2、ng each year, and of those, seventy people die.

3、ghtning，” said Rocky Lopes, a disaster educator at the American Red Cross.“Thunder means that lightning is close enough to hit you at any time, so you should move indoors immediately and stay there until the storm has ended.

12、室外工作，有时在办公室里，有时(工作中)要用科学仪器，有时要会见当地百姓和旅游人士，我从来不感觉(工作)无聊。虽然我的工作偶尔也有危险，但是我并不在乎，因为危险能使我兴奋，使我感到有活力。然而，最重要的是，我的工作能帮助保护普通百姓免遭火山的威胁这是世界上最大的自然威力之一。20年前，作为一名火山学家，我被派到夏威夷火山观测站(HVO)工作。我的任务是收集有关基拉韦厄火山的数据资料，这是夏威夷最活跃的火山之一。收集和评估这些信息之后，我就帮助其他科学家一起预测熔岩接着将流向何处，流速是多少。我们的工作拯救了许多人的生命，因为住在熔岩流经之地的老百姓都可以得到离开家园的通知。遗憾的是，我们不可能
13、把他们的家搬离岩浆流经之路，因此，许多房屋被熔岩淹没，或者焚烧殆尽。当滚烫的岩石从火山喷发出来并撞回地面时，它所造成的损失比想象的要小些，这是因为在岩石下落的基拉韦厄火山顶附近无人居住。而像波浪一样顺着山坡缓缓流下的火山熔岩所造成的损失却大得多，这是因为火山岩浆所流经的地方，一切东西都被掩埋在熔岩下面了。然而火山喷发本身看起来的确是很壮观的，我永远也忘不了我第一次看见火山喷发时的情景。那是在我抵达夏威夷后的第二个星期。那天我辛辛苦苦地干了一整天，很早就上床睡觉了。我在熟睡中突然感到床铺在摇晃，接着我听到一阵奇怪的声音，就好像一列火车在我的窗外行驶一样。因为我在夏威夷曾经经历过多次地震，所以对此
14、我并不在意。我刚要再睡，突然我的卧室亮如白昼。我跑出房间，来到后花园，在那儿我能看见远处的基拉韦厄火山。在山的一边有火山喷发，红色发烫的岩浆像喷泉一样，朝天上喷射达几百米高。真是绝妙的奇景。就在这次火山喷发的第二天，我很幸运，能更近距离地观察它。我和另外两位科学家被驱车送上山，到最靠近这次火山喷口的地方才下车。早先从观测站(出发时)就带了一些特别的安全服，于是我们穿上安全服再走近火山口。我们三个人看上去就像宇航员一样，我们都穿着白色的防护服遮住全身，戴上了头盔和特别的手套，还穿了双大靴子。穿着这些衣服走起路来不容易，但我们还是缓缓往火山口的边缘走去，并且向下看到了红红的沸腾的中央。另外两人爬下
15、火山口去收集供日后研究用的岩浆，我是第一次经历这样的事，所以留在山顶上观察他们。,如今，我和当初从事这项工作时一样满怀热情。虽然我现在从事火山研究很多年了，但是我对火山的壮丽景色以及它们那潜在的巨大破坏力仍然感到惊愕不已。课文理解Task One：Fast Reading.The text mainly tells us about a volcanologists exciting job and his first sight of a volcano eruption.Read the passage and then write down the main idea for each
