This annual movement is called migration. They migrate to find food， seek a partner， or in search of warmer weather. One of the most wonderful migrations in nature1 is that of the North American monarch butterfly. 许多动物都会在每年的特定时间从一处迁移到另一处。这种一年一度的行为叫作“迁徙”。动物为了觅食、寻找配偶或温暖的环境而迁徙。自然界最为壮观的迁徙之一就是北美洲黑脉金斑蝶的迁徙。 Every autumn2 ， millions of these beautiful insects with fine black and orange wings3 begin a long and difficult journey. Somehow they manage to travel around 4，000 kilometres south4 and find their way to California or Mexico5 .

These two pieces of information—the time of day and the point where10 the sun is in the sky—allow the butterfly to determine the way to go11 . Eventually， it manages to reach the places where12 it will spend the winter. 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，并能用眼睛测量太阳的位置。这两条信息———一天中的时刻和太阳在天空中的位置———让黑脉金斑蝶能够判定前进方向，最终成功抵达过冬的地点。 The solution to the mystery of the monarch's amazing ability comes at a time when13 it is in serious trouble. Its population has crashed by as much as 90 per cent in the last few years. Sadly， human activity is the main reason why14 the number of monarch butterflies is ... ...
