Is there a way to turn back the aging process in people? For centuries, people have been looking for a “fountain of youth.” The idea is that if you find a magical fountain, and drink its water, you will not age.
Researchers in New York did not find an actual fountain of youth, but they may have found a way to turn back the aging process. It appears that the answer may be called the hypothalamus, which is part of your brain. It controls important body activities, including growth, the way we process food and so on.
Researchers at New York’s Albert Einstein College of Medicine found that hypothalamus neural stem cells (干细胞) also influence how fast aging takes place.
Dongsheng Cai, a professor at the Albert Einstein College of Medicine, was the leading researcher in a study on aging in mice. He and his team reported their findings.
“Aging speed can be controlled by a particular place in the body, which is the hypothalamus. And it can be controlled by a particular type of cells, which are hypothalamus stem cells.” He adds that when the hypothalamus starts aging, so does the body. So when hypothalamus function is in decline, particularly the loss of hypothalamus stem cells, and this protection against the aging development is lost, it eventually leads to aging.
Using this information, the researchers began trying to activate the hypothalamus in laboratory mice. They did this by injecting the animals with stem cells.
The researchers say the results show that the treatment slowed aging in the animals. “When we injected the hypothalamus stem cells to the middle-aged mice, the mice aged slowly and they can also live longer.”
But these results were just from studying mice in a laboratory. If the mice can live longer, does that mean people could have longer lives? The next step is to see if the anti-aging effects also work in human beings.
“If we can translate what we have seen in animals to humans, I think humans can function better during later ages.” Cai and his team say their studies may have other benefits. They say the findings could lead to new ways to help doctors identify and treat any number of age-related health issues.
1.Why does the author mention the “fountain of youth” in the first paragraph?
A. To explain what the “fountain of youth” is.
B. To introduce the hypothalamus.
C. To show how to find the “fountain of youth”.
D. To help people find the “fountain of youth”.
2.What does the underlined word “it” in Paragraph 2 refer to?
A. The brain. B. The aging process.
C. Hypothalamus. D. The stem cell
3.What do we know about the study done by Cai?
A. They have found a way to turn back the aging process.
B. The brain controls growth, reproduction and the way we process food.
C. The decrease of hypothalamus stem cells can lead to aging.
D. The finding has been applied to human beings.
4.Which of the following can be the best title of the passage?
A. The Fountain of Youth
B. A New Discovery about Aging
C. The Ways of Slowing Down Aging
D. Hypothalamus—the Fountain of Youth

There are two basic ways to see growth: one as a product, the other as a process.People have
generally viewed personal growth as an external (外在的) result or a product that can easily be
identified and measured.The worker who gets a rise, the student whose grades improve, the
foreigner who learns a new language—all these examples of people who have measurable results to
show for their efforts.
By contrast (对照) , the process of personal growth is much more difficult to determine, since
it is a journey and not the specific signposts or landmarks along the way.The process is not the road itself, but the attitudes, feelings people have , and their caution or courage, as they meet with new experiences and unexpected difficulties.In this process, the journey never really ends;there are always new ways to experience the world, new ideas to try, new challenges to accept.
In order to grow, to travel new roads, people need to have a willingness to take risks, to face the unknown, and to accept the possibility that they may “fail” at first.How we see ourselves as we try a new way of being is necessary for our ability to grow.Do we see ourselves as quick and curious? If so, we tend to take more chances and be more open to unfamiliar experiences.Do we think we’re shy and indecisive? Then our sense of fear can cause us to hesitate, to move slowly, and we think we are slow to adapt change or that we’re not smart enough to deal with a new challenge.Then we are likely to take a more passive role or not try at all.
These feelings of insecurity and self-doubt are both unavoidable and necessary if we are to
change and grow.If we protect ourselves too much, then we stop growing.We become trapped inside a shell of our own making.
1.In the author’s eye, one who views personal growth as a process would ____.
A.succeed in climbing up the social ladder
B.grow up from his own achievements
C.face difficulties and take up challenges
D.aim high and reach his goal each time
2.Which of the following can be viewed as the process of personal growing?
A.Our manager was always willing to accept new challenges.
B.Jane won the first prize in the speech competition.
C.Jerry picked up French during his stay in Paris.
D.Father’s salary rose from 5, 000 to 7,000.

