可数名词：规则规律例子1一般情况下在名词后面直接加s.book—booksdog—dogs2以s、x、ch、sh结尾的单词加es.bus-busesbox-boxesbrush-brusheswatch-watches3以o结尾的词：有生命的加es，没有生命的加shero-heroesphoto-photos4以f、fe结尾的名词，变f、fe为v+es，wolf-wolves5以辅音字母加y结尾的名词，把y改为i，再加-es。以元音字母加y结尾的名词，直接加s。story-stories6有些名词的单复数形式相同deer-deer不可数名词：具体的量数词＋量词＋of＋不可数名词 注意：如果表示数量的词大于1，那么量词要用复数形式（例如：abottleoforange,two bottles of orange）大概的量表示量的限定词＋不可数名词 some good pieces of news可数与不可数名词的常用修饰语:一、修饰可数名词的常用修饰语有these,those,few,afew,many,agood[great]many,agreat[good]numberof等：Fewpeoplewouldagreewiththis.很少人会同意这种看法。注：agood[great]many后直接跟名词，不用介词of。但是，若其后所接名词有the,these,my等限定词修饰，则要用介词of：agreatmanyofmyfriends我的朋友当中的许多人二、修饰不可数名词的常用修饰语有this,that,little,alittle,abitof,much,agreatdealof,alargeamountof等：Ihavelittletimetodoit.我没什么时间来做此事。三、有些修饰语既可修饰可数名词也可修饰不可数名词，如all,some,enough,alotof,lotsof,plentyof,a(large)quantityof等：Youneedn’thurry.There’splentyoftime.你不必着急。时间多着哩。语法思维导图总结：名师总结：therebe句型用法及考点一：therebe句型基本认识定义：Therebe句型表示某处存在某物或某人。2、结构：Therebe+名词+地点状语.例：Thereisabirdinthetree.

树上有一只鸟。

否定结构：therebenot+名词+地点状语例：Thereisnotabirdinthetree.树上没有一只鸟。=Thereisnobirdinthetree.注：not为副词，no为形容词，nota/an/any+n.相当于no+n.一般疑问句结构：Be2：变成一般疑问句Therebe句型的一般疑问句变化是把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：特殊疑问句对主语提问：当主语是人的时候，则用who引导，当主语是物的时候，则用what引导。注意：无论原句的主语是单数还是复数，对之提问时一般都用be的单数形式(回答时却要根据实际情况来决定)。如：Therearemanythingsoverthere.→What'soverthere?Thereisalittlegirlintheroom.→Whoisintheroom?对地点状语提问：则用where引导。如：Thereisacomputeronthedesk.→Whereisthecomputer?Therearefourchildrenontheplayground.→Wherearethefourchildren?对数量提问：般有两种句型结构：Howmany+复数名词+arethere+介词短语？Howmuch+不可数名词+isthere+介词短语？考点二：therebe句型的时态。be可以有现在时（thereis/are）、过去时(therewas/were)、将来时(thereis/aregoingtobe或therewillbe)和完成时(therehave/hasbeen)；还可用theremustbe,therecan’tbe,thereusedtobe等。如：There______aconcertthisevening.Yeah.Excitingnews!A.aregoingtobe

B.isgoingtobe

C.isgoingtohave

D.willhave考点三：therebe句型反意疑问句的构成：be(not)there?如：Thereissomemilkinthebottle,____?A．isn'tthere

B．aren'tthere

C．isn'tit

D．arethere考点四：therebe句型的主谓一致：Therebe结构中的be动词要和后面所跟名词保持一致,遵循就近原则。如：1.There___anyriceinthebowl.

A.are

B.is

C.isn’t

D.aren’t2.There___manyapplesonthetreelastyear.

A.havebeen

B.were

C.are

D.is

考点五：therebe句型用的其他动词：therebe句型中有时不用动词be，而用come,live,stand,lie,seemtobe,happentobe,等。如：There____aknifeandaforkonthetable.(2007黄冈)A.seemstobe

B.

seemtobe

C.isseemingtobe

D.are剖析：根据就近原则，首先排除B、D，而therebe句型中有时不用动词be，而用come,live,stand,lie,seemtobe等，所以答案应从A、C中选。感官动词一般不用进行时，故C也不正确。注意事项：therebe句型与have句型的区别(1)Therebe句型和have都表示“有”的含义。区别如下：Therebe表示“某处存在某物或某人”；have表示“某人拥有某物/某人”，它表示所有、拥有关系。

如：Hehastwosons.

他有两个儿子。Therearetwomenintheoffice.

办公室里有两个男人。(2)当have表示“包括”、“存在”的含义时，Therebe句型与其可互换。如：Aweekhassevendays.=Therearesevendaysinaweek.

一个星期有七天。语法思维导图总结：练一练：一、单项选择
