Question

There are five boys ________basketball on the playground？

Answer 1

There are five boys playing basketball on the playground.有五个男孩正在操场上打篮球.,1,playing,2,playing,2,playing,0,事实上最完整的说法应该埋拍晌是：There are five boys （who are）playing basketball on the playground

there be句型其实是定语从句的省略句形式罢了。

不过楼主需要学习了定语从句，才会明白我弯锋贺烂说的话。,0,playing,0,playing,0,
