D.How Harvard Shapes My Teenage YearsODo you prefer to watch TV or listen to the radio?There was a time when some peoplethought moving pictures beamed live into our houses would spell the end of tuning in to theradio for entertainment and information.But radio survived and flourished.And now,despitethe growth in sophisticated smartphones offering high-definition pictures,the popularity ofpodcasts(播客)is booming.Perhaps the growth in podcasting is not surprising-it offers a digital audio file that canbe downloaded and stored for listening at any time.It can also be streamed from the Internetand played on a computer or MP3 player.And it's not just broadcasters,like the BBC,who areproducing podcasts:now commercial broadcasters,individuals and companies with noconnection to broadcasting are making them.In fact,anyone with something to say,and a fewpounds to spend on the equipment,can get involved.But where did this trend for making portable audio programmers begin?Journalist BenHammersley told the BBC that"two changes transformed the market-one cultural and onetechnical".Apple launched the iPhone podcast app,recording and editing equipment becamecheaper,and 4G mobile phone connections and Wi-Fi became widespread.Technological development has driven many changes in our media consumption habits.But however good the tech may be,there still needs to be something worth watching orlistening to.The BBC's Jamie Robertson writes that for podcasts,Serial-a piece ofnon-fiction investigative journalism-captured people's imagination.It was a piece ofhigh-quality audio with a gripping story.To date,the first and second seasons of the show havehad more than 340 million downloads.Advertisers soon realized the money-making potentialof this and other successful podcasts.Now there are podcasts about anything and everything-even the educational contentthat BBC Learning English offers!And these aural treats are available on a wide range ofplatforms.Audiences are very specific,which can help advertisers target what they want topromote.28.What can be done with a digital audio file?A.It can be played without power.B.It can be used to make phone calls.C.It can offer high-definition pictures.D.It can be downloaded and stored for listening at any time.29.Why is it easy for almost anyone to make a podcast?A.The cost of making a blog is low.B.It can be streamed from the Internet.C.It can be played on a computer or MP3 player.
给老年人提供娱乐，从而有益于促进他们的身心健康。29.A。理解具体信息。根据第三段中的Fishing is a pastime that brings back memories..Live fishenables those suffering from all levels of dementia to feel as though they are a part of the bigworld outside可知，钓鱼能唤起痴呆患者的记忆，并让他们感觉自己是世界的一部分。30.D。理解具体信息。根据第四段中的The contest highlighted how nursing homes,,assistedliving communities,hospitals and adult day care centers have responded to the challenges whilestill trying to provide high-quality services to residents可知，该比赛旨在褒扬养老院、辅助生活机构、医院和成人日托中心在困难境遇中仍试图为服务对象提供高质量服务的行为。31.B。理解主旨要义。文章主要讲述了一家老年护理中心在极端天气情况下，为了给老年护理对象提供有益身心的娱乐活动而设计了一款钓鱼推车，并获得了国际大奖。B项作标题最能概括本文主旨。【词汇链接】on top of(the last para.):除…之外D篇主题语境：人与社会一一人际沟通本文是说明文。研究表明，在网络社交中，人们会用表情符号来表达或者掩饰自己的真实情感。32.C。理解具体信息。根据第一段中的display rules can promote interpersonal harmony可知，遵守表达规则有助于建立和谐的人际关系。C项中的maintain positive relationships是promoteinterpersonal harmony的同义转换表达。33.A。推断。根据第四段中的Respondents expressed least emotion towards individuals whohold a higher social position可知，研究参与者在与比自己地位高的人交流时，不大可能会表现出自己的情绪。题干中的leaders是individuals who hold a higher social position中的一种。结合第二段中的to investigate how emojis were used to express or mask emotions可知，该研究调查如何用表情符号来表达或掩饰情绪。由此可推知，在与领导进行网络交际时，研究参与者最有可能做的事情是不表达自己的情绪，即不使用任何表情符号。34.C。理解具体信息。根据最后一段可知，由于研究参与者都是Simeji键盘的使用者，而该键盘特别受年轻女性的欢迎，因此目前该研究的样本偏向女性和Z世代。更广泛的参与者有助于研究者更全面地了解表情符号的表达规则。也就是说，该研究的参与者数据样本应该扩大。35.D。理解主旨要义。本文主要介绍了一项关于表情符号的研究。第一段中的scientists areinvestigating how emojis are used to reflect our emotions in different contexts.Are there displayrules that apply to emojis,and how do those affect people'swel-being揭示了该研究的目的。第四段陈述了该研究的结果：在不同的社交场合中，人们会使用表情符号来表达或掩饰自己的情绪；与掩饰情绪相比，用表情符号表达情绪与更高的主观幸福感相关。D项最能概括本文主旨。第二节主题语境：人与社会一一历史、社会与文化本文是说明文。文章讲述了在旅行中参观博物馆的益处。36.A。设空处为本段小标题，所填内容应能概括本段内容。本段主要讲述了在旅行中逛博物馆能学到很多知识。A项“逛博物馆是有教育意义的”能概括段落内容，其中的educational在本段得到复现。37.G。设空处上一句谈到“在博物馆你会找到有相同兴趣的人”，设空处下文谈到“你们不仅可以分享很多兴趣爱好，而且到访博物馆的每个人都是为了相同的原因：学和玩。当
