C
When Qin Shihuang became the first emperor of China, he wanted to unify the country in many ways. One big problem was money. Different places used different coins. Some were shaped like knives, others were like shells, and they had different weights. No one knew if a coin from one place had the same value as another. This made trading between places hard.
So Qin Shihuang decided to make one kind of coin for the whole country. It was called Banliang. It was round with a square hole in the middle. The hole was useful. People could put coins together with a rope. It made them easy to carry in pockets or bags.
The weight of each Banliang was half a liang. That's why it got the name "Banliang". The emperor sent officers to check that if all coins were made correctly. This let everyone know how much the value of each coin was. Farmers used them to buy tools, and businessmen used them to sell silk and tea across the country.
Qin Banliang made buying and selling easier everywhere, and also let people from different places work together. It helped make the country together. It also teaches us that having the same rules can bring people together and make life better for everyone.

C
11. B 由后文的problem及different可推断,当时的国家面临着诸多"不统一"。由此推断"unify"意为"统一;使团结",与"bring together"意思相近。故选B。
12. B 由第一段中提到"No one knew if a coin from one place had the same value as another."可知,当时各地货币不同导致价值不统一,这是主要问题。故选B。
13. C 综合第二段内容可知,第二段主要介绍了秦半两外圆内空的作用。故选C。
14. A 由上下文可知,秦始皇派官员检查货币是否合格。故选A。
15. B 由文章最后一句句意可知,相同的规则有利于团结协作,这既是全文主旨的升华,也是秦半两带给我们的启示。故选B。

【分析】
这是一篇介绍秦始皇统一货币秦半两的文化类阅读理解题，解题时可以按照以下思路推进：1. 先通读全文，梳理文章脉络：先点明秦始皇要从多方面统一国家，当时各地货币形制不一带来交易难题，接着介绍秦半两的形制、命名由来、监管方式，最后点明统一货币带来的意义和启示。2. 针对不同题型匹配对应方法：词义猜测题结合上下文的“各地货币不同、后续推行统一货币”的语境推断词义；细节理解题直接根据题干关键词回原文定位对应语句，比对选项选出答案；段落主旨题梳理段落所有内容，提炼核心描述对象，排除片面选项。
【解析】
11. 词义猜测题：根据后文提到的“不同地区使用不同钱币、后续秦始皇将全国货币统一为一种”的内容，能推断出秦始皇想要从多方面统一国家，单词unify意为“统一，使聚合到一起”，A选项Divide（分割）含义相反，C选项Beat（击败）不符合语境，D选项Build（建造）不符合，只有B选项Bring together（使汇聚、统一）和词义匹配，故选B。
12. 细节理解题：题干询问不同货币带来的问题，直接定位到第一段原文“No one knew if a coin from one place had the same value as another”，可知人们无法判断不同地区的钱币是否拥有同等价值，A选项“所有钱币都太重”、C选项“钱币用劣质金属制作”、D选项“钱币太小不好用”原文均未提及，故选B。
13. 段落主旨题：第二段先介绍全国推行的新货币是半两钱，重点描述了钱币中间方孔的作用——可以用绳子把钱币串起来，方便放在口袋或包里携带，核心内容是介绍半两钱中心方孔的主要用途，A选项“半两钱命名的由来”是第三段内容，B选项“谁决定制作半两钱”只是段落开头的小细节，D选项“半两钱的孔在哪里”完全偏离段落核心，故选C。
14. 细节理解题：题干询问秦始皇如何保证钱币制作合格，定位到第三段原文“The emperor sent officers to check that if all coins were made correctly”，可知秦始皇派遣官员检查钱币是否制作达标，其余选项均不是保证钱币合规的方式，故选A。
15. 主旨启示题：文章最后一句点明核心道理“It also teaches us that having the same rules can bring people together and make life better for everyone”，即统一的规则能够帮助人们凝聚协作，其余选项都是不符合原文的错误表述，故选B。
【答案】
11. B 12. B 13. C 14. A 15. B

阅读理解细节查找，词义猜测，段落主旨提炼
【点评】
本题属于文化类基础阅读题，绝大多数考点都可以通过直接定位原文语句得到答案，难度较低，既考察了学生的基础信息提取能力，也融入了中国古代经济史的相关常识，仅第13题容易误选片面的细节选项，需要学生注意区分段落的核心描述和零散的次要信息。
