     "Are all those children yours? "he asked the woman.

     "Yes, they are," she answered.

     "Do you always dress them in the same clothes?"asked Mr. Robinson.

we dress them like this because we do not want to take other children home by mistake(错误). When

there are other children among ours, it is easy to see them because their clothes are different."
