The rising costs of health care have become a problem for many countries in the world. To deal with this problem, it is recommended that a big part of the government's health budget be used for health education and disease prevention instead of treatment. Actually, many kinds of diseases are preventable in many ways and preventing a disease is usually much cheaper than treating it. For example, people could avoid catching a cold if they dressed warmly when the weather starts getting cold. But many people get sick because they fail to do so, and have to spend money seeing a doctor.

Daily habits like eating more healthy food would have kept millions of families from becoming bankrupt if the patients had taken measures for early prevention. For instance, keeping a balanced diet, such as not consuming too much animal fat and insuring a steady intake of vegetables and fruits, seems to be quite important.

One very effective and costless way of prevention is regular exercise, which is necessary for a healthy mind and body. Regular exercise, such as running, walking, and playing sports is a good way to make people feel better or reduce stress.

In addition, health education plays a key role in improving people's health. By giving people more information about health, countries could help people understand the importance of disease prevention and ways to achieve it. For example, knowing one's family medical history is an effective way to help keep healthy. Information about health problems among close relatives will make them aware of what they should do to prevent certain diseases through lifestyle changes, which will work before it is too late.

However, stressing disease prevention does not mean medical treatment is unimportant. After all, prevention and treatment are just two different means toward the same effect. In conclusion, we could save money on health care and treat patients more successfully if our country spends more money on health prevention and education.

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.

阅读下列短文，从每题题所给的四个选项（A、B、C、D和E）中选出最佳选项。
Sitting too much is now listed with smoking and junk food as a bad habit that increases your risk of heart disease.
New Australian research shows that half-an-hour in the gym will not make up for the waist-expanding damage caused by spending the rest of the day sitting.
But the good news is that doing chores in the house or gently walking around the office while on the phone might be enough to keep you fit.
The study joins the growing body of evidence suggesting too much sitting might undo the benefits of exercise.
The study measured the intensity of physical activities in 168 subjects over seven days. It found that, regardless of how much exercise they did or their total sitting time, those who took more breaks from sitting had lower risk of thick waists and lower levels of blood lipids(脂肪).
“Higher levels of blood lipids have been linked to a heightened risk of heart disease,” principal researcher Genevieve Healy of the University of Queensland said. “What the study shows is that there are benefits in just getting up regularly and interrupting your sitting time.”
Researchers behind the Stand Up Australia project have written to the Rudd Government requesting $3.5 million for a two-year study into the impact of long sitting time on health and productivity of workers. The study would also develop and test strategies for reducing sitting time on the job.
The latest study builds on work that is shifting the health promotion focus from purposeful exercise, such as running, to lower intensity activities throughout the day.
The Australian research has been hacked up by US studies.
“To hold a body that weighs 77 kilograms upright takes a fair amount of energy from muscles,” said Professor Marc Hamilton from the University of Missouri. “There is a large amount of energy associated with standing every day that cannot easily be replaced by 30 to 60 minutes in the gym.”
56. What’s the aim of the Stand Up Australia project?
A. To study the factors influencing productivity of workers.
B. To study the reasons for the longer sitting time at work.
C. To develop and test strategies for reducing sitting time in the office.
D. To develop and test strategies for reducing working time.
57. The purpose of the last paragraph is to .
A. provide a scientific basis for the benefits of standing up
B. Compare the effect of standing with exercising in the gym
C. report the new research findings of professor Marc Hamilton
D. figure out the amount of energy associated with daily standing
58. What’s the best title for the text?
A. Exercise in the Gym Is Out.
B. Your Office Chair Is Killing You.
C. A Cause of Heart Disease.
D. Good News for Workers.

Where on Earth are you? Navigators (导航员) use lines of latitude and lines of longitude to locate places. Lines of latitude run east and west around Earth. On a map or globe, these lines appear as running sideways or horizontally. Lines of longitude run north and south around Earth. These lines go up and down or vertically on a map or globe. These lines create an imaginary graph paper on the Earth. They make it possible to find an absolute, or exact, location on Earth. They even allow us to give an absolute location to a place out in the middle of the ocean.

Lines of latitude tell us how far north or south of the Equator we are. Sailors have used primitive navigation tools, like astrolabes, since ancient times. The astrolabe uses the sun and stars to find an approximate location. Using such tools, they have been able to approximate their distance from the equator. Although their instruments may not have been the high quality we have now, they were incredibly accurate (精确) for their time.

Lines of longitude tell us how far east or west of the prime meridian (本初子午线) we are. Sailors constantly looked for new ways to increase their navigation skills. Still, it wasn’t until the 18th century that they were able to measure degrees of longitude. They would have been very envious of the technology available to us today.

When we use lines of latitude and longitude together, we can get a very precise location. If we want to identify the absolute location of a point, we look where the latitude and longitude lines cross nearest to that point. We use the coordinates (坐标) for that point as its address. Many maps today include degrees of latitude and longitude.

1.______ make it possible for people to find an exact place on Earth.

A．Latitudes B．Longitudes C．Navigators D．Sailors

2.The second paragraph mainly talks about _______.

A．the function of latitude B．the use of the equator

C．the invention of astrolabe D．the high quality instruments

3. Why do maps include degrees of latitude and longitude?

A．To help trade expeditions. B．To locate a precise place.

C．To cross the lines of the nearest point. D．To identify how far a place is.

4.The best title for this passage is ____________.

A．The map and the globe B．Latitude and longitude

C．The equator and the prime meridian D．Absolute coordinates
