　 When his mother came in, 45 shouting at him, she said, “Robert, what a great mess(一团糟) you have made! I have never seen such a big puddle(水坑) of milk. Would you like to get down and play in the milk for a few minutes 　46 we clean it up?”

　 Indeed, he did. After a few minutes, his mother said, “Robert, when you make a mess like this, you have to clean it up at last. So, 　47 would you like to do that? We would use a towel or a mop. Which do you prefer?” He chose the towel and together they cleaned up the milk.

　 His mother then said, “We had a failed 48 in how to carry a big milk bottle with two small hands in the kitchen. Let’s go out and fill the bottle with water and see if you can 49 a way to carry it without dropping it.” The little boy learned that if he held the bottle at the top near the lip(杯口) with both hands, he could carry it without dropping it.
