1 . I’m a mother of three and a psychologist. Recently, I come to understand what makes childhood valuable in its own right.

One day, when I went to get my 7-year-old son from soccer ________, the kid ________ me with a downcast face. The coach had ________ him for not focusing on his soccer drills. He walked out of the school with his head and shoulders ________ down. He seemed wrapped in ________. But just before he reached the car door, he suddenly stopped, crouching (蹲伏) down to ________ something on the sidewalk. His ________ went down lower and lower, and then, with complete joy he called out, “Mum. Come here. This is the ________ bug (虫子) I’ve ever seen. It has, like a million ________. It’s amazing.” He looked up at me, his features overflowing with energy and ________. “Can’t we ________ here for just a minute? I want to find out what he does with all those legs.”

The traditional view of such a moment is that it is ________, or a waste of valuable time. Yet at that moment it suddenly dawned on me that what sets children apart from adults is not their ignorance (无知) but their ________ for joy. Children’s ability to become deeply ________ in something and get great pleasure is what adults spend the rest of their lives ________.
