主谓一致主谓一致是指主语和谓语要保持人称和数的一致，英语中的主谓一致主要遵循三个原则：语法一致原则、意义一致原则和就近一致原则。这三个原则常常发生矛盾，但当发生冲突时，意义一致原则为优先考虑的原则。意clothing，furniture，traffic，jewelry，baggage，equipment，luggage等不可数名词Clothingisbadlyneededinthisfloodedarea.以s结尾的表示学科、国家、机构、书籍、报刊等Politicsisoftenatopicfordiscussion.语法一致原则单数Heistalkingwithhisbrother.复数Theboysareplayingfootball.就近一致原则由or/either...or.../neither...nor.../notonly...but(also)...等连接与最近的主语在单复数上保持一致①EitherIortheyareresponsiblefortheresultofthematter.②NeitherInorheisinfavourofhermarriage.由there，here引起的主语不止一个时和最邻近的主语保持一致Thereisapen，aknifeandseveralbooksonthedesk.义一致原则名称的词单数表示时间、重量、距离、价格、金钱、体积等复数名词表达一个整体概念Fortymileswascoveredinasinglenight.由every，any，some，no和one，thing，body等构成的不定代词Iseverybodyheretoday?动词ing形式、动词不定式和名词性从句①Persuadinghimtojoinusseemsreallyhard.②Whateverwasleftwastakenaway.意义一致原则由连词and连接的并列成分指的是同一概念，兼具身份或匹配出现单数Warandpeaceisa①constantthemeinhistory.Thesingeranddanceristo②attendoureveningparty.no/each/every/manya＋单数名词＋and(＋Manyateacherand(manya)no/each/every/manya)＋单数名词studenthasseenthefilm.one/everyone/each/either/thenumber＋of/thevarietyof＋复数名词Thenumberofstudentsfromthenorthissmall.意义一致原则由and连接两个并列成分表不同概念复数Steamandicearedifferentformsofwater.一些常用复数或只有复数形式的名词如arms，stairs，goods等。Thegoodsaresoldout.以s结尾的专有名词如山脉、运动会、群岛等。TheOlympicGamesareheldonceeveryfouryears.anumberof＋名词AnumberofstudentsarefromChina.特别由两部分构成的表示物体的名词，如trousers，pants，①Yourglassesareverynice.提醒jeans，compasses(圆规)，glasses，shorts等作主语时，谓语动词常用复数形式。但如果这类名词前用了apairof或two/three...pairsof来修饰，谓语动词在数上要与pair保持一致。例句②Thispairofglassesismine.③Herearesomenewpairsofshoes.“名词＋with，alongwith，togetherwith，aswellas，ratherthan，asmuchas，but，except等＋名词”结构作主语时，谓语动词的单复数形式要与第一个名词保持一致。Tomaswellas①twoofhisfriendswasinvitedtotheparty.②Dr.Smith,togetherwithhiswife,istoarriveontheeveningflight.aquantityof后既可接复数名词，亦可接不可数名词。如果aquantityof接不可数名词，则谓语动词用单数形式；如果接复数名词，则谓语动词通常要采用复数形式(※偶尔谓语动词用单数，属非规范用法，宜慎用)。quantitiesof后接复数名词、不可数名词，后面的谓语动词都用复数形式。①Thereisasmallquantityofwaterleftinthebottle.②Alargequantityofbooksareonsalenow.③Greatquantitiesoffishwerecaughtthatday.若用and连接两个动名词、不定式短语或主语从句，表示两个不同的概念则谓语动词用复数形式。若表示同一概念，则谓语动词用单数形式①Ridingontheelephantsandrowingtheboatswerethechildren'sfavoritegames.①Whathesaysanddoesdonotagree.②Whathesaysanddoesdoesnotconcernme.what和whatever引导主语从句时谓语动词的单复数根据从句所表达的意义上的数确定练习：用括号内所给词的适当形式填空1.AteacherofEnglishandclassteacher________(tell)ussomethingaboutvolunteerworkersnow.2.Whenandwherethistookplace________(be)stillunknown.3.Everymeans________(try)，butnoneprovedsuccessful.4.WeiboaswellasWeChat________(serve)asamediaplatformforpeopletosharetheirthoughtsinstantlywithoutlimitsofplaceortime.5...
