Therebe句型的用法一、构成:Therebe...句型表示的是“某处有(存在)某人或某物”,其结构为Therebe(is,are,was,were)+名词+地点状语。例如:1)Therearefifty-twostudentsinourclass.2)Thereisapencilinmypencil-case.3)Therewasanoldhousebytheriverfiveyearsago.二、各种句式:否定句:在be后加上“not”,也可用“no”来表示。即:no+n.(名词)=nota\an\any+n.(名词)。例如:1)Thereisanorangeinherbag.→Thereisn’tanorangeinherbag.→Thereisnoorangeinherbag.2)Therearesomeorangesinherbag.→Therearen’tanyorangesinherbag.→Therearenoorangesinherbag.3)Thereissomejuiceinthebottle.→Thereisn’tanyjuiceinthebottle.→Thereisnojuiceinthebottle.一般疑问句:Therebe结构的一般疑问句变化只需把be动词移到句首,再在句尾加上问号即可。例如:4)Thereissomemoneyinherhandbag.→Isthereanymoneyinherhandbag?(疑问句和否定句中,some改为any,something改为anything.)5)Thereissomethingnewintoday’snewspaper.→Isthereanythingnewintoday’snewspaper?特殊疑问句:Therebe句型的特殊疑问句有以下三种形式①对主语提问:当主语是人时,用“Who’s+介词短语?”;当主语是物时,用“What’s+介词短语?”。其中there在口语中常常省略。注意:无论原句的主语是单数还是复数,对其提问时一般都用be的单数形式(回答时却要根据实际情况来决定)。如:6)Thereisabirdinthetree.→What’sinthetree?7)Therearesomebikesoverthere.→What’soverthere?8)Thereisalittlegirlintheroom.→Whoisintheroom?②对地点状语提问:用“Whereis\are+主语?”表示(注意其答语变化):例如:9)Thereisacomputerinmyoffice.→Whereisthecomputer?----It’sinmyoffice.10)Therearefourchildrenintheclassroom.→Wherearethefourchildren?--They’reintheclassroom.③对数量提问:一般有两种提问方式:如果主语是可数名词,无论是单数还是复数,都用“Howmany+可数名词复数+arethere+介词短语?”表示:11)Therearetwelvemonthsinayear.→Howmanymonthsarethereinayear?12)Thereisonlyonebookinmybag.→Howmanybooksarethereinyourbag?13)Thereisacatinthebox.→Howmanycatsarethereinthebox?如果主语是不可数名词,则用“Howmuch+不可数名词+isthere+介词短语?”表示:14)Thereissomemoneyinmypurse.→Howmuchmoneyisthereinyourpurse?反意疑问句:Therebe或There加其它动词,其反意疑问句一律用…there?例如:15)Thereisabeautifulgirlinthegarden,isn’tthere?16)Thereusedtobenoschoolhere,usedthere\didthere?三、用法:1.Therebe句型中be动词的形式要和其后的主语在人称和数上保持一致。1)Thereisabasketballinthebox.2)Thereisalittlemilkintheglass.3)Therearemanybirdsinthetree.4)Thereweremanypeopleinthestreetyesterday.如果有两个或两个以上的名词作主语,be动词要和最靠近它的那个主语在数上保持一致,也就是我们常说的“就近原则”。例如:5)Thereisanorangeandsomebananasinthebasket.6)Therearesomebananasandanorangeinthebasket.2.There与be中间可插入一些表推测的情态动词、表时态的短语(如和将来时begoingto\will、现在完成时have\has+pp.)例如:1)Theremustbeapeninthebox.2)Istheregoingtobeadancingpartytonight?3)Thereisnotgoingtobeameetingtonight.4)Therehasbeenabigtreeonthetopofthehill.3.英语中有些动词或短语具有一定的情态含义,我们称之为半助动词。Therebe句型中的谓语动词be可与这些半助动词连用,表达更为复杂的意念。能用于Therebe句型中的这类词语主要有:happento(碰巧),appear/seemto(似乎),usedto(曾经),haveto(必须),belikelyto(很可能),beboundto(必定)等。例如:1)Therehappenedtobeanoldfriendofmineintheclub在那个俱乐部碰巧有我的一个老朋友。2)Thereappeartobeseveralreasonsforchangingourplans.看来改变我们的计划有几个理由。3)Thereusedtobeacinemaherebeforethewar.战前这里曾有一个电影院。4)Therehappenstobesomemoneyinmypocket.5)Thereareboundtobeobstaclesforustogetover.一定会有障碍需要我们去克服。4.Therebe+名词+地点/时间状语Therewasapartyinthehalllastnight.5.Therebe+名词+关系从句/不定式/分词1)Therearesomeclothestowash.(动宾关系)2)There’resomepeopleI’dliketorecommendtoyou.3)Thereisaroadbeingbuilt.6.由therebe构成的固定句型由therebe构成的一些固定句型在英语中很活跃,需很好地掌握。常见的有:Thereisnopoint(in)v-ing:没道理,没用,没必要Thereisnouse(in)+v-ing:毫无用处Thereisnosense(in)v-ing:毫无道理Thereisnoneed(forsb.)to+v:没有必要Thereisno+v-ing:不可能,无法。相当于“Itisimpossible+todosth.”例如:1)Thereisnouseinhidingthatfactfromhim.对他隐瞒那个事实没什么用。2)Thereisnopointinarguingfurther.再争下去也没用。3)Isthereanypointingoingon?有必要再继续下去吗?4)TherewasnoneedforhimtoremaininShanghai.他没有必要再留在上海。5)Therewasnosenseinmakingachildsufferlikethat.让一个孩子受那样的苦是毫无道理的。6)Onceletthisfellowstarttalking,therewasnostoppinghim.一旦让这个家伙谈起来,就无法让他停下来了。7.Therebe句型和have\has的区别:Therebe句型表示“存在有”,have\has表示“拥有”“所有”,两者不能同时使用.例如:1)Thetreehasmanyapplesonit.2)Therearemanyapplesonthetree.3)Therehavemanyapplesonthetree.(×)4)There’sapictureonthewall.5)Therearesixroomsinthishouse.