高三英语阅读理解中等难度题查看答案及解析
There are two basic ways to see growth: one as a product, the other as a process. People have generally viewed personal growth as an external(外部的) result or product that can easily be identified and measured. The worker who gets a promotion, the student whose grades improve, the foreigner who learns a new language--- all these are examples of people who have measurable results to show for their efforts.
By contrast, the process of personal growth is much more difficult to determine, since by definition it is a journey and not the specific signposts (路标)or landmarks along the way. The process is not the road itself, but rather the attitudes and feelings people have, their caution or courage, as they go through new experiences and unexpected obstacles(阻碍). In this process, the journey never really ends; there are always new ways to experience the world, new ideas to try, new challenges to accept.
In order to grow, to travel new roads, people need to have a willingness to take risks, to be faced with the unknown, and to accept the possibility that they may “fail” at first. How we see ourselves as we try a new way of being is essential(基本的) to our ability to grow.
These feelings of insecurity and self – doubt are both unavoidable and necessary if we are to change and grow. If we do not face and overcome these internal(内部的) fears and doubts, if we protect ourselves too much, then we cease(停止) to grow. We become trapped inside a shell of our own making.
1..A person is generally believed to achieve personal growth when______..
A.he has given up his smoking habit
B.he has made great efforts in his work
C.he is interested in making anything new
D.he has tried to determine where he is on his journey
2..In the author’s eyes, one who views personal growth as a process would______.
A.judge his ability to grow from his own achievements
B.succeed in climbing up the social ladder
C.face difficulties and take up challenges
D.aim high and reach his goal each time
3..When the author says “a new way of being” (para. 3), he is referring to _____.
A.a new way of taking risks
B.a new approach to experiencing the world
C.a new system of adapting to change
D.a new method of finding ourselves
4..For personal growth, the author may not support __________. .

高三英语阅读理解中等难度题查看答案及解析
Reading instruction in the classroom is a key concern for all teachers and there are many ways to go about it. However, is our determination to achieve excellence in reading skills in our children killing their love and enjoyment of a good book?
In my work with parents, I am frequently asked the best ways to encourage reluctant readers to be engaged with books. Parents report that their children return home from school with no inclination to pick up a book and read.
Any eager reader will gladly talk about the joy with a good book to read away the hours on a cold, rainy afternoon. Reading a good book is one of life’s greatest pleasures. We need to share these experiences with our children in order to assist them in developing into strong readers. But the use of boring, mass-produced home reading texts in children’s early years at school can be seen as the beginning of this negative cycle.
As children progress through their schooling life, there are many other instances of learning reading skills that don’t help reading development. Frequently, teachers feel the pressure to give their students “just enough” in terms of reading strategies to be able to achieve the test, which leaves little time to focus on reading for pleasure.
Kelly Gallagher, a high school teacher, outlines the term “Readicide” in his book. He says it’s: the systematic killing of the love of reading, often worsened by foolish, boring practices found in schools.
Recent research shows that many teachers tend to follow the traditional literacy practices that they have experienced in their own education, which can often have negative intentions for their students.
While teaching children key concepts for analyzing and evaluating texts is important, the manner in which it is done and time that is spent on this can lead to unexpected results. Schools aren’t to blame when it comes to not arresting students’ lack of interest in reading, but they have an important role to play in fostering reading enjoyment.
1.What does the underlined word “inclination” mean?
A.Energy B.Task
C.Intention D.Requirement
2.What does the term “Readicide” refer to?
A.To develop reading habits B.To read for pleasure
C.To learn reading skills D.To kill a love for books
3.According to the text, teachers at school ______.
A.focus on teaching reading strategies
B.ignore key concepts for analyzing texts
C.are to blame for students’ poor reading
D.fail to follow the traditional reading practices
4.What might be suitable title for the text?
A.Reading books is to experience pleasure
B.Learning to love books is even more important
C.Teaching reading helps reluctant readers
D.Getting pleasure from books makes capable readers
