When I was little, Friday’s night was our family game night. After supper, we would play card games of all sort in the sitting room. As the kid, I loved to watch cartoons, but no matter how many times I asked to watching them, my parents would not to let me. They would say to us that playing card games would help my brain. Still I unwilling to play the games for them sometimes. I didn’t realize how right my parents are until I entered high school. The games my parents taught me where I was a child turned out to be very useful later in my life.

Your productivity is improved. Exercising makes you more awake and ready to handle whatever is ahead of you for the day. 2.
Your metabolism(新陈代谢) gets a head start. 3. If you work out in the mornings, then you will be getting the calorie(卡路里) burning benefits for the whole day, not in your sleep.
4. Studies found that people who woke up early for exercise slept better than those who exercised in the evening. Exercise energizes you, so it is more difficult to relax and have a peaceful sleep when you are very excited.
5. If you work out bright and early in the morning, you will be more likely to stick to healthy food choices throughout the day. Who would want to ruin their good workout by eating junk food? You will want to continue to focus on positive choices.
There are a lot of benefits to working out, especially in the mornings. Set your alarm clock an hour early and push yourself to work out! You will feel energized all day long.

According to a new study， teens focus on rewards and have a hard time learning to avoid punishment or consider the consequences of alternative actions.
University College London researchers compared how teens and adults learn to make choices based on the available information. They tracked the way in which 18 volunteers aged 12-17 and 20 volunteers aged 18-32 completed tasks in which they had to choose between abstract symbols.
Each symbol was consistently associated with a fixed chance of a reward, punishment, or no outcome. As the trial progressed ， participants learned which symbols were likely to lead to each outcome and adjusted their choices accordingly. Teens and adults were equally good at learning to choose symbols associated with reward， but teens were less good at avoiding symbols associated with punishment. Adults also performed significantly better when they were told what would have happened if they had chosen the other symbol after each choice， while teens did not appear to take this information into account.
“From this experimental lab study we can draw conclusions about learning during the teen years. We find that teens and adults learn in different ways， something that might be relevant to education," said lead author Dr. Stefano Palminteri. " Unlike adults, teens are not so good at learning to adjust their choices to avoid punishment. This suggests that incentive systems based on reward rather than punishment may be more effective for this age group. Additionally, we found that teens did not learn from being shown what would have happened if they made alternative choices."
To interpret the results, the researchers developed computational models of learning and ran simulations （模拟）applying them to the results of the study. The first was a simple model, one that learned from rewards, and the second model added to this by also learning from the option that was not chosen. The third model was the most complete and took the full context into account, with equal weight given to punishment avoidance and reward seeking. For example, obtaining no outcome rather than losing a point is weighted equally to gaining a point rather than having no outcome.
Comparing the experimental data to the models, the team found that teens" behavior followed the simple reward-based model while adults" behavior matched the complete, contextual model. “Our study suggests that teens are more receptive to rewards than they are to punishments of equal value, ” said senior author Dr. Sarah-Jayne Blakemore. “As a result, it may be useful for parents and teachers to frame things in more positive terms.”
