She took up skating at age 85, made her first movie appearance at age 114, and held a concert in the
neighborhood on her 121 st birthday.
When it comes to long life, Jeanne Calment is the world"s recordholder. She lived to the ripe old age of
122. So is 122 the upper limit to the human life span (寿命)? If scientists come up with some sort of pill or
diet that would slow aging, could we possibly make it to 150－or beyond?
Researchers don"t entirely agree on the answers. "Calment lived to 122, so it wouldn"t surprise me if
someone alive today reaches 130 or 135," says Jerry Shay at the University of Texas.
Steve Austad at the University of Texas agrees."People can live much longer than we think," he says.
"Experts used to say that humans couldn"t live past 110. When Calment blew past that age, they raised the
number to 120. So why can"t we go higher?"
The trouble with guessing how old people can live to be is that it"s all just guessing."Anyone can make
up a number,"says Rich Miller at the University of Michigan. "Usually the scientist who picks the highest
number gets his name in Time magazine."
Won"t new anti-aging techniques keep us alive for centuries? Any cure, says Miller, for aging would
probably keep most of us kicking until about 120. Researchers are working on treatments that lengthen the
life span of mice by 50 percent at most. So, if the average human life span is about 80 years, says Miller,
"adding another 50 percent would get you to 120."
So what can we conclude from this little disagreement among the researchers? That life span is flexible
(有弹性的), but there is a limit, says George Martin of the University of Washington." We can get flies to
live 50 percent longer,"he says. "But a fly"s never going to live 150 years."Of course, if you became a new
species (物种), one that ages at a slower speed, that would be a different story, he adds.
Does Martin really believe that humans could evolve (进化)their way to longer life?"It"s pretty cool to
think about," he says with a smile.
B. Old people are creative.
C. Women are sporty at 85.
D. Women live longer than men.
B. scientists cannot find ways to slow aging
C. few people can expect to live to over 150
D. researchers are not sure how long people can live
B. Steve Austad
C. Rich Miller
D. George Martin
B. The average human life span cannot be doubled
C. Scientists believe mice are aging at a slower speed than before.
D. New techniques could be used to change flies into a new species

summer and turned their attention to scientific experiments.
The High School Research Program offers high school students guidance with researchers in Texas
A&M"s College of Agriculture and Life Sciences. Jennifer Funkhouser, academic adviser for the Department
of Rangeland Ecology and Management, direst this four-week summer program designed to increase
understanding of research and its career potential (潜能).
Several considerations go into selecting students, including grades, school involvement and interest in
science and agriculture. And many students come from poorer school districts, Funkhouser says. "This is
their chance to learn techniques and do experiments they never would have a chance to do in high school."
Warner Ervin of Houston is interested in animal science and learned how to tell male from female
mosquitoes(蚊子). His adviser, Craig Coates, studies the genes of mosquitoes that allow them to fight
against malaria and yellow fever. Coates thought this experience would be fun and helpful to the high school
students.
The agricultural research at A&M differs from stereotypes. It"s "molecular (分子) science on the cutting
edge," Funkhouser says. The program broadened students" knowledge. Victor Garcia of Rio Grande City
hopes to become a biology teacher and says he learned a lot about chemistry from the program.
At the end of the program, the students presented papers on their research. They"re also paid $600 for
their work-another way this program differs from others, which often charge a fee.
Fourteen students got paid to learn that science is fun, that agriculture is a lot more than milking and
plowing and that research can open many doors.
B. college students majoring in agriculture
C. high school students from different places

