Scientists have found what look like caves on Mars(火星), and say they could be protecting life from the planet’s terrible environment.
The first caves discovered beyond the Earth appear as seven mysterious black dots on the pictures sent back by NASA’s Mars Odyssey orbiter. Each as large as a football field, they may be openings into natural caves below the Martian surface.
“If there is life on Mars, there is a good chance you’d find it in caves,” said Jut Wynne, one of the researchers who noticed the features while working on a US Geological Survey Mars Cave Detection Program.
Jonathan Clarke, a geologist with the Mars Society of Australia, yesterday described the discovery as exciting.
One photo taken at night by an infrared imager(紅外線成像器) showed one hole to be unusually warm, suggesting hot air trapped during the day is flowing out.
“I said: ‘Wow, that’s a cave’” Dr. Clarke said excitedly. “People have been looking for these for a long time; now we have found them.”
He agreed such caves would be perfect places to hunt for life escaping from the bitterly cold, radiation-soaked(充滿輻射的), dry surface.
“Tiny drops of water could collect inside,” he said. “If there are gases coming out, they could provide energy for a whole range of bacteria. A cave is also a protection from radiation; the surface of Mars is exposed to high levels of space radiation.”
The caves probably formed when tube-shaped lave flows(管狀巖漿流) spread across the planet long ago. The outside of the tubes cooled, forming solid walls, while something hotter inside allowed the remaining have to flow out, forming caves.
What does the passage mainly talk about?
A. How the caves were formed on Mars. B. How scientists found these caves on Mars.
C. Caves on Mars may be full of hot air or a sign of life.
D. Scientists have completely recognized the surface of Mars.
We can learn from the passage that .
A. water has already been found on Mars B. the scientists found all the caves at night
C. it is certain that there is life in these caves
D. the surface of Mars is bitterly cold, radiation-soaked and dry
According to the passage, Dr. Clarke was so excited because .
A. such caves could provide energy for life B. they had finally found the caves on Mars
C. such caves would be perfect places to hunt for life
D. scientists had long been looking for these caves
Necessary conditions for life on Mars mentioned in the passage may include .
A. lava and energy B. water and radiation from space
C. gases and lava D. water and protection from radiation

For hundreds of years humans have dreamed of finding life on distant planets.Now the hope of discovering real evidence of life has greatly increased.
NASA's Mars detector（探測器）,Opportunity,succeeded in finding signs that water once existed on the planet.Opportunity landed on Mars in January.Scientists now believe that the planet could once have supported life.
This discovery was chosen by ?Science?,one of the world's leading magazines,as the most important scientific achievement of 2004 last Friday.
“This little,wheeled,one-armed box went around another planet and has done something no human has ever managed,” according to ?Science?.“It has discovered another place in the universe where life could once have existed.
“Although we still can't say that life could have existed in this environment,it is now certain that there was water on Mars,”said Steve Squyres,one of the scientists working on the Mars mission.The evidence comes from pictures and chemical readings taken by Opportunity.It includes marks on rocks like those caused by following water on Earth and salty chemicals like those found in dried-out sea-beds.Scientists said the new evidence proved beyond doubt that water has existed on Mars.But it is still unknown whether the water was like an ocean or just ice.
While Opportunity has not found any signs of life,the presence of water means life is possible.“In everything we know about life on Earth,there is no example without liquid water,” Squyres said.“So water is important for the search for life on Mars.”
Researchers agree that a future mission（任務） should bring back physical samples（樣品）.But some scientists worry about the risk that this could introduce dangerous foreign creatures to Earth.“The problem here is how to get the samples back,”Squyres replied.“I think it is our responsibility to limit any risk.”
What proved that water existed on Mars?
A.The physical samples with salty chemicals.
B.The marks on rocks and salty chemicals.
C.Scientific achievements of 2004.
D.Creatures from Mars.
Which of the following is true according to the text?
A.It is now certain that there was water on Mars.
B.The water on Mars was like an ocean.
C.Evidence of life on Mars has been found.
D.Search for life on Mars is a great risk to humans.
How did scientists draw the conclusion that there was water on Mars?
A.The world's leading magazine has announced the fact.
B.Scientists have taken many pictures and chemical readings on the Mars.
C.Astronauts have got some rocks from Mars.
D.Scientists have made a study of the pictures and readings sent back by Mars detector.
It can be inferred that,if the creatures from Mars came to earth,_________.
A.they would be kind to humans
B.they would be cruel to humans
C.they would be a great danger to Earth
D.it would be hard to say whether it would be good news or bad news
