【题目】 I saw Tom Sawyer on the way to the town. When he saw me he looked frightened. “Huck! Why have you come back to scare me? I never hurt you,” he said. “I haven 't come back. Tom. I've never been away.”

“Aren't you a ghost?”

“No, it was a trick.” I said.

Then I told him that I wanted to rescue(营救) Jim—a slave（奴隶）.

“I'll help you,” Tom replied excitedly. He loved an adventure more than anything else in the world.

When we got back to the farm, Tom said that he was Sid, Tom's younger brother. Aunt Sally was surprised to see him but was happy to have his two nephews(侄子).

That night, Tom and I went out to look for Jim. There were lots of huts in the garden. One of the huts was locked. So we guessed Jim was locked in the hut. We dug a tunnel under the wall of the hut that night. Finally, we succeeded. Jim was very surprised to see us.

“Hello, Jim!” Tom said. “But we aren't ready to do it yet, you'll have to wait a couple of days.” “Don't worry! you'll soon be free!”

Then we came back and talked about a plan to get away.

“I'm going to write a letter to Uncle Silas,” Tom said.” “Of course I won't sign it. It'll be anonymous(匿名的). I’m going to warn him that somebody's planning to steal the runaway slave .”I didn't understand why we had to look for trouble but I didn't say anything. “Well, Huck, if Uncle Silas knows, he'll try to stop the thieves,” says Tom.

So Tom wrote the letter and I put it under the front door. Uncle Silas found it in the morning. After reading it, he went out at once. At night, we successfully rescued Jim. We are very happy because Jim is a free man now. Though Tom got a bullet（子弹）in my leg, it was a great adventure.
