1.1 Warming Up通过对火山爆发示意图的讨论激活学生了解与本单元话题相关的背景知识,而后通过讨论人类应对自然灾害的措施引发学生对本单元话题的思考,激发学生的求知欲,为随后进行的听、说、读、写打下基础。

高中英语 Unit 5《The Power of nature-火山分布》文字素材 新人教版选修6
火山分布世界上有很多火山,在过去400多年里,爆发过的活火山就有500多座。
火山的数量虽多,但它的分布却是很有规律的。
人们把火山分为四带:环太平洋火山带、大西洋火山带、地中海火山带和东非火山带。
太平洋火山带包括东西两岸,像我国的台湾就在这条火山带上。
号称“火山之国”的萨尔瓦多也在这条火山带上,世界上最高的活火山-智利的尤耶亚科火山,海拔6723米;最高的死火山-智利的阿空加瓜火山,海拔6964米,也都在这个带上。
大西洋火山带中最引人注目的海底火山爆发和随之而来的火山岛的形成。
在那里,有时候你会看到海底火山喷发的奇特景象,数天的时间里,原来一片汪洋处就能冒出一座岛屿。
由于新形成的火山岛物质还比较疏松,抵抗不住海浪的冲击,所以经常会像变魔术一般又突然消失了。
地中海火山带以火山活动频繁而著称,举世闻名的维苏威火山就在这条火山带上。
这条带上的很多火山至今仍然活动着,如位于西西里岛上的埃特纳火山,从公元前6千多年一直到今天从未停止过喷发。
非洲大陆因受到两侧的拉扯力而形成断层,叫作东非大裂谷,这里也是火山活动十分活跃的地方。
大裂谷两侧,耸立着一座座火山,死火山至今仍有水汽喷出,温泉涌流,活火山更是热气腾腾,烟雾缭绕。
两个世界闻名的火山奇观就在这里:一是第二大破火山口-恩戈罗恩戈罗火山口,一是尼拉贡戈火山的熔岩湖。
非洲第一高峰-乞力马扎罗山,第二高峰-肯尼亚山,这两座死火山的山顶终年覆盖着白雪,十分美丽。
中国的火山,约660座,其中绝大部分是死火山。
活火山和休眠火山主要分布在台湾省、昆仑山区、黑龙江省、长白山和云南腾冲等地。
黑龙江和吉林共有230多座,其中著名的有五大连池和白头山。
内蒙古是我国火山数量最多的地区,共有270多座,我国最大的,包含有100多座火山的火山群,就分布在这里,其中达里火山群有多达56座火山。
台湾省正好位于环太平洋火山带中,是我国火山活动最为剧烈的地方。
澎湖列岛、火烧岛、钓鱼岛等都是海底火山喷发而成的火山岛。
