These little trash processors(处理器) — some as small as 500 square feet — house a series of machines that recycle waste and transform it into new materials with thermal technology(热技术). The new all-in-one approach could leave our current recycling processes in the dust.In 2018，she launched the first microfactory，establishing a model of recycling that enables businesses and communities to develop commercial opportunities while addressing local waste problems. A second one began recycling plastics in 2019．Now，her lab group is working with university and industry partners to commercialize their patented Microfactory technology. “The small scale of the machines will make it easier for them to one day operate on renewable energy，unlike most large manufacturing plants. The approach will also allow cities to recycle waste into new products on location，avoiding the long，often international，high-emission journeys between recycling processors and manufacturing plants. With a microfactory，gone are the days of needing separate facilities to collect and store materials，extract(提取) elements and produce new products，” says Sahajwalla.Traditionally，recycling plants break down materials for reuse in similar products — like melting down plastic to make more plastic things. Sahajwalla’s invention advances this idea by taking materials from an old product and creating something different. “The kids don’t look like the parents，” she says. Sahajwalla refers to this process as “the fourth R，” adding “ re-form ” to the common phrase “reduce, reuse, recycle”.Professor Veena Sahajwalla’s programs help to develop innovation and promote cooperation with industry，ensuring that sustainable materials and processes become commercially practical solutions for dealing with waste.1．What is the purpose of the first paragraph?A．To introduce a new type of trash processor.B．To introduce the process of recycling waste.C．To prove the seriousness of the trash problem.D．To show the current situation of trash recycling.2．What does the second paragraph mainly talk about?A．The origin of waste microfactories.B．The advantages of waste microfactories.C．The influences of waste microfactories.D．The scale of waste microfactories.3．What does “re-form” in Paragraph 3 refer to according to Sahajwalla?A．Generating new materials with waste.B．Extracting materials from the waste.C．Updating the whole recycling process.D．Transforming waste into same products.4．Where is the text probably taken from?A．A fiction novel. B．A business report.C．A science magazine. D．A chemical textbook.【语篇解读】本文是一篇说明文。文章介绍了Veena Sahajwalla教授曾是澳大利亚的年度人物，她为我们的大规模垃圾问题创造了一个解决方案：垃圾微型工厂。1．A　推理判断题。根据第一段“Professor Veena Sahajwalla, 2022 Australian of the year, has created a solution to our massive trash problem: waste microfactories. These little trash processors(处理器)-some as small as 500 square feet — house a series of machines that recycle waste and transform it into new materials with thermal technology(热技术). The new all-in-one approach could leave our current recycling processes in the dust(Veena Sahajwalla教授是2022年澳大利亚年度人物，她为我们巨大的垃圾问题创造了一个解决方案：垃圾微型工厂。这些小垃圾处理机——有些小到500平方英尺——安装了一系列机器，利用热技术回收垃圾并将其转化为新材料。这种新的一体化的方法可以使我们目前的回收过程望尘莫及). ”可知，第一段的写作目的是为了介绍一种新型的垃圾处理机。故选A项。2．B　段落大意题。根据第二段中的“In 2018, she launched the first microfactory, establishing a model of recycling that enables businesses and communities to develop commercial opportunities while addressing local waste problems(在2018年，她启动了第一家微型工厂，建立了一种回收模式，使企业和社区在解决当地垃圾问题的同时开发商业机会). ”可知，第二段主要谈论了垃圾微工厂的优点。故选B项。3．A　词义猜测题。根据第三段中的“Sahajwalla’s invention advances this idea by taking materials from an old product and creating something different(Sahajwalla的发明通过从旧产品中提取材料，创造出不同的东西，推进了这一想法). ”可知，Sahajwalla将这一过程称为“第四个R”，即在“减少、再利用、再循环”的基础上再加上“重组”。由此可推知，re-form指的是“用垃圾产生新材料”。故选A项。4．C　推理判断题。根据第一段中的“Professor Veena Sahajwalla, 2022 Australian of the year, has created a solution to our massive trash problem: waste microfactories(Veena Sahajwalla教授是2022年澳大利亚年度人物，她为我们巨大的垃圾问题创造了一个解决方案：垃圾微型工厂). ”可知，文章主要介绍了垃圾微型工厂。由此可知，文章可能出自一本科学杂志。故选C项。Ⅱ．读后续写　The Little Boy　A little boy selling magazines for school walked up to a house that people rarely visited. The house was very old and shabby and the owner hardly ever came out. When he did come out, he would not say hello to his neighbours or passers-by but simply just glare at them.The boy knocked on the door and waited, sweating from fear of the old man. The boy’s parents told him to stay away from the house, and a lot of the other neighbourhood children were told the same thing from their parents.Dust found the boy lingering on and hesitating what to do. As he was ready to walk away, the door slowly opened. “What do you want？” the old man said impatiently. The little boy was very afraid, but he had a quota(份额) to meet for school with selling the magazines. So he got up the courage and said, “Uh, sir, I am selling these magazines and uh, I was wondering if you would like to buy one from me. ”　The old man just stared at the boy without a word. The boy could see inside the old man’s house and saw that he had dog figurines(小雕像) on the fireplace mantle. “Do you collect dogs？” The little boy asked. “Yes, I have many collections in my house. They are my family here and they are all I have. ” The boy then felt sorry for the man, as it seemed that he was a very lonely soul.“Well, I do have a magazine here for collectors. It is perfect for you. I also have one about dogs since you like dogs so much. ” The old man was ready to close the door on the boy and said, “No, boy. I don’t need any magazines of any kind, now goodbye. ”　The little boy was sad that he was not going to make his quota with the sale. He was also sad for the old man being so alone in the house that he owned. The boy went home and then had an idea. He had a little dog figurine that he got some years ago from an aunt. The figurine did not mean nearly as much to him since he had a real live dog and a large family.注意：　1．续写词数应为150左右；　2．请按如下格式在相应的位置作答。The little boy headed back down to the old man’s house. ___________________________ _____________________________________________________________　One possible version：　The little boy headed back down to the old man’s house. The thought of knocking at the old man’s door filled the little boy with fear, though, he still knocked on the door, waiting breathlessly. Finally, it opened, and out came the old man. Seeing the boy holding a well-wrapped dog figurine, he looked very astonished but still glared at him without a word. Determined to break the ice, the boy gave the old man the gift with a precious card attached, expressing his care. Deeply moved by all the boy did, the old man could say nothing but to hug him tightly, the tears of appreciation welling up. Out of gratitude, he bought a magazine from the boy and saw him off.From that day on, something changed inside the old man. _____________________________ ___________________________________________________________　One possible version：　From that day on, something changed inside the old man. He adopted a real live dog and treated him as his child. It seemed that it was the company of the dog that led the lonely soul out of darkness and loneliness. Gradually, he was willing to greet others and wear a bright smile, expressing his appreciation to life. Indeed, only when we open up the door of our heart, can we be bathed in the brilliant sunshine and enjoy the warmth of love and care.
