The year 3700, Earth is far too hot for any human to call it home. On this planet at least, man is nothing more than a memory--if there is anything left to remember the "wise man". But what about our wisdom--will any of it survive us?

The conventional answer is no. Knowledge requires a knower, and there will be no knowing minds around then. But if information survives, perhaps in books or hard drives, maybe the knowledge isn't quite dead but dormant(休眠), ready to become alive with the help of other minds that develop over time or come to visit Earth in the distant future.

At first sight, that seems to be reasonable: after all, we have done similar things with past knowledge. For example, we saved an ancient computer from a ship destroyed at sea off the southern coast of Greece, and succeeded in finding the meaning of Egyptian hieroglyphics(象形文字). Careful work can bring previously lost wisdom back to life.

However, the key point is that there is a certain cultural continuity with those ancient times that allows us to reason and make progress in the dark: we know we are dealing with the legacy(遗产)of other humans. Without that link, the survival of objects and raw data doesn't guarantee the survival of knowledge. And a lack of continuity in language with any future intelligence would be a barrier. Knowledge is closely connected with language. When a language dies out, we can lose systems of reasoning that they contain. If that's lost, then it can't be recovered.

All this means that other minds might not be able to fully make human knowledge alive when we are gone. It is better to concentrate on not dying out in the first place.

1.How many opinions are mentioned in Para.2?

A. One.

B. Two.

C. Three.

D. Four.

2.What does the underlined phrase "similar things" in Para. 3 probably refer to?

A. Making lost wisdom alive again.

B. Rescuing disappearing knowledge.

C. Preserving future knowledge.

D. Gaining new knowledge.

3.How can we make knowledge survive?

A. We know a lot about human beings.

B. We learn ways to draw conclusions.

C. We have a certain cultural continuity.

D. We protect the legacy of other humans.

4.What's mainly talked about in the text?

A. Can human beings live on?

B. Will our knowledge survive us?

C. What will the earth be like in the future?

D. How can we protect our culture?

The year 3700， Earth is far too hot for any human to call it home． On this planet at least， man is nothing more than a memory - if there is anything left to remember the"wise man"． But what about our wisdom -will any of it survive us？

The conventional answer is no． Knowledge requires a knower， and there will be no knowing minds around then． But if information survives， perhaps in books or hard drives， maybe the knowledge isn't quite dead but dormant （休眠）， ready to become alive with the help of other minds that develop over time or come to visit Earth in the distant future．

However， the key point is that there is a certain cultural continuity with those ancient times that allows us to reason and make progress in the dark： we know we are dealing with the legacy （遗赠） of other humans．

We know more about the surface of the planet Mars than we know about what is at the bottom of Earth’s oceans.

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, 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 Scripps Institution of Oceanography 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. He spoke to VOA on SKYPE.

“The way we’re doing that is to use a satellite altimeter (高度计), a radar to map the topography (地貌) of the ocean surface. Now that seems sort of strange that you’d map the topography of the ocean surface when you really want to get at the sea floor. But, the ocean surface topography has these bumps and dips due to gravitational effects that mimic what’s on the sea floor.”

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 ( 声呐：利用声波探测水下物体的装置或系统) equipment on ships. Sonar works by sending sound waves through the water. When the sound waves hit an object, its presence is confirmed.

“That enables us to look at smaller-scale features and also features that are buried by sediments in the ocean basins.”

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.

In one place, three mountain ridges join at the same area. Huge tectonic (构造的) plates can be seen clearly there.

1.The passage is likely to _____.

A. be an advertisement　　　　　　　　　　　　 B. appear on VOA

C. make a comment on radar　　　　　　　　　　 D. appear on SKYPE

2.What will be mentioned in the following paragraph, according to the last paragraph? _____.

A. The detailed information about the place.

B. The more important thing in the ocean.

C. The things buried in the ocean.

D. Scientists told SKYPE they will explore at the same area.

3.Scientists collected and studied information by _____.

A. the European Space Agency’s Cryo-2 satellite

B. the American space agency’s Jason-1

C. sonar equipment on ships

D. the Cryo-2 and the Jason-1

4. What’s the best title of the passage? _____.

A. Scientists Create New Maps of Ocean Floor

B. Scientists Knows More Oceans Than Mars

C. Oceans Will Provide Us With Maps

D. People Knows Easily About Mars
