Caltech’s scientists have created a special tool for this project.They call it MAPLE.MAPLE and two other devices are part of a project that was sent into space in January, 2023.MAPLE’s job is to test the idea of sending energy wirelessly from space to Earth.We’re used to using wires to move electrical energy from one place to another.But sending energy without wires is a lot trickier. The method used by Caltech’s scientists depends on the way waves act when they meet.Imagine two waves coming together as they travel in the same direction.If the tops of the waves line up, they combine to make a bigger wave.But if the top of one wave lines up with the low point of the other, the waves cancel each other out.The Caltech team has found a way to control the timing of lots of microwaves so that they can combine their power, and focus the energy in one direction.It’s a little like using a magnifying (放大的) glass to focus sunlight into a small, hot point of light. To prove that the system could work, MAPLE sent energy to two devices just 30 centimeters away in space.This energy was then turned into electricity, which made two small lights light up.Next, MAPLE sent energy all the way down to a lab at Caltech.The scientists were able to detect the energy, proving that it’s possible to send solar energy to Earth from space. Dr.Hajimiri, one of the project’s leaders, thinks that one day, the system could be extremely useful, bringing energy to places that need it, all over the world.He believes that in the future, we’ll be able to send energy to remote regions and areas destroyed by war or natural disasters. [语篇解读]　本文是一篇说明文。文章主要介绍了加州理工学院(Caltech)的科学家正在探索从太空中收集阳光并将其能量发送回地球的想法，他们为此创造了一个特殊工具MAPLE，并解释了MAPLE如何通过控制微波的时机来聚焦能量。 1．What is the challenge in Caltech’s project with MAPLE? A．Solar energy detection. B．Wireless energy delivery. C．Sending devices into space. D．Using wires to move electricity. 答案：B 2 3 1 4 解析：细节理解题。根据第二段可知，MAPLE的挑战是无线能量传输。故选B项。 2 3 1 4 2．How does the Caltech team concentrate solar power? A．By changing the way microwaves act. B．By magnifying waves coming together. C．By controlling the timing of microwaves. D．By lining up the waves in opposite directions. 答案：C 2 3 1 4 解析：推理判断题。根据第三段可知，加州理工学院的团队通过控制微波的时间来集中太阳能。故选C项。 2 3 1 4 3．What potential benefit could the system bring in the future according to Dr.Hajimiri? A．Warning people of natural disasters. B．Turning solar energy into electricity. C．Providing a solution to energy shortages. D．Sending energy to regions in urgent need. 答案：D 2 3 1 4 解析：细节理解题。根据最后一段Hajimiri博士的说法，这个系统在未来会向急需能源的地区输送能源。故选D项。 2 3 1 4 4．What can be a suitable title for the text? A．The Use of Solar Energy in Space Exploration B．The Challenges of Generating Energy Without Wires C．The Development of a New Tool for Collecting Electricity D．The Possibility of Sending Energy Wirelessly from Space to Earth 答案：D 2 3 1 4 解析：标题归纳题。本文主要讨论了使用Caltech的科学家创造的特殊工具MAPLE从太空向地球无线传输能源的可能性，所以D项“The Possibility of Sending Energy Wirelessly from Space to Earth (从太空向地球无线传输能量的可能性)”最适合作为本文标题。故选D项。 2 3 1 4 Ⅳ.完形填空 I’m Alina Morse, a fifth grader from Michigan.I always wanted to 1 my own business.Since I was about four years old, I have been writing a journal of business ideas.
