bottle can "eat" an egg! Let's try this fun experiment.
Materials
• a peeled, hard-boiled egg
• matches
• some small pieces of paper
• a glass bottle with a mouth smaller than the egg
Steps
• Put some pieces of paper inside the bottle.
• Light three matches together.
• Put the burning matches into the bottle.
• Quickly put the egg on the mouth of the bottle.
Happening
The egg begins to slowly move into the bottle.
Reasons
1. The burning matches' flame heats the air inside the bottle. The air expands(扩大) and some gets out of the bottle.
2. Then, after the egg is put on the bottle's mouth, the burning paper inside uses up the oxygen(氧气) and finally goes out.
3. After that, the air inside cools down and contracts(收缩). This creates a lower air pressure inside the bottle. Therefore, the higher air pressure outside pushes the egg into the bottle.
21. How many steps are there in this experiment?
A. Two. B. Three. C. Four. D. Five.
22. What finally makes the bottle "eat" the egg?
A. The burning paper outside the bottle.
B. The burning matches outside the bottle.
C. The different air pressure inside and outside the bottle.
D. The different temperatures inside and outside the bottle.
23. In which part of a magazine can you read this passage?
A. Art. B. Food. C. History. D. Science.

答案
21.C 22.C 23.D
A
【语篇解读】本文是一篇应用文。文章主要介绍了趣味科学实验“瓶子吃鸡蛋”的材料、步骤、现象和原理。
21. C 解析：细节理解题。根据“· Put some pieces of paper inside the bottle. · Light three matches together. · Put the burning matches into the bottle. · Quickly put the egg on the mouth of the bottle.”可知实验共有四步。故选C。
22. C 解析：细节理解题。根据“This creates a lower air pressure inside the bottle. Therefore, the higher air pressure outside pushes the egg into the bottle.”可知瓶子内外的气压差最终让瓶子“吃”了鸡蛋。故选C。
23. D 解析：推理判断题。结合文章内容可知，本文介绍了趣味科学实验的材料、步骤、现象和原理，会出现在杂志的科学板块。故选D。

解析
【分析】
本题为英语阅读理解题，包含3道基础题型，解题思路如下：
1. 第21题是细节理解题，需定位文章中“Steps”板块的内容，统计实验步骤的数量即可得出答案。
2. 第22题是细节理解题，需定位文章中“Reasons”板块的内容，找到使瓶子“吃”鸡蛋的最终原因。
3. 第23题是推理判断题，需结合文章介绍的趣味科学实验的性质，判断其所属的杂志板块。
【解析】
21. 细节理解题。根据文章“Steps”部分列出的4条内容（①Put some pieces of paper inside the bottle. ②Light three matches together. ③Put the burning matches into the bottle. ④Quickly put the egg on the mouth of the bottle.），可知实验共有四步，故选C。
22. 细节理解题。根据文章“Reasons”部分最后一句“This creates a lower air pressure inside the bottle. Therefore, the higher air pressure outside pushes the egg into the bottle.”可知，瓶子内外的气压差最终使瓶子“吃”了鸡蛋，故选C。
23. 推理判断题。文章主要介绍了“瓶子吃鸡蛋”的趣味科学实验，涉及物理气压知识，这类内容通常会出现在杂志的科学板块，故选D。
【答案】21.C 22.C 23.D
【知识点】英语阅读理解、细节理解题、推理判断题
【点评】本题为跨学科英语阅读题，结合物理实验知识，重点考查学生查找细节信息和推理判断的能力，题型基础，贴近生活，能激发学生对科学的兴趣。
【难度系数】0.8
