Are there any shoes under the bed

There is/are--- 的特殊疑问句
a）就There be后面的主语进行提问，
指物用“What’s ( there ) … ”
指人用“Who’s ( there ) … ”
其中的there在口语中经常省略。值得注意的是，无论是原句的主语是单数还是复数，提问时动词be均用单数。如：
（1）There are some bikes in the room
→ What’s (there) in the room
（2）There is a boy in the house.
→ Who’s (there) in the house
b)对There be后面主语的数量进行提问
如果主语是可数名词，无论是单数还是复数，均用“How many+复数名词+are there+地点介词短语”表示；
There are three bikes in the house.
How many bikes are there in the house
There is a boy in the room.
如果主语是不可数名词，则用“How much + 不可名词+is there+地点介词短语”表示。如：
There is a little water in the bottle.
→ How much water is there in the bottle
There be句型有特点，主语跟在be后边。
单数主语用is，复数用are记心间，
多个主语并列时，be随身边主语变。
变否定，很简单，be后要把not添。
变问句也不难，把be提到there前。
肯定句中用 some，否定疑问any 换。
