53、reasing the number of them. The growing number of cyclists, however, brings this question to mind: should bicyclists be required to share the responsibilities of the road? Automobile drivers have to take competency tests, follow established regulations, and accept punishment for breaking rules. The

54、city requests drivers to register and license their vehicles to ensure accountability (责任）. Bicyclists who use public roadways should be held accountable, too.Lets look at what sharing the road means. For one thing, it should involve cost sharing.Auto registration and license fees are used, in part,

55、 for building and maintaining roadways. It seems only reasonable to ask bicyclists to contribute to transportation funding as well.More importantly,sharing the road includes accountability. When drivers ignore the rules of the road, the police and other motorists have the opportunity to identify the

56、m by their license plate number and report their offenses (违法行为）。 This isnt true for bicyclists. Ive seen bicyclists moving quickly between lanes.Because they show no identification, they feel protected by anonymity(匿名）。What good would it do to report to the police “I saw a guy on a red bike blow th

57、rough the stoplight? The simple act of making bicyclists identifiable would encourage safer, more responsible riding.Of course,Ive heard arguments against asking cyclists to register and license their bikes. Some people might say, “Little kids ride bikes. Would you require a six-year-old rider to ta

58、ke a test and pay a fee? Obviously, the city could determine an age when cycling would be considered a means of transportation on public roads. Other people argue that bicycle fees are unfair because bikes dont damage the roadways as cars do. Bicycle registration fees could be comparatively modest,

59、and the method for displaying a license number could be simple.Many U.S. cities and towns now implement bike registration and licensing. A statute(法规）from one. California town states that the laws regulating bicycles have a dual purpose, antitheft and safety. Im eager to see more bicyclists on the r

60、oad, and Im hoping for riders who take their responsibilities seriously.28. To advocate responsible cycling, the author suggestsA. increasing the number of bike lanesB. giving competency tests to all cyclistsC. identifying cyclists through registrationD. reporting cycling offenses more frequently29.

61、 What is the authors purpose in writing Paragraph 4?A. To explain how bicycle registration and licensing work.B. To provide solutions to reduce irresponsible cycling of kids.C.

64、es to ensure accountability (责任）. Bicyclists who use public roadways should be held accountable, too.”可知，市政府要求司机登记并给他们的车辆上牌，以确保责任追究。骑自行车的人使用公共道路也应承担责任。由此可知，作者建议通过登记识别骑车人。故选C。【29题详解】推理判断题。根据第四段“ Some people might say, “Little kids ride bikes. Would you require a six-year-old rider to take a test and

65、pay a fee? Obviously, the city could determine an age when cycling would be considered a means of transportation on public roads. Other people argue that bicycle fees are unfair because bikes dont damage the roadways as cars do. Bicycle registration fees could be comparatively modest, and the method

66、 for displaying a license number could be simple.”（。有些人可能会说，“小孩子骑自行车。你会要求一个6岁的骑手参加考试并支付费用吗？”很明显，这个城市可以确定一个年龄，自行车将被视为“公共道路上的交通工具”。其他人认为自行车收费不公平，因为自行车不会像汽车那样损坏道路。自行车登记费可以相对较低，显示牌照号码的方法也可以很简单。）可知，作者描述第四段的目的是回应人们对骑自行车者问责的质疑。故选C。【30题详解】推理判断题。阅读第一段“The city requests drivers to register and license their v

67、ehicles to ensure accountability (责任）. Bicyclists who use public roadways should be held accountable, too.（市政府要求司机登记并给他们的车辆上牌，以确保责任追究。骑自行车的人使用公共道路也应承担责任。）”可知， 此处作者通过将汽车和自行车进行对比来支持自己的观点；根据最后一段“Many U.S. cities and towns now implement bike registration and licensing.（许多美国城市和乡镇现在实施自行车登记和发放牌照。）可知，作者也通过具

68、体的例子来支持自己的观点。由此可知，作者在本文通过举例子和作比较的方式来支持自己的论点。故选D。【31题详解】主旨大意题。阅读文章内容，并根据第一段“The growing number of cyclists, however, brings this question to mind: should bicyclists be required to share the responsibilities of the road? ”可知，越来越多的骑自行车的人提出了这样一个问题:骑自行车的人应该分担道路责任吗?由此可知，本文主要讲述骑自行车的人是否应该注册并给他们的自行车颁发牌照。所以短文

