Ⅱ.阅读理解【主题:人与社会　科学】
Researchers who examined DNA from famous German musician Ludwig van Beethoven have found something new about his health.
They found that he had a risk for liver(肝脏) disease.The DNA also showed that Beethoven caught the hepatitis B virus(乙肝病毒) in the last months of his life.The virus hurts the liver.The findings suggest Beethoven’s liver problems were enough to cause the liver failure widely believed to have killed him.The musician was also believed to have been a heavy drinker,which can influence the liver.
The musician himself wrote that he wanted doctors to study his health problems after he died.Axel Schmidt is a researcher who helped lead the research.He said that Beethoven’s sicknesses had“sometimes prevented his creative work”.Schmidt added that for many doctors,“it has always been a mystery”what exactly killed him.
Since his death,scientists have long tried to piece together Beethoven’s medical history.And they have offered many explanations for his many health conditions.But new examination technology and methods now make it possible to revisit(再次讨论) health and death information by studying ancient DNA.The DNA was collected from hair cut from Beethoven’s head.
Getting enough genetic(遗传的) material was difficult because DNA in hair gets cut up into very small pieces.But finally,after using up almost 3 metres of Beethoven’s hair,the team finished it.
The question of what caused Beethoven’s hearing loss remains unanswered,said Ohio State University’s Dr.Cooper.He said that the mystery might continue forever because DNA can not show us everything about our health.However,Cooper added that the mystery is part of what makes Beethoven so interesting and popular.“The fact that we can’t know is OK,”he said.
