1、Therebe句型的用法Therebe句型的用法一、構(gòu)成:Therebe...句型表示的是“某處有(存在)某人或某物”,其結(jié)構(gòu)為T(mén)herebe(is,are,was,were)+名詞+地點(diǎn)狀語(yǔ)。例如:結(jié)構(gòu):(1)Thereis+單數(shù)可數(shù)名詞/不可數(shù)名詞+地點(diǎn)狀語(yǔ).(2)Thereare+復(fù)數(shù)名詞+地點(diǎn)狀語(yǔ).1)Therearefifty-twostudentsinourclass.2)Thereisapencilinmypencil-case.3)Therewasanoldhousebytheriverfiveyearsago.二:therebe句型的常考點(diǎn)考點(diǎn)一:各種句型轉(zhuǎn)化。1:變成否
2、定Therebe句型的否定式的構(gòu)成和含有be動(dòng)詞的其它句型一樣,在be后加上not或no即可。注意not和no的不同:not是副詞,no為形容詞,nota/an/any+n.相當(dāng)于no+n.。例如:Therearesomepicturesonthewall.→Therearen'tanypicturesonthewall.=Therearenopicturesonthewall.Thereisabikebehindthetree.→Thereisn'tabikebehindthetree.=Thereisnobikebehindthetree.2:變成一般疑問(wèn)句Therebe句型的一般疑問(wèn)
3、句變化是把be動(dòng)詞調(diào)整到句首,再在句尾加上問(wèn)號(hào)即可。但同時(shí)要注意:當(dāng)肯定句中有some時(shí),要將其改為any(否定變化也一樣)。ThereissomewateronMars.→IsthereanywateronMars?Therearesomefishinthewater.→Arethereanyfishinthewater?3:特殊疑問(wèn)句:Therebe句型的特殊疑問(wèn)句有以下三種形式①對(duì)主語(yǔ)提問(wèn):當(dāng)主語(yǔ)是人時(shí),用“Who’s+介詞短語(yǔ)?”;當(dāng)主語(yǔ)是物時(shí),用“What’s+介詞短語(yǔ)?”。其中there在口語(yǔ)中常常省略。注意:無(wú)論原句的主語(yǔ)是單數(shù)還是復(fù)數(shù),對(duì)其提問(wèn)時(shí)一般都用be的單數(shù)形式(回答
4、時(shí)卻要根據(jù)實(shí)際情況來(lái)決定)。如:Thereisabirdinthetree.→What’sinthetree?Therearesomebikesoverthere.→What’soverthere?Thereisalittlegirlintheroom.→Whoisintheroom?②對(duì)地點(diǎn)狀語(yǔ)提問(wèn):用“Whereisare+主語(yǔ)?”表示(注意其答語(yǔ)變化):例如:Thereisacomputerinmyoffice.→Whereisthecomputer?----It’sinmyoffice.Therearefourchildrenintheclassroom.→Wherearethe
5、fourchildren?—They’reintheclassroom.③對(duì)數(shù)量提問(wèn):一般有兩種提問(wèn)方式:如果主語(yǔ)是可數(shù)名詞,無(wú)論是單數(shù)還是復(fù)數(shù),都用“Howmany+可數(shù)名詞復(fù)數(shù)+arethere+介詞短語(yǔ)?”表示:Therearetwelvemonthsinayear.→Howmanymonthsarethereinayear?Thereisonlyonebookinmybag.→Howmanybooksarethereinyourbag?Thereisacatinthebox.→Howmanycatsarethereinthebox?3如果主語(yǔ)是不可數(shù)名詞,則用“Howmuch+不可
6、數(shù)名詞+isthere+介詞短語(yǔ)?”表示:Thereissomemoneyinmypurse.Howmuchmoneyisthereinyourpurse?反意疑問(wèn)句:Therebe或There加其它動(dòng)詞,其反意疑問(wèn)句一律用…there?例如:Thereisabeautifulgirlinthegarden,isn’tthere?Thereusedtobenoschoolhere,usedtheredidthere?1.Therebe句型中be動(dòng)詞的形式要和其后的主語(yǔ)在人稱(chēng)和數(shù)上保持一致。1)Thereisabasketballinthebox. 2)Thereisalittlemilk
7、intheglass.3)Therearemanybirdsinthetree. 4)Thereweremanypeopleinthestreetyesterday. 如果有兩個(gè)或兩個(gè)以上的名詞作主語(yǔ),be動(dòng)詞要和最靠近它的那個(gè)主語(yǔ)在數(shù)上保持一致,也就是我們常說(shuō)的“就近原則”。例如:5)Thereisanorangeandsomebananasinthebasket.6)Therearesomebananasandano
