Nature is amazing! Take a close look at the world of insects(昆虫), and you’ll discover many unbelievable things. Consider butterflies, for example. They have beautiful, colourful wings, and strong, fantastic flying skills. On summer days, you always see them flying freely over flower gardens and wild fields.
But, do you know how butterflies become the flying insects? It’s one of the amazing wonders of nature. In the beginning, female butterflies lay a small and colourful egg on a leaf or stem(茎) of a plant.
It’s hard to believe that the egg will become something completely different in a few days. It becomes a walking insect. This insect is called caterpillar. It now has legs, eyes and a large body. A new life has begun. The caterpillar can eat, walk and see. But it is still not a butterfly.
Soon, after growing big, the caterpillar makes a cover for itself. It covers itself in the nice protective blanket(保护层) and goes to sleep. This stage is known as the “pupa(蛹)” stage.
After a period of time, the blanket breaks and a wet, weak butterfly appears. It now has six legs, a mouth, eyes and wings. Shortly, the wings fill with blood, and the beautiful, colourful butterfly spreads its wings and flies away.
After a few weeks, this adult butterfly lays her eggs, and the cycle begins all over again.
This is just one example of the wonders of nature. Look around the natural world, and you will learn many truly amazing things.

答案
1. D 【点拨】短文第一段提到了蝴蝶是一种昆虫、有颜色鲜艳的翅膀并善于飞行。文中没有提到它有良好的嗅觉。故选 D。
2. C 【点拨】根据短文第二至五段可知，先是雌性蝴蝶产下卵，卵孵化成幼虫，幼虫变成蛹，最后由蛹蜕变成蝴蝶。故正确顺序应该是 C 项。故选 C。
3. B 【点拨】阅读全文可知，本文主要介绍了蝴蝶一生的四个阶段。故选 B。
2. C 【点拨】根据短文第二至五段可知，先是雌性蝴蝶产下卵，卵孵化成幼虫，幼虫变成蛹，最后由蛹蜕变成蝴蝶。故正确顺序应该是 C 项。故选 C。
3. B 【点拨】阅读全文可知，本文主要介绍了蝴蝶一生的四个阶段。故选 B。
解析
【分析】
这是一篇科普类阅读理解题，解题思路如下：
1. 第1题属于细节排除题，首先明确题干要求选出第一段没有提及的内容，先定位到原文第一段，将四个选项的描述逐一和第一段内容比对，把明确提到的选项排除，剩下的就是未提及的正确答案。
2. 第2题是事件排序题，需要顺着文章介绍蝴蝶发育过程的段落，依次找到每个阶段的先后顺序，先确定发育的第一步是产卵，就能直接排除开头不是③的A、B选项，再对比剩下的C、D选项的后续顺序，回到原文确认蛹和破茧飞出来的先后，就能选出正确顺序。
3. 第3题是主旨大意题，通读全文抓住核心内容：文章全程介绍蝴蝶从卵到毛毛虫、再到蛹、最后成为成虫的四个不同生命阶段，对比四个选项排除以偏概全、不符合内容的干扰项，选出最贴合全文的标题。
【解析】
1. 定位原文第一段内容：文中明确提到蝴蝶属于昆虫，拥有色彩艳丽的翅膀，还有出色的飞行能力，A、B、C三项均有提及，全文没有任何内容介绍蝴蝶的嗅觉，因此未提及的是D选项。
2. 梳理蝴蝶的发育流程：首先雌性蝴蝶产下卵（对应③），之后卵变成可以爬行的昆虫也就是毛毛虫（对应②），之后毛毛虫给自己做保护层进入蛹阶段（对应①），最后破茧成为蝴蝶展开翅膀飞走（对应④），正确顺序为③→②→①→④，对应C选项。
3. 全文围绕蝴蝶的四个完全不同的生命发育阶段展开，A选项仅提及颜色过于片面，C选项介绍蝴蝶种类不符合原文内容，D选项介绍蝴蝶习性也和核心内容不符，只有B选项“一只昆虫，四种生命形态”最能概括全文内容，因此选B。
【答案】
1. D 2. C 3. B
【知识点】
细节信息定位，事件逻辑排序，主旨大意归纳
【点评】
本题属于难度偏低的科普类阅读题，考点覆盖了初中英语阅读最基础的三类常规题型，学生只要能带着题干关键词快速回原文定位对应内容，就可以轻松选出答案，能够有效锻炼学生快速抓取文本关键信息的能力。
