DIn the United States,nearly 15%of the 92 million tons of clothing and other textiles arerecycled annually,meaning that about 17 million tons of textiles are sentto landfills each year.Much of the problem lies inth fact tha reeyer have a hard time knowing what xathe item is made of,and thus,these mountains of textiles are incredibly difficult to sort.Tagsare often cut off or washed,and printed information can wear off.Missing or inaccurateknowledge about an item's fiber composition can make textile recycling cost-prohibitive.)Good news is that a University of Michigan-led team has developed woven-in labels madewith inexpensive photonic fibers(光子纤维)，which ensure that the materials used in clothescan be easily identified."It's like a barcode that's woven directly into the fabric of clothes,"said Max Shtein,a University of Michigan professor."We can customize the photonicproperties of the fibers to make them visible to the naked eye,readable only under near-infrared(近红外)light or any combination.”A similar concept is already in use by recyclers for some materials.Recyclers already usenear-infrared sorting systems that identify different materials according to their naturallyoccurring optical (signatures.The PET plastic in a water bottle,for example,looksdifferent under near-infrared light than the HDPE plastic in a milk jug.Like different plastics,different fabrics also have unique optical signatures.But as Brian lezzi,lead author of thestudy,explains,those signatures don't help recyclers much because so many fabrics arecomprised of a mix of materials."Fora truly iru reydlingymtowork.its important to know the precisecomposition of a fabrica cotton recycler doesn't want to pay for a piece of clothing that'smade of 70%polyester,"lezzi said."Natural optical signatures can't provide that level of线precision,but our photonic fibers can."As electronic devices like cell phones develop,they could potentially have the ability toread this kind of photonic labeling,"Shtein said."So I could imagine a future where woven-inlabels are a useful feature for consumers as well as recyclers.32.What is the challengen textile recvcling in the US?A.The poor quality in old clothes.B.The difficulty in sorting textilesC.The high cost of collecting textiles.D.The lack of drop-off sites for clothes.33.What can we infer about the newly eveloped label?A.It is hard to weaeff.B.It looks like a barcode.C.It is invisible the naked eye.D.It contains more textile fibers.英语卷（二）第7页（共12页【24·(新高考)ZX,MN·英语·N)
