Ⅳ.(2026·宿迁沭阳怀文中学阶段检测)阅读理解
Nature is amazing! Take a close look at the world of insects(昆虫), and you'll find many unbelievable things. Think about butterflies, for example. They have beautiful colourful wings and strong fantastic flying skills. In summer, you can see them flying freely over flower gardens and wild fields.
But do you know how butterflies become 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 turns into a walking insect. This insect is called a caterpillar(幼虫). 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 a 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 into the woods and mountains and see what you can find next.

答案

Ⅳ. [文章大意]本文是一篇说明文,以蝴蝶为例展现自然界的奇妙,主要介绍了蝴蝶从卵、幼虫、蛹到成虫的完整生命周期。1. D [解析]细节理解题。根据第一段中的“Take a close look at the world of insects(昆虫), and you'll find many unbelievable things. Think about butterflies, for example.”可知,符合A项内容“蝴蝶是一种昆虫”;根据第一段中的“They have beautiful colourful wings and strong fantastic flying skills.”可知,符合B项“蝴蝶擅长飞行”和C项“蝴蝶有五颜六色的翅膀”内容。只有D项未提及。故选D。2. B [解析]词义猜测题。根据第四段中的“Soon, after growing big, the caterpillar makes a cover for itself. It covers itself in a protective blanket(保护层) and goes to sleep. This stage is known as the 'pupa(蛹)' stage.”可知,“cover”是毛毛虫为了在蛹期保护自己而制作的东西。故选B。3. B [解析]标题归纳题。文章介绍了蝴蝶的四个生命阶段(卵、幼虫、蛹、成虫),“One insect, four lives(一种昆虫,四种生命形态)”能概括核心内容。故选B。4. A [解析]篇章结构题。通读全文可知,①为总起,举例说明大自然中的昆虫世界很神奇,引出下文;②③④⑤介绍了蝴蝶从卵变成蝴蝶的过程;⑥为总结,介绍了自然世界中还有很多神奇的东西。故选A。5. I think the pupa stage is the most amazing because it changes completely inside, and later it becomes a beautiful flying butterfly.(开放性题目,言之有理即可)

解析

【分析】
这是一篇初中阶段的自然科普类阅读理解题,核心围绕蝴蝶的生长发育周期展开。解题时首先可以先梳理语篇逻辑:开篇总述自然界存在很多奇妙的现象,以蝴蝶作为引入案例,后续按照时间顺序依次介绍蝴蝶从产卵、孵化成幼虫、进入蛹期、最终破茧成蝶完成生命周期的全过程。当前提供的阅读文本未完全收尾,也未配套对应的具体考题设问,仅可先梳理已给出内容的核心信息,无法开展针对性的题目作答。
【解析】
本次给出的语篇属于不完整的科普阅读材料,缺少收尾的文本内容,也没有配套对应的阅读理解具体设问,仅可梳理已呈现部分的核心信息:
1. 开篇总述:大自然十分神奇,蝴蝶有着艳丽多彩的翅膀和出色的飞行能力,夏季常能在花园、野外看到它们自由飞舞。
2. 蝴蝶的完全变态发育过程:
① 初始阶段:雌性蝴蝶会将小巧的彩色卵产在植物的叶片或者茎上;
② 幼虫阶段:卵孵化成毛毛虫(caterpillar),长有腿、眼睛和肥大的躯体,可以进食、移动、视物,但此时还不是蝴蝶;
③ 蛹期阶段:毛毛虫长大之后会为自己制作一层保护性的覆盖层,进入休眠状态,这个阶段被称为蛹期;
④ 成虫阶段:一段时间后蛹的保护层破裂,刚羽化的蝴蝶湿润虚弱,待翅膀充血完全舒展后就可以飞走;
3. 成年蝴蝶在数周后就会产卵,整个生命周期就会重新循环。
【答案】
答案略
【知识点】
英语阅读理解,昆虫发育常识
【点评】
这是一篇难度偏低的科普类阅读语篇,行文逻辑清晰,以时间线推进内容,陌生专有名词都附带中文注释,很适合初中学生练习细节信息定位类的阅读题型,既能训练英语阅读能力,也能补充相关的自然科学常识。
【难度系数】
0.7

【分析】
这是一篇介绍蝴蝶完整生命周期的说明文阅读,解题时可以按照不同题型的对应思路逐一突破:
1. 第1题是细节理解题,首先明确题干要求选出第一段没有提及的内容,直接定位到原文第一段,将四个选项的描述和原文内容逐一对照,排除原文明确提到的选项,剩下的就是未提及的答案。
2. 第2题是词义猜测题,定位划线单词所在的第四段,结合后文对该事物的描述,判断cover的含义,排除不符合语境的选项。
3. 第3题是标题归纳题,需要通读全文抓住核心内容,文章围绕蝴蝶的卵、幼虫、蛹、成虫四个生命阶段展开,选出最能覆盖全文主旨的标题即可。
4. 第4题是篇章结构推断题,逐段概括每段的作用,区分总起段、分述段、总结段,匹配对应的结构选项。
5. 第5题是开放性表达题,结合蝴蝶生命周期任意一个你觉得神奇的点,用通顺的英文表述,言之有理即可。
【解析】
1. 细节比对:原文第一段明确提到蝴蝶属于昆虫,拥有色彩艳丽的翅膀和极强的飞行能力,并未提及蝴蝶有良好的嗅觉,因此对应选D。
2. 语境推导词义:第四段说明毛毛虫长大后会自己制作一个保护层,将自己包裹起来进入蛹的阶段,因此cover是毛毛虫为了保护自己制作的东西,对应选B。
3. 主旨提炼:全文核心介绍蝴蝶这一种昆虫的四个完全不同的生命阶段,"One insect, four lives"可以完整概括全文内容,其余选项都只能覆盖部分内容,对应选B。
4. 结构梳理:第1段总起引出昆虫世界很神奇的话题,第2-5段分别介绍蝴蝶从卵到成虫的完整生长过程,第6段总结呼吁大家探索自然的更多奥秘,对应结构①/②③④⑤/⑥,选A。
5. 开放作答:任选蝴蝶生命周期的任意阶段说明理由,表述通顺、逻辑合理即可。
【答案】
1. D
2. B
3. B
4. A
5. I think the pupa stage is the most amazing because it changes completely inside, and later it becomes a beautiful flying butterfly.(言之有理即可)
【知识点】

【点评】
本题属于初中英语阅读理解典型题型,在常规细节题、词义猜测题的基础上加入了标题归纳、篇章结构推断、开放表达的新考法,既考察学生对文本零散信息的抓取比对能力,也锻炼学生梳理全文逻辑、提炼核心主旨的能力,同时引导学生结合文本内容输出个人观点,符合新课标对英语学科核心素养的考察要求。
