thought that they would never see the sunlight again and would spend the rest of their “lives” guarding and protecting the first Chinese emperor,Qin Shi Huang,who died in 210 BC.But things got better off these clay (陶土的) soldiers.Ever since they were discovered in Xi’an in 1974,by a group of farmers;they’ve been able to see the bigger world—traveling from one museum to the next.They are now on display in New York at Discovery Times Square,reported The New York Times.However,the story doesn’t end here.The roughly 2,000 soldiers found so far are estimated(估计) to be only one quarter of the total number.Moreover,scientists haven’t yet dared to touch the central tomb,which is believed to contain the body of the emperor himself.“Partly it’s out of respect for the elders,” explained Kristin Romey,consultant(顾问) for the exhibition.“But they also realize that nobody in the world right now has the technology to properly go in and excavate(挖掘) it.”This is true.According to ancient writings,the emperor’s tomb is circled by rivers of liquid mercury(水银) which is highly poisonous but can keep the body in good condition.Studies of the soil around the tomb also found a large amount of mercury.This makes exploring the tomb very dangerous.The other reason that scientists have been hesitating is that they are afraid of the damage they might cause by opening the tomb.“When we began excavating ‘the soldiers’,the minute they were exposed to air and sunlight,the pigment(颜料) just flaked off (剥落),” Romey told the Fox News.But he believes that the solution will come when science advances.Perhaps a visual robot can be sent into the tomb first to investigate and help figure out the best way to protect it.In the end,scientists and historians must weigh their desire to know against the damage their digging might cause.“Archaeology,ultimately (最终),is a destructive science,” Romey said.“You have to destroy stuff in order to learn about it.”1.What is the point of the article?A.To tell about the mysteries of Qin Shi Huang’s tomb.B.To analyze why archaeology is a destructive science.C.To introduce the Terracotta Warriors exhibition in New York.D.To explain the risks
