英文看文法有没有错
Billy and Bobby were brothers, and they often had fights with each other.
Last Saturday their mother said to them, "I'm going to cook our lunch now. Go out and play in the garden - and be good."
"Yes, Mummy." the two boys answered, and they went out.
They played in the garden for half an hour, and then Billy ran into the kitchen, "Mummy, " he said, "Bobby's broken a window in Mrs. Allens' house."
"He's a bad boy," his mother said. "How did he break it?"
"I threw a stone at him," Billy answered,"and he quickly ducked.".
帮我看看这里的文法有没有错,让后看有没有一些字可以换成初三程度的
