Nail-biting(咬指甲) is one of the most common annoying habits in children. {#blank#}1{#/blank#} But you needn't worry too much and as soon as you realize what's causing nail-biting, you can help your child overcome and stop it. So, here's what you can do about it.

    {#blank#}2{#/blank#}In some cases, children won't even realize they are biting their nails, let alone know why they are doing it. So make sure you have a conversation with your child (if he/she is old enough) and make him/her realize he/she is doing it and try to figure out why it's happening.{#blank#}3{#/blank#} It's important to agree on the level of your involvement. If he/she wants help, create a secret reminder that will make him/her stop without embarrassing him/her.

    Give alternatives (替代物).{#blank#}4{#/blank#} Depending on the age of the child, there are several things that you can offer such as a small ball, Play-Doh games, or any kind of other small toys.

    Use bitter solutions(溶液). Forcing a child to keep this solution on his/her fingers may feel like a punishment.{#blank#}5{#/blank#} Everything else will only lead to embarrassment and discouragement. Furthermore, some of these solutions contain pepper which burns if it enters a child's mouth or eyes. But if you have an adolescent child who wants to quit biting his/her nails, you may suggest and try out this solution.

A.It's also likely to continue as the child grows up.

B.Help the child become aware of the habit.

C.You should also consider asking for professional help.

D.Make an agreement on how you're going to stop it together.

E.The best thing children can do is communicate with their parents.

F.The child needs to go through the process painlessly and in agreement with you.

G.That will keep his/her hands occupied when he/she is likely to bite his/her nails.

    A study published Monday found that people who sleep less tend to be fat，and experts said it's time to find out if more sleep will fight fatness.

    “We've put so much emphasis on diet and exercise that we've failed to recognize the value of good sleep，”said Fred Turek，a physician at Northwestern University.

    Monday's study from Eastern Virgnia Medical School in Norfolk covered 1,000 people and found that total sleep time decreased as body mass index－a measure of weight based on height increased.

    “Men slept an average of 27 minutes less than women and overweight and fat patients slept less than patients with normal weights，”it said.In general the fatter subjects slept about 1.8 hours a week less than those with normal weights.

    “Americans experience insufficient sleep and fat bodies.Clinicians are aware of the burden of fatness on patients，”the study said.

    “Our findings suggest that major extensions of sleep time may not be necessary，as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index，”it added.

    “We caution that this study does not set up a cause­and­effect relationship between restricted sleep and fatness，but investigations indicating success in weight loss via extensions of sleep would help greatly to set up such a relationship.”

    The study was published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joseph Bass commenting on it and related research.

    In an interview，Turek said some studies have shown the lack of sleep causes declines in an appetiteholding back protein hormone，and increases in another hormone that cause a longing for food.“In addition neuropathies(神经疗法)in the brain governing sleep and fatness appear to overlap(部分重叠)，”he said.

    “Fatness has been rising dramatically in developed countries and reached epidemic(流行病)levels in the United States，”it added，“leading to a variety of health problems.”

    Aristotle once wrote that “happiness is a state of activity”. In other words, whether you're seeking life-long satisfaction or a few moments of good cheer, you've got to move forward. We've interviewed the experts and found five steps to take toward a sunny mood（心情）：

    Over a 30-year period, University of Illinois researchers asked nearly 120, 000 people how income, education, political participation volunteer activities and close relationships affected their happiness. Reported Newsweek, s Sharon Begley on the findings, “The highest levels of happiness are found with the most stable and satisfying relationships. ”

    Singing aloud, talking to a stranger, raising your hand: all may increase a feeling of happiness, according to a study from Wake Forest University. Participants（参与者）followed the development of their moods for two weeks and reported feeling happier when they were more outgoing and less happy when reserved or withdrawn.

    The editors of forbes. Com gave $5 or $20 to 46 strangers by chance. Half the group was told to spend the money on themselves, while the other half was told to spend it on others. Those who'd shared the wealth felt much happier at the end of the day than those who'd spent it on themselves. There was no difference in happiness between those who spent $5 or $20, suggesting that it's not how much money you spend, but how you spend it, that inspires the spirit.

    Studies from the Positive Psychology Center showed that discouraged people who wrote down three good things that happened to them each day for six months reported an improved attitude.

    Drinking water really can help keep you cheerful. A small 2012 study from the University of Connecticut suggested that even slight dehydration（脱水） affected the moods of its female participants.

    【1】A safari park is a park in which wild animals are kept. They are mainly located in east or central Africa. They often occupy a very wild area, with mountains and rivers. To visit the park and look at the animals, people have to drive around in a car for a few of hours because the park is huge.

    【2】In south Africa there is a safari park, which contains all sorts of wild animals like lions, elephants, rhinoceroses(犀牛), zebras, wild pigs, deer and giraffes.

