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 there was ever a single
event
killed more than 200 people in the Philippines. Sending workers to stabilize mountainsides using steel bars and cement(水泥)can help prevent disasters, but it introduces new difficulties. Shaking drills produce harmful dust and loosen heavy, dangerous debris(岩屑). "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, the 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, 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 stability. Testing should begin in May.
The underlined word "event"(Paragraph 1)refers to______.
选项
A、landslide
B、machine
C、earthquake
D、flood
答案
A
解析
词语释义题。本文主要是谈landslide,一开始就谈论land—slide的危害,并且举例子说在菲律宾一次就死了200多人。所以这里的event指代landslide。
