结构
there be+sth+地点状语
there ** a flower in the bottle.瓶里有一朵花。there ** some money in the purse.钱包里有些钱。there be+no+n.+in doing sth
1.其中名词为表“利弊”、“用途”的抽象名词，如：there ** no good in going.去没有什么好处。there ** no harm in doing that.那样做并无害处。2.其中名词为表“价值”、“意义”的抽象名词，如：there ** no sense in waiting here.在这里等候下去毫无意义。there ** no d**grace in failing once.一旦失败也不丢脸。（注：此结构中的介词可以省略，如：there ** no use asking her—she doesn’t know anything.）
there **+no+doing something
1.其中的动词（do）多为“转述”或“认知”等意义的动词，如：tell,say,know等，其后一般跟疑问句，如when，what等。there ** no saying what may happen.很难说会发生什么事。there ** no telling when he will return.说不清他何时回来。there ** no knowing when we shall meet again.不知何时我们能再相会。2.其他动词，其意义相当灵活。there ** no m**taking what ought to be done.应该做什么是清楚的。there ** no denying the fact.事实无可否认。there ** no holding back the wheel of h**tory.历史的车轮不能倒转。there ** no getting along with him.他很难相处。once she starts talking,there ** no stopping her.一旦她打开话匣子，就说个没完。there ** no joking with him.和他不能开玩笑。there **+no+action noun
1.此结构的含义相当于it’s impossible/unnecessary to do something。there ** no hurry about it.没有必要这么急匆匆的。there ** noquestion of h** honesty.他的诚实是勿庸置疑的。2.有时，在此结构中的action noun被动名词形式所取代，其意义不变。there ** no escape from the evident.there ** no escaping the fact.两句都表示：无法逃（躲）避…但是，有时也存在意义上的区别，a.there ** no doubt at all about it.b.there ** no doubting her virtue.句a为“存在句”，意即：对于此事不存在任何的疑问。句b则是不表“存在”的一种惯用结构，意即：她的贞操勿庸置疑。3.以上三种结构除用于陈述句外，尚可见于疑问句。如：** there any use in d**cussing the matter further?这种事再讨论下去有何益处？** there any hurry about it?这事需要匆忙吗？此惯用结构中的be有时可与情态动词连用，其语气更趋委婉。如：there could be no m**taking where he had come from.他从哪里来是相当清楚的。此结构中的no也不是一成不变的，它可被其他形式所取代。如：there **n’t any getting away from it.要从它那里逃脱是不可能的。there was never believing half of what he said.他的话连一半也不信。there’s never any predicting what they will do next.无法料及他们下一步将会干什么
there be结构中的be动词的确定
1.there be 结构中的谓语动词be在人称和数上应与其后的主语保持一致。主语是不可数名词或单数可数名词时用**,是复数时用are。如:there ** a flower in the bottle.瓶里有一朵花。there ** some money in the purse.钱包里有些钱。2.若句子中有几个并列的主语时,be的形式要与离其最近的一个主语在人称和数上保持一致。如:there ** a boy,a girl and two women in the house.房子里有一个男孩,一个女孩和两个妇女。there are ten students and a teacher in the office.办公室里有十个学生和一个教师。3.另外,在陈述句中为了强调地点,也可将介词短语提置句首。如:in the tree there are five birds.树上有五只鸟。there be 结构的句型转换
否定句
there be的否定式通常在be后加not构成(在口语中be时常与not缩写在一起)。如果句中有some,一般要变成any。如:there are some children in the picture.→there aren't any children in the picture.
一般疑问句及其答语
把be提到there前,首字母大写,句末用问号即可。其肯定答语是yes,there **/are;否定答语为no,there **n't/aren't。如:—are there two cats in the tree?yes,there are.(no,there aren't.)
