【易錯警示】解題時,考生很容易誤選A項。文章第二段中多次提到有關“估計”的概念,有的是“高估”,有的是“低估”,還有“精確估計”等,其目的是分析“估計的準確性”,可見本段并不是介紹方法,故排除A項。【考向2】文章大意題【典例展示】(2023·浙江高考·B篇)Livewithroommates?Havefriendsandfamilyaroundyou?Chancesarethatifyou’relookingtoliveamoresustainablelifestyle,noteveryonearoundyouwillbereadytojumponthatbandwagon.

【易錯警示】解題時,考生很容易誤選A項。文章中涉及處理和家庭成員的關系,但是確實是圍繞著文章主題展開的,也就是作者如何讓家人能夠配合過一種零浪費的健康生活,這樣A項明顯是錯誤的,需要排除。【考向3】標題歸納題【典例展示】(2023·新高考Ⅱ卷·B篇)Turningsoil,pullingweeds,andharvestingcabbagesoundliketoughworkformiddleandhighschoolkids.Andatfirstitis,saysAbbyJaramillo,whowithanotherteacherstartedUrbanSprouts,aschoolgardenprogramatfourlowineschools.Theprogramaimstohelpstudentsdevelopscienceskills,environmentalawareness,andhealthylifestyles.Jaramillo’sstudentsliveinneighborhoodswherefreshfoodandgreenspacearenoteasytofindandfastfoodrestaurantsoutnumbergrocerystores.“Thekidsliterallyetoschoolwithbagsofsnacksandlargebottlesofsoftdrinks,”shesays.“Theyetousthinkingvegetablesareawful,dirtisawful,insectsareawful.”Thoughsomeareinitiallyscaredoftheinsectsandturnedoffbythedirt,mostareeagertotrysomethingnew.UrbanSprouts’classes,attwomiddleschoolsandtwohighschools,includehandsonexperimentssuchassoiltesting,flowerandseeddissection,tastingsoffreshordriedproduce,andworkinthegarden.Severaltimesayear,studentscookthevegetablestheygrow,andtheyoccasionallymakesaladsfortheirentireschools.Programevaluationsshowthatkidseatmorevegetablesasaresultoftheclasses.“Wehavestudentswhosaytheywenthomeandtalkedtotheirparentsandnowthey’reeatingdifferently,”Jaramillosays.Sheaddsthattheprogram’sbenefitsgobeyondnutrition.Somestudentsgetsointerestedingardeningthattheybringhomeseedstostarttheirownvegetablegardens.Besides,workinginthegardenseemstohaveacalmingeffectonJaramillo’sspecialeducationstudents,manyofwhomhaveemotionalcontrolissues.“Theygetoutside,”shesays,“andtheyfeelsuccessful.”27.Whatcanbeasuitabletitleforthetext?A.RescuingSchoolGardensB.ExperiencingCountryLifeC.GrowingVegetableLovers D.ChangingLocalLandscape【解題思維】第一步:掃描題干,找關鍵詞。關鍵詞:What,titleforthetext第二步:根據關鍵詞,定位信息。定位原文信息:Theprogramaimstohelpstudentsdevelopscienceskills,environmentalawareness,andhealthylifestyles.(第一段);Jaramillo’sstudentsliveinneighborhoodswherefreshfoodandgreenspacearenoteasytofindandfastfoodrestaurantsoutnumbergrocerystores....(第二段)...Somestudentsgetsointerestedingardeningthattheybringhomeseedstostarttheirownvegetablegardens....(第五段)第三步:根據關鍵詞和定位信息可知,第一段以及下文內容講述了為了培養學生的科學技能、環保意識以及養成健康的生活方式,AbbyJaramillo和另外一位老師在低收入學校發起UrbanSprouts菜園項目,這個項目讓學生體驗菜園生活,對學生影響深遠。因此推斷B項“體驗鄉村生活”符合文意,最適合作為本文標題。故選__B__。

【易錯警示】解題時,考生很容易誤選A項,因為文章中提到thegarden,grocerystores等信息,但是這些信息都是幫助介紹活動內容,文章主旨是介紹“體驗鄉村生活”的情況,故排除A項。【考場技法】技法1段落大意題:“一定、二找、三歸納”技法2文章大意題:“速讀、識別、再總結”技法3標題歸納題:“速瀏覽、定主題、巧概括”【多維演練】Test體裁:說明文詞數:341話題:動物保護建議用時:7分鐘AteamofresearchersfromseveralinstitutionsintheUKandoneinEstoniahascreatedatypeofbuoy(浮標)thathasproventobeeffectiveatfrighteningseabirds,thuspreventingthemfromgettingcaughtingillnets—atypeofverticalfishingnetthatismadeofamaterialthatmakesitnearlyinvisibleunderwater.Everyyear,hundredsofthousandsofseabirdsdiewhentheygetcaughtingillnets.Someestimatessuggestthatuptoahalfmillionbirdsarecaughtinthemeachyear.Overtheyears,researchershavecreateddevicestopreventthebirdsfromtryingtocatchfishnearoringillnets,butthosedidn’tworkwell.Tofindawaythatwouldworkforallseabirds,theresearchersfirststudiedseabirdsinageneralsense,lookingtofindthingsthattheywouldavoid.Theynotedthatseabirdsavoidedeyecontactwithothercreatures.Thentheresearcherscameupwithasimpleidea—theyputasmallpoletoaregularbuoyandthenattachedapairofgooglyeyes(金魚眼)tothetopofit.Theymadetheeyesbigenoughsothatevenbirdswithpooreyesight,suchasgeese,wouldseethem.Addingtotheeffectivenessofthedevice,wavesmadetheeyesmovebackandforth.Andthewindmadethebuoyspinveryslowly,makingsurethatbirdsfromeverydirectionwouldgetagoodlookattheeyes.Totesttheiridea,theresearchersselectedseveralsitesneargillnetsandcountedhowmanybirdsapproachedandhowmanyattemptedtocatchfishnearthenets.Theythensetuptheirgooglyeyedbuoysandonceagaincountedbirds.Overthecourseof62days,theyfoundthenumberofbirdsthattriedtocatchfishnearthegillnetsdroppedbyapproximately25%foradistanc
