Exercise for a Better Brain

Most of the time, your brain is the boss of your muscle—directing how you hit a ball, play the piano, or open a cereal box.    1    When you're active, they send chemical signals telling your brain, "Hey, it's time to grow!" Recent research suggests physical activity is good for your brain and encourages the birth and growth of new brain cells.

In a study, people who ran for 45 minutes three days a week boosted their levels of a brain-derived neurotrophic(神经营养的)factor, a chemical that acts like fertilizer for new brain cells.    2    

Studies suggest that in younger adults, exercise can add to the overall number of cell in the hippocampus(海马体).    3    It's a good deal because these new brain cells are very active and get involved in more memory circuits than older cells do. At any age, you might notice that you have an easier time remembering things after you start a new exercise.

    4    If you're inactive, walking around the block may be the only way to encourage neuroplasticity. People who don't like to move but tried to walk daily by 7500 steps or more had bigger brains than those who didn't exercise—the same to 1.4 to 2.2 fewer years of brain aging. So it is advisable for people at any age to get involved in light activity, such as doing housework, shopping, gardening, or walking the dog.    5    

A.Again, a little goes a long way.
B.Tips have been offered as to how to properly exercise.
C.After four months of workouts, their scores improves on a memory test.
D.Besides this, studies have also suggested that dying cells can be cleared with regular exercise.
E.But when it comes to growing new brain cells, more and more researches show that when you exercise, your muscles take charge.
F.Exercise also helps keep brain cells alive longer and replaces old cells with new ones.
G.The more light activity study participants logged, the greater the overall size of their brains.

文章大意:本文是一篇说明文。文章主要讲述了跳舞不仅仅是一项有氧运动,对你的身体健康有好处,它也有助于你的大脑。

【推荐2】Whether you prefer solo dancing or being involved in a more formalized program, dancing offers the obvious plus to your physical health. You're not only moving your body in a rhythmic way and expressing feelings but also burning calories in your body and getting a workout for sure.

In a recent study, researchers compared the effects of walking, stretching and dancing on the wiring and gray matter of the aging brain. The result showed dancing had the significantly positive effect.

In the experiment, after volunteers in their 60s and 70s with healthy brains didn't show signs of cognitive (认知的) disorder, researchers placed them in three groups at will. One group walked, another group stretched and did balance training and the last group learned country dancing. The arrangements of the dancing became progressively more challenging over time. They all did the assigned activity for one hour a day, three times a week. After a period of six months, the volunteers' brains were re-scanned and compared to their brains when they had begun their voluntary work.

Agnieszka Burzynska, the study's lead author who is currently a neuroscientist and director of the BRAiN Lab at Colorado State University, found only one group showed a memory improvement — the country dancers. The participants who learned country dancing now had richer white matter in the part of the brain that processed memory. White matter usually breaks down as a person ages, which may lead to cognitive decline. Dancing, therefore, protected the brain from aging-caused neurodegeneration. So, dancing is not just an aerobic activity good for your physical health. It helps your brain, too!

Country dancing, ballroom dancing, tango and waltz are all done with others. When you take part in these dances, you're involved in a beneficial social activity as well. You are also cognitively motivating your brain as you learn the steps of the dances. Dancing therefore might be one of the best physical activities you can choose for brain health.

1. What's the purpose of paragraph 1?
A.To add background material.B.To introduce the topic of the text.
C.To raise questions about exercise.D.To present experimental conditions.
2. What can we learn about the volunteers in the experiment?
A.They were grouped at random.B.They were under cognitive decline.
C.They were all asked to learn dancing.D.They were all born in the 1960s and 1970s.
3. What did the researchers mainly intend to prove through the experiment?
A.The brain function of volunteers.B.The cognitive disorder of volunteers.
C.The relationship between age and dancing.D.The effect of dancing on the volunteers' brains.
4. Which of the following is the best title for the text?
A.How Dancing Affects People's Lifestyle
B.Why Dancing Is the Best Social Activity
C.How Dancing Helps People's Brain Health

【推荐3】Most young people enjoy some forms of physical activity. It may be walking, cycling, or swimming, or in winter, skating or skiing. It may be a game of some forms—football, basketball, hockey, golf or tennis. It may be mountaineering.

Those who have a passion of climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risks in high mountains? This astonishment is caused, probably, by the difference between mountaineering and other forms of activity to which men give their leisure.

Mountaineering is a sport and not a game. There are no man-made rules, as there are for such games as golf and football. There are, of course, rules of different kinds which would be dangerous to ignore, but it is this freedom from man-made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.

If we compare mountaineering with other more familiar sports we might think that one big difference is that mountaineering is not a “team game”. We should be mistaken in this. There are, it is true, no “matches” between “teams” of climbers, but when climbers are on a rock face linked by a rope on which their lives may depend, there is obviously teamwork.

The mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. His sport requires high mental and physical qualities.

A mountain climber continues to improve his skills year by year. A skier is probably past his best by the age of thirty. But it is not unusual for men of fifty or sixty to climb the highest mountains in the Alps. They may take more time than younger men, but they perhaps climb with more skills and less waste of effort, and they certainly experience equal enjoyment.

1. What sports are popular among people in winter in the passage?
A.Soccer and golf.B.Skiing and skating.
C.Cycling and hockey.D.Mountaineering.
2. What does the underlined word “passion” in Paragraph 2 mean?
A.Strong emotion.B.Good way.C.Better skill.D.Good reason.
3. Why does the author think mountaineering is a sport, not a game?
A.Because it has man-made rules.
B.Because it is too dangerous for climbers.
C.Because it can't bring people joy or leisure.
D.Because it is free for climbers to use their own methods.
4. What can we learn from the passage?
A.Mountaineering is not attractive to people.
B.Physical quality is more important than mental one for climbers.
C.A mountain climber passes his best by the age of thirty.
D.It is possible for an old man of fifty or sixty to climb the Alps.
5. What is the best title for the passage?
A.Sports in winterB.Team work in climbing
C.MountaineeringD.A mountain climber
