三、七选五
In 1980 in Washington, after 123 years of hibernation, Mount St. Helens erupted. ①_____. The eruption released a lot of hot ash, gas, steam and rocks that moved down giant trees up to 15 miles away.
②_____. Some, like Mount St. Helens, explode. Volcanic eruptions are so powerful. They can shoot particles 20 miles up, and cause massive landslides. ③_____, which destroy everything in the path. Explosive volcanoes cause most of the volcano-related fatalities(死亡). Volcanoes, like Mauna Loa in Hawaii, are effusive(大量喷发的). Rather than a violent explosion, lava pours or flows out.

三、答案：①-⑤ FCEGB
解析：①上文提到“1980年在华盛顿，休眠了123年后，圣海伦斯火山爆发了”，F项“这次爆发在几分钟内摧毁了230平方英里的森林”可承接上文。
②下文提到圣海伦斯火山是爆发，莫纳罗亚火山是喷发。由此可知，火山爆发的方式不同，所以用C项引出下文。
③根据下文的“毁坏了路上的一切”可知，E项符合语境。
④上文提到“岩浆流出来”，G项“流动的岩浆摧毁它所触及的一切，包括农场、房屋和道路”可承接上文。
⑤根据下文的“它们还创造了山脉、岛屿，最后是肥沃的土地”可知，B项符合语境。
四、答案：less ; molten ; eruption ; when ; passing; caused ; even ; absolutely ; Having studied; beauty
解析：①解析:名词damage不可数,后面的连词than和less构成比较级句型。
②解析:理解句意可知,这些岩石已经融化了,而不是正在融化,故用molten。
③解析:定冠词后面应该跟名词。
④解析:根据句意可知,“我”的床开始摇晃的时候“我”正在熟睡中,故时间状语从句的连词用when。
⑤解析:介词like后面跟动名词作宾语, a train是动名词的逻辑主语。
⑥解析:过去分词短语作后置定语,表示被动。
⑦解析:even though“即使”引导让步状语从句。
⑧解析:修饰形容词时要用副词。
⑨解析:本题用分词短语作状语,分词短语中的时间状语for many years表明study的动作在谓语动作之前持续了好多年,故用现在分词的完成式作状语。
⑩解析:形容词性物主代词后面应该跟名词。
