by memory of all the basic things one must know is a most incredible and unending effort. School is not easy and it is not for the most part very much fun, but then, if you are very lucky, you may find a real teacher. Three teachers in a lifetime are the very best of my luck. My first was a science and math teacher in high school, my second, a professor of creative writing at Stanford, and my third was my friend and partner, ED Rickets.
I have to believe that a great teacher is a great artist and that three are as few as there are any other great artists. It might even be the greatest of the arts since the medium is the human mind and spirit.
My three teachers had these things in common: They all loved what they were doing; they did not tell, but stimulated a burning desire to know. Under their influence, the horizons sprang wide and fear went away and the unknown became knowable.
I shall speak only of my first teacher because in addition to the other things, she brought discovery. She aroused us to shouting, book-waving discussions. She had the noisiest class in school and she did not even seem to know it. We could never stick to the subject. Our speculation (思绪) ranged the world. She breathed curiosity into us so that we brought in facts or truths shielded in our hands like captured fireflies (萤火虫).
She was fired, and perhaps rightly so, for failing to teach fundamentals. Such things must be learned. But she left a passion in us for the pure knowable world and she inflamed me with a curiosity which has never left. I have had many teachers who told me soon-forgotten facts but only three who created in me a new attitude a new hunger. What deathless power lies in the hands of such a person？
21. In the writer’s opinion, school life is usually .
A. exciting B. interesting C. tiresome D. challenging
22. We can infer from Paragraph 2 that .
A. it is easy to find great artists as well as great teachers.
B. there are few great teachers but many great artists.
C. the greatest artists are not easy to find; nor are the greatest teachers.
D. being a great teacher is a great art to learn because teachers spread knowledge.
23. In the writer’s opinion, a good teacher should .
A. teach students the fundamental things
B. stick to one subject and be strict with students
C. teach students the knowledge ranging the world
D. arouse students’ curiosity and desire for the world

A. her class was the noisiest in school
B. she did not teach basic knowledge in class
C. she let students shout and wave books in class
D. she did not know how to teach basic knowledge effectively
25. What is the best title of this article？

C. What to Teach at School D. What Makes a Good Teacher
On the other hand, scientists are increasingly learning that aging and biological age are two different things, and that the former is a key risk factor for conditions such as heart disease, cancer and many more. In that light, aging itself might be seen as something treatable, the way you would treat high blood pressure or a vitamin deficiency.
Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that describing aging as a disease creates incentives to develop treatments.
"It unties the hands of the pharmaceutical (制药的.industry so that they can begin treating the disease and not just the side effects," he said.
"Right now, people think of aging as natural and something you can't control," he said. "In academic circles, people take aging research as just an interest area where they can try to develop interventions. The medical community also takes aging for granted, and can do nothing about it except keep people within a certain health range."
But if aging were recognized as a disease, he said, "It would attract funding and change the way we do health care. What matters is understanding that aging is curable."
"It was always known that the body accumulates damage," he added. "The only way to cure aging is to find ways to repair that damage. I think of it as preventive medicine for age-related conditions."
Leonard Hayflick, a professor at the University of California, San Francisco, said the idea that aging can be cured implies the human lifespan can be increased, which some researchers suggest is possible. Hayflick is not among them.
"There're many people who recover from cancer, stroke, or heart disease. But they continue to age, because aging is separate from their disease," Hayflick said. "Even if those causes of death were eliminated, life expectancy would still not go much beyond 92 years."
66.What do people generally believe about aging______
A.It should cause no alarm whatsoever.
B.They just cannot do anything about it.
C.It should be regarded as a kind of disease.
D.They can delay it with advances in science.
67.How do many scientists view aging now______
A.It might be prevented and treated.
B.It can be as risky as heart disease.
C.It results from a vitamin deficiency.
D.It is an irreversible biological process.
68.What does Alex Zhavoronkov think of "describing aging as a disease"______
A.It will prompt people to take aging more seriously.
B.It will greatly help reduce the side effects of aging.
C.It will free pharmacists from the conventional beliefs about aging.
D.It will motivate doctors and pharmacists to find ways to treat aging.
69.What do we learn about the medical community______
A.They now have a strong interest in research on aging.
B.They differ from the academic circles in their view on aging.
C.They can contribute to people's health only to a limited extent.
D.They have ways to intervene in people's aging process.
70.What does professor Leonard Hayflick believe______
A.The human lifespan cannot be prolonged.
B.Aging is hardly separable from disease.
C.Few people live up to the age of 92.
D.Heart disease is the major cause of aging.
A、Werner's syndrome is a premature aging illness, possibly caused by a defect in DNA repair.
B、Dietary restriction in mammals reduces the production of DNA damaging free radicals in the mitochondria.
C、Senescent cells in culture that have stopped dividing often express p21 and p16, proteins that are normally activated in response to DNA damage.
D、All of these facts are consistent with a model for aging based on DNA damage.
Biologists today don’t expect that anyone will find a magical fountain of youth.Growing older is a natural part of the life cycle that can’t be reversed.As human beings grow older, organs such as the heart and lungs may stop functioning properly.Sight and hearing may become weak.And the human body becomes more likely to come down with serious illnesses from which it cannot recover.
Considered together, changes that bring about the decline of an organism are called aging.Because of aging, many biologists believe that there may be a maximum age limit to which even the healthiest organisms can live.For human beings, this maximum age limit is about 110 years.
Perhaps the most important thing that you can learn from your study of human biology is that you have a lot of control over the aging process in your own life.In fact, within our control are many physical and mental factors that have much to do with aging.For example, each of us, as recent research indicates, can do many things to help prevent heart and vessel disease, which causes half the death each year in the United States.We can avoid eating a lot of fatty meat.Eating too much of these types of animal fats can lead to the clogging and hardening of blood vessels.We can cut back on smoking and hopefully quit entirely.We can limit the amount of alcohol we drink and the amount of sugar we eat.We can exercise regularly and strengthen the heart and other organs.And we can remember to take time out each day for ourselves, time just relax.Exercise, recreation and relaxation all reduce stress – inner tension that is hard on all body organs.
One final thing we can do is to try to keep aware of advances made in health education.Information is often available free of charge from health clinics or schools.
