Sports medicine experts have observed for years that athletes such as long distance runners, especially women athletes, often display a lack of iron. Now a new study by a team of Purdue University researchers suggests that even moderate exercise may lead to reduced iron in the blood of women.
"We found that women who were normally inactive and then started a program of moderate exercise of middle degree showed sings of iron loss," says Roseanne M. Lyle, associate professor at Purdue. Her study of 62 formerly inactive women who began exercising three times a week for six months was published in the journal Medicine & Science in Sports & Exercise.
Iron deficiency is very common among women in general, affecting one in four female teenagers and one in five women aged 18 to 45, respectively. But the ratio is even greater among active women, affecting up to 80 percent of female endurance athletes. This means, Lyle says, that "too many women ignore the amount of iron they take in". Women of child-bearing age are at greatest risk, since their monthly bleeding is a major source of iron loss. Plus, many health-conscious women increase their risk by rejecting red meat, which contains the most easily absorbed form of iron. And because women often restrict their diet in an effort to control weight, they may not consume enough iron-rich food, and are liable to experience a deficiency.
Exercise can result in iron loss through a variety of mechanisms. Some iron is lost in sweat, and, for unknown reasons, intense endurance exercise is sometimes associated with bleeding of the digestive system. Athletes in high-impact sports such as running may also lose iron through a phenomenon where small blood vessels in the feet leak blood.
There are three stages of iron deficiency. The first and most common is having low iron reserves, a condition that typically has no symptoms. Fatigue and poor performance may begin to appear in the second stage of deficiency, when not enough iron is present to form the molecules(分子) of blood protein that transport oxygen to the working muscles. In the third and final stage, people often feel weak, tired, and out of breath - and exercise performance is severely compromised.
"People think that if they're not at the third stage, nothing is wrong, but that's not true," says John L. Beard, who helped design the Purdue study. "You're not stage 3 until your iron reserves go to zero, and if you wait until that point, you're in trouble."
Beard and other experts say it’s advisable for people to have a yearly blood test. If iron levels are low, talk with a physician to see if the deficiency should be corrected by changing your diet and taking iron-rich foods or by taking iron-added pills.
“Select breads and cereals with the words ‘iron-added’ on the label,” writes sports diet expert Nancy Clark. “This added iron supplements the small amount that naturally occurs in grains.” Clark also recommends cooking in iron pans, as food can obtain iron from the pan during the cooking process.

Hans was an honest fellow with a funny round good-humored face. Living alone, every day he worked in his garden. In all the countryside there was no garden so lovely as his. All sorts of flowers grew there, blooming in their proper order as the months went by, one flower taking another flower’s place, so that there were always beautiful things to see, and pleasant odors to smell.
Hans had many friends, the most devoted being the Miller. So devoted was the rich Miller to Hans that he’d never go by his garden without plucking a large bunch of flowers or a handful of sweet herbs, or filling his pockets with fruits. The Miller used to talk about noble ideas, and Hans nodded and smiled, feeling proud of having such a friend.
The neighbors thought it strange that the rich Miller never gave Hans anything in return, though he had hundreds of sacks of flour, many cows and sheep, but Hans never troubled his head about these, and nothing gave him greater pleasure than to listen to all the wonderful things about the unselfishness of true friendship.
In spring, summer, and autumn Hans was very happy, but when winter came, and he had no fruit or flowers to sell, he suffered from cold and hunger. Though extremely lonely, the Miller never came to see him then.
“There’s no good in going to see Hans while the snow lasts.” The Miller said to his wife, “When people are in trouble they shouldn’t be bothered. So I’ll wait till the spring comes when he’s happy to give me flowers.”
“You’re certainly very thoughtful,” answered his wife, “It’s quite a treat to hear you talk about friendship.”
“Couldn’t we ask Hans up here?” said their son. “I’ll give him half my meal, and show him my white rabbits.”
“How silly you are!” cried the Miller. “I really don’t know what’s the use of sending you to school. If Hans came up here, and saw our warm fire, our good supper, and our red wine, he might get envious, and envy is a most terrible thing, and would spoil anybody’s nature. I am his best friend, and I’ll always watch over him, and see that he’s not led into any temptation. Besides, if Hans came here, he might ask me for some flour. Flour is one thing, and friendship is another, and they shouldn’t be confused. The words are spelt differently, and mean quite different things. Everybody can see that.” He looked seriously at his son, who felt so ashamed that he hung his head down, and grew quite scared, and began to cry into his tea.
