It's two . The children _____football____in the football field.A.play , happy B . is playing , happily C. are playing , happily D. playing, happy

Answer 1

C
It's two.现在两点。具体的时间点要用进行时。children是孩子们，复数名词，后面的be动词只能用are，所以选C

Answer 2

B the特指用is , 看 It's two 可以知道应该用进行时，副词修饰动词“玩”得开心

Answer 3

C
分析：某个时间正在做某事，主语是复数，排除A与B　，修饰动词用副词，再排除D
