2026年学霸组合训练八年级英语下册译林版扬州专版第12页答案
三、阅读理解(每小题 2 分,满分 30 分)
A
Eggshells(蛋壳) are very thin and are easy to break, but their shape enables them to
support a surprising amount of weight.
Want to have a try? Follow the steps in the experiment(实验) and see what will happen.
1. Lightly hit one end of an egg
and pour out the content.
2. Draw a line at the widest point
around the egg.
3. Cut around the line with scissors.
Prepare another three eggs in
this way. 
4. Put your eggs in a square.
Carefully lay a brick or more on top
of the shells. 
▲
An arch is strong because its shape evenly spreads the weight
that it supports. A dome is like a series of many arches arranged
(排列) in a circle. Your halved eggshells are mini domes.

(
D
)31. For this experiment,you need to prepare at least
eggs.
A. one
B. two
C. three
D. four
(
A
)32. What can be put in “▲”?
A. How does this work?
B. Why are eggs put in a square?
C. How much weight can eggshells support?
D. Which shape is stronger,an arch or a dome?
(
A
)33. Which of the following shows the similar principle(原理)in the reading material?

答案

【语篇解读】本文是一篇应用文。文章通过用鸡蛋壳做实验,告诉我们圆顶的承重力很强。
31. D 推理判断题。根据“Lightly hit one end of an egg and pour out the content.”和“Prepare another three eggs in this way.”可知做这个实验至少需要四个鸡蛋。故选 D。
32. A 补全文章题。根据“... Your halved eggshells are mini domes.”可知本段介绍了半蛋壳因为呈圆顶形而坚固,由此可知 A 项“它是如何奏效的?”符合题意。故选 A。
33. A 推理判断题。根据“An arch is strong because its shape evenly spreads the weight that it supports. A dome is like a series of many arches arranged in a circle.”可知本文介绍拱形和圆顶形的原理。故选 A。

解析

【分析】
这是一篇科普实验类的英语阅读理解,解题时可以按照题目顺序逐一对应原文信息推导答案:
1. 解第31题时,直接定位到实验步骤的第3步,先找到第一次处理的鸡蛋数量,再加上额外准备的鸡蛋数量,就能算出总需要的鸡蛋数;
2. 解第32题时,重点观察空后段落的内容,空后整段都在解释蛋壳能承重的底层力学原理,因此要选出能引出原理说明的过渡问句,排除和后文内容不匹配的选项;
3. 解第33题时,抓住文中核心的“拱形、圆顶结构均匀分散承重”的原理,匹配符合该原理的选项即可。
【解析】
31. 细节推理:根据实验步骤第3步的描述,先处理了1个鸡蛋,还需要用同样的方法另外准备3个鸡蛋,1+3=4,可知做该实验至少需要4个鸡蛋,因此选D。
32. 语篇补全:空后段落完整解释了拱形、圆顶的受力特点,说明蛋壳可以支撑大重量的原理:
选项A“这个实验是怎么起作用的?”刚好引出下文的原理解释,符合逻辑;
选项B询问鸡蛋摆成正方形的原因,后文没有相关对应内容,排除;
选项C询问蛋壳能支撑的重量数值,后文没有提及具体重量数据,排除;
选项D对比拱形和圆顶的强度,后文没有对二者做强弱对比,排除。因此选A。
33. 原理匹配:文中明确说明实验的核心原理是拱形、圆顶结构可以均匀分散所承受的重量,承重力更强,对应符合该力学原理的选项为A。
【答案】
31. D 32. A 33. A
【知识点】
阅读理解细节推理,语篇逻辑补全,科普类文本阅读
【点评】
本题属于实验科普类应用文阅读,考点设置贴合文本内容,既考查学生定位原文信息、梳理上下文逻辑的英语阅读能力,也融入了基础的建筑力学常识,兼顾了跨学科知识的运用,只要细心比对原文内容就可以顺利选出正确答案。
