There be 句型用法归纳

1. 定义：There be句型表示某处存在某物或某人; 2. There be句型结构中的is/are的选择：

1 There is +单数可数名词/不可数名词+ 地点/时间状语. 2 There are +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. ① There is a bird in the tree. 树上有一只鸟;

② There is a teacher and many students in our classroom. ③ There are two boys and a girl under the tree. 3. 句式转换：

1肯定句：There is/are +名词/sb. + 地点/时间状语

2否定句：There is/are +not +名词/sb. + 地点/时间状语

There be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：

There are some pictures on the wall. →There aren't any pictures on the wall.

There is a bike behind the tree. → There isn't a bike behind the tree. 3：一般疑问句: Is / Are there+名词/sb. + 地点/时间状语

There be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： There is some water on Mars. → Is there any water on Mars There are some fish in the water. →Are there any fish in the water 4：特殊疑问句

There be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：

There are many things over there. →What's over there There is a little girl in the room.→Who is in the room

② 对地点状语提问：疑问词+ is / are+名词/sb.

例如：

There is a computer on the desk. → Where is the computer

There are four children on the playground. →Where are the four children 4. there be结构的时态

there be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： There was a sport meeting in the playground yesterday.

There will be =There is going to be a new film show on Monday. There is to be a concert at the school hall. 学校礼堂有场音乐会;

There have been a lot of accidents round here. 这里已经发生多起事故了;

He told me that there had been an argument between them. 他告诉我们之间发

生了一场争论;

There will have been a definite result by Friday. 到星期五前就已经有明确的结果

There must be a mistake somewhere. 一定在什么地方有错误;

There must have been a rain last night, for the ground is wet. 昨晚一定下了雨,因为地是湿的;

5. there be结构的变体

该结构中,有时be还可以被live, lie, stand, happen, come, go等动词代替;如： Once there lived an old fisherman in a village by the sea. 从前,在海边的一个村子里住着一个老人;

There seems little doubt that he is insane. 似乎没有多少疑问他的神经不正常; 6. there be的固定句型

There be +名词或代词+to do +介词有某事要做

There be + some/no+ trouble/difficulty in doing sth/with sth. 做某事没有困难 There be + some/no + doubt about/as to sth / that… 对某事没有疑问

There is no sense/use/good/point in doing sth 做某事没有道理/用处/好处/意义 There is no need for sb. to do sth/that… 某人做某事没有必要

There is no chance/possibility to do sth/of doing sth./that… 没有做某事的机会/可能性

There was no arguing with her. 没法和她争辩; There is a time when...有做某事的一段时间

There be＋sb.＋doing sth.＋地点/时间状语 “有某人在做某事”例如： There are several children swimming in the river.河里有几个孩子在游泳 There is something wrong with…….. be句型与have的区别：

1 用法不同：there be 表示某个时间或地方“存在”某人或某物,而have表示主语“拥有”某人或某物,作宾语的某人或某物属主语所有; 2 结构不同：

there be + sb./sth. +时间/地点副词或介词短语；sb./sth. + have +sb./sth. There are some children in the garden.花园里有几个孩子; She has three cars. 她拥有三辆汽车;汽车是属于她的

注：若是部分与整体关系时,有时用两种表达方式都可以;如：

A week has seven days. =There are seven days in a week. 一周有七天;
