There are 5.25 trillion pieces of plastic trash in the world's oceans, and each year, 8 million tons of plastic are added to the figure. Though the oceans seem vast enough to stomach a lot of plastic, the level of waste is starting to reach a crisis point: According to a new report by the Ocean Conservancy, by 2025, the ocean could contain one ton of plastic for every three tons of finfish.

All these floating bits of plastic not only disrupt marine ecosystems, but they also poison the global supply of seafood. “It's reaching crisis proportions,” says Andreas Merkl, CEO of the Ocean Conservancy. “Plastic breaks down into small pieces that look like plankton and is eaten by everyone from plankton to whales.” Plastic acts as a pollution sponge in the ocean, so when wildlife swallow pieces, the plastic might as well be a poison pill.

    The new report calls for a focus on improving waste management systems in a handful of developing countries that are most responsible for the plastic leakage into the ocean. China, Indonesia, the Philippines, Thailand and Vietnam contribute more than half of the oceans' plastic since their waste facilities hasn't kept up with rapid industrialization.

    On average, only about 40% of waste in these countries is actually picked up for disposal. But it's not just uncollected waste floating around-though that is three-fourths of the problem. The other quarter of the oceans' plastic came from post-collection activities. Even when a waste management company picks up waste to landfill it, poorly equipped landfills or illegal dumping mean that trash still ends up in the ocean.

    But how can countries stop the leakage of waste into the ocean? The Ocean Conservancy report suggests five “levers”: waste collection services, closing the leakage points within the collection system, gasification and burning of waste, and recycling facilities. The average waste ends up as litter. Just by expanding collection systems and plugging up their leakage points, the report says plastics leakage could by cut by 50% by 2020.

    It's not just an environmentalist's daydream. Coca-Cola and Dow Chemical, along with some other multinational companies have joined forces with Ocean Conservancy to fight ocean pollution. “We're committed to working toward a future of a plastic-free ocean. Companies don't make plastic with the intent of it ending up in the ocean, and we acknowledge the strong role industry must play in order to help eliminate ocean plastic waste by 2035.” Says Dow Packaging and Speciality Plastics' global sustainability director in a press release.

    Merkl emphasized that the countries can't recycle their way out of the problem. Only about 20% of the waste is valuable enough to be worth recycling: the rest, needs to be sent to sanitary landfills or waste-to-energy plants. “You have to concentrate on the fundamentals of waste management,” he says. And while building landfills and incinerators(焚化炉)across these developing countries might not be pretty, it's far more environmentally friendly than letting waste slide into the world's oceans.

    Driving in Canada is similar to driving in many parts of the United States. Distances and speeds, however, are posted in kilometers per hour and some signs, particularly in Quebec, may only be in French.

    Unless otherwise posted, the maximum (最大限度的) speed limit in Canada is 50km/hr in cities and 80km/hr on highways. On rural highways, the posted speed limit may be 100km/hr. It is illegal to take automobile radar detectors (汽车雷达检测器) into Quebec, Ontario, Manitoba, and the Yukon. Seat belt use is required by law for all passengers, and child car seats must be used by children under 40 pounds. Some provinces require drivers to keep their vehicles' headlights on during the day and some have banned (禁止) driving while using a hand-held cell phone. Motorcycles cannot share a lane (车道), and safety helmets for motorcycle riders and passengers are necessary. Running a red light is a serious crime throughout Canada and drivers are advised to stop before starting when a light turns green.

    Winter travel can be dangerous due to heavy snowfalls and icy conditions. Some roads and bridges are often closed in winter. Snow tires are required in some provinces. Travelers should also be careful about animals while driving at night in rural areas.

    Highway 401, from Detroit to Montreal, is one of the busiest highways in North America. It has been the scene of many deadly traffic accidents due to sudden and severe weather changes, high rates of speed, and heavy truck traffic. Thus drivers should be alert while travelling here.

