It's natural for all kids to worry at times, and because of personality differences, some may worry more than others. {#blank#}1{#/blank#} They typically worry about things like grades, tests, their changing bodies, fitting in with friends, the goal they missed at the soccer game, or whether they'll be bullied (欺负), or left out. Luckily, parents can help kids manage worry and deal with everyday problems.

    To help your kids manage what's worrying them:

    Find out what's on their minds.

    Be available and take an interest in what's happening at school, on the team, and with your kids' friends. {#blank#}2{#/blank#} As you listen to stories of the day's events, be sure to ask about what your kids think and feel about what happened. Sometimes just sharing the story with you can help lighten their load.

    {#blank#}3{#/blank#}

    Being interested in your child's concerns shows they're important to you, too, and helps kids feel supported and understood. Reassuring (令人安心的) comments can help—but usually only after you've heard your child out. Say that you understand your child's feelings and the problem.

    Guide kids to solutions.

    {#blank#}4{#/blank#} When your child tells you about a problem, offer to help come up with a solution together. If your son is worried about an upcoming math test, for example, offering to help him study will lessen his concern about it.

    Offer reassurance and comfort.

    Sometimes when kids are worried, what they need most is a parent's concern and comfort. {#blank#}5{#/blank#} It helps kids to know that, whatever happens, parents will be there with love and support.

    The researchers say a person loses two months for every kilogram overweight they are— and seven years for smoking a packet of cigarettes a day.

    Unusually, the Edinburgh university team found their answers by analysing differences in people's genetic code or DNA. Finally they think it will show new ways of helping us to live longer.

    The group used the genetic code of more than 600, 000 people who are taking part in a natural experiment. If someone smokes, drinks, drops out of school and is overweight, it can be difficult to identify the impact of one specific unhealthy behavior.

    Instead, the researchers turned to the natural experiment. Some people carry mutations(变异) in their DNA that increase(食欲) or make them more likely to put on weight, so researchers were able to compare those programmed to eat more with those who were not. The research team also found specific mutations in human DNA that alter lifespan (寿命).

    Mutations in a gene (a set of instructions in DNA) that is involved in running the immune system could add seven months of life on average.

    People with a mutation that increased levels of bad cholesterol knocked eight months off lifespan.

    A rare mutation in a gene—APOE—linked to dementia reduced lifespan by 11 months.

    And one that made smoking more appealing cut lives by five months.

    Dr Joshi says that while genes do influence lifespan, “you've got even more influence” through the choices you make. Dr Joshi said, “We hope to discover genes affecting lifespan to give us new information about ageing and construct treatment tor ageing.”

    There are also some disease mutations that clearly affect lifespan and to destructive effect, such as the Huntington's gene. People with Huntington's often die in their 20s.

    However, in order to follow people until the end of their lives, many of the people studied were born before 1940.

    More than 40 million Americans move each year, but not always by choice. Whether you're moving because of work or schooling or for better chances, adjusting to（适应）the life in a new place can be difficult. {#blank#}1{#/blank#} Here are some tips to help you adjust to your new home.

    Treat it as an adventure(冒险)

    {#blank#}2{#/blank#} So stay positive and get out there and explore! Taste the local food and visit famous places and museums. Try local activities that aren't popular in your former city, such as skating if you come from a beach town or surfing if you lived in the mountains. You may discover a talent(才华) or interest you never knew you had.

    Get involved with（介入）your neighbors

    Introduce yourself to neighbors and everyone else you meet. {#blank#}3{#/blank#} This is the best way to get advice about living in your area, and to make new friends. Attend local events that interest you, visit the markets or yard sales, take classes and so on. All of these things will help you meet people and feel connected.

    {#blank#}4{#/blank#}

    It takes time to get to know a new place, so don't expect to feel comfortable right away. {#blank#}5{#/blank#} To help make the process easier you can meet new people, find a support group near you. A fresh move is also a fresh start. Therefore it is a great time to start realizing a dream you've had, whether it is going back to school, starting a new career, or finishing a novel.

A. Find what you love.

B. Be patient and go after your dream.

C. Give yourself time to adjust.

D. Tell them you're new in the town.

E. It is especially true when you don't love your new city very much.

F. Show others the photos of your favorite places in your old town.

G. Living in a new place is a great opportunity to experience new things and grow up.

    Reading may be fundamental, but how the brain gives meaning to letters on a page has been a mystery. Two new studies fill in some details on how the brains of efficient readers handle words. One of the studies, published in the April 30 Neuron, suggests that a visual-processing area of the brain recognizes common words as whole units. Another study, published online April 27 in PLOSONE, makes it known that the brain operates two fast parallel systems for reading, linking visual recognition of words to speech.

