【題目】根據(jù)板塊構(gòu)造學說,下列說法正確的是( )
A. 海洋和陸地的分布是固定不動的 B. 地球表面由整體的一個板塊構(gòu)成
C. 板塊的交界處地殼比較穩(wěn)定 D. 世界火山、地震主要分布在板塊的交界地帶
【答案】D
【解析】
試題
地球表面形態(tài)處于永不停息的運動與變化之中.地質(zhì)學家經(jīng)過長期的研究,提出了板塊構(gòu)造學說,認為全球由六大板塊組成,一般來說板塊內(nèi)部比較穩(wěn)定,板塊與板塊交界地帶,地殼比較活躍,多火山、地震.地球表面形態(tài)處于永不停息的運動與變化之中,海洋可以變成陸地,陸地可以變成海洋,因為海陸變遷需要漫長的時間,所以人們短期內(nèi)察覺不到.實際上海洋和陸地的分布是不斷變化的,所以A錯。板塊構(gòu)造學說認為全球由六大板塊組成,所以B錯。 一般來說板塊內(nèi)部比較穩(wěn)定,板塊與板塊交界地帶,地殼比較活躍,多火山、地震,所以C錯。 一般來說板塊與板塊交界地帶,地殼比較活躍,多火山、地震,所以D對。

【題目】One day after school, I went to the teacher's office to see my teacher, but nobody was there. As I was about to leave, I noticed a piece of paper on the floor. I picked it up and saw the words "FINAL-TERM EXAMINATION" at the top. I put the paper into my school bag secretly and ran out of the room.
After I came back home, I took out the paper quickly. It was the exam paper of my worst subject, History. I felt excited. My heart beat fast. I took out my History book and started working on the answer. I had never answered any questions so seriously.

"My History teacher always encouraged me to work hard and get better grades, but I let him down time and time again. This time I will give him a big surprise," I thought.
When the teacher said we could start, I turned the paper over. To my surprise, all the questions were different. Later I felt nervous. In the end, I almost left the paper undone. After the exam, I ran to the toilet, took out the paper and carefully read it from the top. Oh! It was last year's exam paper. I read all the questions but I hadn't read the date.
