Youth sport has the potential to accomplish three important objectives in children's development. First, sport programs can provide youth with opportunities to be physically active, which can lead to improved physical health. Second, youth sport programs have long been considered important to youth's psychosocial development, providing opportunities to learn important life skills such as cooperation, discipline, leadership, and self-control. Third, youth sport programs are critical for the learning of motor skills; these motor skills serve as a foundation for future national sport stars and recreational adult sport participants. When coachers develop activities for youth practices and when sport organizations design youth-sport programs, they must consider the implication of deliberate play and deliberate practice.

    Research from Telama （2006） states that regular participation in deliberate play or deliberate practice activities during childhood and youth （ages nine to eighteen） increases the likelihood of participation in sports during adulthood by six times for both males and females. Côté （2002） defines deliberate play activities in sport as those designed to maximize enjoyment. These activities are regulated by flexible rules adapted from standardized sport rules and are set up by the children or by an involved adult. Children typically change rules to find a point where their game is similar to the actual sport but still allows for play at their level. For example, children may change soccer and basketball rules to suit their needs and environment （e.g. in the street. on a playing field or in someone's backyard）. When involved in deliberate play activities, children are less concerned with the outcome of their outcome of their behavior. （whether they win or lose） than with the behavior. （having fun）.

    On the other hand, Ericsson （1993） suggests that the most effective learning occurs through involvement in highly structured activities defined as deliberate practice. Deliberate practice activities require effort, produce no immediate rewards, and are motivated by the goal of improving performance rather than the goal of enjoyment. When individuals are involved in deliberate play, they experiment with different combinations of behaviors, but not necessarily in the most effective way to improve performance. In contrast, when individuals are involved in deliberate practice, they exhibit behavior. focused on improving performance by the most effective means available. For example, the backhand skills in tennis could be learned and improved over time by playing matches or by creating fun practice situations. However, players could more effectively improve their backhand performance by practicing drills that might be considered less enjoyable. Although drills are used in most effective means available practice might not be the most enjoyable, they might be the most relevant to improving performance.

    Green is not always referring to the color. In some cases, it is the term used for being environmentally friendly. If you've been looking to replace your furniture, consider going green because environmentally friendly furniture offers many benefits. Here are a few tips to get you started on your hunt for the perfect eco-friendly furniture.

    First, environmentally friendly furniture isn't harmful to your health. Also its manufacturing process doesn't cause damage to the environment in any way. Besides, by purchasing eco-friendly products, you prevent deforestation and global warming to some extent in your own way. You do your part in protecting the environment. Environmentally friendly furniture is cost-effective as well.

    The materials that are used in furniture are what make them green. Materials can be good for the environment either because they are materials that are considered renewable resources or they are all natural. A lack of chemicals and toxins (毒素) in green furniture also means it is a better choice for the environment. It may be hard to imagine that a sofa or a table could actually be a green product but they really can be depending on what they're made of.

There are a lot of renewable sources that manufacturers could use when building the furniture, so you should be keeping an eye out for them. Bamboo can be an excellent replacement for wood and can also replace plastics and metals in some furnishing. Cotton is a sofa fabric that is safe for the environment and it can be replenished (补充) often. Hemp is also a renewable source that can be used for fabric and twine.

    Recycled materials also can be made into green furniture. Metals can be recovered and remade into new things such as frames and foundations for sofas. Recycled plastic can also be made into furniture such as tables and chairs. Touching up old furniture instead of buying new items is very cheap way to be green. Yard sales and second-hand stores sell furniture too and buying the used means new things won't be made, so no more damage has to happen to the earth.

    Therefore, when you want to hunt for the perfect environmentally friendly furniture, you should try to know the type of materials which are used in building the furniture.

    It's considered to be the most important meal of the day, but do you really take the time to put together a healthy meal first thing in the morning? If you're watching your weight, skipping breakfast will damage your efforts to lose weight{#blank#}1{#/blank#} It can also speed up your metabolism (新陈代谢).

    Making breakfast a habit may not be easy. Use these tips to make eating breakfast a habit:

    Get up earlier{#blank#}2{#/blank#} Get up ten to fifteen minutes before your regular wake-up time that you have enough time to prepare a tasty meal before your day begins. Try to make time to include breakfast in your daily schedule and stick to it so it becomes a habit.

