Paparazzi, (狗仔队)or “paps”, are photographers who take pictures of famous people when they are not at the center of public attention. Paps are different from professional photographers or journalists because they never take ordinary photos.

    The goal for paparazzi is to get pictures that no one else will get and then sell the pictures to the buyer who offers the most money — normainly a small newspaper, magazine or website.

    There is no law against paparazzi taking pictures in public places. However, there are laws that protect certain individuals. For example, child protection laws stop improper pictures of anyone under 16 from being published.

    There is also no law that stops paparazzi from following celebrities（名人） and taking their pictures either. However, if paps are secretly following them and taking pictures of their faces, they could get into trouble.

    Most paparazzi hang out on streets and hot spots for celebrities, waiting for the opportunity to take a picture of a star. Many stay on the streets until the early hours of the morning when celebrities are leaving nightclubs and looking a little worse for wear. However, some have other ways to make sure they get pictures. Many paps are in contact with “informers” who know the locations of celebrities at any given time. They then pass the information on to paparazzi. An informer could be anyone — from a restaurant waiter to a salesman.

    Most of the time, paparazzi get a bad reputation for following celebrities. But sometimes stars or their managers will contact paps themselves and tell them exactly where and when they will go. What a love-hate relationship between paparazzi and celebrities!

    Australia is a developed country and the future of its solar industry is looking bright after a record 3.5m panels (嵌板) were installed on rooftops last year, giving the equal output of a medium-sized coal-fired power station. The record 1,057 MW of capacity (生产能力) in small-scale systems installed across the country broke the previous record set in 2012, figures from the Clean Energy Regulator showed on Tuesday.

    Australia's solar power prosperity could almost double capacity in a year. The data also revealed that the average system size has also doubled since then from three to six kilowatts as average prices continued to fall. A fully installed 5KW system costs an average of $5,930 in Australia, according to the energy broker Solarchoice. net. au. Its records show that the price has roughly halved in many capital cities since 2012.

    The regulator's executive general manager, Mark Williamson, said there was increasing interest in renewals as a way to take control of electricity bills. But more importantly, he said it was also good news for reducing carbon emissions.

    “We are seeing a wide cross-section of Australians-households, community centers, schools, and small businesses-receiving rewards under the small-scale renewable energy scheme,” Williamson said. “Our data shows consumers are embracing renewable energy to take control of their electricity bills.”

    In 2017, there was a 41% increase in installing renewable energy capacity across all states and territories compared to 2016. Queensland led the way with installed capacity at 295MW, with the Australian Capital Territory taking top place for the biggest annual increase by 57%. “The data collected by the Clean Energy Regulator in 2017 reflects the industry is going from strength to strength. It looks like 2018 will be another big year for the solar industry.”

    The total of installed capacity for last year is expected to rise to 1,070MW when all the data is collected. A large coal-fired power station such as Loyd Yang A in Victoria's Latrobe Valley has a capacity of 2,200MW.

    Wolves travel shorter distances and move slower during snowfall events, according to new research by University of Alberta biologists. The effects were most pronounced at night, when wolves hunt, and behaviour returned to normal within a day. Wolf tracks across snow in northeastern Alberta.

    "Our findings suggest that there is something about actively falling snow that causes wolves to slow down," said Amanda Droghini, a former MSc student in the Department of Biological Science and lead author on the study. "We don't know the exact mechanism behind that. It's unlikely that they were staying still because they were feasting on a recent kill. Instead, active precipitation（降雪量）might affect wolves' hunting abilities. Like rain, snow clears the air column of scent molecules. So, maybe falling snow makes it harder for wolves to detect the smell of prey."

    Over the course of two winters, the researchers used remote cameras to disclose snowfall events and estimate snow depth. To study wolf movement, they collected telemetry（测距仪） data from 17 wolves to calculate travel speed and duration, as well as resting periods. It is the first study to examine how large flesh-eating animals respond to snowfall events.

    With the effects of climate change on precipitation in the north forest region uncertain, it is difficult to predict the implications for wolf populations. Studies such as these increase our understanding of how large mammals react to normal snowfall events, but the type and amount of winter precipitation will likely have an impact on animal behavior and the energetic cost of movement.

    "Winter is already challenging for many wildlife species because moving through snow requires more energy. Snow can also make it harder for animals to access food resources," said Droghini, who conducted the research under the supervision of Professor Stan Boutin, Alberta Biodiversity Conservation Chair.

    "Anything that increases those costs, such as increased rain-on-snow events, could lead to lacking in nutrition, poor body condition, and even starvation as animals are unable to make up for those additional costs. That is one of the worst-case scenarios（设想）but, in truth, we know very little about potential changes to precipitation patterns and how wildlife will respond to those changes."

    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.

Nearly everyone has spent at least one night lying in bed wishing for sleep. But for many, it's a nightly struggle. The key, or secret, is to experiment. What works for some might not work as well for others. {#blank#}1{#/blank#}

Set a regular bedtime. Go to bed at the same time every night. {#blank#}2{#/blank#} Try not to break this routine on weekends when it may be attractive to stay up late. If you want to change your bedtime, help your body adjust (调整).

{#blank#}3{#/blank#} If you're getting enough sleep, you should wake up on time naturally without an alarm.  As with your bedtime, try to keep your regular wake﹣up time even on weekends.

Be smart about napping (打盹). Though taking a nap can be a great way to become energetic again, especially for older adults, it can make insomnia (失眠)worse. {#blank#}4{#/blank#} If you must nap, do it in the early afternoon, and limit it to thirty minutes.

Fight after﹣dinner drowsiness (睡意). What should you do when getting sleepy before your bedtime？{#blank#}5{#/blank#} For example, washing the dishes, or calling a friend. If you give in to the drowsiness, you may wake up later in the night and have difficulty getting back to sleep.
