The more hours young children spend in child care, the more likely they are to turn out aggressive and disobedient by the time they are in kindergarten, according to the largest study of child care and development ever conducted. Researchers said this correlation(相关性) held true regardless of whether the children came from rich or poor homes, were looked after by a relative or at a center, and whether they were girls or boys.

    What is uncertain, however, is whether the child care actually causes the problem or whether children likely to turn out aggressive happen to be those who spend more hours in child care. It also remains unclear whether reducing the amount of time in child care will reduce the risk that a child will turn into a mean person. What's more, quality child care is associated with increased skills in intellectual ability such as language and memory, leading some academics to suggest that child care turns out children who are "smart and naughty".

    The government-sponsored research, which has tracked more than 1,300 children at 10 sites across the country since 1991, is bound to cause the debate over child care again: How should people balance work and family? And how should parents, especially mothers, resolve the demands that are placed on them to be both breadwinners and supermoms?

    That debate was already on display at a new briefing yesterday, where researchers themselves had different opinions about the data and its implications（含义）. "There is a constant relationship between time in care and problem behavior, especially those involving aggression and behavior," said Jay Belsky of Birkbeck College in London, one of the lead investigators of the study who has previously annoyed women's groups because of his criticisms of child care. "On behalf of fathers or mothers?" interrupted Sarah Friedman, a developmental psychologist at the National Institute of Child Health and Human Development (NICHD) and one of the other lead scientists on the study. "On behalf of parents and families," responded Belsky.

    "NICHD is not willing to get into policy recommendations," said Friedman, contradicting her colleague. "There are other possibilities that can be entertained. Yes it is a quick solution—more hours in child care is associated with more problems. The easy solution is to cut the number of hours but that may have implications for the family that may not be beneficial for the development of the children in terms of economics." In an interview after the briefing, Friedman said that asking parents to work fewer hours and spend more time with their children usually meant a loss of family income, which adversely（不利地）affects children.

    Scientists said that the study was highly reliable. But the researchers said they had no whether the behavioral difficulties persisted as the children moved to higher grades.

    Finding out what kind and how much physical activity you need

    How do I do it?

    It's your choice. Pick an activity that's easy to fit into your life. Do at least 10 minutes of physical activity at a time. Choose aerobic activities that work for you. These make your heart beat faster and can make your heart, lungs, and blood vessels fitter. Also, do strengthening activities which make your muscles do more work than usual.

    Why should I be physically active?

    Physical activity can make you feel stronger and more alive. It is a fun way to be with your family or friends. It also helps you improve your health.

    How many times a week should I keep physically active?

    It is up to you, but it is better to spread your activity throughout the week and to be active at least 3 days a week.

    How do I build up more physical activity?

    Do a little more each time. Once you feel comfortable, do it more often. Then you can trade activities at a moderate level for vigorous ones that take more effort. You can do moderate and vigorous activities in the same week.

    Starting Cycling

    We have two services designed to give people the confidence and knowledge to cycle successfully.

    Lessons

    All our instructors have been trained to National Standards level of “Bikeability”. This means you will be trained to a standard consistent across the whole country.

    There are 3 levels of skills to progress through. Children would start with levels 1 & 2, progressing from the playground or park to cycle on less busy local roads. Teenager and adult beginners can also learn levels 1 & 2 in an off-road and quiet environment.

    Confident teenagers and adults can broaden their skills by learning level 3, using multi-lane (多道) roads and larger roundabouts (环岛). We provide both a complete package of lessons for the beginner or individual lessons tailored to the client. You can ride a bike but don't feel confident about right turns on multi-lane roads. Whatever the need we can address and practice until perfect!

    Everyone can be taught to ride a bike!

    We train both adults and children.

    We cover London Zones 1 & 2

    The cost is ￡30 per hour.

    Guided Ride

    We know that riding on the roads in London can be scary, and if you have to navigate (确定行车路线) as well it can become a real hard task! The Guided Ride service takes all the stress out of it for you by providing the following:

    Route planned in advance to suit your skill level. Route map provided to you.

    Cycle and equipment checked. We will teach you a simple method to check basic roadworthiness (车辆性能) of your bike that you can perform on a weekly basis.

    Route discussed and focus given to any areas requiring special attention.

    Cycle along with the instructor close behind. Here the traffic can be controlled by the instructor and rider observed.

    Occasionally stopping to discuss events.

    We currently cover London Zones 1 & 2. Please contact us if your requirements are outside of these areas.

    Cost ￡30

    Most of us feel very tired after working for eight hours a day, five days a week. When we get home, we watch at least one film because it's well-deserved and the only time we get to "relax" before going to sleep. Wake up and repeat. No wonder you feel tired. So how do you get out of this vicious circle? How do you restart your life?

    ⒈YOUR MINDSET

    "Oh man, another one of these self-improvement things. I hope I can do it, but I've tried these things before, and I just never stick to it."

    This was something I used to say to myself every time I try to start something new for myself. There's a fear-driven side of your brain which tells you, "You can't do this."

    What can you do? Well, the tip here is to talk to yourself like you're talking to a friend, or a coworker. So the next time you try something new, be kind to yourself like you would be kind to others. You are your own worst critic. But you can also be your firm defender.

    ⒉YOUR DIET

    If you are looking at what you eat for the reason to feel energized, then the general rules are:

    1) Eat when you're hungry. Don't eat when you're not.

    2) Be mindful when you eat. Chew at least 20 times. Let yourself taste and digest your food.

    3) Don't do three things at once when you're eating. Your body wasn't made for that.

    4) Preferably, eat "real" food. Eat what your great-grandmother would recognize as food.

    Don't let your days pass by in a boring way. Start by re-examining these key habits in your life to build a body that can start doing things you want.

    ⒊YOUR SLEEP

    Without enough sleep, we're basically going through the day drunk. This means tiredness, difficulty to respond quickly and smartly to anything that comes up. The sleeping hours needed for an average adult ranges from 7 to 9 hours.