    【3】There is a wild road leading through the park, but nobody is permitted to walk on the road. Anyone traveling in the park has to go in a car because wild animals may fiercely attack people. From the car he may see almost every types of African wildlife. Some of these are getting scarce (稀有的) because people kill them for various reasons. For example, rhinoceroses are killed for their horns (角), which are used in traditional Chinese medicines for colds and headaches. Perhaps they will be seen only in museums and books one day.

    【4】Travels may buy food for the animals. They can feed them when they tour the park. Of course, they should not feed them in a close distance because the wild animals may attack people. In addition, they should only give proper food to the animals.

    【5】A traveler may carry a gun with him in his journey. The gun is given to him by the government. However, it is not used for hunting. In fact, a seal(封条) is fixed to it. The traveler may fire at a wild beast to defend himself in case he is attacked. However, he has to prove to the government that he has been attacked and that he has not fired at a harmless animal.

Digitalization could Pay Off in Health and Sustainability

With technology permeating (渗透) everything we do, it has led to a significant transformation in the workplace — specifically, how, where, who is working and what work employees do. The speed of change across industries has also caused greater uncertainty as many businesses rethink the way they manage their talent and real estate.

For one, automation and artificial intelligence will change many job functions—particularly jobs and tasks that are manual or process driven. Research has found that the future workforce will be divided into three parts；core employees，freelancers（自由职业者）and consultants．Core employees will be concentrated in smaller and fewer locations, ideally in central business districts with transportation and amenities(便利设施) concentrated nearby —reducing their energy and resource usage. This smaller core workforce could mean smaller office footprints requiring less energy from power and less waste produced. In parallel, the appearance of the “liquid workforce”— freelancers, consultants and more — means potentially less commuting(通勤) and perhaps a cleaner way of working. The need for flexibility to accommodate the uncertain operating environment and more project-based work could require possibly less material and waste in the building process.

We've seen how many forward-thinking organizations have already adopted more efficient real estate management in the form of smart buildings and smart offices. This is essentially powered by the Internet of Things(物联网) to drive efficiency and real-time optimization (最优化）of building operations such as automatic monitoring and optimization of air conditioning— of particular interest in Asia, where indoor as well as outdoor air quality is a long-time issue.

    Some features of smart buildings and workplaces also announce a shift to a less paper-based workplace. Companies are also accepting a whole view of sustainability. They're thinking about more than cost-savings or making the most of space. They are considering creating a healthy, fulfilling, and productive environment for employees.

We now speak about healthy buildings instead of simply sustainable ones. In fact, the World Green Building Council now promotes the concept of healthy green buildings—buildings that are not only environmentally sensitive but also provide for the well-being of staff. For instance, buildings with more access to nature and greenery make a significant difference to workers. A survey done last year found that over 90% of those surveyed felt more productive and creative with access to fresh air, indoor light, healthy food, fitness centers and even mental health services.

    Overall, the drive towards a digitized workplace and improved employee experience could just lead us to a healthier, happier life and a more sustainable future.

    Patrick and Rachel Hugens have biked around the world. The Hugenses, who live in Boise when not on their bikes, are 25 months into their latest round-the-world adventure, scheduled to end in March. They've visited 36 countries on this tour, touching Europe, Africa, Asia and South America. “Traveling by bike is the greatest freedom," Rachel said via email. “You can see people's daily lives and can communicate with them.”

    Rachel warns, “Cycle touring can become addictive.” Bike tourism is on the rise in the United States and around the world, according to the Adventure Cycling Association. The U. S. Bicycle Route System has grown 66 percent in the past two years and now has a presence in 24 states, including Idaho, and the District of Columbia.

    Dennis Swift，secretary of the Southwest Idaho Mountain Biking Association, rode across the U.S. last year- from Seattle to Salem, Mass. Six people started the tour and three finished, riding 52 out of 56 days. They averaged about 60 miles per riding day. Swift also rode through the Basque Country with a group of Boise cyclists last year. He's planning to participate in a Virginia bike tour this year. “When you get older, your health is most important,” he said. “My mom had Alzheimer's disease. They say what's good for health is good for the brain, so riding is one thing to be first in my life.”

    This is the third time that the couple have quit their jobs to tour. Rachel is a nurse; Patrick is an architect. Both regained their former jobs when they returned home in 2000 and 2007. They're uncertain what will happen this time. They've given themselves a chance to save extra money by going to work by bike and avoiding some bills that are basic for most (cell phones, cable TV).“Traveling changes your view of money and what it can do for you,” Rachel said. “We've met some cyclists traveling long term. They have many reasons to spend wisely.”

    “The fellow cyclists we meet mostly come from Britain, Germany, Spain, Holland, Australia or New Zealand," Rachel said, “It is so nice to see that people all over the world are friendly and welcoming.”
