B
The Young Can't Wait
By Severn Cullies Suzuki
When you are little, it's not hard to believe you can change the world. I remember my enthusiasm when, at the age of 12, I addressed the delegates at the Rio Earth Summit. “I am only a child,” I told them. “Yet I know that if all the money spent on war was spent on ending poverty(贫困) and finding environmental answers, what a wonderful place this would be. In school you teach us not to fight with others, to work things out, to respect others, to clean up our mess, not to hurt other creatures, to share, not to be greedy. Then why do you go out and do the thing you tell us not to do? You grown-ups say you love us, but I challenge you, please, to make your actions reflect(反省) your words.”
I spoke for six minutes and received a standing ovation. Some of the delegates even cried. I thought that maybe I had reached some of them, that my speech might actually spur(刺激) action. Now, a decade(十年) from Rio, after I've sat through many more conferences, I'm not sure what has been accomplished. My confidence in the people in power and in the power of an individual's voice to reach them has been deeply shaken.
When I was little, the world was simple. But as a young adult, I'm learning that as we have to make choices—education, career, lifestyle—life gets more and more complicated. We are beginning to feel pressure to produce and be successful. We are taught that economic growth is progress, but we aren't taught how to pursue a happy, healthy or sustainable way of living. And we are learning that what we wanted for the future when we were 12 was idealistic and naive.
Today I'm no longer a child, but I'm worried about what kind of environment my children will grow up in. I know change is possible, because I am changing, still figuring out what I think. I am still deciding how to live my life. The challenges are great, but if we accept individual responsibility and make sustainable choices, we will rise to the challenges, and we will become part of the positive tide of change.

A.end poverty and make school beautiful
B.find environmental answers and keep the words that they always told themselves

Ants have a reputation for strength,organization and teamwork.But researchers have now discovered that a key secret to the success of ants is their ability to identify the importance of age in the work place.
A study of Gentral American leaf-cutter ants has shown that the younger and stronger members are give the toughest job of cutting therough the leaves they harvest.Their sharp youn teeth do this job effectively,but as they get older their teeth become relatively worn and blunt.
But rather than being retired or abandoned by the group,the ageing ants are given a new role more suyted to their physical abilities.They become carriers and teansport the leaves back to the kingdom where they are harvested for food.
The findings by researchers from the University of Oregon and the Oregong State University support previous research showin the survival of a leaf-cutter kingdom depends on the efficiency(效率)of is workers.
“Cuting leaves is hard work,”said Dr.Robert Schofield,who led the research team.“Much of the cutting is done with a V-shaped blade(刀片)between teeth on their jaws.This blade starts out as sharp as the sharpest razor blade that humans have developed.”But over rime the teeth become blunter and the cutting job slows down.The team estimated that,because of this age-related wear,a colony(蚁群)spent twice the energy cutting leaves than it would if all the ants had sharp blades.Its findings support the idea that wear and break can be significant problems for insects as well as largre animals.
Like humans,leaf-cuttre ant recognize that older members of the group can still make a worhwhile contribution to society.“This study shows an advantage of social living that we are familiar with,”said Dr.Schofield.
