there is 後面的動詞形式
There be後面有兩種動詞形式:
1、There be sb. / sth. doing 
在這個句型中,doing表示的動作是sb. /sth.本身的動作
例句:
There are many kites flying in the sky.天空上有許多風箏在飛。
There are many people working there.有許多人在那裏工作。
2、There be sb. / sth. to do 
在這個句型中,to do表示的動作不是是sb. /sth.本身的動作
例句:
There are still many people for you to visit。
There are many places of interest to visit in China。
there is 就近原則,例如There is a book. There are two books. 後面的單詞加doing,例如 There is a baby crying outside.