    Maximilian Riesenhuber, a neuroscientist at Georgetown University in Washington, D. C. , wanted to know whether the brain reads words letter by letter or recognizes words as whole objects. He and his colleagues showed sets of real words or nonsense(无意义的词语)words to volunteers undergoing FMRI scans. The words differed in only one letter, such as “farm” and “form” or “soat” and “poat”, or were completely different, such as “farm” and “coat”or “poat” and “hime”.The researchers were particularly interested in what happens in the visual word form area, or VWFA, an area on the left side of the brain just behind the ear that is involved in recognizing words.

    Riesenhuber and his colleagues found that neurons(神经元)in the VWFA respond strongly to changes in real words. Changing “farm” to “form”, for example, produced as great a change in activity as changing “farm” to“coat”, the team reports in Neuron. The area responded slowly to single-letter changes in made-up words.

    The data suggests that readers grasp real words as whole objects, rather than focusing on letters or letter combinations. And as a reader's exposure to a word increases, the brain comes to recognize the shape of the word. “Meaning is passed on after recognition in the brain”, Riesenhuber says.

    The researchers don't yet know how longer and less familiar words are recognized, or if the brain can be trained to recognize nonsense words as a unit.

    “How can we live longer?” many people wonder. Being sociable looks like a good way to add years to your life. Relationships with family, friends, neighbors, even pets, will all do the trick, but the biggest longevity (长寿) boost seems to come from marriage or an equal relationship. The effect was first noted in 1858 by William Farr, who wrote in 1858 by William Farr, who wrote that widows and widowers (鳏夫) were at a much higher risk of dying than their married peers. Studies since then suggest that marriage could add as much as seven years to a man's life and two to a woman's, The effect holds for all causes of death, whether illness, accident or self-harm.

    Even though the odds are stacked against you (the conditions are not favourable to you), marriage can more than compensate. Linda Waite of the University of Chicago has found that a married older man with heart disease can expect to live nearly four years longer than an unmarried man with a healthy heart. Likewise, a married man who smokes more than a pack a day is likely to live as long as a divorced man who doesn't smoke. There's a less pleasant side, however, as partners are more likely to become ill or die in the couple of years following their spouses; death, and caring for a spouse with mental disorder can leave you with some of the same severe problems. Even so, the odds favour marriage. In a 30-year study of more than 10,000 people, Nicholas Christakis of Harvard Medical School describes how all kinds of social networks have similar effects.

    So how does it work? The effects are complex, affected by socioeconomic factor, health-service provision, emotional support and other more physiological mechanisms (机制). For example, social contact can boost development of the brain and immune system, leading to better health and less chance of depression later in life. People in supportive relationships may handle stress better. Then there are the psychological benefits of a supportive partner.

    A life partner, children and good friends are all recommended if you aim to live to 100. The best social network is still being mapped out, but Christakis says: “People are interconnected so their health is interconnected.”

    "Mummy, I don't know what to play with." Steve interrupts his mother, who is talking to a friend, for the fourth time. "You've got a room full of toys!" his mother says, impatiently. In fact it is the jumble of toys which is to blame for four-year-old Steve's lack of interest in his dolls, cars and stuffed (packed) animals. Each morning he tips out three washing baskets of toys all over his floor, listlessly pulls out something and shortly after is standing at his mother's desk or following her into the kitchen saying: "Mummy, I am bored."

    A family therapist (心理医生) explains why children lose interest when they have a whole "toy shop" at home: "According to their brain development, little children are not in a position to judge the quality of a variety of things at once. There is always just one favorite toy for the moment. All the rest is left lying about." What can parents do to stop their children from being oversupplied with toys? Under no conditions simply make something disappear without the child's knowledge. If he/she takes no more notice of a toy, a parent can ask if it can be stored or given away. Be warned though the child will always say he/she wants it then! A talk with relatives and friends may also help. Lyn is the mother of four-year-old Jessie, and we like her way. A small set of shelves in her child's room holds the toys and books that are the current (at present) favorites. When it seems to her that her daughter is tired of these toys, they put them away in a box together and select some other toys from a cupboard in another room. The box of "old" toys goes into the cupboard. When her child says she is "bored", they also get something from her cupboard - it may be something she has had for some time but because she hasn't seen it for a while it is almost like a new toy.

    Some favorite toys stay out all the time, and there is collection of dolls which sits in the corner, but in this way Lyn has found that she has fewer toys to put away at the end of the day and her daughter always has something "fresh" to play with.
