初中英语语法专项复习之there be句型的常考点

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 two 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 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.

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）。

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?

3.特殊疑问句

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：般有两种句型结构：

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？
