Small Ideas That Changed the World
When we think of great inventions, we often imagine complex machines or high technology. However, some of the most important inventions in human history are surprisingly simple. Here are three small ideas that had a huge impact.
The Wheel
The wheel was invented around 3500 BC． It may seem obvious today, but it was a revolutionary idea. Before the wheel, people had to carry heavy loads themselves or use animals. The wheel made transportation much easier and faster. It led to the development of carts, chariots, and eventually all modern vehicles.
Paper Money
Before paper money, people used coins made of gold, silver, or other metals. These were heavy and inconvenient to carry. The Chinese invented paper money during the Tang Dynasty (618-907 AD). It was light, easy to carry, and could be printed in different values. This idea changed the way business was done all over the world.
The Zipper
The zipper was patented in 1917 by Gideon Sundback. Before zippers, people used buttons and hooks to fasten clothing. Buttons took time, and hooks could be dangerous. The zipper was quick, safe, and convenient. It was soon used in clothing, bags, and shoes. Today, we can hardly imagine life without it.
These inventions remind us that creative ideas do not have to be complicated. Sometimes the most powerful ideas are the simplest ones. So keep your eyes open — the next great invention could be something very small.
36．When was the wheel invented
A．Around 3500 BC． B．During the Tang Dynasty.
C．In 1917. D．Around 618 AD．
37．What problem did paper money solve
A．It was too easy to make coins.
B．Coins were heavy and inconvenient.
C．People didn’t like using metal.
D．Coins were not valuable enough.
38．What made the zipper better than buttons and hooks
A．It was more expensive.
B．It was quicker, safer, and more convenient.
C．It was made of metal.
D．It was more beautiful.
39．The three inventions mentioned in the passage all have one thing in common: they are ________.
A．very complicated B．powered by electricity
C．surprisingly simple D．made of metal
40．What is the main message of the passage
A．Only big inventions change the world.
B．Modern technology is better than old inventions.
C．Simple ideas can also have a great impact.
D．The wheel is the most important invention.

Have you ever seen or used a saw, or ju in Chinese Do you know who invented it
The inventor was Lu Ban. He was born in the state of Lu in ancient China more than 2,500 years ago. That is where Qufu lies in the east of Jining.
Lu Ban was the greatest carpenter (木匠) in his time. Once the king ordered him and his team to build a palace in a very short time. They would be punished if they missed the deadline (最后期限). They had only axes, or fuzi in Chinese, to cut the trees and prepare the wood for the palace, so the work went very slowly.
One day Lu Ban rushed up the hill to see how things were going. Suddenly the sharp teeth of a leaf cut his hand. Then a bright idea came into his head. Soon he made a tool with teeth along the side of a long iron bar (条状物). With this tool, work became much faster, and they completed the work before the deadline.
That is how the saw was invented.
Lu Ban invented many other useful tools for carpenters and interesting toys for children. The Wooden Bird, for example, could stay in the air for three days!

【详解】56．句意：大多数人都知道电话是亚历山大 格雷厄姆 贝尔于1876年发明的。主语“the telephone”和动词“invent”之间是被动关系（电话“被发明”）。句中“in 1876”是过去时间，用一般过去时被动语态，结构：was/were+过去分词。主语单数，故填was invented。
57．句意：但很少有人知道另一位发明家伊莱沙 格雷在同一天提交了相似的专利申请。表示具体某一天，应用介词on。
58．句意：事实上，当时两人都在研究通过电线传输声音的构想。语境描述1876年那个时间段，两人正在同步钻研这项技术，用过去进行时。主语”both men”是复数，be动词用“were”，“work”变“working”。
59．句意：电话的故事表明，不同的人常常会在同一时间创造出发明。主语“inventions”和“create”之间是被动关系（发明 “被创造”）。空前有“are”，一般现在时被动结构：are+过去分词，“create”的过去分词为“created”。
60．句意：这就是你要尽快落实自己想法的原因。固定句型：That is why...，表示“这就是……的原因”，why引导表语从句，用来引出前文现象对应的结论。
61．句意：自问世以来，电话在诸多方面改变了世界。“Since its invention”是现在完成时标志性时间状语，强调动作从过去持续到现在。主语“the telephone”为单数，助动词用“has”，“change”变过去分词“changed”。
62．句意：如今智能手机的用途远不止打电话。固定结构：be used to do sth.表示 “某物被用来做某事”，不定式to do作目的状语。
63．句意：然而，一些人担心我们正变得过度依赖科技。表达当下现阶段持续发生、逐步变化的状态，用现在进行时。主语是“we”， be动词用“are”，“become”变“becoming”。
64．句意：他们认为面对面的交流应当被更加重视。主语“face-to-face communication”和“value”之间是被动关系。情态动词被动语态固定结构：should be+过去分词，value的过去分词为“valued”。
65．句意：问题不在于我们该不该使用它，而在于我们该如何明智地使用它。固定并列结构not...but...，表示“不是……而是……”，用于转折对比两个并列从句。

The Power of Ideas
Ideas have great power. They can change our lives. Many great inventions come from good ideas.
When we have new ideas, we should try to make them come true. Sometimes our ideas may fail. But we shouldn’t give up. Great inventions were improved many times before they became popular.
Everyone can have creative ideas. We should keep thinking and creating. Good ideas can make our world better.
As teenagers, we should dare to imagine. Our small ideas may bring amazing changes one day.
