The plan, brokered by Kofi Annan, calls for a UN-monitored end to the fighting, the pull-out of government troops from opposition cities and humanitarian access.
这项方案是科菲·安南从中斡旋的,呼吁在联合国的监督下结束战争,要求政府军从反对派城市撤出,并允许人道主义援助进入。
The discovery of eight fossilised foot bones in Ethiopia 3.4 million years old has given scientists a rare insight into the evolution of humans and their ability to walk. Jonathan Amos reports.
8个3.4百万年前的脚骨化石在埃塞俄比亚被发掘,这给科学家在研究人类进化和直立行走能力上提供难得的思路。Jonathan Amos报道。
The eight small bones of a right foot unearthed in the Afar region of central Ethiopia are an important discovery. Scientists know of one human ancestor that lived in this location 3.4 million years ago: the creature famously dubbed "Lucy", whose skeleton displayed a clear preference to walk upright - a key marker of what it is to be human. But researchers tell the journal Nature these new bones are not from Lucy. They are more primitive with a big toe that could grasp branches in a tree. Nonetheless, they too show an ability to walk upright on occasions albeit with a different gait.
在埃塞俄比亚中部阿法尔地区发掘的这八个右脚的小骨头是个重大发现,科学家知道3.4百万年前,人类的一个祖先就在这里生活,人们给这种生物取名为“露西”,从这类动物的骨骼来看,很显然它们更喜欢直立行走,这也是成为人类的一个重要标志。但研究者对《科学》杂志表示,这些新发掘的骨头并不是“露西”的。这种生物更原始,有一个脚趾很大,可以在树上抓住树枝。而且,这些动物还可以不同的步态直立行走。
