30.What does the research show about children?A.They care less about their appearance than before.B.They are more willing to seek help in public.They prefer helping others to being helped.D.They tend to ask for assistance in private.31.What can people do to remove children's reputation-based barriers?A.Value children's efforts to get help.BExpose children to various social risks.C.Point out children's errors in the conversation.D.Create opportunities for children to seek help openly.DFrom airplanes to apartments,most spaces are now designed with sound-absorbing mate-rials that help decrease various sounds of everyday life.But most of the sound-absorbing ma-terials that can cancel out human voices,traffic noise and music are made from plastic foams(that aren't easily recyeled or degraded.Now,researchers reporting in ACS Sustain-able Chemistry Engineering have created a biodegradable film (obtained from sea-weed.which effectively absorbs sounds in this range.Controlling and optimizing the way sound moves throughout a room is key to creatingfunctional spaces.Foam sound-absorbing panels are a common solution,and they come in avariety of materials and thicknesses tailored to specific sound requirements.Most of thesefoams,however,are made from a type of plastic material and other chemical substances thatare obtained from natural oil or petrol.To avoid petrochemicals,researchers have exploredmore renewable sources and biodegradable sound-absorbing alternatives.But many currentoptions are made from plant fibers that don't effectively decrease noises in the most usefulrange of sound frequencies.or they are too thick or difficult to produce.So,Chindam's teamwanted to develop a biodegradable material from a plant,which would be simple to produceand could absorb a range of sounds.The team created films of agar(),a material that comes from seaweed,along withother additives developed from plants and varied the thickness of the films.After running thematerials through a battery of tests,the researchers measured how well the films reducedsound across a range of frequencies.To do this.the team created a sound tube in which aspeaker is placed at one end,and the test film is fitted over the other end.Microphones in themiddle of the tube measured the amount of sound sent by the speaker and the amount of soundreflected off the film.These experiments showed that the films with many small holes madewith the highest concentrations of agar had the greatest sound-absorbing qualities andperformed similarly to traditional sound-absorbing foams.The researehers plan to exploreways to change the agar films to give them other desirable properties,such as flame resistance.and will explore other biologically obtained film materials.32.What is the disadvantage of plastic foams?A.They take up too much space.B.They cannot absorb many sounds effectively.【高三英语第6页（共10页）】·23-35C·
