第一节：从四个选项中选出正确答案。
A
The first breath-taking pictures of the Earth taken from space showed it as a solid ball covered by brown land masses and blue-green oceans. We had never seen the Earth from that distance before. To us, it appeared as though the Earth had always looked that way and always would. Scientists now know, however, that the surface of the Earth is not as permanent as we had thought.
Scientists explain that the surface of our planet is always moving. Continents moves about the Ea rth like huge ships at sea. They float on pieces of the Earth’s outer skin. New outer skin is created as melted rock pushed up from below the ocean floor. Old outer skin is destroyed as it rolls down into the hot area and melts again.
Only since the 1960s have scientists really began to understand that the planet Earth is a great living machine. Some experts have said this new understanding is one of the most important revolutions in scientific thought. The revolution is based on the work of scientists who study the movement of the continents—a science called plate tectonics.
The modern story of plate tectonics begins with the German scientist Alfred Wegener. Before World War One, Wegener argued that the continents had moved and were still moving. He said the idea first occurred to him w hen he observed that the coastlines of South America and Africa could fit together like two pieces of a puzzle. He proposed that the two continents might have been one and then split apart.
Wegener was not the first person to wonder about the shape of the continents. About 500 years ago, explorers thought about it when they made the first maps of America. The explorers noted the east coast of North America and South America would fit almost exactly into the west coast of Europe and South Africa. What the explorers did not do, but Wegener did, was to investigate the idea that the continents move.
36. What does the writer mainly tell us in the passage?
A. The first breath-taking pictures of the Earth taken from space.
B. Hum an’s recognition of the earth’s surface.
C. The German scientist Alfred Wegener.
D. The early explorers’ discovery.
37. Which of the following is true according to the passage?
A. We didn’t see the Earth from far away until we saw the picture taken in t he space.
B. Our ancient thought that the surface of the earth is still.
C. Alfred Wegener was not the first person to investigate the idea that the continents move.
D. The coastline of India and Africa fit together.
38. The last word of the third paragra ph “tectonics” mean “________”.
A. study of construction
B. study of architecture
C. earth surface
D. structural geology
39. What did the explorers find?
A. The coastlines of South America and Africa could fit together.
B. The coastlines of North America and Africa could fit together.
C. The east coastlines of North America and the west coast of Europe could fit together.
D. The coastlines of North America and India could fit together.
B
“The first and best of victories for a man is to conquer himself; to be conquered by himself is, of all things, the most shameful,” says Plato. Self-control is at the root of all the advantages. Let a man give in to his impulses(冲动) and feelings, and from that moment he gives up his moral(道德) freedom.
A single angry word has lost many friends. When Socrates found in himself any temper or anger, he would check it by speaking low in order to control himself. If you are conscious of being angry, keep your mouth shut so that you can hold back rising anger. Many a person has dropped dead in great anger. Fits of anger bring fits of disease. “Whoever the gods would destroy they first make them mad.” “Keep cool,” says Webster, “anger is not argument.” “Be calm in arguing,” says George Herbert, “for fierce ness(狂怒) makes error a fault.”
To be angry with a weak man is to prove that you are not strong yourself. “Anger,” says Pythagoras, “brings with folly(愚蠢) and ends with regret.” You must measure the strength of a man by the power of the feelings he conquers, not by the power of those that conquer him.
Self-control is man’s last and greatest victory.
If a man lacks self-control he seems to lack everything. Without it he can have no patience, no power to govern himself; he can have no self-confidence, for he will always be controlled by his strongest feeling. If he lacks self-control, the very backbone and nerve of character are lacking also.
40. What’s the main idea of the passage?
A. The importance of self- control.
B. How to conquer oneself?
C. The relati on between a man’s moral freedom and his feelings.
D. A man should keep cool.
41. What’s the meaning of “whoever the gods would destroy they first make them mad”?
A. If you are mad, the gods will kill you.
B. If you lose your temper first, gods will kill you first.
C. If you can’t control yourself, you will be crazy.
D. If the gods want to kill you, they will make you mad first.
42. Which of the following is NOT true, according to passage?
A. The first and best of victories is for a man to conquer himself.
B. You will make a small mistake serious if you don’t keep cool.
C. You must measure a man’s strength by the power of the feelings which conquer him.
D. Anger brings with folly and ends with regret.
43. Which of the following can’t help yo u avoid anger, according to the passage?
A. Be calm in arguing.
B. Check your temper or anger by speaking low.
C. Keep your mouth shut.
D. Try to make the other angry first.
C
He may be still young, but he may surprise you! If you ask around, many would say that the music world has a new leader---the real king is Jay Chou. As a child, Jay Chou was never too good at his subjects, and when he didn’t get into any college, a lot of people said that he won’t be very hopeful in life. His mom always worried about his future, but he never did. “I knew I still had music to depend on. For everything else, I always believe in myself, but it is for my musical talent (天才) that I am so sure of myself.” He said . Growing up in a single-parent family, Jay lived a lonely childhood. Without many friends, He had a habit of daydreaming, dreaming into his world of music.
So how did Jay get into music? At the age of three, he started learning to play the piano. His mother was very strict to make sure he practiced hard. Later, he learned to play the cello（大提琴）.
With all the musical talent, it isn’t surprising that Jay started out as a song writer. Since the age of sixteen, he has been writing songs for many of the most popular singers. Today, he has already written for some of the most popular Asian singers, including Coco Lee, Jacky Wu, etc.
It was only in 2000 that Jay put out his own album “Jay”. Jay’s soft and smooth
voice is especially gentle and calm, making this first album an immediate hit. Each song in the album has its own, different style, and skillfully, Jay used his voice to suit each song’s character.
Lyrics（歌词）of Jay’s songs all have a special touch. In his song “Dad, I am back”, the subject is a broken family. “I heard that after war, there is peace. Why do I always see my dad beating my mom? Since I was young, you told me to learn from you, use you as a model. So much pretense (借口). How do you expect me to be like you!”
44. Whic h of the following statements is true about Jay Chou?
A. He didn’t do well at school.
B. He worried about his future at school.
C. His father died when Jay was young.
D. He had many friends around him.
45.Jay Chou got into music__________.

47. What do we know about the song “Dad, I am Back”?
