The Humane Society of Utah,a non-profit organization,is the largest shelter in the state because it takes every animal that can be lawfully accepted.The shelter employed photographer Guinevere Shuster,from New York,who came up with a creative way to find new homes for the dogs.She took lively photos for them.

The 31-year-old created sets of four pictures showing the playful and serious sides of each animal.Guinevere Shuster tried her best to show these dogs the way they'd really look if you allowed them into your life.She said,"I'm always trying to imagine better ways to make the poor animals attractive to the public.The photos show their great personalities and are a much better way than presenting them as the sad dogs waiting to be taken home.I'm lucky because I get to connect the two things I love most,animals and photography."

Guinevere says she finds it easy to work with dogs.She said,"It's just me and the dog in the office so they can pay their attention to the photo-taking.I use a lot of treats and some funny noises I've learned to get the dogs' attention. A fun method is to throw treats at the dogs-it's useful for getting unusual looks from them."

    Since starting the project,a number of dogs have been taken home by dog lovers after they saw Guinevere's pictures on the Humane Society of Utah's Facebook page.In the last three years,she has photographed more than 4,000 animals.This year,the shelter has placed nearly 9,000 homeless pets into their permanent homes.

    Increasingly, over the past ten years, people-especially young people have become aware of the need to change their eating habits, because much of the food they eat, particularly processed food, is not good for the health. Consequently, there has been a growing interest in natural foods: foods which do not contain chemical additives and which have not been affected by chemical fertilizers（化肥）widely used in farming today.

    Natural foods, for example, are vegetables, fruit and grain which have been grown in soil that is rich in organic matter. In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it with essential vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the amount but not the quality of foods grown in commercial farming areas.

    Natural foods also include animals which have been allowed to feed and move freely in healthy pastures（生活状况）. Compare this with what happens in the mass production of poultry（家禽）: there are battery farms, for example, where thousands of chickens live crowded together in one building and are fed on food which is little than rubbish. Chickens kept in this way are not only tasteless as food; they also produce eggs which lack important vitamins.

    There are other aspects of healthy eating which are now receiving increasing attention from experts in diet. Take, for example, the question of sugar. This is actually a nonessential food! It is not that sugar is harmful in itself. But it does seem to be additive: the quantity we use has grown steadily and in Britain today each person consumes an average of 200 pounds a year! Yet all it does is provide us with energy, in the form of calories. There are no vitamins in it, no minerals and no fibre.

    Downloading music over the Internet is pretty common among high school and college students. However, when students download and share copyrighted music without permission, they are against the law.

    A survey of young people's music ownership has found that teenagers and college students have an average of more than 800 illegally copied songs each on their digital music players. Half of those surveyed share all the music on their hard drive (硬盘), enabling others to copy hundreds of songs at any one time. Some students were found to have randomly linked their personal blogs to music sites, so as to allow free trial listening of copyrighted songs for blog visitors, or adopted some of the songs as the background music for their blogs. Such practices may be easy and free, but there are consequences.

    Sandra Dowd, a student of Central Michigan University, was fined US $7,500 for downloading 501 files from Lime Wire, a peer-to-peer file sharing program. Sandra claimed that she was unaware that her downloads were illegal until she was contacted by authorities. Similarly, Mike Lewinski paid US $4,000 to settle a lawsuit（起诉）against him for copyright violation (违反). Mike expressed shock and couldn't believe that this was happening to him. “I just wanted to save some money and I always thought the threat was just a scare tactic(战术).” “You know, everyone does it,” added Mike.

    The RIAA （Recording Industry Association of America）, the organization that files lawsuits against illegal downloaders, states that suing (控告) students was by no means their first choice. Unfortunately, without the threat of consequences, students are just not changing their behavior. Education alone is not enough to stop the extraordinary growth of the illegal downloading practice.

    As the weather gets colder, we start wearing jackets, and most of us stop thinking about the sun. But the sun's rays can be just as harmful when it's cold and cloudy outside. "Any exposed area of your body can still get sunburned," Dr. Apple Bodemer, an associate professor at the University of Wisconsin-Madison, told Live Science.

    Whether you spend a day on the slopes, skating on a pond or clearing snow out of your driveway, your face is still getting exposed to the sun's radiation in the form of ultraviolet (紫外线) (UV) light, which can go deep into your skin cells causing DNA damage, according to Bodemer.

