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.结构：(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. 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要与主语（某人或某物）的数保持一致。当主语是两个或两个以上的名词时，谓语动词要与跟它最近的那个名词一致。（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 claroom.我们教室里有一位老师和许多学生。（就近原则）
③There are many students and a teacher in our claroom.我们教室里有许多学生和一位老师。 （就近原则） 3.There be句型与have的区别：
(1) There be 句型和have都表示“有”的含义。区别如下：There be表示“某处存在某物或某人”；have表示“某人拥有某物/某人”，它表示所有、拥有关系。
eg.①He has two sons.他有两个儿子。
②There are two men in the office.办公室里有两个男人。 4.句型转换 一：否定句
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。not a/an/any + n.(注意在改否定句的时候如肯定句中有some要改为any，一般疑问句变化也一样)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.二：一般疑问句
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。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 in the bottle.→ Is there any water in the bottle? There are some cakes on the table.→Are there any cakes on the table?
三：特殊疑问句
There be句型的特殊疑问句形式有以下三种变化：
① 对主语提问：当主语是人时，用\"Who\'s+介词短语?\"；当主语是物时，用\"What\'s + 介词短语?\"。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is(回答时却要根据实际情况来决定)。如：
There are many books 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：提问地点用”Where is / are+主语”。
例如：
There is a computer on the desk.→ Where is the computer? There are four children in the claroom.→Where are the four children? ③ 对数量提问：
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： There are twelve months in a year.→How many months are there in a year? There is some money in my purse.How much money is there in your purse?
