1、Therebe句型的用法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:结构:(1)Thereis+单数可数名词/不可数名词+地点状语.(2)Thereare+复数名词+地点状语.1)Therearefifty-twostudentsinourclass.2)Thereisapencilinmypencil-case.3)Therewasanoldhousebytheriverfiveyearsago.二:therebe句型的常考点考点一:各种句型转化。1:变成否
2、定Therebe句型的否定式的构成和含有be动词的其它句型一样,在be后加上not或no即可。注意not和no的不同:not是副词,no为形容词,nota/an/any+n.相当于no+n.。例如:Therearesomepicturesonthewall.→Therearen'tanypicturesonthewall.=Therearenopicturesonthewall.Thereisabikebehindthetree.→Thereisn'tabikebehindthetree.=Thereisnobikebehindthetree.2:变成一般疑问句Therebe句型的一般疑问
3、句变化是把be动词调整到句首,再在句尾加上问号即可。但同时要注意:当肯定句中有some时,要将其改为any(否定变化也一样)。ThereissomewateronMars.→IsthereanywateronMars?Therearesomefishinthewater.→Arethereanyfishinthewater?3: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
4、时却要根据实际情况来决定)。如:Thereisabirdinthetree.→What’sinthetree?Therearesomebikesoverthere.→What’soverthere?Thereisalittlegirlintheroom.→Whoisintheroom?②对地点状语提问:用“Whereisare+主语?”表示(注意其答语变化):例如:Thereisacomputerinmyoffice.→Whereisthecomputer?----It’sinmyoffice.Therearefourchildrenintheclassroom.→Wherearethe
5、fourchildren?—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:Therearetwelvemonthsinayear.→Howmanymonthsarethereinayear?Thereisonlyonebookinmybag.→Howmanybooksarethereinyourbag?Thereisacatinthebox.→Howmanycatsarethereinthebox?3如果主语是不可数名词,则用“Howmuch+不可
6、数名词+isthere+介词短语?”表示: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:Thereisabeautifulgirlinthegarden,isn’tthere?Thereusedtobenoschoolhere,usedtheredidthere?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)Thereisalittlemilk
7、intheglass.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)Therearesomebananasandano
