“Are all the children yours?” he asks the woman.
“Yes, they are.” she answers.
Mr Brown smiles and touches a boy's head. He says, “They are lovely.”
The woman smiles, too. She says: “Thank you.”

“Yes,” answers the mother, “When we have four children, we dress them in the same clothes, because we don't want to lose(丢失) any of them. It's easy to see our children among (在….当中) other children because they are all wearing the same clothes. And now we have ten, we dress them like this because we don't want to take other children home by mistake. When there are other children among ours, it is easy to see them because their clothes are different.
