    Since then, I have lived in total darkness. Most blind people, even if they don't have any sight they're aware of, are still able to sense light. That gives them a sense of day and night. But not me. I absolutely lost that sense of time passing.

    For many years, I felt my sight loss darkening my life like the loss of my parents from which I would never recover. But when I was in my 40s, I realized I had to find a way to live. I trained to become a counselor, and that has helped me see my experiences in a different way. I can't fix people's broken lives — just like I can't fix my sight — but I can help them find a way to manage.

    Sometimes it feels as if all the struggles and negative experiences I've lived through were in fact a kind of preparation for helping others to make their own way towards the light.

Jennifer Fish, a weather forecaster may soon be replaced by something truly fishier—the shark.

    Research by a British biology student suggests that sharks could be used to predict storms.

    Laura Smith, 24, is close to completing her study on shark's ability to sense pressure.

    If her studies prove the theory, scientists may be able to monitor the behaviour of sharks to predict bad weather.

    Miss Smith had previously studied the behaviour of lemon sharks in the Bahamas.

    She then used their close relatives, lesser spotted dogfish (猫鲨), for further research at Aberdeen University.

Her work—thought to be the first of its kind to test the pressure theory—resulted from the observation that juvenile blacktip sharks off Florida moved into deeper water ahead of a violent storm in 2001.

    Miss Smith said: “I've always been crazy about traveling and diving and this led me to an interest in sharks.”

“I was delighted to have been able to research in the area for my degree. I know there's so much more we need to understand—but it certainly opens the way to more research.”

    It has been discovered that a shark senses pressure using hair cells in its balance system.

    At the Bimini Shark Lab in the Bahamas, Miss Smith fixed hi-tech sensors to sharks to record pressure and temperature, while also tracking them using GPS (Global Positioning System) technology.

In Aberdeen, she was able to study the effects of tidal (潮汐的) and temperature changes on dogfish—none of which were harmed. She also used a special lab which can mimic (模拟) oceanic pressure changes caused by weather fronts.

    She is due to complete her study and graduate later this year. She says she will be looking for a job which will give her the chance to enrich her experience of shark research.

    Buying new clothes isn't an easy matter for everyone, here are some tips(建议) for you .When you want to go shopping, decide how much money you can spend on new clothes. Think about the kind of clothes you really need. Then look for those clothes you really need. Then look for those clothes on sale.

    There are labels(标签) inside all new clothes. The labels tell you how to take care of your clothes. The label for a shirt may tell you to wash it in warm water. A sweater label may tell you to wash in cold water. The label on a coat may say "dry clean only", for washing may ruin this coat. If you do as the directions(说明)on the label, you can keep your clothes looking their best for a long time.

    Many clothes today must be dry cleaned. Dry cleaning is expensive. When buying new clothes, check to see if they will need to be dry cleaned. You will save money if you buy clothes that can be washed.

    You can save money if you buy clothes that are well-made. Well-made clothes last longer. They look good even after they have been washed many times. Clothes that cost more money are not necessarily better made. They do not always fit better. Sometimes less expensive clothes look and fit better than more expensive clothes.

    For centuries, mankind and dogs have suffered from a communication failure. We can tell dogs what we want them to do and sometimes they comply, but we've always struggled when it comes to understanding the true meaning of their barks and whimpers. There is exciting news now – a dog translator has been invented to help you communicate with your furry friend.

    Researchers at North Carolina State University have fashioned some kind of miracle dog translator body harness(束腰带). What's special about it is that it doesn't just rely on the dog's vocalizations to interpret what Fido is banging on about.

    Oh no – this miracle harness reads and interprets the ordinary dogs' body language as well, giving us a full two-way dog communication experience.

    Researcher David Roberts says: "Dogs communicate primarily through body language, and one of our challenges was to develop sensors that tell us about their behavior by observing their posture remotely."

    Sensors on the harness monitor the dog's heart rate and body temperature and software builds up a vocabulary, letting the human know what the dog is feeling.

    What would dogs say if they could talk to us? The human can even communicate back through the harness thanks to vibration motors, supposedly by tapping into the dog's senses so that it can understand what you're trying to say to it.

    The dog harness is designed for dogs involved in search and rescue and other front-line work, but it's got us dreaming of a beautiful future, one where humans and dogs can co-exist as equals, with the dog able to fully express itself at all times.

    A day in the life of 18­year­old David Lanster is full of typical teenage stuff: school, baseball practice and homework. And then he starts cooking. "Some nights I'm up until 1: 00 a. m. making pies, or even later if we're cooking beef," said the student at Ransom Everglades High School in Florida, US.

    For the past year, Lanster and Kelly Moran, his classmate, have been hosting fancy dinner parties at Lanster's parents' home. Their meals have 17 courses and are all made by themselves. Their guests used to give them gifts to thank them until the pair decided to do something nice for charity. "We got some really great Miami Heat tickets, a nice watch, and many kitchen gadgets (小器具)," Lanster said. "But we wanted to make this something positive for people other than us."

    Lanster and Moran focus on Common Threads, a charity that aims to teach kids in poor communities to cook and make healthy eating choices. The young cooks ask their guests to give however much they want as payment for their meals. It all goes to Common Threads because Lanster's parents cover their food costs. After their last 12­person event, Lanster and Moran gave $1,600 to the charity.

    Now, they're taking their show out of the kitchen and on the road. They have started to organize private dinner parties with a similar model: the host pays for the ingredients, and the guests make a donation to a charity of their choice.

    Without formal training, Lanster said he had been interested in cooking since he helped his mom in the kitchen when he was very young. He learned how to cook by reading cookbooks and watching TV programs. Outside the kitchen, the two are busy preparing their college applications. Neither of them is sure what they will do in the future, but they've promised their parents that they will leave professional cooking alone until they finish school.

Planning Your Family Trip

    Plan ahead to make your family trip run smoothly. Family vacations are cherished memories. Keeping children entertained on the road or during a flight, however, can be challenging. The best way to cut down on anxiety? Plan ahead.

    Avoid giving children snacks that contain sugar and caffeine. Sweet treats keep them happy and quiet for five minutes, as it fills them with unusable energy that will turn into crankiness (偏执) when the sugar wears off. Bring fun, small snacks like flavored baked chips, apple sauce, raisins, and granola bars—and top it off with a little protein like cheese sticks to keep the blood sugar levels nice and steady.

    Bring plenty of plastic or paper bags. This is the perfect time to put those spare bags around the house to use. Store them in your purse or pocket, as well as in the car. This is a quick solution for garbage, diaper wrapping or motion sickness.

    Avoid extra costs on bulk items you will need during the trip. When flying, purchase bulk items like diapers, formula, and wipes at your destination. In the past, it was convenient and free to check these items. Now, each checked luggage item costs $25 or more on average. When driving, do the opposite; take your bulk items to avoid extra trips to the store when you arrive, which can help you avoid impulse travel purchases.

    Bring a full change of clothing for each child. Keep these items within fairly easy reach. When a spill or mess happens, this will help parents avoid unexpected (and unbudgeted) clothing purchases.

    Travel planning can help make family vacations what they are supposed to be: Fun! What are some of your favorite strategies for saving time and stress while traveling with children?
