19、villages with unique architecture.BA simple project to help a family in need stopped Luke Mickelson in his tracks. 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
20、 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.Bom and raised in Idaho, Mickelson, now 41, had a thriving career. He coached his kidssports teams and fished in the nearby river. But when he met
21、children who were sleeping on thefloor, his peaceful life changed course.Using safety guidelines and his daughters 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 holidays. As word spread, in
22、terest and involvement from his and other communities floodedalong with Mickelsons 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 ou
23、r town, the nonprofit and its more than 65 branches have built and delivered more than 1, 500 free beds to children across America. Butalong 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 great money to

27、 tallest in the world, towered above Hannah Ginffiths and her colleagues each morning as they walked deep into the rainforest in the Maliau Basin in Bomeo, 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
28、 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 carton-rich materials. A whole industry is aiming at ki
29、lling 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 h fallenmaterial under control and letting nutrients from the dead material back into the system to be used by other p
30、lants, insects, and animals. But they didnt know exactly how important the insects were in keeping the forest healthy and functional, so whey remove 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 experim
31、ent when the forest was hit by an extreme drought (干旱). During the non-drought years, they saw therewasnt much difference between the normal plots and the ones where theyd removed thetermites. But during the drought, the effects were marked. What they found was unexpected: inthe termite-rich areas,
32、the soil stayed slightly wet, more tree seedlings sprouted (抽芽), and thesystem 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 termites to the system, she points out. And that
33、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 dont know what that will do.”28.

35、 can we infer from the finding of Griffiths experiment?

37、spam mail（垃圾邮件）， false political newsWhen we use AI, such tasks are based on “classificationtechnology” in machine earninghaving 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 t
38、hat include a sad face. Once a classification boundary is learned,thecomputer can determine whether a certain data is positive or negative.However, the difficulty with his technology is that it requires both positive and negative data for the learning process, and negative data are not available in
39、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 d
40、o not have access to their competitors data.According to lend author Takashi Ishida from RIKEN AIP, “Previous classification methodscould not cope with the situation where negative data were not available, but we have made itpossible for computers to learn with only positive data, as long as we have
41、 a confidence score for our positive data, constructed from information such as buying intention or the active rate of appusers. Using our new method, we can let computers learn a classifier only from positive data equipped with confidence.”According to Ishida. “This discovery could expand the range
42、 of applications whereclassification technology can be used. Even in fields where machine learning has been activelyused, 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
43、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
44、regularly. C.By separating happy faces and sad ones. D.By introducing classification technology.33. Why is the example mentioned in Paragraph 2?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 expl
45、ain 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?

But indeed it takes effort to build them successfully. 36 Thus, when the big ones come, we will have developed the patience we need for hard times.Understand the addictive nature of anger and impatience.
