Do you love holidays but hate the increase weight that follows? You are not alone.

    Holidays are happy days with pleasure and delicious foods. Many people, however, are worried about the weight that comes along with these delicious foods.

    With proper planning, though, it is possible to control your weight. The idea is to enjoy the holidays but not to eat too much. You don't have to turn away from the foods that you enjoy. The following suggestions may be of some help to you.

    Do not miss meals. Before you leave home for a feast(宴会),have a small, low-fat snack(小吃). This may help to keep you from getting too excited before delicious foods. Begin with clear soup and fruit or vegetables. A large glass of water before you eat may help you feel full. Use a small plate; a large plate will encourage you to have more than enough.

    Better not have high-fat foods. Dishes that look oily or creamy have much fat in them.

    Choose lean meat(瘦肉 ).Fill your plate with salad and green vegetables.

    If you have a sweet tooth, try mints (薄荷) and fruits. They don't have fat content as cream and chocolate. Don't let exercise take a break during the holidays. A 20-minute walk after a meal can help burn off excess(过多的) calories.

    When it comes to the Internet, people talk about the password most. Actually, it's been under fire for a long time. Research has shown that passwords are not a very good way to protect sensitive information.

    People would use some random characters, numbers and symbols. Furthermore, a unique password would be used for every site or application the user uses. Unfortunately, the longer and more complex passwords become, the more people are likely to forger them. Therefore, they use the same password for every service or application. These are all big no-noes and essentially defeat the purpose of a password.

    Google is trying to kill off passwords on Android devices by introducing the Trust API, which does what simple passwords cannot and gives developers a framework for securing their application using a number of security systems and metrics(衡量标准)on the device. A Trust Score will be generated based on a number of metrics including your device location, face scanning, fingerprints, and the things like your typing speed or the way you speak. Taken one at a time, these metrics are not secure. But taken together, these metrics will help recognize the real “you”.

    The good news is that Google has already been testing this on real world data. Google has proven the Trust API works. Next Google will run tests will some banks to see if the Trust API meets their needs before rolling out the system on Android phones later. It may take another year for apps and popular sites to start using the Trust API.

    This is a pretty exciting change. Passwords have been around for a lone time. Although the security of systems has been improved, the usability of systems hasn't been proved much. Google appears to have the best of them. Maybe that never-ending conflict between security and convenience will be able to take a break once the Trust system comes out.

    Food storing is common in members of the crow（乌鸦）family. A new study tested the birds outside this naturally occurring behaviour, which may have evolved（进化）specifically because it gives crows a survival advantage. Some crow species are known to naturally use tools to recover food. So the researchers tested whether the birds could store and recover a tool so they could get it at their food after a gap of 17 hours—something we wouldn't expect them to do naturally. But they were able to instantly select the tool out of a number of unnecessary items.

    In another experiment, the researchers taught crows to select a token （礼品券）from a number of items so that they could then exchange for food. Again, the birds then showed that they could plan for the future using this new behaviour. This is different from all of the previous studies in future planning, which have focused on naturally occurring behaviour. For example, we know that chimpanzees select, transport and save appropriate tools for future needs.

    These studies have shown that animals can plan for the future—but they left an important question open for debate. Are animals only able to plan to use abilities that have evolved to give them a specific advantage, or can they flexibly and intelligently apply planning behaviour across various actions? Most critics would say the former, as the animals were tested in naturally occurring behaviours.

    But the new research provides the first evidence that animal species can plan for the future using behaviour that doesn't typically occur in nature. This supports the view that at least some recognitive abilities in animals don't evolve just in response to specific problems. Instead, it suggests that animals can apply these behaviours flexibly across problems in a similar way to humans. We need to investigate how flexible behaviour evolved. Then we might be able to see how crows' ability to plan for the future fits in with their broader cognitive powers.

    If you're dreaming of visiting one of those picture-perfect European towns filled with old-world attractiveness and scenic beauty, here is a look at the most beautiful small towns in Europe.

    Manarola

    Manarola, Italy, is filled with rainbow-colored homes carved right into a wall of stone along the Mediterranean coast. This charming fishing town is famous for its unbelievable wine, and the paintings. There are no cars here, no traffic lights, or traffic noise. You can drive to Manarola, but you'll have to park just outside the town and then take a shuttle bus or walk in on foot.

