　　Happy birthday! Do birthdays really make people happy? Of course they do. Birthdays celebrate the day we were born. What's more, that extra candle on the cake represents another year of growth and maturity (成熟)—or so we hope. We all like to imagine that we're getting wiser and not just alder. Most of us enjoy observing the miracle of growth in others as well. For instance, seeing our children develop and learn new things makes us feel proud. For Americans, like people in most cultures, growing up is a wonderful process. But growing old? That's a different story. Growing old is not exactly pleasant for people in youth-oriented American . Most Americans like to look young, act young and feel young. As the old saying goes, “You're as young as you feel . ” Older people joke about how many years young they are ,rather than how many years old. People in sane countries value the aged as a source of experience and wisdom. But Americana seem to favor those that are young, or at least “young at heart”. Many older Americans find the“golden years” to be anything but golden. Economically, “senior citizens”often struggle just to get by. Retirement — typically at age 65—brings a sharp decrease in personal income. Social Security Benefits usually cannot make up the difference. Older people may suffer from poor nutrition(营养) , medical care and housing. Some even experience age discrimination.

　　Ironically, the elderly population in America is expanding fast. Why? People are living longer. Fewer babies ere being born. The middle-aged “baby boomers” are rapidly entering the ranks of the elderly, so America may soon be a place where wrinkles(皱纹) are “in” . Marketing experts are already focusing on this growing group of consumers. And even now the elderly have a great deal of political power.

　　A common stereotype(模式化的形象) of older Americana is that they are usually “put away” in nursing homes and forgotten about. Actually, only about 5 percent live on acme type of institution(慈善机构).

　　More than half of those 65 or older live with or near at least one of their children. The vast majority ad the elderly live alone and take care of themselves.

　　In spite of challenges they face, Americans in their “twilight years (暮年)” generally refuse to we up on life. They find a variety of ways to keep themselves active. To help them stay in shape, they may join mall (商业区) walkers club, fitness programs and even the “Senior Olympics” .They can enjoy hours of entertainment at senior centers and adult amusement parks. Many enroll in continuing education programs to maintain their mental skills. For Americans, if you're going to grow old, you might as well do it gracefully.

      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.

64．Which of the following may be the title for the passage?

       A．Science, sports and exercise

       B．Correct iron deficiency

       C．Women, Iron and exercise

       D．Women, health and exercise

       A．organizing the details according to the order of time

       B．presenting the result followed by specific causes

       C．beginnign with details followed by a general statement

       D．making comparisons ad contrasts

66．What does it mean when you are in the third stage of iron defieiency?

       A．Nothing serious though you don’t have much iron stored in the body.

       B．There is not enough iron to form the molecules of blood protein to transport oxygen.

       C．The small blood vessels in your reet are beginnig to leak blood.

       D．No iron is ldft in your body and you would be in trouble without urgent measures.

67．What is the writer’s attitude in writing this passage?

It is believed that it took about 800 thousand to 1 million years for the earth's population to reach the 250 million total which existed at the end of the first century AD. For some time after that, disease, famine(饥饿) and war kept the population increase down to a rate of 1 percent a year so that more than 15 centuries passed before the population reached 500 million. But in the next 250 years, up to 1850, the population of the world shot to 1 billion and today it has reached 3.5 billion. Scientists say that in the next 35 years the population of the world will double, reaching almost 7 billion by the year 2010.
When experts are asked what are the most effective measures that can stop over population, they reply that at least three measures can be considered.
(A) Increasing sources and supply of food for under-developed countries.
(B) Increasing the industrialization of under- developed countries.
(C) Controlling birth.
The experts add, however, that none of the above measures can be effective by itself, and that all must be combined into one whole program. They also agree that without controlling of births, any other measures are doomed (注定) to failure.
