When I was a boy my father told me that he could do anything he wanted to. Dad said that he wanted to be the first to develop color prints in our city and so he did．

        When I was 16，Dad looked closely at the violin I played and said that he wanted to make one．He read about violin-making, and then became a violin-maker at the age of 43. He bought the tools and materials, opened a small store and set Mom up as the shopkeeper, while he worked at a local company. He retired from the company 17 years later and continued to make violins and other instruments.

        Dad often guessed why the Stradivarius violins sounded so beautiful. Some experts told him that it was the special varnish(油漆)that gave the instruments their beautiful sound．Dad argued that chemists could analyze the varnish—if that was the answer．

One of Dad's friends asked him which kind of wood was used to make violins．When Dad explained that the top was made of spruce(云杉), his friend said that he had all old piece of spruce which Dad might be interested in.

He worked for the next 12 months making a violin from the wood that his friend had given him. It proved to be an excellent violin and it would become Dad's masterpiece. He believed that the secret of the Stradivarius sound was in the wood itself.

        Later, the instrument was stolen, Dad's spirit was broken and he stopped making instruments. But he kept the music shop until he was 80 years old, selling guitars and violins.

        The violin has been missing for more than 25 years．Somewhere a musician is playing a late-20th-century violin with an excellent tone．The owner today may never understand why this Ordinary-looking violin sounds so much like Stradivarius．

    Dolphins(海豚) live in a dark underwater world. It's often impossible to see each other or anything else around them, so sound plays an important role in their survival. To communicate with each other, dolphins produce all kinds of sounds.

    Only other dolphins understand what the sounds mean. Scientists haven't uncovered their secret communication, except for one kind of whistle. It might last less than a second, but this whistle is a big deal. Why? Because these whistles are actually names of dolphins - and every dolphin has one. Scientists call these sounds a “signature whistle.” When other dolphins hear the whistle, they know which dolphin is calling.

    Dolphins often hunt by themselves but still need to stay connected to the group. Since they can't always see each other, dolphins use their signature whistles to check in with other dolphins hundreds of yards away. “In coastal areas, dolphins exchange whistles even when they're a third of a mile apart,” says Greg Campbell, who studies animals. That means dolphins shout out to group members that might be nearly five football fields away.

    What's amazing is who names the baby dolphin. Not the mother. Not an auntie dolphin or another group member. Scientists believe the baby dolphin itself comes up with the signature whistle. Like human babies, a baby dolphin plays with sounds throughout its first year. While testing its sound skills, a baby dolphin is doing something amazing. It's creating or figuring out its signature whistle. How or why it chooses its signature whistle is not clear. Studies show that most of the time the signature whistle is nothing like its mother's or group members' whistles.

    When the baby dolphin is about a year old, its signature whistle is set. It repeats it often so the other dolphins learn to recognize it.

    Deciphering(破译) dolphin names is just the beginning of figuring out what dolphins communicate about. Do they chat about sharks? Discuss the tides? Maybe they even have a name for people. Someday scientists are to decipher the rest of dolphins' communication.

    There have always been a lot of commonly believed but false ideas about being fat and doing exercise. Some people believe that they can't help putting on weight as they get older, while others hold that if they stop exercising, their muscles will turn into fat. Here are some more myths：

    I'll never lose weight—I come from a fat family

    Wrong! While we can't change the body type we are born with, we can't blame our genes for making us fat. There's plenty of evidence that fatness runs in families, and the main reason is that they share the same habits of eating too much and exercising too little.

    I am fat because I burn calories slowly

    Wrong! Fatness is not caused by a slow metabolism(新陈代谢). In fact, although fat people consume more energy than slim people, they also fail to realize how much they eat! Keeping a diary can help you work out your daily food intake more accurately.

    Exercise is boring

    Wrong! Anything will become boring if you do it repetitively. The key is to develop a balanced and varied programme that's fun as well as progressive. If you enjoy a Sunday walk, take a different route. If you do yoga, try a tai chi class. If you like swimming, set yourself a distance or time challenge.

