Bottled water has become the choice for people who are healthy and thirsty. Bottled water is all over the world. But some say the planet's health, and people's health may be suffering from it.

    The idea that bottled water is safer for humans may not be true. The Natural Resources Defense Council of America said, “There is no promise that because water comes out of a bottle, it is cleaner or safer than water from the tap.” Another New York City-based action group added that some bottled water is “really just tap water in a bottle—sometimes more clean, sometimes not.”

    It is not proven that bottled water is better than tap water. Nick Reeves from the Chartered Institution of Water and Environmental Management said, “The high mineral content(含量) of some bottled water makes them not good for feeding babies and young children.” Also, most bottled water doesn't have fluoride(氟化物), which can make teeth stronger. Kids are drinking more bottled water and less fluoridated tap water, and some say that's behind the recent rise in bad teeth.

    Storing is another problem. Placed near heat, the plastic bottles can produce bad chemicals(化学物质) into the water.

    According to the Environmental Protection Agency, some 2.7 million tons of plastic are used worldwide to bottle water each year. The plastic can take between 400 and 1,000 years to break down.

    In terms of energy use, plastic bottles are also not cheap. One report said that if water and soft drink bottlers had used 10 percent recycled materials in their plastic bottles, they would have saved about 72 million gallons of gas.

    So, if you are worried about the effect of bottled water on the Earth, you can take the following steps.

●Drink from your tap. Unless your government warns against this, it should be fine.

●Get a container(容器). Carry your tap water in a steel or a lined drinking container, and clean it between uses.

●Keep it cool. Don't drink from a bottle that has been sitting in the sun, don't store it near chemicals, and don't reuse plastic bottles.

●Choose glass containers over plastic if possible. When finished, recycle!

Dear John,

    My name is Amber and I want to share my story with you because what you've shared about life and positive energy has changed my life. This past year has been one of the hardest for me. I felt I was stuck in a position that had nothing to do with what I wanted to do with my life. In January, after two years of being together, my boyfriend left me.

    I read your blog every morning as I drink my coffee at work, but it wasn't until this March that I told myself "no more negativity" as you taught readers in your blog.

    Since then I've got into new habits at work to keep my energy positive. When people walk in the front door, I'm the first face they see, so I smile big when I say "good morning" to them, especially on Mondays. Instead of waiting for someone to ask me for help, I offer it with an open mind. The CEO noticed my change and offered me the executive assistant position that I wanted.

   One of the biggest things I've taken to heart from your blog is changing my opinions on my job. Yes, it was not an important position, but when I was passionate （热情的） about it, I could make my life fulfilling.

    All in all, I have to thank you somehow for having the passion to help others because it truly is inspiring to me. So thank you so much, John. My life has changed because your words pointed me in the right direction, Take care!

Sincerely ,

Amber

    The Queen's English is now sounding less upper-class, a scientific study of the Queen's Christmas broadcasts had found. Researchers have studied each of her messages to the Commonwealth countries since 1952 to find out the change in her pronunciation from the noble Upper Received to the Standard Received.

    Jonathan Harrington, a professor at Germany's University of Munich, wanted to discover whether accent  changes recorded over the past half century would take place within one person. “As far as I know, there just is nobody else for whom there is this sort of broadcast records,” he said.

    He said the noble way of pronouncing vowels (元音) had gradually lost ground as the noble upper-class accent over the past years. “Her accent sounds slightly less noble than it did 50 years ago. But these are very, very small and slow changes that we don't notice from year to year.”

    “We may be able to relate it to changes in the social classes,” he told The Daily Telegraph, a British newspaper. “In 1952 she would have been heard saying ‘thet men in the bleck het'. Now it would be ‘that man in the black hat'. Similarly, she would have spoken of ‘citay ' and  ‘dutay' , rather than ‘citee' and ‘dutee' and ‘hame' rather than ‘home'. In the 1950s she would have been ‘lorst', but by the 1970s ‘lost'.”

    The Queen's broadcast is a personal message to the Commonwealth countries. Each Christmas, the 10-minute broadcast is put on TV at 3 pm in Britain as many families are recovering from their traditional turkey lunch.

