Until recently, scientists had mapped only about 20 percent of the sea floor. But our knowledge of the deep seas is changing because of information from satellites. Scientists have produced a new map that provides a detailed picture of the oceans. The map is expected to help oceanographers (海洋学家), industry and governments.
The new map is twice as detailed as the map made 20 years ago. David Sandwell is a geophysics professor at the University of California. He and other scientists worked on the mapping project. He says they turned to space to look deeper into the ocean.
The scientists collected and studied information from two satellites. Some of the data came from the European Space Agency’s Cryo-2 satellite. It was placed in Earth's orbit to watch sea ice. The other satellite is the American space agency's Jason-1. It is studying the surface of the oceans. Scientists combined the satellite data with images gathered by sonar (声波定位仪) equipment on ships. Sonar works by sending sound waves through the water. When the sound waves hit an object, its presence is confirmed.
The new map shows the sea floor as it has never been seen before. It shows thousands of underwater mountains and places where continents pulled apart. It shows where earthquakes were active many years ago. They all are buried deep underneath the ocean floor.
David Sandwell says the map is a powerful tool for fisheries, those interested in protecting the environment and for oil exploration.
“The petrol exploration industry is interested in how to reconnect the continents, bring them back together tectonically so you can map the basins on one continental edge—say, Africa—and use that to establish where the similar basin would be on the other continental edge in South America.”
If scientists know that information, they may be able to find oil fields. The new data also will help scientists improve their estimates of ocean depths. This information can help ships travel safely and improve military operations and scientific projects worldwide.
Mr. Sandwell thinks scientists will make many more discoveries as they examine the new map and the information it provides.
1.Which one is not mentioned about the benefits brought by the new map?
A. Fisheries. B. Scientific projects.
C. Ship manufacture. D. Oil exploration.
2.What can we know about the new map?
A. It shows where earthquakes will happen.
B. It will be helpful to industry and governments.
C. It is three times as detailed as the old one years ago.
D. It shows the sea floor as it has ever been seen before.
3.The text is likely to appear in _________.
A. a newspaper B. an advertisement
C. a science magazine D. a finance report
4.Which of the following can be the best title for the text?
A. The detailed picture of the oceans
B. Underwater mountains and places
C. More discoveries about the oceans
D. Scientists create new maps of ocean floor

Until quite recently, I knew only three things about my father: I knew his name, David S. Johnson, Jr. I knew he was an only child, and I’d been told he was killed on April 12, 1945, somewhere in Germany.
I used to come to visit my Granny. “Daddy David and his two friends were out in the fields, making sure the way was safe for the others to follow,” she told me. “All of a sudden there was an explosion. All three of them were killed.” Granny was looking down, stroking (抚摸)one thin hand with the other. Then there were no words but silence.
I began my search and collection for information about my father as my 50th birthday and the 50th anniversary of his death drew near. I was told that the explosion had blown him to bits and I had great difficulty collecting anything I could find about him bit by bit. Bits of information about his began falling into my hands, my mind and my heart. Longing to know my father kept me connected to him. It was time to transform my longing into knowledge.
Once upon a time he was alive, and my mother and father were deeply in love. They were married, and they had a child, my brother David. Then my father left for the war.
I was born in January 1945. On February 15 my father wrote me a letter of welcome. The letter is kept in my baby book, “Dear Susan, you have a very good family. Your dad is sort of a less able person. Your mother is the most wonderful person I’ve ever known. I’ve always marveled at my great good fortune to have her and been loved by her. If you follow her words and examples, you may expect to meet life in the best possible way, and your path will always be the right one. Your father, Dave.”
Black on white paper, the words are from my father. From them I grow into a person of loyalty and love. How I long for stories that will bring him to life!
1.The writer got to know her father’s story of death from ______.
A. her father’s friends B. someone in Germany
C. her grandmother D. a little child
2.The author met difficulty finding information about her father because ______.
A. it was too late for her to start the search
B. the explosion left little about her father
C. she only found pieces of hands and legs
D. she didn’t have enough knowledge to do it
3.Which of the following statements is true?
A. Her parents had only one child B. Her father died before her birth
C. Her father was a disabled man D. The writer never saw her father
4.We know from the last paragraph that the author ______.
A. still hates her father for having left B. is curious about her father’s death
C. shows much respect for her father D. is sure that her father may survive

