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 （盆地）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 is based on the data gathered by the spaceships.
3.The text is likely to appear in _________.
A. a sicence fiction 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

Our class recently has had a heated discussion about if the historic old buildings should be tear down. Opinions varies from one to another. Some students support the protection of those buildings so they are carriers of history through which the future generations can deep understand the development of our city. Beside, the historic old buildings can also arouse people’s love for the city.
In the contrary, some other students think that the old buildings may hold back the development of economy and the process of modernization. It may affect the beauty of the city.
As far I’m concerned, I approve of（赞成） the former opinion. But if a building is worth of little, it may be proper to demolish(摧毁) it and make better use of that area. We should just weight the advantages and disadvantages.

When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.
People who are near-sighted can only see things that are very close to their eyes. Everything else seems blurry. Many people who do a lot of work, such as writing, reading and sewing become near-sighted. People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distances as people with two eyes.
1.We should take good care of our eyes .
A.only when we can see well
B.only when we cannot see perfectly
C.even if we can see well
D.only when we realize how important our eyes are
2.The underlined word blurry in the second paragraph probably means .
A.obvious B.possible C.clear D.unclear
3.Having two eyes instead of one is particularly useful for .
A.seeing at night
B.seeing objects far away
C.looking over a wide area
D.judging distances
4.People who suffer from astigmatism have .
A.one eye bigger than the other
B.eyes that are not exactly the right shape
C.a difficulty that can be corrected by an operation
D.an eye difficulty that cannot be corrected by glasses