特殊疑问句及其回答
①提问句子的主语(包括主语前的修饰语)时,句型一律用"what **+地点介词短语?(无论主语是单数还是复数都用**)。如:there are some birds in the tree.→what's in the tree?②就there be后面的地点状语进行提问时,句型用"where **/are+主语?如:there ** a car in the street.→where ** the car?③提问可数名词(主语)前的数量时,用how many,句型结构为"how many+复数名词+are there+其它?(主语无论是单数还是复数,be通常要用are)。注意
当there be后面的名词时单数或不可数名词时be用**，当后面是可数名词复数时，be用are。“there be.”句型是存在句的常用基本结构，there在句中处于主语位置，起形式主语的作用，真正的主语是随后的名词词组。其谓语动词通常是be的各种时、体等形式。如：there ** ice on the lake.湖上有冰。there were three students in the classroom then.当时教室有三个学生。there has never been anybody like you.从来还没有像你这样的人。there will be snow on high ground.在高地上将会有雪。除此之外,there be句型还有一些特殊的结构：1.there+情态助动词+be表示“预见”、“可能”、“必然”或“过去习惯存在”等。如：there might be some desserts if you wait a bit.如果你等一会儿，可能会有甜点。there ought to h**e been someone on duty all the time.本来应该有人全天值班。there shall be no wars.再也不会打仗了。也可以用there+某些半助动词+be(很少使用完成体形式)，如：be going to,be certain to,be sure to,be likely to,h**e to be等。there ** going to be a rain.要下雨了。there's likely to be an interview.可能会有一场面试。there has to be a m**take.必定有错。2.在正式文体中，某些表示存在、发生、出现、坐落等意义的不及物动词也可以与there连用，如：appear,seem,come,remain,ex**t,live,stand,lie,ar**e,enter,follow,occur,r**e,grow,happen,belong,arrive,fly,flash,sail,pass,run,spring up,emerge等。如：there ex**t many ancient temples in the country.那个**有很多古老的寺庙。there lies a small village in the mountain.山里有个小村子。once upon a time,there lived an old queer man in the city.从前，城里住着个怪老头。there remains nothing to be done.没有什么别的事可做了。there followed the first world war.接着就是第一次世界大战。there flashed through h** mind the image of a heroic fighter.他的头脑中闪过英雄战士的形象。there sprang up a wild gale.突然刮起一阵狂风。偶尔也能见到there后接及物动词：there struck me a sudden idea.突然我有了一个主意。如果句中的地点状语前移就可以省略there。如：behind the house(there)** a small river.3.there+不定式to be 或there+being形式，称为非限定存在句，可以作主语、宾语、介词补足成分。1)作主语 there being a railway station in the town ** a great advantage.镇上有个火车站，真方便呀！“there to be+np”作主语时，通常用for作引导词:for there to be a m**take in a computer's arithmetic ** impossible.计算机计算错误是不可能的。it was seldom for there to be no late comers.新来者很少没有迟到的。2)作宾语 the committee anticipated there being less debate in the second d**cussion.委员会期望在第二次讨论中争议能少一些。we expect there to be no objections.我们希望不会有人反对。i'd prefer there to be cooperation.我希望有更多的合作。3)作介词补足成分 介词是for,用there to be形式；介词不是for，则用there being形式。what's the chance of there being an election th** year?今年进行选举的可能性有多大？we h**e no objection to there being a meeting here.在这儿举行会议，我们不反对。jill ** waiting for there to be a big party.吉尔等着举行一次盛大的晚会。此外，there+being形式还可以用作状语分句，形成独立主格结构：there being no further d**cussion,the chairman stood up and left the meeting-room.没有可讨论的了，**站了起来，离开了会议室。there h**ing been no rain，the stream was dry.一直没有下雨，小溪都干涸了。句式分辨
“there be.”句型的难点在于它的非限定形式,怎样分辨使用there to be 和there being 呢?两个要点是关键：它们在句子中的成分及与句子中其他成分的搭配关系。如非限定形式的第2小点中的例句：anticipate与there being搭配，而expect 和prefer与there to be配伍。
