问题描述:

on Saturday afternoon they began with the back of the house
The next Saturday Tom went to a football match while his wife painted the front of the house?The next day they found they couldn't open any of the front windows?They get them open at last,but they broke three of the seven and they were very expensive to repair

第一句是不是the last Saturday?因为后面都是过去式,赫赫
上星期六当汤姆的妻子粉刷房子前面的时候汤姆去看一场足球比赛了,第二天他们发现所有前面的窗子都打不开了.虽然他们最后终于把它们打开了,但七个窗户里破掉了三个,而且修理费用非常高.
