them.Then，huge numbers of Native Americans began dying from smallpox (天花) infection.Fivehundredyearold documents record this tale，but now scientists say theyve found other evidence buried deep inside human cells.In a new study，Brendan OFallon and Lars FehrenSchmitz report evidence found in genes that the Native American population dropped by half after the arrival of Europeans.OFallon studies genes at ARUP Laboratories in Salt Lake City，while FehrenSchmitz is a scientist who studies humankind，at the University of Gttingen in Germany.Cells make up every part of the body.Deep inside almost every cell is a long，coiled molecule (盘绕颗粒) called DNA.Genes are parts of DNA that play important roles in determining ones life.Genes help determine a persons appearance，such as skin color and height，and also play a role in many things you cant see，like the chance of getting a disease.Genes change over time，and by following these changes scientists can learn about a persons ancestors.OFallon and FehrenSchmitz looked at genes in the mitochondria of cells.(Mitochondria are like factories that help cells use energy from food.) The scientists compared DNA from the remains of ancient Native Americans with DNA from living people descended (遗传) from Native Americans.The scientists studied patterns in the genes from the two groups and identified ways that the patterns changed over time.Using statistics，which includes useful mathematical tools for analyzing large amounts of data，the researchers were able to judge the size of the Native American population before and after the Europeans arrival.The comparison showed the number of native people reduced sharply after European settlers landed in the New World.Earlier genetic studies didnt have evidence of the Native American dieoff.Scientists involved in the new study say that theres now more data from ancient remains，so researchers can get a better idea of what happened.语篇解读基因承载了人类遗传密码，是随时间推移而不断变化的。通过对基因的分析和研究，人们可以解开很多秘密。1Brendan OFallon and Lars FehrenSchmitz work_.Aat the same universityBin the same countryCfor different purposesDto get the same result解析：细节理解题。根据第二段和第四段的内容，可知两位科学家并不在同一个国家，同一个大学工作，在研究基因时，也不是为了不同的目的，最后得出的是同一个结论，所以D项正确。答案：D2Genes help determine many things of a person EXCEPT_.Aa persons appearance Ba persons skin colorCa persons height Da persons success解析：细节
