Why Exercise Is Cool?
1. Exercise Strengthens Muscles
Did you ever do a push-up or swing across the monkey bars at the playground? 1. By using your muscles to do powerful things, you can make them stronger. For older teens and adults, this kind of workout can make muscles bigger, too.
2. 2.
Can you touch your toes easily without yelling ouch? Most kids are pretty flexible, which means that they can bend and stretch their bodies without much trouble. Being flexible is having “full range of motion,” which means you can move your arms and legs freely without feeling tightness or pain.
3. Exercise Keeps the Balance
3. Your body needs a certain amount of calories every day just to function, breathe, walk around, and do all the basic stuff. 4. If you’re not very active, your body won’t need as many calories.
Whatever your calorie need is, if you eat enough to meet that need, your body weight will stay about the same. If you eat more calories than your body needs, it may be stored as extra fat.
4. Exercise Makes You Feel Good
It feels good to have a strong, flexible body that can do all the activities you enjoy—like running, jumping, and playing with your friends. It’s also fun to be good at something, like scoring a basket, hitting a home run, or perfecting a dive.
But you may not know that exercising can actually put you in a better mood. 5. It’s just another reason why exercise is cool!
A. So you want to do some aerobic (有氧的) exercise right now?
B. Food gives your body fuel in the form of calories, which are a kind of energy.
C. When you exercise, your brain releases a chemical, which may make you feel happier.
D. Those are exercises that can build strength.
E. Exercise Makes You Flexible
F. Exercise Makes Your Heart Happy
G. But if you’re active, your body needs an extra measure of calories or energy.
Sometimes people call each other "freaked-cat", but have you ever thought about this expression? When a cat is frightened, its heart starts beating faster, its muscles get tense, and there are changes in the chemicals in its bloodstream.Although the cat doesn't realize this, its body is getting ready for action.If the danger continues, the animal will do one of two things.It will defend itself, or it will run away as fast as it can.
???? Something like this also happens to people.When we are excited, angry, scared, or aroused by other emotions (feelings), our bodies go through many physical changes.Our hearts beat faster, and our muscles get tense.All of these changes make us more alert and ready to react.We, too.get ready to defend ourselves or run.
????????????? Human beings, however, have a problem that animals never face.If we give way to our feelings and let them take over, we can get into trouble.Have you ever said something in anger —or hit somebody—and regretted it later? Have you ever shouted at a teacher, told somebody you were lonely, or said you were in love, and then wished later you had kept your mouth shut?
It isn't always clever to express your feelings freely.
???? Does this mean that it's smarter always to hide our feelings? No! If you keep feelings of anger, sadness, and bitterness hidden away or bottled up inside, your body stays tense.Physical illness can develop.It can actually be bad for your health.(It isn't good to keep pleasant feelings inside either; all feelings need to be expressed.)
???? Feelings that you keep all bottled up inside don't just go away.It's as if you bought some bananas and stuck them in a cupboard.You might not be able to see them.but before long you' d smell them.And if you opened the cupboard, chances are that you'd see little fruit flies flying all over them.They'd be rotten.
???? You can try to treat emotions as if they were bananas in the cupboard.You can hide them and you can pretend they don't exist, but they'll still be around.And at last you'll have to deal with them.just like those bananas.

When Carol was diagnosed, her cancer had 21 to her bones. We calmly talked about what to expect. I reviewed choices for 22 and printed out new research. But 23 , I cried and struggled. Only half the patients are alive two years after diagnosis.
Carol began treatment afterwards. She felt almost 24 and went right back to work. Carol hates the idea of being 25 as a “sick” person. She likes her life 26 . Last winter, Carol suddenly found 27 difficult to swallow. She slept a lot and was slow to wake in the morning. There was continuous pressure in her chest and 28 I saw her looking thoughtful. One day, she told me, “I think I 29 never leave the hospital,” she continued, “I just want to enjoy the little things--- 30 is out of the window.” We had never spoken of that before. 31 we began an African safari, a trip she had dreamed of for years.
Morning and afternoon, we went diving and rolled into the clear water 32 down like peas in honey. In the evenings, we spent time on the pier, watching the sun set. One of the young couples on the island wondered if we were sisters. We laughed. “Friends for 34 years,” I said. I could see by their 33 that they didn’t really understand that kind of time. We have been friends 34 than they have been alive.
35 dives, we talked about where to go next. I made lists 36 she slept. Our plans were now more theoretical, and the big trip to the South Pacific one day seemed a long way off. Cancer has become part of our 37 . We are well aware that our bodies are temporary gifts. Not knowing what comes next means 38 is possible. Perhaps I will be hit by a truck, or my heart will stop. Life is 39 .
We took our last dive of the trip. When we reached the deep blue water, we spread our arm out like wings and pretended to 40 .

Below is a selection from a popular science book.
If blood is red, why are veins (静脉) blue? Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it’s outside the body, when it’s sitting in a vein near the surface of the skin, it’s more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison. Which works harder, your heart or your brain? That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker(超级油轮). But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it. Why do teeth fall out, and why don’t they grow back in grown-ups? Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed(腐烂)and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they are gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off. Do old people shrink(收缩)as they age? Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They simply lose height as their spine (脊柱) becomes shorter and more curved due to disuse and the effect of gravity (重力). Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards—their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved. Why does spinning make you dizzy)? Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you’re moving while you’re not. Where do feelings and emotions come from? Mostly from an ancient part of the brain called the limbic system(边缘系统). All mammals have this brain area — from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on this planet. If exercise wears you out, how can it be good for you? Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy, it’s more that a lack of exercise leaves your body weak and easily affected by disease. |

Almost everyone is afraid of something --- snakes, heights, public speaking and so on.
It is normal and can even be helpful to experience fear sometimes. In dangerous situations, fear can keep our bodies alert (警醒的) so that we can act quickly to protect ourselves.
But for some people, fear develops into a “phobia”, which is a strong and unreasonable fear of something. For example, the majority of us feel a little scared when looking down from a tall building. But people with height phobia may have trouble breathing, feel dizzy or turn down a great job just because the company is on the 20th floor.
Phobias can prevent you from living a normal life. “People with spider phobia would stay out of their home or dormitory room for days if they thought a spider was present,” Katherina Hauner, a researcher at Northwestern University, US, told ABC news. This is why scientists have been trying to find a cure for this disease.
Since fear comes from experience --- from what we are told, what we see others experience and what happens to us --- some scientists think if they can “rewrite” these unpleasant memories, they might be able to help people overcome their phobias.
In a study by Hauner and other scientists, participants with spider phobia were asked to first touch a spider with a paintbrush. Seeing that it was not actually dangerous, they then tried touching it while wearing a glove. Finally, they could hold it with their hands.
Certain medicine has also been found to be helpful. Back in 2010, researchers at the University of Hiroshima, Japan, injected (注射) a special medicine into a fish --- who was afraid of light --- to turn off the fear center in its brain. From then on, the fish no longer feared light.
While the search for solutions to phobias is making great progress, it’s an open question whether getting rid of fear is good. Some people want to use these methods to make soldiers fight harder in wars by taking away their sense of fear. Dave Smithson of the charity Anxiety UK thinks that’s a bad idea. “It’s fear that prevents us from doing crazy things,” he says. “There’s a name for people who don’t have fear of consequences: psychopaths (精神变态者).
