作者以前覺得抑郁是自己與生俱來的基因。但有了孩子以后，作者從另一個角度思考人生，每天都積極地尋求積極的一面。4．D[細節(jié)理解題。由文章第一段內容可知，作者經常把自己和別人進行比較。故選D。]5．C[細節(jié)理解題。由文章第三段“Oncewehadkids，myexcuseof‘it's-in-the-genes’didn'tworksowellformeanymorebecausethatmeantmykidswouldbedepressed．AlthoughIrealizedthatstillmightbethecase，Ibeganlookingatmyunhappinessinnewways．”可知，作者對孩子的關心改變了她的想法。故選C。]6．C[推理判斷題。由文章倒數第二段“BecauseIdidn'thavespacetowritealot，itonlytookmeafewseconds．ButinthosesecondsIreplayedmydayanddecidedonitshappiestmoment．”可推知，作者每天都寫日記是為了回憶快樂的時刻。故選C。]7．D[推理判斷題。通讀全文，尤其是由文章最后一段最后兩句可知，文章主要講述了作者以前覺得抑郁是自己與生俱來的基因，但有了孩子以后，作者從另一個角度思考人生，每天都積極地尋求積極的一面。由此推知，這個故事告訴我們——我們應該欣賞生活中光明的一面。故選D。][語篇解讀]本文是一篇說明文。文章介紹了睡眠不足對人的健康產生重大的有害影響，并提倡充足的睡眠。8．B[推理判斷題。根據第一段可推知，作者提到莎士比亞所說的話是為了引出睡眠不足的話題。故選B項。]9．A[細節(jié)理解題。根據第二段中“ApaperpublishedinthejournalHealthPsychologyin2020foundthattheparticipantswithoutenoughsleepexperiencedalesspositivemood．．．”可知，《健康心理學》上的論文告訴我們，睡眠不足讓人們感到消極。故選A項。]10．C[推理判斷題。根據第四段“Someresearchershaveidentifiedlong-timesleepdebtasadisease．．．itseemsreasonabletothinkaboutwhetherthelong-termdeclinesinAmericanhappinessandincreasesinsocialconflictsmaybeconnectedtolossofsleep．”可推知，睡眠不足可能影響個人和社會。故選C項。]11．B[推理判斷題。通讀全文，尤其是最后一段可知，作者寫這篇文章的目的是提倡充足的睡眠。故選B項。][語篇解讀]本文是一篇說明文。新的研究表明：空閑時間不是越多越好，每天兩到三個小時是最理想的空閑時長，且幸福感取決于如何分配這些時間。12．A[詞義猜測題。根據第一段第一句可知，待辦事項過多時，人們會感到不快樂，本句中的轉折說明事與愿違，因而可以推知，時間充足并不是理想的方法，所以推知畫線詞elixir與solution同義。故選A項。]13．B[推理判斷題。根據第四段中的“Forexample，someadultsstrugglewiththe‘retirementblues’，whichcanbeduetolackingstimulationandstructure．”可知，一些人退休后，時間充足反而憂郁了，證明有更多的空閑時間可能是不利的。故選B項。]14．A[推理判斷題。根據倒數第二段中的“Studyparticipantsbelievedtheirwell-beingwouldsufferiftheyhadalotoffreetimeduringtheday—butonlyiftheyuseditunproductively．”可知，如何打發(fā)空閑時間很重要。故選A項。]15．C[標題歸納題。本文主要是關于空閑時間長短的研究，結合第三段中的“Soultimatelythefreetime‘sweetspot’mightbetwotothreehoursperday．”，故選C項。][語篇解讀]本文是一篇說明文。文章介紹了同齡人的力量，青少年可以利用這種社會關系的力量來養(yǎng)成更健康的習慣。16．B[上文“Peopledotendtochoosefriendswhoaresimilartothem．”和“Activitiesincertainbrainareaschangewhenotherpeoplearearound．”講志趣相投的朋友在身邊，你的某些大腦區(qū)域的活動會發(fā)生變化；下文“Youcanusethepowerofsocialrelationshipstogainhealthierhabits—andmotivateotherstodothesame．”講人們可以選擇利用此類社會關系的力量改變自己、于自己有益，B選項“那會影響你的選擇”切合語境。故選B項。]17．D[由下文“Teensareespeciallyresponsivetopeerinfluence．”和常識可知，人敏感是因為在意別人的看法，結合下文出現了“青少年”，該空應該引出各年齡階段都會有因在意別人看法而變得敏感的人的內容，D選項“不同年齡段的人都關心別人的想法”切合語境。故選D項。]18．A[由上文“Aresearchshowsthateve
