How Bad Are Energy Drinks for Children?

    What Are Energy Drinks?

    There is no clear definition of what makes an energy drink, but it is usually taken that anything non alcoholic with more than 150mg of caffeine per litre is an energy drink. The first of its kind was Lucozade, which was launched in 1927. It was promoted as helping the sick to get better by regaining lost energy. Now there are lots of energy drinks on the market, all claiming to help boost energy levels and aid our performance.

    What's in Energy Drinks?

    We've mentioned the caffeine but energy drinks also contain water and sugar. Some also contain alts and amino acids.

    What Are the Health Concerns?

    The concerns focus on the two main ingredients (成分) of energy drinks, caffeine and sugar. Too much caffeine for children can in the short term cause headaches and raise blood pressure although it is important to mention that caffeine may not harm children in the long term. However, the short term issues do really worry teachers as caffeine can lead to an inability to sleep, which then affects a child's ability to focus and concentrate in class. In fact the maximum recommended (推荐) intake of caffeine for children is 2.5mg for every kilogram a child weighs, so if a child drinks energy drinks, it would be very easy to go over this dose.

    Too much sugar can also cause health problems including obesity, tooth decay and in the long run Type 2 diabetes. So as with caffeine, if children are drinking energy drinks and consuming sugar in foods and other drinks, then it would be easy to go over the daily sugar allowance for a child. The thing to be aware of is what is called free sugars. Free sugars are those sugars which are added to foods or drinks, not the natural sugar found in fruits and vegetables. The amount of free sugar that a child should have is 19 grams per day for those aged 4-6 and 24 grams for those aged 7-10. So again it is easy to see that if children are drinking energy drinks over and above sugar that will be present in food they eat, it would be easy to go over the recommended amount of sugar each day.

    Selling Energy Drinks to Children

    There are currently voluntary bans for shops not to sell energy drinks to children under 16, but there are calls to make this illegal. Some schools have already banned children from bringing these drinks into school.

(1)、What do energy drinks claim to do? (不多于9个词)
(2)、Why are teachers worried about too much caffeine in energy drinks?
(3)、What is the recommended amount of free sugar for an8-year一old child? (不多于2个词)

    The universe has never failed to catch human's attention. The ancient humans came up with stories to explain the presence of the suns and other planets.

Time for Americans to act on climate change

    The climate crisis is worsening at a rate that is becoming harder and harder to ignore. For more than two decades, scientific reports have made it clear that global warming is real, that humans cause it and that the consequences will be disastrous.

    The scientific community has become increasingly panicked over the past year. The latest assessment from the U.N. Intergovernmental Panel on Climate Change painted a far more terrible picture than its previous analyses, and the long-awaited National Climate Assessment made clear that climate change represents a severe threat to human health as well as our economic security. Out of this panic came the treaty(条约)reached this past weekend by world leaders to keep the Paris climate agreement alive.

    Yet many Americans still don't regard the threat as a key priority for our government, and support President Trump's decision to withdraw from the Paris treaty. Campaign contributions from fossil fuel companies have convinced elected officials to look the other way. A certain amount of despair has resulted in widespread apathy(漠然).

    But there is another reason that has been discussed far less openly. While a growing number of people understand that climate change will have significant worldwide consequences, many Americans have an intuitive(直觉的)belief that their nation is more capable than others of adapting to a changed environment. Why? Because they have before.

    This historical success, however, resulted from the federal government taking science seriously, and making investments to urge revolution and innovation.

    But these innovations did not happen by themselves, or simply because of the United States' rich resources. They depended on consistent support from the leaders about the need to take action when faced with crises. This has been especially true in the environmental crisis.

    President Bill Clinton had a shockingly modest record of advancing climate security, particularly given that his vice president, Al Gore, had been one of the most outspoken environmentalists in Congress. By far Clinton's biggest accomplishment was assigning Gore to participate іn thе Куоtо Рrоtoсоl negotiations. Сlіntоn сhоѕе, hоwеvеr, tо аvоіd whаt ѕurеlу wоuld have been a terrible fight in the Senate to gain approval of the treaty. While this effort probably would have failed, it would have signaled to the American people how seriously the Democratic Party took climate change.

