The Mnarch's① JurneyMany animals mve frm ne place t anther at certain times f the year．This annual② mvement is called migratin③．They migrate④ t find fd，seek⑤ a partner，r in search f ⑥ warmer weather．One f the mst wnderful migratins in nature is that f the Nrth American mnarch butterfly[1]．
[1]此处that是指示代词，指代前面的One f the mst wnderful migratins。
Every autumn，millins f ⑦ these beautiful insects with fine black and range wings begin a lng and difficult jurney．Smehw⑧ they manage t travel⑨ arund 4，000 kilmetres suth and find their way t Califrnia r Mexic．Hwever，until recently n ne knew hw they did this[2]．
[2]是“”的变式，意为“直到……才……”。
A team f scientists led by Prfessr⑩ Eli Shlizerman at the University f Washingtn[3] has nw fund the answer．They have fund ut⑪ that the mnarch is able t tell⑫ the time f day．It uses its eyes t measure⑬ the psitin⑭ f the sun．These tw pieces f infrmatin—the time f day and the pint where the sun is in the sky[4]—allw the butterfly t⑮ determine⑯ the way t g．Eventually⑰，it manages t reach the places where it will spend the winter．
[3]led by...是过去分词短语，作A team f scientists的定语。[4]关系副词where引导定语从句，修饰先行词the pint，where在从句中作地点状语。
The slutin⑱ t the mystery⑲ f the mnarch's amazing⑳ ability cmes at a time when it is in serius truble㉑[5]．Its ppulatin has crashed㉒ by as much as 90 per cent㉓ in the last few years㉔．Sadly，human activity㉕ is the main reasn why the number f ㉖ mnarch butterflies is falling[6]．In many f the places where the butterfly can be fund[7]，peple are destrying㉗ the natural envirnment．They cut dwn㉘trees and use chemicals㉙ that kill the plants that mnarch caterpillars㉚eat[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 reasn，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 mnarch caterpillars eat是that引导的定语从句，修饰先行词chemicals，其中that mnarch caterpillars eat为定语从句，修饰先行词the plants。
The research n the mnarch's behaviur has hwever led t㉛ a greater awareness f this creature㉜．Peple have been wrking[9] tgether t recrd its migratin and make sure㉝ that there are enugh plants fr it t feed n㉞．If this wrks㉟，there may cme a time when the number f mnarch butterflies increases nce again．The mre we knw abut this lvely creature，the greater the chance it will survive㊱and keep its place㊲ in the natural wrld fr a lng time t cme．[10]
[9]have been wrking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。
