A piece of work reported in this week's Nature by Darren Baker of the MayoClinic,in Minnesota,though,describes an extraordinary result that points to a way the process might be ameliorated.
Particular versious of certain genes have been shown to ptolong life,but is no help to those who do not have then.求英语高手帮忙分析一下句子结构,
第一句主干为：A piece of work describes an extraordinary result(一项研究表明了一种特殊的结果).reported in this weeks Nature为后置定语,修饰work；by ...in Minnesota修饰work,是介绍作者；though是连词；that ...ameliorated为result 后的名词性从句；第二句have been是个现在完成时句子,后面这句貌似不对,没有主语呢.
