Billy and Bobby were small boys．They were brothers，and they often had2 fights3 with each other．
Last Saturday their mother said4 to them，I'm going5 to cook our lunch now．Go out and play in the gardenand be good．
Yes，Mummy， the two boys answered，and they went out．
They played in the garden for half an hour，and then Billy ran6 into the kitchen．Mummy， he said，Bobby's broken7 a window in Mrs．Allen's house． Mrs．Allen was8 one of their neighbors9．
He's a bad boy，his mother said．How did10 he break it？
I threw a stone at him， Billy answered，and he quickly moved down．
10．是他的错
比利和波比都是小孩子。他们是兄弟，两人常常打架。
上个星期六，他们的母亲对他们说：我目前要做午饭了。去，到花园去玩吧，别淘气。
是，母亲，两个男生回答，然后他们就出去了。
他们在花园里玩了半个小时，然后比利跑进了厨房。母亲，他说：波比打碎了艾伦太太家的窗玻璃。艾伦太太是他们的邻居。
他是个坏孩子，他的母亲说。他是如何把玻璃打碎的？
我朝他扔了一块石子，比利回答：他快点蹲下。
