The Monarch's Journey
Many animals move from one place to another at certain times of the year.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 nature is that of the North American monarch butterfly.
Every autumn, millions of these beautiful insects with fine black and orange wings begin a long and difficult journey.Somehow 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.(1)
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,这种一年一度的移动被称为迁徙。它们迁徙是为了寻找食物,寻找伴侣,或者寻找更温暖的天气。北美黑脉金斑蝶的迁徙是大自然中最令人惊奇的迁徙之一。
每年秋天,数百万只黑脉金斑蝶会开始一段漫长而艰难的旅程。这些漂亮的昆虫翅膀上有着漂亮的黑色和橙色斑纹。不知怎么地,它们设法向南飞行大约4000千米,前往加利福尼亚或墨西哥。然而,直到最近,也没有人知道它们是如何做到这一点的。

(1)how they did this是how引导的宾语从句,作knew的宾语。
A team of scientists led by Professor Eli Shlizerman at the University of Washington (2) 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(3)—allow the butterfly to determine the way to go. Eventually, it manages to reach the places where it will spend the winter (4).
由华盛顿大学伊莱·史莱泽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的时刻。它用眼睛来测量太阳的方位。这两条信息——一天中的时刻和太阳在天空中的方位——让黑脉金斑蝶决定它飞行的路线。最终它成功到达它将过冬的地方。
【助读点拨】
(2)led by...Washington 是动词-ed形式作后置定语,修饰A team of scientists。
(3)本句中the time of day and the point where the sun is in the sky 是information的同位语;where the sun is in the sky是where引导的定语从句,修饰先行词the point。
(4)where it will spend the winter是where引导的定语从句,修饰先行词the places,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, people are destroying the natural environment.They cut down trees and use chemicals that kill the plants that monarch caterpillars eat(7).
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。在过去的几年里,黑脉金斑蝶的数量骤减了90%。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,使用化学药品,这些药品会杀死黑脉金斑蝶幼虫吃的植物。
【助读点拨】
(5)when it is in serious trouble 是when引导的定语从句,when在从句中作时间状语。
(6)why the number of monarch butterflies is falling是why引导的定语从句,why在从句中作原因状语。
(7)that kill...eat是that引导的定语从句,修饰先行词chemicals,that在该从句中作主语;that monarch caterpillars eat也是that引导的定语从句,修饰先行词plants,that在该从句中作宾语。
The research on the monarch's behaviour has however led to a greater awareness of this creature.People have been working together to record its migration and make sure that there are enough plants for it to feed on.(8) 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.(9)
然而,对黑脉金斑蝶行为的研究使人们对这种生物有了更深的认识。人们一直共同努力记录它的迁徙,并确保它有足够吃的植物。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。我们对这种可爱的生物了解得越多,它生存的机会以及在未来很长一段时间内保持它在自然界中的地位的可能性就越大。
【助读点拨】
(8)本句中have been working 是现在完成进行时,表示动作从过去某时开始,一直延续到现在,还可能延续下去。
(9)The more...,the greater...是“the +比较级,the +比较级”结构,表示后者随着前者的变化而变化。