    Thus, the time has clearly arrived for progressive candidates to start campaigning on a platform built around the need for a sustainability revolution. Such a plan should include a carbon tax, well-funded clean energy research, evolved agricultural policies and smarter public transport. Given that Generation X and millennials(千禧一代)never bought into the fiction that the United States is immune to the dangers of global warming, the time is ripe to make climate security a crucial government responsibility. Only by doing so can we begin the long-overdue(拖延好久的)campaign to save the planet.

Fighting the curse of presenteeism

    "It's true hard work never killed anybody, but I figure, why take the chance?" Beyond a certain level, extra effort seems to be self­defeating. Studies suggest that, after 10 hours a week, employee productivity falls sharply.

    But that doesn't stop some managers from demanding that workers stay chained to their desk for long periods. Jack Ma, the founder of Alibaba, recently applauded the "996" model, where employees work from 9am to 9pm, six days a week, as a huge blessing". However, to modern office workers presenteeism is a curse.

    There will be days when you do not have much to do, just waiting for someone else to respond to a request. As the clock ticks past 5pm, there may be no purpose in staying at your desk. But you can see your boss hard at work and, more important, they can see you. So you make an effort to look busy.

    If bosses do not like to go home before their underlings (下属)and underlings fear leaving before their bosses, everyone is trapped. Staff may feel that they will not get a pay rise, or a promotion, if they are not seen to be putting in maximum effort. This is easily confused with long hours. Managers, who are often no good at judging employees5 performance, use time in the office as a measurement.

    But presenteeism has more serious consequences. As well as reducing productivity, this can increase medical expenses for the employer. According to a study, these costs can be six time: higher for employers than the costs of absenteeism among workers. To take one example, research found that Japanese employees with lower­back pain were three times more likely to turn up for work than in Britain. As a result, those workers were more likely to experience greater pain and to suffer from depression. What could be more discouraging than being in pain while feeling trapped at work?

    "None of this is to say that employers are not entitled to expect workers to be in the office for a small amount of time. Unavoidably there will be a need for some (preferably short)meetings. Dealing with colleagues face-­to­-face develops friendships, allows for a useful exchange of ideas and enables workers to have a better sense of their common needs.

    With portable smart phones and laptops, we can work at home as easily as in the office. Turning an office into a prison does nothing for the creativity that is increasingly demanded of office workers as routine tasks are automatic. To be productive you need presence of mind, not being present in the flesh.

阅读下面短文,根据题目要求回答问题。

When I was at school, our teacher used to tell the class: "You are what you eat." Actually, he was trying to show us the importance of eating the right food to stay healthy. And there are clear proofs that you become what you eat.

Japanese people are considered to be the healthiest in the world because of the food they eat. Most of them eat rice and fish and vegetables every day. They drink green tea or water when they're thirsty, and snack on dried fish, fruit or ginkgo nuts. This tradition diet helps them live a longer and healthier life.

Food has great effect on our physical and emotional health. Have you ever heard any of the following advice?

·Lettuce(生菜)or milk can make you sleepy.

·To stop feeling sleepy, you should eat dried fish.

·To keep your teeth clean, you should eat apples often.

·Garlic helps you not to catch cold.

But some advice may be contradictory to each other. While some people say "eating chocolate makes you fat and gives you spots", some others say “chocolate contains the essential minerals like iron and magnesium(镁)." In this case, what you need to do is to figure out what type of chocolate and how much of it to eat.

Some restaurants have already had their menus list the nutritional content and the benefits of their dishes and drinks. Let's take the restaurant "Winners" as an example. Its dishes are specifically designed to help people win sports competitions. There is a typical Night before dish, a vegetable lasagne(宽面条)with rich tomato sauce full of vitamin and soft, easy-to-digest vegetables, which is lopped with a little fresh cheese—just enough to help you get a good night's sleep. Or you can choose the Go-faster salad, which is a large bowl of mixed raw vegetables in a light salad dressing. The vegetables are carefully chosen to include plenty of natural vitamins and minerals. It gives you energy without making you gain weight.

The concept of eating food only because it's tasty is going out of fashion. And food producers are changing. Cola companies are making sugar-free and caffeine-free drinks. Food companies are making cookies with dried fruit because it is healthier. So in the future you might be able to eat your way to your idea of perfection.
