本文从以下几个角度介绍。

A.expected to offer helpB.enjoying others'serviceC.caught borrowing moneyD.suffering a little bad luck26.What's the tone of the passage?A.Serious.B.Humorous.C.Cautious.D.Anxious.27.Which of the following is a suitable title for the passage?A.I'm a NobodyB.There Is Nowhere to HideC.Am I a Reliable Friend?D.Has Anybody Seen Me Lately?CChinese scientists have developed a fish-shaped light-actuated(光驱动的)swimming robotthat can "eat"microplastics in water bodies and repair itself if damagedMicroplastics,pieces of plastic smaller than 5 millimeters,are numerous and widelydistributed in the ocean.They are easily eaten by marine organisms(海洋生物)and transmittedthrough the food chain,presenting a serious threat to human and ecosystem health.Inspired by nacre,also known as mother of pearl,a strong,durable and flexible materialobtained from hard shells,scientists from Sichuan University modeled nacre's graphene-basedgradient nanostructure(石墨烯基梯度纳米结构)to create a durable,flexible and self-repairingnanocomposite(纳米复合材料)，according to a study published in the journal Nano Letters.The research team then used the new material to develop a 15-mm fish-like soft robot,enabling it to swim rapidly and absorb microplastics in water."Soft robots need to have highadaptability and environmental tolerance when working in complex water environments,"saidWang Yuyan,the first author of the research paper,who added that existing traditional soft robotsare generally made of rubber,which poorly performed in mechanical capacity,easily damagedand have difficulty integrating (functions.The study showed that compared with traditional uniformly dispersed(均匀分散的)material structures,the new material used in the fish-shaped soft robot has many supramolecular(interactions between layers,allowing the robot to recover its stability and functionalityeven when damaged and continue its microplastic harvesting operations.The robotic fish can swim at a speed of 2.67 times its body length per second,exceedingthe speeds of previously reported soft swimmers and comparable to the speed of other smallforms of plant and animal life that live in water.At present,the soft robot can only achieve the function of directionally collectingmicroplastics from the water surface.All these functions need to be developed and improvedbefore large-scale application.The researchers are currently working on a new material that could detect microplasticunderwater and share live data online,the paper said.The new nanostructural design is expected to offer an effective extended path to otherintegrated robots and to be applied in many fields such as solar power generation,chemicalreaction catalysis(催化)，bio-medicine and aerospace高一英语第5页共11
