B
The next day they set off again very early. They walk a few miles and then come to a big ditch(沟). It's very wide. There are a lot of rocks(岩石) in the ditch.
"How can we cross the ditch?" Dorothy asks her friends.
"We can't fly over it," the Scarecrow says. "And we can't jump over it. So we must stay here."
The Lion looks at the ditch and says, "I can jump over it."
"Can you?" the Scarecrow says. "That's good! You can take us across on your back, one by one."
"Who wants to go first? "the Lion says. He's a little afraid first but he wants to help his friends.
"Me!" the Scarecrow says and he gets on the Lion's back. The Lion jumps across the ditch easily. Then he jumps back and takes Dorothy and Toto. Finally he takes the Tin Woodman(铁皮人) across the ditch.
The Lion is tired after his five big jumps.
"Let's have a rest before we start walking again," he says.
Later in the afternoon they come to a wide river. They can see a beautiful country on the other side of it.
There are green fields and a lot of flowers. They can also see the yellow brick(砖) road.
