Now, the AI system (系统) in reserves plays an important role in studying wildlife. Instead of using binoculars (望远镜), people can 1 animals’ activities on big screens. The AI system can be very 2 . First, it can recognize different animals by their tails, feet, or beaks and 3 their numbers. Second, it can record animals’ actions all day and night, which humans couldn’t do before. It also notices unusual behaviors. For example, if an animal moves 4 or lies still for too long, the system will 5 researchers to help quickly. Besides, it keeps unauthorized (未经许可) people out of protected areas and teaches visitors about wildlife. But there are still 6 to be solved. For example, sometimes the AI system mixes up one animal with another. It might mistake plants for animals and provides 7 information for researchers. Also, because the system isn’t used everywhere in reserves, people still need to 8 some areas themselves. To improve the AI system, nature reserves are working with high-tech companies to make the system better and cover more 9 . Although the AI system isn’t 10 , it works faster and protects animals more effectively (有效地) than old tools. Most importantly, it helps keep the natural ecosystem in balance. 1．A．keep B．support C．watch D．lead 2．A．helpful B．central C．local D．direct 3．A．add B．count C．solve D．reduce 4．A．loudly B．widely C．luckily D．strangely 5．A．punish B．warn C．influence D．remain 6．A．surprises B．changes C．secrets D．problems 7．A．wrong B．similar C．valuable D．correct 8．A．check B．fill C．leave D．build 9．A．trades B．dates C．areas D．standards 10．A．modern B．perfect C．convenient D．useful 【答案】 1．C 2．A 3．B 4．D 5．B 6．D 7．A 8．A 9．C 10．B 【导语】本文是一篇说明文，主要介绍了自然保护区中AI系统在野生动物研究中的作用、优势以及目前存在的问题。 1．句意：人们可以在大屏幕上观看动物的活动。 keep保持；support支持；watch观看；lead领导。根据“Instead of using binoculars, people can…animals’ activities on big screens”可知，此处指通过大屏幕“观看”动物活动，替代望远镜的功能。故选C。 2．句意：AI系统非常有帮助。 helpful有帮助的；central中心的；local当地的；direct直接的。根据后文列举的AI系统功能可知，它很有帮助，故选A。 3．句意：首先，它可以通过尾巴、脚或喙识别不同动物，并数它们的数量。 add增加；count计数；solve解决；reduce减少。根据“recognize different animals…and…their numbers”可知，AI系统能识别动物并“统计”数量。故选B。 4．句意：比如，如果动物移动得奇怪或躺太久不动，系统会提醒研究人员迅速提供帮助。 loudly大声地；widely广泛地；luckily幸运地；strangely奇怪地。根据“unusual behaviors”可知，此处指动物行为异常，strangely符合语境。故选D。 5．句意：比如，如果动物移动得奇怪或躺太久不动，系统会提醒研究人员迅速提供帮助。 punish惩罚；warn警告；influence影响；remain保持。根据“help quickly”可知，系统会“提醒”研究人员，故选B。 6．句意：但仍有一些问题需要解决。 surprises惊喜；changes变化；secrets秘密；problems问题。根据后文“For example, sometimes the AI system mixes up one animal with another.”可知，需要解决的是问题。故选D。 7．句意：系统可能将植物误认为动物，为研究人员提供错误信息。 wrong错误的；similar相似的；valuable有价值的；correct正确的。根据“mistake plants for animals”可知，系统会提供“错误的”信息。故选A。 8．句意：此外，由于该系统并没有在保护区的所有地方使用，人们仍然需要自己检查一些地区。 check检查；fill填充；leave离开；build建造。根据“the system isn’t used everywhere”可知，未被覆盖的区域需人工“检查”。故选A。 9．句意：保护区正与高科技公司合作，扩大系统覆盖的区域。 trades贸易；dates日期；areas区域；standards标准。根据“cover more…”可知，目标是扩大系统覆盖的“区域”。故选C。 10．句意：尽管AI系统并不完美，它比旧工具工作更快，更有效地保护动物。 modern现代的；perfect完美的；convenient方便的；useful有用的。根据前文提到的问题（如识别错误）可知，系统尚不“完美”。故选B。 根据短文内容，从A、B、C、D四个选项中选出一个能填入相应空格的最佳答案。 Waste sorting (grouping) began on July 1, 2019.

We believed they would finally change their 7 . Six months later, we finally made it. People in my building had begun sorting their waste. Some even 8 us to sort waste that was sorted improperly. I think face-to-face talks played an important 9 . Sometimes, these talks cause arguments, but they worked much 10 than just leaving messages or handing out papers.

But the farmers who owned the forest 2 trees every year until one year, there were no trees left. One day, our teacher took us out and we had a 3 in the field where the forest used to be. While eating and drinking, we talked about the beautiful forest we once had. One of my classmates came from a village in the west of our country. 4 told us what he thought about the change. “It makes me really 5 to learn that a forest has disappeared. My parents have taught me to 6 think about seven generations (七代人) in the future. That’s to say, when we do something to the land, we should never hurt it. We must care about nature and leave it good enough 7 next generations.” When we heard 8 he said, we kept silent first. “Let’s plant some trees!” said our teacher after a moment. “It will be a good 9 !” So that’s what we did. For the rest of that spring, we worked hard and we planted thousands of trees. That was five years ago. Today, when I stand in that field which was once empty, I see trees as tall as I am.

