There be 句型课程讲解（一） 一、There be 句型的用法： 表示某个地方存在某物或某人，可以翻译成有的意思。Be动词的单复数必须依主语的变化而变化。如：房间里有一张桌子。There is a table in the room. 区别: 表达一个人拥有某样东西时则用have/has,如:我有一张桌子。I have a table. There be 结构和have的区别与联系 1.区别点：there be 意为存在，强调某地有某物，不表示所属关系；have 表示所有关系， 强调某地有某物或某人，这是其基本用法。如： There are some trees in front of the house. 房前有些树。 Tom has many friends in China. 汤姆在中国有许多朋友。 2.相同点：在表示结构上的含有时，既可以用there be 句型，也可以用have（has）来表示。如：中国有许多长河。 There are many long rivers in China. China has many long rivers.三月份有多少天How many days are there in MarchHow many days has March 二、There be 句型的结构： There is+第三人称单数可数/不可数主语+地点状语（介词短语） 例：There is a ruler on the desk. 书桌上有一把尺。 There is some water in the bottle. 瓶子里有一些水。 There are+复数主语+地点状语（介词短语） 例：There are four apples on the tree. 树上有四个苹果。 There are many flowers in the park. 公园里有许多花。 There is+第三人称单数可数+V-ing+地点状语（介词短语） 例：There is a bird singing in the tree. 树上有一只鸟正在唱歌。 There is a baby sleeping in the room. 房间里有一个宝宝正在睡觉。 There are+复数主语+V-ing+地点状语（介词短语） 例：There are some birds singing in the tree. 树上有一些鸟正在唱歌。 There are two boys running on the street. 街上有两个男孩正在奔跑。
“there be”句型的几种特殊用法
There be 句型的几种特殊结构及其用法 There be句型是一种应用十分广泛和频繁的句型。但是对there be句型的多变的特点及其特殊结构的复杂性，并不是每个考生都熟悉了解。在大学英语四级考试题中也常常遇到这一句型结构的试题。 例如： Ann never dreams of _________ for her to be sent abroad very soon．（CET-4，1998．6-43） A）there to be a chance B）there being a chance C）there be a chance D）being a chance 该题的答案为B）。 动词 dream of 要求跟 V-ing 分词结构作宾语，更准确地讲是介词of后要求跟 V-ing 分词结构作宾语，there being a chance意为"有一个机会"；A）和C）两项均不符合句子结构的要求，所以不是答案选项，而D）项 being a chance 虽然是 V-ing 分词结构，但语义不通，故不能雪 又如： No one had told Smith about ____ a lecture the following day．（CET-4，2001．1-66） A）there be B）there would be C）there was D）there being 该题的答案为D）。介词 about 后要求跟 V-ing 分词结构作宾语，there being（a lecture）意为"有（一个讲座）"，而A）、B）和C）项内容均不符合结构要求，故不能雪 再如： It is fairly common in Africa for there to be an ensemble of expert musicians surrounded by others who join in by clapping，singing，or somehow adding to the totality of musical sound．（CET-4，1995．1） 该句子中出现了for there to be 的结构，如果按照上一题的解题思路去理解：介词后要求跟 V-ing 分词结构作宾语，那么，这一结构似乎是错的；但是，实际上此结构没有错，此处只能够用 for there to be，而不能用 there being。为什么呢？这就是本文想要解答的问题：there be 句型的特殊结构及其用法。笔者将 there be 句型的几种特殊结构及其用法进行归纳、总结如下，供读者参考。 一、there be句型与各种情态动词连用。 例如： There must be something wrong here． There might still be some vacant seats in the rear． There ought to be something with which to fill your stocking． 二、there be句型中的谓语动词be被be likely to be，happen to be，seem（to be）， occur等代替，用来描写事物。例如： ] There are likely to be more difficulties than they have been prepared for． There happened to be nobody in the room． There doesn’t seem to be much hope of our beating that team ． There seems no doubt that the general character of the landscape，the relative length of day and night，and the climate must all play a big part in determining what kind of people we are． There have occurred many great changes since we met last． 三、there be 句型中的谓语动词be被一些不及物动词代替，如 live，stand，exist，remain等，用来表示"静止、存在、有"。例如： There lives a family of five in the village． There remains nothing more to be done． There stands the Monument to the People’s Heroes at the center of the Tian’anmen Square． There exist different opinions on this question． 四、there be 句型中的谓语动词be被一些不及物动词代替，如 come，spring up，appear，emerge，arrive，enter，follow, 等，用来表示"突然出现"。例如：

There be结构中的动词be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is,是复数时用are。如: There is a flower in the bottle. 瓶里有一朵花。 There is 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 is 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。 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。 二、 There be 结构的句型转换 1. 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,is not=is n’t are not=are n’t)。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. 2.一般疑问句及其回答:把be提到there前,首字母大写,句末用问号即可(句中的some一样要改为any)。其肯定回答是Yes, there is / are;否定回答为No, there isn't / aren't。如: -Are there two cats in the tree? -Yes, there are. (No, there aren't.) 3. 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 is + 地点介词短语?"(无论主语是单数还是复数都用is)。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 is / are + 主语?"如: There is a car in the street. →Where is 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)。如: The re is a cat under the bed. →How many cats are there under the bed? 三、There be句型与have、has的区别： (1) There be 句型和have, has都表示“有”的含
