One morning when Liu Tao woke up, he jumped out of his bed happily. He had a1 idea. He would build a tree house! Liu Tao asked his dad, "Is it OK if I build a tree house in the old tree outside the 2?"
"It's not only OK," said Dad. "I'll even 3 you build it."
When they finished breakfast, both of them went out to the 4 in their garden and began to measure (测量). Then they got some boards and started to 5 them with a saw (锯子). When the pieces were ready, Liu Tao climbed up in the tree and Dad handed him the boards. They fixed the boards to some 6 branches.
Some birds were singing around them but they had no time to enjoy the 7 of the birds. Building a tree house was much work and lots of things were waiting for Liu Tao and his dad. They worked the whole 8. They even put a roof over the tree house so that it could keep9 in the rain. At last, they finished just before dark.
Early that night, Liu Tao asked his brother if he could borrow a sleeping bag.
"Sure," said the brother. "But 10 I go with you?"
"Of course, you can." Liu Tao smiled. Then they both ran upstairs to get ready.
