1、5初中therebe句型用法及配套練習(xí)一:therebe句型基本認(rèn)識1、定義:Therebe句型表示某處存在某物或某人。2、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.(2)Thereare+復(fù)數(shù)名詞+地點(diǎn)狀語.注意事項(xiàng):?there是引導(dǎo)詞,在句中不充當(dāng)任何成分,翻譯時(shí)也不必譯出。句子的主語是某人或某物,謂語動(dòng)詞be要與主語(某人或某物)的數(shù)保持一致。當(dāng)主語是兩個(gè)或兩個(gè)以上的名詞時(shí),謂語動(dòng)詞要與跟它最近的那個(gè)名詞一致。如:①Thereisabirdinthetree.??樹上有一只鳥。???②Thereisateacher
2、andmanystudentsinourclassroom.?我們教室里有一位老師和許多學(xué)生。???③Therearetwoboysandagirlunderthetree.樹下有兩個(gè)男孩,一個(gè)女孩。二:therebe句型的??键c(diǎn)考點(diǎn)一:各種句型轉(zhuǎn)化。1:變成否定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'tany
3、picturesonthewall.=Therearenopicturesonthewall.Thereisabikebehindthetree.→Thereisn'tabikebehindthetree.=Thereisnobikebehindthetree.2:變成一般疑問句Therebe句型的一般疑問句變化是把be動(dòng)詞調(diào)整到句首,再在句尾加上問號即可。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?Therearesome
4、fishinthewater.→Arethereanyfishinthewater?3:特殊疑問句對主語提問:當(dāng)主語是人的時(shí)候,則用who引導(dǎo),當(dāng)主語是物的時(shí)候,則用what引導(dǎo)。注意:無論原句的主語是單數(shù)還是復(fù)數(shù),對之提問時(shí)一般都用be的單數(shù)形式(回答時(shí)卻要根據(jù)實(shí)際情況來決定)。如:Therearemanythingsoverthere.→What'soverthere?Thereisalittlegirlintheroom.→Whoisintheroom?對地點(diǎn)狀語提問:則用where引導(dǎo)。如:Thereisacomputeronthede
5、sk.→Whereisthecomputer?Therearefourchildrenontheplayground.→Wherearethefourchildren?對數(shù)量提問:般有兩種句型結(jié)構(gòu):Howmany+復(fù)數(shù)名詞+arethere+介詞短語?Howmuch+不可數(shù)名詞+isthere+介詞短語?考點(diǎn)二:therebe句型的時(shí)態(tài)。be可以有現(xiàn)在時(shí)(thereis/are)、過去時(shí)(therewas/were)、將來時(shí)(thereis/aregoingtobe或therewillbe)和完成時(shí)(therehave/hasbeen);還可用
6、theremustbe,therecan’tbe,thereusedtobe等。如:---There______aconcertthisevening.5??????????---Yeah.Excitingnews!???????A.aregoingtobe???B.isgoingtobe???C.isgoingtohave???D.willhave考點(diǎn)三:therebe句型反意疑問句的構(gòu)成:be(not)there?如:Thereissomemilkinthebottle,____???????????????????A.isn'tthere
7、????B.a(chǎn)ren'tthere???C.isn'tit???D.a(chǎn)rethere考點(diǎn)四:therebe句型的主謂一致:Therebe結(jié)構(gòu)中的be動(dòng)詞要和后面所跟名詞保持一致,遵循就近原則。如:1.There___anyriceinthebowl.??????????????????????????A.are?????B.is?????C.isn’t????D.aren’t2.There___manyapplesonthetreelastyear.?????A.havebeen???B.were?????C.are?????D.is??考點(diǎn)五
8、:therebe句型用的其他動(dòng)詞:therebe句型中有時(shí)不用動(dòng)詞be,而用come,live,stand,lie,seemtobe,happento
