初中英语语法专项复习之there be句型的常考点
No.1
there be 句型基本认识
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
注意事项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。如
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. 我们教室里有一位老师和许多学生。
③ There are to boys and a girl under the tree. 树下有两个男孩,一个女孩。

there be 句型的常考点
考点一各种句型转化
1.变成否定
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或no即可。注意not和no的不同not是副词,no为形容词,not a/an/any + n. 相当于no+ n.。例如
There are so pictures on the all. →There aren't any pictures on the all. =There are no pictures on the all.
There is a bike behind the tree. → There isn't a bike behind the tree. =There is no bike behind the tree.
2.变成一般疑问句
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。但要注意当肯定句中有so时,要将其改为any(否定变化也一样)。
There is so ater on Mars. → Is there any ater on Mars?
There are so fish in the ater. →Are there any fish in the ater?
3.特殊疑问句
对主语提问当主语是人的时候,则用ho 引导,当主语是物的时候,则用hat 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here 引导。如
There is a puter on the desk. → Where is the puter?
There are four children on the playground. →Where are the four children?
对数量提问般有两种句型结构
Ho many+复数名词+are there+介词短语?
Ho much+不可数名词+is there+介词短语?
