cold winter？ Step Three　Read for details Ⅰ．Read Para．1 carefully and do the following exercises． Decide if the following statements are True (T) or False (F)． 1．All animals migrate at the same time of the year．(　　) 2．Migration is the annual movement of animals from one place to another． (　　) 3．Animals only migrate to find food．(　　) 2．What body part does the monarch butterfly rely on to measure the sun's position？ A．Its antennae． B．Its legs． C．Its eyes． D．Its wings． 3．Which section is this article likely to appear in the newspaper？ A．Sports． B．Health． C．Hobby． D．Wildlife． The Monarch's Journey 　　Many animals move from one place to another at certain times of the year．This annual①movement② is called migration③．They migrate④ to find food，seek⑤ a partner，or in search of warmer weather．One of the most wonderful migrations in nature is that of the North American monarch butterfly⑥． ①annual adj．一年一度的，每年的 ②movement n．动作，活动 ③migration n．迁徙 ④migrate v．移栖，迁徙 ⑤seek v．寻找，寻求 ⑥monarch n．君主，国王 monarch butterfly 黑脉金斑蝶 　　Every autumn，millions of these beautiful insects with fine black and orange wings begin a long and difficult journey．Somehow⑦ they manage to travel around 4，000 kilometres south and find their way to California or Mexico．However，until recently no one knew how they did this． ⑦somehow adv．用某种方法；不知怎么地 [1]过去分词短语作后置定语。 [2]where引导的定语从句修饰先行词point。 　　A team of scientists led by Professor⑧ Eli Shlizerman at the University of Washington[1]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 measure⑨ the position⑩ of the sun．These two pieces of information—the time of day and the point where the sun is in the sky[2]—allow the butterfly to determine⑪ the way to go．Eventually⑫，it manages to reach the places where it will spend the winter． ⑧professor n．教授 ⑨measure v．量，测量 ⑩position n．位置 ⑪determine v．测定，确定 ⑫eventually adv．终于，最终 　　The solution⑬ to the mystery⑭ of the monarch's amazing⑮ ability comes at a time when it is in serious trouble．Its population has crashed⑯ by as much as 90 per cent⑰ in the last few years．Sadly，human activity is the main reason why the number of monarch butterflies is falling．In many of the places where the butterfly can be found，people are destroying⑱ the natural environment．They cut down trees and use chemicals⑲ that kill the plants that monarch caterpillars⑳ eat．[3] [3]此处两个that都是引导的定语从句。其中第一个that的先行词是chemicals；第二个that的先行词是plants。 ⑬solution n．解决，解决 方法 ⑭mystery n．难以理解的事物，谜 ⑮amazing adj．惊人的，了不起的 ⑯crash v．暴跌 ⑰per cent n．百分比 ⑱destroy v．破坏，毁掉 ⑲chemical n．化学品 ⑳caterpillar n．毛虫(蝴蝶等昆虫的幼虫) 　　The research on the monarch's behaviour has however led to a greater awareness㉑ of this creature㉒．People have been working together to record its migration and make sure that there are enough plants for it to feed on．[4]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 survive㉓ [5]and keep its place in the natural world for a long time to come． [4]此句运用了现在完成进行时。现在完成进行时表示过去某一时刻发生的动作一直持续到现在，并有可能继续持续下去。 [5]此句为“the＋比较级．．．，the＋比较级．．．”结构，意为“越……，越……”，是一个复合句，其中前面的句子是状语从句，后面的句子是主句。 ㉑awareness n．意识，认识 ㉒creature n．生物，动物 ㉓survive v．活下来，幸存 黑脉金斑蝶的迁徙之旅 　　许多动物会在一年中的某些时候从一个地方迁移到另一个地方，这种一年一度的运动叫作迁徙。它们为了觅食、寻找伴侣或温暖的环境而迁徙。北美黑脉金斑蝶的迁徙是大自然中最为美妙的迁徙之一。 　　每年秋天，数百万只有着黑色和橙色翅膀的漂亮的昆虫会开始一段漫长而艰难的旅程。不知怎么地，它们设法向南飞行大约4 000千米，前往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。 　　华盛顿大学伊莱·史利哲曼教授领导的科学家(研究)小组现在已经找到了答案。他们发现黑脉金斑蝶可以分辨出一天中的时刻。它用眼睛来测量太阳的位置。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。最终成功到达它要过冬的地方。 　　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。过去几年里，黑脉金斑蝶的数量骤减百分之九十。不幸的是，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，人们正在破坏自然环境。他们砍伐树木，所使用的化学品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使人们对这种生物有了更好的了解。人们一直齐心协力记录它的迁徙，并确保它有足够的植物可食用。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。 measure vt．量，测量；评估 vi．有……长/宽 n．尺寸；措施 【用法归纳】 (1)measure sth．by sth．
