There is a picture on the wall. There is a bag behind the chair. There are many books on the desk. There are many people in the hall. There be句型中的be动词要和后面的主语在数上保持一致 （1）如果句子的主语是单数可数名词或不可数名词时，be动词就用is.如： There is a table in the room. 房间里有一张桌子。 There is a little water in the bottle. 瓶子里有一点水。 （2）如果句子的主语是复数名词时，be动词就用are。如： There are some pencils on the chair. 椅子上有一些铅笔 就近原则 （3）如果有两个或两个以上的主语时，be动词要和最靠近它的那个主语在数上保持一致。如： There is a pen and some books on the desk. 书桌上有一支钢笔和一些书。 There are some books and a pen on the desk. 书桌上有一些书和一支钢笔。 There is/are--- 的否定句is/are后加not, 肯定句中的some变any There is a beautiful flower on the desk. There is not a beautiful flower on the table. There is some water in the bottle. There isn’t any water in the bottle. There is/are--- 的一般疑问句 is/are要提前, some 变any,其他都不变 There is a radio on the desk.(一般疑问句) Is there a radio on the desk ? Yes, there is. / No, there isn’t There are some shoes under the bed.（一般疑问句） Are there any shoes under the bed? Yes, there are. / No, there aren’t. 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后面的地点状语进行提问，用“Where is / are+主语”表示，注意其答语变化。如： （1）There is a car under the tree. →Where is the car? It’s under the tree. （2）There are three apples on the table. → Where are the three apples? They’re on the table. c)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? 总结 特殊疑问句--- 对人提问用who’s, 对事物提问用what’s， be动