    Garmisch-Partenkirchen

    Garmisch-Partenkirchen, Germany, is a fascinating mountain town. Once two separate towns, one Roman and the other Teutonic, the 1936 Winter Olympics forced them to combine, though the two sides still have different characters. The town dates back to 15 AD, filled with narrow, cobblestoned streets lined with historic three or four-story buildings painted with regional and religious scenes.

    Marsaxlokk

    The energetic trading port of Marsaxlokk, Malta, was built in 900 BC. Today, this pictures-like town is the main supplier of fish to the island nation that sits in the Mediterranean Sea. It has no modern buildings to ruin its appeal. With such quiet surroundings, including the traditional luzzu's (fishing boats), it's a particularly charming place to visit.

    Portmagee, Ireland

    In a country filled with beautiful towns, Portmagee, is a standout, sitting on the southwest coast of Ireland. This postcard-perfect seaside fishing town has a row of brightly colored buildings along with a rich and colorful history. At The Bridge Bar, you'll find live music many nights of the week along with fantastic food and a fine glass of beer.

    Discover Nature Schools programs

    Becoming Bears (Kindergarten-2 grade)

    By becoming baby bears children learn from their "parent" to survive the seasons. Kids will find safety in the spring and learn kinds of food bears eat during the summer, and then create a cave for winter hibernation(冬眠). After learning the skills needed to survive, students will go out of the cave as an independent black bear able to care for themselves. (1.5-2 hours)

    Whose Clues? (3-5 grade)

    Kids will discover how plants and animals use their special structures to survive. Through outdoor study of plants and animals, kids will recognize their special structures and learn how they enable species to eat, avoid their enemies and survive. Using what they have learned, kids will choose one species and tell how they survive in their living places. (3-4 hours)

    Winged Wonders (3-5 grade)

Birds add color and sound to our world and play an important ecological (生态的) role. Students will learn the basics of birds, understand the role birds play in food chains and go bird watching using field guides and telescopes. Students will do hands-on activities. Students will use tools to build bird feeders, allowing them to attract birds at home.(3-4 hours)

Exploring Your Watershed (6-8 grade)

    We all depend on clean water. Examining how our actions shape the waterways around us. Go on a hike to see first-hand some of the challenging water quality problems in a city. Students will test the water quality to determine the health of an ecosystem.

    Each program is taught for a class with at least 10 students.

    All programs include plenty of time outdoors. So please prepare proper clothing, sunscreen and insect killers for children.

    To take part in a program, please email dcprograms@mdc.mo.gov.

    The latest data from the Office for National Statistics shows that one in every 12 kids is living in homes where no one has worked for at least a year. That may be due to unemployment or issues such as sickness or disability that mean they can't work, and aren't required to. This is known as being in a "long term workless" family.

    The issues faced by children in workless families have very bad influence on their development and education, limiting their future employment prospects, and reducing their opportunities to succeed throughout their lives.

    Not only does worklessness reduce family income, it can also damage families' health and stability, and thus destroy children's development. This is because many workless families are held back by disadvantages such as debt, drug and alcohol dependency, and by homelessness. Suffering from the family problems, many children face a greater and greater possibility of repeating the poor outcomes of their parents. Government research has shown that children in workless families are almost twice as likely not to reach the expected level at all stages of their education. For example, three-quarters of children from families where no one works failed to reach the expected level at General Certificate of Secondary Education (GCSE), compared to around half of children in lower-income working families.

    So attention should be paid to children in out-of-work homes. Having working parents means a child is more likely to do better at school, to have better health, education and development, and also means they are less likely to fall into crime.

    But for some families, worklessness, or not employment, is the norm. They just choose not to work. These families often face huge barriers to getting on with their lives but they take the opportunities offered by the society. Parents' ability to work is frustrated by issues like low skills or poor mental or physical health, or drug and alcohol dependency, leaving children without the stability they need.

    We all want to help workless families with complex problems so that their children can take advantage of the opportunities in Britain. We all want parents to have the chance to go out to earn a living and to enjoy the pleasure of work, so that their children can benefit from the good examples of working parents. In doing so, we should know the need to understand the complex issues that some families face and to develop a new approach to deal with poverty. Because the root causes are not financial. It is about helping families overcome the problems they face so that they can go as far as their talents and hard work will take them. We shouldn't retreat from acting to deal with disadvantages, because we know the costs of inaction to individuals, communities and society.
