2、surprised to find the earth warm under their feet.Suddenly they heard a noise deep in the earth and a small hole appeared in their field.In the afternoon there was a sudden loud noise and stones were thrown high in the air.The peasants ran away from the field and turned back to watch.They saw the birth of a volcano.Large quantities of stones and lava broke out and a little hill began to form.By evening this hill was 100 feet high and hot ashes were falling on the village.At night the strong ligh

6、 stopped.答案:D解析:句意理解题。帕里库廷火山的“睡眠”意指其“停止喷发了”。BAn annoying problem for humans,who like to boast(夸耀) about all the distant planets and moons we have explored,is that weve never taken a good look right under our noses.The inside of the earth is relatively close,but how can we get there?The deepest oil well enters only six miles into the crust(地壳) (the center of the earth is about 4,000 miles deep).Russian scientists dug the deepest hole in Siberia,but bottomed out at about 7.5 miles below the surfac

7、e.The Mohole project,a U.S.plan in the 1950s,called for drilling a hole 25 miles down to the boundary(分界线) between the hard rocks of the crust and the soft mantle(地幔).Sadly the project involved government supporting.It gets harder and harder to drill deep into the earth because rocks get softer and softer.Hard but easily broken at the surface,rocks become plastic(可塑的) at depth,and the pressure caused by the weight of the overlaying crustabout 52,800 pounds per square inch at a depth of ten miles

8、,makes further drilling impossible. What little we know about the inside of the earth comes from indirect evidence,such as the analysis of earthquakes.So maybe its time for a thorough new method to explore the earths inside.Scientist David Stevenson says we should forget about drilling holes.Instead,we should open a crack(裂缝).Stevenson suggests digging a crack about a half mile long,a yard wide,and a half mile deep with an explosion on the scale of a nuclear bomb.Next,hed pour a few hundred thou

9、sand tons of molten(熔化的) iron into the crack,along with a robot.The iron,thicker than the surrounding crust,would move downward at about 16 feet per second,carrying the robot with it and opening the crack deeper and deeper.The iron mass would drop for about a week and 2,000 miles to the outer edge of the earth core,the robot sending out data to the surface.Stevenson compares his idea to space exploration.“Were going somewhere we havent been before,” he says.“In all possibility,there will be surprises.”This idea can probably be put in the drawer marked with“Isnt Going to Happen”.The robot would have to survive temperatures that would melt pretty much anything.But Stevensons idea may inspire a new look at an old problem.Great things can come from what seems like impossible ideas.5Going inside the earth is than going into space.A.more interesting
