Leizu learned how to make cocoons（蚕茧） into soft and strong cloth. This magical cloth became known as “silk”， and it was so valuable that it was called “China’s Gold”. Following kings’ orders， the Chinese kept the secret of making silk for centuries. But then， something amazing happened！ During the Han Dynasty， the brave officer Zhang Qian travelled west as far as Central Asia and brought silk there. As years passed， silk became so important that the trade road from Europe to China got its name—the Silk Road. The Silk Road became a busy highway for traders who carried things across deserts and mountains. From China， people sold silk and tea. In return， they received treasures such as spices（香料）， gold and silver from the West. In the very beginning， it was mainly about trade； then people began to share ideas， technologies and cultures. For example， Chinese inventions like papermaking were spread to the West， while new ideas about math and science came to China. Most importantly， the Silk Road helped different cultures learn from each other. Art， music and even language were shared along this ancient road. In places like the Dunhuang Grottoes（敦煌石窟） in China， you can see how art pieces combined（融合） Eastern and Western styles into something distinctive. It cannot be seen anywhere else. The story of the Silk Road tells us how people from faraway lands could become friends through trade and shared ideas. Today， we remember the Silk Road as one of the greatest examples of cooperation and exchange in history. It shows us how important it is to learn about and respect each other’s traditions， and that different cultures can work together to create amazing things. 1. Who invented silk in ancient China？ A.

Among 2.  　 　（hundred） of modern inventions， 3D printing stands out as a super one that turns ideas into reality in hours. This technology allows us to produce special objects—3.  　 　 tools to artworks—by stacking materials like plastic. Its magic lies not just in speed， but in how it helps develop creativity 4.  　 　（it）. The process begins digitally： a design file guides the 5.  　 　（print） to build objects layer upon layer. For example， small plastic toy cars—once expensive and slow to print—can now 6.  　 　（create） affordably. What needed weeks to make in the past now takes just a few hours. This technology has brought big changes to fields such as medicine and engineering. Scientists continue 7.  　 　（invent） new ways to use this technology.

Old wearable technology like eyeglasses has helped many people see clearly. Wearable（可穿戴的） technology has changed how we play， communicate， and take care of our health. Today’s wearable devices（装置） have many great functions. 1.  　　 Modern wearable technology began around 2008. That was when fitness trackers（追踪器） like the Fitbit hit the market. These devices can track your heart rate and count your steps. A few years later， smartwatches appeared. 2.  　　 What’s more， they can show text messages and let you make phone calls. Now you can even buy smart clothes， such as pants that vibrate if your exercise posture is wrong. Wearable technology has other uses too. It lets people play video games on virtual reality devices like the Oculus Quest. Medical workers have also started using implantable（植入的） devices. 3.  　　 One example is smart pills. They can send health information from your stomach to a smartphone. Today’s wearable technology is interesting， but the future of wearable technology is simply amazing. New products like self-powered electronics and smart contact lenses（隐形眼镜） are on the way. The next wearable devices will change our lives in exciting ways. 4.  　　 For example， scientists are making smart shoes with a special battery. The battery stores energy when you walk. Wearing these shoes is like having a portable charger on your feet that gets power with every step you take. Contact lenses are also getting a big upgrade. Scientists are working on smart contact lenses that act as computerized personal assistants. They can track your eye movements and offer help automatically. They may even be able to check your tears to figure out how you’re feeling. 5.  　　 Today， devices like fitness trackers are changing how we learn about our own bodies. It makes you think： What amazing things will future wearable technology do to make our lives better？ Unit 5 Power of Ideas Section A　What changes can inventions bring to our lives？ 第3课时　Grammar Focus [课堂再现] 1.

Now it has beaten its own record with an even higher bridge—one that is 2，051 feet above the Beipan River in Guizhou. The bridge is expected to make travel much faster and to bring tourists to the area. The Huajiang Grand Canyon is one of the things that used to make travelling in Guizhou so hard. The canyon is so deep and long that it is sometimes called the “Earth’s Crack”. The entire bridge is 1.8 miles long. The bridge took three years to build and cost about $295 million. It is now part of the Guizhou S57 highway. Driving across the bridge is convenient. It takes just a little more than a minute. However， before the bridge was built， people had to walk on long， winding（蜿蜒的） roads along the canyon to get through the mountains. The bridge’s builders have turned it into a place that helps local tourism. There is a special glass walkway that allows visitors to look down at the river deep in the valley. Tourists can take a glass elevator to visit a glass-walled restaurant high up in one of the towers. The restaurant sits half a mile up in the air. In the 1980s， the province had less than 3，000 bridges. It now has over 32，000 of them， including almost half of the world’s 100 tallest bridges. 根据短文内容，回答下列问题。 1. Which country holds the record for the world’s tallest bridge now？ 2. How long is the tallest bridge in the world？ 3. What special facilities does the bridge have for tourists？ 4.

Now it has beaten its own record with an even higher bridge—one that is 2，051 feet above the Beipan River in Guizhou. The bridge is expected to make travel much faster and to bring tourists to the area. The Huajiang Grand Canyon is one of the things that used to make travelling in Guizhou so hard. The canyon is so deep and long that it is sometimes called the “Earth’s Crack”. The entire bridge is 1.8 miles long. The bridge took three years to build and cost about $295 million. It is now part of the Guizhou S57 highway. Driving across the bridge is convenient. It takes just a little more than a minute. However， before the bridge was built， people had to walk on long， winding（蜿蜒的） roads along the canyon to get through the mountains. The bridge’s builders have turned it into a place that helps local tourism. There is a special glass walkway that allows visitors to look down at the river deep in the valley. Tourists can take a glass elevator to visit a glass-walled restaurant high up in one of the towers. The restaurant sits half a mile up in the air. In the 1980s， the province had less than 3，000 bridges. It now has over 32，000 of them， including almost half of the world’s 100 tallest bridges. 根据短文内容，回答下列问题。 1. Which country holds the record for the world’s tallest bridge now？ China. 2. How long is the tallest bridge in the world？ 1.8 miles long. 3. What special facilities does the bridge have for tourists？ It has a special glass walkway and a glass-walled restaurant. 4. How many bridges does Guizhou have now？ It now has over 32，000 bridges. 5.