I recently heard a story about a famous research scientist who had made several very important medical achievements. A newspaper reporter interviewed him why he was able to be so much more creative than the average person. What set him so far apart from others?
He responded that it all came from an experience with his mother that occurred when he was about two years old. He had been trying to remove a bottle of milk from the refrigerator when he dropped the slippery bottle, spilling its contents all over the kitchen floor-a real sea of milk!
When his mother came into the kitchen, instead of shouting at him, giving him a lecture or punishing him, she said, “Robert, what a great and wonderful mess you have made! I have rarely seen such a huge pool of milk. Well,the damage has already been done. Would you like to get down and play in the milk for a few minutes before we clean it up?”
Indeed, the boy did. After a few minutes, his mother said, “You know, Robert, whenever you make a mess like this, eventually you have to clean it up and restore everything to its proper order. How would you like to do that? We could use a sponge (海绵), a towel or a mop. Which do you prefer?” He chose the sponge and together they cleaned up the spilled milk.
His mother then said, “You know, what we have here is a failed experiment in how to effectively carry a big milk bottle with two tiny hands. Let’s go out in the back yard and fill the bottle with water and see if you can find a way to carry it without dropping it.” The little boy learned that if he grasped the bottle at the top near the lip with both hands, he could make it. What a wonderful lesson!
This famous scientist then said that it was at that moment that he knew he didn’t need to be afraid to make mistakes.
1.When the mother found the kitchen floor covered with milk, she ______ .
A.gave the boy a lecture instead of shouting at him

2.The child’s experience resulted in the following BUT ______ .
A.offering the boy a chance to grasp the bottle
B.benefiting the boy all his life
C.helping the boy be more creative

高三英语单项填空简单题查看答案及解析
For some people, music is no fun at all. About four percent of the population is what scientists call “amusic.” People who are amusic are born without the ability to recognize or reproduce musical notes (音调). Amusic people often cannot tell the difference between two songs. Amusics can only hear the difference between two notes if they are very far apart on the musical scale.
As a result, songs sound like noise to an amusic. Many amusics compare the sound of music to pieces of metal hitting each other. Life can be hard for amusics. Their inability to enjoy music set them apart from others. It can be difficult for other people to identify with their condition. In fact, most people cannot begin to grasp what it feels like to be amusic. Just going to a restaurant or a shopping mall can be uncomfortable or even painful. That is why many amusics intentionally stay away from places where there is music. However, this can result in withdrawal and social isolation. “I used to hate parties,” says Margaret, a seventy-year-old woman who only recently discovered that she was amusic. By studying people like Margaret, scientists are finally learning how to identify this unusual condition.
Scientists say that the brains of amusics are different from the brains of people who can appreciate music. The difference is complex, and it doesn’t involve defective hearing. Amusics can understand other nonmusical sounds well. They also have no problems understanding ordinary speech. Scientists compare amusics to people who just can’t see certain colors.
Many amusics are happy when their condition is finally diagnosed (诊断). For years, Margaret felt embarrassed about her problem with music. Now she knows that she is not alone. There is a name for her condition. That makes it easier for her to explain. “When people invite me to a concert, I just say, ‘No thanks, I’m amusic,’” says Margaret. “I just wish I had learned to say that when I was seventeen and not seventy.” (335 words)
1.Which of the following is true of amusics?
A.Listening to music is far from enjoyable for them.
B.They love places where they are likely to hear music.
C.They can easily tell two different songs apart.
D.Their situation is well understood by musicians.
2.According to paragraph 3, a person with “defective hearing” is probably one who __________.
A.dislikes listening to speeches
B.can hear anything nonmusical
C.has a hearing problem
D.lacks a complex hearing system
3.In the last paragraph, Margaret expressed her wish that __________.
A.her problem with music had been diagnosed earlier
B.she were seventeen years old rather than seventy
C.her problem could be easily explained
D.she were able to meet other amusics
4.What is the passage mainly concerned with?
A.Amusics’ strange behaviours.
B.Some people’s inability to enjoy music.
C.Musical talent and brain structure.
D.Identification and treatment of amusics.
