How would you like to learn more without having to study more？Here’s how：
1．Get to bed and go to sleep.Your performance，attention，and the ability to concentrate are damaged by lack of sleep.Teenagers need nine to ten hours of sleep a night for best performance.
2．Feed your head.The brain runs badly if it doesn’t get enough fuel.That means protein(蛋白质)and complex carbs (复合碳水化合物)－eggs and wheat bread for breakfast，say，rather than sugary cereal(含糖的麦片粥)and orange juice.The biggest mistake teens make is not to have breakfast or to go for sugar，which raises blood sugar levels.
3．Body exercise is brain exercise.Body exercise really improves brain performance，perhaps because it increases blood flow，or perhaps because it reduces stress and anxiety(焦虑).Twenty minutes of activity a day that raises your heart rate will do great good.
4．Learn now what you want to remember for the rest of your life.Teenage brains are much better at remembering things than the brains  of young children or adults.Scientists aren’t sure why.Whatever the reason，the teenage years are the time to learn new languages and master other lifelong skills.
5．Learn the power of risk taking.Adults are always worried about the downside of teenage risk?taking，and it’s true that teenagers are more likely than adults to get themselves in trouble by drinking and driving.But the fact that the parts of the brain that drive people to try new，risky，and exciting things appear to be more developed in teenagers can be a huge advantage.Pick certain challenges－difficult sports，a hard job，mastering a performance art，traveling overseas－and the teenage brain is able to deal with them.They have this power they’re given to go out and do it without fear.
6．Learn what you love.Because emotional(情感的)systems develop fast in teenager brains，teenagers learn things they’re interested in quickly and well.Their brains give them tools like attention on the project.
【小题1】According to the passage，teenagers should have　　　　for breakfast.

D

He looks like somebody important! I remember thinking about a middle-aged man standing at a checkout counter． Something set him apart． Even the boy bagging groceries seemed to sense it． He sped up than usual as he glanced with respect at the man．

Trying to find out what was different about him, I found that he looked quite ordinary． Although he gave the impression of being tall, I could see he was actually a little shorter than average． His appearance wasn’t particularly outstanding, and he was wearing plain weekend sports attire ( 运动休闲装 )． Not until the man was leaving did it strike me． He carried himself as if he were somebody worth caring about． Head up and chest out, he walked proudly from the market． I watched the other shoppers as they looked down over their baskets． And me? In the glass of the store’s side doors, I saw reflected ( 映现 ) a worn-out housewife who looked as if she’d carried too many bags of groceries．

Suddenly, the words I’d heard my mother repeat hundreds of times as I was growing up held new meaning． “Stand up straight ! Lift yourself by pretending strings are pulling you from the tops of your ears．” I thought of myself being pulled up ． I felt taller as I came nearer to the market’s doors． This time I saw reflected a woman who looked as if she knew where she was going! But as I rushed home in five o’clock traffic and tried to fix dinner before a seven o’clock meeting, my good manners disappeared． It wasn’t until the next day as I was trying on clothes in a department store that I remembered again． Each thing I put on seemed wrong． Suddenly I recalled the man in the supermarket． I lifted myself up． The dress looked nicer on me． I liked the dress! Sure enough, I looked five to seven pounds lighter． Dieting titles I’d read came to mind, such as “How to Lose Pounds in Weeks?” Now I had a new title: “How to Look Thinner in Seconds．”

Everyone knows that exercise is important. We all need to exercise. Doctors say it is good for us. It makes your heart and body strong. Children who often exercise are more alert (灵活). This means they do better in tests and schoolwork than those who don’t exercise.
There are many ways to exercise. You can walk, run, swim, skate, or play ball games. Make sure you exercise in the following ways; you have to like what you’re doing. Exercise enough— but not too much. It’s best to exercise twice each week, Thirty minutes each time is enough. Try all kinds of things until you find one, two or even three sports that feel right for you.
You can exercise at fitness centers. They have a lot of equipment（设备）there. The equipment will help to exercise your arms, legs and other parts of your body to make you fit. Some people buy equipment for their homes. But it is very expensive.
Exercising can be fun. Friends can exercise together at a fitness center or they can play sports together. How do you exercise?