Why did Sweden make such an 2 ? Like many other countries, Sweden was once a land with much trash 3 the government decided to clean it up. Then trash sorting took top priority (优先). The Swedish government believed that children 4 the idea of trash sorting from an early age, so it became a part of the national education. 5 were given the knowledge in the school, and then taught their parents at home. After the efforts, the rules of trash sorting have 6 become part of Swedes’ daily life. Many Swedish neighborhoods have central collection stations, from which pipelines run through walls and into the ground, connecting different kinds of rubbish bins. The bin has a sensor. Once the bin is 7 , it opens itself, and the rubbish, driven by strong winds, rushes to the central collection station at a 8 of 70 km/h. Rubbish collection is done 9 a clean way. Right now, you and your family may face the difficulty of sorting out the rubbish. 10 if we can really see the advantages—a beautiful picture like Sweden, pains are worthwhile. 1．A．high B．low C．big D．small 2．A．agreement B．achievement C．experiment D．argument 3．A．after B．before C．if D．because 4．A．should tell B．should be taught C．can be told D．must ask 5．A．Children B．Girls C．Boys D．People 6．A．hardly B．never C．already D．yet 7．A．empty B．dirty C．filled D．ugly 8．A．height B．weight C．length D．speed 9．A．in B．by C．from D．to 10．A．But B．So C．Although D．Unless Nature reserves (保护区) provide the best home for wild animals with warm weather, water, plants and wetlands. Now, the AI system (系统) in reserves plays an important role in studying wildlife. Instead of using binoculars (望远镜), people can 1 animals’ activities on big screens. The AI system can be very 2 . First, it can recognize different animals by their tails, feet, or beaks and 3 their numbers. Second, it can record animals’ actions all day and night, which humans couldn’t do before. It also notices unusual behaviors. For example, if an animal moves 4 or lies still for too long, the system will 5 researchers to help quickly. Besides, it keeps unauthorized (未经许可) people out of protected areas and teaches visitors about wildlife. But there are still 6 to be solved. For example, sometimes the AI system mixes up one animal with another. It might mistake plants for animals and provides 7 information for researchers. Also, because the system isn’t used everywhere in reserves, people still need to 8 some areas themselves. To improve the AI system, nature reserves are working with high-tech companies to make the system better and cover more 9 . Although the AI system isn’t 10 , it works faster and protects animals more effectively (有效地) than old tools. Most importantly, it helps keep the natural ecosystem in balance. 1．A．keep B．support C．watch D．lead 2．A．helpful B．central C．local D．direct 3．A．add B．count C．solve D．reduce 4．A．loudly B．widely C．luckily D．strangely 5．A．punish B．warn C．influence D．remain 6．A．surprises B．changes C．secrets D．problems 7．A．wrong B．similar C．valuable D．correct 8．A．check B．fill C．leave D．build 9．A．trades B．dates C．areas D．standards 10．A．modern B．perfect C．convenient D．useful 根据短文内容，从A、B、C、D四个选项中选出一个能填入相应空格的最佳答案。 Waste sorting (grouping) began on July 1, 2019.

Several of us were not sure 3 we could lead people in the building to change their habits or not. We began with the usual ways. We posted notices around the neighborhood. We also went door to door, 4 information about it. But they still made lots of mistakes. For example, man didn’t know what waste meant food waste. 5 , they thought it meant waste that was wet. Some even refused to sort their waste. We went around explaining the rules. We also let them know we had grouped their waste for 6 . It was a matter of time and patience (耐心). We believed they would finally change their 7 . Six months later, we finally made it. People in my building had begun sorting their waste. Some even 8 us to sort waste that was sorted improperly.

More than 1 meter in height, the 1 are usually full after no more than half a day. I know that many of the things 2 end up in the bins, including vegetable leaves and food that is left, have a completely 3 ending in many cities. When I was at school, my mother 4 these things to feed our chickens, pigs, cats and dogs. The animals’ excrement (粪便) was used to make the land that produced our food rich. However, some of my neighbors 5 recyclable waste and even pollute the environment, making much of the garbage unsuitable for recycling. I often think: What can be done to reduce the 6 , at least in my own home? Baidu, a popular website, did offer me a(n) 7 : a compost (堆肥) tumbler (滚筒). Such a thing can help change kitchen waste into fertilizer (肥料). I couldn’t wait to start trying it last summer, 8 as there is a large piece of land with little vegetation near my home. On March 17, the day after my son’s third birthday, my wife and I 9 to use the thing we made last year to plant some flowers. We also collected dog excrement, which we buried (埋) in the area we chose for the flower. We named it “Our Beautiful Home Plan” and would like to make it a long-term 10 activity.