    The sun's long ultraviolet A (UVA) waves can cause earlier aging, sunspots and wrinkles, while its short ultraviolet B (UVB) rays are known for causing skin reddening and burns.

    Skin damage caused by UV exposure increases over time. More exposure to radiation contributes to more severe damage, even skin cancer. In addition, snow and ice can also make sun damage worse. They reflect up to 80 percent of UV rays reaching the ground. That means you get hit from both the sky and the ground. And skiers and snowboarders increase their risk of getting sunburned even more because UV exposure increases at higher altitudes.

    "Generally, the biggest factor for sun-sensitivity is how pale your skin is," he said. "But, the reality is that even the darkest individual can get sun damage."

    Luckily, the solution for protecting your skin is simple: Wear sunscreen every day. Rigel recommended using sunscreen with a sun protection factor (SPF) of at least 30, and going higher at high altitudes. As a rule of thumb, SPF 30 will block 97 percent of UVB rays, SPF 50 blocking 98 percent, and SPF 100 blocking 99 percent. Whatever kind of sunscreen you use, it's important to apply SPF about once every 2 hours.

    Rigel also suggested sunscreens with "broad spectrum (光谱)"—to protect against both UVB and UVA rays—as well as sunscreens that are water resistant for up to 80 minutes. That way, you can go about your day without it wearing off too quickly.

    Do you often feel that you aren't taking in as much of the joy around you as you could? I recently caught myself feeling this way, and based on a suggestion by John Horton, coauthor (合著者) of The Inner Game of Stress, I put myself on a 30-day life-appreciation course.

    The only assignment each day was to go outside and appreciate life.

    So I started by taking in the beauty around me. During the first few days, I was able to appreciate my surroundings, although it was an intellectual appreciation, not an emotional one.

    After the first week, it was more uncomfortable to lie in bed and think about things than it was to get up and see them for myself.

    If you often wake up feeling anxious or depressed, or if you don't look forward to each day, then you need to try this course for yourself.

    It's an inner workout that you can do anywhere. It may not change your life, but it will adjust your attitude, and that's pretty helpful in this crazy world.

    I have always believed in ending the day on a positive note by writing a word or two in a gratitude journal and saying something sweet to my wife about the day we shared.

    Now, I have a new morning habit. It hasn't changed my routine one bit, but it has changed the way I look at the world.

    Creating a new habit isn't about perfection – it's about getting what you want by creating a change in your behavior and thinking.

    So now, while I'm making my coffee in the morning, I'm also appreciating what I have.

    It's quick, fulfilling, and a much better way to start my day than looking at my phone or computer.

    And because of this, my attitude is better, as I've already begun my morning on a positive note rather than a problematic one.

    The idea here is that if you can appreciate your life, it actually changes the way you feel about it.

    Appreciation will give you more energy to live the way you would like to live.

    As a means of improving our mood, it's highly underrated (被低估的). The easy task of appreciating what we have simply makes life better.

    A recent study finds that the dirt on the ground is likely to worsen climate change. Researchers have shown that warmer temperatures are heating the soil, which is causing microbes (微生物) to become more active and release more of the soil's carbon into the atmosphere. These soil changes can potentially contribute to even higher temperatures.

    Scientists studied device readings, soil measurements, plant growth details and satellite observations from around the world. Their work is the most complete study on the subject.

    They found a sharp increase in carbon released into the atmosphere by bacteria and fungi (真菌) in soil from 1990 to 2014. Researchers explain that the carbon comes from the dead plants and leaves the microbes eat. As temperatures rise, the microbes eat more. And the more they eat, the more carbon can be made into carbon dioxide and released into the atmosphere.

    This uncontrolled cycle speeds up and intensifies climate change. Overall, soil releases about nine times more carbon than human activities. But that is part of a natural cycle: the amount of carbon released into the air is about equal to the carbon oceans and plants take in.

    However, carbon released from fossil fuel causes an imbalance. Burning coal, oil and natural gas puts more carbon into the atmosphere than nature can take in. The additional carbon heats the air and soil. And as the air and soil get hotter, the earth will release more carbon than it has been holding.

    If something isn't done, we are really in trouble. Proper soil conservation can help keep more carbon in soil. Conservation methods include avoiding turning the soil, covering off-season crops and leaving crop deposits on the ground.
