Many animals migrate at certain times of the year for a variety of reasons. One of the most breathtaking migrations is the annual movement of the monarch butterfly. It uses its eyes to measure the position of the sun, which allows it to determine the way to go.
The solution to the mystery of the butterfly's amazing ability comes at a time when its population has crashed by as much as 90 per cent in the last few years. In many places where the creature can be found, people are destroying the natural environment by cutting down trees and using chemicals that kill the plants that monarch caterpillars eat. Fortunately, people have worked together to seek for ways to protect the butterflies and the population is recovering bit by bit eventually. After all, the more we concentrate on the butterflies, the greater the chance they will survive .
许多动物在一年中的某些时候会因为各种原因而迁徙。最令人叹为观止的迁徙之一是帝王斑蝶的年度迁徙。它用眼睛来测量 “太阳的位置”，从而确定前进的方向。
帝王斑蝶惊人能力之谜的谜底揭晓之时，其数量在过去几年中减少了百分之九十之多。在许多可以找到这种生物的地方，人们正在通过砍伐树木和使用杀死帝王斑毛虫所食植物的化学物质来破坏自然环境。幸运的是，人们齐心协力寻求保护帝王斑蝶的方法，其数量最终正在一点儿一点儿地恢复。毕竟，我们越关注帝王斑蝶，它们存活下来的机会就越大。

[选自：选修教材　人教版·选修一(新教材)　UNIT 1 P10]
The Grand Canyon① of the Colorado is a canyon composed of② many canyons. It is a complex mix of thousands, of tens of thousands, of gorges③. In a similar manner④， each wall of the canyon is a wall composed of many walls⑤. Every one of these gorges is a world of beauty in itself. Yet all these canyons unite to form one grand canyon, the most gorgeous spectacle⑥ on earth⑦.
The carving of the Grand Canyon is the work⑧ of rains and rivers. When a shower⑨ comes in this land, the streams carve canyons—but a little at each storm; and though storms are far apart⑩ and the heavens above are cloudless for most of the days of the year, still, years are plenty in the ages, and an occasional stream called to life by a shower can do much work in centuries of centuries.
①canyon n．峡谷
②(be) composed of由……构成
③gorge n．峡谷
④in a similar manner以类似的方式
⑤此处为过去分词短语作后置定语
⑥spectacle n．壮观的景象
⑦此处为同位语
⑧work (常用义) v．工作 (文章义) n．工作成果；作品
⑨shower (常用义) n．& v．沐浴 (文章义) n.阵雨
⑩far apart相距甚远
occasional adj.偶尔的

The Grand Canyon of the Colorado is a canyon composed of many canyons. It is a complex mix of thousands, of tens of thousands, of gorges.
→_____________________________________________________________________________________________________________________________________
The Grand Canyon of the Colorado, a canyon composed of many canyons, is a complex mix of thousands, of tens of thousands, of gorges.
2．What is the composition of the Grand Canyon of the Colorado
________________________________________________________________________________________________
The Grand Canyon of the Colorado is composed of thousands or even tens of thousands of gorges.
【识文知意】　科罗拉多大峡谷是由许多峡谷组成的一个大峡谷。它是由成千上万条峡谷复杂交织而成的。同样地，大峡谷的每一面墙都是由许多墙壁构成的。这些峡谷中的每一个都是一个美丽的世界。然而，所有这些峡谷结合在一起，形成了一个宏伟的大峡谷，这是地球上最壮丽的奇观。
大峡谷的雕刻是雨水和河流的作品。当这片土地迎来一场阵雨时，溪流便开始雕刻峡谷——但每次暴雨只能雕刻一点点；尽管暴风雨相隔甚远，而且一年中大部分时间天空都是无云的，但在漫长的岁月中，(下雨的)年份是很多的，一场偶然的阵雨会唤醒的溪流在成千上万年里可以发挥很大的作用。