But one day, one of the drops got bored with his clean 2 . He wanted to see what would be like to be a dirty drop. The other drops told him to 3 the idea, but he didn’t listen. When the drop came back all dirty, he turned all the other drops in the bottle into dirty drops, too. They 4 to get clean again, but couldn’t. Several months later, someone put the large bottle in a fountain (喷泉). A lot of clean water entered the large 5 , and the drops in it finally became cleaner. Now the drops all know that if they want to be clean, then each one of them will have to stay clean. Correcting the mistake of even one single drop 6 a lot of hard work. To some degree, this bottle of water is just like the 7 . If we want to live on a clean planet, each one of us will have to be a “clean drop”. Whenever someone or some country becomes a “dirty drop” and 8 the air or the sea, the whole earth will become a bit dirtier. It will be very 9 , perhaps even impossible, to make “bottle of water” clean again. It’s the same for your 10 . If you want your class to be among the best, then each of you will need to do well.

There are fewer places for some animals to live in than before.” “What can we do?” asked Juliet sadly. “I’m sure you will 6 of something,” said her mom. When they got to the park, Juliet painted a picture of the park and wrote a 7 in big letters at the top of the picture. The sign read “PLEASE KEEP OUR PARK CLEAN”. She put up her picture on a big rubbish can and got some gloves from their car. “Will you help me pick up 8 , Mom?” Juliet asked. “I surely will,” replied her mom. Soon, Juliet’s friends also arrived. Juliet 9 them each a pair of gloves. “Let’s clean this place up,” said Juliet. Then they began this clean-up, talking and laughing.

It was a sunny Saturday morning, and we 1 to make our community more beautiful. We brought gloves, bags, and a strong 2 to help. As we started, I noticed an old man sitting on a bench, watching us quietly. He seemed 3 at first, but after a while, he slowly walked towards us and asked if he could 4 . We gladly agreed. He introduced himself as Mr. Chen, a retired (退休的) teacher who had 5 in this neighborhood for over thirty years. While picking up plastic bottles and paper, Mr. Chen shared stories about how the park used to be a place of natural 6 . Children came to fly kites and 7 the fresh air. But now, pollution had made it less enjoyable. He said, “In the past, children loved playing here, but now they 8 come because of the trash (垃圾).” His words made us realize the importance of our work. We worked for hours, and 9 , the park became cleaner. Mr. Chen’s smile grew brighter as he saw the changes. He even started to water some young trees we brought to plant. “These will provide shade (阴凉) in the future,” he said happily. By the afternoon, we had 10 over ten bags of trash. Mr. Chen thanked us and said, “Your kindness 11 me that there is still hope for our community.” We felt proud and promised to 12 this activity every month. Just as we were leaving, a woman from a nearby house came out with a camera. She said she had 13 our whole effort and wanted to post (发布) it online to encourage others. We were surprised but 14 . A few days later, we saw her video on the Internet, and many people in the community said that they would join us next time. That day, I learned that a small action can make a big 15 .

For the first time, the 1 clearly calls on countries to move away from using fossil fuels (石化燃料) to create energy. 2 many people say the agreement doesn’t go far enough to protect the planet (行星) from global warming. The agreement was 3 at COP28 the United Nations climate meeting in Dubai. United Ara Emirates. Representatives (代表) 4 nearly 200 countries took part in the meeting. The 5 was to reach agreements that will help slow global warming. One of the big questions about COP28 was whether countries would agree to stop producing fossil fuels (called a “phase-out”), or would simply agree to produce less (called a “phase-down”) Over 100 countries, 6 the United States and the European Union, were pushing for a phase-out. But countries like Saudi Arabia and India 7 this idea. These countries either depend heavily on fossil fuels, or on the money they 8 by selling them. Because of this disagreement, the final deal doesn’t mention a phase-out or a phase-down. 9 , it calls for “transitioning (转型) away from fossil fuels”. That’s a huge 10 to many people who had hoped for a stronger position. But it’s also the first time a COP meeting has 11 moving away from fossil fuels. The agreement calls for a huge 12 in clean energy. Around 130 countries have 13 to produce three times as much renewable energy by 2030. Representatives from small island countries are especially 14 that the COP28 agreement did not call for a phase-out of fossil fuels. These countries say the agreement 15 to solve the climate crisis quickly enough. They believe this puts their nations at risk (危险) from rising sea levels. 1．A．agreement B．plan C．idea D．custom 2．A．If B．But C．And D．Although 3．A．reached B．carried C．cut D．listed 4．A．for B．with C．from D．at 5．A．goal B．result C．dream D．course 6．A．including B．except C．for D．with 7．A．depended on B．fought against C．hoped for D．looked up 8．A．buy B．make C．find D．discover 9．A．Instead B．Suddenly C．Luckily D．Happily 10．A．kindness B．disappointment C．development D．chance 11．A．enjoyed B．minded C．mentioned D．escaped 12．A．increase B．encouragement C．fall D．price 13．A．promised B．refused C．asked D．answered 14．A．excited B．surprised C．interested D．angry 15．A．succeeds B．fails C．suggests D．allows 学科网（北京）股份有限公司 $
