 　　Eruptions of Mount Saint Helens

　　On March 27, the US Government scientists made a decision after they predicted the eruption of Mount Saint Helens. They telephoned all state and local officials in the area and told them that a serious eruption was possible at any time. Roads were closed to every one except scientists and forest keepers struggled to keep curious visitors away from the mountain.

　　Shortly afternoon on March 27, Mount Saint Helens erupted for the first time in 123 years.

　　People living north of the mountain heard a loud boom that shook their windows, and airline pilots flying near the volcano soon afterwards described a thick black column of ash and steam shooting more than 2,100 meters into the sky.

　　Later, scientists found that the explosion had made a new crater (大坑) in the top of the mountain, not far from the old crater. The north side of the peak now had a huge bulge (凸出部分)where rock and ice had been pushed out by the eruption.

　　A second eruption shook the mountain on March 28. It, too, sent up a column of black ash high into the sky. By March 29, scientists flying over the mountain saw that a second crater formed about 9 meters from the first one. Strange blue flames flickered (闪烁) inside the crater and sometimes jumped from one crater to the other.

　　By April the mountain had erupted several more times and the snow on the north slope of the peak was black with ash. Ash carried by the wind had fallen on towns as far as 240 kilometers away from Mount Saint Helens.

　　During the first week of April, Mount Saint Helens gave scientists something new to worry about: harmonic tremors (振动) recorded by scientists showed a big eruption would happen. All during April and into May Mount Saint Helens continued to shudder ( 振动 ) and shoot out ash. By April 8, two craters had merged to from a vast hole nearly a half of a kilometer wide and 250 meters deep.

　　Scientists' main worry during this time was the growing bulge of rock and ice on. the north face of the mountain. By May 7 scientists feared the worst. Their warnings led Washington Governor to set up safety zones around the mountain. The inner "red" zone was open to scientists only. The outer "blue" zone was open only to people who got special permits. But in spite of these warnings, some people got past the road barriers and risked their lives trying to get close to the volcano.

　　试题解析

　　1.A。题干：美国科学家预测圣•海伦斯火山很快会爆发。利用题干的关键进行定位，由第一段中“On March 27，the US Government scientists made a decision after they predicted the eruption of Mount Saint Helens.”和第二段中“Shortly afternoon on March 27，Mount Saint Helens erupted for the first time in l23 years.”可知，美国科学家预测圣•海伦斯火山很快会爆发。

　　2.B。题干：飞行员在高空2 100多米的地方可以看见一股黑色的灰烬和蒸汽从火山口直冲上天。利用题目顺序与段落顺序一致的原则和题干关键词可以定位到第二段中“…and airline pilots flying near the volcano soon afterwards described a thick black column ofash and steam shooting more than 2，100 meters into the sky”，可知是飞行员看见“a thick black column ofash and steam shooting more than 2，l00 meters into the sky”，而不是飞行员在2 100米的高度。

　　3.B。题干：一个新的火山口在第二次爆发后形成了，位于前一个火山口的南边。利用题目顺序与段落顺序一致的原则和题干关键词可以定位，由第二段第一句话“Shortly afternoon on March 27，Mount Saint Helens erupted for the first time in 123 years.”和第三段中“Later，scientists found that the explosion had made a new crater(大坑)in the top of the mountain，not far from the old crateE”可知，the new crater是在the first eruption时形成的。

　　4.A。题干：四月第一周在圣•海伦斯火山区做的地震记录警惕科学家们关注新一轮的火山爆发。利用题目顺序与段落顺序一致的原则和题干关键词可以定位到第六段第一句话，可知“During the first week ofApril，Mount Saint Helens gave scientists something new to worry about：harmonic tremors(震动)recorded by scientists showed a big eruption would happen.”是正确的。quake也是“震动”的意思。

　　5.C。题干：两名科学家在圣•海伦斯火山第二次爆发中丢了性命。利用题目顺序与段落顺序一致的原则和题干关键词可以定位到文章最后一段，提到一些人冒着生命危险去接近火山，并没有提到有人死亡。

　　6.B。题干：圣•海伦斯火山的爆发多数发生在五月初。利用题目顺序与段落顺序一致的原则和题干关键词可以定位到文章最后一段“By May 7 scientists feared the worst”，由此可知，只是科学家害怕会发生the dreadful eruptions，但事实上并没有发生。

　　7.c。题干：圣•海伦斯火山的爆发吸引了大批的外国游客。利用题目顺序与段落顺序——致的原则和题干关键词可以定位到文章最后一段，提到“some people got past the road barriers and risked their lives Wing to get close to the volcano”，可知一些人越过路上的障碍，冒着生命危险去接近火山，但并没提到吸引了外国的游客。
