简单填空
I am looking out of my window.I can see some children in the street.The children_________(play)football.They always_________(play)football in the street.
Now a little boy_____________(kick)the ball.Another boy_______________(run) after him but he cannot catch him.
是否是 play,play,kicking,running.
是否可以怎么判断?看时间的词,判断句子时态?
有那些频率的副词,什么always,often等等,基本都是一般现在时?
