eg. ① There is a bird in the tree.
② There is a teacher and many students in our classroom.
③ There are two boys and a girl under the tree.
2、There be句型与have的区别:
There be 句型和have都表示有的含义。区别如下:There be表示某处存在某物或某人have表示某人拥有某物/某人,它表示所有、拥有关系。 eg.①He has two sons.
②There are two men in the office.
当have表示包括、存在的含义时,There be 句型与其可互换。
eg. A week has seven days. =There are seven days in a week.
3、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 arent any pictures on the wall. =There are no pictures on the wall.
There is a bike behind the tree. There isnt a bike behind the tree. =There is no bike behind the tree.
4、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Whos+介词短语?当主语是物时,用Whats + 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:
