mails(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 positive 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.”语篇解读　这是一篇说明文。文章向我们说明了计算机分类技术在我们的生活中扮演了至关重要的角色。计算机分类技术可以区分出正面信息和负面信息，从而为我们过滤掉负面信息。 8．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.答案　A解析　细节理解题。由第一段倒数第一句可知，classification boundary是区分正面信息和负面信息的关键。故A选项正确。9．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.答案　D解析　推理判断题。由第二段的第一句可知，这种技术的困难在于它需要正负两方面数据，而在许多情况下我们很难获得负面数据。例如，零售商很难获得从来不在他这儿买东西的顾客的信息。文章举出这个例子是为了解释负面信息很难获得的原因。故D选项正确。10．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.答案　B解析　词义猜测题。由第三段的“...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.”可知，下文中的new method指的是“创建一个信心指数”。故B选项正确。11．What can be a suitable title for the text?A．The History of Classification TechnologyB．Smarter AI：Machine Learning Without Negative DataC．Bigger Data：Computers Assisting Language ProcessingD．The Comparison Between Positive Data and Negative Data答案　B解析　标题归纳题。本文主要讲的是计算机通过学习分类技术可以区分出正面信息和负面信息。并结合第三段末句和第四段的第二句的内容可知，B选项适合作文章标题。D(2021·江苏镇江八校联考)Student loan(贷款) debt has become a worldwide problem.In America，the country’s overall student debt reached a record of $1.6 trillion in 2019.The average person with student loan debt owed between $20,000 and $25,000.A recent Japanese government report says it has been lending over $9 billion yearly to students since 2010.Similar conditions exist in Africa and South America.Several factors account for high student loan debt.One is that employers everywhere have increased their demands for skilled workers，making higher education a requirement for many jobs.The students，however，after graduation，often find that their country’s economy is not strong enough to support their financial needs，so their ability to pay back the loan becomes a problem.To solve the problem，many countries are seeking their ways.Australia has developed a system where students do not have to pay anything back until they are earning at least $40,000 a year.In America，several candidates running for president in the 2020 election have offered more extreme solutions that all or at least some of these loans will be forgiven.Some professors in several universities recently studied what the effects of debt forgiveness might be.They found that，overall，sudden debt relief greatly improved the borrowers’ lives.Not only did they have more money，but they were more likely to move to a new area and seek better paying work.Yet the professors’ research doesn’t include what might happen to financial institutions or the overall economy if debt were totally forgiven.It only looks at how debt forgiveness would help the borrowers.They warn of some other possible negative effects.If a borrower knew that if he ran into any trouble he would be saved because he could get the debt relief，then he might actually become more reckless(轻率的) with his borrowing in the future.No matter what，the professors agree that if countries do decide to approve some student debt relief，the neediest students should be helped first.语篇解读　这是一篇说明文。文章介绍了学生债务已成为全球性问题，对此各国都在寻求解决方案。 12．How does the author introduce the problem of student loan?A．By making a comparison.B．By making classifications.C．By presenting some statistics.D．By setting down general rules.答案　C解析　推理判断题。由第一段的内容可推知，作者通过列举一些统计数据介绍学生贷款的问题。故选C项。13．What can we learn about student loan debt relief?A．It will surely provide some benefits to borrowers.B．It has already been carried out in the United States.C．It aims to encourage more students to borrow money.D．It will prevent a person from landing a well-paying job.答案　A解析　推理判断题。由倒数第三段的最后两句内容可知，债务减免肯定会给借款人带来一些好处。故选A项。14．What is the professors’ attitude to debt forgiveness?A．Uncaring.   B．Positive.C．Disapproving.   D．Cautious.答案　D解析　观点态度题。根据第四段的内容可知，教授们认为免除学生债务是有好处的。再根据第五段可知，他们警告说，还有其他一些可能的负面影响。由此判断出，教授们对债务免除的态度是谨慎的。故选D项。15．What’s the main idea of the text?A．Student loan debt is the most serious problem worldwide.B．Student loan debt tends to pull the needy out of trouble.C．Growing global student debt fuels search for solutions.D．People hold different opinions on debt forgiveness.答案　C解析　主旨大意题。通读全文可知，本文主要介绍了学生债务已成为全球性问题，对此各国都在寻求解决方案。故选C项。Ⅱ.七选五(2021·百师联盟联考)As the coronavirus outbreak continues，many Americans are fearful of using public transportation.They are also looking for ways to get exercise without having to go to a gym，as well as ways to enjoy the outdoors.  1  In the United States，bicycles at big stores like Walmart have sold out.And small bicycle stores cannot keep up with demand for “family-style” bicycles：the low-cost，easy-to-ride models.The bicycle industry is seeing its biggest sales increase since the oil crisis of the 1970s.The increase in bicycle demand began in March as countries began to close down.  2   All bicycle sales，including those for children，are up 100 percent from the year before.  3   Cities like Manila in the Philippines and Rome，Italy have created bicycle paths for the growing number of people who want to avoid public transportation.In London，city officials plan to bar cars from some central roads.Of course，you can only buy a bicycle if you can find one bicycle.In the U．S.，the shortages now mean it may take many months to get one.  4  The U．S.buys 90 percent of its bicycles from China.Bicycle factories there were shut down to stop the spread of COVID-19.In Bar Harbor，Maine，Brian Smith bought a new bicycle for one of his daughters.She is a competitive swimmer who could not get to the pool to practice.His family now goes for rides several times a day.Bicycling helps them all get exercise and enjoy the fresh air.  5  “It’s fun.Maybe that’s the bottom line.It’s really fun to ride bikes，” Smith said.A．But what’s the biggest reason why they go on rides?B．High demand is not the only reason for the shortage.C．Then who has benefited greatest from riding bikes?D．The rise in bicycle sales is not happening just in the United States.E．In April，the sale of bicycles for adults increased 200 percent in the United States.F．However，no bicycles have been imported from abroad like China since the end of last year.G．So，it may not be surprising that the pandemic(流行病) has led to a major increase in bicycle sales.语篇解读　这是一篇议论文。文章指出因为新冠肺炎的传播，许多美国人不敢搭乘公共交通出行，转而选择自行车作为新的出行方式，这一情况导致美国自行车市场紧俏。 1．答案　G解析　本段在描述文章背景，指出人们在寻找户外锻炼的新方式，下文则转入了对自行车相关的描述，G选项“所以，流行病导致自行车销量大增，可能并不让人感到奇怪”贴合给出的背景，且承上启下，引出了后文内容。故选G项。2．答案　E解析　空格前指出随着三月份诸多国家开始封锁，自行车的需求就开始增加。E选项“在四月，美国成年人的自行车销量增加了200%”符合时间顺序，且与后句都可以作为自行车销量增长的数据佐证，符合文意。故选E项。3．答案　D解析　本段列举了菲律宾的马尼拉、意大利的罗马以及伦敦，以说明这些地区的自行车数量都有所增加。D选项“自行车销量增长并不只是发生在美国”适合置于段首，作为本段的主题句。故选D项。4．答案　B解析　空格前句指出在美国自行车货源短缺的情况。B选项“高需求并不是货源短缺的唯一原因”可以自然地引出后文对自行车货源短缺的另一种解释，即因为中国工厂疫情期间的关闭导致断了货源。故选B项。5．答案　A解析　这里空格前句在叙述骑自行车给人们带来的好处。A选项“但他们骑自行车的最大原因是什么呢？”承接前文进行发问，其后则以“It’s
