there be 的否定句及疑问句要注意的问题

Answer 1

There be 句型“变脸”记
川剧中的\"变脸\"变化多端橡粗,精彩绝伦,令人叹为观止!There be句型是我们刚认识不久的好朋友,看看它是怎样\"变脸\"的吧.
1.变脸一：销如戚否定句
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.变脸二：一般疑问句
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,此为\"调整法\".但同时要注意：当肯定句亏陵中有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 on Mars.→ Is there any water on Mars?
There are some fish in the water.→Are there any fish in the water?
3.变脸三：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(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?
② 对地点状语提问：提问地点当然用\"Where is / are+主语?\"啦!例如：
There is a computer on the desk.→ Where is the computer?
There are four children on the playground.→Where are the four children?
③ 对数量提问：一般有两种句型结构：
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?
