【題目】喜馬拉雅山脈是世界上最高大的山脈，至今它還在不斷升高的原因是

A.亞歐板塊和印度洋板塊不斷張裂B.印度洋板塊不斷擠壓亞歐板塊

C.非洲板塊和印度洋板塊不斷張裂D.非洲板塊不斷擠壓印度洋板塊

【答案】B

【解析】

根據(jù)地質學家經(jīng)過長期研究，又提出了板塊構造學說。板塊構造學說認為，地球巖石圈是由板塊拼合而成的。全球主要有六大板塊，其中太平洋板塊幾乎全部是海洋，其余板塊既包括大陸，又包括海洋。海洋與陸地的相對位置是不斷變化的，進行分析解答。

一般來說，板塊的內部比較穩(wěn)定，板塊與板塊交界的地帶，有的張裂拉伸，有的碰撞擠壓，地殼比較活躍；喜馬拉雅山位于印度洋板塊與亞歐板塊的交界地帶，印度洋板塊不斷擠壓亞歐板塊，致使喜馬拉雅山脈不斷升高。故選：B。

【題目】 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(營救) Jim—a slave（奴隸）.

“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（子彈）in my leg, it was a great adventure.
