B
Long ago, people didn't use money. They traded things directly. In fact, trading was hard at that time. Sometimes people spent hours talking about a trade and didn't agree on it at last only because the farmer thought his chicken was bigger than the baker's bread.
Then, people started using "money" from nature like shells, stones, or even animal teeth. These were easy to carry and everyone agreed that they had value. For example, a shell might buy a bag of corn, and two shells could buy a piece of meat. This made trading faster. Later, metal coins appeared. They were easier to count and carry. The first coins had simple shapes, for example, the coins of the Qin Dynasty. They were round pieces of metal with a square hole in the center, and they worked well for hundreds of years. ▲ They had pictures of famous people or symbols of their countries.
Today, we use paper money and digital payments. But the idea is the same: money helps us get what we need. From shells to phone Apps, money has changed a lot. It shows how people worked together to make life easier. Every step of this change comes from people wanting to trade fairly. This progress connects all of us; no matter where we live, we can share goods and ideas with money across the world.

8. B 由第三段倒数第二句“Every step of this change comes from people wanting to trade fairly.”可知,货币的发展是由人们对公平交易的需求推动的。故选B。
9. D 由空白处后一句可知,硬币上出现了名人或国家象征的图案,由此推断硬币变得更精细。故选D。

【分析】
这是一篇介绍货币演变历史的说明文阅读理解，解题时可以按照"题干划关键词→回原文定位对应内容→比对选项排除错误项"的思路推进：首先针对细节类题目，直接找到题干对应的原文段落，把选项和原文表述逐一匹配就能选出正确答案；针对句子还原题，要观察空白处前后的内容逻辑，选出衔接最顺畅的选项；针对主旨题，梳理全文的时间线脉络，排除片面的干扰选项，就能得到核心主旨。
【解析】
6. 定位原文第一段内容："Sometimes people spent hours talking about a trade and didn't agree on it at last only because the farmer thought his chicken was bigger than the baker's bread"，说明古代物物交换的核心难点是交易双方很难对公平的交易标准达成共识，A、C、D选项的内容在原文完全没有提及，因此选B。
7. 定位原文第二段第一句"Then, people started using "money" from nature like shells, stones, or even animal teeth"，原文明确提到古代曾把贝壳、石头、动物牙齿作为货币使用，没有提到水可以充当货币，因此选D。
8. 定位原文最后一段"Every step of this change comes from people wanting to trade fairly"，直接点明货币发展的每一步都来源于人们对公平交易的需求，其余选项的表述原文均无对应依据，因此选B。
9. 空白处前文介绍了秦代样式简单的方孔圆钱，后文提到硬币上印有著名人物肖像或者国家象征图案，前后逻辑是硬币从简单样式发展到有精细的图案设计，A和前文的"早期硬币样式简单"内容重复，B的纸币话题和上下文的硬币语境不匹配，C的贝壳内容和当前讲金属硬币的段落无关，因此选D。
10. 全文按照时间顺序，从最开始的直接物物交换，到贝壳石头等自然货币，再到金属硬币，最后到当代的纸币和数字支付，完整介绍了货币的发展历史和演变过程，A选项的收藏古币贝壳原文完全未涉及，B选项只讲现代货币的重要性过于片面，D选项不同国家造币的内容不是文章核心，因此选C。
