阅读理解Every year landslides cause 25 to 50 deaths and $2 billion in damage in the United States. And in December, a single event killed more than 2000 people in the Philippines. Sending workers to stabilize mountainsides using steel bars can help a lot, but it introduces new difficulties because of dust and loosen heavy, dangerous debris from the work. “It’s a quite dangerous job,” says Giorgio Pezzuto of D’ Appolonia, working with eight other panies. Now there may be an answer: a three-ton robot called Roboclimber.“The idea is to operate a machine far away that can do the stabilizing job without a human being near,”says Pezzuto, manager for the project, which is supported by a European organization. Engineers say that the machine will be faster and cheaper than manual labor. The robot, a large radio-controlled four-legged spider, has cost at least $2 million so far. It should be able to climb mountainsides, drill holes and insert steel bars there. Testing should begin in May.1.The underlined word “event” refers to_____A.earthquakeB.debrisC.dustD.landslide2.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 dangerous jobC.to show people how to use a new robotD.to introduce a new robot that can be used to stabilize mountainsides3.What does the robot look like?A.human beingB.spiderC.steel barD.a drill4.A landslides cause _____________in damage in the United States Every year .A.25 to 50 deathsB.more than 2000 people diedC.$2 billionD.both A and C5.The biggest advantage of this product is that____A.it will be faster and cheaper than manual laborB.it can climb mountainsides, drill holes and insert steel bars there.C.it can do the stabilizing job without human beings nearD.it is like a spider
