　 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?”

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.
