Unfortunately，the same technology can also lead to loneliness. Excessive(过多的) screen time，particularly among younger generations，can replace face-to-face exchanges，potentially weakening social skills and deepening loneliness.This is often a point of concern and debate as it is seen to prevent people from experiencing and enjoying the present，physical moment. Another issue that can lead to the division of society is filter bubbles(过滤泡泡).Machine learning used by social media platforms and search engines often shows content that fits a user’s existing thoughts and preferences.Thus people are exposed only to information and opinions that deepen their own views. One more concern for using technology focuses on the user’s privacy.Social media platforms have been offering their services without charge.But in exchange，people are tracked from site to site by technologies such as the cookies，and their personal data can be used to target them with related marketing.As people have become more aware of it，there is increasing potential for people to become more guarded in their online communication，therefore decreasing the development of any sincere online connections. Actually，the impact of technology on human connections is not simply positive or negative.It’s a reflection of how we use the technology.If we are considerate about the way we use technology，we can realize its positive potential for bridging divides and bringing us closer together. 1.What does Julie Morgenstern mainly stress about technology? A.It deepens the existing social gap. B.It helps achieve educational equality. C.It promotes the connection between people. D.It makes information gathering widely easier. √ 推理判断题。根据第一段中的“Anyone can now gain knowledge that several decades ago was only accessible to the highly educated.”可推知，Julie Morgenstern主要强调技术使信息获取更容易。故选D。 解析 2.What does the author think is the influence of filter bubbles on people? A.Narrowing their social circle. B.Strengthening their present belief. C.Exposing them to different thoughts. D.Making them become open-minded. √ 细节理解题。根据第四段中的“Machine learning used by social media platforms...information and opinions that deepen their own views.”可知，社交媒体平台和搜索引擎通常会显示符合用户现有想法和偏好的内容。因此，人们只会接触到加深自己观点的信息，所以过滤泡泡会强化人们现有的观念。故选B。 解析 3.Why do social media platforms offer free services according to paragraph 5? A.To ensure good user experience. B.To promote the use of the Internet. C.To attract potential buyers of goods. D.To encourage online communication. √ 推理判断题。根据第五段中的“But in exchange，people are tracked from site to site by technologies such as the cookies，and their personal data can be used to target them with related marketing.”可知，社交媒体平台提供免费服务，作为交换，人们的个人数据会被cookie等技术跨网站跟踪并用于针对性营销，由此可推知，社交媒体平台之所以提供免费服务是想吸引潜在的商品买家。故选C。 解析 4.What may be the best title of the text? A.Is Excessive Online Time Dangerous? B.How Can We Use Technology Correctly? C.Is Technology Bridging or Dividing Society? D.Are Social Media Privacy Concerns a Major Issue? √ 标题归纳题。通读全文可知，技术弥合了知识鸿沟、使人们联系更密切，但技术也会导致孤独、加深观念分歧或让人变得更警惕。由此可知，文章主要从正反面讲述了技术对人际关系的影响。所以C项(技术为社会架起桥梁还是导致其分裂？)符合文章主旨，适合作标题。故选C。 解析 Ⅵ.完形填空 (2024·湖北荆州高二上期末) I believe joining ASB was one of the best decisions of my eighth-grade year，and being a part of the journalism committee was a wonderful experience.After the first meeting，I had a strong 1 that ASB was going to be a thrill(令人兴奋的经历). 1.A.desire B.intention C.sense D.warning 语篇解读　本文是一篇记叙文。这篇文章主要描述了作者克服了在学校生活中各种活动之间平衡的困难，并对即将到来的高中生活充满期待。 √ desire愿望；intention意图；sense感觉；warning警告。根据下文“ASB was going to be a thrill”可知，作者强烈感觉ASB将是一段令人兴奋的经历。