But no one could say when. And no one expected the terrible strength of the eruption. Many people were surprised and unready. Harry R. Truman, 84, owned a small hotel in Mt St Helens. Scientists had asked people to move away because the volcano was being dangerous. But Harry Truman would not leave his home. Now it is covered with many feet of dirty ash. A small cross stands above the place where Harry probably died. Perhaps it is better that he did not see the destruction of Mt St Helens, the once beautiful lake, and the forests.

Perhaps Mt St Helens will erupt again. But this is all part of nature39。s stability D. it can drill without a human being on board 答案: D 解析: 細(xì)節(jié)理解題。由第二段倒數(shù)第三句 “ The robot, a large radio controlled four legged mechanical spider (蜘蛛 ), has cost at least $2 million so far.” 可知,這款機(jī)器人的外形像蜘蛛。結(jié)合上下文可知 , event 此處指的是發(fā)生在 12月的一次 landslide (滑坡 )。Appolonia, working with eight other panies, 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 slope39。s quite a risky job, ” says Giio Pezzuto of D39。 Ⅲ .閱讀理解 閱讀下面的短文,從每題所給的四個(gè)選項(xiàng) (A、 B、 C、 D)中,選出
