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 the ocean around the world.
The robotic swimmers are about 1.3 centimeters long. They are made of a soft chemical compound. The robots are designed to absorb microplastics while moving through the water. The project was launched by a team at Sichuan University in southwestern China. The researchers said the robots have already performed well in shallow waters 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 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 Sichuan University's research team. She told Reuters news agency that the small, lightweight robot is currently being used to collect microplastics for research purposes. But Wang added that the team plans to expand that use so the robot fish can remove larger amounts of microplastic waste from deep ocean areas. The fish can take in different kinds of microplastics and even repair itself when damaged, the researchers said. And if a robot fish is accidentally eaten by a real fish, it could safely digest the material, the team added. Wang said similar robots could be developed to be placed inside the human body to remove unwanted materials or disease.
1.Why has a robotic fish been created?
A.To remove disease in people. B.To clean up pollution in the ocean.
C.To remove unwanted materials in the body. D.To remove microplastic particles in water.
2.What is paragraph 2 mainly about?
A.The purpose of the robotic fish. B.The function of the robotic fish.
C.A further introduction of the robotic fish. D.Potential application of the robotic fish.
3.What will happen to the robotic fish when eaten by a real fish?
A.It will be harmless. B.It will repair itself.
C.It will take in microplastics. D.It will collect microplastics.
4.What is Wang Yuyan's attitude to the future use of the robotic fish?
A.Pessimistic. B.Positive. C.Unclear. D.Suspicious.

In Broward County, Florida, the school district's cellphone ban has caused strong opposition from both students and parents. Since the beginning of the 2024 school year in August, students in Broward County schools have been banned from using cellphones during school hours, including during lunch and breaks, unless given special permission.
This policy has caused widespread debate, especially as experts highlight the impact of social media and screen time on young people's mental health. Studies have shown a link between social media abuse and increased rates of anxiety and depression among the youth. However, a recent survey done by the school district, which included over 70,000 parents, showed that nearly one in five parents believe the cellphone ban is negatively affecting their children's well-being while one seventh of them think there are no bad effects at all.
One of the main concerns voiced by parents and students is the inability to communicate with family members, especially during emergencies. This is a significant worry in the district that is home to Marjory Stoneman Douglas High School, the site of the 2018 mass shooting that claimed 17 lives. School officials have informed parents that students can still use their phones in emergency situations and that teachers have the flexibility to make phones accessible for other reasons as well.
Many parents and experts argue that phones not only are essential for staying connected but also serve as valuable tools for accessing online lessons and completing assignments, especially for students who lack school-issued laptops. Broward County's school officials have acknowledged the challenges of carrying out the policy effectively. Some teachers have found it difficult to monitor students' phone use, and the policy has raised questions about how to balance the need for phone use with the goal of reducing distractions(使人分心的事).
Landyn Spellberg, a student advisor to the school board, pointed out that phones can offer significant benefits. He emphasized that the district's blanket ban is not solving a key issue: teaching students how to use technology in a healthy way. “We need to educate students about the negative effects of technology, not just forbid its use,” he said.
5.What is the policy of cellphone use in Broward County's schools?
A.The students at school can't use cellphones at will.
B.The teachers are responsible for students' schoolwork.
C.The schools ban students from using cellphones at any time.
D.The parents are not allowed to buy their children cellphones.
6.How many parents think the cellphone ban badly influences their kids' well-being?
A.70,000. B.50,000. C.14,000. D.10,000.
7.What can be concluded from paragraph 3 and paragraph 4?
A.Some bad outcomes might happen for the cellphone ban.
B.Some positive results are spoken highly of by schools.
C.Some teachers think it impossible to monitor cellphone use.
D.Many parents and experts stress the use of cellphones for contact.
8.What will be probably discussed following the last paragraph?
A.The methods of keeping students away from cellphones.
B.The way to teach students to use cellphones wisely.
C.The application of the cellphone ban to more areas.
D.The explanation of negative effects of technology.