    The results were published in the Journal of Phonetics.

    To travel abroad, we often meet the problem of what to take and how to take it. Take as little as possible. Choose clothes for your use in different kinds of situations and when you have made your final choice, take half of it! It's always a big problem to take too many things, and anyway if necessary, you can buy what you need in America. Things like jeans, T-shirts and other clothes are good buys in the US. If you hunt around you can usually find something on sale.

    Whatever baggage you take, make sure it is easy to take. Getting on and off buses and trains, even just changing planes, can be a test if your bags are too heavy or too many. The best way is to take one holdall, like a suitcase or a backpack, and then a smaller bag. Even when you have to check in your holdall, at the airport or bus station, you can keep all your money and documents by your side. It is also a good idea to keep a change of clothing in your shoulder bag in case your suitcase or backpack gets lost by an airline or a bus company.

The means you choose to travel around the US will depend on your money, you time and something else. Since there are certain discounts available to travelers who buy their tickets outside the US, it is a good idea to make travel plans before you go. Also, when you buy your tickets outside the US, you save the eight percent sales tax. Travel is like everything else in America—you have to shop around for the best busy. Never be afraid to ask for the cheapest fare. The clerk seldom offers you the cheapest one.

    It is widely accepted that nightmares (噩梦) are a reaction to negative experiences that happen during waking hours. However, some scientists believe that nightmares do have some real benefits. One 2017 study, for example, found that frequent nightmare sufferers rated themselves as more empathetic (有同理心的). They also displayed more of a tendency to unconsciously mirror other people through things like yawning People who have constant nightmares also tend to think further outside the box on psychoanalysis tasks. Some other researchers have found support for the idea that nightmares might be linked to creativity.

    People seeking cure for nightmares were not necessarily more fearful or anxious, but rather had a general sensitivity to all emotional experience. Sensitivity is the driving force behind intense dreams. Heightened sensitivity to threats or fear during the day results in nightmares, whereas heightened passion or excitement may result in positive dreams. And both these forms of dreams may feed back into waking life, perhaps increasing suffering after nightmares, or promoting social bonds and empathy after positive dreams.

    The effects go further still. This sensitivity overflows into awareness and thoughts －people who have a lot of nightmares experience a dreamlike quality to their waking thoughts. And this kind of thinking seems to give them a creative edge. For instance, studies show that such people tend to have greater creative talent and artistic express and people who often have nightmares also tend to have more positive dreams than the average person.

    The evidence points towards the idea that, rather than disturbing normal activity, people who are unfortunate in having a lot of nightmares also have a dreaming life that is at least as creative, positive and vivid as it can be distressing and terrifying. What's more, this imaginative richness is unlikely to be limited to sleep, but also is filled with waking thoughts and daydreams. Even after people wake up and shake off the nightmare, in other words, a mark of it stays behind, possessing them throughout the day.

    I have three kids and a great husband and I'm enjoying a career that I find challenging and fun. This feels like "Success" to the outside world. But there is still a voice in my heart asking if this is who I truly am. Only in silence do I hear the self and wonder who that person might be.

    So I booked a trip to find out. I travelled, for the first time, without my husband or kids. I went to Iceland with a friend, who shares an appreciation for wilderness and silence.

    For six days, we were immersed in wild, raw scenery and real weather—all kinds of weather. Climbing a mountain against rain and returning to a tent for a simple meal reminds you how little you actually need. And how strong it feels to be uncomfortable sometimes.

    I found silence in Iceland，and time to consider the me outside of career and the me outside of kids as I shared stories with strangers.

    When I stopped talking and just listened，I became more generous. I 1earned that choosing to be generous can create more space, more food and more warmth.

    But I didn't really gain any better appreciation of what I want from life or my job. I suspect the anxiety that drove me to seek silence in Iceland was losing sight of my ability to choose gratitude and joy，and to be present in the challenges I set in my career and my family.

    I came home to noise，rush and love; with no less confusion on who I want to be. I know the answer isn't waiting out there on the top of a mountain in Iceland. The answer is in front of me with every step on my own 1ife's path, and in every choice I make.
