时事英语阅读理解题 （187）（适合高中）
Chinese scientists say they have developed a robotic fish that can remove microplastic particles(颗粒) from water environments. Researchers working on the project say the robots could help to clean up plastic pollution in oceans around the world. The robotic swimmers are about 1.3 centimeters long. They are made of a soft chemical compound（化合物）. The robots are designed to absorb microplastics while moving through the water. The project was launched（发起） by a team at Sichuan University in southwestern China. The researchers said the robots have already performed well in shallow water and they plan to carry out more tests in deeper waters. The scientists reported their findings in a new study in Nano Letters. The publication（出版物） comes from the American Chemical Society, a nonprofit organization supported by the U.S. Congress. The robotic fish were built to target microplastic particles, which are smaller than five millimeters. Studies have confirmed that microplastic pollution has been discovered in many natural environments. The material comes from the breakdown of manufactured plastic products and industrial waste. The team said the robots can be controlled by light. Turning 'a near-infrared light laser' on and off causes the fish's tail to move back and forth, the American Chemical Society said. The robotic fish can swim up to 2.76 body lengths per second. The researchers said this is faster than most similar soft robots. Wang Yuyan was a member of Wang said similar robots could be developed to be placed inside the human body to remove unwanted materials or disease. (345 words) （注：红色字表示已经在之前的文章中学习过。） 根据文章内容，选择最佳答案： 1.
