It's necessary for growing the food and resources we depend on, protecting against drought and flooding and storing carbon dioxide for years to come. But the dirt under our feet is constantly in danger because of rising temperatures and loss of biodiversity caused by climate change. Although we may think soil is simple, it's pretty hard to know what's really going on deep in the ground from the surface. Scientists in Italy, however, think they may have a robotic solution — a seed-inspired robot. Scientists at the Bioinspired Soft Robotics (BSR) Lab have developed the first 4D-printed seed-inspired soft robot, which can act as sensors for monitoring pollutants, CO2 levels, temperature and humidity in soil. They were inspired by a South African geranium (a garden plant). The seeds of the plant have the ability to change shape in response to how humid their environment is. When the time comes for the seeds to leave the plant, they can separate themselves from the plant and move independently to find their way through soil. The curly seeds can find a home for themselves simply by becoming bigger or smaller depending on the water content in the air. The team imitated the seeds and developed robots that use materials that also change shape when exposed to humidity. When tested in a soil sample, the robot was able to rock from side to side, adapt its shape to the space, and get into holes in the ground like a natural seed. Not to mention, it was capable of lifting things about 100 times its own weight. First author Luca Cecchini said that the robot is easy to break down and causes no harm to the soil. It could be used as a wireless, battery-free tool for surface soil exploration and monitoring. 语篇解读：本文是一篇说明文。文章介绍的是意大利科学家们开发出了一种受到植物种子启发的软体机器人，可以用作监测土壤中污染物、二氧化碳水平、温度和湿度的传感器。这种机器人易于分解，并不对土壤造成任何伤害，可以用作无线、无需电池的表面土壤探测和监测工具。 √ 1．What can be learned about soil from paragraph 1? A．It is at risk. B．It can be easily polluted. C．It is seldom studied by scientists. D．It is partly responsible for climate problems. 解析：推理判断题。根据第一段第三句可知，由于气候变化导致的气温上升和生物多样性的丧失，我们脚下的土地不断处于危险之中。 √ 2．What is the scientists' purpose of inventing the robot? A．To deal with climate change. B．To improve farming efficiency. C．To monitor the condition of soil. D．To test the 4D-printing technology. 解析：推理判断题。根据第二段最后一句可知，科学家们发明该机器人的目的是监测土壤中污染物、二氧化碳水平、温度和湿度，即检测土壤的状况。 √ 3．What is the basic design feature of the seed-inspired robot?

It uses big tree-planting projects, new farming ways, and strong policies. The most important one is the Great Green Wall, also ____(call) the Three-North Shelter Forest Program. 20 Started in 1978, the Great Green Wall aims to plant many trees in the dry north of China. These trees act like ____(wall). They slow down the wind, stop sandstorms, and hold the soil together. The roots of the trees keep the soil from ____(wash) away, and the trees help the soil slay wet. This makes it possible for more plants to grow. Planting trees isn't ____ only thing China does. It also chooses plants that can live in dry and salty conditions.

Bees collaborate seamlessly to build complex hives, showing the power of unity. The willow sways gently in storms instead of resisting, teaching us to adapt with grace. Even small things hold lessons. A tiny seed pushing through soil reminds us of perseverance, while rivers carving valleys over time tell us patience brings progress. These examples reflect nature's profound understanding of balance. 本课结束 更多精彩内容请登录：www.zghkt.cn $
