改错：Yesterday my aunt went shopping and asked me take care of my two little lovely cousins.I was busy for my homework,but I let them read picture books by themselves.Moment later,I found the pages of a book tearing and lying all over the floor .When I asked them whom did that,the elder sister slowly nodded and bent down her head.Saw that she was true sorry,I just smiled,gave her some biscuits and told her not to do that again.When his younger brother saw the biscuit ,he asked why he wasn't given any .she answered ,"You don' t tear not the pages of the book ,but I did ."