It的用法及典型句型归纳. 个人总结
It的用法及典型句型归纳 一、人称代词it的最基本用法是作代词，主要指刚提到的事物，想法，以避免重复;也可以指性别不明或性别被认为是不重要的人或动物；未指明但谈话双方都明白的事情或情况。 ①They watched the train until it disappeared in the distance. ②Is this your dog？No, it isn’t. ③I hate it when people talk with a full mouth.． 二、.非人称代词.it有时并不指具体的东西而泛指天气、时间、日期、距离、价值、度量、温度、环境等： It is a lovely day, isn’t it? // It was nearly midnight when she came back. It is April First today. // It is some 3000 kilometers from A to B. It is three dollars. // Today it is 30 degrees centigrade. 三、作形式主语，替代主语从句，动词不定式，或动名词短语 1.作形式主语替代主语从句 ⑴It is clear ( obvious，true，possible，certain....) that ＂┅清楚的（显然的，真的，可能的,肯定的．．．）＂ ⑵It is important ( necessary，right，strange，natural...) that + (should ) do (虚拟语气) ┅是重要的(必要的,对的,奇怪的,自然的┅) ⑶It is said (reported/ learned/believed/thought/known/told/hoped.....) that = sb / sth is said (reported/ believed /thought…) to do( to be doing/ to have done) sth ＂据说（据报道，据悉．．．）＂。 ⑷It is suggested ( advised/ ordered / demanded/ insisted/ commanded... ) that +(should ) do ＂据建议；有命令．． ⑸It is a pity ( a shame /an honour/a good thing/a fact,/a surprise/... ) that that后的从句一般用虚拟语气（should + 动词原形），should可省去．表示出乎意料，常译为＂竟然＂。没有这种意义时，则不用虚拟语气。 小练一下： It is very clear that he’s round and tall like a tree. = It is important that we (learn) English well. It is necessary that he (remember) these words. It is said that he has come to Beijing. = It is reported that another earth satellite has been put into orbit. = It is suggested that the meeting ( put off). It was ordered that we (arrive) there in two hours. It is a pity that such a thing ( happen) in your class. It is a pity that he (be) ill. 2.作形式主语替代不定式 . ⑴It is kind ( of sb. ) to do sth.= sb be kind to do sth.一般都是表示人的特性的形容词。如： bad /brave /careless/ clever /cruel / foolish / good （好心的）/ honest/ kind / lazy / modest/ naughty/ nice（有教养的）/polite/ rude / silly / stupid / wise ，等。 Eg. It is kind of you to give me a hand. = ⑵It is necessary ( for sb. ) to do sth. .不定式的逻辑主语是由for引起。常见的形容词有： Important/ necessary/ natural/ easy / safe / common / normal / hard / difficult / dangerous/ unusual/ rare / impossible / pleasant Eg. It is important for her to come to the party.

Therebe句型用法归纳
T h e r e b e句型用法归纳 1.定义：Therebe句型表示某处存在某物或某人。 2.Therebe句型结构中的is/are的选择： (1)Thereis+单数可数名词/不可数名词+地点/时间状语. (2)Thereare+复数名词+地点/时间状语. there是引导词，在句中不充当任何成分，翻译时也不必译出。句子的主语是某人或某物，谓语动词be要与某人或某物的数保持一致。当be后是两个或两个以上的名词时，谓语动词要与跟它最近的第一个名词一致即采用就近原则。 eg.①Thereisabirdinthetree.树上有一只鸟。 ②Thereisateacherandmanystudentsinourclassroom. ③Therearetwoboysandagirlunderthetree. 3.句式转换： (1)肯定句：Thereis/are+名词/sb.+地点/时间状语 (2)否定句：Thereis/are+not+名词/sb.+地点/时间状语 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即可。例如：Therearesomepicturesonthewall.→Therearen'tanypicturesonthewall.Thereisabikebehindthetree.→Thereisn'tabikebehindthetree. (3)：一般疑问句:Is/Arethere+名词/sb.+地点/时间状语? 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，此为"调整法"。 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）。看看下面两句是如何"改头换面"的吧： ThereissomewateronMars.→IsthereanywateronMars? Therearesomefishinthewater.→Arethereanyfishinthewater? (4)：特殊疑问句 Therebe句型的特殊疑问句形式有以下两种变化： ①对名词/sb.提问：用"Who/What+is+介词短语?" 注意：无论原句的名词是单数还是复数，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? ②对地点状语提问：疑问词+is/are+名词/sb.? 例如： Thereisacomputeronthedesk.→Whereisthecomputer? Therearefourchildrenontheplayground.→Wherearethefourchildren? 4.therebe结构的时态 therebe结构有不同的时态，而且可以和各种助动词或情态动词连用。如：Therewasasportmeetingintheplaygroundyesterday. Therewillbe(=Thereisgoingtobe)anewfilmshowonMonday. Thereistobeaconcertattheschoolhall.学校礼堂有场音乐会。Therehavebeenalotofaccidentsroundhere.这里已经发生多起事故了。Hetoldmethattherehadbeenanargumentbetweenthem.他告诉我们之间发生了一场争论。TherewillhavebeenadefiniteresultbyFriday.到星期五前就已经有明确的结果Theremustbeamistakesomewhere.一定在什么地方有错误。Theremusthavebeenarainlastnight,forthegroundiswet.昨晚一定下了雨，因为地是湿的。 5.therebe结构的变体