故选C。 解析 The committee was a selected 2 of three students，two of whom were new，including me.So I had to take a 3 course in journalism.Though it sounds challenging，it is easy as long as you use your time 4 . 2.A.class B.community C.group D.band 3.A.cooking B.interviewing C.shopping D.training 4.A.currently B.generously C.individually D.wisely √ √ √ 2.class班级；community社区；group团体；band乐队。根据“The committee was a selected of three students”可知，这个委员会是由三名学生组成的选拔小组。故选C。 3.cooking烹饪；interviewing面试；shopping购物；training培训。根据上文“two of whom were new，including me”可知，组建的委员会是由三个学生组成的选拔小组，其中包括作者在内的两个是新人，因此作者需要参加培训课程。故选D。 4.currently目前；generously慷慨地；individually个别地；wisely明智地。根据上文“it is easy as long as you use your time”并结合语境可知，应是明智地利用时间。故选D。 解析 My first 5 was on ASB’s first event，Spirit Week.I quickly learned that these stories take quite some time and 6 extra time outside of school to be well written.Though I played on a travel hockey(曲棍球) team and had several practices and 7 throughout the week and weekend， 5.A.story B.barrier C.company D.crisis 6.A.balance B.estimate C.manage D.require 7.A.games B.expenses C.destinations D.arrangements √ √ √ 5.story故事，报道；barrier障碍；company公司；crisis危机。根据下文“I quickly learned that these stories take quite some time”可知，作者意识到写这些报道需要相当长的时间，此处是stories的原词复现。故选A。 6.balance平衡；estimate估计；manage管理；require需要。根据下文“extra time outside of school to be well written”可知，这些报道需要额外的课外时间才能写好。故选D。 7.game比赛；expense费用；destination目的地；arrangement安排。根据上文“had several practices”以及下文“travel to practices and games”可知，作者参加了一支旅行曲棍球队，每周有几次训练和比赛。故选A。 解析 some advice I should have taken more seriously was 8 first，fun and games later.I had trouble 9 a consistent schedule throughout the school year，making it 10 to create articles，finish homework，and travel to practices and games.I know now that school should always be the number one priority(优先事项). 8.A.audience B.championship C.school D.wealth 9.A.changing B.keeping C.losing D.adjusting 10.A.tough B.realistic C.necessary D.convenient √ √ √ 8.audience观众；championship锦标赛；school学校；wealth财富。根据下文“I know now that school should always be the number one priority(优先事项).”可知，作者意识到，学校应该永远是第一要务，故作者听从了“先上学，后玩乐”的建议。故选C。 9.change改变；keep保持；lose失去；adjust调整。根据下文“a consistent schedule throughout the school year”可知，在整个学年里，作者很难保持一个连贯的、一致的时间表。故选B。 10.根据上文“I had trouble a consistent schedule throughout the school year”可知，作者在整个学年都很难保持一致的时间表，所以这使得作者很难去写文章、完成作业、旅行训练和比赛。故选A。 解析 My three years at McAuliffe are 11 an end，and though it was quite an experience with 12 schedules，it was an exciting and wild ride， 13 me well for the future. 11.A.giving up B.resulting in C.calling for D.coming to 12.A.tight B.efficient C.perfect D.various 13.A.charging B.exchanging C.preparing D.thanking √ √ √ 11.give up放弃；result in导致；call for呼吁；come to到来。come to an end为固定搭配，意为“结束”。故选D。 12.tight紧的，严密的；efficient高效的；perfect完美的；various各种各样的。根据上文可知，作者上学期间的时间安排非常紧凑。故选A。 13.charge充电；exchange交换；prepare准备；thank感谢。根据下文“well for the future”可知，虽然有着紧凑的时间安排，但这是一次令人兴奋和开心的旅程，为作者未来的发展做好了准备。故选C。 解析 I 14 high school will be quite the experience，with sports，classes，and clubs.It will be exciting because there are so many new things to 15 ，as well as meeting new friends. 14.A.realize B.believe C.imagine D.oppose 15.A.achieve B.explore C.monitor D.display √ √ 14.realize认识到；believe相信；imagine想象；oppose反对。根据下文“high school will be quite the experience，with sports，classes，and clubs”可知，作者相信高中将会是一段很好的经历，有运动、课程和俱乐部。故选B。 15.achieve实现；explore探索；monitor监控；display展示。根据上文“there are so many new things”可知，作者认为有很多新的东西要去探索。故选B。 解析 Ⅶ.语法填空 China is affected by natural disasters easily.
