“I will never find time to learn this difficult lesson，” said Robert to Frank as they left school.
“I can't do it by tomorrow . ”
“You have ten minutes before lunch. Why not begin right away？” asked his brother.
“Ten minutes! That's nothing. Besides, I must have a run with Rover now，” replied Robert.
After lunch, the two boys walked to school again. Frank took out his book and began to learn part of it while he walked along. “What a bookworm(书呆子)！” said Robert, laughing. He looked for birds' nests in the trees all the way to school.
