故选C项。湖南省娄底市新化县2021-2022学年高二上学期期末考试英语试题（解析版）【答案】36.E37.C38.B39.G40.D【解析】【分析】这是一篇说明文。友谊是一种非常重要的人际关系，每个人都需要好朋友。良好的友谊有很多好处。它提供友谊，提高自我价值，促进健康。文章介绍了一些如何结交和保持朋友关系的有益建议。【36题详解】根据后文Butformanyofustheprocessisdifficultandrequirescourage.可知但对我们许多人来说，这个过程是困难的，需要勇气。由此可知，后文表示转折，本句则是在说明对有些人来说，结交朋友很容易，但是对许多人来说，这个过程很困难。故E选项“对有些人来说，结交新朋友很容易”符合语境，故选E。【37题详解】根据后文Youcanalwaysstarttheconversation.可知你可以随时开始对话。由此可知，本句是在说明不要等着别人跟你说话，要采取主动。故C选项“不要等着别人跟你说话”符合语境，故选C。【38题详解】本句为本段小标题，根据本段内容Choosingfriendswithcommoninterestsisimportantinbuildingfriendshipastheseinterestswouldalwaysbringyouandyourfriendtogether.Hangingoutwillalwaysbeapleasantexperience.可知选择有共同兴趣的朋友对于建立友谊是很重要的，因为这些兴趣会让你和你的朋友走到一起。出去玩永远是一种愉快的经历。由此可知，本段旨在说明选择一些能够和朋友一起做的事情。故B选项“一起做事”符合小标题，故选B。【39题详解】根据上文However,trynottopressyournewfriendwithcalls,messagesorvisitsasthiswouldlikelywearhimorheroutandfinallyyoumayloseyourfriend.可知但是，尽量不要催促你的新朋友打电话、发信息或拜访他，因为这可能会让他或她筋疲力尽，最终你可能会失去你的朋友。由此可知，本句承接上文说明，不要催你的朋友，要给他们时间来回应你。故G选项“所以你需要给你的朋友时间来回应你”符合语境，故选G。【40题详解】根据后文Trynottochangethemfromwhotheyaretowhatyouwantthemtobe.可知试着不要把他们从本来的样子变成你想要的样子。由此可知，本句旨在说明不要挑剔朋友，接受他们本来的样子。故D选项“尽量不要挑剔你的朋友”符合语境，故选D。湖南省湘潭县2021-2022学年高二上学期期末考试英语试题（解析版）【答案】36.E37.G38.A39.F40.B【解析】【36题详解】本段与下文段落构成总分关系。上文“Dancingisfun,creativeandcanaffectthewayyouthinkandfeel.Whetheryouareastardancerorfindithardtofeelthebeat,movingwithmusiccanbegreatforbothyourbodyandyourmind.(跳舞很有趣，很有创意，还能影响你思考和感受的方式。不管你是明星舞者还是感觉不到节拍，跟着音乐移动对你的身体和大脑都有好处。)”说明跳舞对身心都有益，下文从三个方面进行了分析，此处设空需要承上启下，选项E中的“Thefollowing”引出下文，因此推断E项“如果你还在犹豫，下面的内容可能会引导你进入舞蹈的世界。”符合语境，故选E。【37题详解】由下文的“still”可知，本空与后文“Nowit'sstillabigpartoftraditionsandcelebrationsaroundtheworld(现在，它仍然是世界各地的传统和庆祝活动的重要组成部分)”构成顺承关系，选项G中“formanyyears”和“now”时间上构成先后顺序，因此推断G项“几千年来，人类一直用舞蹈来彼此建立联系。”符合语境，故选G。【38题详解】设空处是段落标题，总领下文。本段的解题关键句为“dancingisgoodforyouinlotsofways(跳舞在很多方面对你有好处)”，剩下的内容“Aswellasbeingagreatwaytoexercise,dancingproducesfeel-goodchemicalsinyourbrain,suchasendorphins（内啡肽）anddopamine（多巴胺）,whichmakeyoufeelenergizedandlessstressed.Italsotunesintoyouremotions,helpingyoutoexpressyourselfandreleaseyourpressure.(跳舞不仅是一种很好的锻炼方式，还能在你的大脑中产生让你感觉良好的化学物质，比如内啡肽和多巴胺，它们让你感到精力充沛，压力减轻。它还能调节你的情绪，帮助你表达自己，释放压力。)”都是对此句进行解释说明，再结合每段分段落开头都是疑问句，因此推断A项“跳舞对你有什么好处呢？”符合语境。故选A。【39题详解】根据下文“ThatiswhyMikePicketsfromRaverTotsCompanypreferstoorganizefestivalsthatbringfamiliestogethertoenjoythemusic.(那就是RaverTotsCompany的MikePickets更喜欢组织家庭聚会来欣赏音乐的原因。)”可知，空处解释下文的原因，对前文“dancingproducesfeel-goodchemicals”和“Italsotunesintoyouremotions”进行总结，得到跳舞比其他活动形式更能让人快乐的结论，因此推断F项“因此比其他任何社交活动跳舞能够带来更多的快乐。”符合语境，这就是人们喜欢组织家庭聚会欣赏音乐的原因，与下文的“thatiswhy”衔接，故选F。【40题详解】B、D项中“Afterthat”与前句“Beforeyoustart”和后面的“Finally”呼应，这里是中间步骤，且观察到“Beforeyoustart”后面是祈使句，选项B、D与句式结构一致，根据下文“Makesureyourepeatanythingthatyoustrugglewithoverandoveragain.(确保你一遍又一遍地重复那些你努力做的事情。)”可知，B项“之后，不断练习你的动作。”