Task 3: Gap filling 答案请参考课本答案请参考课本 _ 课文翻译请参考下文：课文翻译请参考下文： 黑脉金斑蝶的旅程 许多动物都会在每年的特定时间从一个地方迁移到另一个地方。这种一年一度的行为叫做“迁 徙”。它们为了觅食、寻找

19、伴侣或温暖的环境而迁徙。自然界中最壮观的迁徙之一是北美洲黑脉金 斑蝶的迁徙。 每年秋天， 数百万这种翅膀橙黑相间的美丽昆虫都会开始漫长而艰辛的旅程。 它们总是设法完 成大约 4000 公里的南行之旅，成功到达加利福尼亚或墨西哥。然而，直到最近人们才明白它们是 如何做到的。 一支由伊莱 史莱泽曼教授领导的来自华盛顿大学的科学家团队现已找到了答案。他们发现， 黑脉金斑蝶可以判断时间， 并能用眼睛来测量太阳的位置。 这两条信息一天中的时间和太阳在 天空中的位置让黑脉金斑蝶判定前进方向，最终成功抵达过冬的地点。 黑脉金斑蝶这一惊人能力的奥秘被揭晓时， 这一生物正处于水深火热的生存状态中。 其数量在 近几年内减少了百分之九十之多。可悲的是，人类活动是黑脉金斑蝶数量下降的主要原因。在黑脉 金斑蝶生存的许多地方，人们正破坏着那里的自然环境。他们砍伐树木，他们所用的化学制剂杀死 了黑脉金斑蝶幼虫食用的植物。 不过， 对黑脉金斑蝶行为的研究也使得人们对这种生物有了更多的认识。 人们已经在共同努力， 记录它的迁徙，并确保它有足够的食物。如果这些努力产生效果，黑脉金斑蝶的数量在未来有可能 会再次回升。 我们对这个可爱的生物了解越多， 它们在自然界中得以长久生存并保持其地位的可能 性就越大。