Spring coming, the Miller went down to see Hans. Again he talked about friendship. “Hans, friendship never forgets. I’m afraid you don’t understand the poetry of life. See, how lovely your roses are!”
Hans said he wanted to sell them in the market to buy back his things which were sold during the hard time of the winter.
“I’ll give you many good things. I think being generous is the base of friendship.” said the Miller. “And now, as I’ll give you many good things, I’m sure you’d like to give me some flowers in return. Here’s the basket, and fill it quite full.”
Poor Hans was afraid to say anything. He ran and plucked all his pretty roses, and filled the Miller’s basket, imagining the many good things promised by the Miller.
The next day he heard the Miller calling: “Hans, would you mind carrying this sack of flour for me to market?”
“I’m sorry, but I am really very busy today.”
“Well,” said the Miller, “considering that I’m going to give you my things, it’s rather unfriendly of you to refuse. Upon my word, you mustn’t mind my speaking quite plainly to you.”
Poor Hans was driven by his friendship theory to work hard for his best friend, leaving his garden dry and wasted.
One evening Hans was sitting by fire when the Miller came.
“Hans,” cried the Miller, “My little boy has fallen off a ladder and hurt himself, and I’m going for the Doctor. But he lives so far away, and it’s such a bad windy night. It has just occurred to me that you can go instead of me. You know I’m going to give you my good things, so you should do something for me in return.”
“Certainly,” cried Hans. He struggled into the stormy night, and got the doctor to ride a horse to the Miller’s house in time to save the boy. However, Hans got lost in the darkness, and wandered off into a deep pool, drowned.
At Hans’ funeral, the Miller said, “I was his best friend. I should walk at the head of the procession.” Every now and then he wiped his eyes with a handkerchief.

Tui Na and Your Emotional Health
In Traditional Chinese Medicine the body, mind and spirit cannot be divided and so the unique whole-body treatment in Tui Na can also be a useful treatment correcting any imbalances in the body's energy before symptoms and disease can develop. It also works to restore emotional harmony as well as physical health. This is why after a Tui Na treatment many people "feel good". Many people in China use Tui Na regularly to keep healthy and to deal with some specific illnesses.
Tui Na is performed on the clothed body and the patient is either lying on a couch or sitting on a chair. Therapists using a variety of strokes or movements will control the intensity and direction of pressure in an exact way. The unique rolling movement in Tui Na is one of the most difficult strokes to learn and students have to practice sometimes for many months on a rice bag before they are allowed to practice on the human body.
Stress
Tui Na is of course very useful for treating stress.
It distributes the energy around the whole body. It is believed that Tui Na moves the strong energy in the tense muscles to the weaker areas, thus making a more balanced body. When your Qi （energy in the body） flow is balanced you feel relaxed and comfortable. Tui Na is especially useful for stiff shoulders and tense neck muscles.
Emotions
In Traditional Chinese Medicine each major organ is linked to an emotion. By balancing the energy in the organ, the relevant emotion will be calmed. When your emotions are out of control, you would usually turn to your doctor or perhaps a psychotherapist. But perhaps some people would not like to be seeing a psychotherapist or feel nervous about discussing their problems with others. With Tui Na one does not need to tell the therapist anything one does not want to. The treatment of Tui Na can deal with the problem itself — although if one does need to talk, then the safe space is there to do so. An active dialogue between the therapist and the patient will help to get a better effect.
How the major organs rule your emotions
Each major organ — the heart, the stomach, the spleen, the liver, the bladder, the kidneys, the lungs, etc. — is linked to a relevant emotion.
The heart is linked to joy, excitement and sadness. If the heart is out of balance, the patient may dream a lot at night and often forget something important in the day.
The stomach and spleen are connected with too much thinking or worrying — over anxiety. When the stomach is out of balance there is often a lack of energy. The patient often feels very tired and has no interest in doing anything at all.
The liver and gall bladder are linked to anger. In Chinese Medicine the eyes are connected with the liver, and many people who suffer from anger often suffer from eye problems. The gall bladder rules decision-making and too much energy here can lead to rashness, while if there is too little it can bring about indecision. Where there is a history of depression, the therapist would look to the liver.
The bladder and kidneys are linked to fear of all kinds, from simple anxieties and phobias to vague fears and worries.