符合语境，“keeppracticing”与下文的“repeat”呼应。干扰项D中“controlyourbreathing(控制你的呼吸)”不能承接后文内容。故选B。湖南省岳阳市华容县2021-2022学年高二上学期期末教学质量监测英语试题（解析版）【16~20题答案】【答案】16.E17.A18.G19.D20.B【解析】【分析】本文是一篇记叙文，EwanDrum是一位慈善家，七岁的时候就开始帮助他人，在他人眼里他就是一位超级英雄。【16题详解】根据横线后句“Wearinghisredsuperherocape(斗篷),Ewanhelpedpassout70baglunchestohungrypeopleinaparkinDetroit,Michigan.”可知Ewan把70袋的午餐分发给饥饿的人。这种慈善行为是要事先计划的，E项“Afewmonthslater,Ewan’sfamilyplannedadayofgiving.”符合上下文语境，故选择E项。【17题详解】根据横线后句“Peopledonated(捐赠)moneyandsupplies(供给物),andEwantookthemtothoseinneed.”可知人们捐钱捐物给Ewan，可知他的善良行为被人们所熟知。A项“NewsspreadaboutEwan’sactofkindness.”符合上下文语境，故选择A项。【18题详解】根据横线前句“Anothertime,abusinessmandonatedsixturkeys(火鸡)forThanksgiving.”可知有人捐了六只火鸡，本句应该讲述Ewan如何处理火鸡。G项“Withhisparents’help,EwanaskedformoreturkeysthroughtheInternet,plussidedishes.”讲述的正是此项内容，符合上下文语境，故选择G项。【19题详解】横线前面两句“Youcankeepsomesocksandfoodinyourcartohelppeopleinneed.Youcanhelpaneighborwithdoingthegarden.”所列举的是日常生活中我们可以做的帮助他人的小事，这些微不足道的小事会让别人感觉很幸福。D项“Everylittlethinghelpsandcanmakesomeonefeelhappy.”与语境相符，故选择D项。【20题详解】根据最后一段“Nomatterwhat,”Ewansays,“Iwillalwayskeephelpingpeople.”可知无论发生什么事情，Ewan都会一直坚持帮助他人。B项“Thissuperherosayshe’llnevertakeoffhiscape.”符合上下文语境，故选择B项。【点睛】本文小题2在句首设空，根据后句可知人们捐钱捐物给Ewan，可知他的善良行为被人们所熟知。假如问题出现在段首，它通常是段落主题句。认真阅读后文内容，根据段落一致性原则，查找同义词或其他相关的词，推断出主题句。另外着重阅读后文第一两句，锁定线索信号词，然后在选项中查找相关特征词。通常正确答案的最后一句与空白后的第一句在意思上是紧密衔接的，因此这两句间会有某种的衔接手段，尤其当选项是几句话时。湖南省长沙市宁乡市2021-2022学年高二上学期期末调研考试英语试题（解析版）【16~20题答案】【答案】16.A17.F18.D19.C20.G【解析】【分析】本文是说明文。文章主要通过科学家的研究说明有些人的生活方式，比如他们更喜欢在一天中的什么时间锻炼，以及他们早上醒来有多困难等与他们的“时钟”基因（也被称为PER3基因）有关。【16题详解】上文“Areyousomebodywhocan’twakeupinthemorning?Doyouneedtwocupsofcoffeebeforeyoucanstartanewday?Doyoufeelawfulwhenyoufirstwakeup?Scientistssayit’sallbecauseofourgenes(基因).（你是那种早上起不来的人吗?在开始新的一天之前，你需要喝两杯咖啡吗?当你第一次醒来时，你会感觉很糟糕吗?科学家们说,这都是由于我们的基因）”讲到科学家发现早上起不来或醒来感觉很糟糕等生活方式（习惯），是跟我们的基因有关。下文“ResearchersfromtheUniversityofSurreyinterviewed500people.Theyaskedthemquestionsabouttheirlifestyle,suchaswhattimeofdaytheypreferredtodoexerciseandhowdifficulttheyfoundittowakeupinthemorning.(萨里大学的研究人员采访了500人。研究人员询问了这些人的生活方式，比如他们更喜欢在一天中的什么时间锻炼，以及他们早上醒来有多困难)”讲的是萨里大学的研究人员（科学家们）的研究调查方式。设空处承上启下，说明设空处应是提及了上文的发现（生活方式或习惯是跟我们的基因有关）又提出“如何发现”，才会有下文的解释。A项“Howdidtheyfindthisout?（他们（指科学家）是如何发现这个的呢？）”中的“this”与上文一致，“How”与下文一致，故选A。【17题详解】上文“ResearchersfromtheUniversityofSurreyinterviewed500people.Theyaskedthemquestionsabouttheirlifestyle,suchaswhattimeofdaytheypreferredtodoexerciseandhowdifficulttheyfoundittowakeupinthemorning.(萨里大学的研究人员采访了500人。研究人员询问了这些人的生活方式，比如他们更喜欢在一天中的什么时间锻炼，以及他们早上醒来有多困难)”讲的是萨里大学的研究人员（科学家们）的研究调查方式以及调查的过程，说明设空处应是给出调查研究过程的下一步做法或结果。F项“Scientiststhencomparedtheiranswerstothepeople’sDNA.（然后科学家们将他们的回答与这些人的DNA进行了比较）”中的“thencomparedtheiranswerstothepeople’sDNA.（即调查研究过程的下一步做法）”与上文一致。设空处位于段尾，有承接上文的作用。故选F。【18题详解】上文“Theydiscoveredthatwe