Mellor of Rhode Island will spend the next year as an international spokeswoman for education. President
Bush and his wife, Laura, honored her during a ceremony (仪式) at the White House last week.
For the past nineteen years, Kathy Mellor has taught English as a second language at Davisville Middle
School in North Kingstown, Rhode Island,in the northeastern United States.She redesigned the program for
E.S.L students at her school to provide each student with one to three periods per day in classes for English
learners. How much instruction the students get depends on their level of skill in listening,speaking, reading
and writing. The amount of time they spend in these classes in reduced as their level of English increases.
A teacher describes this as the most successful E.S.L. program in North Kingstown. She also praises
Kathy Mellor for providing help to students and their families by forming a local parents group for speakers
of other languages.This improved their ability to help their children.
Kathy Mellor earned a master"s degree in education from Rhode Island College. She studied teaching
English as a second language.
She was chosen for the national honor of Teacher of the Year from among top teachers in each of the
fifty states. As Teacher of the Year, Kathy Mellor will travel around the United States and to other countries.
She will talk about the importance of education and the work of teachers.
B. Ms Mellor"s English teaching instruction
C. Ms Mellor"s teaching skills of learning English
D. praises to Ms Mellor from other teachers
B. English speaking and listening.
C. English special learners.
D. English as a second language.
B. middle school teachers in the USA have to get master"s degrees
C. Ms Mellor"s students have no problems in learning English
D. the American government pays much attention to education
The gray-haired lady can"t wait to leave the building to search for her dad.Unless watched, she will
walk in the streets in an effort to find her father,who died 30years ago.
Not all cases of Alzheimer"s disease look like this,but Alzheimer"s is a serious disease that is said to be
the fourth or fifth leading cause of death for people over age 75.
It is said that about three percent of the U.S. population over age 65 have Alzheimer"s.In the early stages,
people may exhibit short term memory loss. Some may experience changes in personality, easy to be angry.
As the disease progresses, patients might lose the ability to move and may be unable to speak or move at all.
This progressive disease generally lasts 8 to 10 years before death occurs.
While no one is certain what causes these changes in the brain"s nerve fibers (神经纤维), their effect is
certain. Alzheimer"s destroys not only the patients, but also spouses (配偶), friends and families.
What should you do if you notice progressive memory loss in yourself or a loved one? Have the person
examined by a doctor who is a specialist in the treatment of Alzheimer"s disease. Though many reasons other
than Alzheimer"s disease may cause memory loss,its early diagnosis (诊断) and treatment may delay some of
the most serious effects.
What feeling will you likely experience should a loved one suffer from Alzheimer"s disease? A person will
often go through the various stages of sadness, shock, anger, and so on. If the spouse develops the disease,
you may experience hurt and disappointment when he or she doesn"t remember you are married.
Life for the Alzheimer"s patients and their loved ones will never be the same as the disease progresses,
bringing a deep sorrow, loss and even anger towards God. No matter what feelings are present, facing them
honestly will serve one better than burying them.
B. She was sad about the death of her father.
C. She can"t search for her father without being watched.
D. She suffers from Alzheimer"s disease.
B. their families and friends will experience mental sufferings
C. they will certainly die in 8 to 10 years
D. they will forget everybody but their spouses
B. from sadness,shock,anger,and so on
C. for a number of reasons
D. with changes in personality
B. it is still unknown what causes the changes in the brain"s nerve fibers
C. nerve fibers in the brain will cause Alzheimer"s disease
D. when one suffers from Alzheimer"s disease,he will be buried

enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
"I think we are knocking at the door of immortality (永生)," said Michael Zey, a Montclair State University
business professor and author of two books on the future. "I think by 2075 we will see it and that"s a
conservative estimate (保守的估计)."
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark
said advances in using genes as well as nanotechnology (纳米技术) make it likely that humans will live in the
future beyond what has been possible in the past. "There is a great push so that people can live from I20 to
180 years," he said. "Some have suggested that there is no limit and that people could live to 200 or 300 or
500 years."
However, many scientists who specialize in ageing are doubtful about it and say the human body is just not
designed to last past about 120 years. Even with healthier lifestyles and less disease, they say failure of the
brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live."It remains to be seen if you pass 120,
you know; could you be healthy enough to have good quality of life?" said Leonard Poon, director of the
University of Georgia Gerontology Centre. "At present people who could get to that point are not in good health
at all."
B. they are sure to find the truth about long living
C. they have got some ideas about living forever
D. they are able to make people live past the present life span
B. it is still doubtful how long humans can live

D. it is possible for humans to live longer in the future
B. the idea of living beyond the present life span
C. the idea of living from 200 to 300 years
D. the conservative estimate
B. Science, Technology and Long Living
C. No Limit for Human Life