The lungs are connected with feelings of grief and sadness. When there is a history of grief, the therapist would look to the lungs.
Tui Na is used in almost all the hospitals in China and very popular among Chinese people. It is a useful and valuable method of restoring Qi balance, when emotional and physical health is out of balance. Tui Na is one of the remaining secrets of Chinese Medicine.

D. Tui Na only makes people "feel good" but do not actually cure disease.
2. How can the emotion be calmed?
A. By linking the organ to an emotion.
B. By telling the therapist anything one does not want to.
C. By discussing their problems with others.
D. By balancing the energy in the relevant organ.
3. When the stomach is out of balance, .
A. the patient will have a stomachache
B. the patient will have a lot to worry about
C. the patient will have nothing to do
D. the patient will not feel like doing anything
The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruits and green vegetables. It is only when people try to live on a very restricted diet, say that when trying to lose weight, that it is necessary to make special provisions to supply the missing vitamins.
An example of the dangers of a restricted diet may be seen in the disease known as "beri-beri", which used to make large numbers of Eastern people who lived mainly on rice suffer. In the early years of last century, a Dutch scientist named Eijkman was trying to discover the cause of beri-beri. At first he thought it was transmitted by a germ (病菌) . He was working in a Japanese hospital, where the patients were fed on polished rice which had had the outer coverings removed from the grain, it was thought this would be easier for weak and sick people to digest.
Eijkman thought his germ theory was proved when he noticed the chickens in the hospital yard, which were fed on remains from the patients' plates, were also showing signs of the disease. He then tried to separate the germ, which he thought was causing the disease, but his experiments were interrupted by a hospital official, who ordered that the rice without coverings, even though left over by the patients, was too good for chickens. It should be recooked for the patients, and the chickens should be fed on cheap, rough rice with the outer coverings still on the grain.
Eijkman noticed that the chickens began to recover on the new diet. He began to consider the possibility that eating unmilled rice (糙米) somehow prevented or cured beri-beri--even that a lack of some ingredient (成分) in the coverings may be the cause of the disease. Indeed this was the case. The element needed to prevent beri-beri was shortly afterwards separated from rice coverings and is now known as vitamin B. The milled rice, though more expensive, was in fact causing the disease the hospital was trying to cure. Nowadays, this terrible disease is much less common thanks to our knowledge of vitamins.

Millions of people visit Yosemite National Park every year to see the tall waterfalls and mountains. These mountains are a splendid sight when viewed form the valley floor. Lots of stores, hotels, and restaurants are needed to handle the crowds. Also, water, roads, and other service systems are part of the infrastructure (基础设施) that must be maintained.
Unfortunately, these systems are starting to break down. It’s not just in Yosemite but in national parks around the nation.
Yosemite is thirty years old according to Dennis Galvin, a National Park Service worker. The Park is not only old but worn out. Two or three times as many visitors come every year. That is too many visitors for the park to deal with.
Four years ago a storm washed out a water pipeline in the Grand Canyon. The National Park Service had to send water trucks to provide water for the visitors. Last month pipes almost broke again and roads had to be closed for a while.
Why hasn’t the National Park Service kept up the park repairs? There is a lack of money. The United States has 378 monuments, parks, and wilderness areas. Between three and four billion dollars are needed for repairs.
Yosemite is one national park that does have money for repairs. It has two hundred million dollars but cannot spend it any way it chooses. When the park workers started widening the road, they were forced to stop by the Sierra Club. The club claimed that the road work was damaging the Merced River that runs through the park.
A sierra Club lawyer, Julia Olson, feels that the infrastructure needs to be moved out of Yosemite. That way less pressure will be put on the already crowded park.
65. According to the text, the mountains in Yosemite look most splendid when they are appreciated from ______.
A. the bottom of the valleys B. the top of the mountains
C. the side of the mountains D. the edge of the valleys
66.National parks like Yosemite in the U.S. find it increasingly difficult to meet the need of
visitors because ______.
A. their transport management needs improving
B. they spend too much on their service systems
C. their service systems frequently go out of order
D. they need help from environmental organizations
67.The main problem of Yosemite National Park is its ______.
A. rundown water pipes B. overcrowdedness
C. lack of money D. narrow roads
68. According to the text, the Sierra Club is most likely to be ______.
A. an environmental group B. an information center
C. a travel service D. a law firm
