Unit2Peopleonthemove语法段落基本要素练习好的文章有一些主要的构成要素，段落就是其中之一。段落是用来在散文、故事或其他文章中组织信息的。在写段落时，我们通常包括以下内容：1.主题句每个段落都应有一个要点，该要点通常由主题句表达。主题句应清楚地陈述本段落的信息。整个段落都围绕主题句展开。例如：Youngadultsgivemanydifferentreasonsformovingtocities.不过也并不是所有的段落都有主题句的。比如有时一个段落延续了前一个段落的主题，而前一个段落有主题句的情况下，这个段落就不一定有主题句了。主题句通常是段落的第一句。不过在散文、故事或其他一些文体的第一段中，主题句可以置于一段引子之后。为了吸引读者的注意力，我们可以使用一段引子。这个引子常常是一个有趣的事实、一个问题或一段引语。例如：OlderAmericansareonthemove.2.支撑句主题句后应跟有对其加以解释或证明的支撑句。例如：Fordecades,Floridahasbeenattractingolderresidents.Infact,accordingtothenationalpopulationsurveyconductedin2000,Floridawashometothelargestpopulationofpeopleaged65andolder.段落中的支撑句的排列顺序是有逻辑的。我们可以使用过渡的词语将每句句子与其前后的句子连接。可使用的过渡词语包括forexample,forinstance,furthermore,first,second,third,ontheotherhand,however,but和also。Floridaisapopularchoiceforthesepeoplebecauseoftheclimateandthestate’srelativelyflatlandscape.However,asthenumberofolderAmericansmovingthereincreases,morechangesaremadetocatertothem.Forexample,ambulanceresponsetimehasbeendecreased,andmanyhouseshavebathroomsdesignedforelderlyhomeowners,withthingslikewalk-inbathtubsthatreducetheriskofslipsandfalls.3.结论句段落应以一句用新的方式重复主题句内容的句子结尾。当然了，结论句不是主题句的简单重复，而是对它的扩展与总结。有时也可以用结论句来表达关于这个主题的最后想法，或用它来帮助引入下一段的主题。第1页共5页2024-12-18AcrosstheUSA,peoplearenoticingthesamething:youngpeoplewanttoliveincities.4.注意与中文不同，英文段落中的“主题句——支撑句——结论句”的结构一般情况下是很明确的。而中文段落的主题句可能出现在段首、段中或段末。这是中西文的不同之处。练习：一、选出下列各段落的主题句。A.Oneofthereasonsforvisitingthelighthousesisthatthelighthouseshaveaprofoundhistoryandprovideagoodviewofnature.B.Visitinglighthouseswillhelpustounderstandthelivesoflighthousekeepers.C.Anotherreasonforconsideringavisitisthatthelighthousesthemselvescanbeveryattractivebuildings.D.Themostimportantreasonforsuchavisitistorealizehowourancestorsbattlednaturewiththebasictoolstheyhad.Everyoneshouldvisitalighthouseatleastonce.(1)__________Theyhadonlybasicwaysofcreatinglight,andyettheyfoundawayofusingthissimpletechnologyinisolated(孤零零的)placestosaveshipsfromhittingrocks.(2)__________Bytheirverynature,lighthouseswerebuiltonsomerocksorcliffs.Thusthelighthousekeepersoftenlivedlonelylives.Towalkaroundtheirsmallhome,andimaginetheangrystormoutsidebeatingagainstthewalls,istotakeasteptowardsunderstandingthelivestheyhad.(3)__________Thereasonforavisittoalighthouseisnotallsobackward-lookingintime.Itistruethatlighthouseswerebuiltinout-of-wayplaces.Butonapleasantsunnysummerday,thisveryisolationhasanaturalbeautythatmanypeoplewilllovetoexperience.Therefore,withthegentlewavestouchingallroundthelighthouse,thevisitorislikelytothinkitisaworldpreferabletothebusyandnoisymodernlife.第2页共5页2024-12-18(4)__________Mankindcouldoftennotbecontentjusttoputupabasicstructure,butfelttheneed,eveninsuchanisolatedplace,tobuildwithanartistictouch.Theresultisaviewfortiredeyestoenjoy.Finally,lighthouseshavea...
