(二):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?
考点二: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);还可用there must be ,there can’t be, there used to be等。 如:
---There ______ a concert this evening.
考点三:there be 句型反意疑问句的构成:be (not) there? 如:
There is some milk in the bottle, ____ ?
A.isn't there B.aren't there C.isn't it D.are there
考点四:there be 句型的主谓一致:
There be 结构中的be动词要和后面所跟名词保持一致,遵循就近原则。如:
1.There ___ any rice in the bowl.
A. are B. is C. isn’t D. aren’t
