“comfort”

andthen

“comfortanddespair,”

...Iremembered

“Doubt.”

“Peace.”

...Ihaddiscovered...可知，第三段主要讲述了作者从自己所发现的书中学到的东西。26.D。细节理解题。根据最后一段中的WhenIwenttocollege,Bartlett'scamewithme...tothisdayIoftenrefertoit可知，作者上大学后一直保存着在地板下发现的那本书，常常翻阅它，由此可知，作者很珍视这本书。27.C。写作目的题。结合全文可知，作者写此文是为了讲述她从阁楼地板下发现了一本书之后，从书中得到启迪，并开始爱上读书，从而改变人生的故事。C篇主题语境：人与社会——科学与技术本文是新闻报道。AI

船长“重走”“五月花号”路线！无人驾驶船将横跨大西洋。28.B。细节理解题。根据第二段中的Itwillcrosstheseapoweredbysunandwind,andcontrolledbyartificialintelligence(AI)可知，新型“五月花号”动力为清洁能源。29.C。推理判断题。根据第三段中的showedthat

“thepioneeringspiritoftheMayflowerreallyliveson”.

“We'reheadingoutwiththesamespiritofadventureanddeterminationandhopeforthefuture...”可知，新型“五月花号”代表的是人类无畏的探索精神。30.B。细节理解题。根据第四段中的WampanoagstorieshavebeenmarginalizedonpastMayfloweranniversaries,buttheyareplayingabigpartineventsandexhibitionsthistimearound可知，万帕诺亚格人的故事在以往的纪念活动中无人问津，而在这次“五月花号”的纪念活动中将扮演重大的角色。31.B。推理判断题。根据最后一段中的itstrans-Atlantictriptomeasureoceanhealth:assessingtheimpactofclimatechange,measuringmicro
