brother Michael ran out of his room,   22  a pen in his right hand and a piece of paper in the other.

“Betty, can you help me with my   23  for school? It’s about the seven   24  of the world.” He said.

“Look, not right now! I’m very busy.” I said. “You’re always busy! You’re always like that!” he replied.

The most valuable things in life are the ones that we   38  take for granted. These things don’t take the form of big houses or beautiful   39 . The most wonderful things in the world are immaterial(非物质的)   40  they can never be developed by human art, skill or effort.