69、的最佳标题为“骑自行车的人应该注册并给他们的自行车颁发牌照吗”。故选B。DAlzheimers AIAn estimated 5.7 million people in the U.S. have Alzheimers disease-the most common type of dementia(痴呆）and that number is expected to more than double by 2050. Early diagnosis is crucial for patients to benefit from the few therapies available. But

70、no scans can deliver a conclusive diagnosis while a person is alive; instead doctors have to conduct numerous and complicated clinical and neuropsychological tests.So there is growing interest in developing artificial intelligence to identify Alzheimers based on brain imaging.Researchers at the Univ

72、n nearly all the test cases, according to the study. In PET imaging, a very small amount of a radioactive compound are injected into the body, producing three-dimensional images of metabolism(新陈代谢）,circulation and other cellular activities. PET is well suited for an AI diagnostic tool because Alzhei

These changes are very hard for radiologists to pick up,he notes.The algorithm was trained and tested on 2,100 PET brain ima

74、ges from about 1,000 people 55 years and older. The images came from a 12-year study that tracked people who would ultimately be diagnosed with Alzheimers, as well as those with mild memory declines and healthy control participants. The algorithm was trained on 90 percent of the data and tested on t

The algorithm was highly sensitive and was able to recognize 81 percent of the patients in the first test group and 100 percent in the second who would be diagnosed with Alzheimer

76、s six years later, on average. The findings were published in February in Radiology.The algorithm is based on deep learning ,a machine-learning technique that uses artificial neural networks programmed to learn from examples. This is one of the first promising,preliminary(初步的） applications of deep l

G【解析】这是一篇议论文。文章讨论了“管理孩子们的屏幕时间是个好主意吗”这一问题，最后得出结论：父母应该让孩子们有发言权，让他们参与问题的计划和决策过程。【36题详解】由上一句“在今天家庭中，屏幕时间是一个重要的话题，特别是在疫情流行期间，许多学生的在线教育时间成倍增加。”和下一句“他们希望让孩子们免受科技带来的无数挑战。”可知，疫情流行期间，学生上网面对屏

96、幕的时间增加，家长害怕这样对孩子造成不好的影响，所以会去购买相关的程序工具来监控孩子的上网时间，控制孩子们的屏幕时间，该选项中的“manage childrens screen time”对应本段尾句中的“managing screen time”，承接上下文，E选项“为了管理孩子们的屏幕时间，家长们投资了应用程序和追踪器。”切题。故选E项。【37题详解】由下一句“但是科技也有积极的好处。”可知，But表转折，空后说科技的好处，此空应说科技不好的地方，比如不健康的网站对孩子不好，承接下文，A选项“当然，有些网站对孩子来说是不健康的。”切题。故选A项。【38题详解】由上一句“这是个神话，认为父母

97、可以或应该通过专制的限制来管理孩子的荧屏时间，甚至在小学阶段也是如此。”和下一句“当孩子们被排除在这些决定之外时，他们通常会减少与父母和兄弟姐妹的交流。”可知，对于管理孩子们的屏幕时间，父母专制型的监管很难实现，而且当孩子被排除在“屏幕时间管理”的决定外，又会带来消极影响，说明作者认为孩子应该参与到“屏幕时间管理”的决策中，该选项中的“decisions”对应下文中的“those decisions”，承接上下文，B选项“另一种选择是让孩子们参与决定屏幕时间。”切题。故选B项。【39题详解】由下两句“从很小的时候起，孩子们就很有能力理解良好的生活需要意识和平衡。正如他们从错误中学习正确，从错误

98、中学习好，他们也可以学习以健康的方式使用技术。”可知，孩子有能力理解一些事物，也能学习各种使用技术，说明孩子是有自主（学习）意识的，所以让孩子参与到“屏幕时间管理”的决策中时，父母要信任孩子有自我意识去学习、理解事物，承接下文，F选项“为了让孩子参与进来，父母应该信任并培养孩子的自我意识。”切题。故选F项。【40题详解】由上一句“明确地说，这篇文章并不是建议家庭永远不要使用应用程序或追踪器，或者不应该限制屏幕时间。”和下一句“父母应该让孩子们有发言权，让他们参与计划和决策过程。”可知，文章并非不建议父母不去管理孩子的屏幕时间，而是建议父母让孩子也参与到“屏幕时间管理”的决策中，相对于父母专制型
