In summer, millions of people will head for the beach．And while the ocean can be a great place to swim and play, it may also be useful in another way. Some scientists think that waves could help make electricity．

    “Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave? Or have you jumped in the water and felt the energy as waves crashed over you?” asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh in Scotland．“There is certainly a lot of energy in waves．”

    Scientists are working on using that energy to make electricity．Most waves are created when winds blow across the ocean．“The winds start out by making little ripples (波纹) in the water, but if they keep on blowing , those ripples get bigger and bigger and turn into waves, ” Taylor said．“Waves are one of nature's ways of picking up energy and then sending it off on a journey．”

    When waves come towards the shore, people can set up dams or other barricades to block the water and send it through a large wheel called a turbine (涡轮) ．The turbine can then power an electrical generator (发电机) ．

    The United States and a few other countries have started doing research on wave energy , and it is already being used in Scotland．

    The resource is huge．We will never run out of wave power, besides, wave energy does not create the same pollution as other energy sources, such as oil and coal．

    Oceans cover three quarters of the earth's surface．That would make wave power seem perfect for creating energy around the world．There are some drawbacks, however．

    Jamie Taylor said that wave power still cost too much money．He said that its effects on animals in the sea were still unknown．Plus, wave power would get in the way of fishing and boat traffic．

    With more research, however, “many of these problems might be overcome,” Taylor said．“Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is growing quickly throughout the world．Finding more energy sources is very important, for traditional sources of energy like oil and gas may run out some day．”

    In the future, when you turn on a light switch, an ocean wave could be providing the electricity!

    Today's museums include plenty of high culture, but you can still find shrines（圣地）to the extraordinary. Here's a look at five curious museum stops across Canada.

Vancouver Police Museum

    The setting, terrible enough, is the old Coroner's（验尸官）Court and forensics lab, including the morgue(room where dead bodies are kept). Artifacts, from the 1870s on, include badges, uniforms, police equipment, items from criminals, and even preserved organs—all in all an arresting experience.

Vulcan Tourism & Trek Station

    Designed to resemble a spacecraft, the Treck Station celebrates Vulcan's coincidental relationship to Mr. Spock's planet, Go to a building that features an 800-piece collection of Star Trek memorabilia — including Spock's ears and floor-to-ceiling space paintings.

Accordion（手风琴）Museum

    Through instruments, photos and recordings, the museum traces the history of the accordion and its influence on Quebec culture. They've even acquired Asian instruments that show the use of the free reed— call them ancient ancestors of the accordion—that date back 4000 years.

Chocolate Museum

    It's chocoholic heaven — whole museum featuring displays on how chocolate is made, hands-on exhibits, collections of historic chocolate boxes, and antique candy- making equipment and, of course, lots of chocolate treats ,located in an old candy factory building. Click below to learn all about their hours and admission rates. http:// www. Chocolate museum .com

Potato museum

    A 14--foot high potato greets you at what's billed as the world's largest exhibit of potato artifacts. Explore the humble potato's role in the economy, a collection of farm tools related to growing and harvesting potatoes, Hall of Fame.

    Sally Dawly is a woman from Auburn, California. Over the last three and a half years, the anti-littering woman has spent most of her free time picking up cigarette butts (烟头) from the streets of her home city.

    Called the "Butt Lady" by her local community, Dawly began her mission to rid the streets of her city of cigarette butts in October, 2014. The woman looked for cigarette butts, picked them up and threw them in the trash. To keep a count of how many butts she picks up, the Butt Lady has been using a tablet, and earlier this month, she hit a historic milestone—one million cigarette butts.

    "I got tired of going on my walks and seeing cigarette butts everywhere," Sally Dawly said. "I'm just shocked that I had to pick up so many. I've ever picked up 3,000 butts in one day," she said. "Don't throw away your butts; better yet, stop smoking."

    With so many cigarette butts littering the streets, can one person's efforts really make a difference? Surprisingly, the answer seems to be yes. Soon after the Butt Lady of Auburn started her mission and word of her efforts spread, cigarette cans started appearing around bars and restaurants in the city. Members of the local community even came out to cheer her on as she approached her one-million-butt milestone.

    Sally knows her city's cigarette butt littering problem won't be solved anytime soon, but she hopes her work will inspire people to at least think twice before dropping cigarette butts in the streets. She has decided to continue cleaning up after irresponsible smokers, and already has a new milestone in her sights—two million cigarette butts.

    Word of the Butt Lady's efforts to keep the streets cigarette butt-free has reached neighboring communities as well, and CBS Sacramento reports that other cities have started seeking her help as well.

    A company in San Francisco, California, has found a way to turn used plastic bottles into women's shoes.

    Every day, millions of Americans drink water and other liquids from plastic bottles. More than 60 million of them are thrown away each day. Many of the plastic bottles end up in landfills or are burned with other waste products.

    A San Francisco start-up company called Rothy's, however, turns this plastic waste into environmentally friendly shoes. Roth Martin is the company's co-founder. He explains how they turn plastic into soft material for women's feet. They take the plastic, clean it, and break it down into small pieces. Then they press them through a device that makes soft fibers. Those fibers are then combined together. This is done by a 3D machine. It is designed to reduce waste while making the shoes. The knitted stuff and the inner part of the shoe are then attached to the shoe's outer part, called the sole (鞋底). This outer sole is also made from environmentally friendly material: responsibly sourced no-carbon rubber.

    Rothy's shoes are sold online. They are flat shoes, with either a rounded or pointed toe. They come in different colors and designs. They cost either $ 125 or $ 145 per pair, depending on the design. After American actress Gwyneth Paltrow discovered them last year, the demand for the shoes grew. Martin says there is no shortage of material to fill that demand. "We're not going to run out of water bottles any time soon. So we have a limitless supply of material, and I think that is a good sign for our future." When the environmentally friendly shoes wear out, customers can return them at no cost to a company that uses the recycled materials to make other products.

    For now, the shoes are only available to be shipped in the United States. However, the company says it will add international shipping in the near future.

    Most of the time, people wear hats to protect themselves from harsh weather conditions. Hats are also worn to show politeness and as signs of social position. But nowadays, hats, especially women's hats, are much more than that. More exactly, hats have changed into fashion and style symbols by many movie stars. What's more, people now consider many different features when choosing even a simple hat. Many designers point out that, when choosing the right hat, it's important to consider the color of your skin as well as your hair, your height, and the shape of your face.

    First of all, the color of the hat should match the color of your skin and hair. For instance, black hats should be avoided if you are dark skinned. If a purple hat is placed on top of red hair, one will look as attractive as a summer flower. Second, the height of the hat is also an important point. Tall women should not go for hats with tall crowns, just as short women should choose hats with upturned brims to give the look of height. Third, and most importantly, the shape of the face decides the kind of hat one should pick. A small, gentle hat that fits the head looks good on a small face. However, women with big, round faces should choose a different style.

As the saying goes, "Fine feathers make fine birds." A good hat can not only help your dress but also support your features, so why not choose the best possible one next time you want to be in public?
