There be 句型的用法
. there be 句型基本认识
1、定义:There be 句型表示某处有某物或某人。

there 是引导词,在句中不充
当任何成分,翻译时也不必译出。

这种句型之所以要用 there 作形式主语而把 “实义主语” 置于动词之后正是
为了让这种“实义主语”称为信息中心,以达到引出新话题的目的。

2、句型构成:There 十连系动词be+主语(人/物)+地点(介词短语或副词)
(1) There is +单数可数名词 / 不可数名词 + 地点状语 .
(2) There are +复数名词 +地点状语 .
:①当主语是可数名词单数或不可数名词时, be 动词用is ;
② 当主语是可数名词复数时,其 be 动词就用are ;
③ 当主语是两个或两个以上的名词时, (遵循就近原则)
be 动词要根据离它最近的名词的数来确定 be 的形式。

① There is a bird in the tree. 树上有一只鸟。

②There are two children in the room. 房间里有两个孩子。

③ There is a teacher and many stude nts in our classroom. 我 们
教室里有一位老师和许多学生。

There are two boys and a girl under the tree. 树下有两个男
孩,一个女孩。

一)如何改成否定句:直接在 be 后加上 not 或 no 即可。

例如: ① There are some pictures on the wall.
f There aren't any pi ctures on the wall. =There are no pi ctures on the wall. ② There is a bike behind the tree.
There isn't a bike behind the tree. =There is no bike behind the tree.
名词及主谓一致 对应例子: there be
句型的各种句型转化
注意:肯定句中出现some改成否定句或者疑问句时要改成any,出现and要改为or。

not禾n no 的不同:not是畐j词,no 为形容词,not
a/an/any + n.
相当于no+ n.。

(二)如何变成一般疑问句:把be动词提到句首,句末句号改
成问号即可。

同时应注意:当肯定句中有some时,要将其改为any, 而and要改成or。

例: There is some water on Mars.
T Is there any water on Mars
There are some fish in the water.
f Are there any fish in the water
在构成一般疑问句时,其句型结构为:
⑴Is + there + a^ an+单数名词+介词短语
⑵Is + there+不可数名词+介词短语
(3) Are + there + any复数名词+介词短语
⑷Are + there + any +不可数名词+介词短语
回答用Yes, there is/are.或No, there isn ' t/aren ' t.
如:—Is there a ball on the table桌子上有个球吗
—Yes,there is有
—No, there isn 没有.。

—Are there any children near the door 门边有些孩子吗
—Yes, there are.是的,有。

—No, there aren't.不是,没有。

(三)如何改成特殊疑问句:必须了解是对什么进行提问,懂得用哪个词去发问。

★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 弓I 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:
There are many thingsover there. — What's over there
There is a little girl in the room. — Whorishe room ★对地点状语提问:则用 where 引导。

女口: There is a computer on the desk.— Where is the computer
There are four childre n on the playgro und.—Where are the four childre n
★对数量提问:一般有两种句型结构,以下两种句型主要用来询问
某处有多少人或物”
如:How much milk is there in the bottle 瓶子里有多少牛奶
How many students are there in your class 你们班有多少学生
三.there be 句型的时态。

be 可以有现在时(there is/are )、过去时(there was/were)、将来时(there is/are going to be 或 there will be)和完成时(there have/has been)。

女口: ---There A. are going to be B. is going to be C. is going to have D. will have
lie, stand 等表示 存在”意义的不及物动词作为谓语动词放在 there be 句型中
如:Long, long ago, there lived a king in this area.很久很久以前有个国王住在这
儿。

a concert this eve ning. ---Yeah. Excit ing n ews!
四.There + be 这种结构中 ,谓语动词除be 之外,还可用live,
五.there be句型与have(has)句型的区别
There be句型与have(has)均表示“有”,但There be句型强调“某处有某人/某物”,着重“存在”的状态;have 则强调“某人有某物” ,着重“拥
有”。

例:(1)He has two sons. 他有两个儿子。

There are two men in the office. 办公室里有两个男人。

⑵当have表示包括”、存在”的含义时,There be句型与其可互换。

A week has seven days. =There are seven days in a week. 一个星期有七
天。

3) There are three children in my family.
我家有三个孩子。

4) I have three children. 我有三个孩子。
