6、夫”的称号。主要行为活动为钻进牛粪里的虫类，可以将粪便滚动成球状，推行向前。世界上有2万多种蜣螂，分布在南极洲以外的任何一块大陆。最著名的蜣螂（圣甲虫）生活在埃及，有 12.5厘米长。世界上最大的蜣螂是10厘米长的巨蜣螂。典型篇章A Remarkable Beetle 一种值得注意的甲虫相关背景知识：进食规律在非洲大草原上，当雨季雨后的第四天夜里，成千上万只蜣螂就会从地面钻出来。大雨过后，大象贪婪地享用着新生的植物，可是消化系统难以承受这突然增大的负荷，不少吞下去的食物又奉还到地面上。巨蜣螂是蜣螂中体形最大的一种，它的食物来源主要依靠大象的粪便。每天，大象们在平原上留下数百吨象粪，后面跟随着蜣

7、螂大军。一部分象粪被埋入地下，蜣螂的劳动使得土地肥活起来。这是一个循环往复的过程，巨蜣螂在其中担负着重要的角色。典型篇章A Remarkable Beetle 一种值得注意的甲虫相关背景知识：生物链中意义：因为能加速使粪便转变为其他生物能利用的物质的过程，所以对人类有益。农业用途蜣螂可以清理动物的粪便，抑制其他以粪便为食的害虫，以及减少排放的温室气体。在澳大利亚，原有的蜣螂品种只喜爱食用小粒的粪便如袋鼠粪，而不喜欢外来的牛、羊的粪便。从 19651985 年，澳大利亚联邦科学与工业研究组织在 George Bornemissza 博士领导下，开始了澳大利亚蜣螂计划，成功的从世界各地引进 23

8、个品种的蜣螂，其中显著的品种有 Onthophagus gazella 和 Euoniticellus intermedius。结果改善了澳大利亚的牧场的粪便堆积问题，同时减少了约 90%有害的丛林飞蝇。典型篇章例题讲解Question：Do the following statements reflect the claims of the writer in Reading Passage 1?In boxes 1-5 on your answer sheet write YES if the statement reflects the claims of the writer NO i
