AYou might have heard a lot about ancient towns and ancient cities in China. Here, we list several of the most beautiful ancient villages in China.Baoshan Stone City, Yunnan ProvinceBaoshan Stone City was built on a huge mushroom-shaped rock, and only has about one hundred houses.

In 2012, he and his family were inspired to build and donate a bunk bed, one bed on top of the other, after learning there were local children who slept on the floor. Shocked to discover how widespread this need was in his community, Mickelson founded Sleep in Heavenly Peace, a nonprofit that builds and delivers beds to children in need.Born and raised in Idaho, Mickelson, now 41, had a thriving career. He coached his kids’ sports teams and fished in the nearby river. But when he met children who were sleeping on the floor, his peaceful life changed course.Using safety guidelines and his daughter’s bunk bed as a model, Mickelson started buying wood and supplies to build beds with his own money. He recruited friends and family members to help around the holiday. As word spread, interest and involvement from his and other communities flooded—along with Mickelson’s bunk bed output. “That first project, we built 11 bunk beds in my garage,” he said. “The next year, we did 15. Then it doubled every year. In 2017, we built 612 bunk beds.”With the motto “No kid sleeps on the floor in our town”, the nonprofit and its mor e than 65 branches have built and delivered more than 1,500 free beds to children across America. But along with the rapid growth, Mickelson was faced with a tough choice: advancing his career or his nonprofit. He chose the latter and went from making “gre atmoney to zero money”. He’s never looked back. “I found that the need I have isn’t financial,” he said. “The need I have is seeing the joy on kids’ faces, knowing that I can make a difference.”24. Why did Mickelson set up Sleep in Heavenly Peace?A. To help the poor children.B. To make a big fortune.C. To inspire his community.D. To get more donations.25. What do we know about Luke Mickelson?A. He had his own fish farm.B. He changed his career from time to time.C. He used to sleep on the floor when he was a kid.D. He originally had a relaxing and pleasant life.26. How did other people react to Mickelson’s project?A. They showed little interest in it.B. They were supportive and involved in it.C. They were doubtful about the safety of the bunk bed.D. They volunteered to buy beds with their own money.27. What is Mickelson’s attitude to the nonprofit?A. AmbiguousB. Defensive.C. Cautious.D. Positive.CTrees, some of the tallest in the world, towered above Hannah Griffiths and her colleagues each morning as they walked deep into the rainforest in the Maliau Basin in Borneo, where they had set up a set of experiments to look at the ecological effects of small creatures: termites (白蚁).Termites get a bum rap. They make headlines for chewing up billions of dollars of property each year in the U. S. And they are responsible for something like two percent of global carbon emissions, simply as a result of their huge populations and preference for chewing through carbonrich materials. A whole industry is aiming at killing them.But they play a key role in many natural ecosystems. Scientists have known for years that in tropical (热带的) forests, termites chew up fallen leaves and dead wood, keeping the fallen material under control and letting nutrients from the dead material back into the system to be used by other plants, insects, and animals. But they didn’t know exactly how important the insects were in keeping the forest healthy and functional, so they removed termites from a particular spot in the forest and saw how it responded.As luck would have it, Hannah Griffiths and her colleagues started their experiment when the forest was hit by an extreme drought (干旱). During the non-drought years, they saw there wasn’t much difference between the normal plots and the ones where they’d removed the termites. But during the drought, the effects were marked. What they found was unexpected: in the termite-rich areas, the soil stayed slightly wet, more tree seedlings sprouted (抽芽), and the system was full of activity despite the long, hard dry spell.For Griffiths, it was only because they happened to study the drought that they could pick out the real importance of termi tes to the system, she points out. “And that rings alarm bells in my head,” she says, “because it makes me think, well what else don’t we know? If we start damaging biological communities, we don’t know what that will do.”28. Which of the following best e xplains “a bum rap” underlined in Paragraph 2?A. Unfair blame.B. Wide popularity.C. Public attention.D. Special preference.9. What have scientists learned about termites?A. They do serious harm to tropical rainforests.B. They contribute a lot to the ecosystem they live in.C. They act as food for other plants, insects and animals.D. They speed up the loss of nutrition in the rainforest.30. What can we infer from the finding of Griffiths experiment?A. Termites help rainforests survive climate change.B. Termites prefer drought years to non-drought ones.C. Termites benefit more from the forest during the drought.D. Termites enjoy eating tree seedlings during the drought.31. What does Griffiths tell us in the last paragraph?A. Termites are now in danger of extinction.B. Termites damage biological communities.C. We should think twice before damaging a species.D. We should study the drought to improve the system.DClassifying things is critical for our daily lives. For example, we have to detect spam mail (垃圾邮件), false political news. When we use AI, such tasks are based on “classification technology” in machine learning—having the computer learn, using the boundary separating positive and negative data. For example, “positive” data would be photos including a happy face, and “negative” data photos that include a sad face. Once a classification boundary is learned, the computer can determine whether a certain data is positive or negative.However, the difficulty with this technology is that it requires both positive and negative data for the learning process, and negative data are not available in many cases. For instance, when a retailer (零售商) is trying to predict who will make a purchase, they can easily find data on customers who have purchased from them (positive data), but it is basically impossible to obtain data on customers who have never purchased from them (negative data), since they do not have access to their competitors’ data.According to lead author Takashi Ishida from RIKEN AIP, “Previous classification methods could not cope with the. situation where negative data were not available, but we have made it possible for computers to learn with only positive data, as long as we have a confidence score for our positive data, constructed from information such as buying intention or the active rate of app users. Using our new method, we can let computers learn a classifier only from p ositive data equipped with confidence.”According to Ishida, “This discovery could expand the range of applications where classification technology can be used. Even in fields where machine learning has been actively used, our classification technology could be used in new situations where only positive data can be gathered due to data regulation or business constraints (限制). In the near future, we hope to put our technology to use in various research fields, such as natural language processing, computer vision, robotics, and bioinformatics.”32. How can the computer distinguish the positive data from the negative data?A. By learning the classification boundary.B. By updating the data collected regularly.C. By separating happy faces and sad ones.D. By introducing classification technology.33. Why is the example mentioned in Paragraph 2?A. To prove how important the positive data are.B. To confirm that data on customers are complete.C. To argue that retailers get their competitors’ data.D. To explain why negative data are hard to acquire.34. What do the underlined words “new method” in Paragraph 3 refer to?A. Analyzing buying intention.B. Building a confidence score.C. Assessing the active rate of app users.D. Equipping the computer with confidence.35. What can be a suitable title for the text?A. The History of Classification TechnologyB. Smarter AI: Machine Leaning without Negative DataC. Bigger Data: Computers Assisting Language ProcessingD. The Comparison between Positive Data and Negative Data第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
