    US scientists say they have poured cold water on the theory that washing hands with hot water kills more germs (细菌) than unheated water. The small study of 20 people found using water at 15C (59F) left hands as clean as water heated to 38C (100F).

    National Health Service (NHS) recommends that people wash their hands in either cold or warm water. In this study, scientists at Rutgers University-New Brunswick wanted to find out if popular assumptions about the benefits of warm or hot water and official guidance on hot water —given to the food industry in the US - held true. They asked 20 people to wash their hands 20 times each with water that was 15C (59F), 26C (79F) or 38 degrees (100F). Volunteers were also asked to experiment with varying amounts of soap. Before they started the tests, their hands were covered in harmless bugs. Researchers say there was no difference in the amount of bugs removed as the temperature of the water or the amount of soap changed.

    Prof Donald Schaffner said: “People need to feel comfortable when they are washing their hands but as far as effectiveness goes, this study shows us that the temperature of the water used did not matter.”

    However, the researchers accept their study is small and say more extensive work is needed to determine the best ways to remove harmful bacteria.

    In the UK, NHS experts say people can use cold or hot water to wash their hands. They say hands should be washed for at least 20 seconds and stress the importance of using enough soap to cover the whole surface of the hands. Their guidance focuses on rubbing hands together in various .ways to make sure each surface of each hand is clean.

(1)、What does the underlined phrase “poured cold water” in Paragraph 1 probably mean?
A、Proved. B、Created. C、Contradicted. D、Accepted.
(2)、After they washed their hands with either hot or cold water,       .
A、volunteers nearly had the same amount of germ removed B、volunteers all talked about American food industry C、volunteers still had much germ on their hands D、volunteers all didn't feel very comfortable
(3)、How do researchers feel about their study?
A、It is popular. B、It is incomplete. C、It is convincing. D、It is abstract.
(4)、Which of the following is the best title for the text?
A、Using Cold Water Instead of Hot Water B、How to Use Cold Water to Wash Hands C、It Is Better to Wash Hands in Cold Water D、Washing Hands in Cold Water as Good as in Hot Water

    It may not be as easy as you think to build a foundation for your child of family values. Often we believe that our child will pick up on our values if they live in the same home. While they may pick up many of our values, parents need to remember they are not the only influence in their child's life. These outside values often compete with family values for your child's attention. If we do not make a conscious effort to instill our values into our children, they may not get instilled at all.

    I wish I had learned that lesson a little earlier. I thought if I lived my values for my children they would pick them up and make their own. Sometimes this happened and sometimes it didn't. I often see twenty-something “kids” who have no faith in many of the values of their family in favor of the values of their friends. Children will often pick up the negative you show quicker than the positive, so the positive things need extra focus to set them.

    Some of the influences your children face every day include their church, their school, their friends, any clubs or sporting groups they are part of and more. Kids spend many hours a day at school and with their friends. Sometimes in the business of life, we suppose our children will obtain that foundation we want for them.

    Instilling a foundation of family values to sustain(维持) your child requires more than living it in front of them. That is important, but building up your child with this important foundation must become intentional.

    That means we plan times to gather as a family. We plan activities together that show the values we want to pass on. We talk about our values; we live our values; we discuss the values of others and how they differ from ours; we constantly look for opportunities and make our own opportunities to share these values in word or deed with our children.

    Family values give our children a foundation to build upon. It helps them know they are loved and gives them a sense of belongings. Upon this sure foundation, they can spread their wings and grow to become parents who share these same values with their own children.

    Do you want to make a difference in your community? The Verizon App Challenge can get you started. The first step is to think of a problem in your community. The next step is to create an app that can solve the problem.

    Group of five to seven students in middle school or high school, led by a teacher, can enter the contest. First, teams will compete on a local level. Teams that make it to the next round receive $ 5,000 for their schools. Finalists present their app ideas to judges in a live web conference. Next, the judges pick national winners. The top eight teams receive an additional $ 15,000 for their schools, and each team member receives a Samsung tablet. Plus, the winning teams get the chance to bring their app to life.

    A group of six girls from Los Frenos, Texas won the second annual Verizon App Challenge. They came up with the Hello Navi app concept, short for “hello navigation”. The app was designed to help visually impaired (受损的) students navigate (导航) their school. Do you have an app idea that could help solve a local issue? The deadline to register (登记) is November 24. Find more information and register your team at verizonfoundation.org/appchallenge.

Here are some tips from the Verizon Foundation to get you started:

    Get your team together for a brainstorming meeting. Write out all the ideas that conic to mind. Don't ignore challenges. Accept the idea that you can solve a problem that exists in your community. Ask family, friends and people in your community to share their thoughts about problems that they want to see solved.

Choose the one that fits best according to the information given in the passage you have just read.

    Studies show that older people tend to remember the positive things in life rather than the negative things, while younger people remember the positive and negative equally well. The dominant psychological theory to explain this is that older people are aware of their limited time left, so they prioritize positive emotional experiences. But about a decade ago, I worked with biologist Robert Trivers on his idea that there was an evolutionary basis for older people's increased positive outlook. Our research took us in the fascinating direction of exploring how the body uses its energy.

    When our ancestors needed more energy than usual, perhaps while being chased by a tiger, they had to get that energy from somewhere in the body. Could they borrow it from the brain? That organ uses 20 percent of our metabolic (新陈代谢) output, whether we are solving math problems or watching television reruns. Due to this constant energy requirement, borrowing energy from the brain when our need surpasses the available supply is not an option. Perhaps we could borrow energy from our muscles. Because we use far more muscle energy when we are active than when at rest, in principle, we could borrow energy when we are sitting. But the problem is that most of the energy-demanding emergencies of our ancestors required a muscular response. There was no way to borrow energy from our muscles during an emergency because relaxing when a tiger showed up was not an effective response. This brings us to our immune system, which, when strong, protects us from many illnesses and diseases. Like the brain, the immune system works at great metabolic cost, but largely in the service of keeping us healthy in the future. We have an enormous number of immune cells coursing through our body, a momentary break from production is fine. So, when our body needs extra energy, one of the places it goes is our immune function. When you're being chased by a tiger, you don't need to waste energy making immune cells to fight off tomorrow's cold. What you need is to shift all available energy resources to your legs, with the hope that you will live to experience another cough or sneeze.

    As a result, our immune system evolved to run in maximum amounts when we're happy, but to slow down dramatically when we're not. With this background in mind, Trivers supposed that older people evolved a strategy of turning this relationship on its head, becoming more focused on the positive things in life in an effort to enhance their immune functioning. This was helped along by their knowing much more about the world than younger adults, so they can deal with some of the unpleasant things in life more easily.
