There be句型的用法 一．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
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.名词及主谓一致：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。
对应例子：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。
③There are two boys and a girl under the tree.树下有两个男孩，一个女孩。二． there be 句型的各种句型转化
（一）如何改成否定句：直接在be后加上not或no即可。例如： There are some pictures on the wall.→There aren't any pictures on the wall.=There are no pictures on the wall.There is a bike behind the tree.→ There isn't a bike behind the tree.=There is no bike behind the tree.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。
（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.→ Is there any water on Mars? There are some fish in the water.→Are there any fish in the water? 在构成一般疑问句时, 其句型结构为:(1)Is + there + a／an+单数名词+介词短语?
(2)Is + there+不可数名词+介词短语?
(3)Are + there + any +复数名词+介词短语? 1
(4)Are + 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’t.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 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：
There are many things over there.→What's over there? There is a little girl in the room.→Who is in the room? 对地点状语提问：则用where 引导。
如：There is a computer on the desk.→ Where is the computer? There are four children on the playground.→Where are the four children?
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”
How many+复数名词+are there+介词短语？
How much+不可数名词+is there+介词短语？
如：How much milk is there in the bottle? 瓶子里有多少牛奶?
How many students are there in your cla? 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)。
如：---There ______ a concert this evening.---Yeah.Exciting news!
A.are going to be B.is going to be
C.is going to have
D.will have 四．There + be这种结构中, 谓语动词除be之外，还可用live, 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 2 儿。
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。
(2)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。
