（2022·沈阳高三教学质量监测）The world produces around 359 million tons of plastics each year.Plastics are certainly a big problem，but they don't necessarily have to be.There are many ways we could set plastics on a different lifecycle.One that I have been working on is turning plastics into hard，reliable and sustainable building materials.
Most people believe that plastic recycling is severely limited：Only a few types can be recycled.This is unsurprising.The proportion（比例）of plastics that are recycled is minimal.But all polymers（聚合物）are，technologically，recyclable.Some of them can be used again and again to produce the same goods.Some can technically be reprocessed into new materials for different applications.
The problem is that recycling much of this plastic waste is currently unprofitable.But the amount of these materials all over the world is large and keeps on growing.What if this plastic waste could be used to produce something useful to the society？Many universities and business people are attempting to do this.Most solutions target mixed plastic waste and suggest applications different from the original ones.For example，several groups have developed building materials made of plastic waste.Plastics are strong，durable，waterproof，lightweight and recyclable—all key properties for construction materials.So what if all of this plastic waste could be turned into building materials for lowincome populations？Existing initiatives are promising，but not yet reproducible on an industrial scale.
I study plastic waste with the aim of finding interesting ways to remove it from the environment.From agricultural waste to concrete waste，mixed with recycled plastics，there are many ways to obtain materials to produce bricks and other useful elements for buildings.So perhaps plastics are not necessarily the problem.They can be part of a pathway towards a more sustainable way of living.
【语篇解读】 本文是一篇说明文。主要说明了全球每年产生大量的塑料垃圾，如何回收利用这些垃圾成了人们思考的问题。
1.What's people's common belief about plastic recycling？
A.Almost all plastic waste can be reused.
B.The methods are quite limited.
C.Not many kinds of plastics are recyclable.
D.The amount of plastics is unbelievably large.
解析：细节理解题。根据第二段第一句“Most people believe...be recycled”可知，大多数人认为塑料回收受到严格限制：只有几种类型的塑料可以回收。
答案：C
2.What can be learned from Paragraph 3？
A.Plastic waste is on the decline globally.
B.Recycling plastics doesn't make money now.
C.Plastic buildings have been largely constructed.
D.New applications of plastics haven't been found.
解析：细节理解题。根据第三段第一句“The problem is...currently unprofitable”可知，回收塑料垃圾目前是无利可图的。
答案：B
3.Why can plastics make good building materials？
A.They can resist water and won't last long.
B.They can be reproduced in large quantity.
C.They satisfy the needs of lowincome people.
D.They meet most demands of building materials.
解析：细节理解题。根据第三段第七句“Plastics are strong...for construction materials”可知，塑料的坚固、耐用、防水、轻便、可回收等特性满足建筑材料的要求。
答案：D
4.What's the author's attitude to plastic recycling？
A.Positive. B.Anxious.
C.Doubtful. D.Critical.
解析：推理判断题。根据尾段最后三句“From agricultural waste...way of living”可知，将农业废料和混凝土废料与回收塑料混合可以生产很多有用的建筑材料；或许塑料未必是问题，而是可持续的生活方式的一部分。据此可知，作者对塑料回收持积极的态度。
答案：A
