主谓一致tbetweensubject1. 主谓一致是指主语和谓语要保持人称和数上的一致，主语的“人称”和“数”决定谓语动词的变化。如：(1) Iam(be)fifteen.Sheis(be)sixteen.Andhowoldare(be)you?(2) Thereis(be)adeskintheroom.Thereare(be)nochairsinit.(3) Jimgets(get)upatsixo'clockeverymorning.(4) Theyhave(has/have)notcomeyet.Whathas(has/have)happenedtothem?(5) Nobodyknows(know)whois(be)goingtowininthecompetition.(6) Whatis(be)thelatestnewsabouttheWorldCup?如果主语不是单一的，或主语名词的数比较特殊时，则主谓一致一般要依据语法一致、意义一致、就近一致的原则来判断。2. 集体或集合名词作主语时，遵循意义一致原则：如果强调整体，谓语动词用单数；如果强调个体(成员)时,谓语动词则用复数。这一类常见的集合名词有group，class,family,team,crowd,army,enemy,police,couple,audience,government,population,thepublic等。另外，集合名词 people,cattle 作主语时，谓语动词用复数。如：(1) Thefamilyis(be)verybig.(2) Thefamilyare(be)veryearlyrisers.(3) Thisclasshas(have)eighteengirlsandtwenty-fourboys.(4) Thisclassare(be)verybrightespeciallyinsciencesubjects.(5) Thegovernmentwere(be)havinganimportantconferencewhenIgotthere.(6) Thegovernmentis(be)planningfurthercutsinincometax.(7) Thearmyis(is/are)goingtoremaininthistown.(8) Thearmyhave(has/have)rescuedtheminerstrappedundertheruins.(9) Thepoliceis(be)anorganizationwhichprotects(protect)thepublicfromharm.(10) Thepoliceare(be)peoplewhocatch(catch)thievesandburglars.(11) Thecouplewere/was(be)marriedin2009.(12) Theaudienceseem/seems(seem)tohaveenjoyedtheconcert.(13) Thepublicare/is(be)veryexcitednowthattheconcerthalliscompleted.(14) ThepopulationofChinais(be)verylargeandmorethanhalfofthepopulationlive(live)inruralareas.(15) Inthedistance,peopleare(is/are)workinginthefieldandcattleare(is/are)grazing(吃草)onthehillside.3. 某些单复数同形的名词如 means,species,series,sheep,deer,fish 等作主语时，谓语动词的单复数可根据名词前的修饰语、限定词或上下文来判定。如：(1) Everymeanshas(has/have)/Allmeanshave(has/have)beentried,butinvain.(2) Thereis(is/are)anews...
