The Monarch's Journey
Many animals move from one place to another at certain times of the year．This annual① movement is called migration②．They migrate③ to find food，seek④ a partner，or in search of⑤ warmer weather．One of the most wonderful migrations in nature is that of the North American monarch butterfly[1]．
[1]此处that是指示代词，指代前面的one of the most wonderful migrations。
Every autumn，millions of⑦these beautiful insects with fine black and orange wings begin a long and difficult journey．Somehow⑧ they manage to travel⑨ around 4，000 kilometres south and find their way to California or Mexico．However，until recently no one knew how they did this[2]．
[2]until...no...是“not...until...”的变式，意为“直到……才……”。
A team of scientists led by Professor⑩ Eli Shlizerman at the University of Washington[3] has now found the answer．They have found out that the monarch is able to tell the time of day．It uses its eyes to measure the position of the sun．These two pieces of information—the time of day and the point where the sun is in the sky[4]—allow the butterfly to determine the way to go．Eventually ，it manages to reach the places where it will spend the winter．
[3]led by...是过去分词短语，作A team of scientists的定语。
[4]关系副词where引导定语从句，修饰先行词the point，where在从句中作地点状语。
The solution to the mystery of the monarch's amazing ability comes at a time when it is in serious trouble [5]．Its population has crashed by as much as 90 per cent in the last few years ．Sadly，human activity is the main reason why the number of monarch butterflies is falling[6]．In many of the places where the butterfly can be found[7]，people are destroying the natural environment．They cut down trees and use chemicals that kill the plants that monarch caterpillars eat[8]．
[5]关系副词when引导定语从句，修饰先行词a time，when在从句中作时间状语。
[6]关系副词why引导定语从句，修饰先行词the main reason，why在从句中作原因状语。
[7]关系副词where引导定语从句，修饰先行词the places，where在从句中作地点状语。
[8]that kill the plants that monarch caterpillars eat是that引导的定语从句，修饰先行词chemicals，其中that monarch caterpillars eat为定语从句，修饰先行词the plants。
The research on the monarch's behaviour has however led to a greater awareness of this creature ．People have been working[9] together to record its migration and make sure that there are enough plants for it to feed on ．If this works ，there may come a time when the number of monarch butterflies increases once again．The more we know about this lovely creature，the greater the chance it will survive and keep its place in the natural world for a long time to come．[10]
[9]have been working是现在完成进行时，表示从过去某时开始一直延续到现在并有可能继续下去的动作。
[10]该句是“the＋比较级，the＋比较级”结构，意为“越……就越……”。
黑脉金斑蝶的旅程
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”。它们为了觅食、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。
每年秋天，数百万只这种翅膀橙黑相间的美丽昆虫都会开启漫长且艰辛的旅程。它们总是能够完成约4 000公里的南行旅程，成功到达(美国)加利福尼亚州或墨西哥。然而，直到最近人们才明白它们是如何做到的。
一支由伊莱·史利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。
黑脉金斑蝶这一惊人能力的奥秘被揭开时，这一生物正处于水深火热的生存状态中。其数量在近年内减少了百分之九十之多。不幸的是，人类活动是造成其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了解。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再次回升。我们对这种迷人的生物了解越多，它们在自然界中得以长久生存并保持其位置的可能性就越大。