    No pain, no gain

    Wrong! Exercise is not meant to hurt. Indeed, pain is your body telling you something's wrong, and continuing to exercise could lead to serious injury. You may experience mild discomfort as you begin to exercise regularly, but this is your body adapting to the positive changes in your lifestyle and the aches should disappear relatively quickly. If they don't, rest and seek medical advice.

    The weather outside might be freezing at home, but that doesn't mean you have to spend the winter shivering. Instead, grab your bathing suit and sunscreen and head to these sunny spots that offer the best warm-weather getaways for every interest.

    The best city beaches: San Juan, Puerto Rico

    Being able to relax on a warm sandy beach in the middle of the winter is obviously a dream getaway, but not everyone wants their sand and surf to be hidden in a remote comer of an island. Instead, head to the sizzling（炎热的）city nightlife of San Juan, where the streets of chic Condado back right into the palm trees and lapping waves of the Atlantic beaches. Top chefs, stylish hotels, bars ， clubs, and shops are all just steps away from the tropical beaches. And since Puerto Rico is a United States Commonwealth, it's one of the easiest islands in the Caribbean to visit since you won't need a passport, have to change money, or even worry about your cell phone working. Puerto Rico is also one of the best tropical vacations you can take without leaving the United States.

    The best swimming holes: Riviera Maya, Mexico

    What's better than diving into the salty sea? Submerging in the crystal clear and salt-free waters of the naturally occurring limestone cenotes of the Riviera Maya and Yucatan Peninsula. Spend a sunny day exploring these natural cave pools filled cool filtered water that springs from the ground below and the lush palm forests that surround them. Then head back to the perfectly located Fairmont Mayakoba for comfortable rooms and modem Mexican cuisine.

    The best girlfriend getaways: New Orleans

    New Orleans vibrant nightlife and live-music scenes make the “Big Easy” a great girl's trip winter getaway (check out the Girl's Trip movie if you don't believe us). And even if your crew isn't one to seek out the boozy Bourbon Street crawl, there's plenty of amazing food to be discovered in the French Quarter, plenty of shopping and strolling in the Garden District, and warm weather cruises along the bayou, too. Check out these other great weekend getaways for girls trips.

    The best aquatic movie star-spotting: Clearwater, Florida

    If you want to meet a real movie star while also soaking up the sun, head to the Gulf shores of Clearwater, Florida. Here you can meet the stars of Dolphin Tale and Dolphin Tale 2, Winter and Hope, who are in residence full-time at the Clearwater Marine Aquarium. The amazing dolphins will probably make you want to hit the waves yourself, which won't be a problem since the beautiful white sand beaches here boast 361 days of sunshine per year. Next, don't miss these destinations that are even better in the winter.

    As we all know, there are plenty of different parks to visit in the UK. All theme parks in Britain have cafes, restaurants, picnic areas and gift shops, so you'll still have plenty to see and do when you and the kids have been on enough rides. There are usually smaller "funfair" rides and games as well, so younger children won't get bored. Several theme parks also have other attractions next to them, e. g. water parks often open all year round, unlike the theme parks.

    Whenever you are in Britain, there's likely to be a theme park within one or two hours' drive, bus ride or train journey. Several theme parks even have accommodation(膳宿)so you can stay for a day for two if you want to make a trip into a short holiday.

    Prices for UK theme parks vary considerably; some have an entrance price which allows you to go on all the rides, while in others you have to pay for every ride individually. It can also make a difference whether you go during peak time or not. For example, tickets always cost more during school holidays and weekends than they do during the weekdays.

    Theme parks always get very busy during the summer months, so if you don't like crowds it's usually a good idea to go earlier or later in the year!

    If you're thinking of visiting a UK theme park, it's worth having a look for special offers on tickets. Products such as chocolate bars and cereals sometimes have "buy one get one free" offers on theme park tickets, so keep a look out in shops and supermarkets.
