Not long ago, there was a story in Russia about ZHUOYA and SHULA. They were sister and brother. They were in 1 same class of a middle school. They studied hard. They were　 2　 strict 　3 themselves. Their homework was given the day before. SHULA was clever. He had done his homework earlier. But ZHUOYA hadn’t yet. The next afternoon she went on doing hers.

SHULA thought his sister maybe couldn’t finish some of the exercises. So he put his exercise-book with answers on his sister’s desk before ZHUOYA came in the classroom, and went out quietly to play. A few minutes later, ZHUOYA came in and saw her brother’s exercise-book on her desk. But she had never looked at it all. She sat on her seat, thinking and thinking. Five minutes, ten minutes, half an hour had 4 . An hour and a half 5 , she worked out all problems at last and handed it in on time that afternoon. How happy she was!

“Why not copy my key down in 6 , sister?” asked SHULA with a smile. “No, I didn’t. I must use my head and try my 　7 to 　8 all by myself. I’m sure, I can 9 a way. I don’t like to be lazy in 10 homework,” answered ZHUOYA.
