12．Sugar gives quick relief to hunger but provides no lasting nourishment ．——青夏教育精英家教网—

9．Researchers in the psychology department at the University of California at Los Angeles （UCLA） have discovered a major difference in the way men and women respond to stress．This difference may explain why men are more likely to suffer from stress-related disorders．
Until now，psychological research has maintained that both men and women have the same"fight-or-flight"reaction to stress．In other words，individuals either react with aggressive behavior，such as verbal or physical conflict （"fight"），or they react by withdrawing from the stressful situation （"flight"）．However，the UCLA research team found that men and women have quite different biological and behavioral responses to stress．While men often react to stress in the fight-or-flight response，women often have another kind of reaction which could be called"tend and befriend．"That is，they often react to stressful conditions by protecting and nurturing their young （"tend"），and by looking for social contact and support from others-especially other females （"befriend"）．
Scientists have long known that in the fight-or-flight reaction to stress，an important role is played by certain hormones（激素） released by the body．The UCLA research team suggests that the female tend-or-befriend response is also based on a hormone．This hormone，called oxytocin，has been studied in the context of childbirth，but now it is being studied for its role in the response of both men and women to stress．The principal investigator，Dr．Shelley E．Taylor，explained that"animals and people with high levels of oxytocin are calmer，more relaxed，more social，and less anxious．"While men also secrete （分泌） oxytocin，its effects are reduced by male hormones．
In terms of everyday behavior，the UCLA study found that women are far more likely than men to seek social contact when they are feeling stressed．They may phone relatives or friends，or ask directions if they are lost．
The study also showed how fathers and mothers responded differently when they came home to their family after a stressful day at work．The typical father wanted to be left alone to enjoy some peace and quiet．For a typical mother，coping with a bad day at work meant focusing her attention on her children and their needs．
The differences in responding to stress may explain the fact that women have lower frequency of stress-related disorders such as high blood pressure or aggressive behavior．The tend-and-befriend regulatory（调节的） system may protect women against stress，and this may explain why women on average live longer than men．

Many Chinese students are unfamiliar with the idea of a liberal-arts education----an approach to learning that's common at US universities．It's a（41）D that exposes a student to a wide range of subjects instead of focusing on technical skills．The most important goal is to （42）F a student's character．
The theory of a liberal-arts college is that a student goes through four years of school focusing on （43）B and personal development and gaining a broad knowledge of the world．After that，he can continue with law，business or graduate school to obtain a specific skill．Once he has developed good character，he will be able to （44）A whatever he wishes．
The education can shape a student's ability to make choices in the future by fostering two （45）H skills：how to learn things on his own and how to think critically．The old Chinese saying is right：It's better to teach someone how to fish than to give him fish．The liberal-arts curriculum can empower a student to seek knowledge outside the classroom and not to be afraid of the （46）K．
Another key aspect of a liberal-arts education is that it helps to develop critical thinking．In other words，it teaches a student how to （47）C conflicting information or views and form his own opinions．It inspires him to dig deeper and challenge what is presented to him．
After receiving a liberal-arts education，he will never accept that things are as they should be．He wants to find out why something is the way it is．This type of education encourages him to always pursue the"why"．Once he understands the why，he will better understand the fundamentals and have a deeper （48）I of whatever subject he is pursuing．This desire to question things continuously---including one's own ideas and life---is an important aspect of someone's （49）E．
Figuring out who you are and what you're capable of is the best part of a liberal-arts education．It's a （50）G of self-motivation and self-awareness．

Imagine life as a game in which you are juggling five balls in the air．You name them：work，family，health，friends，and spirit，and you're keeping all of them in the air．You will soon understand that work is a （41）Jball．If you drop it，it will bounce back．But the other four balls---family，health，friends，and spirit are made of glass．If you drop one of these，they will be irrevocably scuffed，marked，nicked，damaged，or even shattered．They will never be the same．You must understand that and （42）I for balance in your life．
How？Don't undermine your worth by （43）C yourself with others．It is because we are different that each of us is special．Don't set your（44）Gby what other people deem important．Only you know what is best for you．Don't take for granted the things closest to your heart．（45）E to them as you would to life，for without them，life is meaningless．Don't let life slip through your fingers by living in the past or for the future．By living your life one day at a time you live all the days of your life．Don't give up when you still have something to give．Nothing is really over until the moment you stop trying．Don't be afraid to admit that you are （46）Fperfect．It is this fragile thread that binds us together．Don't be afraid to encounter risks．It is by taking chances that we learn to be brave．Don't shut love out of your life by saying it's （47）D to find．The quickest way to receive love is to give； the fastest way to lose love is to hold it too （48）H； and the best way to keep love is to give it wings．Don't run （49）Blife so fast that you forget not only where you've been，but also where you are going．Don't forget that a person's greatest emotional need is to feel appreciated．Don't use time or words carelessly．Neither can be retrieved．Life is not a race，but a journey to be savored each step of the way．

6．What will people die of 100years from now？If you think that is a simple question，you have not been paying attention to the revolution that is taking place in bio-technology（生物技术）．With the help of new medicine，the human body will last a very long time．Death will come mainly from accidents，murder and war．Today's leading killers，such as heart disease，cancer，and aging itself，will become distant memories．
In discussion of technological changes，the Internet gets most of the attention these days．But the change in medicine can be the real technological event of our times．How long can humans live？Human brains were known to decide the final death．Cells（细胞） are the basic units of all living things，and until recently，scientists were sure that the life of cells could not go much beyond l20years because the basic materials of cells，such as those of brain cells，would not last forever．But the upper limits will be broken by new medicine．So metime between 2050and 2100，medicine will have advanced to the point at which every 10years or so，people will be able to take medicine to repair their organs （ The medicine，made up of the basic building materials of life，will build new brain cells，heart cells，and so on-in much the same way our bodies make new skin cells to take the place of old ones．
It is exciting to imaging that the advance in technology may be changing the most basic condition of human existence，but many technical problems still must be cleared up on the way to this wonderful future．