    Tattoos (纹身) are becoming more and more common. But they are not a new thing. Scientists have found some frozen bodies from around 3,000 BC and their skin shows the marks of tattoos. For example, Otzi, the Iceman (the oldest body ever found), was discovered in the mountains of Austria. He had many different lines and crosses tattooed on his back and his knees.

    The most common places to get tattoos are the tops of the arms for men and the bottoms of the backs for women. Any mark can be used but there are some common ideas. Some people like to get animals, like dragons, birds and tigers. Other people like to get something written in a foreign language, so Chinese and Japanese words are common in America and the UK. If you can't read the language, make sure you get someone to check what they represent because the tattoo artist could write anything and you would never know.

    It is a big decision to get a tattoo because they are very difficult to remove. It is possible with expensive laser surgery (激光手术) but this is very painful and amazingly expensive and the skin will never be perfect afterwards. You want to do a test, to see how you look with a tattoo, you can get a temporary tattoo which disappears after about a month. This kind is very popular in India, where people often have them for festivals.

    In some countries, such as Japan and Korea, tattoos are still connected with law-breaking activities and it isn't normal to see a tattoo in public. In many places of Europe and America, most people don't care very much whether you have a tattoo or not, though there are some types of job where they don't like tattoos. But some Presidents of the USA have had them.

    Do you ever draw? Most of us don't. The reason we usually leave drawing to the artists is that we're not very good at it. Who wants to do anything they're bad at? {#blank#}1{#/blank#}. Studies have found drawing has many benefits, artist or not. Here are just a few reasons for picking up a pen or pencil of any kind.

    It pushes you to be patient. We're used to things happening fast these days. Drawing is not fast. {#blank#}2{#/blank#} That's OK, and as something comes together over time, you'll be reminded of the value of patience. Drawing is an object lesson that not everything good comes quickly, which is an easy thing to forget.

    {#blank#}3{#/blank#} A few of my drawings are really kind of great. Í can look at them with pride. But plenty of my little drawings ate nonsense or unfinished. It doesn't matter. I still have the experience of drawing and the benefits that brings. Even if you're not naturally "good" at drawing, you'll get better over time if you practice. {#blank#}4{#/blank#} Your drawing doesn't have to mean anything or do anything useful, Sometimes you will even fail. No big deal.

    It makes memories stick, I draw in order to capture (捕获) moments from my life. I'm not great at drawing, but that's not the point. Sometimes I draw the view from the window of my hotel room-whether it's a great view or not. Remember, the idea is to capture the moment, not create a masterpiece. Other times I draw from my dinner table. {#blank#}5{#/blank#}

    Over the centuries the French have lost a number of famous battles with the British. However, they've always felt superior in the kitchen. France has for centuries had a reputation for cooking excellence, and Britain for some of the worst cooking in the world. But according to a recent survey, that reputation may no longer reflect reality.

    In the survey, 71% of the Britons said they cook at home every day, while only 59% of the French said they cook daily. British home cooks spend more time cooking each week and also produce a greater variety of dishes than French home cooks.

    The reaction in London was predictably enthusiastic. British food has greatly improved since the 1990s. Once upon a time, the menu for many family meals would have been roast beef, potatoes and over-cooked vegetables, but not now. Home cooks are experimenting with the huge range of ingredients now available in British supermarkets and are preparing all kinds of new dishes, using the cookbooks that sell millions of copies every year. As a result, there's much more diversity in British food now, compared to French food, which tends to be very traditional.

    Some French people say that the survey did not show the whole picture. They agree that during the week French women don't cook as much as they used to because most of them work and don't have much time. They tend to buy ready-made or frozen dishes, but many of them make up for it on the weekend. There's also a difference between Paris and the countryside. It's true that people in Paris don't cook much, but elsewhere, cooking is still at the heart of daily life.

    For many French people, opinions about British food have not changed. When Bernard Blier, the food editor at a magazine, was asked about British food, he replied: "I don't go out of my way to try it. It is not very refined. You can say that I'm not a fan at all."