    Plan your meals ahead of time{#blank#}3{#/blank#} Put together three or four different breakfast recipes that you know you will actually eat. A little planning can help you make eating breakfast a habit as soon as possible.

    Be selective. Buy a handful of ingredients to put together a healthy breakfast yourself, instead of relying on prepared breakfast food and snacks{#blank#}4{#/blank#} If you don't like “traditional” breakfast foods, eat what you like so that you're willing to stick with it to make eating breakfast a habit.

    {#blank#}5{#/blank#} If you're working out in the morning, plan to eat breakfast within an hour after your workout so your body can recover. Again, planning ahead will make eating this meal a part of your daily routine.

A. The fresher the food, the better.

B. Breakfast is the first meal of the day.

    Six Things You should Never Do Before the Queen

    ※Don't show up empty handed.

    What do you get the woman who already has everything? Sure, the Queen has several homes full of priceless trinkets（饰品）, but bringing a gift is necessary. {#blank#}1{#/blank#} So if she's paying a visit to your hometown or country, something which reflects local culture might go down better than W.H. smith's vouchers（优惠券）.

    ※{#blank#}2{#/blank#}

You may be dead on your painful feet—but you should always stand when the queen enters the room. You may only sit once she has taken the seat, so keep a close eye on when the Queen sits down herself.

    ※Don't ignore the dress code.

    Regardless of how late you're running or how tempting it is to stay in your casual clothes, make sure you dress accordingly when meeting HRH. {#blank#}3{#/blank#}

    ※Resist the temptation to refer to her by her first name.

    While the Royal family may be extremely familiar to us, and while we may have our own nicknames for them, we common folk still aren't on a first name basis with them. So, when you meet the Queen she should be addressed as “Your Majesty” and “Ma'am” consequently after. When she leaves, however, you must address her as “Your Majesty” once again.

    ※Only speak if the queen speaks to you.

    Remember when you were a small child and all your elders would drop wisdom such as “don't speak unless spoken to first” and “children should be seen and not heard”? {#blank#}4{#/blank#} This rule exists so Her Royal Highness can control every aspect of the conversation-- including exiting it swiftly.

    ※Don't eat before she does.

    No matter how tasty and tempting the banquet morsels spread in front of you look, you can only start eating once the Queen does. So perhaps have a quick snack beforehand, in case any speeches go on for a long time. {#blank#}5{#/blank#}

A. Stand to attention.

B. Watch out for Queen.

C. Oh, and if she has finished eating, you'd better be full too.

D. If the event is black tie, wear black tie.

E. You are supposed to listen to them though you've grown up.

F. This gift must also be appropriate to the occasion.

G. The same applies to meeting the Queen.

Is it better for our bodies to work out at certain times of the day? Scientists have known for some time that every tissue in our bodies contains a kind of biological clock that goes off in response to messages related to our daily exposure to light, food and sleep.

However, whether and how exercise timing might influence metabolic (新陈代谢的) health has been less clear, and the results of past experiments have not always agreed. A much-discussed 2019 study found that men with Type 2 diabetes (糖尿病) who completed a few minutes of high-intensity interval (间隔) sessions in the afternoon improved their blood-sugar control after two weeks. Patrick Schrauwen, a professor of nutrition and movement sciences read that 2019 study with interest. He had been studying exercise in people with Type 2 diabetes, but had not considered the possible role of timing. Now, seeing the varying impacts of the intense workouts, he wondered if the timing of workouts might similarly affect how the workouts changed people's metabolisms.

Incidentally, he and his colleagues had a ready-made source of data in their own prior experiment. Several years earlier, they had asked adult men at high risk for Type 2 diabetes to ride stationary bicycles at the lab three times a week for 12 weeks, while the researchers tracked their metabolic health. They also had noted when the riders showed up for their workouts. The researchers pulled data for the 12 men who consistently had worked out between 8 and 10 a.m. and compared them with another 20 who always exercised between 3 and 6 p.m. They found that the benefits of afternoon workouts far outweighed those of morning exercise.

He says, "This study does suggest that afternoon exercise may be more beneficial for people with disturbed metabolisms than the same exercise done earlier. The particular and most effective exercise for each of us will line up with our daily routines and exercise tendencies because exercise is good for us at any time of day—but only if we choose to keep doing it."
