1．Eating 40 percent less food could extend a person's life by 20 years，according to scientists．
Researchers at the Institute of Health Ageing at University College London are developing a treatment that they hope will fight the"disease" of getting older．
They are looking into how genetics （遺傳學(xué)） and lifestyle can affect ageing and add years，possibly decades，to a person's life．
Agerelated diseases such as cardiovascular disease，cancer and neurodegeneration can also be treated，it is claimed．
They want to find out how the life of a rat can be increased by up to 30 percent simply by reducing its food intake．
Researcher Dr．Piper told the Independent，"If you reduce the diet of a rat by 40 percent it will live for 20 or 30 percent longer．So we would be talking 20 years of human life．This has shown on all sorts of animals，even Labradors （a kind of dog）．" The scientists are also studying fruit flies，which share 60 percent of human genes and age in a similar manner，and mice．
They have already made the healthy lifespan （平均壽命） longer in both flies and mice by using drug treatments and a balanced diet．It is hoped that this combination will also work to extend human life．Dr．Piper said，"If we discover the genes involved with ageing，we should be able to delay ageing itself．This is what we've found．"
He added that the field of research into extending life is only a decade old，and so remains"in theory"．It is their special approach to treating all agerelated diseases caused by the"disease" of ageing itself that sets their research apart．
（1）The author writes this text in order to．
A．encourage people to eat as little as possible
B．tell people how harmful food is to their health
C．introduce an ongoing research on delaying ageing
D．show how similar mice and humans are to each other

2．Western artist R．V． （Ron） Jahns creates his unique western wildlife paintings by tapping into （利用） his vast experience of true life．He has rich western experiences out in the mountains in the great Northwest．
Ron paints from the heart and his experience as a cowboy in the west．He has a particular passion for the mountains from Eastern Oregon to Alaska and draws from his many years of mountain adventures as inspiration for his western paintings．Born and raised on a farm，this cowboy artist is well knowledgeable with the subjects of his western art．Ron struggles for historical accuracy in his western cowboy paintings when an artist gives a false description of the facts about cowboys in the west!

3．I'm walking along a river bed in California．The future stretched out ahead，in the valley，hills and mountains．The past is there too，but today I prefer to walk forward：to live"in the now"，and truly see all the good things in the world．Light clouds float high in the bright blue sky，and the sunlight shines off the house in the distance．People ride bicycles on the bike path that follows the river．They talk and laugh together．What a beautiful and peaceful scene it makes!
My heart is suddenly full of joy as I remember it is New Year's Day．A day to start a fresh and to feel gratitude for the gift of life God has given me．I pass by a man holding his son，one or two years old，whose face is a study in pure joy and wonder，as he looks out over the green hills and towering mountains．Tears gather in my eyes with the sweetness of this simple thought．A man sits gazing into the distance．In this lonely scene，I'm reminded of other days in the past when sadness and hopelessness were my only companions．I say a silent prayer for him，and thanks to God．Then I walk on．
A young couple crouch （蹲） next to a bicycle that has dropped its chain．As they look up，I smile and say "Happy New Year"．They smile and wish me the same．It is a simple thing，but for a moment we have become one with the world and a sudden joy takes my breath away．An old woman leans on a fence post．She doesn't seem either happy or sad，just gazes into the past，or maybe the future．A feeling of timeless peace flows through me and all fear of what the future may bring disappears．I thank her with my thoughts，and move on．
I walk by a stand of young trees．A loud burst of cheerful chirping （唧唧叫） from the little woods，and I can't help but laugh out loud．As I reach home，I say another thanks to God for the gift "now"．It has taken a long time to find it，and although I can't keep it with me all of the time，I know how to open the door again．I know whatever the New Year will bring，there will be joy and enough love of "now" to help me through the hard times we all must face．
Happy New Year!
