Every year landslides {滑坡} cause 25 to 50 deaths and $1.5 billion in damage in the United States.They account for 15 percent of the deaths from natural disasters in Europe.And in December, a single event killed more than 200 people in the Philippines.Sending workers to stabilize (加固) mountainsides using steel bars and cement (水泥) can help prevent disaster, but it introduces new difficulties.Shaking drills produce harmful dust and loosen heavy, dangerous debris (米屑).It's quite a risky job, says Giorgio Pezzuto of D'Appolonia, an engineering company in Italy.D'Appolonia, working with eight other companies, may have an answer: a three-ton robot called Roboclimber.The idea is to operate a machine far away that can drill without a human being on board,' says Pezzuto, manager for the project, which is supported by the European Commission.Engineers claim that the machine will be faster and cheaper than manual labor.The robot, a large radio-controlled four-legged mechanical spider (蜘蛛), has cost at least $2 million so far.The final product should be able to climb unstable mountainsides, drill holes, insert bars and cement, and collect data on the slope' s stability.Testing should begin in May.1.The underlined word event (in Paragraph l) refers to ___.A.landslideB.machineC.earthquakeD.flood2.The purpose in writing this text is ___..A.to tell people how serious the damage caused by landslides isB.to tell people that sending workers to stabilize mountainsides is a risky jobC.to introduce a product that can be used to stabilize mountainsidesD.to show people how to use a new product3.What does the robot look like?

ACBD解析1.本文主要谈landslide,因此根据行文,event指代landslide。2.本文作者的意图是介绍一种用于滑坡抢险的新产品。3.读第二段The robot, a large radio-controlled four-legged mechanical spider (蜘蛛)及整个语篇可得出此结论。4.从第二段的The idea is to operate a machine far away that can drill without a human being on board一句以及第一段讲述滑坡人工抢险的危险,可知这种产品无人操作是其最大优点。
