Finding summer jobs for teenagers has not always been easy, but now you no longer have to worry about what your kids can do to earn their own money. Recently I found some different sites online that offer information about what kids can do. Below issome of that information, along with questions to think about to help you come upwith your own ideas.

Ideas for summer work:

●Parks and Recreation Programs.

●Babysitting (当临时保姆) during the day of school.

●Working part-time at a day care for the summer.

●Car washing.

●Working at local vegetable stands.

    The easiest way for you to find ways for your child to make money is to think about others' inconveniences (不方便). Think of things you need done, or would like to have done, and what you would consider paying for these things to get done. Once you have some ideas, you can sit down with your children and talk to them aboutwhat they would be interested in doing. Then once you have an idea of what theywant to do you can help them come up with fair prices.

    Preferably you would want to only have your child working with people you know and trust, or in the least bit you could have your child pick a partner. That way with each of them carrying cell phones, even those without service can call 911, they will be much safer.

    Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experience? Strangely enough, the answer to these questions is yes. To some degree our intelligence is given to us at birth, and no amount of education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of person's intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.

    It is easy to show that intelligence is to some degree something we are born with. The closer the blood relationship between two people, the closer they are likely to be intelligent. Thus if we take two unrelated people at random from population, it is likely that their degree of intelligence will be completely different. If, on the other hand, we take two identical twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth. Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degree of intelligence.

    A lifetime of active exercise will let you keep the body of a 20-year-old well into your 70s, scientists have found.

    The physical decline (衰退) thought to be an unavoidable part of ageing is actually the result of not exercising enough, according to the research, which found that regular cyclists kept the muscles, lungs, and even the immune system (免疫系统) of people years younger. Besides, many serious health problems could be prevented if people became more active, researchers insist.

    Janet Lord, a leading researcher, said, “Our findings prove the false belief that ageing automatically makes us weaker. We now have strong evidence that encouraging people to do regular exercise throughout their lives can solve the problem that we are living longer but not healthier.”

    She looked at 125 cyclists aged 55 to 79 who had been exercising regularly for 25 years and compared them with 75 ordinary people of a similar age and 55 people aged 20 to 36. On a series of physical measures, the cyclists showed no difference from people much younger in their immune systems and making T cells.

    Now Professor Lord aims to discover how much exercise people need to do to stay young. “You needn't work out a lot. It may be intensity (强度) that helps—like going up and down the stairs ten times a day.”

    While there is no magic method of staying mentally and physically fit in later life, the benefits of keeping active can never be ignored, whatever your age or state of health.

    My six-year-old son, Stephen, was in front of the TV and smiled. His favorite show was about to begin-a Phoenix Suns basketball game.

    "Ladies and gentlemen," the announcer's voice was heard, "here is your starting lineup (首发阵容)." The arena (球场) darkened and the lights flashed when the players ran into the court to sing their team song. Stephen clapped and danced around. My wife Lorrie and I laughed. Stephen had been performing this for months. "One day I'm going to take you to a game, son," I promised.

    About a year later, the construction company where I worked finished a project for a Suns player. One afternoon my boss called me. "The player has two extra tickets for tonight's game! Just pick them up at my office," he said. I picked up the tickets, but felt a little disappointed when I looked at the clock. Even if I had had a helicopter, we would never have gone to the arena in time for the player introductions. Stephen would miss his favorite part! I grabbed my key, got Stephen in my car and hit the road. "Lord," I prayed, "I'd love to see the joy on Stephen's face. Help us make it on time."

    When I drove, it began to rain heavily. Suddenly, lightning flashed right near the arena! I turned on the radio to listen to the game. The announcer said there'd been a power failure at America West Arena. Everyone was fine, but there would be a delay until they got everything running. Finally, I parked the car and we walked in hurriedly to take our seats. I hoped that we hadn't missed the introductions.

    The very moment we entered the arena, the lights darkened. The music started. "Ladies and gentlemen, here's your starting lineup!" Stephen's eyes grew wide. There wasn't enough space for him to dance around, but I could tell that his heart was leaping more than his body was able to. Thank heaven, he hadn't missed a thing. And neither had I.

    Scientists at the University of Oxford have developed new artificial intelligence(AI) software to recognize and follow up the faces of chimpanzees(黑猩猩)in the wild. The new software will allow researchers and wildlife conservationists to significantly cut back on time spent analyzing videos, according to the new paper published in Science Advances.

    For species(物种)like chimpanzees which have complex social lives and live for many years, getting photos of their behavior taken from short-term field research can only tell us so much," says Dan Schofield, researcher and DPhil student at Oxford University's Private Models Lab, School of Anthropology. "By taking advantage of the power of machine learning to unlock large video files, it makes it possible to measure behavior over the long term."

    The computer model was trained using over 10 million images(影像):from Kyoto University s Primate Research Institute(PRI) video files of wild chimpanzees in Guinea, West Africa. The new software is the first to continuously track and recognize individual a wide range of poses, performing with high accuracy in difficult conditions such as low lighting and poor image quality.

    "Access to this large video file has allowed us to use deep neural networks to train models to a degree that was previously not possible," says Arsha Nagrad, co-auther of the study and DPhil student at the Department of Engineer Science, University of Oxford." Additionally, our new software differs from previous primate face recognition software in that it can be applied to videos with limited manual intervention(人工干预), saving hours of time."

    The technology can be potentially used to monitor species for conservation Although the present application focuses on chimpanzees, the AI software provided will be applied to other species, and help drive the adoption of AI systems to solve(解决)a range of problems in the wildlife sciences.

A researching team analyzed data from long-running studies conducted in Brazil and South Africa to assess whether children exposed to early adversities (逆境), such as extreme poverty, low birth weight, and pre-term birth, could reach their full learning potential by experiencing responsive caregiving and opportunities to learn in their home. They found that early life adversities matter throughout life. Teenagers who had been exposed to multiple adversities early in life had lower IQ scores, were more likely to have difficulties adjusting socially and psychologically, and achieved a lower physical height compared to teenagers exposed to fewer adversities. They also found that being raised in a nurturing (培育) environment could significantly counteract the negative effect of early adversities on IQ and help children achieve their full potential of intelligence.

Globally, more than 250 million children younger than 5 years are at risk of not reaching their developmental potential because of adversities that co-occur early in life and worsen with age. In the US, almost one in five children are raised in poverty and 15 percent do not complete high school. Exposing these children to a nurturing environment, whether at home or in daycare or pre-school settings, can lead to cognitive (认知的) benefits that last into teenage and beyond.

Parents should provide nurturing environments, which include interacting with young children in a positive way such as reading children's books from the library, singing songs together, and playing games with numbers and letters. Children who join in age-matched housework like picking up toys and clearing the table gain skills and feel good about helping. Get children involved in friendly activities as much as possible rather than park them in front of a screen. Children love to learn and in a nurturing environment, they can grow into teenagers and adults with the abilities to care for themselves, their families, and their communities.
