On one such day,I was walking from class across the school to catch the school bus home,with my head down,fighting tears of total hopelessness,when a young man came down the sidewalk toward me.Though I had never seen him before,I did not want him to see that I was in such low spirits,so I turned my head away and hoped to hurry past.I thought he'd walk on by,but he moved until he was directly in front of me,waited until I looked up,and then smiled.

    Looking into my eyes,this stranger spoke in a quiet voice："Whatever is wrong will pass.You're going to be OK,just hang on."   He,then,smiled again and walked away.

    I can't explain the effect of that man's unexpected kindness and caring! He gave me the one thing that I'd lost completely—hope.I looked for him in our school to thank him,but never saw him again.

    That was thirty years ago.And I've never forgotten that moment.Over the years,whenever I see someone who is in trouble,I will always think of that young man and try to give a flash of hope in the dark wherever I can.I carry things for people when they are too heavy for them,sit with naughty babies in the waiting room while their mothers are busy,or talk to tired couples at the checkout line or it could be anything.

    If you keep your head up,your heart will show you the place that needs hope.

    The weather is getting hotter. You are thirsty playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you are drinking. Something that looks cool may not be good for your health.

    There are plenty of “energy drinks” on the market. Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health. Sounds great!

    But after a careful check you may find that most energy drinks have lots of caffeine(咖啡碱)in them. These drinks are especially aimed at young people, students, busy people and sports players. Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much. Caffeine makes your heart beat fast. Because of this, the International Olympic Committee(IOC) has limited(限制) its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea.

    Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.

    Too much work and too much wine go together like biscuits and cheese, a new international studies finds. Employees who work more than 48 hours a week are 11 percent more likely to over-consume (过渡消费) alcohol than those who work standard time, Finnish researchers say. The study looked at more than 300,000 people in Australia, Europe and North America. No differences were seen between men and women, says the study, published in the British Medical Journal.

    Risky alcohol consumption is considered as more than 14 drinks a week for women and more than 21 drinks a week for men. About 20 percent of Australians drink at levels that put them at risk of lifetime harm from injury or disease. Drinking alcohol can affect the liver or cause brain damage, heart disease, high blood pressure and increase the risk of many cancers.

    Study author Marianna Virtanen said while alcohol might help ease the stress of working long periods of time, risky consumption could lead to difficulties in the workplace, such as poor performance. The European Union Working Time Directive ensures that workers in EU countries have the right to work no more than 48 hours a week, including overtime. “ But many people , for example well-educated managers and professionals, work much longer hours to achieve faster promotions (晋升), salary increases, and more control over work and employment,” said Prof. Virtanen from the Finnish Institute of Occupational Health.

    In many countries, schools have long summer holidays, with shorter holidays in between. However, a new report suggests shortening school holidays to stop children forgetting what they have learnt during the long summer break. Instead of three school terms, it says, there should be five eight-week terms. And there should be just four weeks off in the summer, with a two-week break between the other terms.

    Sonia Montero has two children at primary school and works full-time. She supports the idea. “The kids,” she says, “have much longer holidays than me and I can't afford to take several weeks off work, so I need someone to take care of them. But nobody wants the work in the summer months — they all have holidays of their own.”

    Not surprisingly, some young people disagree. Student Jason Panos says “It's a stupid idea. I would hate staying at school in the summer. It's unfair, too. The people who suggest this had long school holidays when they were young, but now they want to stop us enjoying the summer. The kids in Spain and America have much longer holidays than here, but they don't forget everything they've learnt in a few months.”

    Nadia Salib agrees. “Sure,” she says, “the first week at school after the summer is never easy, but you soon get back into it. The real problem round here is that kids get bored after so many weeks out of school, and then some of them start causing trouble. But the answer is to give them something to do, not make everyone stay in school longer.”

    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.
